Thank you!
The following changes since commit 568035b01cfb107af8d2e4bd2fb9aea22cf5b868: Linux 6.0-rc1 (2022-08-14 15:50:18 -0700) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci.git tags/pci-v6.1-changes for you to fetch changes up to 0e00a3aeae255416577fc69b9b49be4778c05464: Merge branch 'for-linus' into next (2022-10-06 16:06:56 -0500) ---------------------------------------------------------------- Resource management: - Distribute spare resources to unconfigured hotplug bridges at boot-time (not just when hot-adding such a bridge), which makes hot-adding devices to docks work better. - Revert to a BAR assignment inherited from firmware only when the address is actually reachable via any upstream bridges, which fixes some cases where firmware doesn't configure all devices. - Add a sysfs interface to resize BARs so this can be done before assigning devices to a VM through VFIO. Power management: - Disable Precision Time Management for all devices on suspend to enable lower-power PM state. We previously did this just for Root Ports, which isn't enough because downstream devices can still generate PTM messages, which cause errors if it's disabled in the Root Port. - Save and restore the ASPM L1 PM Substates configuration for suspend/ resume. Previously this configuration was lost, so L1.x states likely stopped working after resume. - Check whether the L1 PM Substates Capability exists. If it didn't exist, we previously read junk and tried to configure L1 Substates based on that. - Fix the LTR_L1.2_THRESHOLD computation, which previously set a threshold for entering L1.2 that was too low in some cases. - Reduce the delay after transitions to or from D3cold by using usleep_range() rather than msleep(), which often slept for ~19ms instead of the 10ms normally required. The spec says 10ms is enough, but it's possible we could trip over devices that need a little more. Error handling: - Work around a BIOS bug that caused Intel Root Ports to advertise a Root Port Programmed I/O (RP PIO) log size of zero, which caused annoying warnings and prevented the kernel from dumping log registers for DPC errors. Qualcomm PCIe controller driver: - Add support for SC8280XP and SA8540P host controllers and SM8450 endpoint controller. - Disable Master AXI clock on endpoint controllers to save power when link is idle or in L1.x. - Expose link state transition counts via debugfs to help debug issues with low-power states. - Add auto-loading module support. Synopsys DesignWare PCIe controller driver: - Remove a dependency on ZONE_DMA32 by allocating the MSI target page differently. There's more work to do related to eDMA controllers, so it's not completely settled. ---------------------------------------------------------------- Alex Williamson (1): PCI: Expose PCIe Resizable BAR support via sysfs Andy Shevchenko (1): PCI: dwc: Replace of_gpio_named_count() by gpiod_count() Bjorn Helgaas (29): PCI/PTM: Cache PTM Capability offset PCI/PTM: Add pci_upstream_ptm() helper PCI/PTM: Separate configuration and enable PCI/PTM: Add pci_suspend_ptm() and pci_resume_ptm() PCI/PTM: Move pci_ptm_info() body into its only caller PCI/PTM: Preserve RsvdP bits in PTM Control register PCI/PTM: Reorder functions in logical order PCI/PTM: Consolidate PTM interface declarations PCI/PM: Always disable PTM for all devices during suspend PCI/ASPM: Factor out L1 PM Substates configuration PCI/ASPM: Ignore L1 PM Substates if device lacks capability PCI/ASPM: Correct LTR_L1.2_THRESHOLD computation Merge branch 'pci/aspm' Merge branch 'pci/dpc' Merge branch 'pci/msi' Merge branch 'pci/pm' Merge branch 'pci/rebar' Merge branch 'pci/resource' Merge branch 'remotes/lorenzo/pci/aardvark' Merge branch 'remotes/lorenzo/pci/apple' Merge branch 'remotes/lorenzo/pci/bridge-emul' Merge branch 'remotes/lorenzo/pci/dt' Merge branch 'remotes/lorenzo/pci/dwc' Merge branch 'remotes/lorenzo/pci/mediatek' Merge branch 'remotes/lorenzo/pci/mvebu' Merge branch 'pci/qcom' Merge branch 'remotes/lorenzo/pci/misc' Merge branch 'pci/misc' Merge branch 'for-linus' into next Conor Dooley (3): dt-bindings: PCI: fu740-pci: fix missing clock-names dt-bindings: PCI: microchip,pcie-host: fix missing clocks properties dt-bindings: PCI: microchip,pcie-host: fix missing dma-ranges Dmitry Baryshkov (1): PCI: qcom-ep: Add MODULE_DEVICE_TABLE Dmitry Torokhov (1): PCI: apple: Do not leak reset GPIO on unbind/unload/error Felix Fietkau (1): PCI: mediatek-gen3: Change driver name to mtk-pcie-gen3 Jianjun Wang (1): dt-bindings: PCI: mediatek-gen3: Add support for MT8188 and MT8195 Johan Hovold (10): dt-bindings: PCI: qcom: Enumerate platforms with single msi interrupt dt-bindings: PCI: qcom: Add SC8280XP to binding dt-bindings: PCI: qcom: Add SA8540P to binding PCI: qcom: Add support for SC8280XP PCI: qcom: Add support for SA8540P PCI: qcom: Make all optional clocks optional PCI: qcom: Clean up IP configurations PCI: qcom: Sort device-id table PCI: qcom: Drop unused post_deinit callback PCI: qcom: Rename host-init error label Josef Johansson (1): PCI/MSI: Correct 'can_mask' test in msi_add_msi_desc() Krishna chaitanya chundru (1): dt-bindings: pci: QCOM Add missing sc7280 aggre0, aggre1 clocks Maciej W.
