[Qemu-devel] [RfC PATCH 0/2] new screendump qmp command

[Gerd Hoffmann]

  Hi,

Just a rough + incomplete draft for now, to show the idea.

Series adds a new screendump qmp command.  This does (a) allow
to specify the device we want dump from, (b) does the actual
image writing in a bottom half and (c) sends a qmp event when
(not done yet, just a comment for now).

It also adds a graphics_hw_update() variant with completion
notification (by calling a bottom half).

qxl then could stick the pointer to the notification BH into the
QXLCookie struct and schedule the BH when spice server finished
updating the screen.
