This commit removes OVMF IA32 from edk2 per RFC
https://edk2.groups.io/g/devel/topic/rfc_remove_ovmf_ia32_and/114152215.
OVMF IA32 is a 32 bit only platform that no longer represents the vast
majority of physical platforms. The RFC details more reasoning in
much more depth.
OVMF IA32 will be kept in a branch off the edk2-stable202508 tag for
any long term consumers; it will receive build break updates only
(e.g. if an upstream submodule changes location).

OvmfPkg/MemEncryptSevLib: Check if SEV-SNP coherency mitigitation is needed2025-09-09T17:43:31+00:00Tom Lendackythomas.lendacky@amd.com2025-07-22T20:06:18+00:00urn:sha1:20f24c0f67b3364cd590e1eea470f74be40e7710
CPUID bit Fn8000001F_EBX[31] defines the COHERNECY_SFW_NO CPUID bit that,
when set, indicates that the software mitigation for this vulnerability is
not needed.
Add support to check for this CPUID bit and avoid the mitigation if set.

OvmfPkg/MemEncryptSevLib: Evict cache lines during SNP memory validation2025-09-09T17:43:31+00:00Tom Lendackythomas.lendacky@amd.com2025-08-12T19:43:32+00:00urn:sha1:3b0d834db286a236fd22c41923fc271fc44ead5f
An SNP cache coherency vulnerability may require a mitigation to evict
cache lines after memory has been validated. Perform this mitigation
after having validated memory.

There is no good reason to keep QemuFwCfgSimpleParserLib arch-specific.
Move it to the LibraryClasses section.

OvmfPkg/MemDebugLogLib: unoptimize PEIM and PEI_CORE2025-08-28T09:56:09+00:00Luigi Leonardileonardi@redhat.com2025-07-14T15:19:36+00:00urn:sha1:839e79f62b368475d2af5c2fd9d18c77a57fb8a7
In AARCH64, the PEI phase runs from the flash memory, therefore global
variables are not allowed.
Remove this optimization so that this library can be used for this
architecture.

OvmfPkg/AmdSvsmLib: add AmdSvsmQueryProtocol2025-07-16T00:09:22+00:00Gerd Hoffmannkraxel@redhat.com2025-06-04T10:32:48+00:00urn:sha1:29477c2045ec90e12231421489427e2ac1ee69ee

OvmfPkg/PlatformDebugLibIoPort: Add check for MemDebugLogWrite2025-07-08T06:04:46+00:00Luigi Leonardileonardi@redhat.com2025-06-27T14:39:34+00:00urn:sha1:fb55173551c785bb1c5883a0324f2deea1d94384
This check is present for every call to `MemDebugLogWrite` but it is
missing here. This may cause an unwanted write to the
buffer, when the buffer's address is not null and MemDebug is disabled.

OvmfPkg: Don't Allocate Page 02025-07-08T03:45:09+00:00Oliver Smith-Dennyosde@microsoft.com2025-06-17T22:28:14+00:00urn:sha1:83b30736bfb57b3895a089968319fb5c0cd42a28
OvmfPkg has copied the MdeModulePkg DxeIpl behavior to
create a memory allocation HOB for page 0. That is being changed
(see that commit for details), so also remove it here.

OvmfPkg: Add the ResetVector in TDX MailBox2025-06-20T02:23:42+00:00Ceping Suncepingx.sun@intel.com2023-12-01T02:00:32+00:00urn:sha1:406f42cb74fbdac1fdf6a90c72fb7b4ca67107ff
Base on ACPI 6.6 Multiprocessor Wakeup Structure, TDVF needs to provide
a physical address of the ResetVector to OS. And it should allow the
Multiprocessor Wakeup Mailbox to be reset in order to be used once again
with a given AP.
