Subject: [PATCH v7 0/7] qcom: add OCMEM support
Date: Fri, 23 Aug 2019 05:16:30 -0700
Message-ID: <20190823121637.5861-1-masneyb@onstation.org> (raw)

This patch series adds support for Qualcomm's On Chip MEMory (OCMEM)
that is needed in order to support some a3xx and a4xx-based GPUs
upstream. This is based on Rob Clark's patch series that he submitted
in October 2015 and I am resubmitting updated patches with his
permission. See the individual patches for the changelog.

This was tested with the GPU on a LG Nexus 5 (hammerhead) phone and
this will work on other msm8974-based systems. For a summary of what
currently works upstream on the Nexus 5, see my status page at
https://masneyb.github.io/nexus-5-upstream/.

Changes since v6:
- link to gmu-sram child node in device tree
- add ranges property to ocmem example in adreno GMU example (patch 2)
  to match bindings in patch 1

See individual patches for changelogs for previous versions.
