[Qemu-devel] [PATCH v3 0/9] Move interrupts from spapr to xics

[Alexey Kardashevskiy]

This moves interrupts allocation business from SPAPR to XICS
and makes use of it.

Changes:
v3:
* replaces static array of descriptors in SPAPR PHB with GHashTable
* implements migration of hash table via temporary array

v2:
* s/server/source/
* fixed typos, code style, added an assert
* added patch for spapr_pci for better IRQ reuse for MSI/MSIX

There is just one source at the moment. We might create one
per PHB and one per VIO device or VIO bus but I do not see any
immediate profit from it.



Juan, Peter, you are cc-ed because 8/9 introduces new 
VMSTATE_STRUCT_VARRAY_ALLOC
and 9/9 makes use of it and checkpatch.pl thinks you might be right people
to get opinion about this from.


Please comment. Thanks!
