Who should do the diff'ing to determine valid modes? The list of legal monitor modes might be from EDID or the fbmode database. Should sysfs have one entry for legal board modes and one for legal monitor modes? Or should it just have a single entry for legal combos? --- Benjamin Herrenschmidt wrote: > On Thu, 2003-08-21 at 22:51, Jon Smirl wrote: > > Is GregKH designing the EDID thorough sysfs scheme?
