- Writes the specified number of bytes from the input buffer to the block.
-
- The Write() function writes the specified number of bytes from
- the provided buffer to the specified block and offset. If the
- firmware volume is sticky write, the caller must ensure that
- all the bits of the specified range to write are in the
- EFI_FVB_ERASE_POLARITY state before calling the Write()
- function, or else the result will be unpredictable. This
- unpredictability arises because, for a sticky-write firmware
- volume, a write may negate a bit in the EFI_FVB_ERASE_POLARITY
- state but cannot flip it back again. In general, before
- calling the Write() function, the caller should call the
- EraseBlocks() function first to erase the specified block to
- write. A block erase cycle will transition bits from the
- (NOT)EFI_FVB_ERASE_POLARITY state back to the
- EFI_FVB_ERASE_POLARITY state. Implementations should be
- mindful that the firmware volume might be in the WriteDisabled
- state. If it is in this state, the Write() function must
- return the status code EFI_ACCESS_DENIED without modifying the
- contents of the firmware volume. The Write() function must
- also prevent spanning block boundaries. If a write is
- requested that spans a block boundary, the write must store up
- to the boundary but not beyond. The output parameter NumBytes
- must be set to correctly indicate the number of bytes actually
- written. The caller must be aware that a write may be

- * `incontents 50 arm_abi Hypercall Calling Convention
- *
- * A hypercall is issued using the ARM HVC instruction.
- *
- * A hypercall can take up to 5 arguments. These are passed in
- * registers, the first argument in x0/r0 (for arm64/arm32 guests
- * respectively irrespective of whether the underlying hypervisor is
- * 32- or 64-bit), the second argument in x1/r1, the third in x2/r2,
- * the forth in x3/r3 and the fifth in x4/r4.
- *
- * The hypercall number is passed in r12 (arm) or x16 (arm64). In both
- * cases the relevant ARM procedure calling convention specifies this
- * is an inter-procedure-call scratch register (e.g. for use in linker
- * stubs). This use does not conflict with use during a hypercall.
- *
- * The HVC ISS must contain a Xen specific TAG: XEN_HYPERCALL_TAG.
- *
- * The return value is in x0/r0.
- *
- * The hypercall will clobber x16/r12 and the argument registers used
- * by that hypercall (except r0 which is the return value) i.e. in
- * addition to x16/r12 a 2 argument hypercall will clobber x1/r1 and a
- * 4 argument hypercall will clobber x1/r1, x2/r2 and x3/r3.
- *
- * Parameter structs passed to hypercalls are laid out according to
- * the Procedure Call Standard for the ARM Architecture (AAPCS, AKA
- * EABI) and Procedure Call Standard for the ARM 64-bit Architecture
- * (AAPCS64). Where there is a conflict the 64-bit standard should be
- * used regardless of guest type. Structures which are passed as
- * hypercall arguments are always little endian.
- *
- * All memory which is shared with other entities in the system
- * (including the hypervisor and other guests) must reside in memory
- * which is mapped as Normal Inner-cacheable. This applies to:
- * - hypercall arguments passed via a pointer to guest memory.
- * - memory shared via the grant table mechanism (including PV I/O
- * rings etc).
- * - memory shared with the hypervisor (struct shared_info, struct
- * vcpu_info, the grant table, etc).
- *
- * Any Inner cache allocation strategy (Write-Back, Write-Through etc)
- * is acceptable. There is no restriction on the Outer-cacheability.

-/*
- * `incontents 55 arm_hcall Supported Hypercalls
- *
- * Xen on ARM makes extensive use of hardware facilities and therefore
- * only a subset of the potential hypercalls are required.
- *
- * Since ARM uses second stage paging any machine/physical addresses
- * passed to hypercalls are Guest Physical Addresses (Intermediate
- * Physical Addresses) unless otherwise noted.
- *
- * The following hypercalls (and sub operations) are supported on the
- * ARM platform. Other hypercalls should be considered
- * unavailable/unsupported.
- *
- * HYPERVISOR_memory_op
- * All generic sub-operations.
- *
- * In addition the following arch specific sub-ops:
- * * XENMEM_add_to_physmap
- * * XENMEM_add_to_physmap_batch
- *
- * HYPERVISOR_domctl
- * All generic sub-operations, with the exception of:
- * * XEN_DOMCTL_iomem_permission (not yet implemented)
- * * XEN_DOMCTL_irq_permission (not yet implemented)
- *
- * HYPERVISOR_sched_op
- * All generic sub-operations, with the exception of:
- * * SCHEDOP_block -- prefer wfi hardware instruction
- *
- * HYPERVISOR_console_io
- * All generic sub-operations
- *
- * HYPERVISOR_xen_version
- * All generic sub-operations
- *
- * HYPERVISOR_event_channel_op
- * All generic sub-operations
- *
- * HYPERVISOR_physdev_op
- * No sub-operations are currenty supported
- *
- * HYPERVISOR_sysctl
- * All generic sub-operations, with the exception of:
- * * XEN_SYSCTL_page_offline_op
- * * XEN_SYSCTL_get_pmstat
- * * XEN_SYSCTL_pm_op
- *
- * HYPERVISOR_hvm_op
- * Exactly these sub-operations are supported:
- * * HVMOP_set_param
- * * HVMOP_get_param
- *
- * HYPERVISOR_grant_table_op
- * All generic sub-operations
- *
- * HYPERVISOR_vcpu_op
- * Exactly these sub-operations are supported:
- * * VCPUOP_register_vcpu_info
- * * VCPUOP_register_runstate_memory_area
- *
- *
- * Other notes on the ARM ABI:
- *
- * - struct start_info is not exported to ARM guests.
- *
- * - struct shared_info is mapped by ARM guests using the
- * HYPERVISOR_memory_op sub-op XENMEM_add_to_physmap, passing
- * XENMAPSPACE_shared_info as space parameter.
- *
- * - All the per-cpu struct vcpu_info are mapped by ARM guests using the
- * HYPERVISOR_vcpu_op sub-op VCPUOP_register_vcpu_info, including cpu0
- * struct vcpu_info.
- *
- * - The grant table is mapped using the HYPERVISOR_memory_op sub-op
- * XENMEM_add_to_physmap, passing XENMAPSPACE_grant_table as space
- * parameter. The memory range specified under the Xen compatible
- * hypervisor node on device tree can be used as target gpfn for the
- * mapping.
- *
- * - Xenstore is initialized by using the two hvm_params
- * HVM_PARAM_STORE_PFN and HVM_PARAM_STORE_EVTCHN. They can be read
- * with the HYPERVISOR_hvm_op sub-op HVMOP_get_param.
- *
- * - The paravirtualized console is initialized by using the two
- * hvm_params HVM_PARAM_CONSOLE_PFN and HVM_PARAM_CONSOLE_EVTCHN. They
- * can be read with the HYPERVISOR_hvm_op sub-op HVMOP_get_param.
- *
- * - Event channel notifications are delivered using the percpu GIC
- * interrupt specified under the Xen compatible hypervisor node on
- * device tree.
- *
- * - The device tree Xen compatible node is fully described under Linux
- * at Documentation/devicetree/bindings/arm/xen.txt.

- * of interest is signalled by transitioning this bit from 0 to 1.

- * notifications are masked until the bit is cleared again (therefore,
- * guests must check the value of the bit after re-enabling event
- * delivery to ensure no missed notifications).
- *
- * Event notifications can be masked by setting a flag; this is
- * equivalent to disabling interrupts and can be used to ensure

- *
- * Xen's grant tables provide a generic mechanism to memory sharing
- * between domains. This shared memory interface underpins the split
- * device drivers for block and network IO.
- *
- * Each domain has its own grant table. This is a data structure that
- * is shared with Xen; it allows the domain to tell Xen what kind of
- * permissions other domains have on its pages. Entries in the grant
- * table are identified by grant references. A grant reference is an
- * integer, which indexes into the grant table. It acts as a
- * capability which the grantee can use to perform operations on the
- * granter’s memory.
- *
- * This capability-based system allows shared-memory communications
- * between unprivileged domains. A grant reference also encapsulates
- * the details of a shared page, removing the need for a domain to
- * know the real machine address of a page it is sharing. This makes
- * it possible to share memory correctly with domains running in
- * fully virtualised memory.

