We have two flavours of IPI implementations: IRQ_DOMAIN_FLAG_IPI_PER_CPU: Each CPU has its own virq and hwirq IRQ_DOMAIN_FLAG_IPI_SINGLE : A single virq and hwirq for all CPUs Signed-off-by: Qais Yousef <qais.yousef@xxxxxxxxxx> Cc: <jason@xxxxxxxxxxxxxx> Cc: <marc.zyngier@xxxxxxx> Cc: <jiang.liu@xxxxxxxxxxxxxxx> Cc: <ralf@xxxxxxxxxxxxxx> Cc: <linux-mips@xxxxxxxxxxxxxx> Cc: <lisa.parratt@xxxxxxxxxx> Cc: Qais Yousef <qsyousef@xxxxxxxxx> Link: http://lkml.kernel.org/r/1449580830-23652-2-git-send-email-qais.yousef@xxxxxxxxxx Signed-off-by: Thomas Gleixner <tglx@xxxxxxxxxxxxx> --- include/linux/irqdomain.h | 37 +++++++++++++++++++++++++++++++++++++ 1 file changed, 37 insertions(+) diff --git a/include/linux/irqdomain.h b/include/linux/irqdomain.h index 04579d9..9bb0a9c 100644 --- a/include/linux/irqdomain.h +++ b/include/linux/irqdomain.h @@ -172,6 +172,12 @@ enum { /* Core calls alloc/free recursive through the domain hierarchy. */ IRQ_DOMAIN_FLAG_AUTO_RECURSIVE = (1 << 1), + /* Irq domain is an IPI domain with virq per cpu */ + IRQ_DOMAIN_FLAG_IPI_PER_CPU = (1 << 2), + + /* Irq domain is an IPI domain with single virq */ + IRQ_DOMAIN_FLAG_IPI_SINGLE = (1 << 3), + /* * Flags starting from IRQ_DOMAIN_FLAG_NONCORE are reserved * for implementation specific purposes and ignored by the @@ -400,6 +406,22 @@ static inline bool irq_domain_is_hierarchy(struct irq_domain *domain) { return domain->flags & IRQ_DOMAIN_FLAG_HIERARCHY; } + +static inline bool irq_domain_is_ipi(struct irq_domain *domain) +{ + return domain->flags & + (IRQ_DOMAIN_FLAG_IPI_PER_CPU | IRQ_DOMAIN_FLAG_IPI_SINGLE); +} + +static inline bool irq_domain_is_ipi_per_cpu(struct irq_domain *domain) +{ + return domain->flags & IRQ_DOMAIN_FLAG_IPI_PER_CPU; +} + +static inline bool irq_domain_is_ipi_single(struct irq_domain *domain) +{ + return domain->flags & IRQ_DOMAIN_FLAG_IPI_SINGLE; +} #else /* CONFIG_IRQ_DOMAIN_HIERARCHY */ static inline void irq_domain_activate_irq(struct irq_data *data) { } static inline void irq_domain_deactivate_irq(struct irq_data *data) { } @@ -413,6 +435,21 @@ static inline bool irq_domain_is_hierarchy(struct irq_domain *domain) { return false; } + +static inline bool irq_domain_is_ipi(struct irq_domain *domain) +{ + return false; +} + +static inline bool irq_domain_is_ipi_per_cpu(struct irq_domain *domain) +{ + return false; +} + +static inline bool irq_domain_is_ipi_single(struct irq_domain *domain) +{ + return false; +} #endif /* CONFIG_IRQ_DOMAIN_HIERARCHY */ #else /* CONFIG_IRQ_DOMAIN */
