USB/Thunderbolt changes for 6.16-rc1
Here is the big set of USB and Thunderbolt changes for 6.16-rc1.
Included in here are the following:
- USB offload support for audio devices. I think this takes the
record for the most number of patch series (30+) over the longest
period of time (2+ years) to get merged properly. Many props go to
Wesley Cheng for seeing this effort through, they took a major
out-of-tree hacked-up-monstrosity that was created by multiple
vendors for their specific devices, got it all merged into a
semi-coherent set of changes, and got all of the different major
subsystems to agree on how this should be implemented both with
changes to their code as well as userspace apis, AND wrangled the
hardware companies into agreeing to go forward with this, despite
making them all redo work they had already done in their private
device trees. This feature offers major power savings on embedded
devices where a USB audio stream can continue to flow while the rest
of the system is sleeping, something that devices running on battery
power really care about. There are still some more small tweaks
left to be done here, and those patches are still out for review and
arguing among the different hardware companies, but this is a major
step forward and a great example of how to do upstream development
well.
- small number of thunderbolt fixes and updates, things seem to be
slowing down here (famous last words...)
- xhci refactors and reworking to try to handle some rough corner
cases in some hardware implementations where things don't always
work properly
- typec driver updates
- USB3 power management reworking and updates
- Removal of some old and orphaned UDC gadget drivers that had not
been used in a very long time, dropping over 11 thousand lines from
the tree, always a nice thing, making up for the 12k lines added for
the USB offload feature.
- lots of little updates and fixes in different drivers
All of these have been in linux-next for over 2 weeks, the USB offload
logic has been in there for 8 weeks now, with no reported issues

TTY/Serial changes for 6.16-rc1
Here is the big set of tty and serial driver changes for 6.16-rc1.
A little more churn than normal in this portion of the kernel for this
development cycle, Jiri and Nicholas were busy with cleanups and reviews
and fixes for the vt unicode handling logic which composed most of the
overall work in here.
Major changes are:
- vt unicode changes/reverts/changes from Nicholas. This should help
out a lot with screen readers and others that rely on vt console
support
- lock guard additions to the core tty/serial code to clean up lots of
error handling logic
- 8250 driver updates and fixes
- device tree conversions to yaml
- sh-sci driver updates
- other small cleanups and updates for serial drivers and tty core
portions
All of these have been in linux-next for 2 weeks with no reported issues

drm/nouveau/vfn/r535: Convert comma to semicolon
Replace comma between expressions with semicolons.
Using a ',' in place of a ';' can have unintended side effects.
Although that is not the case here, it is seems best to use ';'
unless ',' is intended.
Found by inspection.
No functional change intended.
Compile tested only.

Power management fixes for 6.16-rc1
Fix three issues introduced into device suspend/resume error paths in the PM core by some of the recent updates. First off, replace list_splice() with list_splice_init() in three places in device suspend error paths to avoid attempting to use an uninitialized list head going forward. Second, rearrange device_resume() to avoid leaking the power.is_suspended device PM flag to the next system suspend/resume cycle where it can confuse rolling back after an error or early wakeup. Finally, add synchronization to dpm_async_resume_children() to avoid resetting the async state mistakenly for devices whose resume callbacks have already been queued up for asynchronous execution in the given device resume phase, which fortunately can happen only if the preceding system suspend transition has been aborted. -----BEGIN PGP SIGNATURE----- iQFGBAABCAAwFiEEcM8Aw/RY0dgsiRUR7l+9nS/U47UFAmhB5vASHHJqd0Byand5 c29ja2kubmV0AAoJEO5fvZ0v1OO1k7IH/RyTAYq/CyilGYCk7/Sd2NgOOrlkhapV s6J3qi13aegcVX1sskJTlgR893Zh1GVIEbNH0DtQz8ExhPb+XIwCxWVIZTaDfogj q40Y7DFn7XIhIH9KkmUab0/PKGdJjxz5EnLfJCFxYjztHC7W4Vx4hnaQyysFXa3t r1hm2e2wWeVKzayFkMUblfXAHX2PSy/JoHZTy71yMDO7XpOui97gr8DsINdXgG6e yCuTQX+3S0bwxnlRL6sHMvvaXMqZZzjVz50uJojP6bQ+7TdppYVIz/y6FVMuOmDd sAoAWz0/rAukjXf3bzqPcHJLvDixBXokFkTfAyMb9a+SKoofTSvULkY= =Wj0P -----END PGP SIGNATURE----- Merge tag 'pm-6.16-rc1-3' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull power management fixes from Rafael Wysocki: "Fix three issues introduced into device suspend/resume error paths in the PM core by some of the recent updates.

