Hi,
This is a much improved version of diplayable DCC support.
GpuTest/Triangle: No change in performance.
GLMark2: -0.5% performance
glxgears: There seems to be a small difference, but it might also be
just noise.
See the changes in patches 4-8, but generally this is enough to enable
DCC for cases where we need it the most.
- Patch 1 only has cosmetic changes.
- Ignore patches 2-3 that just happen to be there.
- Patches 4-8 contain additional improvements that fix performance
losses from the first patch while not decreasing performance for
benchmarks that we care about.
Looks good. I was going to suggest that perhaps the impact of
perfcounters could still be reduced by only collecting data from a
single backend pipeline and scaling the numbers up (assuming an even
distribution of load), but seems like that's not even really necessary
anymore.
Patches 1, 4 - 8:

Please review.
