Linux 6.5-rc1 (2023-07-09 13:53:13 -0700)
are available in the Git repository at:

Merge branch 'pci/misc' (2023-08-29 11:03:57 -0500)
----------------------------------------------------------------
Enumeration:
- Add locking to read/modify/write PCIe Capability Register accessors for
Link Control and Root Control
- Use pci_dev_id() when possible instead of manually composing ID from
dev->bus->number and dev->devfn
Resource management:
- Move prototypes for __weak sysfs resource files to linux/pci.h to fix
"no previous prototype" warnings
- Make more I/O port accesses depend on HAS_IOPORT
- Use devm_platform_get_and_ioremap_resource() instead of open-coding
platform_get_resource() followed by devm_ioremap_resource()
Power management:
- Ensure devices are powered up while accessing VPD
- If device is powered-up, keep it that way while polling for PME
- Only read PCI_PM_CTRL register when available, to avoid reading the
wrong register and corrupting dev->current_state
Virtualization:
- Avoid Secondary Bus Reset on NVIDIA T4 GPUs
Error handling:
- Remove unused pci_disable_pcie_error_reporting()
- Unexport pci_enable_pcie_error_reporting(), used only by aer.c
- Unexport pcie_port_bus_type, used only by PCI core
VGA:
- Simplify and clean up typos in VGA arbiter
Apple PCIe controller driver:
- Initialize pcie->nvecs (number of available MSIs) before use
Broadcom iProc PCIe controller driver:
- Use of_property_read_bool() instead of low-level accessors for boolean
properties
Broadcom STB PCIe controller driver:
- Assert PERST# when probing BCM2711 because some bootloaders don't do it
Freescale i.MX6 PCIe controller driver:
- Add .host_deinit() callback so we can clean up things like regulators
on probe failure or driver unload
Freescale Layerscape PCIe controller driver:
- Add support for link-down notification so the endpoint driver can
process LINK_DOWN events
- Add suspend/resume support, including manual PME_Turn_off/PME_TO_Ack
handshake
- Save Link Capabilities during probe so they can be restored when
handling a link-up event, since the controller loses the Link Width and
Link Speed values during reset
Intel VMD host bridge driver:
- Fix disable of bridge windows during domain reset; previously we
cleared the base/limit registers, which actually left the windows
enabled
Marvell MVEBU PCIe controller driver:
- Remove unused busn member
Microchip PolarFlare PCIe controller driver:
- Fix interrupt bit definitions so the SEC and DED interrupt handlers
work correctly
- Make driver buildable as a module
- Read FPGA MSI configuration parameters from hardware instead of
hard-coding them
Microsoft Hyper-V host bridge driver:
- To avoid a NULL pointer dereference, skip MSI restore after hibernate
if MSI/MSI-X hasn't been enabled
NVIDIA Tegra194 PCIe controller driver:
- Revert "PCI: tegra194: Enable support for 256 Byte payload" because
Linux doesn't know how to reduce MPS from to 256 to 128 bytes for
Endpoints below a Switch (because other devices below the Switch might
already be operating), which leads to Malformed TLP errors
Qualcomm PCIe controller driver:
- Add DT and driver support for interconnect bandwidth voting for
"pcie-mem" and "cpu-pcie" interconnects
- Fix broken SDX65 "compatible" DT property
- Configure controller so MHI bus master clock will be switched off while
in ASPM L1.x states
- Use alignment restriction from EPF core in EPF MHI driver
- Add Endpoint eDMA support
- Add MHI eDMA support
- Add Snapdragon SM8450 support to the EPF MHI driversupport
- Add MHI eDMA support
- Add Snapdragon SM8450 support to the EPF MHI driversupport
- Add MHI eDMA support
- Add Snapdragon SM8450 support to the EPF MHI driversupport
- Add MHI eDMA support
- Add Snapdragon SM8450 support to the EPF MHI driver
- Use iATU for EPF MHI transfers smaller than 4K to avoid eDMA setup
latency
- Add sa8775p DT binding and driver support
Rockchip PCIe controller driver:
- Use 64-bit mask on MSI 64-bit PCI address to avoid zeroing out the
upper 32 bits
SiFive FU740 PCIe controller driver:
- Set the supported number of MSI vectors so we can use all available MSI
interrupts
Synopsys DesignWare PCIe controller driver:
- Add generic dwc suspend/resume APIs (dw_pcie_suspend_noirq() and
dw_pcie_resume_noirq()) to be called by controller driver
suspend/resume ops, and a controller callback to send PME_Turn_Off
MicroSemi Switchtec management driver:
- Add support for PCIe Gen5 devices
Miscellaneous:
- Reorder and compress to reduce size of struct pci_dev
- Fix race in DOE destroy_work_on_stack()
- Add stubs to avoid casts between incompatible function types
- Explicitly include correct DT includes to untangle headers
----------------------------------------------------------------

Revert "PCI: Mark NVIDIA T4 GPUs to avoid bus reset" (2023-09-08 15:11:45 -0500)
----------------------------------------------------------------
- Add PCI_DYNAMIC_OF_NODES dependency on OF_IRQ to fix sparc64 build error
(Lizhi Hou)
- After coalescing host bridge resources, free any released resources to
avoid a leak (Ross Lagerwall)
- Revert a quirk that prevented NVIDIA T4 GPUs from using Secondary Bus
Reset. The quirk worked around an issue that we now think is related to
the Root Port, not the GPU (Bjorn Helgaas)
