[Mesa-dev] [PATCH 00/11] i965: enable GPA

[Lionel Landwerlin]

Hi all,

One of the tool that Intel provides as part of a suite called GPA [1]
is a frame analyzer. This provides a way to look at per draw call or
frame workloads on the GPU through the OA hardware.

This tool relies on another library called MDAPI which requires a
somewhat specific format of data exchanged through the
GL_INTEL_performance_query extension.

This series implements this data format exchange while also providing
access to the raw delta values of the OA counters (see explanation in
patch 10). I've tried to put most of this stuff in its own file so
that it doesn't interact too much with the existing queries, while
also keeping the accumulation logic generic enough that it remains
shared code.

Hopefully that's not too hairy :)

Cheers,
