Quoting Sasha Levin (2021-03-02 03:55:07)From: AngeloGioacchino Del Regno <[email protected]>[ Upstream commit 785c02eb35009a4be6dbc68f4f7d916e90b7177d ] In some rare occasions, we want to only set the RETAIN_MEM bit, but not the RETAIN_PERIPH one: this is seen on at least SDM630/636/660's GPU-GX GDSC, where unsetting and setting back the RETAIN_PERIPH bit will generate chaos and panics during GPU suspend time (mainly, the chaos is unaligned access). For this reason, introduce a new NO_RET_PERIPH flag to the GDSC driver to address this corner case.Is there a patch that's going to use this in stable trees? On its own this patch doesn't make sense to backport.
Right, I'll also grab a59c16c80bd7 ("clk: qcom: gpucc-msm8998: Add
resets, cxc, fix flags on gpu_gx_gdsc") for 5.10 and 5.11. Thanks!
