drm/msm: Remove obsolete perf infrastructure

2026-05-29T14:07:27+00:00

Outside of a3xx, this was never really used. And it low-key gets in the way of the new perfcntr support (or at least it is confusing to have two things called "perf"). So lets remove it. This drops the "perf" debugfs file. But these days, nvtop is a better option. (Plus perfetto for newer gens.)

drm/msm/a8xx: Preemption support for A840

2026-03-31T20:47:30+00:00

The programing sequence related to preemption is unchanged from A7x. But there is some code churn due to register shuffling in A8x. So, split out the common code into a header file for code sharing and add/update additional changes required to support preemption feature on A8x GPUs. Finally, enable the preemption quirk in A840's catalog to enable this feature.

drm/msm/dpu: Add Kaanapali SSPP sub-block support

2026-01-21T00:07:23+00:00

Add support for Kaanapali platform SSPP sub-blocks, which introduce structural changes including register additions, removals, and relocations. Add the new common and rectangle blocks, and update register definitions and handling to ensure compatibility with DPU v13.0.

drm/msm/adreno: Introduce A8x GPU Support

2025-11-18T17:04:01+00:00

A8x is the next generation of Adreno GPUs, featuring a significant hardware design change. A major update to the design is the introduction of Slice architecture. Slices are sort of mini-GPUs within the GPU which are more independent in processing Graphics and compute workloads. Also, in addition to the BV and BR pipe we saw in A7x, CP has more concurrency with additional pipes. From a software interface perspective, these changes have a significant impact on the KMD side. First, the GPU register space has been extensively reorganized. Second, to avoid a register space explosion caused by the new slice architecture and additional pipes, many registers are now virtualized, instead of duplicated as in A7x. KMD must configure an aperture register with the appropriate slice and pipe ID before accessing these virtualized registers.

drm/msm: make it possible to disable KMS-related code.

2025-07-05T14:13:35+00:00

If the Adreno device is used in a headless mode, there is no need to build all KMS components. Build corresponding parts conditionally, only selecting them if modeset support is actually required.
