[Qemu-devel] [PATCH 00/19] OpenPIC refactoring and MSI support v2 |

The OpenPIC implemtation has been a sad piece of code in the QEMU tree
for a long time now. It's ugly, doesn't stick to the coding style and
misses out on a few of the recent infrastructure improvements.
This patch set is a first stab at moving the OpenPIC further towards
maintainable code. It cleans up the OpenPIC/MPIC code duplication that
was in there (MPIC is just an implementation of the OpenPIC spec, so the
naming didn't make sense). It doesn't fully clean up everything yet.
While at it, this patch set also adds support for MSI(-X) to the MPC8544
variant of the OpenPIC. I have successfully tested MSI and MSI-X with
ahci and virtio-net.
Please beware that savevm support is broken after this patch set. I
have quite big doubts that saving a ppc vm works at all right now though,
so let's just leave it broken for now and replace it with a new version
that is going to be savevm based later.
v1 -> v2:
- don't overlap internal vectors on src irqs
- rename mpc8544 to fsl_mpic_20
