Sorry for the delay in responding. As far as I know this has not happened. Such a change would also have to include making the use of timer interrupts (as opposed to PMU counter interrupts) selectable at runtime. I believe the use of timer interrupts for oprofile data collection is still a configuration/boot option. Alternatively we could just decide to deconfigure PMU hardware counters by default to make timers accessible. -dl _______________________________________________ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev
