* drm: Include <linux/of.h> where neededThomas Zimmermann2023-01-131-2/+3
| | | | | | | | | | | | | | | | | | | Include <linux/of.h> in source files that need it. Some of DRM's source code gets OF header via drm_crtc_helper.h and <linux/fb.h>, which can leed to unnecessary recompilation. In drm_modes.c, add a comment on the reason for still including <linux/fb.h>. The header file is required to get KHZ2PICOS(). The macro is part of the UAPI headers, so it cannot be moved to a less prominent location. v2: * include <linux/of.h> in komeda_drv.c (kernel test robot) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Acked-by: Liviu Dudau <liviu.dudau@arm.com> # komeda Acked-by: Maxime Ripard <maxime@cerno.tech> Link: https://patchwork.freedesktop.org/patch/msgid/20230111130206.29974-3-tzimmermann@suse.de

* drm/modes: Properly generate a drm_display_mode from a named modeMaxime Ripard2022-11-241-1/+28
| | | | | | | | | | | | | | | | | | | | | | The framework will get the drm_display_mode from the drm_cmdline_mode it got by parsing the video command line argument by calling drm_connector_pick_cmdline_mode(). The heavy lifting will then be done by the drm_mode_create_from_cmdline_mode() function. In the case of the named modes though, there's no real code to make that translation and we rely on the drivers to guess which actual display mode we meant. Let's modify drm_mode_create_from_cmdline_mode() to properly generate the drm_display_mode we mean when passing a named mode.

| | | | | | | | | | | | | | Our new tv mode option allows to specify the TV mode from a property.

* drm/modes: Add a function to generate analog display modesMaxime Ripard2022-11-241-0/+476
| | | | | | | | | | | | | | | | | | | Multiple drivers (meson, vc4, sun4i) define analog TV 525-lines and 625-lines modes in their drivers. Since those modes are fairly standard, and that we'll need to use them in more places in the future, it makes sense to move their definition into the core framework. However, analog display usually have fairly loose timings requirements, the only discrete parameters being the total number of lines and pixel clock frequency. Thus, we created a function that will create a display mode from the standard, the pixel frequency and the active area.

* drm/modes: Fill drm_cmdline mode from named modesMaxime Ripard2022-11-151-2/+16
| | | | | | | | | | | | | | | The current code to deal with named modes will only set the mode name, and then it's up to drivers to try to match that name to whatever mode or configuration they see fit. The plan is to remove that need and move the named mode handling out of drivers and into the core, and only rely on modes and properties.

| | | | | | | | | | | | | | | It is fairly common for named video modes to contain dashes (e.g. "tt-mid" on Atari, "dblntsc-ff" on Amiga). Currently such mode names are not recognized, as the dash is considered to be a separator between mode name and bpp. Fix this by skipping any dashes that are not followed immediately by a digit when looking for the separator.

| | | | | | | | | | | | | | | | | 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.

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

| | | | | | | | | | | | | | | | | | | | | | 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).
