NFSD 6.15 Release Notes
Neil Brown contributed more scalability improvements to NFSD's open file cache, and Jeff Layton contributed a menagerie of repairs to NFSD's NFSv4 callback / backchannel implementation. Mike Snitzer contributed a change to NFS re-export support that disables support for file locking on a re-exported NFSv4 mount. This is because NFSv4 state recovery is currently difficult if not impossible for re-exported NFS mounts. The change aims to prevent data integrity exposures after the re-export server crashes. Work continues on the evolving NFSD netlink administrative API. Many thanks to the contributors, reviewers, testers, and bug reporters who participated during the v6.15 development cycle. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEKLLlsBKG3yQ88j7+M2qzM29mf5cFAmfmpMIACgkQM2qzM29m f5f6DA/+P0YqoRg3Zk/4oWwXZWbfEOMhWFltT+D1PE2QjUfOZpiwUSFQfsfYgXO6 OFu0iDQ4g8BxBeP6Umv61qy7Cv6n4fVzIHqzymXQvymh9JzoQiXlE9/fA8nAHuiH u7kkNPRi7faBz1sMg/WpN9CHctg7STPOhhG/JrZcSFZnh87mU1i4i4bZBNz8tVnK ZWf483OUuSmJY2/bUTkwvr4GbceTKBlLWFFjiRhfAKvJBWvu4myfC0DI5QzxmsgI MJ62do7AFJP1ww2Ih9LLi2kFIt/yyInSVAgyts1CPhlJ4BfPnTSOw/i2+CuF3D/M bZYEAOjH3AqjBZmq58sIQezpD5f9/TOrTSwYwS31zl/THYE413WiW80/MDoWqo0y 9cSNkD3nJlPVLLCfF58vXLoe7wpLoN/ZbTdxoozzUWEFR5A4Jz3XP8F/Cws0cjem uWWAQMItiQpg1+RYJYfu4dg5+iN6dbgYbvzlr7buISwFNXi3Zo99MkJ4wHj9TJbL Tpjth1rWGPwwSOMT6ojKiYMq1oUzx5PuAm9Saq9oIzQAbBySmxHF/LSDz3wEuBoO MK1jzKroEmMk3fJOOAajSDLOdAbL3vfj6H/xi2IHvKnaz9yHCZNu2YGV05BBMprd hWePf69AO5Ky5Q9KuGClEtwvJ9ZR5pb4DO2dqaYu8ximu3O4vPo= =e2E2 -----END PGP SIGNATURE----- Merge tag 'nfsd-6.15' of git://git.kernel.org/pub/scm/linux/kernel/git/cel/linux Pull nfsd updates from Chuck Lever: "Neil Brown contributed more scalability improvements to NFSD's open file cache, and Jeff Layton contributed a menagerie of repairs to NFSD's NFSv4 callback / backchannel implementation.

ring-buffer updates for v6.15
- Restructure the persistent memory to have a "scratch" area Instead of hard coding the KASLR offset in the persistent memory by the ring buffer, push that work up to the callers of the persistent memory as they are the ones that need this information. The offsets and such is not important to the ring buffer logic and it should not be part of that. A scratch pad is now created when the caller allocates a ring buffer from persistent memory by stating how much memory it needs to save. - Allow where modules are loaded to be saved in the new scratch pad Save the addresses of modules when they are loaded into the persistent memory scratch pad. - A new module_for_each_mod() helper function was created With the acknowledgement of the module maintainers a new module helper function was created to iterate over all the currently loaded modules. This has a callback to be called for each module. This is needed for when tracing is started in the persistent buffer and the currently loaded modules need to be saved in the scratch area. - Expose the last boot information where the kernel and modules were loaded The last_boot_info file is updated to print out the addresses of where the kernel "_text" location was loaded from a previous boot, as well as where the modules are loaded. If the buffer is recording the current boot, it only prints "# Current" so that it does not expose the KASLR offset of the currently running kernel. - Allow the persistent ring buffer to be released (freed) To have this in production environments, where the kernel command line can not be changed easily, the ring buffer needs to be freed when it is not going to be used. The memory for the buffer will always be allocated at boot up, but if the system isn't going to enable tracing, the memory needs to be freed. Allow it to be freed and added back to the kernel memory pool. - Allow stack traces to print the function names in the persistent buffer Now that the modules are saved in the persistent ring buffer, if the same modules are loaded, the printing of the function names will examine the saved modules. If the module is found in the scratch area and is also loaded, then it will do the offset shift and use kallsyms to display the function name. If the address is not found, it simply displays the address from the previous boot in hex. -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCZ+cUERQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qrAsAQCFt2nfzxoe3wtF5EqIT1VHp/8bQVjG gBe8B6ouboreogD/dS7yK8MRy24ZAmObGwYG0RbVicd50S7P8Rf7+823ng8= =OJKk -----END PGP SIGNATURE----- Merge tag 'trace-ringbuffer-v6.15-2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull ring-buffer updates from Steven Rostedt: - Restructure the persistent memory to have a "scratch" area Instead of hard coding the KASLR offset in the persistent memory by the ring buffer, push that work up to the callers of the persistent memory as they are the ones that need this information.

Rust changes for v6.15
Toolchain and infrastructure:
- Extract the 'pin-init' API from the 'kernel' crate and make it into
a standalone crate.
In order to do this, the contents are rearranged so that they can
easily be kept in sync with the version maintained out-of-tree that
other projects have started to use too (or plan to, like QEMU).
This will reduce the maintenance burden for Benno, who will now have
his own sub-tree, and will simplify future expected changes like the
move to use 'syn' to simplify the implementation.
- Add '#[test]'-like support based on KUnit.
We already had doctests support based on KUnit, which takes the
examples in our Rust documentation and runs them under KUnit.
Now, we are adding the beginning of the support for "normal" tests,
similar to those the '#[test]' tests in userspace Rust. For instance:
#[kunit_tests(my_suite)]
mod tests {
#[test]
fn my_test() {
assert_eq!(1 + 1, 2);
}
}
Unlike with doctests, the 'assert*!'s do not map to the KUnit
assertion APIs yet.
- Check Rust signatures at compile time for functions called from C by
name.
In particular, introduce a new '#[export]' macro that can be placed
in the Rust function definition. It will ensure that the function
declaration on the C side matches the signature on the Rust function:
#[export]
pub unsafe extern "C" fn my_function(a: u8, b: i32) -> usize {
// ...
}
The macro essentially forces the compiler to compare the types of
the actual Rust function and the 'bindgen'-processed C signature.
These cases are rare so far. In the future, we may consider
introducing another tool, 'cbindgen', to generate C headers
automatically. Even then, having these functions explicitly marked
may be a good idea anyway.
- Enable the 'raw_ref_op' Rust feature: it is already stable, and
allows us to use the new '&raw' syntax, avoiding a couple macros.
After everyone has migrated, we will disallow the macros.
- Pass the correct target to 'bindgen' on Usermode Linux.
- Fix 'rusttest' build in macOS.
'kernel' crate:
- New 'hrtimer' module: add support for setting up intrusive timers
without allocating when starting the timer. Add support for
'Pin<Box<_>>', 'Arc<_>', 'Pin<&_>' and 'Pin<&mut _>' as pointer types
for use with timer callbacks. Add support for setting clock source
and timer mode.
- New 'dma' module: add a simple DMA coherent allocator abstraction and
a test sample driver.
- 'list' module: make the linked list 'Cursor' point between elements,
rather than at an element, which is more convenient to us and allows
for cursors to empty lists; and document it with examples of how to
perform common operations with the provided methods.
- 'str' module: implement a few traits for 'BStr' as well as the
'strip_prefix()' method.
- 'sync' module: add 'Arc::as_ptr'.
- 'alloc' module: add 'Box::into_pin'.
- 'error' module: extend the 'Result' documentation, including a few
examples on different ways of handling errors, a warning about using
methods that may panic, and links to external documentation.
'macros' crate:
- 'module' macro: add the 'authors' key to support multiple authors.
The original key will be kept until everyone has migrated.
Documentation:
- Add error handling sections.
MAINTAINERS:
- Add Danilo Krummrich as reviewer of the Rust "subsystem".
- Add 'RUST [PIN-INIT]' entry with Benno Lossin as maintainer. It has
its own sub-tree.
- Add sub-tree for 'RUST [ALLOC]'.
- Add 'DMA MAPPING HELPERS DEVICE DRIVER API [RUST]' entry with Abdiel
Janulgue as primary maintainer. It will go through the sub-tree of
the 'RUST [ALLOC]' entry.
- Add 'HIGH-RESOLUTION TIMERS [RUST]' entry with Andreas Hindborg as
maintainer. It has its own sub-tree.
And a few other cleanups and improvements.

