There should be a minor conflict in drivers/pci/pci.c between c9d52fb313d3 ("PCI: Revert the cfg_access_lock lockdep mechanism"), which is already upstream, and 920f6468924f ("PCI: Warn on missing cfg_access_lock during secondary bus reset") which is included in this pull request. ---------------------------------------------------------------- Enumeration: - Define PCIE_RESET_CONFIG_DEVICE_WAIT_MS for the generic 100ms required after reset before config access (Kevin Xie) - Define PCIE_T_RRS_READY_MS for the generic 100ms required after reset before config access (probably should be unified with PCIE_RESET_CONFIG_DEVICE_WAIT_MS) (Damien Le Moal) Resource management: - Rename find_resource() to find_resource_space() to be more descriptive (Ilpo Järvinen) - Export find_resource_space() for use by PCI core, which needs to learn whether there is available space for a bridge window (Ilpo Järvinen) - Prevent double counting of resources so window size doesn't grow on each remove/rescan cycle (Ilpo Järvinen) - Relax bridge window sizing algorithm so a device doesn't break simply because it was removed and rescanned (Ilpo Järvinen) - Evaluate the ACPI PRESERVE_BOOT_CONFIG _DSM in pci_register_host_bridge() (not acpi_pci_root_create()) so we can unify it with similar DT functionality (Vidya Sagar) - Extend use of DT "linux,pci-probe-only" property so it works per-host bridge as well as globally (Vidya Sagar) - Unify support for ACPI PRESERVE_BOOT_CONFIG _DSM and the DT "linux,pci-probe-only" property in pci_preserve_config() (Vidya Sagar) Driver binding: - Add devres infrastructure for managed request and map of partial BAR resources (Philipp Stanner) - Deprecate pcim_iomap_table() because uses like "pcim_iomap_table()[0]" have no good way to return errors (Philipp Stanner) - Add an always-managed pcim_request_region() for use instead of pci_request_region() and similar, which are sometimes managed depending on whether pcim_enable_device() has been called previously (Philipp Stanner) - Reimplement pcim_set_mwi() so it doesn't need to keep store MWI state (Philipp Stanner) - Add pcim_intx() for use instead of pci_intx(), which is sometimes managed depending on whether pcim_enable_device() has been called previously (Philipp Stanner) - Add managed pcim_iomap_range() to allow mapping of a partial BAR (Philipp Stanner) - Fix a devres mapping leak in drm/vboxvideo (Philipp Stanner) Error handling: - Add missing bridge locking in device reset path and add a warning for other possible lock issues (Dan Williams) - Fix use-after-free on concurrent DPC and hot-removal (Lukas Wunner) Power management: - Disable AER and DPC during suspend to avoid spurious wakeups if they share an interrupt with PME (Kai-Heng Feng) PCIe native device hotplug: - Detect if a device was removed or replaced during system sleep so we don't assume a new device is the one that used to be there (Lukas Wunner) Virtualization: - Add an ACS quirk for Broadcom BCM5760X multi-function NIC; it prevents transactions between functions even though it doesn't advertise ACS, so the functions can be attached individually via VFIO (Ajit Khaparde) Peer-to-peer DMA: - Add a "pci=config_acs=" kernel command-line parameter to relax default ACS settings to enable additional peer-to-peer configurations.