-/* Some rough guidelines on accessing and updating grant-table entries
- * in a concurrency-safe manner. For more information, Linux contains a
- * reference implementation for guest OSes (drivers/xen/grant_table.c, see
- * http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=blob;f=drivers/xen/grant-table.c;hb=HEAD
- *
- * NB. WMB is a no-op on current-generation x86 processors. However, a
- * compiler barrier will still be required.
- *
- * Introducing a valid entry into the grant table:
- * 1. Write ent->domid.
- * 2. Write ent->frame:
- * GTF_permit_access: Frame to which access is permitted.
- * GTF_accept_transfer: Pseudo-phys frame slot being filled by new
- * frame, or zero if none.
- * 3. Write memory barrier (WMB).
- * 4. Write ent->flags, inc. valid type.
- *
- * Invalidating an unused GTF_permit_access entry:
- * 1. flags = ent->flags.
- * 2. Observe that !(flags & (GTF_reading|GTF_writing)).
- * 3. Check result of SMP-safe CMPXCHG(&ent->flags, flags, 0).
- * NB. No need for WMB as reuse of entry is control-dependent on success of
- * step 3, and all architectures guarantee ordering of ctrl-dep writes.
- *
- * Invalidating an in-use GTF_permit_access entry:
- * This cannot be done directly. Request assistance from the domain controller
- * which can set a timeout on the use of a grant entry and take necessary
- * action. (NB. This is not yet implemented!).
- *
- * Invalidating an unused GTF_accept_transfer entry:
- * 1. flags = ent->flags.
- * 2. Observe that !(flags & GTF_transfer_committed). [*]
- * 3. Check result of SMP-safe CMPXCHG(&ent->flags, flags, 0).
- * NB. No need for WMB as reuse of entry is control-dependent on success of
- * step 3, and all architectures guarantee ordering of ctrl-dep writes.
- * [*] If GTF_transfer_committed is set then the grant entry is 'committed'.
- * The guest must /not/ modify the grant entry until the address of the
- * transferred frame is written. It is safe for the guest to spin waiting
- * for this to occur (detect by observing GTF_transfer_completed in
- * ent->flags).
- *
- * Invalidating a committed GTF_accept_transfer entry:
- * 1. Wait for (ent->flags & GTF_transfer_completed).
- *
- * Changing a GTF_permit_access from writable to read-only:
- * Use SMP-safe CMPXCHG to set GTF_readonly, while checking !GTF_writing.
- *
- * Changing a GTF_permit_access from read-only to writable:
- * Use SMP-safe bit-setting instruction.

- * Feature and Parameter Negotiation
- * =================================
- * The two halves of a Xen block driver utilize nodes within the XenStore to
- * communicate capabilities and to negotiate operating parameters. This
- * section enumerates these nodes which reside in the respective front and
- * backend portions of the XenStore, following the XenBus convention.
- *
- * All data in the XenStore is stored as strings. Nodes specifying numeric
- * values are encoded in decimal. Integer value ranges listed below are
- * expressed as fixed sized integer types capable of storing the conversion
- * of a properly formated node string, without loss of information.
- *
- * Any specified default value is in effect if the corresponding XenBus node
- * is not present in the XenStore.
- *
- * XenStore nodes in sections marked "PRIVATE" are solely for use by the
- * driver side whose XenBus tree contains them.
- *
- * XenStore nodes marked "DEPRECATED" in their notes section should only be
- * used to provide interoperability with legacy implementations.
- *
- * See the XenBus state transition diagram below for details on when XenBus
- * nodes must be published and when they can be queried.
- *
- *****************************************************************************
- * Backend XenBus Nodes
- *****************************************************************************
- *
- *------------------ Backend Device Identification (PRIVATE) ------------------
- *
- * mode
- * Values: "r" (read only), "w" (writable)
- *
- * The read or write access permissions to the backing store to be
- * granted to the frontend.
- *
- * params
- * Values: string
- *
- * A free formatted string providing sufficient information for the
- * backend driver to open the backing device. (e.g. the path to the
- * file or block device representing the backing store.)
- *
- * type
- * Values: "file", "phy", "tap"
- *
- * The type of the backing device/object.
- *
- *--------------------------------- Features ---------------------------------
- *
- * feature-barrier
- * Values: 0/1 (boolean)
- * Default Value: 0
- *
- * A value of "1" indicates that the backend can process requests
- * containing the BLKIF_OP_WRITE_BARRIER request opcode. Requests
- * of this type may still be returned at any time with the
- * BLKIF_RSP_EOPNOTSUPP result code.
- *
- * feature-flush-cache
- * Values: 0/1 (boolean)
- * Default Value: 0
- *
- * A value of "1" indicates that the backend can process requests
- * containing the BLKIF_OP_FLUSH_DISKCACHE request opcode. Requests
- * of this type may still be returned at any time with the
- * BLKIF_RSP_EOPNOTSUPP result code.
- *
- * feature-discard
- * Values: 0/1 (boolean)
- * Default Value: 0
- *
- * A value of "1" indicates that the backend can process requests
- * containing the BLKIF_OP_DISCARD request opcode. Requests
- * of this type may still be returned at any time with the
- * BLKIF_RSP_EOPNOTSUPP result code.
- *
- * feature-persistent
- * Values: 0/1 (boolean)
- * Default Value: 0
- * Notes: 7
- *
- * A value of "1" indicates that the backend can keep the grants used
- * by the frontend driver mapped, so the same set of grants should be
- * used in all transactions. The maximum number of grants the backend
- * can map persistently depends on the implementation, but ideally it
- * should be RING_SIZE * BLKIF_MAX_SEGMENTS_PER_REQUEST. Using this
- * feature the backend doesn't need to unmap each grant, preventing
- * costly TLB flushes. The backend driver should only map grants
- * persistently if the frontend supports it. If a backend driver chooses
- * to use the persistent protocol when the frontend doesn't support it,
- * it will probably hit the maximum number of persistently mapped grants
- * (due to the fact that the frontend won't be reusing the same grants),
- * and fall back to non-persistent mode. Backend implementations may
- * shrink or expand the number of persistently mapped grants without
- * notifying the frontend depending on memory constraints (this might
- * cause a performance degradation).
- *
- * If a backend driver wants to limit the maximum number of persistently
- * mapped grants to a value less than RING_SIZE *
- * BLKIF_MAX_SEGMENTS_PER_REQUEST a LRU strategy should be used to
- * discard the grants that are less commonly used. Using a LRU in the
- * backend driver paired with a LIFO queue in the frontend will
- * allow us to have better performance in this scenario.
- *
- *----------------------- Request Transport Parameters ------------------------
- *
- * max-ring-page-order
- * Values: <UINT32>
- * Default Value: 0
- * Notes: 1, 3
- *
- * The maximum supported size of the request ring buffer in units of
- * lb(machine pages). (e.g. 0 == 1 page, 1 = 2 pages, 2 == 4 pages,
- * etc.).
- *
- * max-ring-pages
- * Values: <UINT32>
- * Default Value: 1
- * Notes: DEPRECATED, 2, 3
- *
- * The maximum supported size of the request ring buffer in units of
- * machine pages. The value must be a power of 2.
- *
- *------------------------- Backend Device Properties -------------------------
- *
- * discard-alignment
- * Values: <UINT32>
- * Default Value: 0
- * Notes: 4, 5
- *
- * The offset, in bytes from the beginning of the virtual block device,
- * to the first, addressable, discard extent on the underlying device.
- *
- * discard-granularity
- * Values: <UINT32>
- * Default Value: <"sector-size">
- * Notes: 4
- *
- * The size, in bytes, of the individually addressable discard extents
- * of the underlying device.
- *
- * discard-secure
- * Values: 0/1 (boolean)
- * Default Value: 0
- * Notes: 10
- *
- * A value of "1" indicates that the backend can process BLKIF_OP_DISCARD
- * requests with the BLKIF_DISCARD_SECURE flag set.
- *
- * info
- * Values: <UINT32> (bitmap)
- *
- * A collection of bit flags describing attributes of the backing
- * device. The VDISK_* macros define the meaning of each bit
- * location.
- *
- * sector-size
- * Values: <UINT32>
- *
- * The logical sector size, in bytes, of the backend device.
- *
- * physical-sector-size
- * Values: <UINT32>
- *
- * The physical sector size, in bytes, of the backend device.
- *
- * sectors
- * Values: <UINT64>
- *
- * The size of the backend device, expressed in units of its logical
- * sector size ("sector-size").
- *
- *****************************************************************************
- * Frontend XenBus Nodes
- *****************************************************************************
- *
- *----------------------- Request Transport Parameters -----------------------
- *
- * event-channel
- * Values: <UINT32>
- *
- * The identifier of the Xen event channel used to signal activity
- * in the ring buffer.
- *
- * ring-ref
- * Values: <UINT32>
- * Notes: 6
- *
- * The Xen grant reference granting permission for the backend to map
- * the sole page in a single page sized ring buffer.
- *
- * ring-ref%u
- * Values: <UINT32>
- * Notes: 6
- *
- * For a frontend providing a multi-page ring, a "number of ring pages"
- * sized list of nodes, each containing a Xen grant reference granting
- * permission for the backend to map the page of the ring located
- * at page index "%u". Page indexes are zero based.
- *
- * protocol
- * Values: string (XEN_IO_PROTO_ABI_*)
- * Default Value: XEN_IO_PROTO_ABI_NATIVE
- *
- * The machine ABI rules governing the format of all ring request and
- * response structures.
- *
- * ring-page-order
- * Values: <UINT32>
- * Default Value: 0
- * Maximum Value: MAX(ffs(max-ring-pages) - 1, max-ring-page-order)
- * Notes: 1, 3
- *
- * The size of the frontend allocated request ring buffer in units
- * of lb(machine pages). (e.g. 0 == 1 page, 1 = 2 pages, 2 == 4 pages,
- * etc.).
- *
- * num-ring-pages
- * Values: <UINT32>
- * Default Value: 1
- * Maximum Value: MAX(max-ring-pages,(0x1 << max-ring-page-order))
- * Notes: DEPRECATED, 2, 3
- *
- * The size of the frontend allocated request ring buffer in units of
- * machine pages. The value must be a power of 2.
- *
- * feature-persistent
- * Values: 0/1 (boolean)
- * Default Value: 0
- * Notes: 7, 8, 9
- *
- * A value of "1" indicates that the frontend will reuse the same grants
- * for all transactions, allowing the backend to map them with write
- * access (even when it should be read-only). If the frontend hits the
- * maximum number of allowed persistently mapped grants, it can fallback
- * to non persistent mode. This will cause a performance degradation,
- * since the the backend driver will still try to map those grants
- * persistently. Since the persistent grants protocol is compatible with
- * the previous protocol, a frontend driver can choose to work in
- * persistent mode even when the backend doesn't support it.
- *
- * It is recommended that the frontend driver stores the persistently
- * mapped grants in a LIFO queue, so a subset of all persistently mapped
- * grants gets used commonly. This is done in case the backend driver
- * decides to limit the maximum number of persistently mapped grants
- * to a value less than RING_SIZE * BLKIF_MAX_SEGMENTS_PER_REQUEST.
- *
- *------------------------- Virtual Device Properties -------------------------
- *
- * device-type
- * Values: "disk", "cdrom", "floppy", etc.
- *
- * virtual-device
- * Values: <UINT32>
- *
- * A value indicating the physical device to virtualize within the
- * frontend's domain. (e.g. "The first ATA disk", "The third SCSI
- * disk", etc.)
- *
- * See docs/misc/vbd-interface.txt for details on the format of this
- * value.
- *
- * Notes
- * -----
- * (1) Multi-page ring buffer scheme first developed in the Citrix XenServer
- * PV drivers.
- * (2) Multi-page ring buffer scheme first used in some RedHat distributions
- * including a distribution deployed on certain nodes of the Amazon
- * EC2 cluster.
- * (3) Support for multi-page ring buffers was implemented independently,
- * in slightly different forms, by both Citrix and RedHat/Amazon.
- * For full interoperability, block front and backends should publish
- * identical ring parameters, adjusted for unit differences, to the
- * XenStore nodes used in both schemes.
- * (4) Devices that support discard functionality may internally allocate space
- * (discardable extents) in units that are larger than the exported logical
- * block size. If the backing device has such discardable extents the
- * backend should provide both discard-granularity and discard-alignment.
- * Providing just one of the two may be considered an error by the frontend.
- * Backends supporting discard should include discard-granularity and
- * discard-alignment even if it supports discarding individual sectors.
- * Frontends should assume discard-alignment == 0 and discard-granularity
- * == sector size if these keys are missing.
- * (5) The discard-alignment parameter allows a physical device to be
- * partitioned into virtual devices that do not necessarily begin or
- * end on a discardable extent boundary.
- * (6) When there is only a single page allocated to the request ring,
- * 'ring-ref' is used to communicate the grant reference for this
- * page to the backend. When using a multi-page ring, the 'ring-ref'
- * node is not created. Instead 'ring-ref0' - 'ring-refN' are used.
- * (7) When using persistent grants data has to be copied from/to the page
- * where the grant is currently mapped. The overhead of doing this copy
- * however doesn't suppress the speed improvement of not having to unmap
- * the grants.
- * (8) The frontend driver has to allow the backend driver to map all grants
- * with write access, even when they should be mapped read-only, since
- * further requests may reuse these grants and require write permissions.
- * (9) Linux implementation doesn't have a limit on the maximum number of
- * grants that can be persistently mapped in the frontend driver, but
- * due to the frontent driver implementation it should never be bigger
- * than RING_SIZE * BLKIF_MAX_SEGMENTS_PER_REQUEST.
- *(10) The discard-secure property may be present and will be set to 1 if the
- * backing device supports secure discard.

