drm: Analog TV Improvements
|
expand
|
Hi, Here's a series aiming at improving the command line named modes support, and more importantly how we deal with all the analog TV variants. The named modes support were initially introduced to allow to specify the analog TV mode to be used. However, this was causing multiple issues: * The mode name parsed on the command line was passed directly to the driver, which had to figure out which mode it was suppose to match; * Figuring that out wasn't really easy, since the video= argument or what the userspace might not even have a name in the first place, but instead could have passed a mode with the same timings; * The fallback to matching on the timings was mostly working as long as we were supporting one 525 lines (most likely NSTC) and one 625 lines (PAL), but couldn't differentiate between two modes with the same timings (NTSC vs PAL-M vs NSTC-J for example); * There was also some overlap with the tv mode property registered by drm_mode_create_tv_properties(), but named modes weren't interacting with that property at all. * Even though that property was generic, its possible values were specific to each drivers, which made some generic support difficult. Thus, I chose to tackle in multiple steps: * A new TV mode property was introduced, with generic values, each driver reporting through a bitmask what standard it supports to the userspace; * This option was added to the command line parsing code to be able to specify it on the kernel command line, and new atomic_check and reset helpers were created to integrate properly into atomic KMS; * The named mode parsing code is now creating a proper display mode for the given named mode, and the TV standard will thus be part of the connector state; * Two drivers were converted and tested for now (vc4 and sun4i), with some backward compatibility code to translate the old TV mode to the new TV mode; Unit tests were created along the way. One can switch from NTSC to PAL now using (on vc4) modetest -M vc4 -s 53:720x480i -w 53:'TV mode':1 # NTSC modetest -M vc4 -s 53:720x576i -w 53:'TV mode':4 # PAL Let me know what you think, Maxime To: David Airlie <airlied@linux.ie> To: Daniel Vetter <daniel@ffwll.ch> To: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> To: Maxime Ripard <mripard@kernel.org> To: Thomas Zimmermann <tzimmermann@suse.de> To: Emma Anholt <emma@anholt.net> To: Jani Nikula <jani.nikula@linux.intel.com> To: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> To: Rodrigo Vivi <rodrigo.vivi@intel.com> To: Tvrtko Ursulin <tvrtko.ursulin@linux.intel.com> To: Ben Skeggs <bskeggs@redhat.com> To: Karol Herbst <kherbst@redhat.com> To: Lyude Paul <lyude@redhat.com> To: Chen-Yu Tsai <wens@csie.org> To: Jernej Skrabec <jernej.skrabec@gmail.com> To: Samuel Holland <samuel@sholland.org> Cc: Geert Uytterhoeven <geert@linux-m68k.org> Cc: Mateusz Kwiatkowski <kfyatek+publicgit@gmail.com> Cc: "Noralf Trønnes" <noralf@tronnes.org> Cc: Dave Stevenson <dave.stevenson@raspberrypi.com> Cc: Dom Cobley <dom@raspberrypi.com> Cc: Phil Elwell <phil@raspberrypi.com> Cc: <dri-devel@lists.freedesktop.org> Cc: linux-kernel@vger.kernel.org Cc: intel-gfx@lists.freedesktop.org Cc: nouveau@lists.freedesktop.org Cc: linux-arm-kernel@lists.infradead.org Cc: linux-sunxi@lists.linux.dev Cc: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Maxime Ripard <maxime@cerno.tech> --- Changes in v5: -
