Subject: [PATCH 0/2] Fixes for TCG/HVF warning of CPUID_HT and CPUID_EXT3_CMP_LEG
Date: Tue, 13 May 2025 23:16:50 -0400 [thread overview]
Message-ID: <20250514031652.838763-1-xiaoyao.li@intel.com> (raw)
Starting from QEMU v10.0.0, QEMU hits warnings when vcpus >= 2 with TCG
qemu-system-x86_64: warning: TCG doesn't support requested feature: CPUID.01H:EDX.ht [bit 28]
qemu-system-x86_64: warning: TCG doesn't support requested feature: CPUID.80000001H:ECX.cmp-legacy [bit 1]
For HVF, it should have the same warning of CPUID.01H:EDX.ht [bit 28].
This series tries to fix them.

i386/tcg: Make CPUID_HT and CPUID_EXT3_CMP_LEG supported
