X-Received-From: 134.134.136.20 Subject: [Qemu-devel] [PATCH v4 0/3] x86: QEMU side support on MSR based features X-BeenThere: qemu-devel@nongnu.org X-Mailman-Version: 2.1.21 Precedence: list List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Cc: robert.hu@intel.com, qemu-devel@nongnu.org, Robert Hoo Errors-To: qemu-devel-bounces+incoming=patchwork.ozlabs.org@nongnu.org Sender: "Qemu-devel" KVM side has added the framework (kvm.git:d1d93fa90) to support MSR based features. Here is the QEMU part, including data structure changes/expanding, referring functions changes, and the implementations on KVM_GET_MSR_FEATURE_INDEX_LIST and KVM_GET_MSRS system ioctl. Changelog: v4: Re-organize patch set to conform to request of individually build pass. Add KVM capability check for KVM_GET_MSR_INDEX_LIST before fetch. Special treatment for MSR_IA32_ARCH_CAPABILITIES.RSBA. Use more convenient glib wrapper (g_strdup_printf) instead of native (sprintf). v3: patch 2&3 in v2 are corrupted. Re-format patches. v2: coding style changes to pass ./scripts/checkpatch.pl.
