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.

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.
Available Ring Descriptor table

Anatomy of a single virtio-blk READ request (a descriptor chain with three
descriptors):
virtio-blk request header, prepared by guest:
VirtioAppendDesc PhysAddr=3FBC6050 Size=16 Flags=1 Head=1232 Next=1232
payload to be filled in by host:

host status, to be filled in by host:
VirtioAppendDesc PhysAddr=3FBC604F Size=1 Flags=2 Head=1232 Next=1234
Processing on the host side -- the descriptor chain is processed three
times in parallel (its head is available to virtqueue_pop() thrice); the
same chain is submitted/collected separately to/from AIO three times:

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.
SynchronousRequest Lba=585792 BufSiz=32768 ReqIsWrite=0 Crc32=BF68A44D
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.

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

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.

support the Debug Agent and the TimerLib is mapped into read-only ROM/FLASH.
The TimerLib in the OvmfPkg uses a global variable called mPmba and depends on that global being updated. This works for modules loaded into memory, but not XIP modules in ROM/FLASH.
This patch removes the mPmba global variable and instead reads the PIIX4 Power Management Base Address from PCI configuration space when it is needed. This patch also simplifies the initialization logic in the constructor and introduces #defines to eliminate hard coded values in the function implementations. According to the PIIX4 documentation, the IO Space enable bit in the PCI Command Register does not have to be set for the Power Management Base Address to be decoded, so that one op has been removed from the constructor.
I have tested this patch with QEMU and verified that the UDK Debugger us functional when SOURCE_DEBUG_ENABLE is set.

Set the boot order based on configuration retrieved from QEMU.
Attempt to retrieve the "bootorder" fw_cfg file from QEMU. Translate the
OpenFirmware device paths therein to UEFI device path fragments. Match the
translated fragments against the enumerated BootOptionList, and rewrite
the BootOrder NvVar so that it corresponds to the order described in
fw_cfg.
The user is expected to configure working boot options first.
Tested via virt-manager's boot order widget.

This patch adds support for a debug console on the same port that is used
by SeaBIOS. This makes it easier to debug OVMF, because it does not mix
debug and serial output on the same device. It also makes it easier to
leave some of the debug messages on even in release builds.
To enable it, pass "-debugcon stdio -global isa-debugcon.iobase=0x402" to
QEMU.
The new mechanism is enabled by default, but a regular serial console can
be chosen by adding -D DEBUG_ON_SERIAL_PORT to the build options.

Older QEMU versions would load vgabios-cirrus.bin at 0xc0000 in
system RAM. We would then find this ROM, and try to run it, since
it would be our QEMU Video driver.
Now, the QEMU Video driver is just merged into the main OVMF
firmware image, so this support is unused.

If the bit is not set, then the only method ACPI defines
for setting it is to use the SMI SCI enable code path.
Since OVMF does not support SMM, we must enable the
bit during boot.

If –D SECURE_BOOT_ENABLE is specified with the build command, Secure Boot support is enabled including custom mode setup.
This allows Secure Boot to be configured through setup allowing OvmfPkgX64, OvmfPkgIa32 and OvmfPkg3264 to be a fully functional Secure Boot reference platforms.
Remove redundant library class definitions for BaseCryptLib and OpenSslLib.
