Use managed memory allocation for this. That allows us to not keep track of all the files any more. v2: keep drm_debugfs_cleanup(), but rename to drm_debugfs_unregister(), we still need to cleanup the symlink Signed-off-by:Christian König <christian.koenig@amd.com> Link: https://patchwork.freedesktop.org/patch/msgid/20230829110115.3442-6-christian.koenig@amd.comReviewed-by:

The mutex was completely pointless in the first place since any parallel adding of files to this list would result in random behavior since the list is filled and consumed multiple times. Completely drop that approach and just create the files directly but return -ENODEV while opening the file when the minors are not registered yet. v2: rebase on debugfs directory rework, limit access before minors are registered.

Instead of the per minor directories only create a single debugfs directory for the whole device directly when the device is initialized. For DRM devices each minor gets a symlink to the per device directory for now until we can be sure that this isn't useful any more in any way. Accel devices create only the per device directory and also drops the mid layer callback to create driver specific files. v2: cleanup accel component as well v3: fix typo when debugfs is disabled v4: call drm_debugfs_dev_fini() during release as well, some kerneldoc typos fixed v5: rebased and one more kerneldoc fix Signed-off-by:

Currently, NO_PREFETCH is passed implicitly through drm_nouveau_gem_pushbuf_push::length and drm_nouveau_exec_push::va_len. Since this is a direct representation of how the HW is programmed it isn't really future proof for a uAPI. Hence, fix this up for the new uAPI and split up the va_len field of struct drm_nouveau_exec_push, such that we keep 32bit for va_len and 32bit for flags. For drm_nouveau_gem_pushbuf_push::length at least provide NOUVEAU_GEM_PUSHBUF_NO_PREFETCH to indicate the bit shift. While at it, fix up nv50_dma_push() as well, such that the caller doesn't need to encode the NO_PREFETCH flag into the length parameter. Signed-off-by:

If a sched job depends on a dma-fence from a job from the same GPU scheduler instance, but a different scheduler entity, the GPU scheduler does only wait for the particular job to be scheduled, rather than for the job to fully complete. This is due to the GPU scheduler assuming that there is a scheduler instance per ring. However, the current implementation, in order to avoid arbitrary amounts of kthreads, has a single scheduler instance while scheduler entities represent rings. As a workaround, set the DRM_SCHED_FENCE_DONT_PIPELINE for all out-fences in order to force the scheduler to wait for full job completion for dependent jobs from different entities and same scheduler instance. There is some work in progress [1] to address the issues of firmware schedulers; once it is in-tree the scheduler topology in Nouveau should be re-worked accordingly.

The JDI LPM102A188A is a 2560x1800 IPS panel found in the Google Pixel C. This driver is based on the downstream GPLv2 driver released by Google written by Sean Paul [1], which was then adapted to the newer kernel APIs.
