OvmfPkg's file-based NvVar storage is read back as follows at boot (all
paths under OvmfPkg/Library/):
PlatformBdsPolicyBehavior() [PlatformBdsLib/BdsPlatform.c]
PlatformBdsRestoreNvVarsFromHardDisk()
VisitAllInstancesOfProtocol
for each simple file system:
VisitingFileSystemInstance()
ConnectNvVarsToFileSystem() [NvVarsFileLib/NvVarsFileLib.c]
LoadNvVarsFromFs() [NvVarsFileLib/FsAccess.c]
ReadNvVarsFile()
+-------------> SerializeVariablesSetSerializedVariables() [SerializeVariablesLib/SerializeVariablesLib.c]
| SerializeVariablesIterateInstanceVariables()
| +-------------> IterateVariablesInBuffer()
| | for each loaded / deserialized variable:
| +-|-----------------> IterateVariablesCallbackSetSystemVariable()
| | | gRT->SetVariable()
| | |
| | IterateVariablesInBuffer() stops processing variables as soon as the
| | first error is encountered from the callback function.
| |
| | In this case the callback function is
| IterateVariablesCallbackSetSystemVariable(), selected by
SerializeVariablesSetSerializedVariables().
The result is that no NvVar is restored from the file after the first
gRT->SetVariable() failure.
On my system such a failure
- never happens in an OVMF build with secure boot disabled,
- happens *immediately* with SECURE_BOOT_ENABLE, because the first
variable to restore is "AuthVarKeyDatabase".
"AuthVarKeyDatabase" has the EFI_VARIABLE_AUTHENTICATED_WRITE_ACCESS
attribute set. Since the loop tries to restore it before any keys (PK, KEK
etc) are enrolled, gRT->SetVariable() rejects it with
EFI_SECURITY_VIOLATION. Consequently the NvVar restore loop terminates
immediately, and we never reach non-authenticated variables such as
Boot#### and BootOrder.
Until work on KVM-compatible flash emulation converges between qemu and
OvmfPkg, improve the SECURE_BOOT_ENABLE boot experience by masking
EFI_SECURITY_VIOLATION in the callback:
- authenticated variables continue to be rejected same as before, but
- at least we allow the loop to progress and restore non-authenticated
variables, for example boot options.

Tested with the e1000, ne2k_pci, pcnet, rtl8139, and virtio iPXE UEFI
oprom drivers distributed with qemu-1.5.0-rc1. Also tested with Intel's

DHCP, PXE, and StdLib socket apps are enabled in OVMF by the sum of:
(a) a UEFI NIC driver,
(b) the generic network stack.
The only choice for (a) used to be the proprietary Intel E1000 driver,
which is cumbersome to obtain and enable.
The iPXE UEFI NIC drivers packaged with qemu-1.5 cover (a) for each NIC
type supported by qemu, and are easy to obtain & configure, even for
earlier qemu versions. Therefore enable (b) per default as well.
This doesn't take up much space; the binaries (b) adds to the firmware
don't seem to need -D FD_SIZE_2MB.
Intel's e1000 driver remains an option, requested by the -D E1000_ENABLE
build flag.

The descriptor table (also known as "queue") consists of descriptors. (The
corresponding type in the code is VRING_DESC.)
An individual descriptor describes a contiguous buffer, to be transferred
uni-directionally between host and guest.
Several descriptors in the descriptor table can be linked into a
descriptor chain, specifying a bi-directional scatter-gather transfer
between host and guest. Such a descriptor chain is also known as "virtio
request".
(The descriptor table can host sereval descriptor chains (in-flight virtio
requests) in parallel, but the OVMF driver supports at most one chain, at
any point in time.)
The first descriptor in any descriptor chain is called "head descriptor".
In order to submit a number of parallel requests (= a set of independent
descriptor chains) from the guest to the host, the guest must put *only*
the head descriptor of each separate chain onto the Available Ring.
VirtioLib currently places the head of its one descriptor chain onto the
Available Ring repeatedly, once for each single (head *or* dependent)
descriptor in said descriptor chain. If the descriptor chain comprises N
descriptors, this error amounts to submitting the same entire chain N
times in parallel.

On my Thinkpad T510 laptop with RHEL-6 as host, this probably leads to
simultaneous DMA transfers targeting the same RAM area. Even though the
source of each transfer is identical, the data is corrupted in the
destination buffer -- the CRC32 calculated over the buffer varies, even
though the origin of the transfers is the same, never rewritten LBA.

The problem is invisible on my HP Z400 workstation.
Fix the request submission by:
- building the only one descriptor chain supported by VirtioLib always at
the beginning of the descriptor table,
- ensuring the head descriptor of this chain is put on the Available Ring
only once,
- requesting the virtio spec's language to be cleaned up

Also, add a small delay after the 0xCF9 hard reset request -- on qemu/kvm the
port access is translated to the qemu-internal system reset request by the CPU
thread, and it might progress some more before the IO thread acts upon the
system reset request.
MicroSecondDelay() is implemented by OvmfPkg's own AcpiTimerLib.

