Setting custom GPU Voltages via sysfs

NB:
- Safe lock is present on MIN/MAX values:

Quote:
#define GPU_MIN_VDD 900000
#define GPU_MAX_VDD 1200000
The default GPU voltages are:
Quote:
+ [VDD_DIG_NONE] = 0,
+ [VDD_DIG_LOW] = 975000,
+ [VDD_DIG_NOMINAL] = 1075000,
+ [VDD_DIG_HIGH] = 1175000
Verify the actual settings:
Quote:
cat /sys/devices/system/cpu/cpu0/cpufreq/gpu_mv_table

975000
1075000
1175000


Adjust to desired values and verify:

Quote:
echo "930000 1000000 1100000" > /sys/devices/system/cpu/cpu0/cpufreq/gpu_mv_table


compatible roms
carbon rom
beanstalk rom
AICP kk rom
aokp rom
cm11 rom
more testing needed

Is booting without any problems. Underclocked to 196 and everything seems to be working.

And the best thing: The annoying soundbug is gone!

Where can I buy u a beer?

*throwig thanks to the monitor*

 

[ojessie]

Wow, thanks a kernel for CM

 

[owlwood]

Awesome, nice to see a new kernel for ZL!

Wi-Fi doesn't work for me and there are some visual glitches when scrolling, though.

which rom

 

[owlwood]

which rom

Paranoid Android, latest build.

 

[nikhil18]

Paranoid Android, latest build.

so the rom is not supported because it has different source code from cm

 

[sualfred]

wifi is working and no glitches while scrolling @cm11 nightly.

I dont know if its possible but do u think that implementing whitebalance display settings is possible? Remember there was a setting to adjust mdnie on my recent mobile and the stock roms also provides a feature like that.

And I wisg my notification LED could pulse instead of just blinking

its already implimented but you need faux clock app

 

[sualfred]
