List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , To: qemu-devel@nongnu.org, imammedo@redhat.com, mst@redhat.com, pbonzini@redhat.com Cc: guz.fnst@cn.fujitsu.com, hutao@cn.fujitsu.com, isimatu.yasuaki@jp.fujitsu.com, zhugh.fnst@cn.fujitsu.com, tangchen@cn.fujitsu.com Memory and CPU hot unplug are both asynchronize procedures. When the unplug operation happens, unplug request cb is called first. And when ghest OS finished handling unplug, unplug cb will be called to do the real removal of device. They both need pc-machine, piix4 and ich9 unplug and unplug request cb. So this patch set introduces these commom functions as part1, and memory and CPU hot-unplug will come soon as part 2 and 3. This patch-set is based on QEmu 2.2 Tang Chen (5): acpi, pc: Add hotunplug request cb for pc machine. acpi, ich9: Add hotunplug request cb for ich9. acpi, pc: Add unplug cb for pc machine. acpi, ich9: Add unplug cb for ich9. acpi, piix4: Add unplug cb for piix4. hw/acpi/ich9.c | 14 ++++++++++++++ hw/acpi/piix4.c | 8 ++++++++ hw/i386/pc.c | 16 ++++++++++++++++ hw/isa/lpc_ich9.c | 14 ++++++++++++-- include/hw/acpi/ich9.h | 4 ++++ 5 files changed, 54 insertions(+), 2 deletions(-) -- 1.8.4.2
