Subject: gallium: enable intel jitevents profiling
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b65f7ec4507122d2a3f258b7ca7c6809de06f097;p=mesa.git

gallium: enable intel jitevents profiling

LLVM when configured with "intel jitevents" enabled can inform
VTune about dynamic code, so individual shaders are attributed
profiling data and the resulting assembly can be examined.