Modules changes for 6.15-rc1
- Use RCU instead of RCU-sched
The mix of rcu_read_lock(), rcu_read_lock_sched() and preempt_disable()
in the module code and its users has been replaced with just
rcu_read_lock().
- The rest of changes are smaller fixes and updates.
The changes have been on linux-next for at least 2 weeks, with the RCU
cleanup present for 2 months. One performance problem was reported with the
RCU change when KASAN + lockdep were enabled, but it was effectively
addressed by the already merged

slab wrappers: bpf_mem_alloc, kretprobe's objpool, etc. These patches
make page allocator safe from any context.
Vlastimil kicked off this effort at LSFMM 2024:
https://lwn.net/Articles/974138/
and we continued at LSFMM 2025:
https://lore.kernel.org/all/CAADnVQKfkGxudNUkcPJgwe3nTZ=xohnRshx9kLZBTmR_E1DFEg@mail.gmail.com/
Why:
SLAB wrappers bind memory to a particular subsystem making it
unavailable to the rest of the kernel. Some BPF maps in production
consume Gbytes of preallocated memory. Top 5 in Meta: 1.5G, 1.2G,
1.1G, 300M, 200M. Once we have kmalloc that works in any context BPF
map preallocation won't be necessary.
How:
Synchronous kmalloc/page alloc stack has multiple stages going from
fast to slow: cmpxchg16 -> slab_alloc -> new_slab -> alloc_pages ->
rmqueue_pcplist -> __rmqueue, where rmqueue_pcplist was already
relying on trylock.
This set changes rmqueue_bulk/rmqueue_buddy to attempt a trylock and
return ENOMEM if alloc_flags & ALLOC_TRYLOCK. It then wraps this
functionality into try_alloc_pages() helper. We make sure that the
logic is sane in PREEMPT_RT.
End result: try_alloc_pages()/free_pages_nolock() are safe to call
from any context.
try_kmalloc() for any context with similar trylock approach will
follow. It will use try_alloc_pages() when slab needs a new page.
Though such try_kmalloc/page_alloc() is an opportunistic allocator,
this design ensures that the probability of successful allocation of
small objects (up to one page in size) is high.
Even before we have try_kmalloc(), we already use try_alloc_pages() in
BPF arena implementation and it's going to be used more extensively in
BPF"

Merge tag 'bpf_res_spin_lock' of git://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next
Pull bpf relisient spinlock support from Alexei Starovoitov:
"This patch set introduces Resilient Queued Spin Lock (or rqspinlock
with res_spin_lock() and res_spin_unlock() APIs).
This is a qspinlock variant which recovers the kernel from a stalled
state when the lock acquisition path cannot make forward progress.
This can occur when a lock acquisition attempt enters a deadlock
situation (e.g. AA, or ABBA), or more generally, when the owner of the
lock (which we’re trying to acquire) isn’t making forward progress.
Deadlock detection is the main mechanism used to provide instant
recovery, with the timeout mechanism acting as a final line of
defense. Detection is triggered immediately when beginning the waiting
loop of a lock slow path.
Additionally, BPF programs attached to different parts of the kernel
can introduce new control flow into the kernel, which increases the
likelihood of deadlocks in code not written to handle reentrancy.
There have been multiple syzbot reports surfacing deadlocks in
internal kernel code due to the diverse ways in which BPF programs can
be attached to different parts of the kernel. By switching the BPF
subsystem’s lock usage to rqspinlock, all of these issues are
mitigated at runtime.
This spin lock implementation allows BPF maps to become safer and
remove mechanisms that have fallen short in assuring safety when
nesting programs in arbitrary ways in the same context or across
different contexts.
We run benchmarks that stress locking scalability and perform
comparison against the baseline (qspinlock). For the rqspinlock case,
we replace the default qspinlock with it in the kernel, such that all
spin locks in the kernel use the rqspinlock slow path. As such,
benchmarks that stress kernel spin locks end up exercising rqspinlock.

Here's the pile of clk driver patches. The usual suspects^Wsilicon
vendors are all here, adding new SoC support and fixing existing code.
There are a few patches to the clk framework here as well. They've been
baking in linux-next for weeks so I'm hoping we don't have to revert
them. The disable OF node patch is probably the scariest one although it
seems unlikely that a system would be relying on a driver _not_ probing
because the clk never appeared, but you never know. Nothing looks out of
the ordinary on the driver side but that's because it's mostly a bunch
of data.
Core:
- Use dev_err_probe() in the clk registration path (Peering into the
crystal ball shows many patches that remove printks)
- Check for disabled OF nodes in of_clk_get_hw_from_clkspec()
New Drivers:
- Allwinner A523/T527 clk driver
- Qualcomm IPQ9574 NSS clk driver
- Qualcomm QCS8300 GPU and video clk drivers
- Qualcomm SDM429 RPM clks
- Qualcomm QCM6490 LPASS (low power audio) resets
- Samsung Exynos2200: driver for several clock controllers (Alive,
CMGP, HSI, PERIC/PERIS, TOP, UFS and VFS)
- Samsung Exynos7870: Driver for several clock controllers (Alive, MIF,
DISP AUD, FSYS, G3D, ISP, MFC and PERI)
- Rockchip rk3528 and rk3562 clk driver
Updates:
- Various fixes to SoC clk drivers for incorrect data, avoid touching
protected registers, etc.
- Additions for some missing clks in existing SoC clk drivers
- DT schema conversions from text to YAML
- Kconfig cleanups to allow drivers to be compiled on moar
architectures