- * prevent unbounded stack usage. Whatever the purpose, we expect
- * that the mask will be asserted only for short periods at a time,
- * and so the likelihood of a 'spurious' IPI is suitably small.
- * The mask is read before making an event upcall to the guest: a
- * non-zero mask therefore guarantees that the VCPU will not receive
- * an upcall activation. The mask is cleared when the VCPU requests
- * to block: this avoids wakeup-waiting races.

- * becomes pending while the channel is masked then the 'edge' is lost
- * (i.e., when the channel is unmasked, the guest must manually handle
- * pending notifications as no upcall will be scheduled by Xen).
- *
- * To expedite scanning of pending notifications, any 0->1 pending

-/**
- These are the notifications from the PCI bus driver that it is about to enter
- a certain phase of the PCI enumeration process.
-
- This member function can be used to notify the host bridge driver to perform
- specific actions, including any chipset-specific initialization, so that the
- chipset is ready to enter the next phase. Eight notification points are
- defined at this time. See belows:
-
- EfiPciHostBridgeBeginEnumeration Resets the host bridge PCI apertures
- and internal data structures. The PCI
- enumerator should issue this
- notification before starting a fresh
- enumeration process. Enumeration
- cannot be restarted after sending any
- other notification such as
- EfiPciHostBridgeBeginBusAllocation.
-
- EfiPciHostBridgeBeginBusAllocation The bus allocation phase is about to
- begin. No specific action is required
- here. This notification can be used to
- perform any chipset-specific
- programming.
-
- EfiPciHostBridgeEndBusAllocation The bus allocation and bus programming
- phase is complete. No specific action
- is required here. This notification
- can be used to perform any
- chipset-specific programming.
-
- EfiPciHostBridgeBeginResourceAllocation
- The resource allocation phase is about
- to begin. No specific action is
- required here. This notification can
- be used to perform any
- chipset-specific programming.
-
- EfiPciHostBridgeAllocateResources Allocates resources per previously
- submitted requests for all the PCI
- root bridges. These resource settings
- are returned on the next call to
- GetProposedResources(). Before calling
- NotifyPhase() with a Phase of
- EfiPciHostBridgeAllocateResource, the
- PCI bus enumerator is responsible for
- gathering I/O and memory requests for
- all the PCI root bridges and
- submitting these requests using
- SubmitResources(). This function pads
- the resource amount to suit the root
- bridge hardware, takes care of
- dependencies between the PCI root
- bridges, and calls the Global
- Coherency Domain (GCD) with the
- allocation request. In the case of
- padding, the allocated range could be
- bigger than what was requested.
-
- EfiPciHostBridgeSetResources Programs the host bridge hardware to
- decode previously allocated resources
- (proposed resources) for all the PCI
- root bridges. After the hardware is
- programmed, reassigning resources will
- not be supported. The bus settings are
- not affected.
-
- EfiPciHostBridgeFreeResources Deallocates resources that were
- previously allocated for all the PCI
- root bridges and resets the I/O and
- memory apertures to their initial
- state. The bus settings are not
- affected. If the request to allocate
- resources fails, the PCI enumerator
- can use this notification to
- deallocate previous resources, adjust
- the requests, and retry allocation.
-
- EfiPciHostBridgeEndResourceAllocation The resource allocation phase is
- completed. No specific action is
- required here. This notification can
- be used to perform any chipsetspecific
- programming.
-
- @param[in] This The instance pointer of
- EFI_PCI_HOST_BRIDGE_RESOURCE_ALLOCATION_PROTOCOL
-
- @param[in] Phase The phase during enumeration
-
- @retval EFI_NOT_READY This phase cannot be entered at this time. For
- example, this error is valid for a Phase of
- EfiPciHostBridgeAllocateResources if
- SubmitResources() has not been called for one
- or more PCI root bridges before this call
-
- @retval EFI_DEVICE_ERROR Programming failed due to a hardware error.
- This error is valid for a Phase of
- EfiPciHostBridgeSetResources.
-
- @retval EFI_INVALID_PARAMETER Invalid phase parameter
-
- @retval EFI_OUT_OF_RESOURCES The request could not be completed due to a
- lack of resources. This error is valid for a
- Phase of EfiPciHostBridgeAllocateResources if
- the previously submitted resource requests
- cannot be fulfilled or were only partially
- fulfilled.
-
- @retval EFI_SUCCESS The notification was accepted without any
- errors.

