iommu/vt-d: Relocate struct/function declarations to its header files

2018-09-25T12:33:43+00:00

To reuse the static functions and the struct declarations, move them to corresponding header files and export the needed functions.

x86: irq_remapping: Move irq remapping mode enum

2018-07-06T12:43:47+00:00

The enum is currently defined in Intel-specific DMAR header file, but it is also used by APIC common code. Therefore, move it to a more appropriate interrupt-remapping common header file. This will also be used by subsequent patches. Cc: Thomas Gleixner Cc: Ingo Molnar Cc: Joerg Roedel Signed-off-by: Suravee Suthikulpanit Signed-off-by: Joerg Roedel

x86/msi: Provide new iommu irqdomain interface

2017-06-22T16:21:10+00:00

Provide a new interface for creating the iommu remapping domains, so that the caller can supply a name and a id in order to create named irqdomains.

irq_remapping: move structs outside #ifdef

2015-10-01T13:06:42+00:00

This is friendlier to clients of the code, who are going to prepare vcpu_data structs unconditionally, even if CONFIG_IRQ_REMAP is not defined. Reviewed-by: Thomas Gleixner Signed-off-by: Paolo Bonzini

iommu, x86: Provide irq_remapping_cap() interface

2015-06-12T09:33:52+00:00

Add a new interface irq_remapping_cap() to detect whether irq remapping supports new features, such as VT-d Posted-Interrupts. Export the function, so that KVM code can check this and use this mechanism properly.
