GPU voltage control #52
Comments
Looks like the only part of that which is pertinent is:
I'll see if I can't add it. Though, I'm not entirely sure exactly how I'm going to get it going reliably for all devices. Also, I don't even know of any kernels that actually use this... and I'd also need an example of the sysfs node that this references. |
Sorry for my late reply. I can provide an example of the sysfs node until the weekend. I have merged 'GPU voltage control' into my 'Revival kernel' for mako. ;) Basically it is a nice addition for Snapdragon/adreno based devices with custom kernel. There are a few custom kernels out there with this feature, but I can't remember exactly which ones. |
No worries. If you can provide the examples, I'll try to add it. |
When I make an ouput of the sysfs node I get a vector with these defaults: Do you need the max and min values, as well? I need to look into the source code to figure out.. |
Here we go. I couldn't find where they define the steps. So I assume that it can be defined as we need it (e.g.: 5mV). #define GPU_MIN_VDD 900 |
This feature is currently only supported by Synapse. Would be nice to have it in KA-mod as well.
