Subject: OvmfPkg/QemuKernelLoaderFsDxe: suppress error on no "-kernel" 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 the "-kernel" QEMU option is not used, then QemuKernelLoaderFsDxe
|
|
should return EFI_NOT_FOUND, 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 "-kernel" 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.)