ARM fixes for 6.16-rc1
- fix arch_memremap_can_ram_remap() which incorrectly passed a PFN to memblock_is_map_memory rather than the actual address. - "Disallow kernel mode NEON when IRQs are disabled" - this needs a better explanation. "To avoid having to preserve/restore kernel mode NEON state when such a softirq is taken softirqs are now disabled when using the NEON from task context." should explain that it's nested kernel mode. In other words, softirqs from user mode are fine, because the context will be preserved. softirqs from kernel mode may be from a context that has already saved the user NEON state, and thus we would need to preserve the NEON state for the parent kernel mode context, and this we don't allow. The problem occurs when the kernel context disables hard IRQs, and then uses NEON. When it's finished, and restores the userspace NEON state, we call local_bh_enable() with hard IRQs disabled, which causes a warning. This commit addresses that by disallowing the use of NEON with hard IRQs disabled. https://lore.kernel.org/all/20250516231858.27899-4-ebiggers@kernel.org/T/#m104841b6e9346b1814c8b0fb9f2340551b0cd3e8 has some further context. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEuNNh8scc2k/wOAE+9OeQG+StrGQFAmg9k5MACgkQ9OeQG+St rGTsIg//R8AysyZIHWCzO+j7UFZPQ+jUZ0Qf0NMA3Ss/Bh724BtDWIMRo30/ADtX nwJhGnFVenr9jdGuUBmE8R25QyfZIz2U45hGVqUgSL9W96A8PPsuaR7oXhvezq68 Wj+UUTzem4l1bgK416qEROPgY/dtYCL5AbPA+SdH+LSMvS9phkhT6PkGJRC14tZ9 kLNR4PyA9/DC6N6wIU8v9pWezSoOBn/ISBpb67BB0OzZPlmgoJJOXbSNzIHaJc4C YjjJCHRmZL2w/U4HyEc8qXyHMPggEKtDas6mwrpxV/fjoReC/vk3tvuRxy1Mt1Ny BIIOA/Hauz8O9+aqfdqABK92tMiLx7NA9bWQDndIisfD/nRFyrpFDUbw1+d4EemU qzDmKSNWK9nsC28kE8F5M4XLacHu4AQN10Ktjr5LXGoMmPfDz0xssd2uDJkbL4Zq wHVea4HPX8Ykrv6yg+iRZp54z25+ckD+kf93zhutabaa/zVdAHAU9Lk/Uqm2G1R2 5huER0vvLJF3+mYu9mRjodssOUsEVwPbBuGiwJ7DY2a6faexuJv/sU5ZyHhwHb/B TjaYbektcllYWly+KN33XzZXuVVpY9DbRq/2MCFbxMYjHxGjj7QiytTm8tI6VX26 yi8CQ+8/0SXoBPaDjb2y4n6qIxcjiBcdQ8DxDbA9Od0glzJQUhE= =V4ew -----END PGP SIGNATURE----- Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rmk/linux Pull ARM fixes from Russell King: - Fix arch_memremap_can_ram_remap() which incorrectly passed a PFN to memblock_is_map_memory rather than the actual address. - Disallow kernel mode NEON when IRQs are disabled Explanation: "To avoid having to preserve/restore kernel mode NEON state when such a softirq is taken softirqs are now disabled when using the NEON from task context." should explain that it's nested kernel mode.

drm/xe/pxp: Clarify PXP queue creation behavior if PXP is not ready
The expected flow of operations when using PXP is to query the PXP status and wait for it to transition to "ready" before attempting to create an exec_queue. This flow is followed by the Mesa driver, but there is no guarantee that an incorrectly coded (or malicious) app will not attempt to create the queue first without querying the status. Therefore, we need to clarify what the expected behavior of the queue creation ioctl is in this scenario. Currently, the ioctl always fails with an -EBUSY code no matter the error, but for consistency it is better to distinguish between "failed to init" (-EIO) and "not ready" (-EBUSY), the same way the query ioctl does. Note that, while this is a change in the return code of an ioctl, the behavior of the ioctl in this particular corner case was not clearly spec'd, so no one should have been relying on it (and we know that Mesa, which is the only known userspace for this, didn't). v2: Minor rework of the doc (Rodrigo) Fixes: |