s390 updates for 6.15 merge window
- Add sorting of mcount locations at build time - Rework uaccess functions with C exception handling to shorten inline assembly size and enable full inlining. This yields near-optimal code for small constant copies with a ~40kb kernel size increase - Add support for a configurable STRICT_MM_TYPECHECKS which allows to generate better code, but also allows to have type checking for debug builds - Optimize get_lowcore() for common callers with alternatives that nearly revert to the pre-relocated lowcore code, while also slightly reducing syscall entry and exit time - Convert MACHINE_HAS_* checks for single facility tests into cpu_has_* style macros that call test_facility(), and for features with additional conditions, add a new ALT_TYPE_FEATURE alternative to provide a static branch via alternative patching. Also, move machine feature detection to the decompressor for early patching and add debugging functionality to easily show which alternatives are patched - Add exception table support to early boot / startup code to get rid of the open coded exception handling - Use asm_inline for all inline assemblies with EX_TABLE or ALTERNATIVE to ensure correct inlining and unrolling decisions - Remove 2k page table leftovers now that s390 has been switched to always allocate 4k page tables - Split kfence pool into 4k mappings in arch_kfence_init_pool() and remove the architecture-specific kfence_split_mapping() - Use READ_ONCE_NOCHECK() in regs_get_kernel_stack_nth() to silence spurious KASAN warnings from opportunistic ftrace argument tracing - Force __atomic_add_const() variants on s390 to always return void, ensuring compile errors for improper usage - Remove s390's ioremap_wt() and pgprot_writethrough() due to mismatched semantics and lack of known users, relying on asm-generic fallbacks - Signal eventfd in vfio-ap to notify userspace when the guest AP configuration changes, including during mdev removal - Convert mdev_types from an array to a pointer in vfio-ccw and vfio-ap drivers to avoid fake flex array confusion - Cleanup trap code - Remove references to the outdated linux390@de.ibm.com address - Other various small fixes and improvements all over the code -----BEGIN PGP SIGNATURE----- iQEzBAABCAAdFiEE3QHqV+H2a8xAv27vjYWKoQLXFBgFAmfmuPwACgkQjYWKoQLX FBgTDAgAjKmZ5OYjACRfYepTvKk9SDqa2CBlQZ+BhbAXEVIrxKnv8OkImAXoWNsM mFxiCxAHWdcD+nqTrxFsXhkNLsndijlwnj/IqZgvy6R/3yNtBlAYRPLujOmVrsQB dWB8Dl38p63Ip1JfAqyabiAOUjfhrclRcM5FX5tgciXA6N/vhY3OM6k0+k7wN4Nj Dei/rCrnYRXTrFQgtM4w8JTIrwdnXjeKvaTYCflh4Q5ISJ7TceSF7cqq8HOs5hhK o2ciaoTdx212522CIsxeN3Ls3jrn8bCOCoOeSCysc5RL84grAuFnmjSajo1LFide S/TQtHXYy78Wuei9xvHi561ogiv/ww== =Kxgc -----END PGP SIGNATURE----- Merge tag 's390-6.15-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux Pull s390 updates from Vasily Gorbik: - Add sorting of mcount locations at build time - Rework uaccess functions with C exception handling to shorten inline assembly size and enable full inlining.

