Pull PCI updates from Bjorn Helgaas:
"Enumeration:
- Allow built-in drivers, not just modular drivers, to use async
initial probing (Lukas Wunner)
- Support Immediate Readiness even on devices with no PM Capability
(Sean Christopherson)
- Consolidate definition of PCIE_RESET_CONFIG_WAIT_MS (100ms), the
required delay between a reset and sending config requests to a
device (Niklas Cassel)
- Add pci_is_display() to check for "Display" base class and use it
in ALSA hda, vfio, vga_switcheroo, vt-d (Mario Limonciello)
- Allow 'isolated PCI functions' (multi-function devices without a
function 0) for LoongArch, similar to s390 and jailhouse (Huacai
Chen)
Power control:
- Add ability to enable optional slot clock for cases where the PCIe
host controller and the slot are supplied by different clocks
(Marek Vasut)
PCIe native device hotplug:
- Fix runtime PM ref imbalance on Hot-Plug Capable ports caused by
misinterpreting a config read failure after a device has been
removed (Lukas Wunner)
- Avoid creating a useless PCIe port service device for pciehp if the
slot is handled by the ACPI hotplug driver (Lukas Wunner)
- Ignore ACPI hotplug slots when calculating depth of pciehp hotplug
ports (Lukas Wunner)
Virtualization:
- Save VF resizable BAR state and restore it after reset (Michał
Winiarski)
- Allow IOV resources (VF BARs) to be resized (Michał Winiarski)
- Add pci_iov_vf_bar_set_size() so drivers can control VF BAR size
(Michał Winiarski)
Endpoint framework:
- Add RC-to-EP doorbell support using platform MSI controller,
including a test case (Frank Li)
- Allow BAR assignment via configfs so platforms have flexibility in
determining BAR usage (Jerome Brunet)
Native PCIe controller drivers:
- Convert amazon,al-alpine-v[23]-pcie, apm,xgene-pcie,
axis,artpec6-pcie, marvell,armada-3700-pcie, st,spear1340-pcie to
DT schema format (Rob Herring)
- Use dev_fwnode() instead of of_fwnode_handle() to remove OF
dependency in altera (fixes an unused variable), designware-host,
mediatek, mediatek-gen3, mobiveil, plda, xilinx, xilinx-dma,
xilinx-nwl (Jiri Slaby, Arnd Bergmann)
- Convert aardvark, altera, brcmstb, designware-host, iproc,
mediatek, mediatek-gen3, mobiveil, plda, rcar-host, vmd, xilinx,
xilinx-dma, xilinx-nwl from using pci_msi_create_irq_domain() to
using msi_create_parent_irq_domain() instead; this makes the
interrupt controller per-PCI device, allows dynamic allocation of
vectors after initialization, and allows support of IMS (Nam Cao)
APM X-Gene PCIe controller driver:
- Rewrite MSI handling to MSI CPU affinity, drop useless CPU hotplug
bits, use device-managed memory allocations, and clean things up
(Marc Zyngier)
- Probe xgene-msi as a standard platform driver rather than a
subsys_initcall (Marc Zyngier)
Broadcom STB PCIe controller driver:
- Add optional DT 'num-lanes' property and if present, use it to
override the Maximum Link Width advertised in Link Capabilities
(Jim Quinlan)
Cadence PCIe controller driver:
- Use PCIe Message routing types from the PCI core rather than
defining private ones (Hans Zhang)
Freescale i.MX6 PCIe controller driver:
- Add IMX8MQ_EP third 64-bit BAR in epc_features (Richard Zhu)
- Add IMX8MM_EP and IMX8MP_EP fixed 256-byte BAR 4 in epc_features
(Richard Zhu)
- Configure LUT for MSI/IOMMU in Endpoint mode so Root Complex can
trigger doorbel on Endpoint (Frank Li)
- Remove apps_reset (LTSSM_EN) from
imx_pcie_{assert,deassert}_core_reset(), which fixes a hotplug
regression on i.MX8MM (Richard Zhu)
- Delay Endpoint link start until configfs 'start' written (Richard
Zhu)
Intel VMD host bridge driver:
- Add Intel Panther Lake (PTL)-H/P/U Vendor ID (George D Sworo)
Qualcomm PCIe controller driver:
- Add DT binding and driver support for SA8255p, which supports ECAM
for Configuration Space access (Mayank Rana)
- Update DT binding and driver to describe PHYs and per-Root Port
resets in a Root Port stanza and deprecate describing them in the
host bridge; this makes it possible to support multiple Root Ports
in the future (Krishna Chaitanya Chundru)
- Add Qualcomm QCS615 to SM8150 DT binding (Ziyue Zhang)
- Add Qualcomm QCS8300 to SA8775p DT binding (Ziyue Zhang)
- Drop TBU and ref clocks from Qualcomm SM8150 and SC8180x DT
bindings (Konrad Dybcio)
- Document 'link_down' reset in Qualcomm SA8775P DT binding (Ziyue
Zhang)
- Add required PCIE_RESET_CONFIG_WAIT_MS delay after Link up IRQ
(Niklas Cassel)
Rockchip PCIe controller driver:
- Drop unused PCIe Message routing and code definitions (Hans Zhang)
- Remove several unused header includes (Hans Zhang)
- Use standard PCIe config register definitions instead of
rockchip-specific redefinitions (Geraldo Nascimento)
- Set Target Link Speed to 5.0 GT/s before retraining so we have a
chance to train at a higher speed (Geraldo Nascimento)
Rockchip DesignWare PCIe controller driver:
- Prevent race between link training and register update via DBI by
inhibiting link training after hot reset and link down (Wilfred
Mallawa)
- Add required PCIE_RESET_CONFIG_WAIT_MS delay after Link up IRQ
(Niklas Cassel)
Sophgo PCIe controller driver:
- Add DT binding and driver for Sophgo SG2044 PCIe controller driver
in Root Complex mode (Inochi Amaoto)
Synopsys DesignWare PCIe controller driver:
- Add required PCIE_RESET_CONFIG_WAIT_MS after waiting for Link up on
Ports that support > 5.0 GT/s. Slower Ports still rely on the
not-quite-correct PCIE_LINK_WAIT_SLEEP_MS 90ms default delay while
waiting for the Link (Niklas Cassel)"