drm/xe/sched: stop re-submitting signalled jobs
Customer is reporting a really subtle issue where we get random DMAR
faults, hangs and other nasties for kernel migration jobs when stressing
stuff like s2idle/s3/s4. The explosions seems to happen somewhere
after resuming the system with splats looking something like:
PM: suspend exit
rfkill: input handler disabled
xe 0000:00:02.0: [drm] GT0: Engine reset: engine_class=bcs, logical_mask: 0x2, guc_id=0
xe 0000:00:02.0: [drm] GT0: Timedout job: seqno=24496, lrc_seqno=24496, guc_id=0, flags=0x13 in no process [-1]
xe 0000:00:02.0: [drm] GT0: Kernel-submitted job timed out
The likely cause appears to be a race between suspend cancelling the
worker that processes the free_job()'s, such that we still have pending
jobs to be freed after the cancel. Following from this, on resume the
pending_list will now contain at least one already complete job, but it
looks like we call drm_sched_resubmit_jobs(), which will then call
run_job() on everything still on the pending_list. But if the job was
already complete, then all the resources tied to the job, like the bb
itself, any memory that is being accessed, the iommu mappings etc. might
be long gone since those are usually tied to the fence signalling.
This scenario can be seen in ftrace when running a slightly modified
xe_pm IGT (kernel was only modified to inject artificial latency into
free_job to make the race easier to hit):
xe_sched_job_run: dev=0000:00:02.0, fence=0xffff888276cc8540, seqno=0, lrc_seqno=0, gt=0, guc_id=0, batch_addr=0x000000146910 ...
xe_exec_queue_stop: dev=0000:00:02.0, 3:0x2, gt=0, width=1, guc_id=0, guc_state=0x0, flags=0x13
xe_exec_queue_stop: dev=0000:00:02.0, 3:0x2, gt=0, width=1, guc_id=1, guc_state=0x0, flags=0x4
xe_exec_queue_stop: dev=0000:00:02.0, 4:0x1, gt=1, width=1, guc_id=0, guc_state=0x0, flags=0x3
xe_exec_queue_stop: dev=0000:00:02.0, 1:0x1, gt=1, width=1, guc_id=1, guc_state=0x0, flags=0x3
xe_exec_queue_stop: dev=0000:00:02.0, 4:0x1, gt=1, width=1, guc_id=2, guc_state=0x0, flags=0x3
xe_exec_queue_resubmit: dev=0000:00:02.0, 3:0x2, gt=0, width=1, guc_id=0, guc_state=0x0, flags=0x13
xe_sched_job_run: dev=0000:00:02.0, fence=0xffff888276cc8540, seqno=0, lrc_seqno=0, gt=0, guc_id=0, batch_addr=0x000000146910 ...
.....
xe_exec_queue_memory_cat_error: dev=0000:00:02.0, 3:0x2, gt=0, width=1, guc_id=0, guc_state=0x3, flags=0x13
So the job_run() is clearly triggered twice for the same job, even
though the first must have already signalled to completion during
suspend. We can also see a CAT error after the re-submit.
To prevent this only resubmit jobs on the pending_list that have not yet
signalled.
v2:
- Make sure to re-arm the fence callbacks with sched_start().
v3 (Matt B):
- Stop using drm_sched_resubmit_jobs(), which appears to be deprecated
and just open-code a simple loop such that we skip calling run_job()
on anything already signalled.

drm/xe: Rework eviction rejection of bound external bos
For preempt_fence mode VM's we're rejecting eviction of shared bos during VM_BIND. However, since we do this in the move() callback, we're getting an eviction failure warning from TTM. The TTM callback intended for these things is eviction_valuable(). However, the latter doesn't pass in the struct ttm_operation_ctx needed to determine whether the caller needs this. Instead, attach the needed information to the vm under the vm->resv, until we've been able to update TTM to provide the needed information. And add sufficient lockdep checks to prevent misuse and races. v2: - Fix a copy-paste error in xe_vm_clear_validating() v3: - Fix kerneldoc errors.

drm/xe/vsec: fix CONFIG_INTEL_VSEC dependency
The XE driver can be built with or without VSEC support, but fails to link as
built-in if vsec is in a loadable module:
x86_64-linux-ld: vmlinux.o: in function `xe_vsec_init':
(.text+0x1e83e16): undefined reference to `intel_vsec_register'
The normal fix for this is to add a 'depends on INTEL_VSEC || !INTEL_VSEC',
forcing XE to be a loadable module as well, but that causes a circular
dependency:
symbol DRM_XE depends on INTEL_VSEC
symbol INTEL_VSEC depends on X86_PLATFORM_DEVICES
symbol X86_PLATFORM_DEVICES is selected by DRM_XE
The problem here is selecting a symbol from another subsystem, so change
that as well and rephrase the 'select' into the corresponding dependency.
Since X86_PLATFORM_DEVICES is 'default y', there is no change to
defconfig builds here.

