Merge branch 'pci/misc' (2023-10-28 13:31:05 -0500)
----------------------------------------------------------------
Enumeration:
- Use acpi_evaluate_dsm_typed() instead of open-coding _DSM evaluation to
learn device characteristics (Andy Shevchenko)
- Tidy multi-function header checks using new PCI_HEADER_TYPE_MASK
definition (Ilpo Järvinen)
- Simplify config access error checking in various drivers (Ilpo
Järvinen)
- Use pcie_capability_clear_word() (not
pcie_capability_clear_and_set_word()) when only clearing (Ilpo
Järvinen)
- Add pci_get_base_class() to simplify finding devices using base class
only (ignoring subclass and programming interface) (Sui Jingfeng)
- Add pci_is_vga(), which includes ancient PCI_CLASS_NOT_DEFINED_VGA
devices from before the Class Code was added to PCI (Sui Jingfeng)
- Use pci_is_vga() for vgaarb, sysfs "boot_vga", virtio, qxl to include
ancient VGA devices (Sui Jingfeng)
Resource management:
- Make pci_assign_unassigned_resources() non-init because sparc uses it
after init (Randy Dunlap)
Driver binding:
- Retain .remove() and .probe() callbacks (previously __init) because
sysfs may cause them to be called later (Uwe Kleine-König)
- Prevent xHCI driver from claiming AMD VanGogh USB3 DRD device, so it
can be claimed by dwc3 instead (Vicki Pfau)
PCI device hotplug:
- Add Ampere Altra Attention Indicator extension driver for acpiphp
(D Scott Phillips)
Power management:
- Quirk VideoPropulsion Torrent QN16e with longer delay after reset
(Lukas Wunner)
- Prevent users from overriding drivers that say we shouldn't use D3cold
(Lukas Wunner)
- Avoid PME from D3hot/D3cold for AMD Rembrandt and Phoenix USB4 because
wakeup interrupts from those states don't work if amd-pmc has put the
platform in a hardware sleep state (Mario Limonciello)
IOMMU:
- Disable ATS for Intel IPU E2000 devices with invalidation message
endianness erratum (Bartosz Pawlowski)
Error handling:
- Factor out interrupt enable/disable into helpers (Kai-Heng Feng)
Peer-to-peer DMA:
- Fix flexible-array usage in struct pci_p2pdma_pagemap in case we ever
use pagemaps with multiple entries (Gustavo A. R. Silva)
ASPM:
- Revert a change that broke when drivers disabled L1 and users later
enabled an L1.x substate via sysfs, and fix a similar issue when users
disabled L1 via sysfs (Heiner Kallweit)
Endpoint framework:
- Fix double free in __pci_epc_create() (Dan Carpenter)
- Use IS_ERR_OR_NULL() to simplify endpoint core (Ruan Jinjie)
Cadence PCIe controller driver:
- Drop unused "is_rc" member (Li Chen)
Freescale Layerscape PCIe controller driver:
- Enable 64-bit addressing in endpoint mode (Guanhua Gao)
Intel VMD host bridge driver:
- Fix multi-function header check (Ilpo Järvinen)
Microsoft Hyper-V host bridge driver:
- Annotate struct hv_dr_state with __counted_by (Kees Cook)
NVIDIA Tegra194 PCIe controller driver:
- Drop setting of LNKCAP_MLW (max link width) since dw_pcie_setup()
already does this via dw_pcie_link_set_max_link_width() (Yoshihiro
Shimoda)
Qualcomm PCIe controller driver:
- Use PCIE_SPEED2MBS_ENC() to simplify encoding of link speed (Manivannan
Sadhasivam)
- Add a .write_dbi2() callback so DBI2 register writes, e.g., for setting
the BAR size, work correctly (Manivannan Sadhasivam)
- Enable ASPM for platforms that use 1.9.0 ops, because the PCI core
doesn't enable ASPM states that haven't been enabled by the firmware
(Manivannan Sadhasivam)
Renesas R-Car Gen4 PCIe controller driver:
- Add DesignWare core support (set max link width, EDMA_UNROLL flag,
.pre_init(), .deinit(), etc) for use by R-Car Gen4 driver (Yoshihiro
Shimoda)
- Add driver and DT schema for DesignWare-based Renesas R-Car Gen4
controller in both host and endpoint mode (Yoshihiro Shimoda)
Xilinx NWL PCIe controller driver:
- Update ECAM size to support 256 buses (Thippeswamy Havalige)
- Stop setting bridge primary/secondary/subordinate bus numbers, since
PCI core does this (Thippeswamy Havalige)
Xilinx XDMA controller driver:
- Add driver and DT schema for Zynq UltraScale+ MPSoCs devices with
Xilinx XDMA Soft IP (Thippeswamy Havalige)
Miscellaneous:
- Use FIELD_GET()/FIELD_PREP() to simplify and reduce use of _SHIFT
macros (Ilpo Järvinen, Bjorn Helgaas)
- Remove logic_outb(), _outw(), outl() duplicate declarations (John
Sanpe)
- Replace unnecessary UTF-8 in Kconfig help text because menuconfig
doesn't render it correctly (Liu Song)
