Greetings,
I'd like to know the different recommended ways to quickly check and, if possible, set the current frequency of the Mali GPU used by a Linux kernel patched with the Mali kernel-space drivers, once the system is booted of course. The reason is that I'd like to know if my installation is correct and if the GPU is running at its highest frequency when needed.
For reference, I'm running a linux 4.9-rc4 system patched with the latest Mali Kernel Driver, on a RK3288 board.
Best regards
The DVFS integration isn't part of the core Mali DDK we provide; it's added by the chipset manufacturer depending on the analogue properties of their system, and their power controller / clock generation.
HTH, Pete
