[R300] radeon 9800 lockup : guilty reg list

[Jerome G. <j.g...@gm...>]

Hi,

After launching several times flgrx and dumping the reg
and diffing against what was reg with r300 here is the list
of reg that have always on my card (RV350NJ) the same
value (for the same screen resolution). I think that one
of the unknown reg maybe a group of them are the key
one but anyway i wasn't able to write to most of this reg.
They may are read only thus i tried writing random things
in register near them but i only succeed to lockup  the card
and the reg i was interested in didn't change.

Thus if anyone got any info on any of this reg, some must
be in old radeon spec but i haven't this specs and don't
understand from their name what they do (not all :)).

Maybe dumping value that fglrx set in this reg on other
card could be usefull....

For the know reg i have put their name either taken
from xorg reg list of from fb radeon one. The second
value is what fglrx set in them r300 value is different.
