Hi, The proprietary stack for the RaspberryPi allows for a number of video parameters widely used by their users, but yet don't have any equivalents in the mainline kernel.
Those options are detailed here: https://www.raspberrypi.org/documentation/configuration/config-txt/video.md While not all of them are desirable to have in the mainline kernel, some of them still have value, such as properties to initialise the overscan or rotation parameters, or the one to deal with broken displays. This series is an attempt to support those, and is based on a rewrite of the command line parser I did a couple of years ago that never reached upstream (due to a lack of time on my side). While this parser was initially made to deal with named modes (in order to support TV modes), it also allowed to extend it more easily, which is why it's resurrected. Since a change of the command line parser can pretty easily get things wrong and introduce regressions, I also worked with a number of unit tests that you can find here: http://code.bulix.org/tpo7dg-607264?raw Eventually, I guess those tests should be part of the kernel somewhere, but I haven't found a suitable place for them to be included yet. Let me know what you think, Maxime Maxime Ripard (7): drm/vc4: hdmi: Check that the monitor supports HDMI audio drm/edid: Allow to ignore the audio EDID data drm/edid: Allow to ignore the HDMI monitor mode drm/modes: Rewrite the command line parser drm/modes: Support modes names on the command line drm/modes: Allow to specify rotation and reflection on the commandline drm/modes: Parse overscan properties drivers/gpu/drm/drm_connector.c | 3 +- drivers/gpu/drm/drm_edid.c | 16 +- drivers/gpu/drm/drm_fb_helper.c | 55 ++++- drivers/gpu/drm/drm_modes.c | 441 ++++++++++++++++++++++++--------- drivers/gpu/drm/vc4/vc4_hdmi.c | 6 +- include/drm/drm_connector.h | 3 +- 6 files changed, 408 insertions(+), 116 deletions(-) base-commit: e179d8e074e05a913a0915ae3c4b82f1434d9f4e -- git-series 0.9.1 _______________________________________________ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel
