[Linux-fbdev-devel] EDID -> var

[Ani J. <aj...@sh...>]

Attatched is a portable kernel edid parser I've put together recently.
This converts an EDID mode (first one only by  default)
into a fb_var_screenfino mode.

This is a portable method because its up to the driver to get the EDID
from its various methods (DPMI, OpenFirmware device node, DDC/i2c), the
driver can then use:

int parse_edid(unsigned char *edid, fb_var_screeninfo *var);

which will parse and convert the EDID's mode into var.

This adds another layer for a "valid" mode to be used, ie:
1) use user's argument (either modedb or driver dependent modeline)
2) use EDID
3) use default mode


This is ofcourse only useful if the EDID is available but this shouldn't
be a problem with many of todays boards.


Comments appreciated,
