v3d_bo_get_pages() checks this to decide to map the imported buffer instead of the backing shmem file. The caller was about to set this value anyway, and there's no error path in between. Ideally we wouldn't even allocate the shmem file for our imports, but that's a more invasive fix. Signed-off-by:

They were unused, as Dave Emett noticed in TFU review. Signed-off-by:
-
Eric Anholt authored
The TFU can copy from raster, UIF, and SAND input images to UIF output images, with optional mipmap generation. This will certainly be useful for media EGL image input, but is also useful immediately for mipmap generation without bogging the V3D core down. For now we only run the queue 1 job deep, and don't have any hang recovery (though I don't think we should need it, with TFU). Queuing multiple jobs in the HW will require synchronizing the YUV coefficient regs updates since they don't get FIFOed with the job. v2: Change the ioctl to IOW instead of IOWR, always set COEF0, explain why TFU is AUTH, clarify the syncing docs, drop the unused TFU interrupt regs (you're expected to use the hub's), don't take &bo->base for NULL bos. v3: Fix a little whitespace alignment (noticed by checkpatch), rebase on drm_sched_job_cleanup() changes.

Now that async update has been reworked to allow scaled planes to be updated asynchronously when the scaling params do not change, we can remove the NO_SCALING constraint on cursor planes. Signed-off-by:
-
Boris Brezillon authored
vc4_plane_atomic_async_check() was only based on the state->{crtc,src}_{w,h} which was fine since scaling was not allowed on the cursor plane. We are about to change that to properly support underscan, and, in order to make the async check more reliable, we call vc4_plane_mode_set() from there and check that only the pos0, pos2 and ptr0 entries in the dlist have changed. In vc4_plane_atomic_async_update(), we no longer call vc4_plane_atomic_check() since vc4_plane_mode_set() has already been called in vc4_plane_atomic_async_check(), and we don't need to allocate a new LBM region (we reuse the one from the current state). Note that we now have to manually update each field of the current plane state since it's no longer updated in place (not sure we have to sync all of them, but it's harmless if we do). We also drop the vc4_plane_async_set_fb() call (ptr0 dlist entry has been properly updated in vc4_plane_mode_set()) Signed-off-by: -
Boris Brezillon authored
We are about to use vc4_plane_mode_set() in the async check path, but async check can decide that async update is not possible and force the driver to fallback to a sync update. All the checks that have been done on the plane state during async check stay valid, and checking it again is not necessary. Add a ->checked field to vc4_plane_state, and use it to track the status of the state (checked or not). Signed-off-by:

Boris Brezillon authored
We are about to use vc4_plane_mode_set() in the async check path, and async updates require that LBM size stay the same since they reuse the LBM from the previous state. So we definitely don't want to allocate a new LBM region that we know for sure will be free right away. Move the LBM allocation out of vc4_plane_mode_set() and call the new function (vc4_plane_update_lbm()) from vc4_plane_atomic_check(). Signed-off-by:

LBM is not needed when vertical scaling is disabled. Return 0 in this case to avoid allocating LBM memory that will anyway be unused. While at it, drop the test on ->is_unity which is now redundant. Signed-off-by:

We should also get the drivers using the helpers. Seems like a good intermediate TODO item. Changes in v2: - Add line about replacing drm_modest_lock_all() (Daniel) Acked-by:
-
Sean Paul authored
This patch adds a couple of helpers to remove the boilerplate involved in grabbing all of the modeset locks. I've also converted the obvious cases in drm core to use the helpers. The only remaining instance of drm_modeset_lock_all_ctx() is in drm_framebuffer. It's complicated by the state clear that occurs on deadlock. ATM, there's no way to inject code in the deadlock path with the helpers, so it's unfit for conversion. Changes in v2: - Relocate ret argument to the end of the list (Daniel) - Incorporate Daniel's doc suggestions (Daniel) Suggested-by:

Sean Paul authored
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. Changes in v2: - None Reviewed-by:

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.

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. Cc: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by:

This change is an attempt to handle the alternate clock for the CEA mode. 60Hz vs. 59.94Hz, 30Hz vs 29.97Hz or 24Hz vs 23.97Hz on the Amlogic Meson SoC DRM Driver pixel clock generation.

Our hardware requires the pitch to be an even number when using YUV formats with the frontend. Implement a driver-specific callback for GEM dumb allocation that sets the pitch accordingly.

The frontend comes with two "channels", that can be configured independently. When used in YUV mode, the first channel (CH0) represents the luminance component while the second channel (CH1) represents the chrominance. In RGB mode, both have to be configured the same way. Use variables (with the YUV terminology) for each channel's dimensions, calculating the chroma dimensions from the luma dimensions and the sub-sampling factors from the format description. Since the configured size only has pixel precision, the fractional fixed-point part of the source size is dropped for both components to ensure that the scaling factors are accurate. Signed-off-by:
