2016-04-01ArmVirtPkg: disable PcdHiiOsRuntimeSupportLaszlo Ersek
Edk2 commit 8a45f80edad4 ("MdeModulePkg: Make HII configuration settings available to OS runtime") implements the optional UEFI feature described in "31.2.11.1 OS Runtime Utilization" in UEFI v2.6. While this feature might show benefits down the road even in QEMU virtual machines, at the moment it only presents drawbacks: - it increases the EfiRuntimeServicesData footprint, - it triggers HII compatibility problems between edk2 and external drivers unconditionally, even if the end-user is not interested in HII and/or in configuring said drivers (see <https://www.redhat.com/archives/vfio-users/2016-March/msg00153.html> and <http://thread.gmane.org/gmane.comp.bios.edk2.devel/9894> for an example). While the feature was being introduced, popular demand for a controlling Feature PCD rose (see <http://thread.gmane.org/gmane.comp.bios.edk2.devel/7626>), which is why we can set it now to FALSE.

2016-03-31ArmVirtPkg/ArmVirtQemu: gate FDT config table install with build optionArd Biesheuvel
This introduces the .DSC define 'PURE_ACPI_BOOT_ENABLE', defaulting to FALSE, which controls the value of the feature PCD 'PcdPureAcpiBoot'. This allows an ArmVirtQemu image to be built that restricts the OS to booting in ACPI mode. This feature is only added to ArmVirtQemu, and not to ArmVirtQemuKernel, the reason being that the latter is mostly intended for development work, where the burden of adding 'acpi=force' if you need it is much more tolerable than when trying to boot an installer on a production KVM guest instance.

2016-03-11ArmVirtPkg/VirtFdtDxe: set /chosen/linux,pci-probe-only to 1 in DTBArd Biesheuvel
Unlike Linux on x86, which typically honors the PCI configuration performed by the firmware, Linux on ARM assumes that the PCI subsystem needs to be configured from scratch. This is not entirely unreasonable given the historical background of embedded systems using very basic bootloaders, but is no longer tenable with Linux on arm64 moving to UEFI and ACPI in the server space. For this reason, PCI support in the arm64 kernel running under ACPI is likely to move to the x86 model of honoring the PCI configuration done by the firmware. So let's align with that in our DT based configuration as well, and set the /chosen/linux,pci-probe-only property to 1 in the Device Tree before we hand it to the OS. In case we are exposing an emulated VGA PCI device to the guest, which may subsequently get exposed via the Graphics Output protocol and driven as an efifb by the OS, this ensures the PCI resource allocations for the framebuffer are not overridden, since that would cause the framebuffer to stop working.

2016-02-18ArmVirtPkg: ArmVirtQemu: expose only 64-bit entry point for v3.0+ SMBIOSArd Biesheuvel
The legacy 32-bit SMBIOS entry point has little use on AARCH64 systems, since many such systems have no 32-bit addressable physical RAM, and so OSes that implement SMBIOS will have to be able to deal with the 64-bit entry point anyway. Given that the OS will map main memory in 1 GB chunks if it can, and that punching a page sized hole (e.g., for SMBIOS data) into it will result in the whole 1 GB chunk being mapped using 2 MB and 4 KB blocks instead, it is important to group memory reservations from the OS as much as we can, and allocating below 4 GB for no good reason interferes with that. This is especially important under virtualization, considering that each *level* of lookup at stage 1 (the guest virtual page table) will result in a full page table walk at stage 2 (the guest PA to host PA mapping). So expose only the 64-bit entry point when the SMBIOS tables adhere to version 3.0 or later.

2015-11-26ArmVirtPkg: Use SerialDxe in MdeModulePkg instead of EmbeddedPkgStar Zeng
Beyond just changing the directly related lines in the FDF and DSC files, we have to adapt the EarlyFdtPL011SerialPortLib and FdtPL011SerialPortLib instances as well, in the same patch. This is because the EmbeddedPkg driver expects the SerialPortSetAttributes(), SerialPortSetControl() and SerialPortGetControl() functions from SerialPortExtLib, while the MdeModulePkg driver expects them from SerialPortLib itself. We cannot implement these functions in ArmVirtPkg's SerialPortLib instances *before* flipping the driver, because it would cause double function definitions in the EmbeddedPkg driver. We also can't implement the functions *after* flipping the driver, because it would cause unresolved function references in the MdeModulePkg driver. Therefore we have to implement the functions simultaneously with the driver replacement.

