drm: omapdrm: reduce clang stack usage

2025-06-12T18:29:52Z

The thread sanitizer makes the stack usage explode from extra variable spills in dispc_runtime_resume: drivers/gpu/drm/omapdrm/dss/dispc.c:4735:27: error: stack frame size (1824) exceeds limit (1280) in 'dispc_runtime_resume' [-Werror,-Wframe-larger-than] I could not figure out what exactly is going on here, but I see that whenever dispc_restore_context() is not inlined, that function and its caller shrink below 900 bytes combined of stack usage.

drm/omap: dss: venc: convert to devm_drm_bridge_alloc() API

2025-05-21T11:40:09Z

This is the new API for allocating DRM bridges. Switching from a non-devm to a devm allocation allows removing the kfree() in the remove function and in the probe error management code, and as a consequence to simplify the code flow by removing now unnecessary gotos.

timer_delete[_sync]() replaces del_timer[_sync](). Convert the whole tree over and remove the historical wrapper inlines. Conversion was done with coccinelle plus manual fixups where necessary. Signed-off-by: Thomas Gleixner Signed-off-by: Ingo Molnar

drm/bridge: Add encoder parameter to drm_bridge_funcs.attach

2025-03-20T13:45:38Z

The drm_bridge structure contains an encoder pointer that is widely used by bridge drivers. This pattern is largely documented as deprecated in other KMS entities for atomic drivers. However, one of the main use of that pointer is done in attach to just call drm_bridge_attach on the next bridge to add it to the bridge list. While this dereferences the bridge->encoder pointer, it's effectively the same encoder the bridge was being attached to. We can make it more explicit by adding the encoder the bridge is attached to to the list of attach parameters. This also removes the need to dereference bridge->encoder in most drivers.