fwctl first pull request
fwctl is a new subsystem intended to bring some common rules and order to the growing pattern of exposing a secure FW interface directly to userspace. Unlike existing places like RDMA/DRM/VFIO/uacce that are exposing a device for datapath operations fwctl is focused on debugging, configuration and provisioning of the device. It will not have the necessary features like interrupt delivery to support a datapath. This concept is similar to the long standing practice in the "HW" RAID space of having a device specific misc device to manage the RAID controller FW. fwctl generalizes this notion of a companion debug and management interface that goes along with a dataplane implemented in an appropriate subsystem. There have been three LWN articles written discussing various aspects of this: https://lwn.net/Articles/955001/ https://lwn.net/Articles/969383/ https://lwn.net/Articles/990802/ This pull requests includes three drivers to launch the subsystem: - CXL provides a vendor scheme for executing commands and a way to learn the 'command effects' (ie the security properties) of such commands. The fwctl driver allows access to these mechanism within the fwctl security model - mlx5 is family of networking products, the driver supports all current Mellanox HW still receiving FW feature updates. This includes RDMA multiprotocol NICs like ConnectX and the Bluefield family of Smart NICs. - AMD/Pensando Distributed Services card is a multi protocol Smart NIC with a multi PCI function design. fwctl works on the management PCI function following a 'command effects' model similar to CXL. -----BEGIN PGP SIGNATURE----- iHUEABYKAB0WIQRRRCHOFoQz/8F5bUaFwuHvBreFYQUCZ939zQAKCRCFwuHvBreF YdOoAQCJq59/UC7lXU+sOsR6LISaDVTT5jAweBo0o036P9+DNAEA1iQdZ/GK2yCJ Ub33Xo9L+hzIpIbCouI3BtCXqymybAg= =f5YG -----END PGP SIGNATURE----- Merge tag 'for-linus-fwctl' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma Pull fwctl subsystem from Jason Gunthorpe: "fwctl is a new subsystem intended to bring some common rules and order to the growing pattern of exposing a secure FW interface directly to userspace.

Merge tag 'pci-v6.15-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci
Pull pci updates from Bjorn Helgaas:
"Enumeration:
- Enable Configuration RRS SV, which makes device readiness visible,
early instead of during child bus scanning (Bjorn Helgaas)
- Log debug messages about reset methods being used (Bjorn Helgaas)
- Avoid reset when it has been disabled via sysfs (Nishanth
Aravamudan)
- Add common pci-ep-bus.yaml schema for exporting several peripherals
of a single PCI function via devicetree (Andrea della Porta)
- Create DT nodes for PCI host bridges to enable loading device tree
overlays to create platform devices for PCI devices that have
several features that require multiple drivers (Herve Codina)
Resource management:
- Enlarge devres table[] to accommodate bridge windows, ROM, IOV
BARs, etc., and validate BAR index in devres interfaces (Philipp
Stanner)
- Fix typo that repeatedly distributed resources to a bridge instead
of iterating over subordinate bridges, which resulted in too little
space to assign some BARs (Kai-Heng Feng)
- Relax bridge window tail sizing for optional resources, e.g., IOV
BARs, to avoid failures when removing and re-adding devices (Ilpo
Järvinen)
- Allow drivers to enable devices even if we haven't assigned
optional IOV resources to them (Ilpo Järvinen)
- Rework handling of optional resources (IOV BARs, ROMs) to reduce
failures if we can't allocate them (Ilpo Järvinen)
- Fix a NULL dereference in the SR-IOV VF creation error path (Shay
Drory)
- Fix s390 mmio_read/write syscalls, which didn't cause page faults
in some cases, which broke vfio-pci lazy mapping on first access
(Niklas Schnelle)
- Add pdev->non_mappable_bars to replace CONFIG_VFIO_PCI_MMAP, which
was disabled only for s390 (Niklas Schnelle)
- Support mmap of PCI resources on s390 except for ISM devices
(Niklas Schnelle)
ASPM:
- Delay pcie_link_state deallocation to avoid dangling pointers that
cause invalid references during hot-unplug (Daniel Stodden)
Power management:
- Allow PCI bridges to go to D3Hot when suspending on all non-x86
systems (Manivannan Sadhasivam)
Power control:
- Create pwrctrl devices in pci_scan_device() to make it more
symmetric with pci_pwrctrl_unregister() and make pwrctrl devices
for PCI bridges possible (Manivannan Sadhasivam)
- Unregister pwrctrl devices in pci_destroy_dev() so DOE, ASPM, etc.
can still access devices after pci_stop_dev() (Manivannan
Sadhasivam)
- If there's a pwrctrl device for a PCI device, skip scanning it
because the pwrctrl core will rescan the bus after the device is
powered on (Manivannan Sadhasivam)
- Add a pwrctrl driver for PCI slots based on voltage regulators
described via devicetree (Manivannan Sadhasivam)
Bandwidth control:
- Add set_pcie_speed.sh to TEST_PROGS to fix issue when executing the
set_pcie_cooling_state.sh test case (Yi Lai)
- Avoid a NULL pointer dereference when we run out of bus numbers to
assign for a bridge secondary bus (Lukas Wunner)
Hotplug:
- Drop superfluous pci_hotplug_slot_list, try_module_get() calls, and
NULL pointer checks (Lukas Wunner)
- Drop shpchp module init/exit logging, replace shpchp dbg() with
ctrl_dbg(), and remove unused dbg(), err(), info(), warn() wrappers
(Ilpo Järvinen)
- Drop 'shpchp_debug' module parameter in favor of standard dynamic
debugging (Ilpo Järvinen)
- Drop unused cpcihp .get_power(), .set_power() function pointers
(Guilherme Giacomo Simoes)
- Disable hotplug interrupts in portdrv only when pciehp is not
enabled to avoid issuing two hotplug commands too close together
(Feng Tang)
- Skip pciehp 'device replaced' check if the device has been removed
to address a deadlock when resuming after a device was removed
during system sleep (Lukas Wunner)
- Don't enable pciehp hotplug interupt when resuming in poll mode
(Ilpo Järvinen)
Virtualization:
- Fix bugs in 'pci=config_acs=' kernel command line parameter (Tushar
Dave)
DOE:
- Expose supported DOE features via sysfs (Alistair Francis)
- Allow DOE support to be enabled even if CXL isn't enabled (Alistair
Francis)
Endpoint framework:
- Convert PCI device data so pci-epf-test works correctly on
big-endian endpoint systems (Niklas Cassel)
- Add BAR_RESIZABLE type to endpoint framework and add DWC core
support for EPF drivers to set BAR_RESIZABLE type and size (Niklas
Cassel)
- Fix pci-epf-test double free that causes an oops if the host
reboots and PERST# deassertion restarts endpoint BAR allocation
(Christian Bruel)
- Fix endpoint BAR testing so tests can skip disabled BARs instead of
reporting them as failures (Niklas Cassel)
- Widen endpoint test BAR size variable to accommodate BARs larger
than INT_MAX (Niklas Cassel)
- Remove unused tools 'pci' build target left over after moving tests
to tools/testing/selftests/pci_endpoint (Jianfeng Liu)

