2013-01-28x86, irq: Move irq_remapped out of x86 core codeJoerg Roedel1-10/+0
The irq_remapped function is only used in IOMMU code after the last patch. So move its definition there too. Signed-off-by: Joerg Roedel <joro@8bytes.org> Acked-by: Sebastian Andrzej Siewior <sebastian@breakpoint.cc> Reviewed-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>
2013-01-28x86, irq: Introduce setup_remapped_irq()Joerg Roedel1-0/+9
This function does irq-remapping specific interrupt setup like modifying the chip defaults. Signed-off-by: Joerg Roedel <joro@8bytes.org> Acked-by: Sebastian Andrzej Siewior <sebastian@breakpoint.cc> Reviewed-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>
2013-01-28x86, io-apic: Move CONFIG_IRQ_REMAP code out of x86 coreJoerg Roedel1-0/+17
Move all the code to either to the header file asm/irq_remapping.h or to drivers/iommu/. Signed-off-by: Joerg Roedel <joro@8bytes.org> Acked-by: Sebastian Andrzej Siewior <sebastian@breakpoint.cc> Reviewed-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>

2013-01-28x86, io_apic: Introduce set_affinity function pointerJoerg Roedel1-9/+0
With interrupt remapping a special function is used to change the affinity of an IO-APIC interrupt. Abstract this with a function pointer.

2011-09-21iommu: Rename the DMAR and INTR_REMAP config optionsSuresh Siddha1-1/+1
Change the CONFIG_DMAR to CONFIG_INTEL_IOMMU to be consistent with the other IOMMU options. Rename the CONFIG_INTR_REMAP to CONFIG_IRQ_REMAP to match the irq subsystem name. And define the CONFIG_DMAR_TABLE for the common ACPI DMAR routines shared by both CONFIG_INTEL_IOMMU and CONFIG_IRQ_REMAP.

2010-10-12x86: Speed up the irq_remapped check in hot pathesThomas Gleixner1-0/+8
irq_2_iommu is in struct irq_cfg, so we can do the irq_remapped check based on irq_cfg instead of going through a lookup function. That's especially interesting in the eoi_ioapic_irq() hotpath.