The reset requested via the keyboard controller (port 0x64) is actually a
soft reset, but qemu has supported it since forever (plus qemu has not
distinguished between hard reset and soft reset, although this is changing
now). Therefore leave the current IoWrite() in place for compatibility.
On qemu versions with commit 1ec4ba74 ("PIIX3: reset the VM when the Reset
Control Register's RCPU bit gets set"), use the PIIX3 RCR as first choice.
In the future qemu will act differently on soft vs. hard reset requests,
and we should honor that in ResetCold().
Writing to ioport 0xCF9 on qemu builds prior to commit 1ec4ba74 should
have no effect. Access to the PCI host config register went through
several implementations in qemu. Commit 9f6f0423 ("pci_host: rewrite
using rwhandler") seems safe, both before and after.
Commit d0ed8076 ("pci_host: convert conf index and data ports to memory
API") inadvertently dropped the alignment/size check, causing a boot
regression on NetBSD. It was fixed about six months later in commit
cdde6ffc, which is current. Translating that to qemu releases, the bug
was visible from v1.0 to v1.1.0.
On physical hardware cycling between reset methods is sometimes necessary
<http://mjg59.dreamwidth.org/3561.html>. On qemu the port access should
trap immediately.

"MEMFD is built so MAINFV's contents will be relocated during the build to

Previously for IA32, we would only try to run qemu. Newer releases
of QEMU now have renamed the x86 qemu to qemu-system-i386.
Now, we search for:
1. qemu-system-i386
2. qemu-system-x86_64
3. qemu

The Xcode assembler is much pickier than GCC. Also the 64-bit
linker is not a fan of relocations so it is better to us IP
relative code, but at least it removes a relocation entry.

We're supposed to zero everything in the kernel bootparams that we don't
explicitly initialise, other than the setup_header from 0x1f1 onwards
for a precisely defined length, which is copied from the bzImage.
We're *not* supposed to just pass the garbage that we happened to find
in the bzImage file surrounding the setup_header.

We currently just jump to offset 0x200 in the kernel image, in 64-bit
mode. This is completely broken. If it's a 32-bit kernel, we'll be
jumping into the compressed data payload.
If it's a 64-bit kernel, it'll work... but the 0x200 offset is
explicitly marked as 'may change in the future', has already changed
from 0x100 to 0x200 in the past with no fanfare, and bootloaders are
instructed that they should look at the ELF header to find the offset.
So although it does actually work today, it's still broken in the
"someone needs to whipped for doing it this way" sense of the word.
In fact, the same bug exists in other bootloaders so the 0x200 offset
probably *is* now set in stone. But still it's only valid to use it if
we *know* it's a 64-bit kernel. And we don't. There *is* no ELF header
that we can look at when we're booting a bzImage, and we can't rely on
it having a PE/COFF header either.
The 32-bit entry point is always guaranteed to work, and we need to
support it anyway. So let's just *always* use it, in 32-bit mode, and
then we don't have to make up some horrible heuristics for detecting
32-bit vs. 64-bit kernels.

Move these states from the DSDT to the SSDT. Override the default
configuration if the host has the following qemu commit:
commit 459ae5ea5ad682c2b3220beb244d4102c1a4e332
Author: Gleb Natapov <gleb@redhat.com>
Date: Mon Jun 4 14:31:55 2012 +0300
Add PIIX4 properties to control PM system states.
This patch adds two things. First it allows QEMU to distinguish
between regular powerdown and S4 powerdown. Later separate QMP
notification will be added for S4 powerdown. Second it allows
S3/S4 states to be disabled from QEMU command line. Some guests
known to be broken with regards to power management, but allow to
use it anyway. Using new properties management will be able to
disable S3/S4 for such guests.
Supported system state are passed to a firmware using new fw_cfg
file. The file contains 6 byte array. Each byte represents one
system state. If byte at offset X has its MSB set it means that
system state X is supported and to enter it guest should use the
value from lowest 3 bits.

The ACPI 5.0 specification says:
7.3.4.4 System \_S3 State
[...]
* Dynamic RAM context is maintained.
[...]
This corresponds to the following in the PIIX4 spec:
PMCNTRL -- POWER MANAGEMENT CONTROL REGISTER (IO)
[...]
Bits[12:10] Suspend Type
[...]
001 STR (Suspend To RAM)
Also, this (ie. decimal 1) is the suspend type value that qemu recognizes
as an S3 (suspend to ram) request.
Only the value for PM1a_CNT.SLP_TYP is set (PM1b_CNT.SLP_TYP is left at
zero), since in OVMF we don't report the optional PM1b_EVT_BLK register
block to OSPM. (PM1b_EVT_BLK is defined as 0 in "Platform.h"; see "4.8.1.1
PM1 Event Registers" in the ACPI 5.0 specification.)
