* Greg Watson <[EMAIL PROTECTED]> [040608 15:22]:I think this is a reasonable idea, particularly your suggestion of
making linuxbios more modular. One of my main beefs with the payload
strategy is that each payload has to provide it's own set of,
potentially buggy, driver code. If we have 5 payloads then we have 5
sets of drivers that all do the same thing slightly differently. If the
drivers were modular enough so that a payload could call them directly,
then this would go a long way to addressing these concerns.
As far as I can tell the only drivers involved would be output drivers,
ie. video output and serial output. There the extensible LinuxBIOS table
could come into play. The video driver could store a pointer to the
framebuffer, the resolution and maybe even a font, to save duplicates.
Serial is only a kilobyte or so of a driver i think.
Have I forgotten something?
PCI device code and resource information should be available for payloads to use. A payload should not have to re-probe for devices on the PCI bus.
