[Qemu-devel] [PATCH v14 0/4] pvevent device to deal with guest panic event

[Hu Tao]

This series introduces a new simulated device, pvevent, to notify
qemu when guest panic event happens.

Along with this series, there are two patches to add seabios ACPI
driver and kernel ACPI driver for the device, respectively.

TODO: make the io port used by pvevent device configurable.

Tested with:

  - qemu(kvm)
  - qemu(tcg)
  - piix
  - q35

Changes from v13:

  - communicate the io port with guest by ACPI, instead of hardcoding it 
(Marcelo)
  - panic event action is always 'pause' (Paolo)
  - not kvm-specific (Gleb)
  - make the device target-independent (Paolo)
  - no runstate save/load(will be a seperate patch) (Paolo)
  - support q35 (Gleb)
  - doc about qmp event (Eric)
  - doc about pvevent device (Paolo)
 
v13: http://lists.nongnu.org/archive/html/qemu-devel/2013-02/msg05361.html