- Returns the allocation attributes of a PCI root bridge.
-
- The function returns the allocation attributes of a specific PCI root bridge.
- The attributes can vary from one PCI root bridge to another. These attributes
- are different from the decode-related attributes that are returned by the
- EFI_PCI_ROOT_BRIDGE_IO_PROTOCOL.GetAttributes() member function. The
- RootBridgeHandle parameter is used to specify the instance of the PCI root
- bridge. The device handles of all the root bridges that are associated with
- this host bridge must be obtained by calling GetNextRootBridge(). The
- attributes are static in the sense that they do not change during or after
- the enumeration process. The hardware may provide mechanisms to change the
- attributes on the fly, but such changes must be completed before
- EFI_PCI_HOST_BRIDGE_RESOURCE_ALLOCATION_PROTOCOL is installed. The permitted
- values of EFI_PCI_HOST_BRIDGE_RESOURCE_ALLOCATION_ATTRIBUTES are defined in
- "Related Definitions" below. The caller uses these attributes to combine
- multiple resource requests.
-
- For example, if the flag EFI_PCI_HOST_BRIDGE_COMBINE_MEM_PMEM is set, the PCI
- bus enumerator needs to include requests for the prefetchable memory in the
- nonprefetchable memory pool and not request any prefetchable memory.
-

- ------------------------------------ ---------------------------------------
- EFI_PCI_HOST_BRIDGE_COMBINE_MEM_PMEM If this bit is set, then the PCI root
- bridge does not support separate

- prefetchable memory. A PCI bus driver
- needs to include requests for
- prefetchable memory in the
- nonprefetchable memory pool.
-
- EFI_PCI_HOST_BRIDGE_MEM64_DECODE If this bit is set, then the PCI root
- bridge supports 64-bit memory windows.
- If this bit is not set, the PCI bus

- These are the notifications from the PCI bus driver that it is about to enter
- a certain phase of the PCI enumeration process.
-
- This member function can be used to notify the host bridge driver to perform
- specific actions, including any chipset-specific initialization, so that the
- chipset is ready to enter the next phase. Eight notification points are
- defined at this time. See belows:
-
- EfiPciHostBridgeBeginEnumeration Resets the host bridge PCI apertures
- and internal data structures. The PCI
- enumerator should issue this
- notification before starting a fresh
- enumeration process. Enumeration
- cannot be restarted after sending any
- other notification such as
- EfiPciHostBridgeBeginBusAllocation.
-
- EfiPciHostBridgeBeginBusAllocation The bus allocation phase is about to
- begin. No specific action is required
- here. This notification can be used to
- perform any chipset-specific
- programming.
-
- EfiPciHostBridgeEndBusAllocation The bus allocation and bus programming
- phase is complete. No specific action
- is required here. This notification
- can be used to perform any
- chipset-specific programming.
-
- EfiPciHostBridgeBeginResourceAllocation
- The resource allocation phase is about
- to begin. No specific action is
- required here. This notification can
- be used to perform any
- chipset-specific programming.
-
- EfiPciHostBridgeAllocateResources Allocates resources per previously
- submitted requests for all the PCI
- root bridges. These resource settings
- are returned on the next call to
- GetProposedResources(). Before calling
- NotifyPhase() with a Phase of
- EfiPciHostBridgeAllocateResource, the
- PCI bus enumerator is responsible for
- gathering I/O and memory requests for
- all the PCI root bridges and
- submitting these requests using
- SubmitResources(). This function pads
- the resource amount to suit the root
- bridge hardware, takes care of
- dependencies between the PCI root
- bridges, and calls the Global
- Coherency Domain (GCD) with the
- allocation request. In the case of
- padding, the allocated range could be
- bigger than what was requested.
-
- EfiPciHostBridgeSetResources Programs the host bridge hardware to
- decode previously allocated resources
- (proposed resources) for all the PCI
- root bridges. After the hardware is
- programmed, reassigning resources will
- not be supported. The bus settings are
- not affected.
-
- EfiPciHostBridgeFreeResources Deallocates resources that were
- previously allocated for all the PCI
- root bridges and resets the I/O and
- memory apertures to their initial
- state. The bus settings are not
- affected. If the request to allocate
- resources fails, the PCI enumerator
- can use this notification to
- deallocate previous resources, adjust
- the requests, and retry allocation.
-
- EfiPciHostBridgeEndResourceAllocation The resource allocation phase is
- completed. No specific action is
- required here. This notification can
- be used to perform any chipsetspecific
- programming.
-
- @param[in] This The instance pointer of
- EFI_PCI_HOST_BRIDGE_RESOURCE_ALLOCATION_PROTOCOL
-
- @param[in] Phase The phase during enumeration
-
- @retval EFI_NOT_READY This phase cannot be entered at this time. For

- EfiPciHostBridgeAllocateResources if
- SubmitResources() has not been called for one

-
- @retval EFI_DEVICE_ERROR Programming failed due to a hardware error.
- This error is valid for a Phase of
- EfiPciHostBridgeSetResources.
-
- @retval EFI_INVALID_PARAMETER Invalid phase parameter
-
- @retval EFI_OUT_OF_RESOURCES The request could not be completed due to a
- lack of resources. This error is valid for a
- Phase of EfiPciHostBridgeAllocateResources if

- Returns the allocation attributes of a PCI root bridge.
-
- The function returns the allocation attributes of a specific PCI root bridge.
- The attributes can vary from one PCI root bridge to another. These attributes
- are different from the decode-related attributes that are returned by the
- EFI_PCI_ROOT_BRIDGE_IO_PROTOCOL.GetAttributes() member function. The
- RootBridgeHandle parameter is used to specify the instance of the PCI root
- bridge. The device handles of all the root bridges that are associated with
- this host bridge must be obtained by calling GetNextRootBridge(). The
- attributes are static in the sense that they do not change during or after
- the enumeration process. The hardware may provide mechanisms to change the
- attributes on the fly, but such changes must be completed before
- EFI_PCI_HOST_BRIDGE_RESOURCE_ALLOCATION_PROTOCOL is installed. The permitted
- values of EFI_PCI_HOST_BRIDGE_RESOURCE_ALLOCATION_ATTRIBUTES are defined in
- "Related Definitions" below. The caller uses these attributes to combine
- multiple resource requests.
-
- For example, if the flag EFI_PCI_HOST_BRIDGE_COMBINE_MEM_PMEM is set, the PCI
- bus enumerator needs to include requests for the prefetchable memory in the
- nonprefetchable memory pool and not request any prefetchable memory.
-
- Attribute Description
- ------------------------------------ ---------------------------------------
- EFI_PCI_HOST_BRIDGE_COMBINE_MEM_PMEM If this bit is set, then the PCI root
- bridge does not support separate
- windows for nonprefetchable and
- prefetchable memory. A PCI bus driver
- needs to include requests for
- prefetchable memory in the
- nonprefetchable memory pool.
-
- EFI_PCI_HOST_BRIDGE_MEM64_DECODE If this bit is set, then the PCI root
- bridge supports 64-bit memory windows.
- If this bit is not set, the PCI bus
- driver needs to include requests for a
- 64-bit memory address in the
- corresponding 32-bit memory pool.
-
- @param[in] This The instance pointer of
- EFI_PCI_HOST_BRIDGE_RESOURCE_ALLOCATION_PROTOCOL
-
- @param[in] RootBridgeHandle The device handle of the PCI root bridge in
- which the caller is interested. Type
- EFI_HANDLE is defined in

-// The HiiAddPackages() library function requires that any controller (or
-// image) handle, to be associated with the HII packages under installation, be
-// "decorated" with a device path. The tradition seems to be a vendor device
-// path.
-//
-// We'd like to associate our HII packages with the driver's image handle. The
-// first idea is to use the driver image's device path. Unfortunately, loaded
-// images only come with an EFI_LOADED_IMAGE_DEVICE_PATH_PROTOCOL (not the
-// usual EFI_DEVICE_PATH_PROTOCOL), ie. a different GUID. In addition, even the
-// EFI_LOADED_IMAGE_DEVICE_PATH_PROTOCOL interface may be NULL, if the image
-// has been loaded from an "unnamed" memory source buffer.
-//
-// Hence let's just stick with the tradition -- use a dedicated vendor device
-// path, with the driver's FILE_GUID.

