7200/platinum with 2.2.7 kernel...

[Mark Abene]

I don't know if anyone has noticed, but as of 2.2.7 (which is what I just 
checked), the platinum video driver still has the annoying line about three
inches above the bottom of the screen, from the middle to the right edge.
This is in modes 19 and 20 at 16bpp, (with the "scale" hack to fix the 
colormap).  The line was there without the scale-hack, so that's not it.
I was about to start digging in platinumfb.c to see what the deal is (it's
changed quite a bit), and unfortunately the first thing I noticed was that
my name was removed from the opening comments(!).  Rather uncool.  That driver
and it's header file are still chock-full of a lot of my code, and even my
comments.  I spent a good deal of time helping Paul M. get that driver working,
and am confused as to why its current maintainer saw fit to expunge my name.
Besides which, it looks like a few things were broken when it was "rewritten"
for fbconsole-style support, which makes me uneasy, since it originally worked
fine, and as expected.  I know there's a lot of focus on the G3 machines now,
but I'm sure there're still a decent number of us 7200/8200/PT120 users out
there who give a damn.  I'll look into the current problems which I'm seeing
on the list, and I'd welcome anyone's input who's messed with the driver in
its current state.  Remember, 601 users are people too.

Thanks,
-Mark

Hmm, then it was probably not there in the old platinum.c file or I missed to
copy it. But the comments at the top are correct, platinumfb is based on the
controlfb driver, not on the old platinum.c. I only ripped out and modified the
hardware info from platinum.c. And why didn't you stand up ~1 year ago, when
there was lot's of discussion on the lists about the platinumfb and controlfb
drivers? Dan and I could have need help back then.

I'm still on my 7200/75 too :-), I just switched a ATI Xclaim3D, cause it's
cheaper to get such a card than to upgrade videomem. That explains why 16bit
and higher modes possibly don't work correctly, it's simply because I can only
test with 1MB on platinunm.

I know only about 3 problems right now, the
color scaling, a typo in the invalidate_cache macro, it should
use dcbf instead of dcbi. Both I haven't forwarded yet to Geert.
The other one is that 832*624*16 won't work with 1MB videomem, cause I had to
align the framebuffer on a 4K boundary.

 Feel free to fix platinumfb as you like, including the copyright. In
fact I would happily hand over "maintainership" to you, as I currently don't use
platinum anymore, except for testing. BTW, what did you test? console, Xpmac or
FBDev?

Franz.
