irqchip: Add Broadcom BCM2712 MSI-X interrupt controllerAdd an interrupt controller driver for MSI-X Interrupt Peripheral (MIP)hardware block found in BCM2712. The interrupt controller is used tohandle MSI-X interrupts from peripherials behind PCIe endpoints likeRPi1 south bridge found in RPi5.There are two MIPs on BCM2712, the first has 64 consecutive SPIsassigned to 64 output vectors, and the second has 17 SPIs, but only8 of them are consecutive starting at the 8th output vector.Signed-off-by: Stanimir Varbanov Reviewed-by: Thomas Gleixner Tested-by: Ivan T.

96093fe5 - irqchip: Have CONFIG_IRQ_MSI_IOMMU be selected by irqchips that need it

Thu, 20 Feb 2025 01:31:39 +0000

irqchip: Have CONFIG_IRQ_MSI_IOMMU be selected by irqchips that need itCurrently, IRQ_MSI_IOMMU is selected if DMA_IOMMU is available to providean implementation for iommu_dma_prepare/compose_msi_msg(). However, it'llmake more sense for irqchips that call prepare/compose to select it, andthat will trigger all the additional code and data to be compiled intothe kernel.If IRQ_MSI_IOMMU is selected with no IOMMU side implementation, then theprepare/compose() will be NOP stubs.If IRQ_MSI_IOMMU is not selected by an irqchip, then the related code onthe iommu side is compiled out.Link: https://patch.msgid.link/r/a2620f67002c5cdf974e89ca3bf905f5c0817be6.1740014950.git.nicolinc@nvidia.comSigned-off-by: Nicolin Chen Reviewed-by: Thomas Gleixner Signed-off-by: Jason Gunthorpe List of files: /linux-6.15/drivers/irqchip/Kconfig

322a9063 - irqchip/mips-gic: Multi-cluster support

Mon, 28 Oct 2024 17:59:26 +0000

irqchip/mips-gic: Multi-cluster supportThe MIPS I6500 CPU & CM (Coherence Manager) 3.5 introduce the concept ofmultiple clusters to the system. In these systems, each cluster containsits own GIC, so the GIC isn't truly global any longer. Access toregisters in the GICs of remote clusters is possible using a redirectregister block much like the redirect register blocks provided by theCM & CPC, and configured through the same GCR_REDIRECT register thatmips_cm_lock_other() abstraction builds upon.It is expected that external interrupts are connected identically on allclusters. That is, if there is a device providing an interrupt connectedto GIC interrupt pin 0 then it should be connected to pin 0 of every GICin the system. For the most part, the GIC can be treated as though it isstill truly global, so long as interrupts in the cluster are configuredproperly.Introduce support for such multi-cluster systems in the MIPS GIC irqchipdriver. A newly introduced gic_irq_lock_cluster() function allows: 1) Configure access to a GIC in a remote cluster via the redirect register block, using mips_cm_lock_other().Or: 2) Detect that the interrupt in question is affine to the local cluster and plain old GIC register access to the GIC in the local cluster should be used.It is possible to access the local cluster's GIC registers via theredirect block, but keeping the special case for them is both good forperformance (because we avoid the locking & indirection overhead ofusing the redirect block) and necessary to maintain compatibility withsystems using CM revisions prior to 3.5 which don't support the redirectblock.The gic_irq_lock_cluster() function relies upon an IRQs effectiveaffinity in order to discover which cluster the IRQ is affine to. Inorder to track this & allow it to be updated at an appropriate pointduring gic_set_affinity() select the generic support for effectiveaffinity using CONFIG_GENERIC_IRQ_EFFECTIVE_AFF_MASK.gic_set_affinity() is the one function which gains much complexity. Itnow deconfigures routing to any VP(E), ie. CPU, on the old cluster whenmoving affinity to a new cluster.gic_shared_irq_domain_map() moves its update of the IRQs effectiveaffinity to before its use of gic_irq_lock_cluster(), to ensure thatoperation is on the cluster the IRQ is affine to.The remaining changes are straightforward use of the gic_irq_lock_cluster()function to select between local cluster & remote cluster code-paths whenconfiguring interrupts.Signed-off-by: Paul Burton Signed-off-by: Chao-ying Fu Signed-off-by: Dragan Mladjenovic Signed-off-by: Aleksandar Rikalo Signed-off-by: Thomas Gleixner Tested-by: Serge Semin Tested-by: Gregory CLEMENT Link: https://lore.kernel.org/all/20241028175935.51250-5-arikalo@gmail.com List of files: /linux-6.15/drivers/irqchip/Kconfig
