2018-12-10drm/dp/mst: Configure no_stop_bit correctly for remote i2c xfersVille Syrjälä
We aren't supposed to force a stop+start between every i2c msg when performing multi message transfers. This should eg. cause the DDC segment address to be reset back to 0 between writing the segment address and reading the actual EDID extension block. To quote the E-DDC spec: "... this standard requires that the segment pointer be reset to 00h when a NO ACK or a STOP condition is received." Since we're going to touch this might as well consult the I2C_M_STOP flag to determine whether we want to force the stop or not.

On the Amlogic GXL & GXM SoCs, a bug occurs on the primary plane when alpha is used where the alpha is not aligned with the pixel content. The workaround Amlogic implemented is to reset the OSD1 plane hardware block each time the plane is (re)enabled, solving the issue. In the reset, we still need to save the content of 2 registers which depends on the status of the plane, in addition to reload the scaler conversion matrix at the same time.

2018-11-29drm: Move atomic_state_put after locks are droppedSean Paul
drm_atomic_state_put doesn't require any locking, and this makes things easier for switching to modeset_lock_all helpers in a future patch Changes in v2: - Moved state->acquire_ctx clear to a separate patch (Daniel) Reviewed-by: Daniel Vetter <daniel@ffwll.ch> Signed-off-by: Sean Paul <seanpaul@chromium.org> Link: https://patchwork.freedesktop.org/patch/msgid/20181129150423.239081-3-sean@poorly.run
2018-11-29drm: Move drm_mode_setcrtc() local re-init to failure pathSean Paul
Instead of always re-initializing the variables we need to clean up on out, move the re-initialization into the branch that goes back to retry label. This is a lateral move right now, but will allow us to pull out the modeset locking into common code. I kept this change separate to make things easier to review.

2018-11-29drm: Clear state->acquire_ctx before leaving ↵Sean Paul
drm_atomic_helper_commit_duplicated_state() drm_atomic_helper_commit_duplicated_state() sets state->acquire_ctx to the context given in the argument and leaves it in state after it quits. The lifetime of state and context are not guaranteed to be the same, so we shouldn't leave that pointer hanging around. This patch resets the context to NULL to avoid any oopses.

2018-11-29drm/rcar-du: Use drm_fbdev_generic_setup()Noralf Trønnes
The CMA helper is already using the drm_fb_helper_generic_probe part of the generic fbdev emulation. This patch makes full use of the generic fbdev emulation by using its drm_client callbacks. This means that drm_mode_config_funcs->output_poll_changed and drm_driver->lastclose are now handled by the emulation code. Additionally fbdev unregister happens automatically on drm_dev_unregister(). The drm_fbdev_generic_setup() call is put after drm_dev_register() in the driver. This is done to highlight the fact that fbdev emulation is an internal client that makes use of the driver, it is not part of the driver as such. If fbdev setup fails, an error is printed, but the driver succeeds probing. drm_fbdev_generic_setup() handles mode_config.num_connector being zero. In that case it retries fbdev setup on the next .output_poll_changed.

2018-11-29drm/virtio: fence: pass plain pointerGerd Hoffmann
Since commit "9fdd90c0f4 drm/virtio: add virtio_gpu_alloc_fence()" fences are not allocated any more by virtio_gpu_fence_emit(). So there is no need to pass down a reference to the fence pointer, a plain pointer is enough now. Convert virtio_gpu_fence_emit() and callers.
