Hi all, I working with pm-2.6.34 based kernel on Beagleboard. I am not working with later kernels because I need cpufreq (which is currently not supported due to upgradation).
My project requires cpufreq transitions at inter-task/intra-task levels and when I made the changes for that., it seems to be working fine for some time. However, after a few seconds, the system freezes and it seems like it is freezing when the frequency is changed. I wish I could point out which function is executing when this happens, however, the behaviour seems to be changing when i instrument the code with printks. But, based on a few runs, it looks like usually the system freezes when arch\arm\mach-omap2\Resource34xx.c::program_opp() is invoked. I understand sometime down the line when cpufreq is enabled again in linux-omap-pm, I might not have this issue at all. However, as I am stuck with pm-2.6.34 for now, has anybody seen this kind of a problem before? and is there any way to avoid this (other than possibly reducing the frequency of changes to cpufreq)? -hari -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
