drm/selftests: Add command line parser selftests The command line parser is pretty tough to get right and very error prone, so let's add a selftest to try to catch any regression.

drm/modes: Make sure to parse valid rotation value from cmdline A rotation value should have exactly one rotation angle. At the moment there is no validation for this when parsing video= parameters from the command line. This causes problems later on when we try to combine the command line rotation with the panel orientation. To make sure that we generate a valid rotation value: - Set DRM_MODE_ROTATE_0 by default (if no rotate= option is set) - Validate that there is exactly one rotation angle set (i.e. specifying the rotate= option multiple times is invalid) Signed-off-by: Stephan Gerhold <stephan@gerhold.net> Signed-off-by: Maxime Ripard <maxime@cerno.tech> Link: https://patchwork.freedesktop.org/patch/msgid/20200117153429.54700-2-stephan@gerhold.net

drm/modes: parse_cmdline: Stop parsing extras after bpp / refresh at ', ' Before this commit it was impossible to add an extra mode argument after a bpp or refresh specifier, combined with an option, e.g. video=HDMI-1:720x480-24e,rotate=180 would not work, either the "e" to force enable would need to be dropped or the ",rotate=180", otherwise the mode_option would not be accepted. This commit fixes this by fixing the length calculation if extras_ptr is set to stop the extra parsing at the start of the options (stop at the ',' options_ptr points to).

drm/modes: parse_cmdline: Accept extras directly after mode combined with options Before this commit it was impossible to combine an extra mode argument specified directly after the resolution with an option, e.g. video=HDMI-1:720x480e,rotate=180 would not work, either the "e" to force enable would need to be dropped or the ",rotate=180", otherwise the mode_option would not be accepted. This commit fixes this by setting parse_extras to true in this case, so that drm_mode_parse_cmdline_res_mode() parses the extra arguments directly after the resolution.

cmdline_test(drm_cmdline_test_extra_and_option)
drm/modes: parse_cmdline: Allow specifying stand-alone options Some options which can be specified on the commandline, such as margin_right=..., margin_left=..., etc. are applied not only to the specified mode, but to all modes. As such it would be nice if the user can simply say e.g. video=HDMI-1:margin_right=14,margin_left=24,margin_bottom=36,margin_top=42 This commit refactors drm_mode_parse_command_line_for_connector() to add support for this, and as a nice side effect also cleans up the function a bit.

drm/modes: parse_cmdline: Add support for specifying panel_orientation (v2) Sometimes we want to override a connector's panel_orientation from the kernel commandline. Either for testing and for special cases, e.g. a kiosk like setup which uses a TV mounted in portrait mode. Users can already specify a "rotate" option through a video= kernel cmdline option. But that only supports 0/180 degrees (see drm_client_modeset TODO) and only works for in kernel modeset clients, not for userspace kms users. The "panel-orientation" connector property OTOH does support 90/270 degrees as it leaves dealing with the rotation up to userspace and this does work for userspace kms clients (at least those which support this property).
