Patch attached. I guess this would remain as a Mageia specific patch as
the wanted behavior is dependant on how the distribution handles driver
switching etc...
Speaking of driver switching...
Is it possible to detect missing radeon firmware in initrd in early
boot, and then switch to loading radeon with modeset=0 ?
Seems doable (if a bit hacky), but unfortunately new radeon cards (at
least cayman/northern islands) do not work without KMS at all (while
slightly older cards like Evergreen mostly work but without any kind of
2d/3d acceleration).
Yeah, I started thinking about those too after my post...
This also means that X server will fail to start since it doesn't
fallback to autodetection (and therefore vesa) when the card is
explicitely listed in xorg.conf.
Not quite sure what is the best way forward.
Hm, so we would need a split in detection for nonkms capable cards
and the rest...
or take the easy way out and boot everyone on vesa until radeon firmware
is available...
BTW, shouldn't we regenerate initrds when installing radeon-firmware for
the first time?
Yeah, I've been thinking the same, but haven't gotten around to doing it
yet.
and what about nvidia* and fglrx, should they do the same ?
and for a dkms related issue, I've also been thinking we whould
trigger dkms rebuild on kernel install to save time on next bootup.
