Introduce the GPU debug operations interface.
For ROCm-GDB to extend the GNU Debugger's ability to inspect the AMD GPU
instruction set, provide the necessary interface to allow the debugger
to HW debug-mode set and query exceptions per HSA queue, process or
device.
The runtime_enable interface coordinates exception handling with the
HSA runtime.
Usage is available in the kern docs at uapi/linux/kfd_ioctl.h.

Merge v6.3-rc4 into drm-next

This series adds a deadline hint to fences, so realtime deadlines
such as vblank can be communicated to the fence signaller for power/
frequency management decisions.
This is partially inspired by a trick i915 does, but implemented
via dma-fence for a couple of reasons:
1) To continue to be able to use the atomic helpers
2) To support cases where display and gpu are different drivers
See https://patchwork.freedesktop.org/series/93035/
This does not yet add any UAPI, although this will be needed in
a number of cases:
1) Workloads "ping-ponging" between CPU and GPU, where we don't
want the GPU freq governor to interpret time stalled waiting
for GPU as "idle" time
2) Cases where the compositor is waiting for fences to be signaled
before issuing the atomic ioctl, for example to maintain 60fps
cursor updates even when the GPU is not able to maintain that
framerate.

- uAPI changes:
- Add opcodes to the CS ioctl to allow user to stall/resume specific engines
inside Gaudi2. This is to allow the user to perform power
testing/measurements when training different topologies.
- Expose in the INFO ioctl the amount of device memory that the driver
and f/w reserve for themselves.
- Expose in the INFO ioctl a bit-mask of the available rotator engines
in Gaudi2. This is to align with other engines that are already exposed.
- Expose in the INFO ioctl the register's address of the f/w that should
be used to trigger interrupts from within the user's code running in the
compute engines.
- Add a critical-event bit in the eventfd bitmask so the user will know the
event that was received was critical, and a reset will now occur
- Expose in the INFO ioctl two new opcodes to fetch information on h/w and
f/w events. The events recorded are the events that were reported in the
eventfd.
- New features and improvements:
- Add a dedicated interrupt ID in MSI-X in the device to the notification of
an unexpected user-related event in Gaudi2. Handle it in the driver by
reporting this event.
- Allow the user to fetch the device memory current usage even when the
device is undergoing compute-reset (a reset type that only clears the
compute engines).
- Enable graceful reset mechanism for compute-reset. This will give the
user a few seconds before the device is reset. For example, the user can,
during that time, perform certain device operations (dump data for debug)
or close the device in an orderly fashion.
- Align the decoder with the rest of the engines in regard to notification
to the user about interrupts and in regard to performing graceful reset
when needed (instead of immediate reset).
- Add support for assert interrupt from the TPC engine.
- Get the reset type that is necessary to perform per event from the
auto-generated irq_map array.
- Print the specific reason why a device is still in use when notifying to
the user about it (after the user closed the device's FD).
- Move to threaded IRQ when handling interrupts of workload completions.
- Firmware related fixes:
- Fix RAZWI event handler to match newest f/w version.
- Read error cause register in dma core events because the f/w doesn't
do that.
- Increase maximum time to wait for completion of Gaudi2 reset due to f/w
bug.
- Align to the latest firmware specs.
- Enforce the release order of the compute device and dma-buf.
i.e increment the device file refcount for any dma-buf that was exported
for that device. This will make sure the compute device release function
won't be called until the user closes all the FDs of the relevant
dma-bufs. Without this change, closing the device's FD before/without
closing the dma-buf's FD would always lead to hard-reset of the device.
- Fix a link in the drm documentation to correctly point to the accel section.
- Compilation warnings cleanups
- Misc bug fixes and code cleanups

