Re: NVIDIA Xen 3.0 Patch for driver 100.14.11
I just had a look at the patch: it includes left-overs from
the unified xen/rt patch concerning the -rt part that are not any
more necessary with recent NIVDIA drivers and Linux kernels:
PAT support can fully stay enabled with -rt, because the cache
flushing is today not done by a high latency causing "wbinvd"
instruction but by a series of individual cache line flushing
instructions. So the two occurances of CONFIG_PREEMPT_RT
can be deleted, resulting in slightly better 3D performance.
