Hi,

QEMU provides the global '-g' CLI option:

$ qemu-system-foo --help

  -g WxH[xDEPTH]  Set the initial graphical resolution and depth

This option is used to pass resolution/depth information to guest
firmwares in the machines defined in the following files:

  hw/ppc/mac_newworld.c
  hw/ppc/mac_oldworld.c
  hw/ppc/prep.c
  hw/ppc/spapr.c
  hw/sparc/sun4m.c
  hw/sparc64/sun4u.c

Examples:

- hw/ppc/spapr.c:1102:

  _FDT(fdt_setprop_cell(fdt, c, "qemu,graphic-width", graphic_width));

- hw/sparc64/sun4u.c:716:

  fw_cfg_add_i16(fw_cfg, FW_CFG_SPARC64_WIDTH, graphic_width);


Obviously we have default values, which are different per architecture!
Clearly these ought to be machine properties.


It is also used to set TYPE_NUBUS_MACFB properties in hw/m68k/q800.c.
Here i suppose we could directly use '-global nubus-macfb.width=value'
etc. although I'm not sure it is the recommended way.

Should we start deprecating '-g' as a whole?

Regards,

Phil.
