Subject: [PATCH v5 0/6] Add support for GPU DDR BW scaling
Date: Mon, 13 Jul 2020 18:11:40 +0530 [thread overview]
Message-ID: <1594644106-22449-1-git-send-email-akhilpo@codeaurora.org> (raw)
This series adds support for GPU DDR bandwidth scaling and is based on the
bindings from Georgi [1]. This is mostly a rebase of Sharat's patches [2] on the
tip of msm-next branch.
Changes from v4:
- Squashed a patch to another one to fix Jonathan's comment
- Add back the pm_runtime_get_if_in_use() check
Changes from v3:
- Rebased on top of Jonathan's patch which adds support for changing gpu freq
through hfi on newer targets
- As suggested by Rob, left the icc_path intact for pre-a6xx GPUs
