Subject: [PATCH 3/9] i386/cpu: Add support for bits in CPUID.7_2.EDX
Date: Wed, 14 Aug 2024 03:54:25 -0400	[thread overview]
Message-ID: <20240814075431.339209-4-xiaoyao.li@intel.com> (raw)
In-Reply-To: <20240814075431.339209-1-xiaoyao.li@intel.com>

KVM started to report the support of bit 0-5 since commit eefe5e668209
("Advertise CPUID.(EAX=7,ECX=2):EDX[5:0] to userspace")

Allow them to be exposed to guest in QEMU.
