Also known as Paravirtualization CPUIDs. This is primarily done so that the guest will think it is running under vmware when hypervisor-vendor=vmware is specified as a property of a cpu. Patches 1 to 3 define new cpu properties. Patches 4 to 6 Add QOM access to the new properties. Patches 7 to 9 Add setting of these when cpu features hv_spinlocks, hv_relaxed, or hv_vapic are specified. Patches 10 to 12 Change kvm to use these. Patch 13 Add VMware timing info to kvm. Patch 14 Makes it easier to use hypervisor-vendor=vmware. Patches 15 to 17 Change tcg to use the new properties. This depends on: http://lists.gnu.org/archive/html/qemu-devel/2012-09/msg01400.html As far as I know it is #4. It depends on (1) and (2) and (3). This change is based on: Microsoft Hypervisor CPUID Leaves: http://msdn.microsoft.com/en-us/library/windows/hardware/ff542428%28v=vs.85%29.aspx Linux kernel change starts with: http://fixunix.com/kernel/538707-use-cpuid-communicate-hypervisor.html Also: http://lkml.indiana.edu/hypermail/linux/kernel/1205.0/00100.html VMware documention on CPUIDs (Mechanisms to determine if software is running in a VMware virtual machine): http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1009458 Changes from v6 to v7: Subject changed from "Allow changing of Hypervisor CPUIDs." to "target-i386: Add way to expose VMWare CPUID" Split out 01/16 target-i386: Add missing kvm bits. It is no longer related to this patch set. Will be top posted as a seperate patch. Marcelo Tosatti: Better commit messages. Reorder patches. Changes from v5 to v6: Split out 01/17: target-i386: Allow tsc-frequency to be larger then 2.147G It has been accepted as a trivial patch: http://lists.gnu.org/archive/html/qemu-devel/2012-09/msg03959.html Blue Swirl: Fix 2 checkpatch.pl "WARNING: line over 80 characters". Changes from v4 to v5: Undo kvm_clock2 change. Add cpuid_hv_level_set; cpuid_hv_level == 0 is now valid. Add cpuid_hv_vendor_set; the null string is now valid. Handle kvm and cpuid_hv_level == 0. hypervisor-vendor=kvm,hypervisor-level=0 and hypervisor-level=0,hypervisor-vendor=kvm now do the same thing. Changes from v3 to v4: Added CPUID_HV_LEVEL_HYPERV, CPUID_HV_LEVEL_KVM. Added CPUID_HV_VENDOR_HYPERV. Added hyperv as known hypservisor-vendor. Allow hypervisor-level to be 0. Changes from v2 to v3: Clean post to qemu-devel. Changes from v1 to v2: 1) Added 1/4 from http://lists.gnu.org/archive/html/qemu-devel/2012-08/msg05153.html Because Fred is changing jobs and so will not be pushing to get this in. It needed to be rebased, And I needed it to complete the testing of this change. 2) Added 2/4 because of the re-work I needed a way to clear all KVM bits, 3) The rework of v1. Make it fit into the object model re-work of cpu.c for x86. 4) Added 3/4 -- The split out of the code that is not needed for accel=kvm. Changes from v2 to v3: Marcelo Tosatti: Its one big patch, better split in logically correlated patches (with better changelog). This would help reviewers. So split 3 and 4 into 3 to 17. More info in change log. No code change.
