Question regarding ASM_VMX_VMXON_RAX

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

The SDM defines the opcode of the VMXON instruction as F3 0F C7 /6,
yet in the kernel source code (arch/x86/include/asm/vmx.h) I saw:

#define ASM_VMX_VMXON_RAX         ".byte 0xf3, 0x0f, 0xc7, 0x30"

So what is 0x30 used for? And why there is no "/6"?

I saw this 0x30 in several other macros as well, such as
ASM_VMX_VMCLEAR_RAX and ASM_VMX_VMPTRLD_RAX.

Where in the SDM, can I find some explanation to this 0x30? Thanks.