first (Stanimir Varbanov)
- Expand inbound window map to 64GB so it can accommodate BCM2712
(Stanimir Varbanov)
- Add BCM2712 support and DT updates (Stanimir Varbanov)
- Apply link speed restriction before bringing link up, not after
(Jim Quinlan)
- Update Max Link Speed in Link Capabilities via the internal
writable register, not the read-only config register (Jim Quinlan)
- Handle regulator_bulk_get() error to avoid panic when we call
regulator_bulk_free() later (Jim Quinlan)
- Disable regulators only when removing the bus immediately below a
Root Port because we don't support regulators deeper in the
hierarchy (Jim Quinlan)
- Make const read-only arrays static (Colin Ian King)
Cadence PCIe endpoint driver:
- Correct MSG TLP generation so endpoints can generate INTx messages
(Hans Zhang)
Freescale i.MX6 PCIe controller driver:
- Identify the second controller on i.MX8MQ based on devicetree
'linux,pci-domain' instead of DBI 'reg' address (Richard Zhu)

Intel VMD host bridge driver:
- Convert vmd_dev.cfg_lock from spinlock_t to raw_spinlock_t so
pci_ops.read() will never sleep, even on PREEMPT_RT where
spinlock_t becomes a sleepable lock, to avoid calling a sleeping
function from invalid context (Ryo Takakura)
MediaTek PCIe Gen3 controller driver:
- Remove leftover mac_reset assert for Airoha EN7581 SoC (Lorenzo

Merge tag 'drm-next-2025-03-28' of https://gitlab.freedesktop.org/drm/kernel
Pull drm updates from Dave Airlie:
"Outside of drm there are some rust patches from Danilo who maintains
that area in here, and some pieces for drm header check tests.
The major things in here are a new driver supporting the touchbar
displays on M1/M2, the nova-core stub driver which is just the vehicle
for adding rust abstractions and start developing a real driver inside
of.
xe adds support for SVM with a non-driver specific SVM core
abstraction that will hopefully be useful for other drivers, along
with support for shrinking for TTM devices. I'm sure xe and AMD
support new devices, but the pipeline depth on these things is hard to
know what they end up being in the marketplace!

For that case, they then need to add the io_uring fd to the epoll context, and continue to rely on epoll_wait(2) for waiting on events. This misses out on the finer grained waiting that io_uring can do, to reduce context switches and wait for multiple events in one batch reliably.

