git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci Pull pci updates from Bjorn Helgaas: "Enumeration: - Allow TLP Processing Hints to be enabled for RCiEPs (George Abraham P) - Enable AtomicOps only if we know the Root Port supports them (Gerd Bayer) - Don't enable AtomicOps for RCiEPs since none of them need Atomic Ops and we can't tell whether the Root Complex would support them (Gerd Bayer) - Leave Precision Time Measurement disabled until a driver enables it to avoid PCIe errors (Mika Westerberg) - Make pci_set_vga_state() fail if bridge doesn't support VGA routing, i.e., PCI_BRIDGE_CTL_VGA is not writable, and return errors to vga_get() callers including userspace via /dev/vga_arbiter (Simon Richter) - Validate max-link-speed from DT in j721e, brcmstb, mediatek-gen3, rzg3s drivers (where the actual controller constraints are known), and remove validation from the generic OF DT accessor (Hans Zhang) - Remove pc110pad driver (no longer useful after 486 CPU support removed) and no_pci_devices() (pc110pad was the last user) (Dmitry Torokhov, Heiner Kallweit) Resource management: - Prevent assigning space to unimplemented bridge windows; previously we mistakenly assumed prefetchable window existed and assigned space and put a BAR there (Ahmed Naseef) - Avoid shrinking bridge windows to fit in the initial Root Port window; fixes one problem with devices with large BARs connected via switches, e.g., Thunderbolt (Ilpo Järvinen) - Pass full extent of empty space, not just the aligned space, to resource_alignf callback so free space before the requested alignment can be used (Ilpo Järvinen) - Place small resources before larger ones for better utilization of address space (Ilpo Järvinen) - Fix alignment calculation for resource size larger than align, e.g., bridge windows larger than the 1MB required alignment (Ilpo Järvinen) Reset: - Update slot handling so all ARI functions are treated as being in the same slot. They're all reset by Secondary Bus Reset, but previously drivers of ARI functions that appeared to be on a non-zero device weren't notified and fatal hardware errors could result (Keith Busch) - Make sysfs reset_subordinate hotplug safe to avoid spurious hotplug events (Keith Busch) - Hide Secondary Bus Reset ('bus') from sysfs reset_methods if masked by CXL because it has no effect (Vidya Sagar) - Avoid FLR for AMD NPU device, where it causes the device to hang (Lizhi Hou) Error handling: - Clear only error bits in PCIe Device Status to avoid accidentally clearing Emergency Power Reduction Detected (Shuai Xue) - Check for AER errors even in devices without drivers (Lukas Wunner) - Initialize ratelimit info so DPC and EDR paths log AER error information (Kuppuswamy Sathyanarayanan) Power control: - Add UPD720201/UPD720202 USB 3.0 xHCI Host Controller .compatible so generic pwrctrl driver can control it (Neil Armstrong) Hotplug: - Set LED_HW_PLUGGABLE for NPEM hotplug-capable ports so LED core doesn't complain when setting brightness fails because the endpoint is gone (Richard Cheng) Peer-to-peer DMA: - Allow wildcards in list of host bridges that support peer-to-peer DMA between hierarchy domains and add all Google SoCs (Jacob Moroni) Endpoint framework: - Advertise dynamic inbound mapping support in pci-epf-test and update host pci_endpoint_test to skip doorbell testing if not advertised by endpoint (Koichiro Den) - Return 0, not remaining timeout, when MHI eDMA ops complete so mhi_ep_ring_add_element() doesn't interpret non-zero as failure (Daniel Hodges) - Remove vntb and ntb duplicate resource teardown that leads to oops when .allow_link() fails or .drop_link() is called (Koichiro Den) - Disable vntb delayed work before clearing BAR mappings and doorbells to avoid oops caused by doing the work after resources have been torn down (Koichiro Den) - Add a way to describe reserved subregions within BARs, e.g., platform-owned fixed register windows, and use it for the RK3588 BAR4 DMA ctrl window (Koichiro Den) - Add BAR_DISABLED for BARs that will never be available to an EPF driver, and change some BAR_RESERVED annotations to BAR_DISABLED (Niklas Cassel) - Add NTB .get_dma_dev() callback for cases where DMA API requires a different device, e.g., vNTB devices (Koichiro Den) - Add reserved region types for MSI-X Table and PBA so Endpoint controllers can them as describe hardware-owned regions in a BAR_RESERVED BAR (Manikanta Maddireddy) - Make Tegra194/234 BAR0 programmable and remove 1MB size limit (Manikanta Maddireddy) - Expose Tegra BAR2 (MSI-X) and BAR4 (DMA) as 64-bit BAR_RESERVED (Manikanta Maddireddy) - Add Tegra194 and Tegra234 device table entries to pci_endpoint_test (Manikanta Maddireddy) - Skip the BAR subrange selftest if there are not enough inbound window resources to run the test (Christian Bruel) New native PCIe controller drivers: - Add DT binding and driver for Andes QiLai SoC PCIe host controller (Randolph Lin) - Add DT binding and driver for ESWIN PCIe Root Complex (Senchuan Zhang) Baikal T-1 PCIe controller driver: - Remove driver since it never quite became usable (Andy Shevchenko) Cadence PCIe controller driver: - Implement byte/word config reads with dword (32-bit) reads because some Cadence controllers don't support sub-dword accesses (Aksh Garg) CIX Sky1 PCIe controller driver: - Add 'power-domains' to DT binding for SCMI power domain (Gary Yang) Freescale i.MX6 PCIe controller driver: - Add i.MX94 and i.MX943 to fsl,imx6q-pcie-ep DT binding (Richard Zhu) - Delay instead of polling for L2/L3 Ready after PME_Turn_off when suspending i.MX6SX because LTSSM registers are inaccessible (Richard Zhu) - Separate PERST# assertion (for resetting endpoints) from core reset (for resetting the RC itself) to prepare for new DTs with PERST# GPIO in per-Root Port nodes (Sherry Sun) - Retain Root Port MSI capability on i.MX7D, i.MX8MM, and i.MX8MQ so MSI from downstream devices will work (Richard Zhu) - Fix i.MX95 reference clock source selection when internal refclk is used (Franz Schnyder) Freescale Layerscape PCIe controller driver: - Allow building as a removable module (Sascha Hauer) MediaTek PCIe Gen3 controller driver: -

Handle 'nvidia,refclk-select' as optional (Vidya Sagar) - Disable direct speed change in Endpoint mode so link speed change is controlled by the host (Vidya Sagar) - Set LTR values before link up to avoid bogus LTR messages with 0 latency (Vidya Sagar) - Allow system suspend when the Endpoint link is down (Vidya Sagar) - Use DWC IP core version, not Tegra custom values, to avoid DWC core version check warnings (Manikanta Maddireddy) - Apply ECRC workaround to devices based on DesignWare 5.00a as well as 4.90a (Manikanta Maddireddy) - Disable PM Substate L1.2 in Endpoint mode to work around Tegra234 erratum (Vidya Sagar) - Delay post-PERST# cleanup until core is powered on to avoid CBB timeout (Manikanta Maddireddy) - Assert CLKREQ# so switches that forward it to their downstream side can bring up those links successfully (Vidya Sagar) - Calibrate pipe to UPHY for Endpoint mode to reset stale PLL state from any previous bad link state (Vidya Sagar) - Remove IRQF_ONESHOT flag from Endpoint interrupt registration so DMA driver and Endpoint controller driver can share the interrupt line (Vidya Sagar) -

Enable doubletap functionality by default on TrackPoint devices that support it. The feature is detected using firmware ID pattern matching (PNP: LEN03xxx) with a deny list of incompatible devices. This provides immediate doubletap functionality without requiring userspace configuration.

2026-03-12Input: psmouse - remove dedicated kpsmoused workqueueDmitry Torokhov
The only user of psmouse_queue_work() and therefore kpsmoused workqueue is psmouse-base itself, when it tries to schedule the resync work. Since resyncing is not going to race with itself we no longer need the dedicated ordered workqueue.

The original code uses flush_workqueue() in psmouse_disconnect() to ensure the completion of both resync_work and dev3_register_work. Given that alps_disconnect() already uses disable_delayed_work_sync() to cancel dev3_register_work, replacing flush_workqueue() with disable_delayed_work_sync(&psmouse->resync_work) is more robust and efficient.

2026-02-21Convert 'alloc_obj' family to use the new default GFP_KERNEL argumentLinus Torvalds
This was done entirely with mindless brute force, using git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' | xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/' to convert the new alloc_obj() users that had a simple GFP_KERNEL argument to just drop that argument. Note that due to the extreme simplicity of the scripting, any slightly more complex cases spread over multiple lines would not be triggered: they definitely exist, but this covers the vast bulk of the cases, and the resulting diff is also then easier to check automatically. For the same reason the 'flex' versions will be done as a separate conversion. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2026-02-21treewide: Replace kmalloc with kmalloc_obj for non-scalar typesKees Cook
This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook <kees@kernel.org>
2026-02-18Input: bcm5974 - recover from failed mode switchLiam Mitchell
Mode switches sent before control response are ignored. This results in an unresponsive trackpad and "bcm5974: bad trackpad package, length: 8" repeated in logs. On receiving unknown 8-byte packets, assume that mode switch was ignored and schedule an asynchronous mode reset. The reset will switch the device to normal mode, wait, then switch back to wellspring mode.

2025-12-18Input: psmouse-smbus - add WQ_UNBOUND to alloc_workqueue userMarco Crivellari
Currently if a user enqueue a work item using schedule_delayed_work() the used wq is "system_wq" (per-cpu wq) while queue_delayed_work() use WORK_CPU_UNBOUND (used when a cpu is not specified). The same applies to schedule_work() that is using system_wq and queue_work(), that makes use again of WORK_CPU_UNBOUND. This lack of consistentcy cannot be addressed without refactoring the API. alloc_workqueue() treats all queues as per-CPU by default, while unbound workqueues must opt-in via WQ_UNBOUND. This default is suboptimal: most workloads benefit from unbound queues, allowing the scheduler to place worker threads where they’re needed and reducing noise when CPUs are isolated. This patch continues the effort to refactor worqueue APIs, which has begun with the change introducing new workqueues and a new alloc_workqueue flag: commit 128ea9f6ccfb ("workqueue: Add system_percpu_wq and system_dfl_wq") commit 930c2ea566af ("workqueue: Add new WQ_PERCPU flag") This specific workload do not benefit from a per-cpu workqueue, so use WQ_UNBOUND on the custom workqueue instead. With the introduction of the WQ_PERCPU flag (equivalent to !WQ_UNBOUND), any alloc_workqueue() caller that doesn’t explicitly specify WQ_UNBOUND must now use WQ_PERCPU. Once migration is complete, WQ_UNBOUND can be removed and unbound will become the implicit default.

2025-12-18Input: synaptics_i2c - replace use of system_wq with system_dfl_wqMarco Crivellari
Currently if a user enqueues a work item using schedule_delayed_work() the used wq is "system_wq" (per-cpu wq) while queue_delayed_work() use WORK_CPU_UNBOUND (used when a cpu is not specified). The same applies to schedule_work() that is using system_wq and queue_work(), that makes use again of WORK_CPU_UNBOUND. This lack of consistency cannot be addressed without refactoring the API.

2025-12-17Input: alps - fix use-after-free bugs caused by dev3_register_workDuoming Zhou
The dev3_register_work delayed work item is initialized within alps_reconnect() and scheduled upon receipt of the first bare PS/2 packet from an external PS/2 device connected to the ALPS touchpad. During device detachment, the original implementation calls flush_workqueue() in psmouse_disconnect() to ensure completion of dev3_register_work. However, the flush_workqueue() in psmouse_disconnect() only blocks and waits for work items that were already queued to the workqueue prior to its invocation. Any work items submitted after flush_workqueue() is called are not included in the set of tasks that the flush operation awaits. This means that after flush_workqueue() has finished executing, the dev3_register_work could still be scheduled. Although the psmouse state is set to PSMOUSE_CMD_MODE in psmouse_disconnect(), the scheduling of dev3_register_work remains unaffected. The race condition can occur as follows: CPU 0 (cleanup path) | CPU 1 (delayed work) psmouse_disconnect() | psmouse_set_state() | flush_workqueue() | alps_report_bare_ps2_packet() alps_disconnect() | psmouse_queue_work() kfree(priv); // FREE | alps_register_bare_ps2_mouse() | priv = container_of(work...); // USE | priv->dev3 // USE Add disable_delayed_work_sync() in alps_disconnect() to ensure that dev3_register_work is properly canceled and prevented from executing after the alps_data structure has been deallocated. This bug is identified by static analysis.

2025-01-20Input: synaptics - fix crash when enabling pass-through portDmitry Torokhov
When enabling a pass-through port an interrupt might come before psmouse driver binds to the pass-through port. However synaptics sub-driver tries to access psmouse instance presumably associated with the pass-through port to figure out if only 1 byte of response or entire protocol packet needs to be forwarded to the pass-through port and may crash if psmouse instance has not been attached to the port yet. Fix the crash by introducing open() and close() methods for the port and check if the port is open before trying to access psmouse instance. Because psmouse calls serio_open() only after attaching psmouse instance to serio port instance this prevents the potential crash.
