+
+QEMU Standard VGA
+=================
+
+Exists in two variants, for isa and pci.
+
+command line switches:
+ -vga std [ picks isa for -M isapc, otherwise pci ]
+ -device VGA [ pci variant ]
+ -device isa-vga [ isa variant ]
+
+
+PCI spec
+--------
+
+Applies to the pci variant only for obvious reasons.
+
+PCI ID: 1234:1111
+
+PCI Region 0:
+ Framebuffer memory, 16 MB in size (by default).
+ Size is tunable via vga_mem_mb property.
+
+PCI Region 1:
+ Reserved (so we have the option to make the framebuffer bar 64bit).
+
+PCI Region 2:
+ MMIO bar, 4096 bytes in size (qemu 1.3+)
+
+PCI ROM Region:
+ Holds the vgabios (qemu 0.14+).
+
+
+IO ports used
+-------------
+
+03c0 - 03df : standard vga ports
+01ce : bochs vbe interface index port
+01cf : bochs vbe interface data port
+
+
+Memory regions used
+-------------------
+
+0xe0000000 : Framebuffer memory, isa variant only.
+
+The pci variant used to mirror the framebuffer bar here, qemu 0.14+
+stops doing that (except when in -M pc-$old compat mode).
+
+
+MMIO area spec
+--------------
+
+Likewise applies to the pci variant only for obvious reasons.
+
+0000 - 03ff : reserved, for possible virtio extension.
+0400 - 041f : vga ioports (0x3c0 -> 0x3df), remapped 1:1.
+ word access is supported, bytes are written
+ in little endia order (aka index port first),
+ so indexed registers can be updated with a
+ single mmio write (and thus only one vmexit).
+0500 - 0515 : bochs dispi interface registers, mapped flat
+ without index/data ports. Use (index << 1)
+ as offset for (16bit) register access.
