KVM: SVM: Fix FPU leak while emulating clts

2007-11-27T13:38:18+00:00

The clts code didn't use set_cr0 properly, so our lazy FPU
processing wasn't being done by the clts instruction at all.

(this isn't called on Intel as the hardware does the decode for us)

KVM: SVM: Unload guest fpu on vcpu_put()

2007-11-27T13:33:10+00:00

Not unloading the guest fpu can cause fpu leaks from guest to guest (or host
to guest).

KVM: x86 emulator: Use emulator_write_emulated and not emulator_write_std

2007-11-27T13:28:29+00:00

emulator_write_std() is not implemented, and calling write_emulated should
work just as well in place of write_std.

Fixes emulator failures with the push r/m instruction.

KVM: x86 emulator: fix the saving of of the eip value

2007-11-27T13:10:45+00:00

this make sure that no matter what is the operand size,
all the value of the eip will be saved

KVM: x86 emulator: fix JMP_REL

2007-11-27T13:08:22+00:00

Change JMP_REL to call to register_address_increment(): the operands size
should not effect the calculation of the eip, instead the ad_bytes should
affect it.

KVM: SVM: Intercept the 'invd' and 'wbinvd' instructions

2007-11-08T10:05:45+00:00

'invd' can destroy host data, and 'wbinvd' allows the guest to induce
long (milliseconds) latencies.

KVM: x86 emulator: invd instruction

2007-11-08T10:05:44+00:00

Emulate the 'invd' instruction (opcode 0f 08).

KVM: SVM: Defer nmi processing until switch to host state is complete

2007-11-08T10:05:43+00:00

If we stgi() too soon, nmis can reach the processor even though interrupts
are disabled, catching it in a half-switched state.  Delay the stgi() until
we're done switching.

KVM: SVM: Fix SMP with kernel apic

2007-11-08T10:05:36+00:00

AP processor needs to reset to the SIPI vector, not normal INIT.

KVM: x86 emulator: fix 'push imm8' emulation

2007-11-08T08:42:04+00:00

'push imm8' found itself in the wrong switch somehow, so it is never executed.

This fixes Windows 2003 installation.
