[Xen-devel] [PATCH v4 00/17] Add ITS support

[vijay.kilari@xxxxxxxxx]

From: Vijaya Kumar K <Vijaya.Kumar@xxxxxxxxxxxxxxxxxx>

This is based on DraftF version
http://xenbits.xen.org/people/ianc/vits/draftG.pdf

Following major features are supported
 - GICv3 ITS support for arm64 platform
 - Only Dom0 is supported. For DomU pci passthrough feature
   is required.

Basic boot is tested with single ITS node by adding 
and assigning devices from platform initialization.

Changes in v4:
  - Patch for rate limiting of error message is removed.
  - Patch #4 and #5 in v3 is merged
  - Merged #13 and #16 as one patch
  - hw_irq_controller is implemented for LPIs
  - GITS and GICR emulation for LPIs in separate patches
  - Removed build functions for ITS command in physical ITS driver
  - Added new patch to add and assign devices from platform file
  - Enable compilation of vits and pits driver in separate patch
  - Replace msi-parent property in all pci dt nodes to single
    ITS node generated by Xen for Dom0