Merge tag 'net-6.3-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net
Pull networking fixes from Jakub Kicinski:
"Including fixes from netfilter, wifi and ipsec.
A little more changes than usual, but it's pretty normal for us that
the rc3/rc4 PRs are oversized as people start testing in earnest.
Possibly an extra boost from people deploying the 6.1 LTS but that's
more of an unscientific hunch.
Current release - regressions:
- phy: mscc: fix deadlock in phy_ethtool_{get,set}_wol()
- virtio: vsock: don't use skbuff state to account credit
- virtio: vsock: don't drop skbuff on copy failure
- virtio_net: fix page_to_skb() miscalculating the memory size
Current release - new code bugs:
- eth: correct xdp_features after device reconfig
- wifi: nl80211: fix the puncturing bitmap policy
- net/mlx5e: flower:
- fix raw counter initialization
- fix missing error code
- fix cloned flow attribute
- ipa:
- fix some register validity checks
- fix a surprising number of bad offsets
- kill FILT_ROUT_CACHE_CFG IPA register
Previous releases - regressions:
- tcp: fix bind() conflict check for dual-stack wildcard address
- veth: fix use after free in XDP_REDIRECT when skb headroom is small
- ipv4: fix incorrect table ID in IOCTL path
- ipvlan: make skb->skb_iif track skb->dev for l3s mode
- mptcp:
- fix possible deadlock in subflow_error_report
- fix UaFs when destroying unaccepted and listening sockets
- dsa: mv88e6xxx: fix max_mtu of 1492 on 6165, 6191, 6220, 6250, 6290
Previous releases - always broken:
- tcp: tcp_make_synack() can be called from process context, don't
assume preemption is disabled when updating stats
- netfilter: correct length for loading protocol registers
- virtio_net: add checking sq is full inside xdp xmit
- bonding: restore IFF_MASTER/SLAVE flags on bond enslave Ethertype
change
- phy: nxp-c45-tja11xx: fix MII_BASIC_CONFIG_REV bit number
- eth: i40e: fix crash during reboot when adapter is in recovery mode
- eth: ice: avoid deadlock on rtnl lock when auxiliary device
plug/unplug meets bonding
- dsa: mt7530:
- remove now incorrect comment regarding port 5
- set PLL frequency and trgmii only when trgmii is used
- eth: mtk_eth_soc: reset PCS state when changing interface types
Misc:
- ynl: another license adjustment
- move the TCA_EXT_WARN_MSG attribute for tc action"

...
In my previous commit 0349b8779c ("sched: add new attr TCA_EXT_WARN_MSG
to report tc extact message") I didn't notice the tc action use different
enum with filter. So we can't use TCA_EXT_WARN_MSG directly for tc action.
Let's add a TCA_ROOT_EXT_WARN_MSG for tc action specifically and put this
param before going to the TCA_ACT_TAB nest.

I relicensed Netlink spec code to GPL-2.0 OR BSD-3-Clause but
we still put a slightly different license on the uAPI header
than the rest of the code. Use the Linux-syscall-note on all
the specs and all generated code. It's moot for kernel code,
but should not hurt. This way the licenses match everywhere.

The user might want to stall/resume engines to perform power testing
for various scenarios. Because our current
HL_CS_FLAGS_ENGINE_CORE_COMMAND command only handles the engines' cores,
we need to add another opcode for handling entire engine and not just
its core.
The user supplies an array, where each entry holds the engine's ID and
the command to send to the engine. The size of the array is limited
by the number of engines in the ASIC (only Gaudi2 is currently
supported).

Pull btrfs fixes from David Sterba:
"First batch of fixes. Among them there are two updates to sysfs and
ioctl which are not strictly fixes but are used for testing so there's
no reason to delay them.
- fix block group item corruption after inserting new block group
- fix extent map logging bit not cleared for split maps after
dropping range
- fix calculation of unusable block group space reporting bogus
values due to 32/64b division
- fix unnecessary increment of read error stat on write error
- improve error handling in inode update
- export per-device fsid in DEV_INFO ioctl to distinguish seeding
devices, needed for testing
- allocator size classes:
- fix potential dead lock in size class loading logic
- print sysfs stats for the allocation classes"

I was intending to make all the Netlink Spec code BSD-3-Clause
to ease the adoption but it appears that:
- I fumbled the uAPI and used "GPL WITH uAPI note" there
- it gives people pause as they expect GPL in the kernel
As suggested by Chuck re-license under dual. This gives us benefit
of full BSD freedom while fulfilling the broad "kernel is under GPL"
expectations.

