[Xen-devel] [PATCH 00/17] ARM: vGIC: prepare for splitting the vGIC code

[Andre Przywara <andre.przywara@xxxxxxxxxx>]

To get away from that scary xx/57 number in the new vGIC series, these
are the first few patches split off. They prepare the existing Xen code
to better observe the split between the vGIC emulation and the physical
GIC driver.
This affects the first 20 patches from the new vGIC series. Most of them
have already been ACKed. Exceptions are:
- Patch 01/57 has been merged already.
- Patch 04/57 has been dropped, the one #define left has been moved into
  patch 03/17 here. I dropped Julien's ACK because of that.
- Patch 15/57 has been dropped, we don't need it anymore in the new vGIC.
- Patches 07, 08, 09 and 14/17 were changed according to the review comments on
  patches 09, 10, 11 and 17/57, respectively.

Every patch has been compile tested on arm and arm64, also the end result
has been briefly tested with two guests on a Juno(arm64) and Midway(arm)
platform.

A branch with those patches is available at the new-vgic/prep branch at:
git://linux-arm.org/xen-ap.git

Cheers,
Andre
