Hi Jon,
> For my testing I have just been reading the PM_EMU_PWRSTST register which shows the power state of the EMU power domain. It should read 3 when the power domain is ON and 0 when it is off. I did something like the following (dumping all EMU clock and power domain registers).
I figured I may as well take perf for a spin and see how I got on. The good
news is that the hwmod bits all seem to work as before and the correct IRQs
are requested:
root@florentine-pogen:~# cat /proc/interrupts
CPU0 CPU1
29: 44527 17916 GIC twd
33: 0 0 GIC arm-pmu
34: 0 0 GIC arm-pmu
But, unfortunately, as you can see from the above, I just can't persuade them
to fire. The PMU counters do tick, but they happily increment through zero
without us realising. I retested with my perf/omap4 branch to make sure my
board is ok, and the irqs do fire there.
Any ideas?
Cheers,
Will
