[Qemu-devel] [PATCH 00/23] VGA cleanup

[Juan Quintela]

This patch:
- cleans the differences between VGAState/VGACommon state
- moves vga pci, isa, isa-mm out of vga.c (cirrus and blizzar uses
  VGA common state).
- Cleans all the cirrus_hook_* stuff is something that don't look like a hook :)

I would want this bits morged/reviewed before going the rest of the cleanup:

Todo:
- vga_ioport_read/write and cirrus_vga_ioport_read/write are almost identical
  after this series of changes.  Creating read/write() callbacks for
  sr/gr/cr/palette.  Should put us there.  The cirrus ones were the difficult 
ones,
  the vga ones are trivial.
- CONFIG_VBE_BOCHS code.  This code is only used by vga std (pci + isa).  
Neither
  cirrus/blizzard/isa-mm uses it.  It should be moved out of vga.c, vga-std.c?, 
and
  then used by vga-isa and vga-pci?
- vmware_vga: it uses vga as embeded, but it don't save its state, I am not sure
  if it wants/need VBE_BOCHS, ....  I haven't looked at vmware_vga too much, 
just
  to vga and cirrus_vga.

Comments?

Later, Juan.


Juan Quintela (23):
  vga: remove useless cast from void *
  cirrus_vga: prefix vga_ioport_{read,write} with cirrus
  vga: export vga_ioport_{read,write}
  vga: split vga_{load,save} into pci and common parts
  vga: split pci bits into vga-pci.c
  vga: split isa bits inco vga-isa.c
  vga: export vga_mem_{read,write}
  vga: split vga-isa-mm.o
  vga and cirrus_vga: create vga_ioport_invalid() and use it everywhere
  cirrus_vga: Add a VGACommonState local var to
    cirrus_vga_ioport_{read,write}
  vga: change tabs to spaces
  cirrus_vga: make cirrus_read_hidden_dac() return its result
  vga and cirrus_vga: substitute switch for equivalent assigntment
  vga: Rename last VGAState occurrences to VGACommonState
  cirrus_vga: rename cirrus_hook_read_sr() cirrus_vga_read_sr()
