2022-06-08dma-buf: Add an API for importing sync files (v10)Jason Ekstrand1-0/+49
This patch is analogous to the previous sync file export patch in that it allows you to import a sync_file into a dma-buf. Unlike the previous patch, however, this does add genuinely new functionality to dma-buf. Without this, the only way to attach a sync_file to a dma-buf is to submit a batch to your driver of choice which waits on the sync_file and claims to write to the dma-buf. Even if said batch is a no-op, a submit is typically way more overhead than just attaching a fence. A submit may also imply extra synchronization with other work because it happens on a hardware queue. In the Vulkan world, this is useful for dealing with the out-fence from vkQueuePresent. Current Linux window-systems (X11, Wayland, etc.) all rely on dma-buf implicit sync. Since Vulkan is an explicit sync API, we get a set of fences (VkSemaphores) in vkQueuePresent and have to stash those as an exclusive (write) fence on the dma-buf. We handle it in Mesa today with the above mentioned dummy submit trick. This ioctl would allow us to set it directly without the dummy submit. This may also open up possibilities for GPU drivers to move away from implicit sync for their kernel driver uAPI and instead provide sync files and rely on dma-buf import/export for communicating with other implicit sync clients. We make the explicit choice here to only allow setting RW fences which translates to an exclusive fence on the dma_resv. There's no use for read-only fences for communicating with other implicit sync userspace and any such attempts are likely to be racy at best. When we got to insert the RW fence, the actual fence we set as the new exclusive fence is a combination of the sync_file provided by the user and all the other fences on the dma_resv. This ensures that the newly added exclusive fence will never signal before the old one would have and ensures that we don't break any dma_resv contracts. We require userspace to specify RW in the flags for symmetry with the export ioctl and in case we ever want to support read fences in the future. There is one downside here that's worth documenting: If two clients writing to the same dma-buf using this API race with each other, their actions on the dma-buf may happen in parallel or in an undefined order. Both with and without this API, the pattern is the same: Collect all the fences on dma-buf, submit work which depends on said fences, and then set a new exclusive (write) fence on the dma-buf which depends on said work. The difference is that, when it's all handled by the GPU driver's submit ioctl, the three operations happen atomically under the dma_resv lock. If two userspace submits race, one will happen before the other. You aren't guaranteed which but you are guaranteed that they're strictly ordered. If userspace manages the fences itself, then these three operations happen separately and the two render operations may happen genuinely in parallel or get interleaved. However, this is a case of userspace racing with itself. As long as we ensure userspace can't back the kernel into a corner, it should be fine. v2 (Jason Ekstrand): - Use a wrapper dma_fence_array of all fences including the new one when importing an exclusive fence. v3 (Jason Ekstrand): - Lock around setting shared fences as well as exclusive - Mark SIGNAL_SYNC_FILE as a read-write ioctl. - Initialize ret to 0 in dma_buf_wait_sync_file v4 (Jason Ekstrand): - Use the new dma_resv_get_singleton helper v5 (Jason Ekstrand): - Rename the IOCTLs to import/export rather than wait/signal - Drop the WRITE flag and always get/set the exclusive fence v6 (Jason Ekstrand): - Split import and export into separate patches - New commit message v7 (Daniel Vetter): - Fix the uapi header to use the right struct in the ioctl - Use a separate dma_buf_import_sync_file struct - Add kerneldoc for dma_buf_import_sync_file v8 (Jason Ekstrand): - Rebase on Christian König's fence rework v9 (Daniel Vetter): - Fix -EINVAL checks for the flags parameter - Add documentation about read/write fences - Add documentation about the expected usage of import/export and specifically call out the possible userspace race. v10 (Simon Ser): - Fix a typo in the docs Signed-off-by: Jason Ekstrand <[email protected]> Signed-off-by: Jason Ekstrand <[email protected]> Signed-off-by: Jason Ekstrand <[email protected]> Reviewed-by: Christian König <[email protected]> Reviewed-by: Daniel Vetter <[email protected]> Cc: Sumit Semwal <[email protected]> Cc: Maarten Lankhorst <[email protected]> Signed-off-by: Simon Ser <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]
2022-06-08dma-buf: Add an API for exporting sync files (v14)Jason Ekstrand1-0/+35
Modern userspace APIs like Vulkan are built on an explicit synchronization model. This doesn't always play nicely with the implicit synchronization used in the kernel and assumed by X11 and Wayland. The client -> compositor half of the synchronization isn't too bad, at least on intel, because we can control whether or not i915 synchronizes on the buffer and whether or not it's considered written. The harder part is the compositor -> client synchronization when we get the buffer back from the compositor. We're required to be able to provide the client with a VkSemaphore and VkFence representing the point in time where the window system (compositor and/or display) finished using the buffer. With current APIs, it's very hard to do this in such a way that we don't get confused by the Vulkan driver's access of the buffer. In particular, once we tell the kernel that we're rendering to the buffer again, any CPU waits on the buffer or GPU dependencies will wait on some of the client rendering and not just the compositor. This new IOCTL solves this problem by allowing us to get a snapshot of the implicit synchronization state of a given dma-buf in the form of a sync file. It's effectively the same as a poll() or I915_GEM_WAIT only, instead of CPU waiting directly, it encapsulates the wait operation, at the current moment in time, in a sync_file so we can check/wait on it later. As long as the Vulkan driver does the sync_file export from the dma-buf before we re-introduce it for rendering, it will only contain fences from the compositor or display. This allows to accurately turn it into a VkFence or VkSemaphore without any over-synchronization. By making this an ioctl on the dma-buf itself, it allows this new functionality to be used in an entirely driver-agnostic way without having access to a DRM fd. This makes it ideal for use in driver-generic code in Mesa or in a client such as a compositor where the DRM fd may be hard to reach. v2 (Jason Ekstrand): - Use a wrapper dma_fence_array of all fences including the new one when importing an exclusive fence. v3 (Jason Ekstrand): - Lock around setting shared fences as well as exclusive - Mark SIGNAL_SYNC_FILE as a read-write ioctl. - Initialize ret to 0 in dma_buf_wait_sync_file v4 (Jason Ekstrand): - Use the new dma_resv_get_singleton helper v5 (Jason Ekstrand): - Rename the IOCTLs to import/export rather than wait/signal - Drop the WRITE flag and always get/set the exclusive fence v6 (Jason Ekstrand): - Drop the sync_file import as it was all-around sketchy and not nearly as useful as import. - Re-introduce READ/WRITE flag support for export - Rework the commit message v7 (Jason Ekstrand): - Require at least one sync flag - Fix a refcounting bug: dma_resv_get_excl() doesn't take a reference - Use _rcu helpers since we're accessing the dma_resv read-only v8 (Jason Ekstrand): - Return -ENOMEM if the sync_file_create fails - Predicate support on IS_ENABLED(CONFIG_SYNC_FILE) v9 (Jason Ekstrand): - Add documentation for the new ioctl v10 (Jason Ekstrand): - Go back to dma_buf_sync_file as the ioctl struct name v11 (Daniel Vetter): - Go back to dma_buf_export_sync_file as the ioctl struct name - Better kerneldoc describing what the read/write flags do v12 (Christian König): - Document why we chose to make it an ioctl on dma-buf v13 (Jason Ekstrand): - Rebase on Christian König's fence rework v14 (Daniel Vetter & Christian König): - Use dma_rev_usage_rw to get the properly inverted usage to pass to dma_resv_get_singleton() - Clean up the sync_file and fd if copy_to_user() fails Signed-off-by: Jason Ekstrand <[email protected]> Signed-off-by: Jason Ekstrand <[email protected]> Signed-off-by: Jason Ekstrand <[email protected]> Acked-by: Simon Ser <[email protected]> Reviewed-by: Christian König <[email protected]> Reviewed-by: Daniel Vetter <[email protected]> Cc: Sumit Semwal <[email protected]> Cc: Maarten Lankhorst <[email protected]> Signed-off-by: Simon Ser <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]

