Subject: [PATCH 1/1] MdeModulePkg/Gcd: Fix bug of attribute conversion
Date: Thu, 29 Mar 2018 16:19:50 +0800 [thread overview]
Message-ID: <1522311590-104218-1-git-send-email-heyi.guo@linaro.org> (raw)
For gDS->SetMemorySpaceAttributes(), when user passes a combined
memory attribute including CPU arch attribute and other attributes,
like EFI_MEMORY_RUNTIME, ConverToCpuArchAttributes() will return
INVALID_CPU_ARCH_ATTRIBUTES and skip setting page/cache attribute for
the specified memory space.
We don't see any reason to forbid combining CPU arch attributes and
non-CPU-arch attributes when calling gDS->SetMemorySpaceAttributes(),
so we remove the check code in ConverToCpuArchAttributes(); the
remaining code is enough to grab the interested bits for
Cpu->SetMemoryAttributes().
