Documentation/driver-api: fixed spelling mistakes
Fixed some spelling mistakes identified by misspell tool. The example code in Documentation/driver-api/nvdimm/nvdimm.rst contained a misspelled identifier (paramaters instead of parameters).

driver core: add a faux bus for use when a simple device/bus is needed
Many drivers abuse the platform driver/bus system as it provides a simple way to create and bind a device to a driver-specific set of probe/release functions. Instead of doing that, and wasting all of the memory associated with a platform device, here is a "faux" bus that can be used instead.

This happens because the only async polling without interrupts that
iaa_crypto currently implements is with the 'sync' mode. With 'async',
iaa_crypto calls to compress/decompress submit the descriptor and return
-EINPROGRESS, without any mechanism in the driver to poll for
completions. Hence callers such as test_acomp() in crypto/testmgr.c or
zswap, that wrap the calls to crypto_acomp_compress() and
crypto_acomp_decompress() in synchronous wrappers, will block
indefinitely. Even before zswap can notice this problem, the crypto
testmgr.c's test_acomp() will fail and prevent registration of
"deflate-iaa" as a valid crypto acomp algorithm, thereby disallowing the
use of "deflate-iaa" as a zswap compress (zswap will fall-back to the
default compressor in this case).
To fix this issue, this patch modifies the iaa_crypto sync_mode set
function to treat 'async' equivalent to 'sync', so that the correct and
only supported driver async polling without interrupts implementation is
enabled, and zswap can use 'deflate-iaa' as the compressor.
Hence, with this patch, this is what will happen:
echo async > /sys/bus/dsa/drivers/crypto/sync_mode
cat /sys/bus/dsa/drivers/crypto/sync_mode
sync
There are no crypto/testmgr.c test_acomp() errors, no call traces and zswap
can use 'deflate-iaa' without any errors. The iaa_crypto documentation has
also been updated to mention this caveat with 'async' and what to expect
with this fix.
True iaa_crypto async polling without interrupts is enabled in patch
"crypto: iaa - Implement batch_compress(), batch_decompress() API in
iaa_crypto." [1] which is under review as part of the "zswap IAA compress
batching" patch-series [2]. Until this is merged, we would appreciate it if
this current patch can be considered for a hotfix.

Driver core changes for 6.13-rc1
Here is a small set of driver core changes for 6.13-rc1. Nothing major for this merge cycle, except for the 2 simple merge conflicts are here just to make life interesting. Included in here are: - sysfs core changes and preparations for more sysfs api cleanups that can come through all driver trees after -rc1 is out - fw_devlink fixes based on many reports and debugging sessions - list_for_each_reverse() removal, no one was using it! - last-minute seq_printf() format string bug found and fixed in many drivers all at once. - minor bugfixes and changes full details in the shortlog As mentioned above, there is 2 merge conflicts with your tree, one is where the file is removed (easy enough to resolve), the second is a build time error, that has been found in linux-next and the fix can be seen here: https://lore.kernel.org/r/20241107212645.41252436@canb.auug.org.au Other than that, the changes here have been in linux-next with no other reported issues.

Make pci_stop_dev() and pci_destroy_dev() safe so concurrent callers can't stop a device multiple times, even as we migrate from the global pci_rescan_remove_lock to finer-grained locking (Keith Busch) - Improve pci_walk_bus() implementation by making it recursive and moving locking up to avoid need for a 'locked' parameter (Keith Busch) - Unexport pci_walk_bus_locked(), which is only used internally by the PCI core (Keith Busch) - Detect some Thunderbolt chips that are built-in and hence 'trustworthy' by a heuristic since the 'ExternalFacingPort' and 'usb4-host-interface' ACPI properties are not quite enough (Esther Shimanovich) Resource management: - Use PCI bus addresses (not CPU addresses) in 'ranges' properties when building dynamic DT nodes so systems where PCI and CPU addresses differ work correctly (Andrea della Porta) - Tidy resource sizing and assignment with helpers to reduce redundancy (Ilpo Järvinen) - Improve pdev_sort_resources() 'bogus alignment' warning to be more specific (Ilpo Järvinen) Driver binding: - Convert driver .remove_new() callbacks to .remove() again to finish the conversion from returning 'int' to being 'void' (Sergio Paracuellos) - Export pcim_request_all_regions(), a managed interface to request all BARs (Philipp Stanner) - Replace pcim_iomap_regions_request_all() with