Subject: [Qemu-devel] [PULL 05/12] i386: Remove osxsave CPUID flag name
Date: Mon, 25 Jun 2018 19:25:17 -0300 [thread overview]
Message-ID: <20180625222524.382-6-ehabkost@redhat.com> (raw)
In-Reply-To: <20180625222524.382-1-ehabkost@redhat.com>
OSXAVE is not a static feature flag: it changes dynamically at
runtime depending on CR4, and it was never configurable: KVM
never returned OSXSAVE on GET_SUPPORTED_CPUID, and it is not
included in TCG_EXT_FEATURES.
Remove OSXSAVE from the feature name array so users don't try to
configure it manually.
