[PATCH RFC v2 0/6] Add support for Adreno 810 GPU
From: Alexander Koskovich
Date: Thu Apr 02 2026 - 19:09:10 EST
Adreno 810 is present in the Milos SoC and is the first GPU to be released in
the A8x family.
Note that the OPP table is limited to 1050MHz to start with as the only Milos
device I have is limited to that speed in GPU_CC_FREQ_LIMIT_VAL.
This series is marked as RFC because it depends on a couple other in review
series, batch 2 for A8x [1] and the GXCLKCTL block for Milos [2].
There is also currently an issue on Milos with gx_clkctl_gx_gdsc being stuck on
during runtime PM [3]. The proper fix is to only toggle the GX GDSC during GMU
recovery, as the firmware manages it in all other cases. This is the same issue
seen on SM8750 and is being worked on by Qualcomm. Right now I am just working
around this locally by not collapsing the GX GDSC during runtime suspend.
