Subject: [PATCH v4 0/7] Add support for GPU DDR BW scaling
Date: Fri, 10 Jul 2020 01:30:20 +0530 [thread overview]
Message-ID: <1594324828-9571-1-git-send-email-akhilpo@codeaurora.org> (raw)
This is mostly a rebase of Sharat's patches [1] on the tip of msm-next branch.
Changes compared to v3:
1. Rebased on top of Jonathan's patch which adds support for changing
gpu freq through hfi on newer targets. Created patch 1 to make
this the generic approach of setting gpu freq on newer targets.
2. As suggested by Rob, left the icc_path intact for pre-a6xx
GPUs.
As mentioned in [1], these patches have dependency on Georgi's series from
opp/linux-next [2] and also Sibi's patch which adds a helper function to
set and clear ddr bandwidth vote [2].
