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.

drm/msm: Extract out syncobj helpers

2025-07-05T00:48:37+00:00

We'll be re-using these for the VM_BIND ioctl. Also, rename a few things in the uapi header to reflect that syncobj use is not specific to the submit ioctl.

drm/msm/dp: drop the msm_dp_catalog module

2025-07-04T13:35:19+00:00

Now as the msm_dp_catalog module became nearly empty, drop it, accessing registers directly from the corresponding submodules.

drm/msm/mdp4: switch LVDS to use drm_bridge/_connector

2025-05-01T22:14:11+00:00

LVDS support in MDP4 driver makes use of drm_connector directly. However LCDC encoder and LVDS connector are wrappers around drm_panel. Switch them to use drm_panel_bridge/drm_bridge_connector. This allows using standard interface for the drm_panel and also inserting additional bridges between encoder and panel.

drm/msm/a6xx: Implement preemption for a7xx targets

2024-10-03T20:21:52+00:00

This patch implements preemption feature for A6xx targets, this allows the GPU to switch to a higher priority ringbuffer if one is ready. A6XX hardware as such supports multiple levels of preemption granularities, ranging from coarse grained(ringbuffer level) to a more fine grained such as draw-call level or a bin boundary level preemption. This patch enables the basic preemption level, with more fine grained preemption support to follow.
