drm/amdgpu: The interrupt source was not released

2025-07-15T18:07:51+00:00

When the driver is unloaded, the interrupt source of the rma device is not released, resulting in the failure of hw_init when loading again using bad_page_threshold. Signed-off-by: Ce Sun Reviewed-by: Tao Zhou Signed-off-by: Alex Deucher

drm/amdgpu: fix fence fallback timer expired error

2025-06-18T16:19:15+00:00

IH is not working after switching a new gpu index for the first time. During VM resume, QEMU programming of VF MSIX table (register GFXMSIX_VECT0_ADDR_LO) may not work.The access could be blocked by nBIF protection as VF isn't in exclusive access mode. Exclusive access is enabled now, disable/enable MSIX so that QEMU reprograms MSIX table. call amdgpu_restore_msix on resume to restore msix table.

Pull drm updates from Dave Airlie: "As part of building up nova-core/nova-drm pieces we've brought in some rust abstractions through this tree, aux bus being the main one, with devres changes also in the driver-core tree. Along with the drm core abstractions and enough nova-core/nova-drm to use them. This is still all stub work under construction, to build the nova driver upstream. The other big NVIDIA related one is nouveau adds support for Hopper/Blackwell GPUs, this required a new GSP firmware update to 570.144, and a bunch of rework in order to support multiple fw interfaces. There is also the introduction of an asahi uapi header file as a precursor to getting the real driver in later, but to unblock userspace mesa packages while the driver is trapped behind rust enablement.

gpu: Switch to irq_domain_create_linear()

2025-05-16T19:06:09+00:00

irq_domain_add_linear() is going away as being obsolete now. Switch to the preferred irq_domain_create_linear(). That differs in the first parameter: It takes more generic struct fwnode_handle instead of struct device_node. Therefore, of_fwnode_handle() is added around the parameter. Note some of the users can likely use dev->fwnode directly instead of indirect of_fwnode_handle(dev->of_node). But dev->fwnode is not guaranteed to be set for all, so this has to be investigated on case to case basis (by people who can actually test with the HW).

