Subject: oprofile on OMAP2: ARM11 PMU interrupts?
Date: Fri, 26 Oct 2007 10:37:58 -0700 [thread overview]
Message-ID: <472225F6.9070502@mvista.com> (raw)
Is anyone using oprofile on OMAP2?
A quick test of the current code in current git doesn't seem to work. I
see the PMU being configured, IRQ3 being registered but no interrupts
ever fire on that IRQ, and thus no data is collected.
I tested on a 2420/H4 and 2430SDP with same results. In both cases, the
IRQ is configured to IRQ3, which in the TRM says 'BENCH MPU emulation'.
I have no idea what that means, but it doesn't sound like the ARM11 PMU
interrupt to me though.
Any ideas?
Kevin
