2025-11-24treewide: Drop pci_save_state() after pci_restore_state()Lukas Wunner
In 2009, commit c82f63e411f1 ("PCI: check saved state before restore") changed the behavior of pci_restore_state() such that it became necessary to call pci_save_state() afterwards, lest recovery from subsequent PCI errors fails. The commit has just been reverted and so all the pci_save_state() after pci_restore_state() calls that have accumulated in the tree are now superfluous. Drop them. Two drivers chose a different approach to achieve the same result: drivers/scsi/ipr.c and drivers/net/ethernet/intel/e1000e/netdev.c set the pci_dev's "state_saved" flag to true before calling pci_restore_state(). Drop this as well.

2025-11-12Merge patch series "replace old wq(s), added WQ_PERCPU to alloc_workqueue"Martin K. Petersen
Marco Crivellari <marco.crivellari@suse.com> says: Hi, === Current situation: problems === Let's consider a nohz_full system with isolated CPUs: wq_unbound_cpumask is set to the housekeeping CPUs, for !WQ_UNBOUND the local CPU is selected. This leads to different scenarios if a work item is scheduled on an isolated CPU where "delay" value is 0 or greater then 0: schedule_delayed_work(, 0); This will be handled by __queue_work() that will queue the work item on the current local (isolated) CPU, while: schedule_delayed_work(, 1); Will move the timer on an housekeeping CPU, and schedule the work there. 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 consistency cannot be addressed without refactoring the API. === Recent changes to the WQ API === The following, address the recent changes in the Workqueue API: - commit 128ea9f6ccfb ("workqueue: Add system_percpu_wq and system_dfl_wq") - commit 930c2ea566af ("workqueue: Add new WQ_PERCPU flag") The old workqueues will be removed in a future release cycle. === Introduced Changes by this series === 1) [P 1] Replace uses of system_wq and system_unbound_wq system_unbound_wq is to be used when locality is not required. Because of that, system_unbound_wq has been replaced with system_dfl_wq, to make clear it should be used when locality is not required. 2) [P 2-3-4] WQ_PERCPU added to alloc_workqueue() This change adds a new WQ_PERCPU flag to explicitly request alloc_workqueue() to be per-cpu when WQ_UNBOUND has not been specified.

2025-11-12scsi: lpfc: WQ_PERCPU added to alloc_workqueue() usersMarco 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 change adds a new WQ_PERCPU flag to explicitly request alloc_workqueue() to be per-cpu when WQ_UNBOUND has not been specified. 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") 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.

2025-11-08scsi: lpfc: Modify kref handling for Fabric Controller ndlpsJustin Tee
Currently, there is a kref put in the lpfc_cleanup() routine that takes care of outstanding references on fabric controller ndlps in UNUSED state. While typically there is a state change from UNUSED -> REGLOGIN when the ndlp successfully logs into the fabric, there may be cases when FLOGI is unsuccessful and the ndlp will remain in UNUSED state without a registered rpi, yet the ndlp incorrectly has a kref count of one. To address this, handling of Fabric Controller ndlps are moved into the routines: lpfc_issue_els_scr(), lpfc_issue_els_rdf(), lpfc_cmpl_els_disc_cmd(). In both lpfc_issue_els_scr() and lpfc_issue_els_rdf(), if there does not exist a previously created fabric controller ndlp, an ndlp will be created. Otherwise, we can reuse the pre-existing ndlp object. In lpfc_cmpl_els_disc_cmd(), if the SCR or RDF are not successfully issued, the initial reference on the ndlp that is not registered with upper layers will be decremented with a kref_put().

