Subject: [PATCH RFC v2 08/28] OvmfPkg/BaseMemEncryptSevLib: Remove CacheFlush parameter
Date: Fri, 30 Apr 2021 06:51:28 -0500 [thread overview]
Message-ID: <20210430115148.22267-9-brijesh.singh@amd.com> (raw)
In-Reply-To: <20210430115148.22267-1-brijesh.singh@amd.com>
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3275
The CacheFlush parameter is used to provide hint whether the specified
range is Mmio address. Now that we have a dedicated helper to clear the
memory encryption mask for the Mmio address range, its safe to remove the
CacheFlush parameter from MemEncryptSev{Set,Clear}PageEncMask().