- managing the controller specified by ControllerHandle and ChildHandle,
- then EFI_UNSUPPORTED is returned. If the driver specified by This does not
- support the language specified by Language, then EFI_UNSUPPORTED is returned.
-
- @param This[in] A pointer to the EFI_COMPONENT_NAME2_PROTOCOL or
- EFI_COMPONENT_NAME_PROTOCOL instance.
-
- @param ControllerHandle[in] The handle of a controller that the driver
- specified by This is managing. This handle
- specifies the controller whose name is to be
- returned.

- the name of. This is an optional parameter that
- may be NULL. It will be NULL for device
- drivers. It will also be NULL for a bus drivers
- that wish to retrieve the name of the bus
- controller. It will not be NULL for a bus
- driver that wishes to retrieve the name of a
- child controller.
-
- @param Language[in] A pointer to a Null-terminated ASCII string
- array indicating the language. This is the
- language of the driver name that the caller is
- requesting, and it must match one of the
- languages specified in SupportedLanguages. The
- number of languages supported by a driver is up
- to the driver writer. Language is specified in
- RFC 4646 or ISO 639-2 language code format.
-
- @param ControllerName[out] A pointer to the Unicode string to return.
- This Unicode string is the name of the
- controller specified by ControllerHandle and
- ChildHandle in the language specified by

-=== OVMF OVERVIEW ===
-
-The Open Virtual Machine Firmware (OVMF) project aims
-to support firmware for Virtual Machines using the edk2
-code base. More information can be found at:
-
-http://www.tianocore.org/ovmf/
-
-=== STATUS ===
-
-Current capabilities:
-* IA32 and X64 architectures
-* QEMU (0.10.0 or later)
- - Video, keyboard, IDE, CD-ROM, serial
- - Runs UEFI shell
- - Optional NIC support. Requires QEMU (0.12.2 or later)
-* UEFI Linux boots
-* UEFI Windows 8 boots
-* UEFI Windows 7 & Windows 2008 Server boot (see important notes below!)
-
-=== FUTURE PLANS ===
-
-* Test/Stabilize UEFI Self-Certification Tests (SCT) results
-
-=== BUILDING OVMF ===
-
-Pre-requisites:
-* Build environment capable of build the edk2 MdeModulePkg.
-* A properly configured ASL compiler:
- - Intel ASL compiler: Available from http://www.acpica.org
- - Microsoft ASL compiler: Available from http://www.acpi.info
-* NASM: http://www.nasm.us/
-
-Update Conf/target.txt ACTIVE_PLATFORM for OVMF:
- PEI arch DXE arch UEFI interfaces
-* OvmfPkg/OvmfPkgIa32.dsc IA32 IA32 IA32
-* OvmfPkg/OvmfPkgIa32X64.dsc IA32 X64 X64
-* OvmfPkg/OvmfPkgX64.dsc X64 X64 X64
-
-Update Conf/target.txt TARGET_ARCH based on the .dsc file:
- TARGET_ARCH
-* OvmfPkg/OvmfPkgIa32.dsc IA32
-* OvmfPkg/OvmfPkgIa32X64.dsc IA32 X64
-* OvmfPkg/OvmfPkgX64.dsc X64
-
-Following the edk2 build process, you will find the OVMF binaries
-under the $WORKSPACE/Build/*/*/FV directory. The actual path will
-depend on how your build is configured. You can expect to find
-these binary outputs:
-* OVMF.FD
- - Please note! This filename has changed. Older releases used OVMF.Fv.
-* OvmfVideo.rom
- - This file is not built separately any longer, starting with svn r13520.
-
-More information on building OVMF can be found at:
-
-https://github.com/tianocore/tianocore.github.io/wiki/How%20to%20build%20OVMF
-
-=== RUNNING OVMF on QEMU ===
-
-* QEMU 0.12.2 or later is required.
-* Be sure to use qemu-system-x86_64, if you are using and X64 firmware.
- (qemu-system-x86_64 works for the IA32 firmware as well, of course.)
-* Use OVMF for QEMU firmware (3 options available)
- - Option 1: QEMU 1.6 or newer; Use QEMU -pflash parameter
- * QEMU/OVMF will use emulated flash, and fully support UEFI variables
- * Run qemu with: -pflash path/to/OVMF.fd
- * Note that this option is required for running SecureBoot-enabled builds
- (-D SECURE_BOOT_ENABLE).
- - Option 2: Use QEMU -bios parameter
- * Note that UEFI variables will be partially emulated, and non-volatile
- variables may lose their contents after a reboot
- * Run qemu with: -bios path/to/OVMF.fd
- - Option 3: Use QEMU -L parameter
- * Note that UEFI variables will be partially emulated, and non-volatile
- variables may lose their contents after a reboot
- * Either copy, rename or symlink OVMF.fd => bios.bin
- * Use the QEMU -L parameter to specify the directory where the bios.bin
- file is located.
-* The EFI shell is built into OVMF builds at this time, so it should
- run automatically if a UEFI boot application is not found on the
- removable media.
-* On Linux, newer version of QEMU may enable KVM feature, and this might
- cause OVMF to fail to boot. The QEMU '-no-kvm' may allow OVMF to boot.
-* Capturing OVMF debug messages on qemu:
- - The default OVMF build writes debug messages to IO port 0x402. The
- following qemu command line options save them in the file called
- debug.log: '-debugcon file:debug.log -global isa-debugcon.iobase=0x402'.
- - It is possible to revert to the original behavior, when debug messages were
- written to the emulated serial port (potentially intermixing OVMF debug
- output with UEFI serial console output). For this the
- '-D DEBUG_ON_SERIAL_PORT' option has to be passed to the build command (see
- the next section), and in order to capture the serial output qemu needs to
- be started with eg. '-serial file:serial.log'.
- - Debug messages fall into several categories. Logged vs. suppressed
- categories are controlled at OVMF build time by the
- 'gEfiMdePkgTokenSpaceGuid.PcdDebugPrintErrorLevel' bitmask (an UINT32
- value) in the selected .dsc file. Individual bits of this bitmask are
- defined in <MdePkg/Include/Library/DebugLib.h>. One non-default bit (with
- some performance impact) that is frequently set for debugging is 0x00400000
- (DEBUG_VERBOSE).
- - The RELEASE build target ('-b RELEASE' build option, see below) disables
- all debug messages. The default build target is DEBUG.
-
-=== Build Scripts ===
-
-On systems with the bash shell you can use OvmfPkg/build.sh to simplify
-building and running OVMF.
-
-So, for example, to build + run OVMF X64:
-$ OvmfPkg/build.sh -a X64
-$ OvmfPkg/build.sh -a X64 qemu
-
-And to run a 64-bit UEFI bootable ISO image:
-$ OvmfPkg/build.sh -a X64 qemu -cdrom /path/to/disk-image.iso
-
-To build a 32-bit OVMF without debug messages using GCC 4.5:
-$ OvmfPkg/build.sh -a IA32 -b RELEASE -t GCC45
-
-=== Network Support ===
-
-OVMF provides a UEFI network stack by default. Its lowest level driver is the
-NIC driver, higher levels are generic. In order to make DHCP, PXE Boot, and eg.
-socket test utilities from the StdLib edk2 package work, (1) qemu has to be
-configured to emulate a NIC, (2) a matching UEFI NIC driver must be available
-when OVMF boots.
-
-(If a NIC is configured for the virtual machine, and -- dependent on boot order
--- PXE booting is attempted, but no DHCP server responds to OVMF's DHCP
-DISCOVER message at startup, the boot process may take approx. 3 seconds
-longer.)
-
-* For each NIC emulated by qemu, a GPLv2 licensed UEFI driver is available from
- the iPXE project. The qemu source distribution, starting with version 1.5,
- contains prebuilt binaries of these drivers (and of course allows one to
- rebuild them from source as well). This is the recommended set of drivers.
-
-* Use the qemu -netdev and -device options, or the legacy -net option, to
- enable NIC support: <http://wiki.qemu.org/Documentation/Networking>.
-
-* For a qemu >= 1.5 binary running *without* any "-M machine" option where
- "machine" would identify a < qemu-1.5 configuration (for example: "-M
- pc-i440fx-1.4" or "-M pc-0.13"), the iPXE drivers are automatically available
- to and configured for OVMF in the default qemu installation.
-
-* For a qemu binary in [0.13, 1.5), or a qemu >= 1.5 binary with an "-M
- machine" option where "machine" selects a < qemu-1.5 configuration:
-
- - download a >= 1.5.0-rc1 source tarball from <http://wiki.qemu.org/Download>,
-
- - extract the following iPXE driver files from the tarball and install them
- in a location that is accessible to qemu processes (this may depend on your
- SELinux configuration, for example):
-
- qemu-VERSION/pc-bios/efi-e1000.rom
- qemu-VERSION/pc-bios/efi-ne2k_pci.rom
- qemu-VERSION/pc-bios/efi-pcnet.rom
- qemu-VERSION/pc-bios/efi-rtl8139.rom
- qemu-VERSION/pc-bios/efi-virtio.rom
-
- - extend the NIC's -device option on the qemu command line with a matching
- "romfile=" optarg:
-
- -device e1000,...,romfile=/full/path/to/efi-e1000.rom
- -device ne2k_pci,...,romfile=/full/path/to/efi-ne2k_pci.rom
- -device pcnet,...,romfile=/full/path/to/efi-pcnet.rom
- -device rtl8139,...,romfile=/full/path/to/efi-rtl8139.rom
- -device virtio-net-pci,...,romfile=/full/path/to/efi-virtio.rom
-
-* Independently of the iPXE NIC drivers, the default OVMF build provides a
- basic virtio-net driver, located in OvmfPkg/VirtioNetDxe.
-
-* Also independently of the iPXE NIC drivers, Intel's proprietary E1000 NIC
- driver (PROEFI) can be embedded in the OVMF image at build time:
-
- - Download UEFI drivers for the e1000 NIC
- - http://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&DwnldID=17515&lang=eng
- - Install the drivers into a directory called Intel3.5 in your WORKSPACE.
-
- - Include the driver in OVMF during the build:
- - Add "-D E1000_ENABLE -D FD_SIZE_2MB" to your build command,
- - For example: "build -D E1000_ENABLE -D FD_SIZE_2MB".
-
-* When a matching iPXE driver is configured for a NIC as described above, it
- takes priority over other drivers that could possibly drive the card too:
-
- | e1000 ne2k_pci pcnet rtl8139 virtio-net-pci
- -------------+------------------------------------------------
- iPXE | x x x x x
- VirtioNetDxe | x
- Intel PROEFI | x
-
-=== OVMF Flash Layout ===
-
-Like all current IA32/X64 system designs, OVMF's firmware
-device (rom/flash) appears in QEMU's physical address space
-just below 4GB (0x100000000).
-
-The layout of the firmware device in memory looks like:
-
-+--------------------------------------- 4GB (0x100000000)
-| VTF0 (16-bit reset code) and OVMF SEC
-| (SECFV)
-+--------------------------------------- varies based on flash size
-|
-| Compressed main firmware image
-| (FVMAIN_COMPACT)
-|
-+--------------------------------------- base + 0x20000
-| Fault-tolerant write (FTW)
-| Spare blocks (64KB/0x10000)
-+--------------------------------------- base + 0x10000
-| FTW Work block (4KB/0x1000)
-+--------------------------------------- base + 0x0f000
-| Event log area (4KB/0x1000)
-+--------------------------------------- base + 0x0e000
-| Non-volatile variable storage
-| area (56KB/0xe000)
-+--------------------------------------- base address
-
-OVMF supports building a 1MB or a 2MB flash image. The base address for
-a 1MB image in QEMU physical memory is 0xfff00000. The base address for
-a 2MB image is 0xffe00000.
-
-The code in SECFV locates FVMAIN_COMPACT, and decompresses the
-main firmware (MAINFV) into RAM memory at address 0x800000. The
-remaining OVMF firmware then uses this decompressed firmware
-volume image.
-
-=== UNIXGCC Debug ===
-
-If you build with the UNIXGCC toolchain, then debugging will be disabled
-due to larger image sizes being produced by the UNIXGCC toolchain. The
-first choice recommendation is to use GCC44 or newer instead.
-
-If you must use UNIXGCC, then you can override the build options for
-particular libraries and modules in the .dsc to re-enable debugging
-selectively. For example:
- [Components]
- OvmfPkg/Library/PlatformBdsLib/PlatformBdsLib.inf {
- <BuildOptions>
- GCC:*_*_*_CC_FLAGS = -UMDEPKG_NDEBUG
- }
- IntelFrameworkModulePkg/Universal/BdsDxe/BdsDxe.inf {
- <BuildOptions>
- GCC:*_*_*_CC_FLAGS = -UMDEPKG_NDEBUG
- }
-
-=== UEFI Windows 7 & Windows 2008 Server ===
-
-* One of the '-vga std' and '-vga qxl' QEMU options should be used.
-* Only one video mode, 1024x768x32, is supported at OS runtime.
-* The '-vga qxl' QEMU option is recommended. After booting the installed
- guest OS, select the video card in Device Manager, and upgrade its driver
- to the QXL XDDM one. Download location:
- <http://www.spice-space.org/download.html>, Guest | Windows binaries.
- This enables further resolutions at OS runtime, and provides S3
- (suspend/resume) capability.

