Merge branch 'pci/misc' (2024-07-19 10:10:33 -0500)
N.B. 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)

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.
Requires expert knowledge of topology and ACS operation (Vidya Sagar)

Sadhasivam)

Sadhasivam)

on fundamental reset (Manivannan Sadhasivam)

Cassel)

Cassel)

Complex supports ATS (Jean-Philippe Brucker)
