[Qemu-devel] [PATCH v3 0/5] vGICv3 support

[Pavel Fedin <p.fedin@samsung.com>]

This series introduces support for GICv3 by KVM. Software emulation is
currently not supported.

Differences from v2:
- Removed some urelated and unnecessary changes from virt machine,
  occasionally slipped in; some of them caused qemu to crash on ARM32.
- Fixed build for ARM32; vGICv3 code requires definitions which are
  present only in ARM64 kernel

Differences from v1:
- Base class included, taken from the series by Shlomo Pongratz:
  http://lists.nongnu.org/archive/html/qemu-devel/2015-06/msg01512.html
  The code is refactored as little as possible in order to simplify
  further addition of software emulation:
  - Minor fixes in code style and comments, according to old reviews
  - Removed REV_V3 definition because it's currently not used, and it does
    not add any meaning to number 3.
  - Removed reserved regions for MBI and ITS (except for 'virt' machine
    memory map). These should go to separate classes when implemented.
- Improved commit messages
- vGIC patches restructured
- Use 'gicversion' option instead of virt-v3 machine

Pavel Fedin (4):
  Extract some reusable vGIC code
  Introduce irqchip type specification for KVM
  Initial implementation of vGICv3
  Add gicversion option to virt machine

Shlomo Pongratz (1):
  Implement GIC-500 base class