sysfb: Fix screen_info type check for VGA
Use the helper screen_info_video_type() to get the framebuffer
type from struct screen_info. Handle supported values in sorted
switch statement.
Reading orig_video_isVGA is unreliable. On most systems it is a
VIDEO_TYPE_ constant. On some systems with VGA it is simply set
to 1 to signal the presence of a VGA output. See vga_probe() for
an example. Retrieving the screen_info type with the helper
screen_info_video_type() detects these cases and returns the
appropriate VIDEO_TYPE_ constant. For VGA, sysfb creates a device
named "vga-framebuffer".
The sysfb code has been taken from vga16fb, where it likely didn't
work correctly either. With this bugfix applied, vga16fb loads for
compatible vga-framebuffer devices.

video: screen_info: Relocate framebuffers behind PCI bridges
Apply PCI host-bridge window offsets to screen_info framebuffers. Fixes invalid access to I/O memory. Resources behind a PCI host bridge can be relocated by a certain offset in the kernel's CPU address range used for I/O. The framebuffer memory range stored in screen_info refers to the CPU addresses as seen during boot (where the offset is 0). During boot up, firmware may assign a different memory offset to the PCI host bridge and thereby relocating the framebuffer address of the PCI graphics device as seen by the kernel. The information in screen_info must be updated as well. The helper pcibios_bus_to_resource() performs the relocation of the screen_info's framebuffer resource (given in PCI bus addresses). The result matches the I/O-memory resource of the PCI graphics device (given in CPU addresses). As before, we store away the information necessary to later update the information in screen_info itself. Commit |

seg6: Fix validation of nexthop addresses
The kernel currently validates that the length of the provided nexthop
address does not exceed the specified length. This can lead to the
kernel reading uninitialized memory if user space provided a shorter
length than the specified one.
Fix by validating that the provided length exactly matches the specified
one.

The device type for IPv4 GRE is "gre" not "ipgre",

Not sure how I missed this when writing the test, perhaps
because all HW I have access to is on an IPv6-only network.

Tony Nguyen says: ==================== iavf: get rid of the crit lock Przemek Kitszel says: Fix some deadlocks in iavf, and make it less error prone for the future. Patch 1 is simple and independent from the rest. Patches 2, 3, 4 are strictly a refactor, but it enables the last patch to be much smaller. (Technically Jake given his RB tags not knowing I will send it to -net). Patch 5 just adds annotations, this also helps prove last patch to be correct. Patch 6 removes the crit lock, with its unusual try_lock()s. I have more refactoring for scheduling done for -next, to be sent soon. There is a simple test: add VF; decrease number of queueus; remove VF that was way too hard to pass without this series :) * '40GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/net-queue: iavf: get rid of the crit lock iavf: sprinkle netdev_assert_locked() annotations iavf: extract iavf_watchdog_step() out of iavf_watchdog_task() iavf: simplify watchdog_task in terms of adminq task scheduling iavf: centralize watchdog requeueing itself iavf: iavf_suspend(): take RTNL before netdev_lock() ==================== Link: https://patch.msgid.link/20250603171710.2336151-1-anthony.l.nguyen@intel.com Signed-off-by: Jakub Kicinski <kuba@kernel.org> |

wireguard: device: enable threaded NAPI
Enable threaded NAPI by default for WireGuard devices in response to low
performance behavior that we observed when multiple tunnels (and thus
multiple wg devices) are deployed on a single host. This affects any
kind of multi-tunnel deployment, regardless of whether the tunnels share
the same endpoints or not (i.e., a VPN concentrator type of gateway
would also be affected).
The problem is caused by the fact that, in case of a traffic surge that
involves multiple tunnels at the same time, the polling of the NAPI
instance of all these wg devices tends to converge onto the same core,
causing underutilization of the CPU and bottlenecking performance.
This happens because NAPI polling is hosted by default in softirq
context, but the WireGuard driver only raises this softirq after the rx
peer queue has been drained, which doesn't happen during high traffic.
In this case, the softirq already active on a core is reused instead of
raising a new one.
As a result, once two or more tunnel softirqs have been scheduled on
the same core, they remain pinned there until the surge ends.
In our experiments, this almost always leads to all tunnel NAPIs being
handled on a single core shortly after a surge begins, limiting
scalability to less than 3× the performance of a single tunnel, despite
plenty of unused CPU cores being available.
The proposed mitigation is to enable threaded NAPI for all WireGuard
devices. This moves the NAPI polling context to a dedicated per-device
kernel thread, allowing the scheduler to balance the load across all
available cores.
On our 32-core gateways, enabling threaded NAPI yields a ~4× performance
improvement with 16 tunnels, increasing throughput from ~13 Gbps to
~48 Gbps. Meanwhile, CPU usage on the receiver (which is the bottleneck)
jumps from 20% to 100%.
We have found no performance regressions in any scenario we tested.
Single-tunnel throughput remains unchanged.
More details are available in our Netdev paper.
