Subject: [RFC 09/10] i386/cpu: Enable 0x1f leaf for GraniteRapids by default
Date: Wed, 23 Apr 2025 19:47:01 +0800	[thread overview]
Message-ID: <20250423114702.1529340-10-zhao1.liu@intel.com> (raw)

Host GraniteRapids CPU has 0x1f leaf by default, so that enable it for
Guest CPU by default as well.
