2024-06-24drm/panic: Add support for drawing a monochrome graphical logoGeert Uytterhoeven
Re-use the existing support for boot-up logos to draw a monochrome graphical logo in the DRM panic handler. When no suitable graphical logo is available, the code falls back to the ASCII art penguin logo. Note that all graphical boot-up logos are freed during late kernel initialization, hence a copy must be made for later use.

When CONFIG_FONTS ("Select compiled-in fonts") is not enabled, the user should not be asked about any fonts. However, when CONFIG_DRM_PANIC is enabled, the user is still asked about the Sparc console 12x22 and Terminus 16x32 fonts. Fix this by moving the "|| DRM_PANIC" to where it belongs.

No implementations of drm_plane_helper_funcs.get_scanout_buffer() fill in the optional drm_scanout_buffer.set_pixel() member.

2024-06-20drm/ttm/tests: Let ttm_bo_test consider different ww_mutex implementation.Sebastian Andrzej Siewior
PREEMPT_RT has a different locking implementation for ww_mutex. The base mutex of struct ww_mutex is declared as struct WW_MUTEX_BASE. The latter is defined as `mutex' for non-PREEMPT_RT builds and `rt_mutex' for PREEMPT_RT builds. Using mutex_lock() directly on the base mutex in ttm_bo_reserve_deadlock() leads to compile error on PREEMPT_RT. The locking-selftest has its own defines to deal with this and it is probably best to defines the needed one within the test program since their usefulness is limited outside of well known selftests. Provide ww_mutex_base_lock() which points to the correct function for PREEMPT_RT and non-PREEMPT_RT builds.

2024-06-19drm: bridge: simple-bridge: use devm_drm_bridge_add in probeMarc Gonzalez
simple_bridge_probe() calls drm_bridge_add() Thus, drm_bridge_remove() must be called in the remove() callback. If we call devm_drm_bridge_add() instead, then drm_bridge_remove() will be called automatically at device release, and the remove() callback is no longer required.

2024-06-18drm/panic: depends on !VT_CONSOLEJocelyn Falempe
The race condition between fbcon and drm_panic can only occurs if VT_CONSOLE is set. So update drm_panic dependency accordingly. This will make it easier for Linux distributions to enable drm_panic by disabling VT_CONSOLE, and keeping fbcon terminal. The only drawback is that fbcon won't display the boot kmsg, so it should rely on userspace to do that. At least plymouth already handle this case with https://gitlab.freedesktop.org/plymouth/plymouth/-/merge_requests/224 Suggested-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Jocelyn Falempe <jfalempe@redhat.com> Reviewed-by: Javier Martinez Canillas <javierm@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240613154041.325964-1-jfalempe@redhat.com

Add this as a value for enum_drm_connector_tv_mode, represented by the string "Mono", to generate video with no colour encoding or bursts. Define it to have no pedestal (since only NTSC-M calls for a pedestal). Change default mode creation to acommodate the new tv_mode value which comprises both 525-line and 625-line formats.

2024-06-17drm: zynqmp_kms: Fix AUX bus not getting unregisteredSean Anderson
drm_encoder_cleanup is responsible for calling drm_bridge_detach for each bridge attached to the encoder. zynqmp_dp_bridge_detach is in turn responsible for unregistering the AUX bus. However, we never ended up calling drm_encoder_cleanup in the remove or error paths, so the AUX bus would stick around after the rest of the driver had been removed. I don't really understand why drm_mode_config_cleanup doesn't call drm_encoder_cleanup for us. It will call destroy (which for simple_encoder is drm_encoder_cleanup) on encoders in the mode_config's encoder_list. Should drm_encoder_cleanup get called before or after drm_atomic_helper_shutdown?

Unconditionally enable the DPSUB layer in the corresponding atomic plane update callback. Setting the new display mode may require disabling and re-enabling the CRTC. This effectively resets DPSUB to the default state with all layers disabled. The original implementation of the plane atomic update enables the corresponding DPSUB layer only if the framebuffer format has changed. This would leave the layer disabled after switching to a different display mode with the same framebuffer format.
