info or dp must not be right. I'll try some more tomorrow.
By looking at the code, it appears that leo has no property named
"linebytes" which means that par->fbsize is probably 0. I will
verify this tonight when I get a chance.
Bearing in mind that I am a long way down the ladder as far as
understanding kernel driver modules and the Sun architecture goes, but
adding more debugging code I see
[MarkMLl] In leo_fixup_var_rgb()
[MarkMLl] of_getintprop_default(linebytes, 1152) returned 1152
[MarkMLl] fbsize 1040384
[MarkMLl] In leo_init_wids()
i.e. I think it's being supplied with a plausible default. Can anybody
say whether that result is sane?
I've been trying to compare 2.4 and 2.6 drivers but so far have not
really found enough similarities to be able to work out the relevant
differences.
This patch gets the driver loading and not crashing but it also doesn't
work.
I just get a blank screen so there is still something else wrong.
Sun will be releasing leo documentation soon:
http://wikis.sun.com/display/FOSSdocs/Home
so I hope that helps in figuring out what else is wrong.
