[Mesa-dev] [PATCH 0/5] Head-up display for Gallium DRI2 drivers

[Alexander Monakov]

I feel rather awkward asking, but: why implement this inside of
Gallium, instead of as a standalone {egl,glX}SwapBuffers interceptor
obtaining counter values via GL extensions, such as
ARB_occlusion_query or AMD_performance_monitor?  That way Intel (and
Nouveau?) people could also benefit from it.

Best regards,
Alexander
