[PATCH] dmabuf: ensure unique directory name for dmabuf stats

by Charan Teja Kalla

The dmabuf file uses get_next_ino()(through dma_buf_getfile() -> alloc_anon_inode()) to get an inode number and uses the same as a directory name under /sys/kernel/dmabuf/buffers/<ino>. This directory is used to collect the dmabuf stats and it is created through dma_buf_stats_setup(). At current, failure to create this directory entry can make the dma_buf_export() to fail. Now, as the get_next_ino() can definitely give a repetitive inode no causing the directory entry creation to fail with -EEXIST. This is a problem on the systems where dmabuf stats functionality is enabled on the production builds can make the dma_buf_export(), though the dmabuf memory is allocated successfully, to fail just because it couldn't create stats entry. This issue we are able to see on the snapdragon system within 13 days where there already exists a directory with inode no "122602" so dma_buf_stats_setup() failed with -EEXIST as it is trying to create the same directory entry. To make the directory entry as unique, append the inode creation time to the inode. With this change the stats directory entries will be in the format of: /sys/kernel/dmabuf/buffers/<inode no>-<inode creation time in secs>.

[PATCH] dma-buf: call dma_buf_stats_setup after dmabuf is in valid list

by Charan Teja Kalla

From: Charan Teja Reddy <quic_charante(a)quicinc.com> When dma_buf_stats_setup() fails, it closes the dmabuf file which results into the calling of dma_buf_file_release() where it does list_del(&dmabuf->list_node) with out first adding it to the proper list. This is resulting into panic in the below path: __list_del_entry_valid+0x38/0xac dma_buf_file_release+0x74/0x158 __fput+0xf4/0x428 ____fput+0x14/0x24 task_work_run+0x178/0x24c do_notify_resume+0x194/0x264 work_pending+0xc/0x5f0 Fix it by moving the dma_buf_stats_setup() after dmabuf is added to the list.

[PATCH] drm/nouveau: reorder nouveau_drm_device_fini

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

by Cai Huoqing

The NVIDIA Deep Learning Accelerator (NVDLA) is an open source IP which is integrated into NVIDIA Jetson AGX Xavier, so add driver support for this accelerator." v1->v2: *Rename nvdla_drm.[ch] to nvdla_drv.[ch] and rename nvdla_ioctl.h to nvdla_drm.h, move it to uapi. comments link: https://lore.kernel.org/lkml/20bac605-97e6-e5cd-c4e4-83a8121645d8@amd.com/ *Remove the onexistent filename in Makefile comments link: https://lore.kernel.org/lkml/202204201512.pp20MXT5-lkp@intel.com/ *Sort file names alphabetically in Makefile. *Rearrange the error messages, and use drm_err/_dbg() instead of pr_err/_dbg(). *Replace "dla_" prefix with "nvdla_" *Check the iosys_map by iosys_map_is_null(), and check "ret" directly. *Using iosys_map_memcpy_to/_from() for iosys_map instead of memcpy() *Fix parameter error "dma_buf_vunmap(buf, ptr)", use "&map" instead of "ptr" *Use iosys_map instead of kvaddr and use "iosys_map_set_vaddr()" to initialize iosys_map *Using "vma->vm_pgoff -= drm_vma_node_start(&obj->vma_node)" to update vm_pgoff is cleaner *Remove the unused nvdla_drm_gem_mmap, register drm_gem_mmap to file_operations directly. *Use DEFINE_DRM_GEM_FOPS() to define nvdla_drm_fops. *Remove the unused nvdla_drm_gem_mmap_buf, register drm_gem_prime_mmap to drm_driver directly. comments link: https://lore.kernel.org/lkml/7fa19996-5830-af3d-ab24-08c76e1d5604@suse.de/ *Fix typo and some code style *Remove unused function nvdla_get_time_us() comments link: https://lore.kernel.org/lkml/0fa9ab41-c18e-a569-e6fe-a0e9d965905e@stargateu… Cai Huoqing (4): MAINTAINERS: Add the driver info of the NVDLA drm/nvdla: Add driver support for NVDLA drm/nvdla: Add register head file of NVDLA drm/nvdla/uapi: Add UAPI of NVDLA driver MAINTAINERS | 7 + drivers/gpu/drm/Kconfig | 2 + drivers/gpu/drm/Makefile | 1 + drivers/gpu/drm/nvdla/Kconfig | 8 + drivers/gpu/drm/nvdla/Makefile | 17 + drivers/gpu/drm/nvdla/nvdla_bdma.c | 198 + drivers/gpu/drm/nvdla/nvdla_cache.c | 202 + drivers/gpu/drm/nvdla/nvdla_cdp.c | 299 ++ drivers/gpu/drm/nvdla/nvdla_common.c | 293 ++ drivers/gpu/drm/nvdla/nvdla_common.h | 835 +++ drivers/gpu/drm/nvdla/nvdla_conv.c | 684 +++ drivers/gpu/drm/nvdla/nvdla_drv.c | 694 +++ drivers/gpu/drm/nvdla/nvdla_drv.h | 129 + drivers/gpu/drm/nvdla/nvdla_engine.c | 233 + drivers/gpu/drm/nvdla/nvdla_engine.h | 272 + drivers/gpu/drm/nvdla/nvdla_gem.c | 358 ++ drivers/gpu/drm/nvdla/nvdla_pdp.c | 448 ++ drivers/gpu/drm/nvdla/nvdla_reg.h | 6411 +++++++++++++++++++++++ drivers/gpu/drm/nvdla/nvdla_rubik.c | 214 + drivers/gpu/drm/nvdla/nvdla_sched.h | 37 + drivers/gpu/drm/nvdla/nvdla_scheduler.c | 1012 ++++ drivers/gpu/drm/nvdla/nvdla_sdp.c | 723 +++ include/uapi/drm/nvdla_drm.h | 99 + 23 files changed, 13176 insertions(+) create mode 100644 drivers/gpu/drm/nvdla/Kconfig create mode 100644 drivers/gpu/drm/nvdla/Makefile create mode 100644 drivers/gpu/drm/nvdla/nvdla_bdma.c create mode 100644 drivers/gpu/drm/nvdla/nvdla_cache.c create mode 100644 drivers/gpu/drm/nvdla/nvdla_cdp.c create mode 100644 drivers/gpu/drm/nvdla/nvdla_common.c create mode 100644 drivers/gpu/drm/nvdla/nvdla_common.h create mode 100644 drivers/gpu/drm/nvdla/nvdla_conv.c create mode 100644 drivers/gpu/drm/nvdla/nvdla_drv.c create mode 100644 drivers/gpu/drm/nvdla/nvdla_drv.h create mode 100644 drivers/gpu/drm/nvdla/nvdla_engine.c create mode 100644 drivers/gpu/drm/nvdla/nvdla_engine.h create mode 100644 drivers/gpu/drm/nvdla/nvdla_gem.c create mode 100644 drivers/gpu/drm/nvdla/nvdla_pdp.c create mode 100644 drivers/gpu/drm/nvdla/nvdla_reg.h create mode 100644 drivers/gpu/drm/nvdla/nvdla_rubik.c create mode 100644 drivers/gpu/drm/nvdla/nvdla_sched.h create mode 100644 drivers/gpu/drm/nvdla/nvdla_scheduler.c create mode 100644 drivers/gpu/drm/nvdla/nvdla_sdp.c create mode 100644 include/uapi/drm/nvdla_drm.h -- 2.25.1
