594740497e dma-buf: Add an API for importing sync files (v10)
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):

 - 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

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.

20e10881a0 dma-buf: Add an API for exporting sync files (v14)
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

2981436374 hte: New subsystem for v5.19-rc1
This contains the new HTE subsystem that has been in the works for a
 couple of months now. The infrastructure provided allows for drivers to
 register as hardware timestamp providers, while consumers will be able
 to request events that they are interested in (such as GPIOs and IRQs)
 to be timestamped by the hardware providers.
 
 Note that this currently supports only one provider, but there seems to
 be enough interest in this functionality and we expect to see more
 drivers added once this is merged.

c6f2f3e2c8 Add partial Loongarch architecture code
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. A gcc-12 based
 tool chains for build testing is now included in
 https://mirrors.edge.kernel.org/pub/tools/crosstool/.
 
 Original description from Huacai Chen at
 https://lore.kernel.org/lkml/20220603072053.35005-1-chenhuacai@loongson.cn/:
 
  "LoongArch is a new RISC ISA, which is a bit like MIPS or RISC-V.
   LoongArch includes a reduced 32-bit version (LA32R), a standard 32-bit

6f9b5ed8ca Char / Misc / Other smaller driver subsystem updates for 5.19-rc1
Here is the large set of char, misc, and other driver subsystem updates
 for 5.19-rc1.  The merge request for this has been delayed as I wanted
 to get lots of linux-next testing due to some late arrivals of changes
 for the habannalabs driver.
 
 Highlights of this merge are:
 	- habanalabs driver updates for new hardware types and fixes and
 	  other updates
 	- IIO driver tree merge which includes loads of new IIO drivers
 	  and cleanups and additions
 	- PHY driver tree merge with new drivers and small updates to
 	  existing ones
 	- interconnect driver tree merge with fixes and updates
 	- soundwire driver tree merge with some small fixes
 	- coresight driver tree merge with small fixes and updates
 	- mhi bus driver tree merge with lots of updates and new device
 	  support
 	- firmware driver updates
 	- fpga driver updates
 	- lkdtm driver updates (with a merge conflict, more on that
 	  below)
 	- extcon driver tree merge with small updates
 	- lots of other tiny driver updates and fixes and cleanups, full
 	  details in the shortlog.
 
 All of these have been in linux-next for almost 2 weeks with no reported
 problems.
 
 Note, there are 3 merge conflicts when merging this with your tree:
 	- MAINTAINERS, should be easy to resolve
 	- drivers/slimbus/qcom-ctrl.c, should be straightforward
 	  resolution
 	- drivers/misc/lkdtm/stackleak.c, not an easy resolution.  This
 	  has been noted in the linux-next tree for a while, and
 	  resolved there, here's a link to the resolution that Stephen
 	  came up with and that Kees says is correct:
 	  	https://lore.kernel.org/r/20220509185344.3fe1a354@canb.auug.org.au
 
 I will be glad to provide a merge point that contains these resolutions
 if that makes things any easier for you.

baf86ac1c9 asm-generic fixes for 5.19, part 1
The header cleanup series from Masahiro Yamada ended up causing
 some regressions in the ABI because of an ambigous uid_t type.
 
 This was only caught after the original patches got merged, but
 at least the fixes are trivial and hopefully complete.

8cc5b03224 binder: fix sender_euid type in uapi header
The {pid,uid}_t fields of struct binder_transaction were recently
replaced to use kernel types in commit 169adc2b6b ("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.

662ce1dc9c delayacct: track delays from write-protect copy
Delay accounting does not track the delay of write-protect copy.  When
tasks trigger many write-protect copys(include COW and unsharing of
anonymous pages[1]), it may spend a amount of time waiting for them.  To
get the delay of tasks in write-protect copy, could help users to evaluate
the impact of using KSM or fork() or GUP.

Also update tools/accounting/getdelays.c:

    / # ./getdelays -dl -p 231

13b00b1356 vdpa: Add support for querying vendor statistics
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. Read statistics for the virtqueue at index 0 with preety json output
$ vdpa -jp 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
        }
    }

3e0b8f529c net/ipv6: Expand and rename accept_unsolicited_na to accept_untracked_na
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.

a7c41b4687 io_uring: let IORING_OP_FILES_UPDATE support choosing fixed file slots
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.

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

   - Disable suspend in the presence of CXL memory unless and until a

16477cdfef asm-generic changes for 5.19
The asm-generic tree contains three separate changes for linux-5.19:
 
 - The h8300 architecture is retired after it has been effectively
   unmaintained for a number of years. This is the last architecture we
   supported that has no MMU implementation, but there are still a few
   architectures (arm, m68k, riscv, sh and xtensa) that support CPUs with
   and without an MMU.
 
 - A series to add a generic ticket spinlock that can be shared by most
   architectures with a working cmpxchg or ll/sc type atomic, including
   the conversion of riscv, csky and openrisc. This series is also a
   prerequisite for the loongarch64 architecture port that will come as
   a separate pull request.
 
 - A cleanup of some exported uapi header files to ensure they can be
   included from user space without relying on other kernel headers.

cc3c470ae4 ARM: driver changes for 5.19
There are minor updates to SoC specific drivers for chips by Rockchip,
 Samsung, NVIDIA, TI, NXP, i.MX, Qualcomm, and Broadcom. Noteworthy
 driver changes include:
 
 - Several conversions of DT bindings to yaml format.
 
 - Renesas adds driver support for R-Car V4H, RZ/V2M and RZ/G2UL SoCs.
 
 - Qualcomm adds a bus driver for the SSC (Snapdragon Sensor Core),
   and support for more chips in the RPMh power domains and the soc-id.
 
 - NXP has a new driver for the HDMI blk-ctrl on i.MX8MP.
 
 - Apple M1 gains support for the on-chip NVMe controller, making it
   possible to finally use the internal disks. This also includes SoC
   drivers for their RTKit IPC and for the SART DMA address filter.
 
 For other subsystems that merge their drivers through the SoC tree,
 we have
 
 - Firmware drivers for the ARM firmware stack including TEE, OP-TEE,
   SCMI and FF-A get a number of smaller updates and cleanups. OP-TEE
   now has a cache for firmware argument structures as an optimization,
   and SCMI now supports the 3.1 version of the specification.
 
 - Reset controller updates to Amlogic, ASpeed, Renesas and ACPI drivers
 
 - Memory controller updates for Tegra, and a few updates for other
   platforms.
