struct drm_fb_helper_crtc is now just a wrapper around drm_mode_set so use that directly instead and attach it as a modeset array onto drm_client_dev. drm_fb_helper will use this array to store its modesets which means it will always initialize a drm_client, but it will not register the client (callbacks) unless it's the generic fbdev emulation. Code will later be moved to drm_client, so add code there in a new file drm_client_modeset.c with MIT license to match drm_fb_helper.c. The modeset connector array size is hardcoded for the cloned case to avoid having to pass in a value from the driver. A value of 8 is chosen to err on the safe side. This means that the max connector argument for drm_fb_helper_init() and drm_fb_helper_fbdev_setup() isn't used anymore, a todo entry for this is added. In pan_display_atomic() restore_fbdev_mode_force() is used instead of restore_fbdev_mode_atomic() because that one will later become internal to drm_client_modeset. Locking order: 1. drm_fb_helper->lock 2. drm_master_internal_acquire 3. drm_client_dev->modeset_mutex v6: Improve commit message (Sam Ravnborg) v3: - Use full drm_client_init/release for the modesets (Daniel Vetter) - drm_client_for_each_modeset: use lockdep_assert_held (Daniel Vetter) - Hook up to Documentation/gpu/drm-client.rst (Daniel Vetter) v2: - Add modesets array to drm_client (Daniel Vetter) - Use a new file for the modeset code (Daniel Vetter) - File has to be MIT licensed (Emmanuel Vadot) - Add copyrights from drm_fb_helper.c Signed-off-by: Noralf Trønnes <noralf@tronnes.org> Reviewed-by: Sam Ravnborg <sam@ravnborg.org> Link: https://patchwork.freedesktop.org/patch/msgid/20190531140117.37751-3-noralf@tronnes.org |
