According to Mitch Bradley, switching away from VSA saved ~10 seconds during early bootup.
This makes me think there was something pretty much broken. The GX1 I have here does not even need 10s before it starts loading the OS, and it has VSA in place (not LinuxBIOS though)
I may have misunderstood his mail back then. However, switching from LinuxBIOS(+)VSA to OFW(-)VSA reduced time from poweron to active display by ~13 seconds.
I'd like to split the VSA into "useful" chunks and "unneeded" chunks. VGA/sound emulation is now unnecessary since Linux has drivers for the native hardware. Bootloaders might want VGA, though. However, PCI emulation makes some things much easier IMO.
So do distributions. Loading a geodefb in a non-embedded platform is most likely not going to happen, unless someone tunes the system.
Can we detect that something uses VGA and enable the VGA VSA on demand?
