* irq/irqdomain-locking: : . : irqdomain locking overhaul courtesy of Johan Hovold. : : From the cover letter: : : "Parallel probing (e.g. due to asynchronous probing) of devices that : share interrupts can currently result in two mappings for the same : hardware interrupt to be created. : : This series fixes this mapping race and reworks the irqdomain locking so : that in the end the global irq_domain_mutex is only used for managing : the likewise global irq_domain_list, while domain operations (e.g. IRQ : allocations) use per-domain (hierarchy) locking." : . irqdomain: Switch to per-domain locking irqchip/mvebu-odmi: Use irq_domain_create_hierarchy() irqchip/loongson-pch-msi: Use irq_domain_create_hierarchy() irqchip/gic-v3-mbi: Use irq_domain_create_hierarchy() irqchip/gic-v3-its: Use irq_domain_create_hierarchy() irqchip/gic-v2m: Use irq_domain_create_hierarchy() irqchip/alpine-msi: Use irq_domain_add_hierarchy() x86/uv: Use irq_domain_create_hierarchy() x86/ioapic: Use irq_domain_create_hierarchy() irqdomain: Clean up irq_domain_push/pop_irq() irqdomain: Drop leftover brackets irqdomain: Drop dead domain-name assignment irqdomain: Drop revmap mutex irqdomain: Fix domain registration race irqdomain: Fix mapping-creation race irqdomain: Refactor __irq_domain_alloc_irqs() irqdomain: Look for existing mapping only once irqdomain: Drop bogus fwspec-mapping error handling irqdomain: Fix disassociation race irqdomain: Fix association race Signed-off-by: Marc Zyngier <maz@kernel.org> |
