These two patches are focued on providing a basic version of VMX nested
test suite. This commit provides the architecture of nested VMX similiar
to x86/svm.c.
When new test suite added, just write functions included in struct vmx_test
and register it in array vmx_tests. GPR in guest can be read
Add setjmp and longjmp functions to libcflat. Now these two functions
are only supported in X86_64 arch.
New files added:
lib/x86/setjmp64.S
lib/x86/setjmp64.c

This is the first version for VMX nested environment test case. It
contains the basic VMX instructions test cases, including VMXON/
VMXOFF/VMXPTRLD/VMXPTRST/VMCLEAR/VMLAUNCH/VMRESUME/VMCALL. This patch
also tests the basic execution routine in VMX nested environment and
let the VM print Hello
Hi Gleb and Paolo,
As your suggestion, I add general interface for adding test suite in
this version. It is similar to the achievement of x86/vmx.c, and I
also move tests for vmenter (vmlaunch and vmresume test) to an
independent test suite.

The first concern is Gleb's way cannot set a seperate stack for

Add support for error containment when a VFIO device assigned to a KVM
guest encounters an error. This is for PCIe devices/drivers that support AER
functionality. When the host OS is notified of an error in a device either
through the
Turns out all the suspicions for AMD devices were correct, everywhere
we read a BAR address that the address matches the config space offset,
there's full access to PCI config space. Attempt to generalize some
helpers to allow quirks to easily be added for mirrors and windows.
Also fill in
Does the host system support constant_tsc? Check /proc/cpuinfo. It could
be that too many ticks are being lost in the guest.

Hi,
It is sound and _hardware_ not sure why MS separated sound from HW :)
OK, I'll check it
Try it and see if
Currently, fast page fault tries to fix mmio page fault when the
generation number is invalid (spte.gen != kvm.gen) and returns to
guest to retry the fault since it sees the last spte is nonpresent
which causes infinity loop
It can be triggered only on AMD host since the mmio page fault is

Window2008 will not use TSC as a time source while running as a guest.

This corrects the usage of the tlbie (TLB invalidate entry) instruction
in HV KVM. The tlbie instruction changed between PPC970 and POWER7.
On the PPC970, the bit to select large vs. small page is in the instruction,
not in the RB register value. This

err was overwritten by a previous function call, and checked to be 0. If
the following page allocation fails, 0 is going to be returned instead
of -ENOMEM.

No, we don't put it in CCSR space. It'd just be orthogonal to CCSR.
