2025-02-06drm/tests: hdmi: Fix recursive lockingMaxime Ripard
The find_preferred_mode() functions takes the mode_config mutex, but due to the order most tests have, is called with the crtc_ww_class_mutex taken. This raises a warning for a circular dependency when running the tests with lockdep. Reorder the tests to call find_preferred_mode before the acquire context has been created to avoid the issue.

2025-02-06drm/tests: hdmi: Reorder DRM entities variables assignmentMaxime Ripard
The tests all deviate slightly in how they assign their local pointers to DRM entities. This makes refactoring pretty difficult, so let's just move the assignment as soon as the entities are allocated.

2025-02-06drm/tests: hdmi: Fix WW_MUTEX_SLOWPATH failuresMaxime Ripard
The light_up_connector helper function in the HDMI infrastructure unit tests uses drm_atomic_set_crtc_for_connector(), but fails when it returns an error. This function can return EDEADLK though if the sequence needs to be restarted, and WW_MUTEX_SLOWPATH is meant to test that we handle it properly. Let's handle EDEADLK and restart the sequence in our tests as well.

A regression was caused by commit e4b5ccd392b9 ("drm/v3d: Ensure job pointer is set to NULL after job completion"), but this commit is not yet in next-fixes, fast-forward it. Note that this recreates Linus merge in 96c84703f1cf ("Merge tag 'drm-next-2025-01-17' of https://gitlab.freedesktop.org/drm/kernel") because I didn't want to backmerge a random point in the merge window.

2025-01-07drm/mst: remove mgr parameter and debug logging from drm_dp_get_vc_payload_bw()Jani Nikula
The struct drm_dp_mst_topology_mgr *mgr parameter is only used for debug logging in case the passed in link rate or lane count are zero. There's no further error checking as such, and the function returns 0. There should be no case where the parameters are zero. The returned value is generally used as a divisor, and if we were hitting this, we'd be seeing division by zero. Just remove the debug logging altogether, along with the mgr parameter, so that the function can be used in non-MST contexts without the topology manager. v2: Also remove drm_dp_mst_helper_tests_init as unnecessary (Imre) Cc: Imre Deak <imre.deak@intel.com> Cc: Lyude Paul <lyude@redhat.com> Reviewed-by: Imre Deak <imre.deak@intel.com> Acked-by: Maxime Ripard <mripard@kernel.org> Acked-by: Thomas Zimmermann <tzimmermann@suse.de> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/72d77e7a7fe69c784e9df048b7e6f250fd7599e4.1735912293.git.jani.nikula@intel.com

2024-05-28drm/connector: hdmi: Add Infoframes generationMaxime Ripard
Infoframes in KMS is usually handled by a bunch of low-level helpers that require quite some boilerplate for drivers. This leads to discrepancies with how drivers generate them, and which are actually sent. Now that we have everything needed to generate them in the HDMI connector state, we can generate them in our common logic so that drivers can simply reuse what we precomputed.

2024-05-28drm/connector: hdmi: Add custom hook to filter TMDS character rateMaxime Ripard
Most of the HDMI controllers have an upper TMDS character rate limit they can't exceed. On "embedded"-grade display controllers, it will typically be lower than what high-grade monitors can provide these days, so drivers will filter the TMDS character rate based on the controller capabilities. To make that easier to handle for drivers, let's provide an optional hook to be implemented by drivers so they can tell the HDMI controller helpers if a given TMDS character rate is reachable for them or not. This will then be useful to figure out the best format and bpc count for a given mode.

2024-05-28drm/connector: hdmi: Calculate TMDS character rateMaxime Ripard
Most HDMI drivers have some code to calculate the TMDS character rate, usually to adjust an internal clock to match what the mode requires. Since the TMDS character rates mostly depends on the resolution, whether we need to repeat pixels or not, the bpc count and the format, we can now derive it from the HDMI connector state that stores all those infos and remove the duplication from drivers.