Pull io_uring zero-copy receive support from Jens Axboe:
"This adds support for zero-copy receive with io_uring, enabling fast
bulk receive of data directly into application memory, rather than
needing to copy the data out of kernel memory.
While this version only supports host memory as that was the initial
target, other memory types are planned as well, with notably GPU
memory coming next.
This work depends on some networking components which were queued up
on the networking side, but have now landed in your tree.
This is the work of Pavel Begunkov and David Wei. From the v14 posting:
'We configure a page pool that a driver uses to fill a hw rx queue
to hand out user pages instead of kernel pages. Any data that ends
up hitting this hw rx queue will thus be dma'd into userspace
memory directly, without needing to be bounced through kernel
memory. 'Reading' data out of a socket instead becomes a
_notification_ mechanism, where the kernel tells userspace where
the data is. The overall approach is similar to the devmem TCP
proposal
This relies on hw header/data split, flow steering and RSS to
ensure packet headers remain in kernel memory and only desired
flows hit a hw rx queue configured for zero copy. Configuring this
is outside of the scope of this patchset.
We share netdev core infra with devmem TCP. The main difference is
that io_uring is used for the uAPI and the lifetime of all objects
are bound to an io_uring instance. Data is 'read' using a new
io_uring request type. When done, data is returned via a new shared
refill queue. A zero copy page pool refills a hw rx queue from this
refill queue directly. Of course, the lifetime of these data
buffers are managed by io_uring rather than the networking stack,
with different refcounting rules.
This patchset is the first step adding basic zero copy support. We
will extend this iteratively with new features e.g. dynamically
allocated zero copy areas, THP support, dmabuf support, improved
copy fallback, general optimisations and more'
In a local setup, I was able to saturate a 200G link with a single CPU
core, and at netdev conf 0x19 earlier this month, Jamal reported
188Gbit of bandwidth using a single core (no HT, including soft-irq).
Safe to say the efficiency is there, as bigger links would be needed
to find the per-core limit, and it's considerably more efficient and
faster than the existing devmem solution"

Hi,
This PR contains a new driver: TPM FF-A driver. FF comes from Firmware
Framework, and A comes from Arm's A-profile [1]. FF-A is essentially
a standard mechanism to communicate with TrustZone apps such as TPM.
Other than that, the PR includes a pile of fixes and small improvments.

module: Add module_for_each_mod() function
The tracing system needs a way to save all the currently loaded modules and their addresses into persistent memory so that it can evaluate the addresses on a reboot from a crash. When the persistent memory trace starts, it will load the module addresses and names into the persistent memory. To do so, it will call the module_for_each_mod() function and pass it a function and data structure to get called on each loaded module. Then it can record the memory. This only implements that function.

ring-buffer: Add ring_buffer_meta_scratch()
Now that there's one meta data at the start of the persistent memory used by the ring buffer, allow the caller to request some memory right after that data that it can use as its own persistent memory. Also fix some white space issues with ring_buffer_alloc().

ring-buffer: Use kaslr address instead of text delta
Instead of saving off the text and data pointers and using them to compare with the current boot's text and data pointers, just save off the KASLR offset. Then that can be used to figure out how to read the previous boots buffer. The last_boot_info will now show this offset, but only if it is for a previous boot: ~# cat instances/boot_mapped/last_boot_info 39000000 [kernel] ~# echo function > instances/boot_mapped/current_tracer ~# cat instances/boot_mapped/last_boot_info # Current If the KASLR offset saved is for the current boot, the last_boot_info will show the value of "current".

tracing updates for v6.15:
- Add option traceoff_after_boot In order to debug kernel boot, it sometimes is helpful to enable tracing via the kernel command line. Unfortunately, by the time the login prompt appears, the trace is overwritten by the init process and other user space start up applications. Adding a "traceoff_after_boot" will disable tracing when the kernel passes control to init which will allow developers to be able to see the traces that occurred during boot. - Clean up the mmflags macros that display the GFP flags in trace events The macros to print the GFP flags for trace events had a bit of duplication. The code was restructured to remove duplication and in the process it also adds some flags that were missed before. - Removed some dead code and scripts/draw_functrace.py draw_functrace.py hasn't worked in years and as nobody complained about it, remove it. - Constify struct event_trigger_ops The event_trigger_ops is just a structure that has function pointers that are assigned when the variables are created.