tracing changes for 6.17
- Deprecate auto-mounting tracefs to /sys/kernel/debug/tracing
When tracefs was first introduced back in 2014, the directory
/sys/kernel/tracing was added and is the designated location to mount
tracefs. To keep backward compatibility, tracefs was auto-mounted in
/sys/kernel/debug/tracing as well.
All distros now mount tracefs on /sys/kernel/tracing. Having it seen in two
different locations has lead to various issues and inconsistencies.
The VFS folks have to also maintain debugfs_create_automount() for this
single user.
It's been over 10 years. Tooling and scripts should start replacing the
debugfs location with the tracefs one. The reason tracefs was created in the
first place was to allow access to the tracing facilities without the need
to configure debugfs into the kernel. Using tracefs should now be more
robust.
A new config is created: CONFIG_TRACEFS_AUTOMOUNT_DEPRECATED
which is default y, so that the kernel is still built with the automount.
This config allows those that want to remove the automount from debugfs to
do so.
When tracefs is accessed from /sys/kernel/debug/tracing, the following
printk is triggerd:
pr_warn("NOTICE: Automounting of tracing to debugfs is deprecated and will be removed in 2030\n");
This gives users another 5 years to fix their scripts.
- Use queue_rcu_work() instead of call_rcu() for freeing event filters
The number of filters to be free can be many depending on the number of
events within an event system. Freeing them from softirq context can
potentially cause undesired latency. Use the RCU workqueue to free them
instead.
- Remove pointless memory barriers in latency code
Memory barriers were added to some of the latency code a long time ago with
the idea of "making them visible", but that's not what memory barriers are
for. They are to synchronize access between different variables. There was
no synchronization here making them pointless.
- Remove "__attribute__()" from the type field of event format
When LLVM is used to compile the kernel with CONFIG_DEBUG_INFO_BTF=y and
PAHOLE_HAS_BTF_TAG=y, some of the format fields get expanded with the
following:
field:const char * filename; offset:24; size:8; signed:0;
Turns into:
field:const char __attribute__((btf_type_tag("user"))) * filename; offset:24; size:8; signed:0;
This confuses parsers. Add code to strip these tags from the strings.
- Add eprobe config option CONFIG_EPROBE_EVENTS
Eprobes were added back in 5.15 but were only enabled when another probe was
enabled (kprobe, fprobe, uprobe, etc). The eprobes had no config option
of their own. Add one as they should be a separate entity.
It's default y to keep with the old kernels but still has dependencies on
TRACING and HAVE_REGS_AND_STACK_ACCESS_API.
- Add eprobe documentation
When eprobes were added back in 5.15 no documentation was added to describe
them. This needs to be rectified.
- Replace open coded cpumask_next_wrap() in move_to_next_cpu()
- Have preemptirq_delay_run() use off-stack CPU mask
- Remove obsolete comment about pelt_cfs event
DECLARE_TRACE() appends "_tp" to trace events now, but the comment above
pelt_cfs still mentioned appending it manually.
- Remove EVENT_FILE_FL_SOFT_MODE flag
The SOFT_MODE flag was required when the soft enabling and disabling of
trace events was first introduced. But there was a bug with this approach
as it only worked for a single instance. When multiple users required soft
disabling and disabling the code was changed to have a ref count. The
SOFT_MODE flag is now set iff the ref count is non zero. This is redundant
and just reading the ref count is good enough.
- Fix typo in comment