Implement pci_find_capability(), pci_find_ext_capability(), and dwc, dwc endpoint, and cadence capability search interfaces with them (Hans Zhang) - Leave parent unit address 0 in 'interrupt-map' so that when we build devicetree nodes to describe PCI functions that contain multiple peripherals, we can build this property even when interrupt controllers lack 'reg' properties (Lorenzo Pieralisi) - Add a Xeon 6 quirk to disable Extended Tags and limit Max Read Request Size to 128B to avoid a performance issue (Ilpo Järvinen) - Add sysfs 'serial_number' file to expose the Device Serial Number (Matthew Wood) - Fix pci_acpi_preserve_config() memory leak (Nirmoy Das) Resource management: - Align m68k pcibios_enable_device() with other arches (Ilpo Järvinen) - Remove sparc pcibios_enable_device() implementations that don't do anything beyond what pci_enable_resources() does (Ilpo Järvinen) - Remove mips pcibios_enable_resources() and use pci_enable_resources() instead (Ilpo Järvinen) - Clean up bridge window sizing and assignment (Ilpo Järvinen), including: - Leave non-claimed bridge windows disabled - Enable bridges even if a window wasn't assigned because not all windows are required by downstream devices - Preserve bridge window type when releasing the resource, since the type is needed for reassignment - Consolidate selection of bridge windows into two new interfaces, pbus_select_window() and pbus_select_window_for_type(), so this is done consistently - Compute bridge window start and end earlier to avoid logging stale information MSI: - Add quirk to disable MSI on RDC PCI to PCIe bridges (Marcos Del Sol Vives) Error handling: - Align AER with EEH by allowing drivers to request a Bus Reset on Non-Fatal Errors (in addition to the reset on Fatal Errors that we already do) (Lukas Wunner) - If error recovery fails, emit FAILED_RECOVERY uevents for the devices, not for the bridge leading to them. This makes them correspond to BEGIN_RECOVERY uevents (Lukas Wunner) - Align AER with EEH by calling err_handler.error_detected() callbacks to notify drivers if error recovery fails (Lukas Wunner) - Align AER with EEH by restoring device error_state to pci_channel_io_normal before the err_handler.slot_reset() callback. This is earlier than before the err_handler.resume() callback (Lukas Wunner) - Emit a BEGIN_RECOVERY uevent when driver's err_handler.error_detected() requests a reset, as well as when it says recovery is complete or can be done without a reset (Niklas Schnelle) - Align s390 with AER and EEH by emitting uevents during error recovery (Niklas Schnelle) - Align EEH with AER and s390 by emitting BEGIN_RECOVERY, SUCCESSFUL_RECOVERY, or FAILED_RECOVERY uevents depending on the result of err_handler.error_detected() (Niklas Schnelle) - Fix a NULL pointer dereference in aer_ratelimit() when ACPI GHES error information identifies a device without an AER Capability (Breno Leitao) - Update error decoding and TLP Log printing for new errors in current PCIe base spec (Lukas Wunner) - Update error recovery documentation to match the current code and use consistent nomenclature (Lukas Wunner) ASPM: - Enable all ClockPM and ASPM states for devicetree platforms, since there's typically no firmware that enables ASPM This is a risky change that may uncover hardware or configuration defects at boot-time rather than when users enable ASPM via sysfs later. Booting with "pcie_aspm=off" prevents this enabling (Manivannan Sadhasivam) - Remove the qcom code that enabled ASPM (Manivannan Sadhasivam) Power management: - If a device has already been disconnected, e.g., by a hotplug removal, don't bother trying to resume it to D0 when detaching the driver. This avoids annoying "Unable to change power state from D3cold to D0" messages (Mario Limonciello) - Ensure devices are powered up before config reads for 'max_link_width', 'current_link_speed', 'current_link_width', 'secondary_bus_number', and 'subordinate_bus_number' sysfs files. This prevents using invalid data (~0) in drivers or lspci and, depending on how the PCIe controller reports errors, may avoid error interrupts or crashes (Brian Norris) Virtualization: - Add rescan/remove locking when enabling/disabling SR-IOV, which avoids list corruption on s390, where disabling SR-IOV also generates hotplug events (Niklas Schnelle) Peer-to-peer DMA: - Free struct p2p_pgmap, not a member within it, in the pci_p2pdma_add_resource() error path (Sungho Kim) Endpoint framework: - Document sysfs interface for BAR assignment of vNTB endpoint functions (Jerome Brunet) -

Restore inbound translation when disabling doorbell so the endpoint doorbell test case can be run more than once (Niklas Cassel) - Avoid a NULL pointer dereference when releasing DMA channels in endpoint DMA test case (Shin'ichiro Kawasaki) - Convert tegra194 interrupt number to MSI vector to fix endpoint Kselftest MSI_TEST test case (Niklas Cassel) - Reset tegra194 BARs when running in endpoint mode so the BAR tests don't overwrite the ATU settings in BAR4 (Niklas Cassel) -

Add driver support for PERST# being described in a Root Port stanza, falling back to the host bridge if not found there (Sai Krishna Musham) Freescale i.MX6 PCIe controller driver: - Enable the 3.3V Vaux supply if available so devices can request wakeup with either Beacon or WAKE# (Richard Zhu) MediaTek PCIe Gen3 controller driver: - Add optional sys clock ready time setting to avoid sys_clk_rdy signal glitching in MT6991 and MT8196 (AngeloGioacchino Del Regno) - Add DT binding and driver support for MT6991 and MT8196 (AngeloGioacchino Del Regno) NVIDIA Tegra PCIe controller driver: - When asserting PERST#, disable the controller instead of mistakenly disabling the PLL twice (Nagarjuna Kristam) - Convert struct tegra_msi mask_lock to raw spinlock to avoid a lock nesting error (Marek Vasut) Qualcomm PCIe controller driver: - Select PCI Power Control Slot driver so slot voltage rails can be turned on/off if described in Root Port devicetree node (Qiang Yu) - Parse only PCI bridge child nodes in devicetree, skipping unrelated nodes such as OPP (Operating Performance Points), which caused probe failures (Krishna Chaitanya Chundru) - Add 8.0 GT/s and 32.0 GT/s equalization settings (Ziyue Zhang) - Consolidate Root Port 'phy' and 'reset' properties in struct qcom_pcie_port, regardless of whether we got them from the Root Port node or the host bridge node (Manivannan Sadhasivam) - Fetch and map the ELBI register space in the DWC core rather than in each driver individually (Krishna Chaitanya Chundru) - Enable ECAM mechanism in DWC core by setting up iATU with 'CFG Shift Feature' and use this in the qcom driver (Krishna Chaitanya Chundru) - Add SM8750 compatible to qcom,pcie-sm8550.yaml (Krishna Chaitanya Chundru) - Update qcom,pcie-x1e80100.yaml to allow fifth PCIe host on Qualcomm Glymur, which is compatible with X1E80100 but doesn't have the cnoc_sf_axi clock (Qiang Yu) Renesas R-Car PCIe controller driver: -

Fix inverted PHY initialization check, which sometimes led to timeouts and failure to start the controller (Marek Vasut) - Pass the correct IRQ domain to generic_handle_domain_irq() to fix a regression when converting to msi_create_parent_irq_domain() (Claudiu Beznea) -

2025-08-13PCI/ERR: Remove remnants of .link_reset() callbackLukas Wunner
Back in 2017, commit 2fd260f03b6a ("PCI/AER: Remove unused .link_reset() callback") removed .link_reset() from struct pci_error_handlers, but left a few code comments behind which still mention it. Remove them. The code comments in the SolarFlare Ethernet drivers point out that no .mmio_enabled() callback is needed because the driver's .error_detected() callback always returns PCI_ERS_RESULT_NEED_RESET, which causes pcie_do_recovery() to skip .mmio_enabled(). That's not quite correct because efx_io_error_detected() does return PCI_ERS_RESULT_RECOVERED under certain conditions and then .mmio_enabled() would indeed be called if it were implemented.

During initialization, the driver allocates wq->pring in lpfc_wq_create and lpfc_sli4_queue_unset() is the only place where kfree(wq->pring) is called. There is a possible memory leak in lpfc_sli_brdrestart_s4() (restart) and lpfc_pci_remove_one_s4() (rmmod) paths because there are no calls to lpfc_sli4_queue_unset() to kfree() the wq->pring. Fix by inserting a call to lpfc_sli4_queue_unset() in lpfc_sli_brdrestart_s4() and lpfc_sli4_hba_unset() routines. Also, add a check for the SLI_ACTIVE flag before issuing the Q_DESTROY mailbox command. If not set, then the mailbox command will obviously fail. In such cases, skip issuing the mailbox command and only execute the driver resource clean up portions of the lpfc_*q_destroy routines.

In LPFC_MBOXQ_t, the ctx_buf ptr shouldn't be defined as a generic void *ptr. It is named ctx_buf and it should only be used as an lpfc_dmabuf *ptr. Due to the void* declaration, there have been abuses of ctx_buf for things not related to lpfc_dmabuf. So, set the ptr type for *ctx_buf as lpfc_dmabuf. Remove all type casts on ctx_buf because it is no longer a void *ptr. Convert the abuse of ctx_buf for something not related to lpfc_dmabuf to use the void *context3 ptr. A particular abuse of the ctx_buf warranted a new void *ext_buf ptr. However, the usage of this new void *ext_buf is not generic.

Although vport memory region is owned by shost->hostdata, it is driver private memory and an explicit fc_nodes list lock for fc_nodes list mutations is more appropriate than locking the entire shost.

2024-02-05scsi: lpfc: Change nlp state statistic counters into atomic_tJustin Tee
There is no reason to use the shost_lock to synchronize an LLDD statistics counter. Convert all the nlp state statistic counters into atomic_t. Corresponding zeroing, increments, and reads are converted to atomic versions.

2024-02-05scsi: lpfc: Move handling of reset congestion statistics eventsJustin Tee
The ACQE notification event to reset congestion statistics should be moved into the specific lpfc_sli4_async_sli_evt() routine instead of being processed from the generic lpfc_sli4_async_event_proc() routine.

2023-11-15scsi: lpfc: Fix possible file string name overflow when updating firmwareJustin Tee
Because file_name and phba->ModelName are both declared a size 80 bytes, the extra ".grp" file extension could cause an overflow into file_name. Define a ELX_FW_NAME_SIZE macro with value 84. 84 incorporates the 4 extra characters from ".grp". file_name is changed to be declared as a char and initialized to zeros i.e. null chars.
