We don't seem to have reached much of an agreement on the general
direction of RFC2, so I can't really get started with it. Here is RFC1
for the record:
Specifically the following patch conflicts with this series:
Series improves performance-per-watt of GfxBench gl_4 (AKA Car Chase) by
over 15% on my system with the branch above, actual FPS "only" improves
about 5.9% on ICL laptop due to it being very lightly TDP-bound with its
rather huge TDP. The performance of almost every graphics benchmark
I've tried improves significantly with it (a number of SynMark
test-cases are improved by around 40% in perf-per-watt, Egypt
perf-per-watt improves by about 25%).
Hopefully we can come up with some alternative plan of action.
