Can't overclock the GPU on a Pi 4B #65

Well, running Android TV on the Pi 4B and overclocking the CPU and video decoders seems functional but v3d or gpu core clocks won't go above 450 MHz no matter what. I did the config.txt edits on both Android TV 13 and 14. Screenshot_20240217-075914_Termux Screenshot_20240217-075839_Termux

This is something that is handled on the firmware level and there's nothing Android specific here. Please refer to the Raspberry Pi documentation on the subject. https://www.raspberrypi.com/documentation/computers/config_txt.html#overclocking-options

Sure but overclocking on PiOS worked. That's what's got me puzzled.

Something that could depend on e.g. Linux kernel version (6.1 vs. 5.15 in Android 14 & 13, respectively) and the boot firmware that matches the kernel version on my releases. I know that some of the options in your screenshot (e.g. over_voltage) are deprecated with recent Pi firmware.

I can't find any documentation about the firmware update changelogs but the results haven't changed in either Android 13 or 14. PiOS is on kernel 6.1 but the config.txt is in /boot/firmware now.