git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic Pull initial Loongarch architecture code from Arnd Bergmann: "This is the majority of the loongarch architecture code, including the final system call interface and all core functionality. It still misses three sets of peripheral but vital patches to add support for other subsystems, which have yet to pass review: - The drivers/firmware/efi stub for booting from a standard UEFI firmware implementation. Both the original custom boot interface and a draft implementation of the EFI stub did not make it, so it is currently impossible to boot the kernel, until the loongarch specific portions get accepted into the UEFI subsystem - The drivers/irqchip/irq-loongson-*.c drivers are shared with the the MIPS port, but currently lack support for ACPI based booting, which will get merged through the irqchip subsystem. - Similarly, the drivers/pci/controller/pci-loongson.c needs to be modified for ACPI support, which will be merged through the PCI subsystem. While the port cannot actually be used before all the above are merged, having it in 5.19 helps to establish the user space ABI for the libc ports to build on, and to help any treewide changes in the mainline kernel get applied here as well.

The {pid,uid}_t fields of struct binder_transaction were recently replaced to use kernel types in commit 169adc2b6b3c ("android/binder.h: add linux/android/binder(fs).h to UAPI compile-test coverage"). However, using __kernel_uid_t here breaks backwards compatibility in architectures using 16-bits for this type, since glibc and some others still expect a 32-bit uid_t. Instead, let's use __kernel_uid32_t which avoids this compatibility problem.

