[Xen-devel] Incorrect Comment in xen/include/asm-x86/hvm/svm/vmcb.h

[Dushyant Behl <myselfdushyantbehl@xxxxxxxxx>]

Hi Everyone,

I was looking at the SVM setup code in Xen when I noticed that some
comments describing the VMEXIT codes look wrong.
The processor exception exitcodes listed from VMEXIT_EXCEPTION_PF to
VM_EXCEPTION_XF seem to describe the hexadecimal exit code different
than the expected value.

This section is taken from xen/include/asm-x86/hvm/svm/vmcb.h

VMEXIT_EXCEPTION_PF  =  78, /* 0x4f, page-fault */
VMEXIT_EXCEPTION_15  =  79, /* 0x50, reserved */
VMEXIT_EXCEPTION_MF  =  80, /* 0x51, x87 floating-point exception-pending */
VMEXIT_EXCEPTION_AC  =  81, /* 0x52, alignment-check */
VMEXIT_EXCEPTION_MC  =  82, /* 0x53, machine-check */
VMEXIT_EXCEPTION_XF  =  83, /* 0x54, simd floating-point */

The expected exception code for page-fault is 78 which should be 0x4E
in hexadecimal, same case for all the exceptions till XF.
If this needs correction please let me know, will be happy to submit a patch.

Thanks,
Dushyant Behl
