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.

When everyone implements it exactly the same way, among all 4 implementations, there's not really a need to overwrite this at all. Aside: drm_kms_helper_hotplug_event is pretty much core functionality at this point. Probably should move it there. Reviewed-by:

According to Dave, once you've started an L2T flush, all L2T accesses will be blocked until the flush completes. This fixes a consistent 3-4ms stall between the ioctl and running the job, and 3DMMES Taiji goes from 27fps to 110fps. v2: Leave a note about why we don't need to wait for completion. Signed-off-by:

For a lot of use cases we need 64bit sequence numbers. Currently drivers overload the dma_fence structure to store the additional bits. Stop doing that and make the sequence number in the dma_fence always 64bit. For compatibility with hardware which can do only 32bit sequences the comparisons in __dma_fence_is_later only takes the lower 32bits as significant when the upper 32bits are all zero. v2: change the logic in __dma_fence_is_later Signed-off-by:

This reverts commit 9a09a423. The whole interface isn't thought through. Since this function can't fail we actually can't allocate an object to store the sync point. Sorry, I should have taken the lead on this from the very beginning and reviewed it more thoughtfully. Going to propose a new interface as a follow up change. Signed-off-by:

The core scheduler tells us when the job is pushed to the scheduler's queue, and I had the job_run functions saying when they actually queue the job to the hardware. By adding tracepoints for the very top of the ioctls and the IRQs signaling job completion, "perf record -a -e v3d:.\* -e gpu_scheduler:.\* <job>; perf script" gets you a pretty decent timeline.

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. Signed-off-by:

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.

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.

Boris Brezillon authored
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:

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.
