From e420dfb40c453a9760b86c7f338052bdb4dfa755 Mon Sep 17 00:00:00 2001 From: Yinghai Lu Date: Tue, 19 Aug 2008 20:50:21 -0700 Subject: x86: put irq_2_iommu pointer into irq_desc when CONFIG_HAVE_SPARSE_IRQ preallocate some irq_2_iommu entries, and use get_one_free_irq_2_iomm to get new one and link to irq_desc if needed. else will use dyn_array or static array. v2: <= nr_irqs fix Signed-off-by: Yinghai Lu Signed-off-by: Ingo Molnar --- include/linux/irq.h | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'include') diff --git a/include/linux/irq.h b/include/linux/irq.h index d5749852ee6..788d5a35a58 100644 --- a/include/linux/irq.h +++ b/include/linux/irq.h @@ -128,6 +128,7 @@ struct irq_chip { }; struct timer_rand_state; +struct irq_2_iommu; /** * struct irq_desc - interrupt descriptor * @@ -162,6 +163,9 @@ struct irq_desc { unsigned int *kstat_irqs; #else unsigned int kstat_irqs[NR_CPUS]; +#endif +#if defined(CONFIG_INTR_REMAP) && defined(CONFIG_HAVE_SPARSE_IRQ) + struct irq_2_iommu *irq_2_iommu; #endif irq_flow_handler_t handle_irq; struct irq_chip *chip; -- cgit v1.2.3