Pull pci updates from Bjorn Helgaas: "Enumeration: - Skip E820 checks for MCFG ECAM regions for new (2016+) machines, since there's no requirement to describe them in E820 and some platforms require ECAM to work (Bjorn Helgaas) - Rename PCI_IRQ_LEGACY to PCI_IRQ_INTX to be more specific (Damien Le Moal) - Remove last user and pci_enable_device_io() (Heiner Kallweit) - Wait for Link Training==0 to avoid possible race (Ilpo Järvinen) - Skip waiting for devices that have been disconnected while suspended (Ilpo Järvinen) - Clear Secondary Status errors after enumeration since Master Aborts and Unsupported Request errors are an expected part of enumeration (Vidya Sagar) MSI: - Remove unused IMS (Interrupt Message Store) support (Bjorn Helgaas) Error handling: - Mask Genesys GL975x SD host controller Replay Timer Timeout correctable errors caused by a hardware defect; the errors cause interrupts that prevent system suspend (Kai-Heng Feng) - Fix EDR-related _DSM support, which previously evaluated revision 5 but assumed revision 6 behavior (Kuppuswamy Sathyanarayanan) ASPM: - Simplify link state definitions and mask calculation (Ilpo Järvinen) Power management: - Avoid D3cold for HP Pavilion 17 PC/1972 PCIe Ports, where BIOS apparently doesn't know how to put them back in D0 (Mario Limonciello) CXL: - Support resetting CXL devices; special handling required because CXL Ports mask Secondary Bus Reset by default (Dave Jiang) DOE: - Support DOE Discovery Version 2 (Alexey Kardashevskiy) Endpoint framework: - Set endpoint BAR to be 64-bit if the driver says that's all the device supports, in addition to doing so if the size is >2GB (Niklas Cassel) - Simplify endpoint BAR allocation and setting interfaces (Niklas Cassel) Cadence PCIe controller driver: - Drop DT binding redundant msi-parent and pci-bus.yaml (Krzysztof Kozlowski) Cadence PCIe endpoint driver: - Configure endpoint BARs to be 64-bit based on the BAR type, not the BAR value (Niklas Cassel) Freescale Layerscape PCIe controller driver: - Convert DT binding to YAML (Frank Li) MediaTek MT7621 PCIe controller driver: - Add DT binding missing 'reg' property for child Root Ports (Krzysztof Kozlowski) - Fix theoretical string truncation in PHY name (Sergio Paracuellos) NVIDIA Tegra194 PCIe controller driver: - Return success for endpoint probe instead of falling through to the failure path (Vidya Sagar) Renesas R-Car PCIe controller driver: - Add DT binding missing IOMMU properties (Geert Uytterhoeven) - Add DT binding R-Car V4H compatible for host and endpoint mode (Yoshihiro Shimoda) Rockchip PCIe controller driver: - Configure endpoint BARs to be 64-bit based on the BAR type, not the BAR value (Niklas Cassel) - Add DT binding missing maxItems to ep-gpios (Krzysztof Kozlowski) - Set the Subsystem Vendor ID, which was previously zero because it was masked incorrectly (Rick Wertenbroek) Synopsys DesignWare PCIe controller driver: - Restructure DBI register access to accommodate devices where this requires Refclk to be active (Manivannan Sadhasivam) - Remove the deinit() callback, which was only need by the pcie-rcar-gen4, and do it directly in that driver (Manivannan Sadhasivam) - Add dw_pcie_ep_cleanup() so drivers that support PERST# can clean up things like eDMA (Manivannan Sadhasivam) - Rename dw_pcie_ep_exit() to dw_pcie_ep_deinit() to make it parallel to dw_pcie_ep_init() (Manivannan Sadhasivam) - Rename dw_pcie_ep_init_complete() to dw_pcie_ep_init_registers() to reflect the actual functionality (Manivannan Sadhasivam) - Call dw_pcie_ep_init_registers() directly from all the glue drivers, not just those that require active Refclk from the host (Manivannan Sadhasivam) - Remove the "core_init_notifier" flag, which was an obscure way for glue drivers to indicate that they depend on Refclk from the host (Manivannan Sadhasivam) TI J721E PCIe driver: - Add DT binding J784S4 SoC Device ID (Siddharth Vadapalli) - Add DT binding J722S SoC support (Siddharth Vadapalli) TI Keystone PCIe controller driver: - Add DT binding missing num-viewport, phys and phy-name properties (Jan Kiszka) Miscellaneous: - Constify and annotate with __ro_after_init (Heiner Kallweit) - Convert DT bindings to YAML (Krzysztof Kozlowski) - Check for kcalloc() failure in of_pci_prop_intr_map() (Duoming Zhou)" * tag 'pci-v6.10-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci: (97 commits) PCI: Do not wait for disconnected devices when resuming x86/pci: Skip early E820 check for ECAM region PCI: Remove unused pci_enable_device_io() ata: pata_cs5520: Remove unnecessary call to pci_enable_device_io() PCI: Update pci_find_capability() stub return types PCI: Remove PCI_IRQ_LEGACY scsi: vmw_pvscsi: Do not use PCI_IRQ_LEGACY instead of PCI_IRQ_LEGACY scsi: pmcraid: Use PCI_IRQ_INTX instead of PCI_IRQ_LEGACY scsi: mpt3sas: Use PCI_IRQ_INTX instead of PCI_IRQ_LEGACY scsi: megaraid_sas: Use PCI_IRQ_INTX instead of PCI_IRQ_LEGACY scsi: ipr: Use PCI_IRQ_INTX instead of PCI_IRQ_LEGACY scsi: hpsa: Use PCI_IRQ_INTX instead of PCI_IRQ_LEGACY scsi: arcmsr: Use PCI_IRQ_INTX instead of PCI_IRQ_LEGACY wifi: rtw89: Use PCI_IRQ_INTX instead of PCI_IRQ_LEGACY dt-bindings: PCI: rockchip,rk3399-pcie: Add missing maxItems to ep-gpios Revert "genirq/msi: Provide constants for PCI/IMS support" Revert "x86/apic/msi: Enable PCI/IMS" Revert "iommu/vt-d: Enable PCI/IMS" Revert "iommu/amd: Enable PCI/IMS" Revert "PCI/MSI: Provide IMS (Interrupt Message Store) support" ...
