Subject: [PATCH 1/3] OvmfPkg/AmdSev: fix BdsPlatform.c assertion failure
during boot
RH-Author: Gerd Hoffmann <None>
RH-MergeRequest: 44: OvmfPkg/AmdSev: fix BdsPlatform.c assertion failure during boot
RH-Bugzilla: 2190244
RH-Acked-by: Oliver Steffen <osteffen@redhat.com>
RH-Commit: [1/1] 44f18b2324cbd4aa1840613d9a8d19f0fbec7b1b (kraxel.rh/centos-src-edk2)
Booting an SEV guest with AmdSev OVMF package currently triggers the
following assertion with QEMU:
InstallQemuFwCfgTables: installed 7 tables
PcRtc: Write 0x20 to CMOS location 0x32
[Variable]END_OF_DXE is signaled
Initialize variable error flag (FF)
ASSERT_EFI_ERROR (Status = Not Found)
ASSERT [BdsDxe] /home/VT_BUILD/ovmf/OvmfPkg/Library/PlatformBootManagerLib/BdsPlatform.c(1711): !(((INTN)(RETURN_STATUS)(Status)) < 0)
This seems to be due to commit 81dc0d8b4c, which switched to using
PlatformBootManagerLib instead of PlatformBootManagerLibGrub. That
pulls in a dependency on gEfiS3SaveStateProtocolGuid provider being
available (which is asserted for in
BdsPlatform.c:PlatformBootManagerBeforeConsole()/SaveS3BootScript()),
but the libraries that provide it aren't currently included in the
build. Add them similarly to what's done for OvmfPkg.
Fixes: 81dc0d8b4c ("OvmfPkg/AmdSev: stop using PlatformBootManagerLibGrub")

RH-MergeRequest: 46: OvmfPkg/AmdSevDxe: Shim Reboot workaround (RHEL only)
RH-Bugzilla: 2218196
RH-Acked-by: Gerd Hoffmann <None>
RH-Commit: [1/1] 9bf3bb989e36253aa34bf82ecfe8faa7312e8d22 (osteffen/edk2)
Add a callback at the end of the Dxe phase that sets the
"FB_NO_REBOOT" variable under the Shim GUID.
This is a workaround for a boot loop in case a confidential
guest that uses shim is booted with a vtpm device present.

Subject: [PATCH 2/3] OvmfPkg/IoMmuDxe: add locking to
IoMmuAllocateBounceBuffer
RH-Author: Gerd Hoffmann <None>
RH-MergeRequest: 45: OvmfPkg/IoMmuDxe: add locking to IoMmuAllocateBounceBuffer
RH-Bugzilla: 2211060
RH-Acked-by: Oliver Steffen <osteffen@redhat.com>
RH-Commit: [1/1] c4998c57651df23342a0cd6e8982bf59f306da83 (kraxel.rh/centos-src-edk2)
Searching for an unused bounce buffer in mReservedMemBitmap and
reserving the buffer by flipping the bit is a critical section
which must not be interrupted. Raise the TPL level to ensure
that.
Without this fix it can happen that IoMmuDxe hands out the same
bounce buffer twice, causing trouble down the road. Seen happening
in practice with VirtioNetDxe setting up the network interface (and
calling into IoMmuDxe from a polling timer callback) in parallel with
Boot Manager doing some disk I/O. An ASSERT() in VirtioNet caught
the buffer inconsistency.
Full story with lots of details and discussions is available here:
https://bugzilla.redhat.com/show_bug.cgi?id=2211060
