Pull PCI updates from Bjorn Helgaas:
"Resource management:
- Add hotplug reservation only once (not at each level of the
hierarchy) so bridge windows don't grow more than necessary (Ilpo
Järvinen)
Driver binding:
- Rework device matching so device ID lifetime only needs to cover
the probe path since dynamic IDs can be removed at any time (Gary
Guo)
Error handling:
- Update mappings of AER errors to agent & layer and log them for
each individual error when multiple errors detected (Lukas Wunner)
- Log Error Source only once, not twice in separate messages (Lukas
Wunner)
- Emit TLP Log only for unmasked errors (Lukas Wunner)
- Support Advisory Non-Fatal Errors (Lukas Wunner)
- Allow DPC on all Downstream Ports, not just Root Ports, when OS
controls AER (Darshit Shah)
ASPM:
- Program the same ASPM Control values for every function of
multi-function devices, as recommended by the PCIe spec (Krishna
Chaitanya Chundru)
- Avoid L0s for Realtek RTS525A, where it causes an AER interrupt
storm (Max Lee)
- Avoid ASPM L0s, L1, and L1 PM Substates based on 'aspm-no-l0s',
'aspm-no-l1' [1], and 'aspm-no-l1ss' DT properties (Krishna
Chaitanya Chundru)
Power management:
- Allow D3 for native hotplug-capable Root Ports on non-x86 platforms
(we avoid D3 for these ports on x86 because some old platforms
didn't validate it) (Manivannan Sadhasivam)
- Allow portdrv to claim Ports even if they don't support services
(AER, PME, DPC, hotplug, etc) so it can do power management (Brian
Norris)
Power control:
- Add support for PCIe WAKE# interrupt when described via DT (Krishna
Chaitanya Chundru)
- For the TC9563 PCIe switch:
- Take a reference on the I2C adapter to avoid uninterruptible
hang when unloading an I2C module while in-use (Johan Hovold)
- Update DT binding and driver to restrict Tx Amplitude, DFE and
N_FTS to USP, DSP1 and DSP2 (Manivannan Sadhasivam)
- Power off only external-facing ports (DSP1, DSP2), leaving USP
and DSP3 (aka VDSP) powered up (Manivannan Sadhasivam)
- Move integrated MAC Endpoint out of the list of internal ports
and configure it separately (Manivannan Sadhasivam)
Virtualization:
- Add ACS quirk for Pericom PI7C9X2G608 switches (Tim Harvey)
- Fix a long-standing bug in the Intel PCH Root Port MPC ACS quirk
that didn't update the intended INTEL_MPC_REG_IRBNCE bit because it
used a 16-bit config write when a 32-bit write was intended
(Mohamad Raizudeen)
Procfs:
- Avoid spurious runtime PM wakeup on config space accesses that are
outside config space and fail before reaching PCI (Krzysztof
Wilczyński)
- Warn on user-space writes to kernel-exclusive config space regions,
as we already do for sysfs (Krzysztof Wilczyński)
- Check credentials of opener, not reader, for config space reads, as
we already do for sysfs (Krzysztof Wilczyński)
Sysfs:
- In pci_write_legacy_io(), avoid out-of-bounds reads from the user
buffer and fix incorrect ioport write data (1-byte writes on
little-endian powerpc, 2- and 4-byte writes on big-endian powerpc)
(Krzysztof Wilczyński)
- In pci_read_legacy_io(), fix incorrect ioport read data for 2- and
4-byte reads on big-endian powerpc (Krzysztof Wilczyński)
- Fix I/O port accessor argument order in Alpha pci_legacy_write()
(Krzysztof Wilczyński)
- Avoid spurious runtime PM wakeup on config space accesses that are
outside config space and fail before reaching PCI (Krzysztof
Wilczyński)
- Return -EINVAL, not -ENODEV, for mmap of I/O BAR that fails because
the arch doesn't support it, as we do for procfs (Krzysztof
Wilczyński)
- Check for LOCKDOWN_PCI_ACCESS for legacy_io and legacy_mem, as we
do for other config space accessors (Krzysztof Wilczyński)
Peer-to-peer DMA:
- Add Nvidia Vera Rubin to list of platforms that support P2PDMA
(Leon Romanovsky)
Endpoint framework:
- Check doorbell SUCCESS bit in pci_endpoint_test to avoid treating
some failures as successes (Niklas Cassel)
- Fail doorbell test when the trigger IRQ is missed (Niklas Cassel)
New native PCIe controller drivers:
- Add DT binding and driver for NVIDIA Tegra264 (Thierry Reding)
Native PCIe controllers:
- Use common wait time definitions for PCIe link monitoring instead
of defining driver-private duplicates (Thierry Reding)
Generic host bridge driver:
- Fix NULL pointer dereference that caused enumeration failures on
32-bit CAM systems (Steffen Persvold)
Amlogic Meson PCIe controller driver:
- Correct the PERST# GPIO state so it remains asserted until power
and REFCLK become stable to fix enumeration failure (Ronald
Claveau)
ASPEED PCIe controller driver:
- Switch to irq_domain_create_linear() so we can obsolete
irq_domain_add_linear() (Jiri Slaby)
Cadence PCIe controller driver:
- Add MODULE_DEVICE_TABLE to generate module aliases for OF-based
module autoloading (Pengpeng Hou)
- Add debugfs 'ltssm_status' file for LGA- and HPA-based Cadence
controllers (Hans Zhang)
- Support up to x4 (not x2) lanes for J200 (Takuma Fujiwara)
- Fix host/endpoint dependencies for cadence-plat driver to fix link
