git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci
Pull pci updates from Bjorn Helgaas:
"Enumeration:
- Allow TLP Processing Hints to be enabled for RCiEPs (George Abraham
P)
- Enable AtomicOps only if we know the Root Port supports them (Gerd
Bayer)
- Don't enable AtomicOps for RCiEPs since none of them need Atomic
Ops and we can't tell whether the Root Complex would support them
(Gerd Bayer)
- Leave Precision Time Measurement disabled until a driver enables it
to avoid PCIe errors (Mika Westerberg)
- Make pci_set_vga_state() fail if bridge doesn't support VGA
routing, i.e., PCI_BRIDGE_CTL_VGA is not writable, and return
errors to vga_get() callers including userspace via
/dev/vga_arbiter (Simon Richter)
- Validate max-link-speed from DT in j721e, brcmstb, mediatek-gen3,
rzg3s drivers (where the actual controller constraints are known),
and remove validation from the generic OF DT accessor (Hans Zhang)
- Remove pc110pad driver (no longer useful after 486 CPU support
removed) and no_pci_devices() (pc110pad was the last user) (Dmitry
Torokhov, Heiner Kallweit)
Resource management:
- Prevent assigning space to unimplemented bridge windows; previously
we mistakenly assumed prefetchable window existed and assigned
space and put a BAR there (Ahmed Naseef)
- Avoid shrinking bridge windows to fit in the initial Root Port
window; fixes one problem with devices with large BARs connected
via switches, e.g., Thunderbolt (Ilpo Järvinen)
- Pass full extent of empty space, not just the aligned space, to
resource_alignf callback so free space before the requested
alignment can be used (Ilpo Järvinen)
- Place small resources before larger ones for better utilization of
address space (Ilpo Järvinen)
- Fix alignment calculation for resource size larger than align,
e.g., bridge windows larger than the 1MB required alignment (Ilpo
Järvinen)
Reset:
- Update slot handling so all ARI functions are treated as being in
the same slot. They're all reset by Secondary Bus Reset, but
previously drivers of ARI functions that appeared to be on a
non-zero device weren't notified and fatal hardware errors could
result (Keith Busch)
- Make sysfs reset_subordinate hotplug safe to avoid spurious hotplug
events (Keith Busch)
- Hide Secondary Bus Reset ('bus') from sysfs reset_methods if masked
by CXL because it has no effect (Vidya Sagar)
- Avoid FLR for AMD NPU device, where it causes the device to hang
(Lizhi Hou)
Error handling:
- Clear only error bits in PCIe Device Status to avoid accidentally
clearing Emergency Power Reduction Detected (Shuai Xue)
- Check for AER errors even in devices without drivers (Lukas Wunner)
- Initialize ratelimit info so DPC and EDR paths log AER error
information (Kuppuswamy Sathyanarayanan)
Power control:
- Add UPD720201/UPD720202 USB 3.0 xHCI Host Controller .compatible so
generic pwrctrl driver can control it (Neil Armstrong)
Hotplug:
- Set LED_HW_PLUGGABLE for NPEM hotplug-capable ports so LED core
doesn't complain when setting brightness fails because the endpoint
is gone (Richard Cheng)
Peer-to-peer DMA:
- Allow wildcards in list of host bridges that support peer-to-peer
DMA between hierarchy domains and add all Google SoCs (Jacob
Moroni)
Endpoint framework:
- Advertise dynamic inbound mapping support in pci-epf-test and
update host pci_endpoint_test to skip doorbell testing if not
advertised by endpoint (Koichiro Den)
- Return 0, not remaining timeout, when MHI eDMA ops complete so
mhi_ep_ring_add_element() doesn't interpret non-zero as failure
(Daniel Hodges)
- Remove vntb and ntb duplicate resource teardown that leads to oops
when .allow_link() fails or .drop_link() is called (Koichiro Den)
- Disable vntb delayed work before clearing BAR mappings and
doorbells to avoid oops caused by doing the work after resources
have been torn down (Koichiro Den)
- Add a way to describe reserved subregions within BARs, e.g.,
platform-owned fixed register windows, and use it for the RK3588
BAR4 DMA ctrl window (Koichiro Den)
- Add BAR_DISABLED for BARs that will never be available to an EPF
driver, and change some BAR_RESERVED annotations to BAR_DISABLED
(Niklas Cassel)
- Add NTB .get_dma_dev() callback for cases where DMA API requires a
different device, e.g., vNTB devices (Koichiro Den)
- Add reserved region types for MSI-X Table and PBA so Endpoint
controllers can them as describe hardware-owned regions in a
BAR_RESERVED BAR (Manikanta Maddireddy)
- Make Tegra194/234 BAR0 programmable and remove 1MB size limit
(Manikanta Maddireddy)
- Expose Tegra BAR2 (MSI-X) and BAR4 (DMA) as 64-bit BAR_RESERVED
(Manikanta Maddireddy)
- Add Tegra194 and Tegra234 device table entries to pci_endpoint_test
(Manikanta Maddireddy)
- Skip the BAR subrange selftest if there are not enough inbound
window resources to run the test (Christian Bruel)
New native PCIe controller drivers:
- Add DT binding and driver for Andes QiLai SoC PCIe host controller
(Randolph Lin)
- Add DT binding and driver for ESWIN PCIe Root Complex (Senchuan
Zhang)
Baikal T-1 PCIe controller driver:
- Remove driver since it never quite became usable (Andy Shevchenko)
Cadence PCIe controller driver:
- Implement byte/word config reads with dword (32-bit) reads because
some Cadence controllers don't support sub-dword accesses (Aksh
Garg)
CIX Sky1 PCIe controller driver:
- Add 'power-domains' to DT binding for SCMI power domain (Gary Yang)
Freescale i.MX6 PCIe controller driver:
- Add i.MX94 and i.MX943 to fsl,imx6q-pcie-ep DT binding (Richard
Zhu)
- Delay instead of polling for L2/L3 Ready after PME_Turn_off when
suspending i.MX6SX because LTSSM registers are inaccessible
(Richard Zhu)
- Separate PERST# assertion (for resetting endpoints) from core reset
(for resetting the RC itself) to prepare for new DTs with PERST#
GPIO in per-Root Port nodes (Sherry Sun)
- Retain Root Port MSI capability on i.MX7D, i.MX8MM, and i.MX8MQ so
MSI from downstream devices will work (Richard Zhu)
- Fix i.MX95 reference clock source selection when internal refclk is
used (Franz Schnyder)
Freescale Layerscape PCIe controller driver:
- Allow building as a removable module (Sascha Hauer)
MediaTek PCIe Gen3 controller driver:
- Use dev_err_probe() to simplify error paths and make deferred probe
messages visible in /sys/kernel/debug/devices_deferred (Chen-Yu
Tsai)
- Power off device if setup fails (Chen-Yu Tsai)
- Integrate new pwrctrl API to enable power control for WiFi/BT
adapters on mainboard or in PCIe or M.2 slots (Chen-Yu Tsai)
NVIDIA Tegra194 PCIe controller driver:
- Poll less aggressively and non-atomically for PME_TO_Ack during
transition to L2 (Vidya Sagar)
- Disable LTSSM after transition to Detect on surprise link down to
stop toggling between Polling and Detect (Manikanta Maddireddy)
- Don't force the device into the D0 state before L2 when suspending
or shutting down the controller (Vidya Sagar)
- Disable PERST# IRQ only in Endpoint mode because it's not
registered in Root Port mode (Manikanta Maddireddy)
- Handle 'nvidia,refclk-select' as optional (Vidya Sagar)
- Disable direct speed change in Endpoint mode so link speed change
is controlled by the host (Vidya Sagar)
- Set LTR values before link up to avoid bogus LTR messages with 0
latency (Vidya Sagar)
- Allow system suspend when the Endpoint link is down (Vidya Sagar)
- Use DWC IP core version, not Tegra custom values, to avoid DWC core
version check warnings (Manikanta Maddireddy)
- Apply ECRC workaround to devices based on DesignWare 5.00a as well
as 4.90a (Manikanta Maddireddy)
- Disable PM Substate L1.2 in Endpoint mode to work around Tegra234
erratum (Vidya Sagar)
- Delay post-PERST# cleanup until core is powered on to avoid CBB
timeout (Manikanta Maddireddy)
- Assert CLKREQ# so switches that forward it to their downstream side
can bring up those links successfully (Vidya Sagar)
- Calibrate pipe to UPHY for Endpoint mode to reset stale PLL state
from any previous bad link state (Vidya Sagar)
- Remove IRQF_ONESHOT flag from Endpoint interrupt registration so
DMA driver and Endpoint controller driver can share the interrupt
line (Vidya Sagar)
- Enable DMA interrupt to support DMA in both Root Port and Endpoint
modes (Vidya Sagar)
- Enable hardware link retraining after link goes down in Endpoint
mode (Vidya Sagar)
- Add DT binding and driver support for core clock monitoring (Vidya
Sagar)
Qualcomm PCIe controller driver:
- Advertise 'Hot-Plug Capable' and set 'No Command Completed Support'
since Qcom Root Ports support hotplug events like DL_Up/Down and
can accept writes to Slot Control without delays between writes
(Krishna Chaitanya Chundru)
Renesas R-Car PCIe controller driver:
- Mark Endpoint BAR0 and BAR2 as Resizable (Koichiro Den)
- Reduce EPC BAR alignment requirement to 4K (Koichiro Den)
Renesas RZ/G3S PCIe controller driver:
- Add RZ/G3E to DT binding and to driver (John Madieu)
- Assert (not deassert) resets in probe error path (John Madieu)
- Assert resets in suspend path in reverse order they were deasserted
during probe (John Madieu)
- Rework inbound window algorithm to prevent mapping more than
intended region and enforce alignment on size, to prepare for
RZ/G3E support (John Madieu)

changes (Shawn Lin)
- Trace LTSSM events collected by the dw-rockchip debug FIFO (Shawn
Lin)
SOPHGO PCIe controller driver:
- Disable ASPM L0s and L1 on Sophgo 2042 PCIe Root Ports that
advertise support for them (Yao Zi)

- Set Endpoint MSI-X Table Size in the correct function of a
multi-function device when configuring MSI-X, not in Function 0
(Aksh Garg)
- Set Max Link Width and Max Link Speed for all functions of a
multi-function device, not just Function 0 (Aksh Garg)

Pull networking updates from Jakub Kicinski:
"Core & protocols:
- Support HW queue leasing, allowing containers to be granted access
to HW queues for zero-copy operations and AF_XDP
- Number of code moves to help the compiler with inlining. Avoid
output arguments for returning drop reason where possible
- Rework drop handling within qdiscs to include more metadata about
the reason and dropping qdisc in the tracepoints
- Remove the rtnl_lock use from IP Multicast Routing
- Pack size information into the Rx Flow Steering table pointer
itself. This allows making the table itself a flat array of u32s,
thus making the table allocation size a power of two
- Report TCP delayed ack timer information via socket diag
- Add ip_local_port_step_width sysctl to allow distributing the
randomly selected ports more evenly throughout the allowed space
- Add support for per-route tunsrc in IPv6 segment routing
- Start work of switching sockopt handling to iov_iter
- Improve dynamic recvbuf sizing in MPTCP, limit burstiness and avoid
buffer size drifting up
- Support MSG_EOR in MPTCP
- Add stp_mode attribute to the bridge driver for STP mode selection.
This addresses concerns about call_usermodehelper() usage
- Remove UDP-Lite support (as announced in 2023)
- Remove support for building IPv6 as a module. Remove the now
unnecessary function calling indirection
Cross-tree stuff:
- Move Michael MIC code from generic crypto into wireless, it's
considered insecure but some WiFi networks still need it
Netfilter:
- Switch nft_fib_ipv6 module to no longer need temporary dst_entry
object allocations by using fib6_lookup() + RCU.
Florian W reports this gets us ~13% higher packet rate
- Convert IPVS's global __ip_vs_mutex to per-net service_mutex and
switch the service tables to be per-net. Convert some code that
walks the service lists to use RCU instead of the service_mutex
- Add more opinionated input validation to lower security exposure
- Make IPVS hash tables to be per-netns and resizable
Wireless:
- Finished assoc frame encryption/EPPKE/802.1X-over-auth
- Radar detection improvements
- Add 6 GHz incumbent signal detection APIs
- Multi-link support for FILS, probe response templates and client
probing
- New APIs and mac80211 support for NAN (Neighbor Aware Networking,
aka Wi-Fi Aware) so less work must be in firmware
Driver API:
- Add numerical ID for devlink instances (to avoid having to create
fake bus/device pairs just to have an ID). Support shared devlink
instances which span multiple PFs
- Add standard counters for reporting pause storm events (implement
in mlx5 and fbnic)
- Add configuration API for completion writeback buffering (implement
in mana)
- Support driver-initiated change of RSS context sizes
- Support DPLL monitoring input frequency (implement in zl3073x)

Pull bpf updates from Alexei Starovoitov:
- Welcome new BPF maintainers: Kumar Kartikeya Dwivedi, Eduard
Zingerman while Martin KaFai Lau reduced his load to Reviwer.
- Lots of fixes everywhere from many first time contributors. Thank you
All.
- Diff stat is dominated by mechanical split of verifier.c into
multiple components:
- backtrack.c: backtracking logic and jump history
- states.c: state equivalence
- cfg.c: control flow graph, postorder, strongly connected
components
- liveness.c: register and stack liveness
- fixups.c: post-verification passes: instruction patching, dead
code removal, bpf_loop inlining, finalize fastcall
8k line were moved. verifier.c still stands at 20k lines.
Further refactoring is planned for the next release.
- Replace dynamic stack liveness with static stack liveness based on
data flow analysis.
This improved the verification time by 2x for some programs and
equally reduced memory consumption. New logic is in liveness.c and
supported by constant folding in const_fold.c (Eduard Zingerman,
Alexei Starovoitov)
- Introduce BTF layout to ease addition of new BTF kinds (Alan Maguire)
- Use kmalloc_nolock() universally in BPF local storage (Amery Hung)

Pull arm64 updates from Catalin Marinas:
"The biggest changes are MPAM enablement in drivers/resctrl and new PMU
support under drivers/perf.
On the core side, FEAT_LSUI lets futex atomic operations with EL0
permissions, avoiding PAN toggling.
The rest is mostly TLB invalidation refactoring, further generic entry
work, sysreg updates and a few fixes.
Core features:
- Add support for FEAT_LSUI, allowing futex atomic operations without
toggling Privileged Access Never (PAN)
- Further refactor the arm64 exception handling code towards the
generic entry infrastructure
- Optimise __READ_ONCE() with CONFIG_LTO=y and allow alias analysis
through it
Memory management:
- Refactor the arm64 TLB invalidation API and implementation for
better control over barrier placement and level-hinted invalidation
- Enable batched TLB flushes during memory hot-unplug
- Fix rodata=full block mapping support for realm guests (when
BBML2_NOABORT is available)
Perf and PMU:
- Add support for a whole bunch of system PMUs featured in NVIDIA's
Tegra410 SoC (cspmu extensions for the fabric and PCIe, new drivers
for CPU/C2C memory latency PMUs)
- Clean up iomem resource handling in the Arm CMN driver
- Fix signedness handling of AA64DFR0.{PMUVer,PerfMon}
MPAM (Memory Partitioning And Monitoring):
- Add architecture context-switch and hiding of the feature from KVM
- Add interface to allow MPAM to be exposed to user-space using
resctrl
- Add errata workaround for some existing platforms
- Add documentation for using MPAM and what shape of platforms can
use resctrl
Miscellaneous:
- Check DAIF (and PMR, where relevant) at task-switch time
- Skip TFSR_EL1 checks and barriers in synchronous MTE tag check mode
(only relevant to asynchronous or asymmetric tag check modes)
- Remove a duplicate allocation in the kexec code
- Remove redundant save/restore of SCS SP on entry to/from EL0
- Generate the KERNEL_HWCAP_ definitions from the arm64 hwcap
descriptions
- Add kselftest coverage for cmpbr_sigill()

Pull x86 SEV updates from Borislav Petkov:
- Change the SEV host code handling of when SNP gets enabled in order
to allow the machine to claim SNP-related resources only when SNP
guests are really going to be launched. The user requests this by
loading the ccp module and thus it controls when SNP initialization
is done
So export an API which module code can call and do the necessary SNP
setup only when really needed
- Drop an unnecessary write-back and invalidate operation that was
being performed too early, since the ccp driver already issues its
own at the correct point in the initialization sequence
- Drop the hotplug callbacks for enabling SNP on newly onlined CPUs,
which were both architecturally unsound (the firmware rejects
initialization if any CPU lacks the required configuration) and buggy
(the MFDM SYSCFG MSR bit was not being set)

pre_exit
wg_netns_pre_exit() manually acquires rtnl_lock() inside the
pernet .pre_exit callback. This causes a hung task when another
thread holds rtnl_mutex - the cleanup_net workqueue (or the
setup_net failure rollback path) blocks indefinitely in
wg_netns_pre_exit() waiting to acquire the lock.
Convert to .exit_rtnl, introduced in commit 7a60d91c690b ("net:
Add ->exit_rtnl() hook to struct pernet_operations."), where the
framework already holds RTNL and batches all callbacks under a
single rtnl_lock()/rtnl_unlock() pair, eliminating the contention
window.
The rcu_assign_pointer(wg->creating_net, NULL) is safe to move
from .pre_exit to .exit_rtnl (which runs after synchronize_rcu())
because all RCU readers of creating_net either use maybe_get_net()
- which returns NULL for a dying namespace with zero refcount - or
access net->user_ns which remains valid throughout the entire
ops_undo_list sequence.

Pull timer core updates from Thomas Gleixner:
- A rework of the hrtimer subsystem to reduce the overhead for
frequently armed timers, especially the hrtick scheduler timer:
- Better timer locality decision
- Simplification of the evaluation of the first expiry time by
keeping track of the neighbor timers in the RB-tree by providing
a RB-tree variant with neighbor links. That avoids walking the
RB-tree on removal to find the next expiry time, but even more
important allows to quickly evaluate whether a timer which is
rearmed changes the position in the RB-tree with the modified
expiry time or not. If not, the dequeue/enqueue sequence which
both can end up in rebalancing can be completely avoided.
- Deferred reprogramming of the underlying clock event device. This
optimizes for the situation where a hrtimer callback sets the
need resched bit. In that case the code attempts to defer the
re-programming of the clock event device up to the point where
the scheduler has picked the next task and has the next hrtick
timer armed. In case that there is no immediate reschedule or
soft interrupts have to be handled before reaching the reschedule
point in the interrupt entry code the clock event is reprogrammed
in one of those code paths to prevent that the timer becomes
stale.
- Support for clocksource coupled clockevents
The TSC deadline timer is coupled to the TSC. The next event is
programmed in TSC time. Currently this is done by converting the
CLOCK_MONOTONIC based expiry value into a relative timeout,
converting it into TSC ticks, reading the TSC adding the delta
ticks and writing the deadline MSR.
As the timekeeping core has the conversion factors for the TSC
already, the whole back and forth conversion can be completely
avoided. The timekeeping core calculates the reverse conversion
factors from nanoseconds to TSC ticks and utilizes the base
timestamps of TSC and CLOCK_MONOTONIC which are updated once per
tick. This allows a direct conversion into the TSC deadline value
without reading the time and as a bonus keeps the deadline
conversion in sync with the TSC conversion factors, which are
updated by adjtimex() on systems with NTP/PTP enabled.
- Allow inlining of the clocksource read and clockevent write
functions when they are tiny enough, e.g. on x86 RDTSC and WRMSR.
With all those enhancements in place a hrtick enabled scheduler
provides the same performance as without hrtick. But also other
hrtimer users obviously benefit from these optimizations.
- Robustness improvements and cleanups of historical sins in the
hrtimer and timekeeping code.
- Rewrite of the clocksource watchdog.
The clocksource watchdog code has over time reached the state of an
impenetrable maze of duct tape and staples. The original design,
which was made in the context of systems far smaller than today, is
based on the assumption that the to be monitored clocksource (TSC)
can be trivially compared against a known to be stable clocksource
(HPET/ACPI-PM timer).
Over the years this rather naive approach turned out to have major
flaws. Long delays between the watchdog invocations can cause wrap
arounds of the reference clocksource. The access to the reference
clocksource degrades on large multi-sockets systems dure to
interconnect congestion. This has been addressed with various
heuristics which degraded the accuracy of the watchdog to the point
that it fails to detect actual TSC problems on older hardware which
exposes slow inter CPU drifts due to firmware manipulating the TSC to
hide SMI time.
The rewrite addresses this by:
- Restricting the validation against the reference clocksource to
the boot CPU which is usually closest to the legacy block which
contains the reference clocksource (HPET/ACPI-PM).
- Do a round robin validation betwen the boot CPU and the other
CPUs based only on the TSC with an algorithm similar to the TSC
synchronization code during CPU hotplug.
- Being more leniant versus remote timeouts
- The usual tiny fixes, cleanups and enhancements all over the place

Pull core irq updates from Thomas Gleixner:
- Invoke add_interrupt_randomness() in handle_percpu_devid_irq() and
cleanup the workaround in the Hyper-V driver, which would now invoke
it twice on ARM64. Removing it from the driver requires to add it to
the x86 system vector entry point
- Remove the pointles cpu_read_lock() around reading CPU possible mask,
which is read only after init
- Add documentation for the interaction between device tree bindings
and the interrupt type defines in irq.h

loongarch

Add the following PPE configuration in airoha_ppe_hw_init routine:
- 6RD hw offloading is currently not supported by Netfilter flowtable.
Disable explicitly PPE 6RD offloading in order to prevent PPE to learn
6RD flows and eventually interrupt the traffic.
- Add missing PPE bind rate configuration for L3 and L2 traffic.
PPE bind rate configuration specifies the pps threshold to move a PPE
entry state from UNBIND to BIND. Without this configuration this value
is random.
- Set ageing thresholds to the values used in the vendor SDK in order to
improve connection stability under load and avoid packet loss caused by
fast aging.

EN7581 and AN7583 SoCs have different VIP definitions. Introduce
get_vip_port callback in airoha_eth_soc_data struct in order to take
into account EN7581 and AN7583 VIP register layout and definition
differences.
Introduce nbq parameter in airoha_gdm_port struct. At the moment nbq
is set statically to value previously used in airhoha_set_gdm2_loopback
routine and it will be read from device tree in subsequent patches.

A malicious USB device claiming to be a CDC Phonet modem can overflow
the skb_shared_info->frags[] array by sending an unbounded sequence of
full-page bulk transfers.
Drop the skb and increment the length error when the frag limit is
reached. This matches the same fix that commit f0813bcd2d9d ("net:
wwan: t7xx: fix potential skb->frags overflow in RX path") did for the
t7xx driver.

Pull power sequencing updates from Bartosz Golaszewski:
"For this release we have an extension of the pwrseq-pcie-m2 driver
with support for PCIe M.2 Key E connectors.
The rest of the commits fulfill a supporting role: document the
hardware in DT bindings, provide required serdev helpers (this has
been provided in an immutable branch to Rob Herring so you may see it
in his PR as well) and is followed up by some Kconfig fixes from Arnd.
Summary:
- add support for the PCIe M.2 Key E connectors in pwrseq-pcie-m2
- describe PCIe M.2 Mechanical Key E connectors in DT bindings
- add serdev helpers for looking up devices by OF nodes
- minor serdev core rework to enable support for PCIe M.2 Key E
connectors"
