From 34e71e4cbb8eb467dbcfb3afbd2b95ff2b08f482 Mon Sep 17 00:00:00 2001 From: Yuriy Kolerov Date: Tue, 8 Nov 2016 10:08:31 +0300 Subject: ARC: IRQ: Do not use hwirq as virq and vice versa This came up when reviewing code to address missing IRQ affinity setting in AXS103 platform and/or implementing hierarchical IRQ domains - smp_ipi_irq_setup() callers pass hwirq but in turn calls request_percpu_irq() which expects a linux virq. So invoke irq_find_mapping() to do the conversion (also explicitify this in code by renaming the args appropriately) - idu_of_init()/idu_cascade_isr() were similarly using linux virq where hwirq is expected, so do the conversion using irqd_to_hwirq() helper Signed-off-by: Yuriy Kolerov [vgupta: made changelog a bit concise a bit] Signed-off-by: Vineet Gupta --- arch/arc/include/asm/smp.h | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'arch/arc/include') diff --git a/arch/arc/include/asm/smp.h b/arch/arc/include/asm/smp.h index 89fdd1b0a76e..0861007d9ef3 100644 --- a/arch/arc/include/asm/smp.h +++ b/arch/arc/include/asm/smp.h @@ -37,9 +37,9 @@ extern const char *arc_platform_smp_cpuinfo(void); * API expected BY platform smp code (FROM arch smp code) * * smp_ipi_irq_setup: - * Takes @cpu and @irq to which the arch-common ISR is hooked up + * Takes @cpu and @hwirq to which the arch-common ISR is hooked up */ -extern int smp_ipi_irq_setup(int cpu, int irq); +extern int smp_ipi_irq_setup(int cpu, irq_hw_number_t hwirq); /* * struct plat_smp_ops - SMP callbacks provided by platform to ARC SMP -- cgit v1.2.3
