[Q] Modifying bus clock frequency - General Questions and Answers

Is there any way to check the bus and DDR memory clock frequency on any of the latest Android devices (ASUS Transformer Prime based on Tegra3, or Samsung Note based on Exynos 4212). Is there any way to set the bus frequency to a particular clock?

(Question) CPU frequency control

Do you know a method or an application to force CPU speed to 1Ghz or at least how to control the current speed?
I find with TCPMP that, after a boot, CPU is running at maximum speed. After a few minutes it goes down to 500 - 400 Mhz and it does not raise anymore.
With 1 Ghz TCPMP runs smooth with GDI (the driver that let me use subtitles), with 500 Mhz it begins to stutter.
Another question, do you know a version of TCPMP that let you use subtitles using directdraw drivers?
Thanks
I want to know this ,too.

[Q] Read GPU Frequency of Intel Devices

Hi,
I am working on a program which reads the current GPU frequency of Android devices. For example, Adreno GPUs have a standard directory of /sys/class/kgsl/kgsl-3d0/gpuclk. The GPU frequency of Intel devices seems to be a lot more difficult to find. '/sys/class/drm/card0/gt_cur_freq_mhz' works for a few devices, but not all. Any ideas?
Thanks,
Andrew

Rockchip cpu model identification

Is there any tool to check for the exact cpu model for rockchip cpus?
I tried cpuz, cpu identification but none display it correctly

[BUG] MX player not using high powered cores to decode

I have a meizu MX4 (mediatek MT6595 8 core CPU in big.little configuration - 4*A7 + 4*A17) and I noticed that in some extreme cases where software decoding is required (aka a 10bit h265 video), the high powered cores are idle leaving the low powered cores to try to decode the exotic video format, unsuccessfully obviously.
I am currently on android KitKat but I can also test on android lolipop if required.
Try playing with CPU Core Limit
Settings>Decoder>Cpu core limit
You can also try "Use Speedup Tricks"

I tried changing the core limit settings, doesn't matter what settings I choose, only the low powered cores do anything but MX player detects all 8 cores.

This might be due to the the fact that SW decoder can't detect which one is faster and which one is slower.
You may get better performance by reducing number of cores to 4 to ignore slower cores.
Reducing the number of cores to 4 still uses the low powered cores exclusively. MX player simply refuses to load any of the high powered cores, no matter what setting.

It is solely kernel's decision selecting cores to be used..
Anyway I will check again if there is a way to control on it.

BTW, How did you monitor core usages? I can't find proper tool.
I'm pretty sure that choice of core usage is purely controlled by kernel logic; these big.LITTLE setups don't generally expose the cores to the OS.
