[Xen-devel] Re: [PATCH] Use hypercalls instead of accessing debug regist
Ian Pratt wrote: Use hypercalls instead of accessing debug registers directly.Is this based on measurement? If the debug registers aren't on the critical path its probably not worth the change. If they are, they should probably be part of a multicall. It's not on the critical path. We probably should just emulate the instruction on the GP fault.
