2012-09-28iommu/amd: Add initialization routines for AMD interrupt remappingJoerg Roedel
Add the six routines required to setup interrupt remapping with the AMD IOMMU. Also put it all together into the AMD specific irq_remap_ops. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2012-09-28iommu/amd: Add slab-cache for irq remapping tablesJoerg Roedel
The irq remapping tables for the AMD IOMMU need to be aligned on a 128 byte boundary. Create a seperate slab-cache to guarantee this alignment. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2012-06-15irq/apic: Use config_enabled(CONFIG_SMP) checks to clean up ↵Suresh Siddha
irq_set_affinity() for UP Move the ->irq_set_affinity() routines out of the #ifdef CONFIG_SMP sections and use config_enabled(CONFIG_SMP) checks inside those routines. Thus making those routines simple null stubs for !CONFIG_SMP and retaining those routines with no additional runtime overhead for CONFIG_SMP kernels. Cleans up the ifdef CONFIG_SMP in and around routines related to irq_set_affinity in io_apic and irq_remapping subsystems.