Currently user space utilizes dev info ioctl to grab the info of a
certain devid, this includes its device uuid. But the returned info is
not enough to determine if a device is a seed.
Commit a26d60dedf ("btrfs: sysfs: add devinfo/fsid to retrieve actual
fsid from the device") exports the same value in sysfs so this is for
parity with ioctl. Add a new member, fsid, into
btrfs_ioctl_dev_info_args, and populate the member with fsid value.
This should not cause any compatibility problem, following the
combinations:
- Old user space, old kernel
- Old user space, new kernel
User space tool won't even check the new member.
- New user space, old kernel
The kernel won't touch the new member, and user space tool should
zero out its argument, thus the new member is all zero.
User space tool can then know the kernel doesn't support this fsid
reporting, and falls back to whatever they can.
- New user space, new kernel
Go as planned.
Would find the fsid member is no longer zero, and trust its value.

Exports a DMA buf fd of a given KFD buffer handle. This is intended for
being able to import KFD BOs into GEM contexts to leverage the

also be used for the new upstreamable RDMA solution coming to UCX and
RCCL.

Merge tag 'media/v6.3-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media
Pull media updates from Mauro Carvalho Chehab:
- Removal of several VB1-only deprecated drivers: cpia2, fsl-viu, meye,
stkwebcam, tm6000, vpfe_capture and zr364xx
- saa7146 recovered from staging/deprecated. We opted to give ti a
chance, and, instead of deprecating it, the intention is to write
patches migrating it from VB1 to VB2.
- av7110 returned from staging/deprecated/ to staging/ as we're not
planning on dropping it any time soon
- media controller API has gained experimental support for G_ROUTING
and streams API. No drivers use it right now. We're planning to add
one after -rc1, giving some time to experience the API and eventually
have changes during the next development cycle
- New sensor drivers: imx296, imx415, ov8858
- Atomisp had lots of changes, specially on its sensor's interface,
making atomisp sensor drivers closer to normal sensor drivers
- media controller kAPI has gained some helpers to traverse pipelines
- uvcvideo now better support power line control
- lots of bug fixes, cleanups and driver improvements

- Remove redundant resource check in vfio-platform. (Angus Chen)
- Use GFP_KERNEL_ACCOUNT for persistent userspace allocations, allowing
removal of arbitrary kernel limits in favor of cgroup control.
(Yishai Hadas)
- mdev tidy-ups, including removing the module-only build restriction
for sample drivers, Kconfig changes to select mdev support,
documentation movement to keep sample driver usage instructions with
sample drivers rather than with API docs, remove references to
out-of-tree drivers in docs. (Christoph Hellwig)
- Fix collateral breakages from mdev Kconfig changes. (Arnd Bergmann)
- Make mlx5 migration support match device support, improve source
and target flows to improve pre-copy support and reduce downtime.
(Yishai Hadas)
- Convert additional mdev sysfs case to use sysfs_emit(). (Bo Liu)
- Resolve copy-paste error in mdev mbochs sample driver Kconfig.
(Ye Xingchen)
- Avoid propagating missing reset error in vfio-platform if reset
requirement is relaxed by module option. (Tomasz Duszynski)
- Range size fixes in mlx5 variant driver for missed last byte and
stricter range calculation. (Yishai Hadas)
- Fixes to suspended vaddr support and locked_vm accounting, excluding
mdev configurations from the former due to potential to indefinitely
block kernel threads, fix underflow and restore locked_vm on new mm.
(Steve Sistare)
- Update outdated vfio documentation due to new IOMMUFD interfaces in
recent kernels. (Yi Liu)
- Resolve deadlock between group_lock and kvm_lock, finally.
(Matthew Rosato)
- Fix NULL pointer in group initialization error path with IOMMUFD.