tracing tools changes for 6.17:
- Introduce enum timerlat_tracing_mode
Now that BPF based sampling has been added to timerlat, add an enum to
represent which mode timerlat is running in.
- Add action on timelat threshold feature
A new option, --on-threshold, is added, taking an argument
that further specifies the action. Actions added in this patch are:
- trace[,file=<filename>]: Saves tracefs buffer, optionally taking a
filename.
- signal,num=<sig>,pid=<pid>: Sends signal to process. "parent" might
be specified instead of number to send signal to parent process.
- shell,command=<command>: Execute shell command.
- Allow resuming tracing in timerlat bpf
rtla-timerlat BPF program uses a global variable stored in a .bss section to
store whether tracing has been stopped. Map it to allow it to resume tracing
after it has been stopped.
- Add continue action to timerlat
Introduce option to resume tracing after a latency threshold overflow. The
option is implemented as an action named "continue".
- Add action on end feature to timerlat
Implement actions on end next to actions on threshold. A new option,
--on-end is added, parallel to --on-threshold. Instead of being executed
whenever a latency threshold is reached, it is executed at the end of the
measurement.
- Have rtla tests check output with grep
Add argument to the check command in the test suite that takes a regular
expression that the output of rtla command is checked against. This allows
testing for specific information in rtla output in addition to checking the
return value.
- Add tests for timerlat actions
- Update the documentation for the new features

Deferred unwind changes for 6.17
This is the core infrastructure for the deferred unwinder that is required for sframes[1]. Several other patch series is based on this work although those patch series are not dependent on each other. In order to simplify the development, having this core series upstream will allow the other series to be worked on in parallel. The other series are: - The two patches to implement x86: https://lore.kernel.org/linux-trace-kernel/20250717004958.260781923@kernel.org/ https://lore.kernel.org/linux-trace-kernel/20250717004958.432327787@kernel.org/ - The s390 work: https://lore.kernel.org/linux-trace-kernel/20250710163522.3195293-1-jremus@linux.ibm.com/ - The perf work: https://lore.kernel.org/linux-trace-kernel/20250718164119.089692174@kernel.org/ - The ftrace work: https://lore.kernel.org/linux-trace-kernel/20250424192612.505622711@goodmis.org/ - The sframe work: https://lore.kernel.org/linux-trace-kernel/20250717012848.927473176@kernel.org/ And more is on the way. The core infrastructure adds the following in kernel APIs: - int unwind_user_faultable(struct unwind_stacktrace *trace); Performs a user space stack trace that may fault user pages in. - int unwind_deferred_init(struct unwind_work *work, unwind_callback_t func); Allows a tracer to register with the unwind deferred infrastructure. - int unwind_deferred_request(struct unwind_work *work, u64 *cookie); Used when a tracer request a deferred trace. Can be called from interrupt or NMI context. - void unwind_deferred_cancel(struct unwind_work *work); Called by a tracer to unregister from the deferred unwind infrastructure. - void unwind_deferred_task_exit(struct task_struct *task); Called by task exit code to flush any pending unwind requests. - void unwind_task_init(struct task_struct *task); Called by do_fork() to initialize the task struct for the deferred unwinder. - void unwind_task_free(struct task_struct *task); Called by do_exit() to free up any resources used by the deferred unwinder. None of the above is actually compiled unless an architecture enables it, which none currently do.

vsock/virtio: Allocate nonlinear SKBs for handling large transmit buffers
When transmitting a vsock packet, virtio_transport_send_pkt_info() calls virtio_transport_alloc_linear_skb() to allocate and fill SKBs with the transmit data. Unfortunately, these are always linear allocations and can therefore result in significant pressure on kmalloc() considering that the maximum packet size (VIRTIO_VSOCK_MAX_PKT_BUF_SIZE + VIRTIO_VSOCK_SKB_HEADROOM) is a little over 64KiB, resulting in a 128KiB allocation for each packet. Rework the vsock SKB allocation so that, for sizes with page order greater than PAGE_ALLOC_COSTLY_ORDER, a nonlinear SKB is allocated instead with the packet header in the SKB and the transmit data in the fragments. Note that this affects both the vhost and virtio transports.

vhost/vsock: Allocate nonlinear SKBs for handling large receive buffers
When receiving a packet from a guest, vhost_vsock_handle_tx_kick() calls vhost_vsock_alloc_linear_skb() to allocate and fill an SKB with the receive data. Unfortunately, these are always linear allocations and can therefore result in significant pressure on kmalloc() considering that the maximum packet size (VIRTIO_VSOCK_MAX_PKT_BUF_SIZE + VIRTIO_VSOCK_SKB_HEADROOM) is a little over 64KiB, resulting in a 128KiB allocation for each packet.

Of the three callers of virtio_vsock_alloc_linear_skb(), only vhost_vsock_alloc_skb() can potentially pass a packet smaller than the header size and, as it already has a check against the maximum packet size, extend its bounds checking to consider the minimum packet size and remove the check from virtio_vsock_alloc_linear_skb().

vsock/virtio: Resize receive buffers so that each SKB fits in a 4K page
When allocating receive buffers for the vsock virtio RX virtqueue, an SKB is allocated with a 4140 data payload (the 44-byte packet header + VIRTIO_VSOCK_DEFAULT_RX_BUF_SIZE). Even when factoring in the SKB overhead, the resulting 8KiB allocation thanks to the rounding in kmalloc_reserve() is wasteful (~3700 unusable bytes) and results in a higher-order page allocation on systems with 4KiB pages just for the sake of a few hundred bytes of packet data. Limit the vsock virtio RX buffers to 4KiB per SKB, resulting in much better memory utilisation and removing the need to allocate higher-order pages entirely.

vsock/virtio: Move length check to callers of virtio_vsock_skb_rx_put()
virtio_vsock_skb_rx_put() only calls skb_put() if the length in the packet header is not zero even though skb_put() handles this case gracefully. Remove the functionally redundant check from virtio_vsock_skb_rx_put() and, on the assumption that this is a worthwhile optimisation for handling credit messages, augment the existing length checks in virtio_transport_rx_work() to elide the call for zero-length payloads. Since the callers all have the length, extend virtio_vsock_skb_rx_put() to take it as an additional parameter rather than fish it back out of the packet header. Note that the vhost code already has similar logic in vhost_vsock_alloc_skb().

vsock/virtio: Validate length in packet header before skb_put()
When receiving a vsock packet in the guest, only the virtqueue buffer
size is validated prior to virtio_vsock_skb_rx_put(). Unfortunately,
virtio_vsock_skb_rx_put() uses the length from the packet header as the
length argument to skb_put(), potentially resulting in SKB overflow if
the host has gone wonky.
Validate the length as advertised by the packet header before calling
virtio_vsock_skb_rx_put().

vhost/vsock: Avoid allocating arbitrarily-sized SKBs
vhost_vsock_alloc_skb() returns NULL for packets advertising a length
larger than VIRTIO_VSOCK_MAX_PKT_BUF_SIZE in the packet header. However,
this is only checked once the SKB has been allocated and, if the length
in the packet header is zero, the SKB may not be freed immediately.
Hoist the size check before the SKB allocation so that an iovec larger
than VIRTIO_VSOCK_MAX_PKT_BUF_SIZE + the header size is rejected
outright. The subsequent check on the length field in the header can
then simply check that the allocated SKB is indeed large enough to hold
the packet.

vhost_net: basic in_order support
This patch introduces basic in-order support for vhost-net. By recording the number of batched buffers in an array when calling `vhost_add_used_and_signal_n()`, we can reduce the number of userspace accesses. Note that the vhost-net batching logic is kept as we still count the number of buffers there. Testing Results: With testpmd: - TX: txonly mode + vhost_net with XDP_DROP on TAP shows a 17.5% improvement, from 4.75 Mpps to 5.35 Mpps. - RX: No obvious improvements were observed. With virtio-ring in-order experimental code in the guest: - TX: pktgen in the guest + XDP_DROP on TAP shows a 19% improvement, from 5.2 Mpps to 6.2 Mpps. - RX: pktgen on TAP with vhost_net + XDP_DROP in the guest achieves a 6.1% improvement, from 3.47 Mpps to 3.61 Mpps.

vhost: basic in order support
This patch adds basic in order support for vhost. Two optimizations are implemented in this patch: 1) Since driver uses descriptor in order, vhost can deduce the next avail ring head by counting the number of descriptors that has been used in next_avail_head. This eliminate the need to access the available ring in vhost. 2) vhost_add_used_and_singal_n() is extended to accept the number of batched buffers per used elem. While this increases the times of userspace memory access but it helps to reduce the chance of used ring access of both the driver and vhost. Vhost-net will be the first user for this.

vdpa: Fix IDR memory leak in VDUSE module exit
Add missing idr_destroy() call in vduse_exit() to properly free the
vduse_idr radix tree nodes. Without this, module load/unload cycles leak
576-byte radix tree node allocations, detectable by kmemleak as:
unreferenced object (size 576):
backtrace:
[<ffffffff81234567>] radix_tree_node_alloc+0xa0/0xf0
[<ffffffff81234568>] idr_get_free+0x128/0x280
The vduse_idr is initialized via DEFINE_IDR() at line 136 and used throughout
the VDUSE (vDPA Device in Userspace) driver for device ID management. The fix
follows the documented pattern in lib/idr.c and matches the cleanup approach
used by other drivers.
This leak was discovered through comprehensive module testing with cumulative
kmemleak detection across 10 load/unload iterations per module.

vdpa/mlx5: Fix release of uninitialized resources on error path
The commit in the fixes tag made sure that mlx5_vdpa_free()
is the single entrypoint for removing the vdpa device resources
added in mlx5_vdpa_dev_add(), even in the cleanup path of
mlx5_vdpa_dev_add().
This means that all functions from mlx5_vdpa_free() should be able to
handle uninitialized resources. This was not the case though:
mlx5_vdpa_destroy_mr_resources() and mlx5_cmd_cleanup_async_ctx()
were not able to do so. This caused the splat below when adding
a vdpa device without a MAC address.
This patch fixes these remaining issues:
- Makes mlx5_vdpa_destroy_mr_resources() return early if called on
uninitialized resources.
- Moves mlx5_cmd_init_async_ctx() early on during device addition
because it can't fail. This means that mlx5_cmd_cleanup_async_ctx()
also can't fail. To mirror this, move the call site of
mlx5_cmd_cleanup_async_ctx() in mlx5_vdpa_free().
An additional comment was added in mlx5_vdpa_free() to document
the expectations of functions called from this context.
Splat:

vdpa/mlx5: Fix needs_teardown flag calculation
needs_teardown is a device flag that indicates when virtual queues need
to be recreated. This happens for certain configuration changes: queue
size and some specific features.
Currently, the needs_teardown state can be incorrectly reset by
subsequent .set_vq_num() calls. For example, for 1 rx VQ with size 512
and 1 tx VQ with size 256:
.set_vq_num(0, 512) -> sets needs_teardown to true (rx queue has a
non-default size)
.set_vq_num(1, 256) -> sets needs_teardown to false (tx queue has a
default size)
This change takes into account the previous value of the needs_teardown
flag when re-calculating it during VQ size configuration.