Latency tracing changes for v6.15:
- Add some trace events to osnoise and timerlat sample generation
This adds more information to the osnoise and timerlat tracers as well as
allows BPF programs to be attached to these locations to extract even more
data.
- Fix to DECLARE_TRACE_CONDITION() macro
It wasn't used but now will be and it happened to be broken causing the
build to fail.
- Add scheduler specification monitors to runtime verifier (RV)
This is a continuation of Daniel Bristot's work.
RV allows monitors to run and react concurrently. Running the cumulative
model is equivalent to running single components using the same
reactors, with the advantage that it's easier to point out which
specification failed in case of error.
This update introduces nested monitors to RV, in short, the sysfs
monitor folder will contain a monitor named sched, which is nothing but
an empty container for other monitors. Controlling the sched monitor
(enable, disable, set reactors) controls all nested monitors.
The following scheduling monitors are added:
* sco: scheduling context operations
Monitor to ensure sched_set_state happens only in thread context
* tss: task switch while scheduling
Monitor to ensure sched_switch happens only in scheduling context
* snroc: set non runnable on its own context
Monitor to ensure set_state happens only in the respective task's context
* scpd: schedule called with preemption disabled
Monitor to ensure schedule is called with preemption disabled
* snep: schedule does not enable preempt
Monitor to ensure schedule does not enable preempt
* sncid: schedule not called with interrupt disabled
Monitor to ensure schedule is not called with interrupt disabled

ftrace changes for v6.15:
- Record function parameters for function and function graph tracers
An option has been added to function tracer (func-args) and the function
graph tracer (funcgraph-args) that when set, the tracers will record the
registers that hold the arguments into each function event. On reading of
the trace, it will use BTF to print those arguments. Most archs support up
to 6 arguments (depending on the complexity of the arguments) and those
are printed. If a function has more arguments then what was recorded, the
output will end with " ... )".
Example of function graph tracer:
6) | dummy_xmit [dummy](skb = 0x8887c100, dev = 0x872ca000) {
6) | consume_skb(skb = 0x8887c100) {
6) | skb_release_head_state(skb = 0x8887c100) {
6) 0.178 us | sock_wfree(skb = 0x8887c100)
6) 0.627 us | }
- The rest of the changes are minor clean ups and fixes

* avoid potentially BUG'ing if there is a file system corruption found
during the file system unmount
* fix free space reporting by statfs when project quotas are enabled

f2fs-for-6.15-rc1
In this round, there are three major updates: 1) folio conversion, 2) refactor for mount API conversion, 3) some performance improvement such as direct IO, checkpoint speed, and IO priority hints. For stability, there are patches which add more sanity checks and fixes some major issues like i_size in atomic write operations and write pointer recovery in zoned devices.

Pull btrfs updates from David Sterba:
"User visible changes:
- fall back to buffered write if direct io is done on a file that
requires checksums
- this avoids a problem with checksum mismatch errors, observed
e.g. on virtual images when writes to pages under writeback
cause the checksum mismatch reports
- this may lead to some performance degradation but currently the
recommended setup for VM images is to use the NOCOW file
attribute that also disables checksums
- fast/realtime zstd levels -15 to -1
- supported by mount options (compress=zstd:-5) and defrag ioctl
- improved speed, reduced compression ratio, check the commit for
sample measurements
- defrag ioctl extended to accept negative compression levels
- subpage mode
- remove warning when subpage mode is used, the feature is now
reasonably complete and tested
- in debug mode allow to create 2K b-tree nodes to allow testing
subpage on x86_64 with 4K pages too
Performance improvements:
- in send, better file path caching improves runtime (on sample load
by -30%)
- on s390x with hardware zlib support prepare the input buffer in a
better way to get the best results from the acceleration
- minor speed improvement in encoded read, avoid memory allocation in
synchronous mode
Core:
- enable stable writes on inodes, replacing manually waiting for
writeback and allowing to skip that on inodes without checksums
- add last checks and warnings for out-of-band dirty writes to pages,
requiring a fixup ("fixup worker"), this should not be necessary
since 5.8 where get_user_page() and pin_user_pages*() prevent this
- long history behind that, we'll be happy to remove the whole
infrastructure in the near future
- more folio API conversions and preparations for large folio support
- subpage cleanups and refactoring, split handling of data and
metadata to allow future support for large folios
- readpage works as block-by-block, no change for normal mode, this
is preparation for future subpage updates
- block group refcount fixes and hardening
- delayed iput fixes
- in zoned mode, fix zone activation on filesystem with missing
devices
Cleanups:
- inode parameter cleanups
- path auto-freeing updates
- code flow simplifications in send
- redundant parameter cleanups"

Pull erofs updates from Gao Xiang:
"In this cycle, EROFS 48-bit block addressing is available to support
massive datasets for model training and other large data archive use
cases.
In addition, byte-oriented encoded extents have been supported to
reduce metadata sizes when using large configurations as well as to
improve Zstd compression speed.
There are some bugfixes and cleanups as usual.
Summary:
- Support 48-bit block addressing for large images
- Introduce encoded extents to reduce metadata on larger pclusters
- Enable unaligned compressed data to improve Zstd compression speed
- Allow 16-byte volume names again