error when cadence-plat is built-in but the host or endpoint driver
is modular (Aksh Garg)
Freescale i.MX6 PCIe controller driver:
- Add imx6 intr/aer/pme interrupt lines for i.MX95 (Richard Zhu)
- Remove PERST# checking from pci_host_common_parse_port() so callers
can decide whether to fall back to legacy DT binding with PERST# in
the host bridge (Sherry Sun)
- Fix build issues when PCI_PWRCTRL_GENERIC or PCI_HOST_COMMON is a
module (Arnd Bergmann)
- Create pwrctrl devices only once by doing it from imx_pcie_probe()
instead of imx_pcie_host_init(), which is used during both probe
and resume (Sherry Sun)
- Use 'dw_pcie_rp->skip_pwrctrl_off' to avoid powering off devices
during suspend to preserve wakeup capability (Sherry Sun)
- Add runtime PM support for i.MX95 to allow dynamic power management
when the link is idle (Richard Zhu)
Intel VMD host bridge driver:
- Support device ID 0x28C1 and assume that BIOS has already
enumerated the hierarchy below VMD and stored bus range info for OS
to use (Nirmal Patel)
- Add support for VMCONFIG BUS_RESTRICT_CFG=3, which makes it
possible to enumerate downstream devices on Intel Arrow Lake-HX
systems and probably others (Ali Alaei)
- Pay attention to _OSC negotiation for VMD hierarchy only when
running on bare metal, not when running in a VM (Nirmal Patel)
- Add Nova Lake (NVL) and Dunlow (DNL) Device IDs (Szymon Durawa)
MediaTek PCIe controller driver:
- Add support for PCIe controller in EcoNet EN7528 and EN751221 SoCs
(Caleb James DeLisle)
MediaTek PCIe Gen3 controller driver:
- Add mediatek-gen3 'memory-region' for restricted DMA buffer
(Chen-Yu Tsai)
NVIDIA Tegra264 PCIe controller driver:
- Distinguish Tegra264 C0 PCIe controller for internal GPU from C1-C5
controllers so the unit address matches the first 'reg' entry
(Thierry Reding)
- Add Tegra264 Root Port stanzas to prepare for generic WAKE#
handling (Thierry Reding)
Qualcomm PCIe controller driver:
- Add IPQ9650 compatible with global interrupt (Kathiravan
Thirumoorthy)
- Add IPQ5210 compatible with IPQ9574 fallback (Varadarajan
Narayanan)
- Add DT binding and driver support for Hawi SoC (Matthew Leung)
- Skip PERST# GPIOs provided by downstream PCIe devices, which should
be handled by drivers of those devices (Manivannan Sadhasivam)
- Stop advertising Attention Button Present (no Qcom SoCs support
Attention Buttons) so pciehp can use Presence Detect Changed events
(Qiang Yu)
Renesas R-Car PCIe controller driver:
- Add rcar-gen4-pci-host optional 'msi-parent' for GIT ITS (Marek
Vasut)
- When MSI is enabled but iMSI-RX is not used, configure AXIINTC to
allow GIT ITS to handle MSI (Marek Vasut)
- Refactor GIC600 implementation to make it easier to add platforms
that only support 32-bit addressing (Marek Vasut)
- Add Renesas R-Car Gen4 S4/V4H/V4M to the list of GIC600
integrations that only support 32-bit addressing (Marek Vasut)
Renesas RZ/G3S PCIe controller driver:
- Add DT binding and driver support for RZ/V2H(P) SoC, which contains
two PCIe controllers, configured either as a single x4 link or two
independent x2 link controllers (Lad Prabhakar)
SpacemiT K1 PCIe controller driver:
- Add missing MODULE_DEVICE_TABLE() to generate module alias info for
OF-based module autoloading (Pengpeng Hou)
StarFive PCIe controller driver:
- Fix resource leaks on error paths in host_init() (Ali Tariq)
- Fix runtime PM handling and teardown ordering to avoid register
access while power or clocks are disabled (Ali Tariq)
- Check for runtime PM resume failure to avoid register access while
power or clocks are disabled (Ali Tariq)
Synopsys DesignWare PCIe controller driver:
- Add LECARC PMU IDs to the DWC RAS/DES VSEC list so it can take
advantage of the existing debugfs support for silicon debug, error
injection, and event counters (Brett Zhou)
- Factor pcie_valid_speed() and pci_bus_speed2lnkctl2() out of bwctrl
so they can be shared by the DWC core (Hans Zhang)
- Flush MSI writes from endpoint before unmapping the iATU, as we
already do for MSI-X writes (Niklas Cassel)
- Unmap MSI iATU window before mapping MSI-X window, to avoid a
subsequent MSI write using a disabled aperture and losing the
interrupt (Niklas Cassel)
- Change endpoint .pre_init() and .init() callbacks to return errors
and handle them (Marek Vasut)
UltraRISC PCIe controller driver:
- Add 'core', 'dbi', and 'aux' clocks to DT binding and manage them
in the driver (Jia Wang)
- Use module_platform_driver() since this may be built as a module,
though not removable because IRQs can't be safely disposed (Jia
Wang)
MicroSemi Switchtec management driver:
- Add Microchip PCI1008 device ID and include it in NTB DMA alias
quirk (Logan Gunthorpe)
Miscellaneous:
- Document how to write PCI Host Controller drivers (Manivannan
Sadhasivam)
- Fix typos in documentation (D'Orus Tsitera)
- Use %pe format specifier to print error pointers so we get symbolic
errname when available (Krzysztof Wilczyński)"
