[Qemu-devel] [RESEND PATCH v3 0/8] QEmu memory hot unplug support.


From: Tang Chen
Subject: [Qemu-devel] [RESEND PATCH v3 0/8] QEmu memory hot unplug support.
Date: Wed, 27 Aug 2014 16:08:31 +0800

This patch-set implements memory hot-remove for QEmu.

Approach: QEmu sets GPE status bit, then triggers SCI to notify guest os.
Guest os checks device status, and free memory resource if possible,
then generate OST. Finally, qemu handles OST events to free dimm device.

Change log v2 -> v3:
1. Divide the large patch into 7 small patches. 
   (patch 1, 3~8)
2. Add new patch 2/8, implementing memory hot-remove for ich9.
3. Sanitize ACPI hardware implement code in patch 6/8.

Hu Tao (6):
  acpi, piix4: Add memory hot unplug support for piix4.
  pc: Add memory hot unplug support for pc machine.
  qdev: Add memory hot unplug support for bus-less devices.
  pc-dimm: Add pc_dimm_unrealize() for memory hot unplug support.
