drm/simple_kms_helper: Add {enable|disable}_vblank callback support

2018-02-22T16:58:59Z

If simple_kms_helper based driver needs to work with vblanks, then it has to provide drm_driver.{enable|disable}_vblank callbacks, because drm_simple_kms_helper.drm_crtc_funcs does not provide any. At the same time drm_driver.{enable|disable}_vblank callbacks are marked as deprecated and shouldn't be used by new drivers. Fix this by extending drm_simple_kms_helper.drm_crtc_funcs to provide the missing callbacks.

drm/simple_kms_helper: Fix NULL pointer dereference with no active CRTC

2018-02-22T16:11:46Z

It is possible that drm_simple_kms_plane_atomic_check called with no CRTC set, e.g. when user-space application sets CRTC_ID/FB_ID to 0 before doing any actual drawing. This leads to NULL pointer dereference because in this case new CRTC state is NULL and must be checked before accessing.

drm: simple_kms_helper: Add mode_valid() callback support

2018-02-20T07:42:17Z

The PL111 needs to filter valid modes based on memory bandwidth. I guess it is a pretty simple operation, so we can still claim the DRM KMS helper pipeline is simple after adding this (optional) vtable callback.

drm/simple_kms_helper: Use drm_mode_get_hv_timing() to populate plane clip rectangle

2018-01-23T15:41:40Z

Use drm_mode_get_hv_timing() to fill out the plane clip rectangle. Note that this replaces crtc_state->adjusted_mode usage with crtc_state->mode. The latter is the correct choice since that's the mode the user provided and it matches the plane crtc coordinates the user also provided. Once everyone agrees on this we can move the clip handling into drm_atomic_helper_check_plane_state().

drm: Check crtc_state->enable rather than crtc->enabled in drm_plane_helper_check_state()

2017-11-20T18:33:21Z

drm_plane_helper_check_state() is supposed to do things the atomic way, so it should not be inspecting crtc->enabled. Rather we should be looking at crtc_state->enable. We have a slight complication due to drm_plane_helper_check_update() reusing drm_plane_helper_check_state() for non-atomic drivers. Thus we'll have to pass the crtc_state in manally and construct a fake crtc_state in drm_plane_helper_check_update(). v2: Fix the WARNs about plane_state->crtc matching crtc_state->crtc Signed-off-by: Ville Syrjälä Link: https://patchwork.freedesktop.org/patch/msgid/20171101201558.6059-1-ville.syrjala@linux.intel.com Reviewed-by: Daniel Vetter

drm: Plumb modifiers through plane init

2017-08-01T16:50:06Z

This is the plumbing for supporting fb modifiers on planes. Modifiers have already been introduced to some extent, but this series will extend this to allow querying modifiers per plane. Based on this, the client to enable optimal modifications for framebuffers. This patch simply allows the DRM drivers to initialize their list of supported modifiers upon initializing the plane. v2: A minor addition from Daniel v3: * Updated commit message * s/INVALID/DRM_FORMAT_MOD_INVALID (Liviu) * Remove some excess newlines (Liviu) * Update comment for > 64 modifiers (Liviu) v4: Minor comment adjustments (Liviu) v5: Some new platforms added due to rebase v6: Add some missed plane inits (or maybe they're new - who knows at this point) (Daniel) Signed-off-by: Ben Widawsky Reviewed-by: Daniel Stone (v2) Reviewed-by: Liviu Dudau Signed-off-by: Daniel Stone

drm/simple-kms-helper: Fix the check for the mismatch between plane and CRTC enabled.

2017-07-13T07:44:51Z

You can enable the CRTC and without adding the plane to the state and it will succeed. This should be prevented in the crtc check instead of the plane check, because the plane check may never run for atomic enable, but the crtc check always will. This is based on a similar check in vmwgfx.

drm: Convert atomic drivers from CRTC .disable() to .atomic_disable()

2017-06-30T12:53:15Z

The CRTC .disable() helper operation is deprecated for atomic drivers, the new .atomic_disable() helper operation being preferred. Convert all atomic drivers to .atomic_disable() to avoid cargo-cult use of .disable() in new drivers.