pcim_request_all_regions(), and pcim_iomap_table()[n] with pcim_iomap(n), in the following drivers: ahci, crypto qat, crypto octeontx2, intel_th, iwlwifi, ntb idt, serial rp2, ALSA korg1212 (Philipp Stanner) - Remove the now unused pcim_iomap_regions_request_all() (Philipp Stanner) - Export pcim_iounmap_region(), a managed interface to unmap and release a PCI BAR (Philipp Stanner) - Replace pcim_iomap_regions(mask) with pcim_iomap_region(n), and pcim_iounmap_regions(mask) with pcim_iounmap_region(n), in the following drivers: fpga dfl-pci, block mtip32xx, gpio-merrifield, cavium (Philipp Stanner) Error handling: - Add sysfs 'reset_subordinate' to reset the entire hierarchy below a bridge; previously Secondary Bus Reset could only be used when there was a single device below a bridge (Keith Busch) - Warn if we reset a running device where the driver didn't register pci_error_handlers notification callbacks (Keith Busch) ASPM: - Disable ASPM L1 before touching L1 PM Substates to follow the spec closer and avoid a CPU load timeout on some platforms (Ajay Agarwal) - Set devices below Intel VMD to D0 before enabling ASPM L1 Substates as required per spec for all L1 Substates changes (Jian-Hong Pan) Power management: - Enable starfive controller runtime PM before probing host bridge (Mayank Rana) - Enable runtime power management for host bridges (Krishna chaitanya chundru) Power control: - Use of_platform_device_create() instead of of_platform_populate() to create pwrctl platform devices so we can control it based on the child nodes (Manivannan Sadhasivam) - Create pwrctrl platform devices only if there's a relevant power supply property (Manivannan Sadhasivam) - Add device link from the pwrctl supplier to the PCI dev to ensure pwrctl drivers are probed before the PCI dev driver; this avoids a race where pwrctl could change device power state while the PCI driver was active (Manivannan Sadhasivam) - Find pwrctl device for removal with of_find_device_by_node() instead of searching all children of the parent (Manivannan Sadhasivam) - Rename 'pwrctl' to 'pwrctrl' to match new bandwidth controller ('bwctrl') and hotplug files (Bjorn Helgaas) Bandwidth control: - Add read/modify/write locking for Link Control 2, which is used to manage Link speed (Ilpo Järvinen) - Extract Link Bandwidth Management Status check into pcie_lbms_seen(), where it can be shared between the bandwidth controller and quirks that use it to help retrain failed links (Ilpo Järvinen) - Re-add Link Bandwidth notification support with updates to address the reasons it was previously reverted (Alexandru Gagniuc, Ilpo Järvinen) - Add pcie_set_target_speed() and related functionality so drivers can manage PCIe Link speed based on thermal or other constraints (Ilpo Järvinen) - Add a thermal cooling driver to throttle PCIe Links via the existing thermal management framework (Ilpo Järvinen) - Add a userspace selftest for the PCIe bandwidth controller (Ilpo Järvinen) PCI device hotplug: - Add hotplug controller driver for Marvell OCTEON multi-function device where function 0 has a management console interface to enable/disable and provision various personalities for the other functions (Shijith Thotton) - Retain a reference to the pci_bus for the lifetime of a pci_slot to avoid a use-after-free when the thunderbolt driver resets USB4 host routers on boot, causing hotplug remove/add of downstream docks or other devices (Lukas Wunner) - Remove unused cpcihp struct cpci_hp_controller_ops.hardware_test (Guilherme Giacomo Simoes) - Remove unused cpqphp struct ctrl_dbg.ctrl (Christophe JAILLET) - Use pci_bus_read_dev_vendor_id() instead of hand-coded presence detection in cpqphp (Ilpo Järvinen) - Simplify cpqphp enumeration, which is already simple-minded and doesn't handle devices below hot-added bridges (Ilpo Järvinen) Virtualization: - Add ACS quirk for Wangxun FF5xxx NICs, which don't advertise an ACS capability but do isolate functions as though PCI_ACS_RR and PCI_ACS_CR were set, so the functions can be in independent IOMMU groups (Mengyuan Lou) TLP Processing Hints (TPH): - Add and document TLP Processing Hints (TPH) support so drivers can enable and disable TPH and the kernel can save/restore TPH configuration (Wei Huang) - Add TPH Steering Tag support so drivers can retrieve Steering Tag values associated with specific CPUs via an ACPI _DSM to improve performance by directing DMA writes closer to their consumers (Wei Huang) Data Object Exchange (DOE): - Wait up to 1 second for DOE Busy bit to clear before writing a request to the mailbox to avoid failures if the mailbox is still busy from a previous transfer (Gregory Price) Endpoint framework: - Skip attempts to allocate from endpoint controller memory window if the requested size is larger than the window (Damien Le Moal) - Add and document pci_epc_mem_map() and pci_epc_mem_unmap() to handle controller-specific size and alignment constraints, and add test cases to the endpoint test driver (Damien Le Moal) - Implement dwc pci_epc_ops.align_addr() so pci_epc_mem_map() can observe DWC-specific alignment requirements (Damien Le Moal) - Synchronously cancel command handler work in endpoint test before cleaning up DMA and BARs (Damien Le Moal) - Respect endpoint page size in dw_pcie_ep_align_addr() (Niklas Cassel) - Use dw_pcie_ep_align_addr() in dw_pcie_ep_raise_msi_irq() and dw_pcie_ep_raise_msix_irq() instead of open coding the equivalent (Niklas Cassel) - Avoid NULL dereference if Modem Host Interface Endpoint lacks 'mmio' DT property (Zhongqiu Han) - Release PCI domain ID of Endpoint controller parent (not controller itself) and before unregistering the controller, to avoid use-after-free (Zijun Hu) - Clear secondary (not primary) EPC in pci_epc_remove_epf() when removing the secondary controller associated with an NTB (Zijun Hu) Cadence PCIe controller driver: - Lower severity of 'phy-names' message (Bartosz Wawrzyniak) Freescale i.MX6 PCIe controller driver: - Fix suspend/resume support on i.MX6QDL, which has a hardware erratum that prevents use of L2 (Stefan Eichenberger) Intel VMD host bridge driver: - Add 0xb60b and 0xb06f Device IDs for client SKUs (Nirmal Patel) MediaTek PCIe Gen3 controller driver: - Update mediatek-gen3 DT binding to require the exact number of clocks for each SoC (Fei Shao) - Add support for DT 'max-link-speed' and 'num-lanes' properties to restrict the link speed and width (AngeloGioacchino Del Regno) Microchip PolarFlare PCIe controller driver: - Add DT and driver support for using either of the two PolarFire Root Ports (Conor Dooley) NVIDIA Tegra194 PCIe controller driver: - Move endpoint controller cleanups that depend on refclk from the host to the notifier that tells us the host has deasserted PERST#, when refclk should be valid (Manivannan Sadhasivam) Qualcomm PCIe controller driver: - Add qcom SAR2130P DT binding with an additional clock (Dmitry Baryshkov) - Enable MSI interrupts if 'global' IRQ is supported, since a previous commit unintentionally masked them (Manivannan Sadhasivam) - Move endpoint controller cleanups that depend on refclk from the host to the notifier that tells us the host has deasserted PERST#, when refclk should be valid (Manivannan Sadhasivam) - Add DT binding and driver support for IPQ9574, with Synopsys IP v5.80a and Qcom IP 1.27.0 (devi priya) - Move the OPP "operating-points-v2" table from the qcom,pcie-sm8450.yaml DT binding to qcom,pcie-common.yaml, where it can be used by other Qcom platforms (Qiang Yu) - Add 'global' SPI interrupt for events like link-up, link-down to qcom,pcie-x1e80100 DT binding so we can start enumeration when the link comes up (Qiang Yu) - Disable ASPM L0s for qcom,pcie-x1e80100 since the PHY is not tuned to support this (Qiang Yu) - Add ops_1_21_0 for SC8280X family SoC, which doesn't use the 'iommu-map' DT property and doesn't need BDF-to-SID translation (Qiang Yu) Rockchip PCIe controller driver: - Define ROCKCHIP_PCIE_AT_SIZE_ALIGN to replace magic 256 endpoint .align value (Damien Le Moal) - When unmapping an endpoint window, compute the region index instead of searching for it, and verify that the address was mapped (Damien Le Moal) - When mapping an endpoint window, verify that the address hasn't been mapped already (Damien Le Moal) - Implement pci_epc_ops.align_addr() for rockchip-ep (Damien Le Moal) - Fix MSI IRQ data mapping to observe the alignment constraint, which fixes intermittent page faults in memcpy_toio() and memcpy_fromio() (Damien Le Moal) - Rename rockchip_pcie_parse_ep_dt() to rockchip_pcie_ep_get_resources() for consistency with similar DT interfaces (Damien Le Moal) - Skip the unnecessary link train in rockchip_pcie_ep_probe() and do it only in the endpoint start operation (Damien Le Moal) - Implement pci_epc_ops.stop_link() to disable link training and controller configuration (Damien Le Moal) - Attempt link training at 5 GT/s when both partners support it (Damien Le Moal) - Add a handler for PERST# signal so we can detect host-initiated resets and start link training after PERST# is deasserted (Damien Le Moal) Synopsys DesignWare PCIe controller driver: - Clear outbound address on unmap so dw_pcie_find_index() won't match an ATU index that was already unmapped (Damien Le Moal) - Use of_property_present() instead of of_property_read_bool() when testing for presence of non-boolean DT properties (Rob Herring) - Advertise 1MB size if endpoint supports Resizable BARs, which was inadvertently lost in v6.11 (Niklas Cassel) TI J721E PCIe driver: - Add PCIe support for J722S SoC (Siddharth Vadapalli) - Delay PCIE_T_PVPERL_MS (100 ms), not just PCIE_T_PERST_CLK_US (100 us), before deasserting PERST# to ensure power and refclk are stable (Siddharth Vadapalli) TI Keystone PCIe controller driver: - Set the 'ti,keystone-pcie' mode so v3.65a devices work in Root Complex mode (Kishon Vijay Abraham I) - Try to avoid unrecoverable SError for attempts to issue config transactions when the link is down; this is racy but the best we can do (Kishon Vijay Abraham I) Miscellaneous: -

firewire updates for v6.12
The batch of changes includes the followwing: - Replacing tasklet with usual workqueue for isochronous context - Replacing IDR with XArray - Utilizing guard macro where possible - Printing deprecation warning when enabling debug parameter of firewire-ohci module Additionally, it includes a single patch for sound subsystem which the subsystem maintainer acked: - Switching to nonatomic PCM operation In FireWire subsystem, tasklet has been used as the bottom half of 1394 OHCi hardIRQ so long. In the recent kernel updates, BH workqueue has been available, and some developers have proposed replacing tasklet with BH workqueue. While it is fortunate that developers are still considering the legacy subsystem, a simple replacement is not necessarily suitable. As a first step towards dropping tasklet, I've investigated the feasibility for 1394 OHCI isochronous context, and concluded that usual workqueue is available. In the context, the batch of packets is processed in the specific queue, thus the timing jitter caused by task scheduling is not so critical. Additionally, DMA transmission can be scheduled per-packet basis, therefore the context can be sleep between the operation of transmissions. Furthermore, in-kernel protocol implementation involves some CPU-bound tasks, which can sometimes consumes CPU time so long. These characteristics suggest that usual workqueue is suitable, through BH workqueues are not. The replacement with usual workqueue allows unit drivers to process the content of packets in non-atomic context. It brings some reliefs to some drivers in sound subsystem that spin-lock is not mandatory anymore during isochronous packet processing. -----BEGIN PGP SIGNATURE----- iHUEABYKAB0WIQQE66IEYNDXNBPeGKSsLtaWM8LwEwUCZu41yQAKCRCsLtaWM8Lw E4Y1AP43vZatH202NNMnbkLSW9axmHe6VHWEwDSsJT80vTbBNAD/WYV62EoQzlk1 1lzdts11SSqYPhj6tJDuRgqULlNAows= =7VMx -----END PGP SIGNATURE----- Merge tag 'firewire-updates-6.12' of git://git.kernel.org/pub/scm/linux/kernel/git/ieee1394/linux1394 Pull firewire updates from Takashi Sakamoto: "In the FireWire subsystem, tasklets have been used as the bottom half of 1394 OHCi hardIRQ.

firewire: core: expose kernel API to schedule work item to process isochronous context
In packet-per-buffer mode for isochronous context of 1394 OHCI, software can schedule hardIRQ to the buffer in which the content of isochronous packet is processed. The actual behaviour is different between isochronous receive (IR) and transmit (IT) contexts in respect to isochronous cycle in which the hardIRQ occurs. In IR context, the hardIRQ occurs when the buffer is filled actually by the content of received packet. If there are any isochronous cycles in which the packet transmission is skipped, it is postponed to generate the hardIRQ in respect to the isochronous cycle. In IT context, software can schedule the content of packet every isochronous cycle including skipping, therefore the hardIRQ occurs in the isochronous cycle to which the software scheduled. ALSA firewire stack uses the packet-per-buffer mode for both IR/IT contexts. To process time stamp per packet (or per sample in some cases) steadily for media clock recovery against unexpected transmission skips, it uses an IT context to operate all of isochronous contexts by calls of fw_iso_context_flush_completions() in the bottom-half of hardIRQ for the IT context. Although it looks well to handle all of isochronous contexts in a single bottom-half context, it relatively takes longer time. In the future code integration (not yet), it is possible to apply parallelism method to process these context. In the case, it is useful to allow unit drivers to schedule work items to process these isochronous contexts. As a preparation, this commit exposes fw_iso_context_schedule_flush_completions() as a kernel API available by unit drivers. It is renamed from fw_iso_context_queue_work() since it is a counter part of fw_iso_context_flush_completions().
