2023-12-08drm/atomic-helper: rename drm_atomic_helper_check_wb_encoder_stateDmitry Baryshkov
The drm_atomic_helper_check_wb_encoder_state() function doesn't use encoder for anything other than getting the drm_device instance. The function's description talks about checking the writeback connector state, not the encoder state. Moreover, there is no such thing as an encoder state, encoders generally do not have a state on their own. Rename the function to drm_atomic_helper_check_wb_connector_state() and change arguments to drm_writeback_connector and drm_atomic_state.

2023-12-06drm/atomic-helpers: Invoke end_fb_access while owning plane stateThomas Zimmermann
Invoke drm_plane_helper_funcs.end_fb_access before drm_atomic_helper_commit_hw_done(). The latter function hands over ownership of the plane state to the following commit, which might free it. Releasing resources in end_fb_access then operates on undefined state. This bug has been observed with non-blocking commits when they are being queued up quickly. Here is an example stack trace from the bug report. The plane state has been free'd already, so the pages for drm_gem_fb_vunmap() are gone. Unable to handle kernel paging request at virtual address 0000000100000049 [...] drm_gem_fb_vunmap+0x18/0x74 drm_gem_end_shadow_fb_access+0x1c/0x2c drm_atomic_helper_cleanup_planes+0x58/0xd8 drm_atomic_helper_commit_tail+0x90/0xa0 commit_tail+0x15c/0x188 commit_work+0x14/0x20 Fix this by running end_fb_access immediately after updating all planes in drm_atomic_helper_commit_planes(). The existing clean-up helper drm_atomic_helper_cleanup_planes() now only handles cleanup_fb. For aborted commits, roll back from drm_atomic_helper_prepare_planes() in the new helper drm_atomic_helper_unprepare_planes(). This case is different from regular cleanup, as we have to release the new state; regular cleanup releases the old state. The new helper also invokes cleanup_fb for all planes. The changes mostly involve DRM's atomic helpers. Only two drivers, i915 and nouveau, implement their own commit function. Update them to invoke drm_atomic_helper_unprepare_planes(). Drivers with custom commit_tail function do not require changes. v4: * fix documentation (kernel test robot) v3: * add drm_atomic_helper_unprepare_planes() for rolling back * use correct state for end_fb_access v2: * fix test in drm_atomic_helper_cleanup_planes() Reported-by: Alyssa Ross <hi@alyssa.is> Closes: https://lore.kernel.org/dri-devel/87leazm0ya.fsf@alyssa.is/ Suggested-by: Daniel Vetter <daniel@ffwll.ch> Fixes: 94d879eaf7fb ("drm/atomic-helper: Add {begin,end}_fb_access to plane helpers") Tested-by: Alyssa Ross <hi@alyssa.is> Reviewed-by: Alyssa Ross <hi@alyssa.is> Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Cc: <stable@vger.kernel.org> # v6.2+ Link: https://patchwork.freedesktop.org/patch/msgid/20231204083247.22006-1-tzimmermann@suse.de

2020-01-31drm/bridge: Add the necessary bits to support bus format negotiationBoris Brezillon
drm_bridge_state is extended to describe the input and output bus configurations. These bus configurations are exposed through the drm_bus_cfg struct which encodes the configuration of a physical bus between two components in an output pipeline, usually between two bridges, an encoder and a bridge, or a bridge and a connector. The bus configuration is stored in drm_bridge_state separately for the input and output buses, as seen from the point of view of each bridge. The bus configuration of a bridge output is usually identical to the configuration of the next bridge's input, but may differ if the signals are modified between the two bridges, for instance by an inverter on the board. The input and output configurations of a bridge may differ if the bridge modifies the signals internally, for instance by performing format conversion, or*modifying signals polarities. Bus format negotiation is automated by the core, drivers just have to implement the ->atomic_get_{output,input}_bus_fmts() hooks if they want to take part to this negotiation. Negotiation happens in reverse order, starting from the last element of the chain (the one directly connected to the display) up to the first element of the chain (the one connected to the encoder). During this negotiation all supported formats are tested until we find one that works, meaning that the formats array should be in decreasing preference order (assuming the driver has a preference order). Note that the bus format negotiation works even if some elements in the chain don't implement the ->atomic_get_{output,input}_bus_fmts() hooks. In that case, the core advertises only MEDIA_BUS_FMT_FIXED and lets the previous bridge element decide what to do (most of the time, bridge drivers will pick a default bus format or extract this piece of information from somewhere else, like a FW property). v10: * Add changelog to the commit message v9: * No changes v8: * Fix a test in drm_atomic_bridge_chain_select_bus_fmts() (Reported by Jonas) v7: * Adapt the code to deal with the fact that not all bridges in the chain have a bridge state v5 -> v6: * No changes v4: * Enhance the doc * Fix typos * Rename some parameters/fields * Reword the commit message v3: * Fix the commit message (Reported by Laurent) * Document the fact that bus formats should not be directly modified by drivers (Suggested by Laurent) * Document the fact that format order matters (Suggested by Laurent) * Propagate bus flags by default * Document the fact that drivers can tweak bus flags if needed * Let ->atomic_get_{output,input}_bus_fmts() allocate the bus format array (Suggested by Laurent) * Add a drm_atomic_helper_bridge_propagate_bus_fmt() * Mandate that bridge drivers return accurate input_fmts even if they are known to be the first element in the bridge chain v2: * Rework things to support more complex use cases Signed-off-by: Boris Brezillon <boris.brezillon@collabora.com> Signed-off-by: Neil Armstrong <narmstrong@baylibre.com> [narmstrong: fixed doc in include/drm/drm_bridge.h:69 fmt->format] Reviewed-by: Jernej Skrabec <jernej.skrabec@siol.net> Tested-by: Jonas Karlman <jonas@kwiboo.se> Link: https://patchwork.freedesktop.org/patch/msgid/20200128135514.108171-7-boris.brezillon@collabora.com

