[Android] How to keep GPU clock active?

[charleshuang]

Hi Freescale,

We have several questions about GPU on Android.

Q1. As I known, GPU clock may be closed when GPU is suspend. So, how could I keep GPU clock always active?

Q2. We can get CPU information from /sys/devices/system/cpu/ via kernel command line.

       However, how to get GPU related information? such as GPU clock frequency, status, etc.

Thanks,

Daniel

Hi charles

for clock frequencies one can use dump-clocks.sh utility provided in

Re: increase CPU/GPU frequency on iMX6 Solo

for GPU one can set parameter in ../gc_hal_options.h, gcdPOWEROFF_TIMEOUT to zero.

kernel_imx/gc_hal_options.h at master · boseji/kernel_imx · GitHub

Best regards

igor