2022-05-31vdpa: Add support for querying vendor statisticsEli Cohen1-0/+6
Allows to read vendor statistics of a vdpa device. The specific statistics data are received from the upstream driver in the form of an (attribute name, attribute value) pairs. An example of statistics for mlx5_vdpa device are: received_desc - number of descriptors received by the virtqueue completed_desc - number of descriptors completed by the virtqueue A descriptor using indirect buffers is still counted as 1. In addition, N chained descriptors are counted correctly N times as one would expect. A new callback was added to vdpa_config_ops which provides the means for the vdpa driver to return statistics results. The interface allows for reading all the supported virtqueues, including the control virtqueue if it exists. Below are some examples taken from mlx5_vdpa which are introduced in the following patch: 1. Read statistics for the virtqueue at index 1 $ vdpa dev vstats show vdpa-a qidx 1 vdpa-a: queue_type tx queue_index 1 received_desc 3844836 completed_desc 3844836 2. Read statistics for the virtqueue at index 32 $ vdpa dev vstats show vdpa-a qidx 32 vdpa-a: queue_type control_vq queue_index 32 received_desc 62 completed_desc 62 3. Read statisitics for the virtqueue at index 0 with json output $ vdpa -j dev vstats show vdpa-a qidx 0 {"vstats":{"vdpa-a":{ "queue_type":"rx","queue_index":0,"name":"received_desc","value":417776,\ "name":"completed_desc","value":417548}}} 4.

2022-05-31net/ipv6: Expand and rename accept_unsolicited_na to accept_untracked_naArun Ajith S1-1/+1
RFC 9131 changes default behaviour of handling RX of NA messages when the corresponding entry is absent in the neighbour cache. The current implementation is limited to accept just unsolicited NAs. However, the RFC is more generic where it also accepts solicited NAs. Both types should result in adding a STALE entry for this case. Expand accept_untracked_na behaviour to also accept solicited NAs to be compliant with the RFC and rename the sysctl knob to accept_untracked_na.

2022-05-31io_uring: let IORING_OP_FILES_UPDATE support choosing fixed file slotsXiaoguang Wang1-0/+6
One big issue with the file registration feature is that it needs user space apps to maintain free slot info about io_uring's fixed file table, which really is a burden for development. io_uring now supports choosing free file slot for user space apps by using IORING_FILE_INDEX_ALLOC flag in accept, open, and socket operations, but they need the app to use direct accept or direct open, which not all apps are prepared to use yet. To support apps that still need real fds, make use of the registration feature easier. Let IORING_OP_FILES_UPDATE support choosing fixed file slots, which will store picked fixed files slots in fd array and let cqe return the number of slots allocated.

git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl Pull cxl updates from Dan Williams: "Compute Express Link (CXL) updates for this cycle. The highlight is new driver-core infrastructure and CXL subsystem changes for allowing lockdep to validate device_lock() usage. Thanks to PeterZ for setting me straight on the current capabilities of the lockdep API, and Greg acked it as well. On the CXL ACPI side this update adds support for CXL _OSC so that platform firmware knows that it is safe to still grant Linux native control of PCIe hotplug and error handling in the presence of CXL devices. A circular dependency problem was discovered between suspend and CXL memory for cases where the suspend image might be stored in CXL memory where that image also contains the PCI register state to restore to re-enable the device. Disable suspend for now until an architecture is defined to clarify that conflict. Lastly a collection of reworks, fixes, and cleanups to the CXL subsystem where support for snooping mailbox commands and properly handling the "mem_enable" flow are the highlights. Summary: - Add driver-core infrastructure for lockdep validation of device_lock(), and fixup a deadlock report that was previously hidden behind the 'lockdep no validate' policy. - Add CXL _OSC support for claiming native control of CXL hotplug and error handling. - Disable suspend in the presence of CXL memory unless and until a protocol is identified for restoring PCI device context from memory hosted on CXL PCI devices. - Add support for snooping CXL mailbox commands to protect against inopportune changes, like set-partition with the 'immediate' flag set. - Rework how the driver detects legacy CXL 1.1 configurations (CXL DVSEC / 'mem_enable') before enabling new CXL 2.0 decode configurations (CXL HDM Capability). - Miscellaneous cleanups and fixes from -next exposure" * tag 'cxl-for-5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl: (47 commits) cxl/port: Enable HDM Capability after validating DVSEC Ranges cxl/port: Reuse 'struct cxl_hdm' context for hdm init cxl/port: Move endpoint HDM Decoder Capability init to port driver cxl/pci: Drop @info argument to cxl_hdm_decode_init() cxl/mem: Merge cxl_dvsec_ranges() and cxl_hdm_decode_init() cxl/mem: Skip range enumeration if mem_enable clear cxl/mem: Consolidate CXL DVSEC Range enumeration in the core cxl/pci: Move cxl_await_media_ready() to the core cxl/mem: Validate port connectivity before dvsec ranges cxl/mem: Fix cxl_mem_probe() error exit cxl/pci: Drop wait_for_valid() from cxl_await_media_ready() cxl/pci: Consolidate wait_for_media() and wait_for_media_ready() cxl/mem: Drop mem_enabled check from wait_for_media() nvdimm: Fix firmware activation deadlock scenarios device-core: Kill the lockdep_mutex nvdimm: Drop nd_device_lock() ACPI: NFIT: Drop nfit_device_lock() nvdimm: Replace lockdep_mutex with local lock classes cxl: Drop cxl_device_lock() cxl/acpi: Add root device lockdep validation ...
