Subject: SecurityPkg/Tcg2Dxe: suppress error on no swtpm in silent aa64 build
|
|
(RH)
|
|
|
|
Notes about the RHEL-8.3/20200603-ca407c7246bf [edk2-stable202005] ->
|
|
RHEL-8.5/20210520-e1999b264f1f [edk2-stable202105] rebase:
|
|
|
|
- Remove obsolete commit message tags related to downstream patch
|
|
management: Message-id, Patchwork-id, O-Subject, Acked-by, From,
|
|
RH-Acked-by, RH-Author (RHBZ#1846481).
|
|
|
|
Bugzilla: 1844682
|
|
|
|
If swtpm / vTPM2 is not being used, Tcg2Dxe should return EFI_UNSUPPORTED,
|
|
so that the DXE Core can unload it. However, the associated error message,
|
|
logged by the DXE Core to the serial console, is not desired in the silent
|
|
edk2-aarch64 build, given that the absence of swtpm / vTPM2 is nothing out
|
|
of the ordinary. Therefore, return success and stay resident. The wasted
|
|
guest RAM still gets freed after ExitBootServices().
|
|
|
|
(Inspired by RHEL-8.1.0 commit aaaedc1e2cfd.)
