drm/fb-helper: Remove drm_fb_helper_connector

2019-06-11T12:46:44+00:00

All drivers add all their connectors so there's no need to keep around an array of available connectors. Instead we just put the useable (not writeback) connectors in a temporary array using drm_client_for_each_connector_iter() everytime we probe the outputs. Other places where it's necessary to look at the connectors, we just iterate over them using the same iterator function. Rename functions which signature is changed since they will be moved to drm_client in a later patch. v6: Improve commit message (Sam Ravnborg) Signed-off-by: Noralf Trønnes Reviewed-by: Sam Ravnborg Link: https://patchwork.freedesktop.org/patch/msgid/20190608152657.36613-2-noralf@tronnes.org

drm/fb-helper: Remove drm_fb_helper_crtc

2019-06-04T10:13:47+00:00

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 Reviewed-by: Sam Ravnborg Link: https://patchwork.freedesktop.org/patch/msgid/20190531140117.37751-3-noralf@tronnes.org

drm/fb-helper: Avoid race with DRM userspace

2019-05-14T14:11:28+00:00

drm_fb_helper_is_bound() is used to check if DRM userspace is in control. This is done by looking at the fb on the primary plane. By the time fb-helper gets around to committing, it's possible that the facts have changed. Avoid this race by holding the drm_device->master_mutex lock while committing. When DRM userspace does its first open, it will now wait until fb-helper is done. The helper will stay away if there's a master. Two igt tests fail with the new 'bail out if master' rule. Work around this by relaxing this rule for drm_fb_helper_restore_fbdev_mode_unlocked() until the tests have been fixed. Add todo entry for this. Locking rule: Always take the fb-helper lock first. v5: drm_fb_helper_restore_fbdev_mode_unlocked(): Use restore_fbdev_mode_force() v2: - Remove drm_fb_helper_is_bound() (Daniel Vetter) - No need to check fb_helper->dev->master in drm_fb_helper_single_fb_probe(), restore_fbdev_mode() has the check.

drm: Add reservation_object to drm_gem_object

2019-02-19T10:08:40+00:00

Many users of drm_gem_object embed a struct reservation_object into their subclassed struct, so let's add one to struct drm_gem_object. This will allow removing the reservation object from the subclasses and removing the ->gem_prime_res_obj callback. With the addition, add a drm_gem_reservation_object_wait() helper function for drivers to use in wait ioctls.
