drm/vc4: fix fb references in async update

2019-06-15T09:54:11+00:00

commit c16b85559dcfb5a348cc085a7b4c75ed49b05e2c upstream. Async update callbacks are expected to set the old_fb in the new_state so prepare/cleanup framebuffers are balanced. Calling drm_atomic_set_fb_for_plane() (which gets a reference of the new fb and put the old fb) is not required, as it's taken care by drm_mode_cursor_universal() when calling drm_atomic_helper_update_plane().

drm/vc4: Fix memory leak during gpu reset.

commit d08106796a78a4273e39e1bbdf538dc4334b2635 upstream. __drm_atomic_helper_crtc_destroy_state does not free memory, it only cleans it up. Fix this by calling the functions own destroy function.

drm/vc4: ->x_scaling[1] should never be set to VC4_SCALING_NONE

2019-02-12T18:46:59+00:00

[ Upstream commit 0560054da5673b25d56bea6c57c8d069673af73b ] For the YUV conversion to work properly, ->x_scaling[1] should never be set to VC4_SCALING_NONE, but vc4_get_scaling_mode() might return VC4_SCALING_NONE if the horizontal scaling ratio exactly matches the horizontal subsampling factor. Add a test to turn VC4_SCALING_NONE into VC4_SCALING_PPF when that happens. The old ->x_scaling[0] adjustment is dropped as I couldn't find any mention to this constraint in the spec and it's proven to be unnecessary (I tested various multi-planar YUV formats with scaling disabled, and all of them worked fine without this adjustment).

drm/vc4: Set ->is_yuv to false when num_planes == 1

2019-01-13T08:51:10+00:00

commit 2b02a05bdc3a62d36e0d0b015351897109e25991 upstream. When vc4_plane_state is duplicated ->is_yuv is left assigned to its previous value, and we never set it back to false when switching to a non-YUV format. Fix that by setting ->is_yuv to false in the 'num_planes == 1' branch of the vc4_plane_setup_clipping_and_scaling() function. Fixes: fc04023fafecf ("drm/vc4: Add support for YUV planes.")

drm/vc4: Set ->legacy_cursor_update to false when doing non-async updates

2018-12-01T08:37:28+00:00

commit fcc86cb45d38ca2f24bcea9c29c7f4742041caed upstream. drm_atomic_helper_setup_commit() auto-completes commit->flip_done when state->legacy_cursor_update is true, but we know for sure that we want a sync update when we call drm_atomic_helper_setup_commit() from vc4_atomic_commit(). Explicitly set state->legacy_cursor_update to false to prevent this auto-completion.

drm/vc4: Fix the "no scaling" case on multi-planar YUV formats

2018-09-10T20:01:22+00:00

When there's no scaling requested ->is_unity should be true no matter the format. Also, when no scaling is requested and we have a multi-planar YUV format, we should leave ->y_scaling[0] to VC4_SCALING_NONE and only set ->x_scaling[0] to VC4_SCALING_PPF. Doing this fixes an hardly visible artifact (seen when using modetest and a rather big overlay plane in YUV420). Fixes: fc04023fafec ("drm/vc4: Add support for YUV planes.")

drm/vc4: Reset ->{x, y}_scaling[1] when dealing with uniplanar formats

2018-07-25T19:15:24+00:00

This is needed to ensure ->is_unity is correct when the plane was previously configured to output a multi-planar format with scaling enabled, and is then being reconfigured to output a uniplanar format.
