[Qemu-devel] [PATCH v2 00/23] Rework i8259 and PC interrupt models

[Jan Kiszka]

Highlights of this series:
 - generic i8259, now part of hwlib
 - qdev conversion of i8259
 - fix for i8259 poll mode (and removal of PREP hack)

The refactoring will also be important to instantiate i8259-kvm devices
for in-kernel irqchip acceleration one day.

Changes in v2:
 - kept PIC irq state update after reset but clarified why this 
   required and only valid here
 - additional fix: Clear ELCR on reset
 - included already posted updates of patch 22 and 23
