[PATCH] drm/nouveau: reorder nouveau_drm_device_fini

by Mark Menzynski

Resources needed for output poll workers are destroyed in nouveau_fbcon_fini() before output poll workers are cleared in nouveau_display_fini(). This means there is a time between fbcon_fini and display_fini, where if output poll happens, it crashes.

[PATCH v6 0/6] Proposal for a GPU cgroup controller

by T.J. Mercier

This patch series revisits the proposal for a GPU cgroup controller to track and limit memory allocations by various device/allocator subsystems. The patch series also contains a simple prototype to illustrate how Android intends to implement DMA-BUF allocator attribution using the GPU cgroup controller. The prototype does not include resource limit enforcements. Changelog: v6: Move documentation into cgroup-v2.rst per Tejun Heo. Rename BINDER_FD{A}_FLAG_SENDER_NO_NEED -> BINDER_FD{A}_FLAG_XFER_CHARGE per Carlos Llamas. Return error on transfer failure per Carlos Llamas. v5: Rebase on top of v5.18-rc3 Drop the global GPU cgroup "total" (sum of all device totals) portion of the design since there is no currently known use for this per Tejun Heo. Fix commit message which still contained the old name for dma_buf_transfer_charge per Michal Koutný. Remove all GPU cgroup code except what's necessary to support charge transfer from dma_buf. Previously charging was done in export, but for non-Android graphics use-cases this is not ideal since there may be a delay between allocation and export, during which time there is no accounting. Merge dmabuf: Use the GPU cgroup charge/uncharge APIs patch into dmabuf: heaps: export system_heap buffers with GPU cgroup charging as a result of above. Put the charge and uncharge code in the same file (system_heap_allocate, system_heap_dma_buf_release) instead of splitting them between the heap and the dma_buf_release. This avoids asymmetric management of the gpucg charges. Modify the dma_buf_transfer_charge API to accept a task_struct instead of a gpucg. This avoids requiring the caller to manage the refcount of the gpucg upon failure and confusing ownership transfer logic. Support all strings for gpucg_register_bucket instead of just string literals. Enforce globally unique gpucg_bucket names. Constrain gpucg_bucket name lengths to 64 bytes. Append "-heap" to gpucg_bucket names from dmabuf-heaps. Drop patch 7 from the series, which changed the types of binder_transaction_data's sender_pid and sender_euid fields. This was done in another commit here: https://lore.kernel.org/all/20220210021129.3386083-4-masahiroy@kernel.org/ Rename: gpucg_try_charge -> gpucg_charge find_cg_rpool_locked -> cg_rpool_find_locked init_cg_rpool -> cg_rpool_init get_cg_rpool_locked -> cg_rpool_get_locked "gpu cgroup controller" -> "GPU controller" gpucg_device -> gpucg_bucket usage -> size Tests: Support both binder_fd_array_object and binder_fd_object. This is necessary because new versions of Android will use binder_fd_object instead of binder_fd_array_object, and we need to support both. Tests for both binder_fd_array_object and binder_fd_object. For binder_utils return error codes instead of struct binder{fs}_ctx. Use ifdef __ANDROID__ to choose platform-dependent temp path instead of a runtime fallback. Ensure binderfs_mntpt ends with a trailing '/' character instead of prepending it where used. v4: Skip test if not run as root per Shuah Khan Add better test logging for abnormal child termination per Shuah Khan Adjust ordering of charge/uncharge during transfer to avoid potentially hitting cgroup limit per Michal Koutný Adjust gpucg_try_charge critical section for charge transfer functionality Fix uninitialized return code error for dmabuf_try_charge error case v3: Remove Upstreaming Plan from gpu-cgroup.rst per John Stultz Use more common dual author commit message format per John Stultz Remove android from binder changes title per Todd Kjos Add a kselftest for this new behavior per Greg Kroah-Hartman Include details on behavior for all combinations of kernel/userspace versions in changelog (thanks Suren Baghdasaryan) per Greg Kroah-Hartman. Fix pid and uid types in binder UAPI header v2: See the previous revision of this change submitted by Hridya Valsaraju at: https://lore.kernel.org/all/20220115010622.3185921-1-hridya@google.com/ Move dma-buf cgroup charge transfer from a dma_buf_op defined by every heap to a single dma-buf function for all heaps per Daniel Vetter and Christian König. Pointers to struct gpucg and struct gpucg_device tracking the current associations were added to the dma_buf struct to achieve this. Fix incorrect Kconfig help section indentation per Randy Dunlap. History of the GPU cgroup controller ==================================== The GPU/DRM cgroup controller came into being when a consensus[1] was reached that the resources it tracked were unsuitable to be integrated into memcg. Originally, the proposed controller was specific to the DRM subsystem and was intended to track GEM buffers and GPU-specific resources[2]. In order to help establish a unified memory accounting model for all GPU and all related subsystems, Daniel Vetter put forth a suggestion to move it out of the DRM subsystem so that it can be used by other DMA-BUF exporters as well[3]. This RFC proposes an interface that does the same.

[PATCH v2 0/4] drm/nvdla: Add driver support for NVDLA

[PATCH 1/3] dma-buf/sync_file: cleanup fence merging a bit

by Christian König

krealloc_array() ignores attempts to reduce the array size, so the attempt to save memory is completely pointless here. Also move testing for the no fence case into sync_file_set_fence(), this way we don't even touch the fence array when we don't have any fences.

[PATCH 1/4] drm/etnaviv: Use scheduler dependency handling

by Daniel Vetter

We need to pull the drm_sched_job_init much earlier, but that's very minor surgery. v2: Actually fix up cleanup paths by calling drm_sched_job_init, which I wanted to to in the previous round (and did, for all other drivers). Spotted by Lucas. v3: Rebase over renamed functions to add dependencies. v4: Rebase over patches from Christian. v5: More rebasing over work from Christian.

[PATCH] dma-buf: add the name field to the table header

by Yuanzheng Song

'cat /sys/kernel/debug/dma_buf/bufinfo' will print the Dma-buf Objects' information when the CONFIG_DEBUG_FS=y. However, the printed table header information does not contain the name field. So we need to add the name field to the table header and use the '<none>' to replace the empty buf_obj->name.
