Subject: [PATCH 01/13] kvm: selftests: vcpu_setup: set cr4.osfxsr
Date: Tue, 18 Sep 2018 19:54:24 +0200	[thread overview]
Message-ID: <20180918175436.19742-2-drjones@redhat.com> (raw)
In-Reply-To: <20180918175436.19742-1-drjones@redhat.com>

Guest code may want to call functions that have variable arguments.
To do so, we either need to compile with -mno-sse or enable SSE in
the VCPUs. As it should be pretty safe to turn on the feature, and
-mno-sse would make linking test code with standard libraries
difficult, we choose the feature enabling.
