drm/ttm: make ttm_bo_unpin more defensive

drm/ttm: Warn on pinning without holding a reference

2021-03-24T10:54:10Z

[ Upstream commit 57fcd550eb15bce14a7154736379dfd4ed60ae81 ] Not technically a problem for ttm, but very likely a driver bug and pretty big time confusing for reviewing code. So warn about it, both at cleanup time (so we catch these for sure) and at pin/unpin time (so we know who's the culprit).

drm/dp/mst: Export drm_dp_get_vc_payload_bw()

2021-02-02T15:31:37Z

This function will be needed by the next patch where the driver calculates the BW based on driver specific parameters, so export it. At the same time sanitize the function params, passing the more natural link rate instead of the encoding of the same rate. v2: - Fix function documentation.

drm/fb-helper: Rename dirty worker to damage worker

2020-11-24T08:27:55Z

The dirty worker handles all damage updates, instead of just calling the framebuffer's dirty callback. Rename it to damage worker. Also rename related variables accordingly.

drm/shmem-helper: Use cached mappings by default

2020-11-24T08:10:21Z

SHMEM-buffer backing storage is allocated from system memory; which is typically cachable. The default mode for SHMEM objects is writecombine though. Unify SHMEM semantics by defaulting to cached mappings. The exception is pages imported via dma-buf. DMA memory is usually not cached. DRM drivers that require write-combined mappings set the map_wc flag in struct drm_gem_shmem_object to true. This currently affects lima, panfrost and v3d. The drivers mgag200, udl, virtio and vkms continue to use default shmem mappings. The drivers cirrus and gm12u320 change caching flags. Both used writecombine and now switch over to shmem defaults. Both drivers use SHMEM objects as shadow buffers for internal video memory, so cached mappings will not affect them negatively. v3: * set value of shmem pointer before dereferencing it in __drm_gem_shmem_create() (Dan, kernel test robot) v2: * recreate patch on top of latest SHMEM helpers * update lima, panfrost, v3d to select writecombine (Daniel, Rob) Signed-off-by: Thomas Zimmermann Acked-by: Maxime Ripard Link: https://patchwork.freedesktop.org/patch/msgid/20201117133156.26822-2-tzimmermann@suse.de

drm: Pass the full state to connectors atomic functions

2020-11-20T11:23:53Z

The current atomic helpers have either their object state being passed as an argument or the full atomic state. The former is the pattern that was done at first, before switching to the latter for new hooks or when it was needed. Now that the CRTCs have been converted, let's move forward with the connectors to provide a consistent interface. The conversion was done using the coccinelle script below, and built tested on all the drivers. @@ identifier connector, connector_state; @@ struct drm_connector_helper_funcs { ... struct drm_encoder* (*atomic_best_encoder)(struct drm_connector *connector, - struct drm_connector_state *connector_state); + struct drm_atomic_state *state); ... } @@ identifier connector, connector_state; @@ struct drm_connector_helper_funcs { ... void (*atomic_commit)(struct drm_connector *connector, - struct drm_connector_state *connector_state); + struct drm_atomic_state *state); ... } @@ struct drm_connector_helper_funcs *FUNCS; identifier state; identifier connector, connector_state; identifier f; @@ f(..., struct drm_atomic_state *state, ...) { <+... - FUNCS->atomic_commit(connector, connector_state); + FUNCS->atomic_commit(connector, state); ...+> } @@ struct drm_connector_helper_funcs *FUNCS; identifier state; identifier connector, connector_state; identifier var, f; @@ f(struct drm_atomic_state *state, ...) { <+... - var = FUNCS->atomic_best_encoder(connector, connector_state); + var = FUNCS->atomic_best_encoder(connector, state); ...+> } @ connector_atomic_func @ identifier helpers; identifier func; @@ ( static struct drm_connector_helper_funcs helpers = { ..., .atomic_best_encoder = func, ..., }; | static struct drm_connector_helper_funcs helpers = { ..., .atomic_commit = func, ..., }; ) @@ identifier connector_atomic_func.func; identifier connector; symbol state; @@ func(struct drm_connector *connector, - struct drm_connector_state *state + struct drm_connector_state *connector_state ) { ... - state + connector_state ... } @ ignores_state @ identifier connector_atomic_func.func; identifier connector, connector_state; @@ func(struct drm_connector *connector, struct drm_connector_state *connector_state) { ... when != connector_state } @ adds_state depends on connector_atomic_func && !ignores_state @ identifier connector_atomic_func.func; identifier connector, connector_state; @@ func(struct drm_connector *connector, struct drm_connector_state *connector_state) { + struct drm_connector_state *connector_state = drm_atomic_get_new_connector_state(state, connector); ... } @ depends on connector_atomic_func @ identifier connector_atomic_func.func; identifier connector_state; identifier connector; @@ func(struct drm_connector *connector, - struct drm_connector_state *connector_state + struct drm_atomic_state *state ) { ... } @ include depends on adds_state @ @@ #include @ no_include depends on !include && adds_state @ @@ + #include #include Signed-off-by: Maxime Ripard Reviewed-by: Rodrigo Siqueira Reviewed-by: Ville Syrjälä Acked-by: Thomas Zimmermann Acked-by: Harry Wentland Cc: Leo Li Cc: Alex Deucher Cc: "Christian König" Cc: Jani Nikula Cc: Joonas Lahtinen Cc: Rodrigo Vivi Cc: Ben Skeggs Cc: Rodrigo Siqueira Cc: Melissa Wen Cc: Haneen Mohammed Link: https://patchwork.freedesktop.org/patch/msgid/20201118094758.506730-1-maxime@cerno.tech