2018-07-07drm/crtc: Add a generic infrastructure to fake VBLANK eventsBoris Brezillon
In some cases CRTCs are active but are not able to generating events, at least not at every frame at it's expected to. This is typically the case when the CRTC is feeding a writeback connector that has no job queued. In this situation the CRTC is usually stopped until a new job is queued, and this can lead to timeouts when part of the pipeline is updated but no new jobs are queued to the active writeback connector. In order to solve that, we add a ->no_vblank flag to drm_crtc_state and ask the CRTC drivers to set it to true when they know they're not able to generate VBLANK events. The core drm_atomic_helper_fake_vblank() helper can then be used to fake VBLANKs at commit time.

2017-07-03drm/atomic: initial support for asynchronous plane updateGustavo Padovan
In some cases, like cursor updates, it is interesting to update the plane in an asynchronous fashion to avoid big delays. The current queued update could be still waiting for a fence to signal and thus block any subsequent update until its scan out. In cases like this if we update the cursor synchronously through the atomic API it will cause significant delays that would even be noticed by the final user. This patch creates a fast path to jump ahead the current queued state and do single planes updates without going through all atomic steps in drm_atomic_helper_commit(). We take this path for legacy cursor updates. For now only single plane updates are supported, but we plan to support multiple planes updates and async PageFlips through this interface as well in the near future. v6: - move check code to drm_atomic_helper.c (Daniel Vetter) v5: - improve comments (Eric Anholt) v4: - fix state->crtc NULL check (Archit Taneja) v3: - fix iteration on the wrong crtc state - put back code to forbid updates if there is a queued update for the same plane (Ville Syrjälä) - move size checks back to drivers (Ville Syrjälä) - move ASYNC_UPDATE flag addition to its own patch (Ville Syrjälä) v2: - allow updates even if there is a queued update for the same plane. - fixes on the documentation (Emil Velikov) - unconditionally call ->atomic_async_update (Emil Velikov) - check for ->atomic_async_update earlier (Daniel Vetter) - make ->atomic_async_check() the last step (Daniel Vetter) - add ASYNC_UPDATE flag (Eric Anholt) - update state in core after ->atomic_async_update (Eric Anholt) - update docs (Eric Anholt) Cc: Daniel Vetter <daniel.vetter@intel.com> Cc: Rob Clark <robdclark@gmail.com> Cc: Eric Anholt <eric@anholt.net> Signed-off-by: Gustavo Padovan <gustavo.padovan@collabora.com> Reviewed-by: Archit Taneja <architt@codeaurora.org> (v5) Acked-by: Eric Anholt <eric@anholt.net> (v5) Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: http://patchwork.freedesktop.org/patch/msgid/20170630180322.29007-2-gustavo@padovan.org

2017-03-27drm/atomic: Introduce drm_atomic_helper_shutdownDaniel Vetter
The trouble here is that it does multiple atomic commits under one drm_modeset_lock_all, which breaks the behind-the-scenes acquire context magic that function pulls off. It's much better to have one overall atomic commit. That we still have multiple atomic commits prevents us from adding some pretty useful debug checks to the atomic machinery. Hence it is really a bad idea to call the legacy drm_crtc_force_disable_all() function. There's 2 atomic drivers using this still, nouveau and tinydrm. To fix this, introduce a new drm_atomic_helper_shutdown() by extracting the code from i915. While at it improve kernel-doc and catch future offenders by sprinkling a WARN_ON into the legacy function. We should probably move those into the legacy modeset helpers, too ... v2: Make it compile on arm drivers too (Noralf). v3: Correct kerneldoc to point at _disable_all().

Drivers may set the NO_DISABLE_AFTER_MODESET flag in the 'flags' parameter of the helper drm_atomic_helper_commit_planes() if the relevant display controllers(e.g., IPUv3 for imx-drm) require to disable a CRTC's planes when the CRTC is disabled. The helper would skip the ->atomic_disable call for a plane if the CRTC of the old plane state needs a modesetting operation. Of course, the drivers need to disable the planes in their CRTC disable callbacks since no one else would do that.

2016-08-29drm/atomic-helper: Disable appropriate planes in disable_planes_on_crtc()Liu Ying
Currently, the helper drm_atomic_helper_disable_planes_on_crtc() calls ->atomic_disable for all planes _to be_ enabled on a particular CRTC. This is obviously wrong for those planes which are not scanning out frames when the helper is called. Instead, it's sane to disable active planes of old_crtc_state in the helper.

2016-08-16drm/kms-helpers: Extract drm_modeset_helper.[hc]Daniel Vetter
While reviewing docs I spotted that we have a few functions that really just don't fit into their containing helper library section. Extract them and shovel them all into a new library for random one-off aux stuff. v2: Remove wrongly added files for real.