- Format a read / write / flush request as three consecutive virtio

- been verified by
- - specific checks in ReadBlocks() / WriteBlocks() / FlushBlocks(), and
- - VerifyReadWriteRequest() (for read/write only).
-
- Parameters handled commonly:
-
- @param[in] Dev The virtio-blk device the request is targeted
- at.
-
- Flush request:
-
- @param[in] Lba Must be zero.
-
- @param[in] BufferSize Must be zero.
-
- @param[in out] Buffer Ignored by the function.
-
- @param[in] RequestIsWrite Must be TRUE.
-
- Read/Write request:
-
- @param[in] Lba Logical Block Address: number of logical blocks
- to skip from the beginning of the device.
-
- @param[in] BufferSize Size of buffer to transfer, in bytes. The caller
- is responsible to ensure this parameter is
- positive.
-
- @param[in out] Buffer The guest side area to read data from the device
- into, or write data to the device from.
-
- @param[in] RequestIsWrite TRUE iff data transfer goes from guest to
- device.
-
- Return values are common to both use cases, and are appropriate to be
- forwarded by the EFI_BLOCK_IO_PROTOCOL functions (ReadBlocks(),

- @retval EFI_SUCCESS Transfer complete.

- Stops a device controller or a bus controller.
-
- The Stop() function is designed to be invoked from the EFI boot service
- DisconnectController(). As a result, much of the error checking on the
- parameters to Stop() has been moved into this common boot service. It is
- legal to call Stop() from other locations, but the following calling
- restrictions must be followed, or the system behavior will not be
- deterministic.
- 1. ControllerHandle must be a valid EFI_HANDLE that was used on a previous
- call to this same driver's Start() function.
- 2. The first NumberOfChildren handles of ChildHandleBuffer must all be a
- valid EFI_HANDLE. In addition, all of these handles must have been created
- in this driver's Start() function, and the Start() function must have
- called OpenProtocol() on ControllerHandle with an Attribute of
- EFI_OPEN_PROTOCOL_BY_CHILD_CONTROLLER.
-
- @param[in] This A pointer to the EFI_DRIVER_BINDING_PROTOCOL
- instance.
- @param[in] ControllerHandle A handle to the device being stopped. The
- handle must support a bus specific I/O
- protocol for the driver to use to stop the
- device.
- @param[in] NumberOfChildren The number of child device handles in
- ChildHandleBuffer.
- @param[in] ChildHandleBuffer An array of child handles to be freed. May be
- NULL if NumberOfChildren is 0.

