People will never understand that APIs exist for a reason... - Provide core infrastructre for the upcoming PCI endpoint library extensions. Currently limited to ARM GICv3+, but in theory extensible to other architectures. - Provide a MSI domain::teardown() callback, which allows drivers to undo the effects of the prepare() callback. - Move the MSI domain::prepare() callback invocation to domain creation time to avoid redundant (and in case of ARM/GIC-V3-ITS confusing) invocations on every allocation. In combination with the new teardown callback this removes some ugly hacks in the GIC-V3-ITS driver, which pretended to work around the short comings of the core code so far. With this update the code is correct by design and implementation. - Make the irqchip MSI library globally available, provide a MSI parent domain creation helper and convert a bunch of (PCI/)MSI drivers over to the modern MSI parent mechanism. This is the first step to get rid of at least one incarnation of the three PCI/MSI management schemes. - The usual small cleanups and improvements" * tag 'irq-msi-2025-05-25' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (33 commits) PCI/MSI: Use bool for MSI enable state tracking PCI: tegra: Convert to MSI parent infrastructure PCI: xgene: Convert to MSI parent infrastructure PCI: apple: Convert to MSI parent infrastructure irqchip/msi-lib: Honour the MSI_FLAG_NO_AFFINITY flag irqchip/mvebu: Convert to msi_create_parent_irq_domain() helper irqchip/gic: Convert to msi_create_parent_irq_domain() helper genirq/msi: Add helper for creating MSI-parent irq domains irqchip: Make irq-msi-lib.h globally available irqchip/gic-v3-its: Use allocation size from the prepare call genirq/msi: Engage the .msi_teardown() callback on domain removal genirq/msi: Move prepare() call to per-device allocation irqchip/gic-v3-its: Implement .msi_teardown() callback genirq/msi: Add .msi_teardown() callback as the reverse of .msi_prepare() irqchip/gic-v3-its: Add support for device tree msi-map and msi-mask dt-bindings: PCI: pci-ep: Add support for iommu-map and msi-map irqchip/gic-v3-its: Set IRQ_DOMAIN_FLAG_MSI_IMMUTABLE for ITS irqdomain: Add IRQ_DOMAIN_FLAG_MSI_IMMUTABLE and irq_domain_is_msi_immutable() platform-msi: Add msi_remove_device_irq_domain() in platform_device_msi_free_irqs_all() genirq/msi: Rename msi_[un]lock_descs() ... 2025-05-27T15:07:32Z Linus Torvalds torvalds@linux-foundation.org 2025-05-27T15:07:32Z urn:sha1:2bd1bea5fa6aa79bc563a57919730eb809651b28 Pull irq cleanups from Thomas Gleixner: "A set of cleanups for the generic interrupt subsystem: - Consolidate on one set of functions for the interrupt domain code to get rid of pointlessly duplicated code with only marginal different semantics. - Update the documentation accordingly and consolidate the coding style of the irqdomain header" * tag 'irq-cleanups-2025-05-25' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (46 commits) irqdomain: Consolidate coding style irqdomain: Fix kernel-doc and add it to Documentation Documentation: irqdomain: Update it Documentation: irq-domain.rst: Simple improvements Documentation: irq/concepts: Minor improvements Documentation: irq/concepts: Add commas and reflow irqdomain: Improve kernel-docs of functions irqdomain: Make struct irq_domain_info variables const irqdomain: Use irq_domain_instantiate()'s return value as initializers irqdomain: Drop irq_linear_revmap() pinctrl: keembay: Switch to irq_find_mapping() irqchip/armada-370-xp: Switch to irq_find_mapping() gpu: ipu-v3: Switch to irq_find_mapping() gpio: idt3243x: Switch to irq_find_mapping() sh: Switch to irq_find_mapping() powerpc: Switch to irq_find_mapping() irqdomain: Drop irq_domain_add_*() functions powerpc: Switch irq_domain_add_nomap() to use fwnode thermal: Switch to irq_domain_create_linear() soc: Switch to irq_domain_create_*() ... 2025-05-27T15:00:46Z Linus Torvalds torvalds@linux-foundation.org 2025-05-27T15:00:46Z urn:sha1:c0f182c979cfead8fff08108a11fbd2fe885dd33 Pull irq controller updates from Thomas Gleixner: "Update for interrupt chip drivers: - Convert the generic interrupt chip to lock guards to remove copy & pasta boilerplate code and gotos. - A new driver fot the interrupt controller in the EcoNet EN751221 MIPS SoC. - Extend the SG2042-MSI driver to support the new SG2044 SoC - Updates and cleanups for the (ancient) VT8500 driver - Improve the scalability of the ARM GICV4.1 ITS driver by utilizing node local copies a VM's interrupt translation table when possible.
