Add cirrus reset handler
The vga reset handler overwrites some cirrus registers, causing rebootsto corrupt cirrus state to the point that guests can only bring up 640x480resolutions.
Fix by adding a dedicated cirrus reset handler (which calls the common vga...
KVM: Coalesced MMIO support
MMIO exits are more expensive in KVM or Xen than in QEMU because theyinvolve, at least, privilege transitions. However, MMIO writeoperations can be effectively batched if those writes do not have sideeffects.
Good examples of this include VGA pixel operations when in a planar...
do boundary check based on absolute value (Glauber Costa)
For backward operations, dstpitch and srcpitch canbe negative. This leads BLTUNSAFE macro into anoverflow, and as a result, it avoids performingoperations that are perfectly valid.
The visible effect that led to that patch was the gnome-panel...
vga optimization (Glauber Costa)
Hypervisors like KVM perform badly while doing mmio ona loop, because it'll generate an exit on each access.This is the case with VGA, which results in very badperformance.
In this patch, we map the linear frame buffer as RAM,...
move vga_io_address to VGA State (Glauber Costa)
It'll be reused later by the vga optimization.

better type checking for vga (Glauber Costa)
unsigned long is too bad of a type. Use ram_addr_t instead.
