drm/atomic: Don't pollute crtc_state->mode_blob with error pointers

2022-02-16T10:32:07Z

Make sure we don't assign an error pointer to crtc_state->mode_blob as that will break all kinds of places that assume either NULL or a valid pointer (eg. drm_property_blob_put()).

drm: get rid of DRM_DEBUG_* log calls in drm core, files drm_a*.c

2021-11-26T15:45:22Z

DRM_DEBUG_* and DRM_* log calls are deprecated. Change them to drm_dbg_* / drm_{err,info,...} calls in drm core files. To avoid making a very big patch, this change is split in smaller patches.

drm/connector: Add support for privacy-screen properties (v4)

2021-10-14T11:12:20Z

Add support for generic electronic privacy screen properties, that can be added by systems that have an integrated EPS. Changes in v2 (Hans de Goede) - Create 2 properties, "privacy-screen sw-state" and "privacy-screen hw-state", to deal with devices where the OS might be locked out of making state changes - Write kerneldoc explaining how the 2 properties work together, what happens when changes to the state are made outside of the DRM code's control, etc. Changes in v3 (Hans de Goede) - Some small tweaks to the kerneldoc describing the 2 properties Changes in v4 (Hans de Goede) - Change the "Enabled, locked" and "Disabled, locked" hw-state enum value names to "Enabled-locked" and "Disabled-locked". The xrandr command shows all possible enum values separated by commas in its output, so having a comma in an enum name is not a good idea. - Do not add a privacy_screen_hw_state member to drm_connector_state since this property is immutable its value must be directly stored in the obj->properties->values array Signed-off-by: Rajat Jain Acked-by: Pekka Paalanen Reviewed-by: Mario Limonciello Reviewed-by: Emil Velikov Reviewed-by: Lyude Paul Co-developed-by: Hans de Goede Signed-off-by: Hans de Goede Link: https://patchwork.freedesktop.org/patch/msgid/20211005202322.700909-2-hdegoede@redhat.com

drm: allow drm_atomic_print_state() to accept any drm_printer

2021-06-23T14:32:13Z

Currently drm_atomic_print_state() internally allocates and uses a drm_info printer. Allow it to accept any drm_printer type so that the API can be leveraged even for taking drm snapshot. Rename the drm_atomic_print_state() to drm_atomic_print_new_state() so that it reflects its functionality better. changes in v5: - none Reported-by: kernel test robot Signed-off-by: Abhinav Kumar Reviewed-by: Daniel Vetter Reviewed-by: Dmitry Baryshkov Link: https://lore.kernel.org/r/1618606645-19695-2-git-send-email-abhinavk@codeaurora.org Signed-off-by: Rob Clark