-Summary
--------
-
-The VirtioNetDxe UEFI_DRIVER implements the Simple Network Protocol for
-virtio-net devices. Higher level protocols are automatically installed on top
-of it by the DXE Core / the ConnectController() boot service, enabling for
-virtio-net devices eg. DHCP configuration, TCP transfers with edk2 StdLib
-applications, and PXE booting in OVMF.
-
-
-UEFI driver structure
----------------------
-
-A driver instance, belonging to a given virtio-net device, can be in one of
-four states at any time. The states stack up as follows below. The state
-transitions are labeled with the primary function (and its important callees
-faithfully indented) that implement the transition.
-
- | ^
- | |
- [DriverBinding.c] | | [DriverBinding.c]
- VirtioNetDriverBindingStart | | VirtioNetDriverBindingStop
- VirtioNetSnpPopulate | | VirtioNetSnpEvacuate
- VirtioNetGetFeatures | |
- v |
- +-------------------------+
- | EfiSimpleNetworkStopped |
- +-------------------------+
- | ^
- [SnpStart.c] | | [SnpStop.c]
- VirtioNetStart | | VirtioNetStop
- | |
- v |
- +-------------------------+
- | EfiSimpleNetworkStarted |
- +-------------------------+
- | ^
- [SnpInitialize.c] | | [SnpShutdown.c]
- VirtioNetInitialize | | VirtioNetShutdown
- VirtioNetInitRing {Rx, Tx} | | VirtioNetShutdownRx [SnpSharedHelpers.c]
- VirtioRingInit | | VirtioNetShutdownTx [SnpSharedHelpers.c]
- VirtioNetInitTx | | VirtioRingUninit {Tx, Rx}
- VirtioNetInitRx | |
- v |
- +-----------------------------+
- | EfiSimpleNetworkInitialized |
- +-----------------------------+
-
-The state at the top means "nonexistent" and is hence unnamed on the diagram --
-a driver instance actually doesn't exist at that point. The transition
-functions out of and into that state implement the Driver Binding Protocol.
-
-The lower three states characterize an existent driver instance and are all
-states defined by the Simple Network Protocol. The transition functions between
-them are member functions of the Simple Network Protocol.
-
-Each transition function validates its expected source state and its
-parameters. For example, VirtioNetDriverBindingStop will refuse to disconnect
-from the controller unless it's in EfiSimpleNetworkStopped.
-
-
-Driver instance states (Simple Network Protocol)
-------------------------------------------------
-
-In the EfiSimpleNetworkStopped state, the virtio-net device is (has been)
-re-set. No resources are allocated for networking / traffic purposes. The MAC
-address and other device attributes have been retrieved from the device (this
-is necessary for completing the VirtioNetDriverBindingStart transition).
-
-The EfiSimpleNetworkStarted is completely identical to the
-EfiSimpleNetworkStopped state for virtio-net, in the functional and
-resource-usage sense. This state is mandated / provided by the Simple Network
-Protocol for flexibility that the virtio-net driver doesn't exploit.
-
-In particular, the EfiSimpleNetworkStarted state is the target of the Shutdown
-SNP member function, and must therefore correspond to a hardware configuration
-where "[it] is safe for another driver to initialize". (Clearly another UEFI
-driver could not do that due to the exclusivity of the driver binding that
-VirtioNetDriverBindingStart() installs, but a later OS driver might qualify.)
-
-The EfiSimpleNetworkInitialized state is the live state of the virtio NIC / the
-driver instance. Virtio and other resources required for network traffic have
-been allocated, and the following SNP member functions are available (in
-addition to VirtioNetShutdown which leaves the state):
-
-- VirtioNetReceive [SnpReceive.c]: poll the virtio NIC for an Rx packet that
- may have arrived asynchronously;
-
-- VirtioNetTransmit [SnpTransmit.c]: queue a Tx packet for asynchronous
- transmission (meant to be used together with VirtioNetGetStatus);
-
-- VirtioNetGetStatus [SnpGetStatus.c]: query link status and status of pending
- Tx packets;
-
-- VirtioNetMcastIpToMac [SnpMcastIpToMac.c]: transform a multicast IPv4/IPv6
- address into a multicast MAC address;
-
-- VirtioNetReceiveFilters [SnpReceiveFilters.c]: emulate unicast / multicast /
- broadcast filter configuration (not their actual effect -- a more liberal
- filter setting than requested is allowed by the UEFI specification).
-
-The following SNP member functions are not supported [SnpUnsupported.c]:
-
-- VirtioNetReset: reinitialize the virtio NIC without shutting it down (a loop
- from/to EfiSimpleNetworkInitialized);
-
-- VirtioNetStationAddress: assign a new MAC address to the virtio NIC,
-
-- VirtioNetStatistics: collect statistics,
-
-- VirtioNetNvData: access non-volatile data on the virtio NIC.
-
-Missing support for these functions is allowed by the UEFI specification and
-doesn't seem to trip up higher level protocols.
-
-
-Events and task priority levels
--------------------------------
-
-The UEFI specification defines a sophisticated mechanism for asynchronous
-events / callbacks (see "6.1 Event, Timer, and Task Priority Services" for
-details). Such callbacks work like software interrupts, and some notion of
-locking / masking is important to implement critical sections (atomic or
-exclusive access to data or a device). This notion is defined as Task Priority
-Levels.
-
-The virtio-net driver for OVMF must concern itself with events for two reasons:
-
-- The Simple Network Protocol provides its clients with a (non-optional) WAIT
- type event called WaitForPacket: it allows them to check or wait for Rx
- packets by polling or blocking on this event. (This functionality overlaps
- with the Receive member function.) The event is available to clients starting
- with EfiSimpleNetworkStopped (inclusive).
-
- The virtio-net driver is informed about such client polling or blockage by
- receiving an asynchronous callback (a software interrupt). In the callback
- function the driver must interrogate the driver instance state, and if it is
- EfiSimpleNetworkInitialized, access the Rx queue and see if any packets are
- available for consumption. If so, it must signal the WaitForPacket WAIT type
- event, waking the client.
-
- For simplicity and safety, all parts of the virtio-net driver that access any
- bit of the driver instance (data or device) run at the TPL_CALLBACK level.
- This is the highest level allowed for an SNP implementation, and all code
- protected in this manner satisfies even stricter non-blocking requirements
- than what's documented for TPL_CALLBACK.
-
- The task priority level for the WaitForPacket callback too is set by the
- driver, the choice is TPL_CALLBACK again. This in effect serializes the
- WaitForPacket callback (VirtioNetIsPacketAvailable [Events.c]) with "normal"
- parts of the driver.
-
-- According to the Driver Writer's Guide, a network driver should install a
- callback function for the global EXIT_BOOT_SERVICES event (a special NOTIFY
- type event). When the ExitBootServices() boot service has cleaned up internal
- firmware state and is about to pass control to the OS, any network driver has
- to stop any in-flight DMA transfers, lest it corrupts OS memory. For this
- reason EXIT_BOOT_SERVICES is emitted and the network driver must abort
- in-flight DMA transfers.
-
- This callback (VirtioNetExitBoot) is synchronized with the rest of the driver
- code just the same as explained for WaitForPacket. In
- EfiSimpleNetworkInitialized state it resets the virtio NIC, halting all data
- transfer. After the callback returns, no further driver code is expected to
- be scheduled.
-
-
-Virtio internals -- Rx
-----------------------
-
-Requests (Rx and Tx alike) are always submitted by the guest and processed by
-the host. For Tx, processing means transmission. For Rx, processing means
-filling in the request with an incoming packet. Submitted requests exist on the
-"Available Ring", and answered (processed) requests show up on the "Used Ring".
-
-Packet data includes the media (Ethernet) header: destination MAC, source MAC,
-and Ethertype (14 bytes total).
-
-The following structures implement packet reception. Most of them are defined
-in the Virtio specification, the only driver-specific trait here is the static
-pre-configuration of the two-part descriptor chains, in VirtioNetInitRx. The
-diagram is simplified.
-
- Available Index Available Index
- last processed incremented
- by the host by the guest
- v -------> v

