Subject: [Qemu-devel] [PATCH 5/5] i386: Add new CPU model Icelake-{Server, Client}
Date: Mon, 25 Jun 2018 11:39:21 +0800	[thread overview]
Message-ID: <1529897961-134132-6-git-send-email-robert.hu@linux.intel.com> (raw)
In-Reply-To: <1529897961-134132-1-git-send-email-robert.hu@linux.intel.com>

New CPU models mostly inherit features from ancestor Skylake, while addin new
features: UMIP, New Instructions ( PCONIFIG (server only), WBNOINVD,
AVX512_VBMI2, GFNI, AVX512_VNNI, VPCLMULQDQ, VAES, AVX512_BITALG),
Intel PT and 5-level paging (Server only). As well as
IA32_PRED_CMD and IA32_ARCH_CAPABILITIES MSRs, SSBD support for speculative execution
side channel mitigations.

Note: For 5-level paging, Guest physical address width can be configured, with
parameter "phys-bits". Unless explicitly specified, we still use its default
value, even for Icelake-Server cpu model.
