ARM PMU is not something I know very much about, and I really don't understand why I'm on the CC list and not the ARM PMU folk. I may be mis-stating a problem, but I believe that we have issues with exporting event IDs in that they're SoC implementation specific - but as I say, the ARM PMU guys know the details not me. I strongly suggest no further discussion without at least looping Will Deacon in on this. -- Russell King Linux kernel 2.6 ARM Linux - http://www.arm.linux.org.uk/ maintainer of:
