Merge branch 'remotes/lorenzo/pci/xgene' (2021-11-05 11:28:53 -0500)

----------------------------------------------------------------

I don't think you'll see any conflicts, but you will see an apple-dart.c
build failure unless you add the patch below. b2b2781a9755 ("iommu/dart:
Clean up IOVA cookie crumbs") removed an #include that is now required
again by 946d619fa25f ("iommu/dart: Exclude MSI doorbell from PCIe device
IOVA range")

----------------------------------------------------------------

Enumeration:
- Conserve IRQs by setting up portdrv IRQs only when there are users (Jan
Kiszka)
- Rework and simplify _OSC negotiation for control of PCIe features
(Joerg Roedel)
- Remove struct pci_dev.driver pointer since it's redundant with the
struct device.driver pointer (Uwe Kleine-König)

Resource management:
- Coalesce contiguous host bridge apertures from _CRS to accommodate BARs
that cover more than one aperture (Kai-Heng Feng)

Sysfs:
- Check CAP_SYS_ADMIN before parsing user input (Krzysztof Wilczyński)
- Return -EINVAL consistently from "store" functions (Krzysztof
Wilczyński)
- Use sysfs_emit() in endpoint "show" functions to avoid buffer overruns
(Kunihiko Hayashi)

PCIe native device hotplug:
- Ignore Link Down/Up caused by resets during error recovery so endpoint
drivers can remain bound to the device (Lukas Wunner)

Virtualization:
- Avoid bus resets on Atheros QCA6174, where they hang the device (Ingmar
Klein)
- Work around Pericom PI7C9X2G switch packet drop erratum by using store
and forward mode instead of cut-through (Nathan Rossi)
- Avoid trying to enable AtomicOps on VFs; the PF setting applies to all
VFs (Selvin Xavier)

MSI:
- Document that /sys/bus/pci/devices/.../irq contains the legacy INTx
interrupt or the IRQ of the first MSI (not MSI-X) vector (Barry Song)

VPD:
- Add pci_read_vpd_any() and pci_write_vpd_any() to access anywhere in
the possible VPD space; use these to simplify the cxgb3 driver (Heiner
Kallweit)

Peer-to-peer DMA:
- Add (not subtract) the bus offset when calculating DMA address (Wang
Lu)

ASPM:
- Re-enable LTR at Downstream Ports so they don't report Unsupported
Requests when reset or hot-added devices send LTR messages (Mingchuang
Qiao)

Apple PCIe controller driver:
- Add driver for Apple M1 PCIe controller (Alyssa Rosenzweig, Marc
Zyngier)

Cadence PCIe controller driver:

Carvalho Chehab)
- Support PERST# GPIOs for HiKey970 external PEX 8606 bridge (Mauro
Carvalho Chehab)
- Add Kirin 970 support (Mauro Carvalho Chehab)
- Make driver removable (Mauro Carvalho Chehab)

Intel VMD host bridge driver:
- If IOMMU supports interrupt remapping, leave VMD MSI-X remapping
enabled (Adrian Huang)
- Number each controller so we can tell them apart in /proc/interrupts
(Chunguang Xu)
- Avoid building on UML because VMD depends on x86 bare metal APIs
(Johannes Berg)

Marvell Aardvark PCIe controller driver:
- Define macros for PCI_EXP_DEVCTL_PAYLOAD_* (Pali Rohár)

- Read entire 16-bit MSI vector in MSI handler, not just low 8 bits (Marek
Behún)
- Clear Root Port I/O Space, Memory Space, and Bus Master Enable bits at
startup; PCI core will set those as necessary (Pali Rohár)
- When operating as a Root Port, set class code to "PCI Bridge" instead of
the default "Mass Storage Controller" (Pali Rohár)
- Add emulation for PCI_BRIDGE_CTL_BUS_RESET since aardvark doesn't
implement this per spec (Pali Rohár)

spec (Pali Rohár)

Cao)

Wilczyński)
