iommu/vt-d: Refine the interfaces to create IRQ for DMAR unit

2015-04-24T13:36:49+00:00

Refine the interfaces to create IRQ for DMAR unit. It's a preparation for converting DMAR IRQ to hierarchical irqdomain on x86. It also moves dmar_alloc_hwirq()/dmar_free_hwirq() from irq_remapping.h to dmar.h. They are not irq_remapping specific.

ia64: Use for_each_cpu_and() and cpumask_any_and() instead of temp var.

2015-03-05T03:07:01+00:00

Just a bit of manual neatening, before spatch cleans the rest. Signed-off-by: Rusty Russell Cc: Tony Luck Cc: Fenghua Yu Cc: linux-ia64@vger.kernel.org

PCI/MSI: Rename mask/unmask_msi_irq treewide

2014-11-23T12:01:45+00:00

The PCI/MSI irq chip callbacks mask/unmask_msi_irq have been renamed to pci_msi_mask/unmask_irq to mark them PCI specific. Rename all usage sites. The conversion helper functions are kept around to avoid conflicts in next and will be removed after merging into mainline. Coccinelle assisted conversion. No functional change.

PCI/MSI: Use __get_cached_msi_msg() instead of get_cached_msi_msg()

2014-10-01T18:21:23+00:00

Both callers of get_cached_msi_msg() start with a struct irq_data pointer, look up the corresponding IRQ number, and pass it to get_cached_msi_msg(), which then uses irq_get_irq_data() to look up the struct irq_data again to call __get_cached_msi_msg(). Since we already have the struct irq_data, call __get_cached_msi_msg() directly and skip the lookup work done by get_cached_msi_msg(). No functional change.

ia64: Validate online cpus in irq_set_affinity() callbacks

2014-03-12T12:07:40+00:00

The [user space] interface does not filter out offline cpus. It merily guarantees that the mask contains at least one online cpu. So the selector in the irq chip implementation needs to make sure to pick only an online cpu because otherwise: Offline Core 1 Set affinity to 0xe (is valid due to online mask 0xd) cpumask_first will pick core 1, which is offline Signed-off-by: Thomas Gleixner Cc: Peter Zijlstra Cc: Tony Luck Cc: Fenghua Yu Cc: ia64 Link: http://lkml.kernel.org/r/20140304203100.650414633@linutronix.de Signed-off-by: Thomas Gleixner

arch/ia64: remove references to cpu_*_map

2012-03-29T00:14:36+00:00

This was marked as obsolete for quite a while now.. Now it is time to remove it altogether. And while doing this, get rid of first_cpu() as well. Also, remove the redundant setting of cpu_online_mask in smp_prepare_cpus() because the generic code would have already set cpu 0 in cpu_online_mask. Reported-by: Tony Luck Signed-off-by: Srivatsa S.

iommu: Rename the DMAR and INTR_REMAP config options

2011-09-21T08:22:03+00:00

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.
