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.
Please use checkpatch.pl to check for missing braces etc.
I have been. Somehow missed the warnings on the posted patches. v6 in
the works.
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 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.
