[PATCHv2] export clock debug information to user space

2010-11-25 Thread Yong Shen
Hi Jeremy, Sorry for delay sending out this patch, I was slow down by other things and eye infection :( I followed your suggestion to make clock debug interface cleaner and more independent, like removing unnecessary #ifdef and moving all operations to kernel/clk.c. >From 2b6c378c3c42d695f72f987e

[PATCH] OMAP PM: Optimize cpufreq transition latency

2010-11-25 Thread Vishwanath BS
Currently cpufreq transition latency value does not really reflect the actual OMAP OPP transition delay. This patch has the actual latency value. I did profile the DVFS latency on OMAP3430, OMAP3630 and OMAP4 for worstcase(MPU and Core together) and found that in none of these platforms, transito

Thanks David. If I would like to fine tune up_threshold and sampling_down_factor for say OMAP platform, is there any way to do it in kernel itself? I know these are configurable via sysfs entries. But if I want to optimize them in kernel itself, is there anyway? I see that default values are set in

Thanks for running the tests, Vishwa. Your results are what I'd expect but it's good to see independent confirmation. In my benchmarks I saw 95-100% of the performance governor's performance, but the conditions were more favorable and the original ondemand governor was "only" degrading performan