- =D4
-
-In VirtioNetInitRx, the guest allocates the fixed size Receive Destination
-Area, which accommodates all packets delivered asynchronously by the host. To
-each packet, a slice of this area is dedicated; each slice is further
-subdivided into virtio-net request header and network packet data. The
-(guest-physical) addresses of these sub-slices are denoted with A2, A3, A4 and
-so on. Importantly, an even-subscript "A" always belongs to a virtio-net
-request header, while an odd-subscript "A" always belongs to a packet
-sub-slice.
-
-Furthermore, the guest lays out a static pattern in the Descriptor Table. For
-each packet that can be in-flight or already arrived from the host,
-VirtioNetInitRx sets up a separate, two-part descriptor chain. For packet N,
-the Nth descriptor chain is set up as follows:
-
-- the first (=head) descriptor, with even index, points to the fixed-size
- sub-slice receiving the virtio-net request header,
-
-- the second descriptor (with odd index) points to the fixed (1514 byte) size
- sub-slice receiving the packet data,
-
-- a link from the first (head) descriptor in the chain is established to the
- second (tail) descriptor in the chain.
-
-Finally, the guest populates the Available Ring with the indices of the head
-descriptors. All descriptor indices on both the Available Ring and the Used
-Ring are even.
-
-Packet reception occurs as follows:
-
-- The host consumes a descriptor index off the Available Ring. This index is
- even (=2*N), and fingers the head descriptor of the chain belonging to packet
- N.
-
-- The host reads the descriptors D(2*N) and -- following the Next link there
- --- D(2*N+1), and stores the virtio-net request header at A(2*N), and the
- packet data at A(2*N+1).
-
-- The host places the index of the head descriptor, 2*N, onto the Used Ring,
- and sets the Len field in the same Used Ring Element to the total number of
- bytes transferred for the entire descriptor chain. This enables the guest to
- identify the length of Rx packets.
-
-- VirtioNetReceive polls the Used Ring. If a new Used Ring Element shows up, it
- copies the data out to the caller, and recycles the index of the head
- descriptor (ie. 2*N) to the Available Ring.
-
-- Because the host can process (answer) Rx requests in any order theoretically,
- the order of head descriptor indices on each of the Available Ring and the
- Used Ring is virtually random. (Except right after the initial population in
- VirtioNetInitRx, when the Available Ring is full and increasing, and the Used
- Ring is empty.)
-
-- If the Available Ring is empty, the host is forced to drop packets. If the
- Used Ring is empty, VirtioNetReceive returns EFI_NOT_READY (no packet
- available).
-
-
-Virtio internals -- Tx
-----------------------
-
-The transmission structure erected by VirtioNetInitTx is similar, it differs
-in the following:
-
-- There is no Receive Destination Area.
-
-- Each head descriptor, D(2*N), points to a read-only virtio-net request header
- that is shared by all of the head descriptors. This virtio-net request header
- is never modified by the host.
-
-- Each tail descriptor is re-pointed to the caller-supplied packet buffer
- whenever VirtioNetTransmit places the corresponding head descriptor on the
- Available Ring. The caller is responsible to hang on to the unmodified buffer
- until it is reported transmitted by VirtioNetGetStatus.
-
-Steps of packet transmission:
-
-- Client code calls VirtioNetTransmit. VirtioNetTransmit tracks free descriptor
- chains by keeping the indices of their head descriptors in a stack that is
- private to the driver instance. All elements of the stack are even.
-
-- If the stack is empty (that is, each descriptor chain, in isolation, is
- either pending transmission, or has been processed by the host but not
- yet recycled by a VirtioNetGetStatus call), then VirtioNetTransmit returns
- EFI_NOT_READY.
-
-- Otherwise the index of a free chain's head descriptor is popped from the
- stack. The linked tail descriptor is re-pointed as discussed above. The head
- descriptor's index is pushed on the Available Ring.
-
-- The host moves the head descriptor index from the Available Ring to the Used
- Ring when it transmits the packet.
-
-- Client code calls VirtioNetGetStatus. In case the Used Ring is empty, the
- function reports no Tx completion. Otherwise, a head descriptor's index is
- consumed from the Used Ring and recycled to the private stack. The client
- code's original packet buffer address is fetched from the tail descriptor
- (where it has been stored at VirtioNetTransmit time) and returned to the
- caller.
-
-- The Len field of the Used Ring Element is not checked. The host is assumed to
- have transmitted the entire packet -- VirtioNetTransmit had forced it below
- 1514 bytes (inclusive). The Virtio specification suggests this packet size is
- always accepted (and a lower MTU could be encountered on any later hop as
- well). Additionally, there's no good way to report a short transmit via
- VirtioNetGetStatus; EFI_DEVICE_ERROR seems too serious from the specification
- and higher level protocols could interpret it as a fatal condition.
-
-- The host can theoretically reorder head descriptor indices when moving them
- from the Available Ring to the Used Ring (out of order transmission). Because
- of this (and the choice of a stack over a list for free descriptor chain
- tracking) the order of head descriptor indices on either Ring is
- unpredictable.

- - No hotplug / hot-unplug.
-
- - Although EFI_EXT_SCSI_PASS_THRU_PROTOCOL.PassThru() could be a good match
- for multiple in-flight virtio-scsi requests, we stick to synchronous

-
- - Timeouts are not supported for EFI_EXT_SCSI_PASS_THRU_PROTOCOL.PassThru().
-
- - Only one channel is supported. (At the time of this writing, host-side
- virtio-scsi supports a single channel too.)
-
- - Only one request queue is used (for the one synchronous request).
-
- - The ResetChannel() and ResetTargetLun() functions of
- EFI_EXT_SCSI_PASS_THRU_PROTOCOL are not supported (which is allowed by the
- UEFI 2.3.1 Errata C specification), although
- VIRTIO_SCSI_T_TMF_LOGICAL_UNIT_RESET could be a good match. That would
- however require client code for the control queue, which is deemed
- unreasonable for now.

- Stops a bus controller.

- The Stop() function is designed to be invoked from the EFI boot service DisconnectController().

- into this common boot service. It is legal to call Stop() from other locations,
- but the following calling restrictions must be followed, or the system behavior will not be deterministic.
- 1. ControllerHandle must be a valid EFI_HANDLE that was used on a previous call to this
- same driver's Start() function.
- 2. The first NumberOfChildren handles of ChildHandleBuffer must all be a valid
- EFI_HANDLE. In addition, all of these handles must have been created in this driver's
- Start() function, and the Start() function must have called OpenProtocol() on
- ControllerHandle with an Attribute of EFI_OPEN_PROTOCOL_BY_CHILD_CONTROLLER.
-
- @param[in] This A pointer to the EFI_DRIVER_BINDING_PROTOCOL instance.
- @param[in] ControllerHandle A handle to the device being stopped. The handle must
- support a bus specific I/O protocol for the driver
- to use to stop the device.
- @param[in] NumberOfChildren The number of child device handles in ChildHandleBuffer.
- @param[in] ChildHandleBuffer An array of child handles to be freed. May be NULL
- if NumberOfChildren is 0.
-
- @retval EFI_SUCCESS The device was stopped.

- Low-level kernel interface to the XenStore.
-
- The XenStore interface is a simple storage system that is a means of
- communicating state and configuration data between the Xen Domain 0
- and the various guest domains. All configuration data other than
- a small amount of essential information required during the early
- boot process of launching a Xen aware guest, is managed using the
- XenStore.
-
- The XenStore is ASCII string based, and has a structure and semantics
- similar to a filesystem. There are files and directories, the directories
- able to contain files or other directories. The depth of the hierachy
- is only limited by the XenStore's maximum path length.
-
- The communication channel between the XenStore service and other
- domains is via two, guest specific, ring buffers in a shared memory
- area. One ring buffer is used for communicating in each direction.
- The grant table references for this shared memory are given to the
- guest either via the xen_start_info structure for a fully para-
- virtualized guest, or via HVM hypercalls for a hardware virtualized
- guest.
-
- The XenStore communication relies on an event channel and thus
- interrupts. But under OVMF this XenStore client will pull the
- state of the event channel.
-
- Several Xen services depend on the XenStore, most notably the
- XenBus used to discover and manage Xen devices.

- Tests to see if this driver supports a given controller. If a child device is provided,
- it further tests to see if this driver supports creating a handle for the specified child device.
-
- This function checks to see if the driver specified by This supports the device specified by
- ControllerHandle. Drivers will typically use the device path attached to
- ControllerHandle and/or the services from the bus I/O abstraction attached to
- ControllerHandle to determine if the driver supports ControllerHandle. This function
- may be called many times during platform initialization. In order to reduce boot times, the tests

- function must not change the state of any hardware devices, and this function must be aware that the
- device specified by ControllerHandle may already be managed by the same driver or a
- different driver. This function must match its calls to AllocatePages() with FreePages(),
- AllocatePool() with FreePool(), and OpenProtocol() with CloseProtocol().
- Because ControllerHandle may have been previously started by the same driver, if a protocol is
- already in the opened state, then it must not be closed with CloseProtocol(). This is required
- to guarantee the state of ControllerHandle is not modified by this function.

- @param[in] ControllerHandle The handle of the controller to test. This handle
- must support a protocol interface that supplies

- parameter is ignored by device drivers, and is optional for bus
- drivers. For bus drivers, if this parameter is not NULL, then
- the bus driver must determine if the bus controller specified
- by ControllerHandle and the child controller specified
- by RemainingDevicePath are both supported by this
- bus driver.
