<aborche>
how i can find why ?
<aborche>
i need repair pwm settings. can you run compiled kernel at radxa rock ? radxa rock lite ?
<aborche>
i think problem in dts

mmind00, sow how does cpufreq work on rk3188? I could only find this line: "platform_device_register_simple("cpufreq-dt", 0, NULL, 0);"in rockchips.c
<mmind00>
BorgCuba: simply by adjusting frequency and voltages via the cpufreq-dt driver
<BorgCuba>
mmind00, I am only asking since I think at least for me (and my configuration) it does not seem to work. When I look it up in /sys and debugfs the values seem to be alright but when I run my benchmarks (dhrystone & nbench) nothing changes
<BorgCuba>
and I think the 300MHz DDR clock is okay
<mmind00>
BorgCuba: that is around half of the max frequency
<mmind00>
aka DDR3-1066 can run at 533MHz
<BorgCuba>
yes, but the values do not change in any way and I think dhrystone should not be bottlenecked by dram speed?
<BorgCuba>
so if I make a linear estimation: 300->533 < 50% inc; dhrystone performance with old kernel is at least 50% faster, almost 75%

<BorgCuba>
it uses blocks of different size, so I think at least for the smallest (8k) block there should be a difference (cache), but there isn't any difference
<BorgCuba>
I fear thats not working
<BorgCuba>
has anyone really tested this (on rk3188) measuring the difference in performance?
<aborche>
BorgCuba, are you see my previous message ?

mmind00: i don't think my sound issue is related to the ucms. the driver in upstream is somewhat different from the chromiumos kernel one...and i dunno, the hanging behaviour i see isn't what i'd expect from a ucm issue
<via>
if you have any ideas on how i could debug this i'm all ears
<mmind00>
via: sadly nope, I haven't looked deeper into anything sound-related
<via>
ok
