Hello Robert,
Sorry for the delay, I just saw your message few days ago, and I
probably removed the mail by mistake too...
I have never heard about your work on this area, happy to know right now. :)
Well, regarding the backend stuff, I would prefer to keep the same for
both GL_AMD_performance_monitor and INTEL_performance_query.
Currently, I'm trying to implement GL_AMD_perfmon as a state tracker
which is based on the query interface of Gallium and this looks quite
good. Only minor changes in the current interface are required to do that.
At this time, most of hardware performance counters are *only* exposed
through the Gallium HUD and I think it's not very helpful for a large
number of applications.
I'm pretty sure that GL_AMD_perfmon will be very useful for exposing GPU
counters and this is also a requirement for a GSoC project this year.
So, with respect to your work, my question is : why do you want to get
rid of AMD_perfmon in favour of INTEL_perf_query ?
Don't you think that the AMD extension is also useful as the INTEL one?
Best regards,
Samuel Pitoiset.
