3D graphics driver for the Adreno family of GPUs from QTI.

GPU frequency governor for the Adreno GPU. Sets the frequency

using an "on demand" algorithm in conjunction with other

components on Adreno platforms. This is not useful for non-Adreno

devices.

This governor works together with the Adreno GPU governor to

select bus frequency votes using an "on-demand" algorithm.

This governor will not be useful for non-Adreno based

targets.

When enabled, the Adreno GPU is available as a source for Coresight

Say 'Y' here to enable I/O cache coherency by default on targets that

support hardware I/O coherency. If enabled all cached GPU memory
|

the user can still selectively enable I/O coherency with a flag.

GPU idle timeout for Adreno GPU. This value decides after how

the GPU is powered ON for a longer duration which will have

When enabled, total number of KGSL contexts, number of attached and

detached contexts are dumped into kernel log for all the processes.
