Thank you!
This includes several Synopsys DesignWare eDMA controller driver changes that are in drivers/dma, not drivers/pci. These lead up to eDMA support in PCIe Root Port and Endpoint drivers and have been acked by Vinod. The following changes since commit 1b929c02afd37871d5afb9d498426f83432e71c2: Linux 6.2-rc1 (2022-12-25 13:41:39 -0800) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci.git tags/pci-v6.3-changes for you to fetch changes up to 3eb5d0f26f4ea604e83ca499a72c0d33638f4765: Merge branch 'pci/misc' (2023-02-22 13:47:32 -0600) ---------------------------------------------------------------- Enumeration: - Rework portdrv shutdown so it disables interrupts but doesn't disable bus mastering, which leads to hangs on Loongson LS7A. - Add mechanism to prevent Max_Read_Request_Size (MRRS) increases, again to avoid hardware issues on Loongson LS7A (and likely other devices based on DesignWare IP). - Ignore devices with a firmware (DT or ACPI) node that says the device is disabled. 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. Tried this in v6.1 but had to revert for regressions, so try again. - Fix root bus issue that dropped resources that happened to end at 0, e.g., [bus 00]. PCI device hotplug: - Remove device locking when marking device as disconnected so this doesn't have to wait for concurrent driver bind/unbind to complete. - Quirk more Qualcomm bridges that don't fully implement the PCIe Slot Status 'Command Completed' bit. Power management: - Account for _S0W of the target bridge in acpi_pci_bridge_d3() so we don't miss hot-add notifications for USB4 docks, Thunderbolt, etc. Reset: - Observe delay after reset, e.g., resuming from system sleep, regardless of whether a bridge can suspend to D3cold at runtime. - Wait for secondary bus to become ready after a bridge reset. Virtualization: - Avoid FLR on some AMD FCH AHCI adapters where it doesn't work. - Allow independent IOMMU groups for some Wangxun NICs that prevent peer-to-peer transactions but don't advertise an ACS Capability. Error handling: - Configure End-to-End-CRC (ECRC) only if Linux owns the AER Capability. - Remove redundant Device Control Error Reporting Enable in the AER service driver since this is already done for all devices during enumeration. ASPM: - Add pci_enable_link_state() interface to allow drivers to enable ASPM link state. Endpoint framework: - Move dra7xx and tegra194 linkup processing from hard IRQ to threaded IRQ handler. - Add a separate lock for endpoint controller list of endpoint function drivers to prevent deadlock in callbacks. - Pass events from endpoint controller to endpoint function drivers via callbacks instead of notifiers. Synopsys DesignWare eDMA controller driver (acked by Vinod): - Fix CPU vs PCI address issues. - Fix source vs destination address issues. - Fix issues with interleaved transfer semantics. - Fix channel count initialization issue (issue still exists in several other drivers). - Clean up and improve debugfs usage so it will work on platforms with several eDMA devices. Baikal T-1 PCIe controller driver: - Set a 64-bit DMA mask. Freescale i.MX6 PCIe controller driver: - Add i.MX8MM, i.MX8MQ, i.MX8MP endpoint mode DT binding and driver support. Intel VMD host bridge driver: - Add quirk to configure PCIe ASPM and LTR. This is normally done by BIOS, and will be for future products. Marvell MVEBU PCIe controller driver: - Mark this driver as broken in Kconfig since bugs prevent its daily usage. MediaTek MT7621 PCIe controller driver: - Delay PHY port initialization to improve boot reliability for ZBT WE1326, ZBT WF3526-P, and some Netgear models. Qualcomm PCIe controller driver: - Add MSM8998 DT compatible string. - Unify MSM8996 and MSM8998 clock orderings. - Add SM8350 DT binding and driver support. - Add IPQ8074 Gen3 DT binding and driver support. - Correct qcom,perst-regs in DT binding. - Add qcom_pcie_host_deinit() so the PHY is powered off and regulators and clocks are disabled on late host-init errors. Socionext UniPhier Pro5 controller driver: - Clean up uniphier-ep reg, clocks, resets, and their names in DT binding. Synopsys DesignWare PCIe controller driver: - Restrict coherent DMA mask to 32 bits for MSI, but allow controller drivers to set 64-bit streaming DMA mask. - Add eDMA engine support in both Root Port and Endpoint controllers. Miscellaneous: - Remove MODULE_LICENSE from boolean drivers so they don't look like modules so modprobe can complain about them. ---------------------------------------------------------------- Alexey V.
