2020-09-15drm/msm: a6xx: Use WHERE_AM_I for eligible targetsJordan Crouse
Support the WHERE_AM_I opcode for the A618, A630 and A640 GPUs if the microcode supports it. The WHERE_AM_I opcode allows the RPTR shadow to be updated in priviliged memory which protects the shadow from being read or written from user submissions. A650 already supports extended APRIV have built in hardware support for to access privilged memory from the CP and can go back to using the hardware RPTR shadow feature.

2020-09-12drm/msm/a6xx: Add support for per-instance pagetablesJordan Crouse
Add support for using per-instance pagetables if all the dependencies are available. Signed-off-by: Jordan Crouse <jcrouse@codeaurora.org> Signed-off-by: Rob Clark <robdclark@chromium.org> Reviewed-by: Akhil P Oommen <akhilpo@codeaurora.org>
2020-07-31drm: msm: a6xx: send opp instead of a frequencySharat Masetty
This patch changes the plumbing to send the devfreq recommended opp rather than the frequency. Also consolidate and rearrange the code in a6xx to set the GPU frequency and the icc vote in preparation for the upcoming changes for GPU->DDR scaling votes.

2020-01-02drm: msm: a6xx: Add support for A618Sharat Masetty
This patch adds support for enabling Graphics Bus Interface(GBIF) used in multiple A6xx series chipets. Also makes changes to the PDC/RSC sequencing specifically required for A618. This is needed for proper interfacing with RPMH. Signed-off-by: Sharat Masetty <smasetty@codeaurora.org> Signed-off-by: Rob Clark <robdclark@chromium.org>
2019-05-24drm/msm/a6xx: Rename a6xx_gmu_probe to a6xx_gmu_initSean Paul
This rename makes it more clear that everything initialized in the _init function must be cleaned up in a6xx_gmu_remove. This will hopefully dissuade people from using device managed resources (for reasons laid out in the previous patch).

2019-04-19drm/msm/a6xx: Make GMU reset usefulJordan Crouse
Now that the GX domain is sorted we can wire up a working GMU reset. IF a GMU hang was detected then try to forcefully shut down the GMU in the power down sequence which should ensure that it can recover normally on the next power up.

2018-12-11drm/msm/a6xx: Add a6xx gpu stateJordan Crouse
Add support for gathering and dumping the a6xx GPU state including registers, GMU registers, indexed registers, shader blocks, context clusters and debugbus. v2: Fix bugs discovered by Sharat Masetty Signed-off-by: Jordan Crouse <jcrouse@codeaurora.org> Signed-off-by: Rob Clark <robdclark@gmail.com>
2018-10-04drm/msm/a6xx: Add devfreq support for a6xxSharat Masetty
Implement routines to estimate GPU busy time and fetching the current frequency for the polling interval. This is required by the devfreq framework which recommends a frequency change if needed. The driver code then tries to set this new frequency on the GPU by sending an Out Of Band(OOB) request to the GMU.

2018-08-10drm/msm: Add A6XX device supportJordan Crouse
Add support for the A6XX family of Adreno GPUs. The biggest addition is the GMU (Graphics Management Unit) which takes over most of the power management of the GPU itself but in a ironic twist of fate needs a goodly amount of management itself. Add support for the A6XX core code, the GMU and the HFI (hardware firmware interface) queue that the CPU uses to communicate with the GMU.