2015-11-24ArmVirtPkg/ArmVirtPlatformLib: reduce ID map size to GCD region sizeArd Biesheuvel
The ID mapping routines on virtual platforms simply map the entire hardware supported physical address space as device memory, and then punch some holes for regions that need to be mapped cacheable. On virtual platforms hosted on CPUs that support a large physical address range, this may result in a lot of overhead, i.e., 4 KB of page tables for each 512 GB of address space, which quickly adds up (i.e., 2 MB for the architectural maximum of 48 bits). Since there may be a platform specific limit to the size of the (I)PA space that is not reflected by CPU id registers, restrict the range of the ID mapping to gEmbeddedTokenSpaceGuid.PcdPrePiCpuMemorySize bits. This makes sense by itself, since we cannot manipulate mappings above that limit anwyay (because they are not covered by GCD), and it allows the PCD be set to a lower value by platforms whose (I)PA space is smaller than the hardware supported maximum.

2015-11-18ArmVirtPkg/ArmVirtPlatformLib: map executable NOR region as normal memoryArd Biesheuvel
The ARM architecture version 7 and later mandates that device mappings have the XN (non-executable) bit set, to prevent speculative instruction fetches from read-sensitive regions. This implies that we should not map regions as device if we want to execute from them, so the NOR region that contains our FD image should be mapped as normal memory instead. The MMU code deals correctly with overlapping ARM_MEMORY_REGION_DESCRIPTOR entries, and later entries in the array take precedence over earlier ones. So simply add an entry to the end of the array that overrides the mapping attributes of the FD image, wherever it resides.

2015-09-25ArmVirtPkg: build the TFTP command into the UEFI shellLaszlo Ersek
The TFTP command is easy to use, it has very nice documentation (accessible with "HELP TFTP" in the shell), and it's a very versatile tool for downloading files from the host to the guest, via virtual network, while the guest is in the UEFI shell. Even better, enabling this command in the shell increases the uncompressed FVMAIN size only by 8192 bytes, in my AARCH64 build of VirtArmQemu.dsc, and the final size increase (after LZMA compression) that is visible in the FVMAIN_COMPACT volume is merely 1976 bytes.

2015-09-24ArmVirtPkg: VirtFdtDxe: detect fw-cfg DMA interface from the DTBLaszlo Ersek
A DMA-like transfer interface has recently been implemented in QEMU for fw-cfg. For ARM and AARCH64 virtual machines, the binding prescribes a new 8-byte wide register at offset 0x10 in the register block. Make VirtFdtDxe expose this register if it is present. Please see "docs/specs/fw_cfg.txt" in the QEMU tree for more information.

2015-09-22ArmVirtPkg: reduce preallocation of boot services data pagesArd Biesheuvel
Commit SVN r18503 ("MdeModulePkg DxeCore: Take the range in resource HOB for PHIT as higher priority") changed the GCD init logic to take the sum of the region sizes in gMemoryTypeInformation[] into account when estimating the minimal amount of memory needed to boot the system. Unfortunately, as an unintended side effect, this change results in boot failures of ArmVirtQemu when running with QEMU's default memory size of 128 MB. The reason is that the sum of the gMemoryTypeInformation region sizes plus the size of the inital PEI region exceeds 128 MB. Since we do not actually need to preallocate 20,000 pages' worth of BootServicesData memory, reduce this figure to the more reasonable 12,000.

2015-09-18ArmVirtPkg: PlatformIntelBdsLib: signal ReadyToBoot on direct kernel bootLaszlo Ersek
According to the UEFI spec, EFI_EVENT_GROUP_READY_TO_BOOT "is notified by the system when the Boot Manager is about to load and execute a boot option". ArmVirtPkg doesn't do this currently when launching a kernel from the QEMU command line. OvmfPkg does (see git commit 28a34033ee). At least two edk2-wide callbacks are worth mentioning: - OnReadyToBoot() in "MdeModulePkg/Universal/Variable/RuntimeDxe/VariableDxe.c" performs variable reclaim and (optionally) installs variable usage statistics as a vendor config table; - OnReadyToBoot() in "SecurityPkg/Library/DxeImageVerificationLib/DxeImageVerificationLib.c" installs the image execution info table if it doesn't exist yet, in SecureBoot-enabled builds.
