[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH][SVM] Remove more MSR intercepts that are redundant.
Further to yesterdays patch removing FS/GS-base MSR intercepts, this patch: 1. Removes intercept of guest-specific MSRs MSR_IA32_SYSENTER_{CS,ESP,EIP}, MSR_{L,C,}STAR, MSR_SYSCALL_MASK, MSR_SHADOW_GS_BASE. 2. Removes code to deal with those intercepts, as well as the FS/GS-base. Since long_mode_do_msr_read now became essentially a switch of a single case + default, I removed the entire function and inlined the remaining single case-statement into the original MSR-access function. In a normal system, this probably doesn't improve performance (or otherwise affect anything), but it removes some code that isn't needed - which I think is as good a reason as any. I'd appreciate if this is applied. Applies to c/s: 14967 Signed off by: Mats Petersson <mats.petersson@xxxxxxx> -- Mats Attachment:
