VFIO updates for v7.0-rc1
- Update outdated mdev comment referencing the renamed
mdev_type_add() function. (Julia Lawall)
- Introduce selftest support for IOMMU mapping of PCI MMIO BARs.
(Alex Mastro)
- Relax selftest assertion relative to differences in huge page
handling between legacy (v1) TYPE1 IOMMU mapping behavior and
the compatibility mode supported by IOMMUFD. (David Matlack)
- Reintroduce memory poison handling support for non-struct-page-
backed memory in the nvgrace-gpu variant driver. (Ankit Agrawal)
- Replace dma_buf_phys_vec with phys_vec to avoid duplicate
structure and semantics. (Leon Romanovsky)
- Add missing upstream bridge locking across PCI function reset,
resolving an assertion failure when secondary bus reset is used
to provide that reset. (Anthony Pighin)
- Fixes to hisi_acc vfio-pci variant driver to resolve corner case
issues related to resets, repeated migration, and error injection
scenarios. (Longfang Liu, Weili Qian)
- Restrict vfio selftest builds to arm64 and x86_64, resolving
compiler warnings on 32-bit archs. (Ted Logan)
- Un-deprecate the fsl-mc vfio bus driver as a new maintainer has
stepped up. (Ioana Ciornei)

runtime verifier changes for 7.0:
- Refactor da_monitor to minimise macros Complete refactor of da_monitor.h to reduce reliance on macros generating functions. Use generic static functions and uses the preprocessor only when strictly necessary (e.g. for tracepoint handlers). The change essentially relies on functions with generic names (e.g. da_handle) instead of monitor-specific as well adding the need to define constant (e.g. MONITOR_NAME, MONITOR_TYPE) before including the header rather than calling macros that would define functions. Also adapt monitors and documentation accordingly. - Cleanup DA code generation scripts Clean up functions in dot2c removing reimplementations of trivial library functions (__buff_to_string) and removing some other unused intermediate steps. - Annotate functions with types in the rvgen python scripts - Remove superfluous assignments and cleanup generated code The rvgen scripts generate a superfluous assignment to 0 for enum variables and don't add commas to the last elements, which is against the kernel coding standards. Change the generation process for a better compliance and slightly simpler logic. - Remove superfluous declarations from generated code The monitor container source files contained a declaration and a definition for the rv_monitor variable. The former is superfluous and was removed. - Fix reference to outdated documentation s/da_monitor_synthesis.rst/monitor_synthesis.rst in comment in da_monitor.h -----BEGIN PGP SIGNATURE----- iIoEABYKADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCaY3j9xQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qup5AP0afGb2gr+SOIOu0dIAXjGLg3cbz0C4 J4bDx6H0cdgXywD+Maassm0nKIgDnOBLwtuwL0kEUAxllqn7RCZ2+ARwbAU= =dfCl -----END PGP SIGNATURE----- Merge tag 'trace-rv-v7.0' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull runtime verifier updates from Steven Rostedt: - Refactor da_monitor to minimize macros Complete refactor of da_monitor.h to reduce reliance on macros generating functions.

fsverity updates for 7.0
fsverity cleanups, speedup, and memory usage optimization from
Christoph Hellwig:
- Move some logic into common code
- Fix btrfs to reject truncates of fsverity files
- Improve the readahead implementation
- Store each inode's fsverity_info in a hash table instead of using a
pointer in the filesystem-specific part of the inode.
This optimizes for memory usage in the usual case where most files
don't have fsverity enabled.
- Look up the fsverity_info fewer times during verification, to
amortize the hash table overhead

New features and improvements for the ext4 file system
* Avoid unnecessary cache invadiation in the extent status cache
(es_cache) when adding extents to be cached in the es_cache and we
are not changing the extent tree.
* Add a sysfs parameter, err_report_sec, to control how frequently
to log a warning message that file system inconsistency has been
detected. (Previously we logged the warning message every 24
hours.)
* Avoid unnecessary forced ordered writes when appending to a file
when delayed allocation is enabled.
* Defer splitting unwritten extents to I/O completion to improve
write performance of concurrent direct I/O writes to multiple
files.
* Refactor and add kunit tests to the extent splitting and
conversion code paths.
Various Bug Fixes
* Fix a panic when the debugging DOUBLE_CHECK macro is defined.
* Avoid using fast commit for rare and complex file system
operations to make fast commit easier to reason about. This can
also avoid some corner cases that could result in file system
inconsistency if there is a crash between the fast commit before a
subsequent full commit.
* Fix memory leaks in error paths
* Fix a false positive reports caused when running stress tests
using mixed huge-page workloads caused by a race between page
migration and bitmap updates.
* Fix a potential recursion into file system reclaim when evicting
an inode when fast commit is enabled.
* Fix a warning caused by a potential double decrement to the dirty
clusters counter when executing FS_IOC_SHUTDOWN when running a
stress test.
* Enable mballoc optimzied scanning regardless whether the inode is
using indirect blocks or extent trees to map blocks.

NFSD 7.0 Release Notes
Neil Brown and Jeff Layton contributed a dynamic thread pool sizing mechanism for NFSD. The sunrpc layer now tracks minimum and maximum thread counts per pool, and NFSD adjusts running thread counts based on workload: idle threads exit after a timeout when the pool exceeds its minimum, and new threads spawn automatically when all threads are busy. Administrators control this behavior via the nfsdctl netlink interface. Rick Macklem, FreeBSD NFS maintainer, generously contributed server- side support for the POSIX ACL extension to NFSv4, as specified in draft-ietf-nfsv4-posix-acls. This extension allows NFSv4 clients to get and set POSIX access and default ACLs using native NFSv4 operations, eliminating the need for sideband protocols. The feature is gated by a Kconfig option since the IETF draft has not yet been ratified. Chuck Lever delivered numerous improvements to the xdrgen tool. Error reporting now covers parsing, AST transformation, and invalid declarations. Generated enum decoders validate incoming values against valid enumerator lists. New features include pass-through line support for embedding C directives in XDR specifications, 16-bit integer types, and program number definitions. Several code generation issues were also addressed. When an administrator revokes NFSv4 state for a filesystem via the unlock_fs interface, ongoing async COPY operations referencing that filesystem are now cancelled, with CB_OFFLOAD callbacks notifying affected clients. The remaining patches in this pull request are clean-ups and minor optimizations. Sincere thanks to all contributors, reviewers, testers, and bug reporters who participated in the v7.0 NFSD development cycle. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEKLLlsBKG3yQ88j7+M2qzM29mf5cFAmmJ8kAACgkQM2qzM29m f5ejCQ//RdoWNgN1VZdNoUrh1tm1Fhi1YN/RJS26G25OxgTBc3/qtGxrpW+ZAW6+ mIAJ2bT/l66741drki4/x6WJU4OMI/4mJxrLd0WCb1POaeRQWnL1MdzNY+IP/QZv 3DgcTv1T6FKE7pFmAqW0nFPCgaK+vlR+fo4uJognbB6+hZB3HlrLkfeZOWMAmchC y3U6nzrtP+IljAtdzKZ120E+LHp0PtTbJwPCPSt3/FR/dkA0DcjnOS9jybIYlJOu 0ByX24BcrW/c3rJUdL8lL4G7gsPWjdARqczFiN8sufI9Q3zlHOxtYdUT7BNjd+04 jcSKLlAXwcbNcK2f54B/QFKmNxllvoHLB3wo2hfEPig4LQELuxcUHYxmmD4vNKen lp6zmaLq3PiRGlew6eLRFxRxbdLds+9l0xjXV+J+rtQmjppXdXUoVNMm+D+tD6bF T5TUq4WNCGJIrpkR7pdF7uMD51s8fphvaDxOCjhSi3WHAtZAhOR8HFUU97qddM34 KqF6Gph3tN/C4oNb8kKvzxBRpRhHIzKHZbreiu5fZr9pPe9IRBHnn/Dg4p/yYQcw K3/y1EnKrIlprfbFFkY1LzNFpf309uoZTVzwBcMfSJVsFgUqWD7KHJ/rmCJQ/pS6 k0+YLRoUmtUHDYk2QNlstlt7r6FwA0d2GjT8n7viGoNQ3PA7rJQ= =hqla -----END PGP SIGNATURE----- Merge tag 'nfsd-7.0' of git://git.kernel.org/pub/scm/linux/kernel/git/cel/linux Pull nfsd updates from Chuck Lever: "Neil Brown and Jeff Layton contributed a dynamic thread pool sizing mechanism for NFSD.

Networking changes for 7.0
Core & protocols
----------------
- A significant effort all around the stack to guide the compiler to
make the right choice when inlining code, to avoid unneeded calls for
small helper and stack canary overhead in the fast-path. This
generates better and faster code with very small or no text size
increases, as in many cases the call generated more code than the
actual inlined helper.
- Extend AccECN implementation so that is now functionally complete,
also allow the user-space enabling it on a per network namespace
basis.
- Add support for memory providers with large (above 4K) rx buffer.
Paired with hw-gro, larger rx buffer sizes reduce the number of
buffers traversing the stack, dincreasing single stream CPU usage by
up to ~30%.
- Do not add HBH header to Big TCP GSO packets. This simplifies the RX
path, the TX path and the NIC drivers, and is possible because
user-space taps can now interpret correctly such packets without the
HBH hint.
- Allow IPv6 routes to be configured with a gateway address that is
resolved out of a different interface than the one specified, aligning
IPv6 to IPv4 behavior.
- Multi-queue aware sch_cake. This makes it possible to scale the rate
shaper of sch_cake across multiple CPUs, while still enforcing a
single global rate on the interface.
- Add support for the nbcon (new buffer console) infrastructure to
netconsole, enabling lock-free, priority-based console operations that
are safer in crash scenarios.
- Improve the TCP ipv6 output path to cache the flow information, saving
cpu cycles, reducing cache line misses and stack use.
- Improve netfilter packet tracker to resolve clashes for most protocols,
avoiding unneeded drops on rare occasions.
- Add IP6IP6 tunneling acceleration to the flowtable infrastructure.
- Reduce tcp socket size by one cache line.
- Notify neighbour changes atomically, avoiding inconsistencies between
the notification sequence and the actual states sequence.
- Add vsock namespace support, allowing complete isolation of vsocks
across different network namespaces.
- Improve xsk generic performances with cache-alignment-oriented
optimizations.
- Support netconsole automatic target recovery, allowing netconsole
to reestablish targets when underlying low-level interface comes back
online.
Driver API
----------
- Support for switching the working mode (automatic vs manual) of a DPLL
device via netlink.
- Introduce PHY ports representation to expose multiple front-facing
media ports over a single MAC.
- Introduce "rx-polarity" and "tx-polarity" device tree properties, to
generalize polarity inversion requirements for differential signaling.
- Add helper to create, prepare and enable managed clocks.
Device drivers
--------------
- Add Huawei hinic3 PF etherner driver.
- Add DWMAC glue driver for Motorcomm YT6801 PCIe ethernet controller.
- Add ethernet driver for MaxLinear MxL862xx switches
- Remove parallel-port Ethernet driver.
- Convert existing driver timestamp configuration reporting to
hwtstamp_get and remove legacy ioctl().
- Convert existing drivers to .get_rx_ring_count(), simplifing the RX
ring count retrieval. Also remove the legacy fallback path.
- Ethernet high-speed NICs:
- Broadcom (bnxt, bng):
- bnxt: add FW interface update to support FEC stats histogram and
NVRAM defragmentation
- bng: add TSO and H/W GRO support
- nVidia/Mellanox (mlx5):
- improve latency of channel restart operations, reducing the used
H/W resources
- add TSO support for UDP over GRE over VLAN
- add flow counters support for hardware steering (HWS) rules
- use a static memory area to store headers for H/W GRO, leading to
12% RX tput improvement
- Intel (100G, ice, idpf):
- ice: reorganizes layout of Tx and Rx rings for cacheline
locality and utilizes __cacheline_group* macros on the new layouts
- ice: introduces Synchronous Ethernet (SyncE) support
- Meta (fbnic):
- adds debugfs for firmware mailbox and tx/rx rings vectors
- Ethernet virtual:
- geneve: introduce GRO/GSO support for double UDP encapsulation
- Ethernet NICs consumer, and embedded:
- Synopsys (stmmac):
- some code refactoring and cleanups
- RealTek (r8169):
- add support for RTL8127ATF (10G Fiber SFP)
- add dash and LTR support
- Airoha:
- AN8811HB 2.5 Gbps phy support
- Freescale (fec):

Merge tag 'net-next-7.0' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next
Pull networking updates from Paolo Abeni:
"Core & protocols:
- A significant effort all around the stack to guide the compiler to
make the right choice when inlining code, to avoid unneeded calls
for small helper and stack canary overhead in the fast-path.
This generates better and faster code with very small or no text
size increases, as in many cases the call generated more code than
the actual inlined helper.
- Extend AccECN implementation so that is now functionally complete,
also allow the user-space enabling it on a per network namespace
basis.
- Add support for memory providers with large (above 4K) rx buffer.
Paired with hw-gro, larger rx buffer sizes reduce the number of
buffers traversing the stack, dincreasing single stream CPU usage
by up to ~30%.
- Do not add HBH header to Big TCP GSO packets. This simplifies the
RX path, the TX path and the NIC drivers, and is possible because
user-space taps can now interpret correctly such packets without
the HBH hint.
- Allow IPv6 routes to be configured with a gateway address that is
resolved out of a different interface than the one specified,
aligning IPv6 to IPv4 behavior.
- Multi-queue aware sch_cake. This makes it possible to scale the
rate shaper of sch_cake across multiple CPUs, while still enforcing
a single global rate on the interface.
- Add support for the nbcon (new buffer console) infrastructure to
netconsole, enabling lock-free, priority-based console operations
that are safer in crash scenarios.
- Improve the TCP ipv6 output path to cache the flow information,
saving cpu cycles, reducing cache line misses and stack use.
- Improve netfilter packet tracker to resolve clashes for most
protocols, avoiding unneeded drops on rare occasions.
- Add IP6IP6 tunneling acceleration to the flowtable infrastructure.
- Reduce tcp socket size by one cache line.
- Notify neighbour changes atomically, avoiding inconsistencies
between the notification sequence and the actual states sequence.
- Add vsock namespace support, allowing complete isolation of vsocks
across different network namespaces.
- Improve xsk generic performances with cache-alignment-oriented
optimizations.
- Support netconsole automatic target recovery, allowing netconsole
to reestablish targets when underlying low-level interface comes
back online.
Driver API:
- Support for switching the working mode (automatic vs manual) of a
DPLL device via netlink.
- Introduce PHY ports representation to expose multiple front-facing
media ports over a single MAC.
- Introduce "rx-polarity" and "tx-polarity" device tree properties,
to generalize polarity inversion requirements for differential
signaling.
- Add helper to create, prepare and enable managed clocks.
Device drivers:
- Add Huawei hinic3 PF etherner driver.
- Add DWMAC glue driver for Motorcomm YT6801 PCIe ethernet
controller.
- Add ethernet driver for MaxLinear MxL862xx switches
- Remove parallel-port Ethernet driver.
- Convert existing driver timestamp configuration reporting to
hwtstamp_get and remove legacy ioctl().
- Convert existing drivers to .get_rx_ring_count(), simplifing the RX
ring count retrieval. Also remove the legacy fallback path.
- Ethernet high-speed NICs:
- Broadcom (bnxt, bng):
- bnxt: add FW interface update to support FEC stats histogram
and NVRAM defragmentation
- bng: add TSO and H/W GRO support
- nVidia/Mellanox (mlx5):
- improve latency of channel restart operations, reducing the
used H/W resources
- add TSO support for UDP over GRE over VLAN
- add flow counters support for hardware steering (HWS) rules
- use a static memory area to store headers for H/W GRO,
leading to 12% RX tput improvement
- Intel (100G, ice, idpf):
- ice: reorganizes layout of Tx and Rx rings for cacheline
locality and utilizes __cacheline_group* macros on the new
layouts
- ice: introduces Synchronous Ethernet (SyncE) support
- Meta (fbnic):
- adds debugfs for firmware mailbox and tx/rx rings vectors
- Ethernet virtual:
- geneve: introduce GRO/GSO support for double UDP encapsulation
- Ethernet NICs consumer, and embedded:
- Synopsys (stmmac):
- some code refactoring and cleanups
- RealTek (r8169):
- add support for RTL8127ATF (10G Fiber SFP)
- add dash and LTR support
- Airoha:
- AN8811HB 2.5 Gbps phy support
- Freescale (fec):
- add XDP zero-copy support

Driver core changes for 7.0-rc1
- Bus:
- Ensure bus->match() is consistently called with the device lock held
- Improve type safety of bus_find_device_by_acpi_dev()
- Devtmpfs:
- Parse 'devtmpfs.mount=' boot parameter with kstrtoint() instead of
simple_strtoul()
- Avoid sparse warning by making devtmpfs_context_ops static
- IOMMU:
- Do not register the qcom_smmu_tbu_driver in arm_smmu_device_probe()
- MAINTAINERS:
- Add the new driver-core mailing list (driver-core@lists.linux.dev)
to all relevant entries
- Add missing tree location for "FIRMWARE LOADER (request_firmware)"
- Add driver-model documentation to the "DRIVER CORE" entry
- Add missing driver-core maintainers to the "AUXILIARY BUS" entry
- Misc:
- Change return type of attribute_container_register() to void; it has
always been infallible
- Do not export sysfs_change_owner(), sysfs_file_change_owner() and
device_change_owner()
- Move devres_for_each_res() from the public devres header to
drivers/base/base.h
- Do not use a static struct device for the faux bus; allocate it
dynamically
- Revocable:
- Patches for the revocable synchronization primitive have been
scheduled for v7.0-rc1, but have been reverted as they need some
more refinement
- Rust:
- Device:
- Support dev_printk on all device types, not just the core Device
struct; remove now-redundant .as_ref() calls in dev_* print calls
- Devres:
- Introduce an internal reference count in Devres<T> to avoid a
deadlock condition in case of (indirect) nesting
- DMA:
- Allow drivers to tune the maximum DMA segment size via
dma_set_max_seg_size()

- Introduce the concept of generic I/O backends to handle different
kinds of device shared memory through a common interface.
This enables higher-level concepts such as register abstractions,
I/O slices, and field projections to be built generically on top.
In a first step, introduce the Io, IoCapable<T>, and IoKnownSize
trait hierarchy for sharing a common interface supporting offset
validation and bound-checking logic between I/O backends.
- Refactor MMIO to use the common I/O backend infrastructure
- Misc:
- Add __rust_helper annotations to C helpers for inlining into Rust
code
- Use "kernel vertical" style for imports
- Replace kernel::c_str! with C string literals
- Update ARef imports to use sync::aref
- Use pin_init::zeroed() for struct auxiliary_device_id and debugfs
file_operations initialization

- Various minor comment and documentation fixes
- PCI:
- Implement PCI configuration space accessors using the common I/O

Pull PCI updates from Bjorn Helgaas:
"Enumeration:
- Don't try to enable Extended Tags on VFs since that bit is Reserved
and causes misleading log messages (Håkon Bugge)
- Initialize Endpoint Read Completion Boundary to match Root Port,
regardless of ACPI _HPX (Håkon Bugge)
- Apply _HPX PCIe Setting Record only to AER configuration, and only
when OS owns PCIe hotplug but not AER, to avoid clobbering Extended
Tag and Relaxed Ordering settings (Håkon Bugge)
Resource management:
- Move CardBus code to setup-cardbus.c and only build it when
CONFIG_CARDBUS is set (Ilpo Järvinen)
- Fix bridge window alignment with optional resources, where
additional alignment requirement was previously lost (Ilpo
Järvinen)
- Stop over-estimating bridge window size since they are now assigned
without any gaps between them (Ilpo Järvinen)
- Increase resource MAX_IORES_LEVEL to avoid /proc/iomem flattening
for nested bridges and endpoints (Ilpo Järvinen)
- Add pbus_mem_size_optional() to handle sizes of optional resources
(SR-IOV VF BARs, expansion ROMs, bridge windows) (Ilpo Järvinen)
- Don't claim disabled bridge windows to avoid spurious claim
failures (Ilpo Järvinen)
Driver binding:
- Fix device reference leak in pcie_port_remove_service() (Uwe
Kleine-König)
- Move pcie_port_bus_match() and pcie_port_bus_type to PCIe-specific
portdrv.c (Uwe Kleine-König)
- Convert portdrv to use pcie_port_bus_type.probe() and .remove()
callbacks so .probe() and .remove() can eventually be removed from
struct device_driver (Uwe Kleine-König)
Error handling:
- Clear stale errors on reporting agents upon probe so they don't
look like recent errors (Lukas Wunner)
- Add generic RAS tracepoint for hotplug events (Shuai Xue)
- Add RAS tracepoint for link speed changes (Shuai Xue)
Power management:
- Avoid redundant delay on transition from D3hot to D3cold if the
device was already in D3hot (Brian Norris)
- Prevent runtime suspend until devices are fully initialized to
avoid saving incompletely configured device state (Brian Norris)
Power control:
- Add power_on/off callbacks with generic signature to pwrseq,
tc9563, and slot drivers so they can be used by pwrctrl core
(Manivannan Sadhasivam)
- Add PCIe M.2 connector support to the slot pwrctrl driver
(Manivannan Sadhasivam)
- Switch to pwrctrl interfaces to create, destroy, and power on/off
devices, calling them from host controller drivers instead of the
PCI core (Manivannan Sadhasivam)
- Drop qcom .assert_perst() callbacks since this is now done by the
controller driver instead of the pwrctrl driver (Manivannan
Sadhasivam)
Virtualization:
- Remove an incorrect unlock in pci_slot_trylock() error handling
(Jinhui Guo)
- Lock the bridge device for slot reset (Keith Busch)
- Enable ACS after IOMMU configuration on OF platforms so ACS is
enabled an all devices; previously the first device enumerated
(typically a Root Port) didn't have ACS enabled (Manivannan
Sadhasivam)
- Disable ACS Source Validation for IDT 0x80b5 and 0x8090 switches to
work around hardware erratum; previously ACS SV was only
temporarily disabled, which worked for enumeration but not after
reset (Manivannan Sadhasivam)
Peer-to-peer DMA:
- Release per-CPU pgmap ref when vm_insert_page() fails to avoid hang
when removing the PCI device (Hou Tao)
- Remove incorrect p2pmem_alloc_mmap() warning about page refcount
(Hou Tao)
Endpoint framework:
- Add configfs sub-groups synchronously to avoid NULL pointer
dereference when racing with removal (Liu Song)
- Fix swapped parameters in pci_{primary/secondary}_epc_epf_unlink()
functions (Manikanta Maddireddy)
ASPEED PCIe controller driver:
- Add ASPEED Root Complex DT binding and driver (Jacky Chou)
Freescale i.MX6 PCIe controller driver:
- Add DT binding and driver support for an optional external refclock
in addition to the refclock from the internal PLL (Richard Zhu)
- Fix CLKREQ# control so host asserts it during enumeration and
Endpoints can use it afterwards to exit the L1.2 link state
(Richard Zhu)
NVIDIA Tegra PCIe controller driver:
- Export irq_domain_free_irqs() to allow PCI/MSI drivers that tear
down MSI domains to be built as modules (Aaron Kling)
- Allow pci-tegra to be built as a module (Aaron Kling)
NVIDIA Tegra194 PCIe controller driver:
- Relax Kconfig so tegra194 can be built for platforms beyond
Tegra194 (Vidya Sagar)
Qualcomm PCIe controller driver:
- Merge SC8180x DT binding into SM8150 (Krzysztof Kozlowski)
- Move SDX55, SDM845, QCS404, IPQ5018, IPQ6018, IPQ8074 Gen3,
IPQ8074, IPQ4019, IPQ9574, APQ8064, MSM8996, APQ8084 to dedicated
schema (Krzysztof Kozlowski)
- Add DT binding and driver support for SA8255p Endpoint being
configured by firmware (Mrinmay Sarkar)
- Parse PERST# from all PCIe bridge nodes for future platforms that
will have PERST# in Switch Downstream Ports as well as in Root
Ports (Manivannan Sadhasivam)
Renesas RZ/G3S PCIe controller driver:
- Use pci_generic_config_write() since the writability provided by
the custom wrapper is unnecessary (Claudiu Beznea)
SOPHGO PCIe controller driver:
- Disable ASPM L0s and L1 on Sophgo 2044 PCIe Root Ports (Inochi
Amaoto)
Synopsys DesignWare PCIe controller driver:
- Extend PCI_FIND_NEXT_CAP() and PCI_FIND_NEXT_EXT_CAP() to return a
pointer to the preceding Capability, to allow removal of
Capabilities that are advertised but not fully implemented (Qiang
Yu)
- Remove MSI and MSI-X Capabilities in platforms that can't support
them, so the PCI core automatically falls back to INTx (Qiang Yu)
- Add ASPM L1.1 and L1.2 Substates context to debugfs ltssm_status
for drivers that support this (Shawn Lin)
- Skip PME_Turn_Off broadcast and L2/L3 transition during suspend if
link is not up to avoid an unnecessary timeout (Manivannan
Sadhasivam)
- Revert dw-rockchip, qcom, and DWC core changes that used link-up
IRQs to trigger enumeration instead of waiting for link to be up
because the PCI core doesn't allocate bus number space for
hierarchies that might be attached (Niklas Cassel)
- Make endpoint iATU entry for MSI permanent instead of programming
it dynamically, which is slow and racy with respect to other
concurrent traffic, e.g., eDMA (Koichiro Den)
- Use iMSI-RX MSI target address when possible to fix endpoints using
32-bit MSI (Shawn Lin)
- Allow DWC host controller driver probe to continue if device is not
found or found but inactive; only fail when there's an error with
the link (Manivannan Sadhasivam)
- For controllers like NXP i.MX6QP and i.MX7D, where LTSSM registers
are not accessible after PME_Turn_Off, simply wait 10ms instead of
polling for L2/L3 Ready (Richard Zhu)
- Use multiple iATU entries to map large bridge windows and DMA
ranges when necessary instead of failing (Samuel Holland)
- Add EPC dynamic_inbound_mapping feature bit for Endpoint
Controllers that can update BAR inbound address translation without
requiring EPF driver to clear/reset the BAR first, and advertise it
for DWC-based Endpoints (Koichiro Den)
- Add EPC subrange_mapping feature bit for Endpoint Controllers that
can map multiple independent inbound regions in a single BAR,
implement subrange mapping, advertise it for DWC-based Endpoints,
and add Endpoint selftests for it (Koichiro Den)
- Make resizable BARs work for Endpoint multi-PF configurations;
previously it only worked for PF 0 (Aksh Garg)
- Fix Endpoint non-PF 0 support for BAR configuration, ATU mappings,
and Address Match Mode (Aksh Garg)
- Set up iATU when ECAM is enabled; previously IO and MEM outbound
windows weren't programmed, and ECAM-related iATU entries weren't
restored after suspend/resume, so config accesses failed (Krishna
Chaitanya Chundru)
Miscellaneous:
- Use system_percpu_wq and WQ_PERCPU to explicitly request per-CPU
work so WQ_UNBOUND can eventually be removed (Marco Crivellari)"

cgroup: Changes for v6.20
- cpuset changes:
- Continue separating v1 and v2 implementations by moving more
v1-specific logic into cpuset-v1.c.
- Improve partition handling. Sibling partitions are no longer
invalidated on cpuset.cpus conflict, cpuset.cpus changes no longer
fail in v2, and effective_xcpus computation is made consistent.
- Fix partition effective CPUs overlap that caused a warning on cpuset
removal when sibling partitions shared CPUs.
- Increase the maximum cgroup subsystem count from 16 to 32 to
accommodate future subsystem additions.
- Misc cleanups and selftest improvements including switching to
css_is_online() helper, removing dead code and stale documentation
references, using lockdep_assert_cpuset_lock_held() consistently,
and adding polling helpers for asynchronously updated cgroup
statistics.

Merge tag 'cgroup-for-6.20' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup
Pull cgroup updates from Tejun Heo:
- cpuset changes:
- Continue separating v1 and v2 implementations by moving more
v1-specific logic into cpuset-v1.c
- Improve partition handling. Sibling partitions are no longer
invalidated on cpuset.cpus conflict, cpuset.cpus changes no longer
fail in v2, and effective_xcpus computation is made consistent
- Fix partition effective CPUs overlap that caused a warning on
cpuset removal when sibling partitions shared CPUs
- Increase the maximum cgroup subsystem count from 16 to 32 to
accommodate future subsystem additions
- Misc cleanups and selftest improvements including switching to
css_is_online() helper, removing dead code and stale documentation
references, using lockdep_assert_cpuset_lock_held() consistently, and
adding polling helpers for asynchronously updated cgroup statistics

sound updates for 7.0-rc1
It's been relatively calm for a new era; majority of changes are for
ASoC, mostly device-specific changes, while there are a bit of
cleanups in core stuff. A few SPI API and regmap updates are included
to be used by sound drivers, too.
Core:
- A few trivial cleanups about __free() and runtime PM macros
- Convert to new snd_seq_bus binding
ASoC:
- Generic SDCA support for reporting jack events
- Continuing platform support, cleanup and feature improvements for
AMD, Intel, Qualcomm and SOF code
- Platform description improvements for the Cirrus drivers
- Support for NXP i.MX952, Realtek RT1320 and RT5575, and Sophogo
CV1800B
HD- and USB-audio:
- Many quirks as usual

Pull sound updates from Takashi Iwai:
"It's been relatively calm for a new era; majority of changes are for
ASoC, mostly device-specific changes, while there are a bit of
cleanups in core stuff. A few SPI API and regmap updates are included
to be used by sound drivers, too.
Core:
- A few trivial cleanups about __free() and runtime PM macros
- Convert to new snd_seq_bus binding
ASoC:
- Generic SDCA support for reporting jack events
- Continuing platform support, cleanup and feature improvements for
AMD, Intel, Qualcomm and SOF code
- Platform description improvements for the Cirrus drivers
- Support for NXP i.MX952, Realtek RT1320 and RT5575, and Sophogo
CV1800B

firewire updates for v7.0
This update includes the following changes.
- Refactor page allocation dedicated to 1394 OHCI IR/IT/AR DMA contexts
Although 1394 OHCI specification does not impose any restriction on
the memory size dedicated to these DMA contexts, 1394 OHCI PCI driver
allocates pages for convenience when mapping them into either kernel
space or userspace VMA. The driver previously used dma_alloc_pages()
for both page allocation and mapping creation, even though this kernel
API is rarely used. Following discussions questioning the page-oriented
kernel API in the DMA layer, the driver has been refactored to avoid
using this API. In addition, the use of private members in the
allocated pages has been removed following long-standing concern.
- Allocate variable-sized buffer for isochronous context header
1394 OHCI PCI driver previously allocated a single page for isochronous
context header. As a result, the buffer size for the header was fixed
to PAGE_SIZE, which imposed a limitation on IEC 61883-1/6 packet
streaming engine. Consequently, the ALSA PCM devices provided by
drivers for audio and music units in IEEE 1394 bus were constrained in
the maximum size of buffer period (64 ms in most cases). This limitation
is resolved by dynamically allocating the header buffer with an
arbitrary size.

spi: Updates for v7.0
The highlight here is that David Lechner has added support for multi-lane
SPI devices. Unlike the existing dual/quad SPI support this is for
devices (typically ADCs/DACs) which support multiple independent data
streams over multiple data lanes, instead of sending one data stream N
times as fast they simultaneously transfer N different data streams.
This is very similar to the case where multiple devices are grouped
together but in this case it's a single device in a way that's visible
to software.
Otherwise there's been quite a bit of work on existing drivers, both
cleanup and feature improvement, and a reasonable collection of new
drivers.
- Support for multi-lane SPI devices.
- Preparatory work for some memory mapped flash improvements that will
happen in the MTD subsystem.
- Several conversions to fwnode APIs.
- A bunch of cleanup and hardening work on the ST drivers.
- Support for DMA mode on Renesas RZV2H and i.MX target mode.
- Support for ATCSPI200, AXIADO AX300, NXP XPI and Renesas RZ/N1.

regulator: Updates for v7.0
There's a bunch of new drivers here, plus a lot of hardening for the
supply resolution code which allow us to support systems where we have
two PMICs each of which has regulators supplied by the other. This did
work a long time ago but got broken as part of improved integration with
the device model, it's fairly rare so nobody noticed.
- Improvements for supply handling from André Draszik to allow systems
with two PMICs with supply/consumer relationships in both
directions to instantiate.
- New drivers for Maxim MAX776750, Realtek RT8902, Samsung S2MPG11,
Texas Instuments TPS65185.
This have also pulls in some MFD updates which are build dependencies
for the Samsung S2MPG11 support.

