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

2025-07-05T14:13:35Z

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.

drm/msm: move KMS driver data to msm_kms

2025-07-05T14:13:35Z

Data for HDMI, DSI and DP blocks only makes sense for the KMS parts of the driver. Move corresponding data pointers from struct msm_drm_private to struct msm_kms.

drm/msm: move helper calls to msm_kms.c

Extract two more KMS-related codepieces to msm_kms.c, removing last pieces of KMS code from msm_drv.c. Reviewed-by: Abhinav Kumar Signed-off-by: Dmitry Baryshkov Patchwork: https://patchwork.freedesktop.org/patch/662574/ Signed-off-by: Rob Clark

drm/msm: Use drm_gpuvm types more

2025-07-05T00:48:35Z

Most of the driver code doesn't need to reach in to msm specific fields, so just use the drm_gpuvm/drm_gpuva types directly. This should hopefully improve commonality with other drivers and make the code easier to understand.

drm/msm: Rename msm_gem_address_space -> msm_gem_vm

2025-07-04T18:09:44Z

Re-aligning naming to better match drm_gpuvm terminology will make things less confusing at the end of the drm_gpuvm conversion. This is just rename churn, no functional change.

drm/msm/dpu: don't set crtc_state->mode_changed from atomic_check()

2025-03-05T02:33:33Z

The MSM driver uses drm_atomic_helper_check() which mandates that none of the atomic_check() callbacks toggles crtc_state->mode_changed. Perform corresponding check before calling the drm_atomic_helper_check() function.

drm/msm/dpu: rate limit snapshot capture for mmu faults

2025-02-26T10:15:49Z

There is no recovery mechanism in place yet to recover from mmu faults for DPU. We can only prevent the faults by making sure there is no misconfiguration. Rate-limit the snapshot capture for mmu faults to once per msm_atomic_commit_tail() as that should be sufficient to capture the snapshot for debugging otherwise there will be a lot of DPU snapshots getting captured for the same fault which is redundant and also might affect capturing even one snapshot accurately.

Now as all subdrivers were converted to use common database of formats, drop the get_format() callback and use mdp_get_format() directly.
