Perf events for GPU drivers
As perf supports system-wide events (soon), it would be really useful to have the kernel device drivers for GPUs generate perf events to improve profiling.

[ChunsangJeong Jul 26 2011]
Got Origen board to colsolidate Mali driver in Jul 24. Moved Mali activation on Origen board from 2011.07
[ChunsangJeong Aug 15 2011]
Updated Mali r2p2-03rel0 to git://git.
Verified it worked on linux-linaro-3.0 kernel.
[ChunsangJeong Aug 17 2011]
Needed GPU perf events, which describe each of GP and PPs time stamps with CPU usage on user space, can be reused for "perf events for GPU profiling", which was already included in the latest mai kernel driver, discussed with ARM MPD (Orjan on Q3 Connect)
Headline:
Verified Mali r2p2-03rel worked on linux-linaro-3.0.