This is useful for devices where there are large ranges of registers with the same or generateable values, it allows us to have a small amount of code instead of a larger amount of default data. -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAmmJ69gACgkQJNaLcl1U h9BWFAf+ICxKNiAtJWfApq09F2WNdsI8qtc9PQuf6wi1cGLTE/mc+nC7LAljP/YQ VqTJ67HEtKNlrmREdULKrn9rNhpZ24vPXr7VozScisR682muXqtoKhhiHfHfTKCt 47ptg4H3gppvsfXcPjxklsj3UCpv36nKZB9lKb18fTvDIwriwAU5e9P9JPtJ9fWc IQo2KvZ4ENnEiEX6RN9jBukSvS/a97+UtG+i8c0qBaqLm9jGOz7fWfxGsSKtflIu /JIqjsbGkA6Jo2Hz4rrIGi+anRPDNp0RFW6lSXrEWc2QU1aZgCXWEtBElxCbSYvc JDeU1pnKKAlpItXj91IgcV7rv4LJjQ== =sD3p -----END PGP SIGNATURE----- Merge tag 'regmap-v6.20' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap Pull regmap updates from Mark Brown: "The main change here is the implementation of a mechanism for generating register defaults via a callback rather than with a table in the driver.

bnge/bng_re: Add a new HSI
The HSI is shared between the firmware and the driver and is automatically generated. Add a new HSI for the BNGE driver. The current HSI refers to BNXT, which will become incompatible with ThorUltra devices as the BNGE driver adds more features. The BNGE driver will not use the HSI located in the bnxt folder. Also, add an HSI for ThorUltra RoCE driver.

soc: devicetree updates for 7.0
There are a handful of new SoCs this time, all of these are
more or less related to chips in a wider family:
- SpacemiT Key Stone K3 is an 8-core risc-v chip, and the first
widely available RVA23 implementation. Note that this is
entirely unrelated with the similarly named Texas Instruments
K3 chip family that follwed the TI Keystone2 SoC.
- The Realtek Kent family of SoCs contains three chip models
rtd1501s, rtd1861b and rtd1920s, and is related to their earlier
Set-top-box and NAS products such as rtd1619, but is built
on newer Arm Cortex-A78 cores.
- The Qualcomm Milos family includes the Snapdragon 7s Gen 3
(SM7635) mobile phone SoC built around Armv9 Kryo cores of the Arm
Cortex-A720 generation. This one is used in the Fairphone Gen 6
- Qualcomm Kaanapali is a new SoC based around eight high
performance Oryon CPU cores
- NXP i.MX8QP and i.MX952 are both feature reduced versions of
chips we already support, i.e. the i.MX8QM and i.MX952, with
fewer CPU cores and I/O interfaces.
As part of a cleanup, a number of SoC specific devicetree files got
removed because they did not have a single board using the .dtsi files
and they were never compile tested as a result: Samsung s3c6400,
ST spear320s, ST stm32mp21xc/stm32mp23xc/stm32mp25xc, Renesas
r8a779m0/r8a779m2/r8a779m4/r8a779m6/r8a779m7/r8a779m8/r8a779mb/
r9a07g044c1/r9a07g044l1/r9a07g054l1/r9a09g047e37, and TI am3703/am3715.
All of these could be restored easily if a new board gets merged.
Broadcom/Cavium/Marvell ThunderX2 gets removed along with its only
machine, as all remaining users are assumed to be using ACPI
based firmware.
A relatively small number of 43 boards get added this time, and
almost all of them for arm64. Aside from the reference boards for
the newly added SoCs, this includes:
- Three server boards use 32-bit ASpeed BMCs
- One more reference board for 32-bit Microchip LAN9668
- 64-bit Arm single-board computers based on Amlogic s905y4,
CIX sky1, NXP ls1028a/imx8mn/imx8mp/imx91/imx93/imx95,
Qualcomm qcs6490/qrb2210 and Rockchip rk3568/rk3588s
- Carrier board for SOMs using Intel agilex5, Marvell Armada 7020,
NXP iMX8QP, Mediatek mt8370/mt8390 and rockchip rk3588
- Two mobile phones using Snapdragon 845
- A gaming device and a NAS box, both based on Rockchips rk356x
On top of the newly added boards and SoCs, there is a lot of
background activity going into cleanups, in particular towards
getting a warning-free dtc build, and the usual work on adding
support for more hardware on the previously added machines.

soc: driver updates for 7.0
There are are a number of to firmware drivers, in particular the TEE
subsystem:
- a bus callback for TEE firmware that device drivers can register to
- sysfs support for tee firmware information
- minor updates to platform specific TEE drivers for AMD, NXP, Qualcomm
and the generic optee driver
- ARM SCMI firmware refactoring to improve the protocol discover
among other fixes and cleanups
- ARM FF-A firmware interoperability improvements
The reset controller and memory controller subsystems gain support for
additional hardware platforms from Mediatek, Renesas, NXP, Canaan and
SpacemiT.
Most of the other changes are for random drivers/soc code. Among
a number of cleanups and newly added hardware support, including:
- Mediatek MT8196 DVFS power management and mailbox support
- Qualcomm SCM firmware and MDT loader refactoring, as part of
the new Glymur platform support.

asm-generic header updates for 7.0
A series from Thomas Weißschuh cleans up the UAPI header files to no longer contain any references to Kconfig symbols, as these make no sense in userspace.

From Qingfang Deng. 5) Recent net-next update extended existing test for ip6ip6 tunnels, add the required /config entry. Test still passed by accident because the previous tests network setup gets re-used, so also update the test so it will fail in case the ip6ip6 tunnel interface cannot be added. 6) Fix 'nft get element mytable myset { 1.2.3.4 }' on big endian platforms, this was broken since code was added in v5.1. 7) Fix nf_tables counter reset support on 32bit platforms, where counter reset may cause huge values to appear due to wraparound. Broken since reset feature was added in v6.11. From Anders Grahn. 8-11) update nf_tables rbtree set type to detect partial operlaps.

xfrm: reduce struct sec_path size
The mentioned struct has an hole and uses unnecessary wide type to
store MAC length and indexes of very small arrays.
It's also embedded into the skb_extensions, and the latter, due
to recent CAN changes, may exceeds the 192 bytes mark (3 cachelines
on x86_64 arch) on some reasonable configurations.
Reordering and the sec_path fields, shrinking xfrm_offload.orig_mac_len
to 16 bits and xfrm_offload.{len,olen,verified_cnt} to u8, we can save
16 bytes and keep skb_extensions size under control.
Before:
struct sec_path {
int len;
int olen;
int verified_cnt;
/* XXX 4 bytes hole, try to pack */$
struct xfrm_state * xvec[6];
struct xfrm_offload ovec[1];
/* size: 88, cachelines: 2, members: 5 */
/* sum members: 84, holes: 1, sum holes: 4 */
/* last cacheline: 24 bytes */
};
After:
struct sec_path {
struct xfrm_state * xvec[6];
struct xfrm_offload ovec[1];
/* typedef u8 -> __u8 */ unsigned char len;
/* typedef u8 -> __u8 */ unsigned char olen;
/* typedef u8 -> __u8 */ unsigned char verified_cnt;
/* size: 72, cachelines: 2, members: 5 */
/* padding: 1 */
/* last cacheline: 8 bytes */
};

printk: Add execution context (task name/CPU) to printk_info
Extend struct printk_info to include the task name, pid, and CPU number where printk messages originate. This information is captured at vprintk_store() time and propagated through printk_message to nbcon_write_context, making it available to nbcon console drivers. This is useful for consoles like netconsole that want to include execution context in their output, allowing correlation of messages with specific tasks and CPUs regardless of where the console driver actually runs. The feature is controlled by CONFIG_PRINTK_EXECUTION_CTX, which is automatically selected by CONFIG_NETCONSOLE_DYNAMIC. When disabled, the helper functions compile to no-ops with no overhead.

Updates for the VDSO subsystem:
- Provide the missing 64-bit variant of clock_getres()
This allows the extension of CONFIG_COMPAT_32BIT_TIME to the vDSO and
finally the removal of 32-bit time types from the kernel and UAPI.
- Remove the useless and broken getcpu_cache from the VDSO
The intention was to provide a trivial way to retrieve the CPU number from
the VDSO, but as the VDSO data is per process there is no way to make it
work.
- Switch get/put_unaligned() from packed struct to memcpy()
The packed struct violates strict aliasing rules which requires to pass
-fno-strict-aliasing to the compiler. As this are scalar values
__builtin_memcpy() turns them into simple loads and stores
- Use __typeof_unqual__() for __unqual_scalar_typeof()
The get/put_unaligned() changes triggered a new sparse warning when __beNN
types are used with get/put_unaligned() as sparse builds add a special
'bitwise' attribute to them which prevents sparse to evaluate the Generic
in __unqual_scalar_typeof().
Newer sparse versions support __typeof_unqual__() which avoids the problem,
but requires a recent sparse install. So this adds a sanity check to sparse
builds, which validates that sparse is available and capable of handling it.
- Force inline __cvdso_clock_getres_common()
Compilers sometimes un-inline agressively, which results in function call
overhead and problems with automatic stack variable initialization.
Interestingly enough the force inlining results in smaller code than the
un-inlined variant produced by GCC when optimizing for size.

Updates for the [PCI] MSI subsystem:
- Add interrupt redirection infrastructure
Some PCI controllers use a single demultiplexing interrupt for the MSI
interrupts of subordinate devices.
This prevents setting the interrupt affinity of device interrupts, which
causes device interrupts to be delivered to a single CPU. That obviously is
counterproductive for multi-queue devices and interrupt balancing.
To work around this limitation the new infrastructure installs a dummy
irq_set_affinity() callback which captures the affinity mask and picks a
redirection target CPU out of the mask.
When the PCI controller demultiplexes the interrupts it invokes a new
handling function in the core, which either runs the interrupt handler in
the context of the target CPU or delegates it to irq_work on the target CPU.
- Utilize the interrupt redirection mechanism in the PCI DWC host controller
driver.
This allows affinity control for the subordinate device MSI interrupts
instead of being randomly executed on the CPU which runs the demultiplex
handler.
- Replace the binary 64-bit MSI flag with a DMA mask
Some PCI devices have PCI_MSI_FLAGS_64BIT in the MSI capability, but
implement less than 64 address bits. This breaks on platforms where such a
device is assigned an MSI address higher than what's supported.
With the binary 64-bit flag there is no other choice than disabling 64-bit
MSI support which leaves the device disfunctional.
By using a DMA mask the address limit of a device can be described
correctly which provides support for the above scenario.
- Make use of the DMA mask based address limit in the hda/intel and radeon
drivers to enable them on affected platforms.
- The usual small cleanups and improvements
