Re: Seg fault on any FB write (Epson S1D13A04onColdfire running 2.6.25)

The 2.6.10 driver is considerably different. There's no platform device
structure. I tried taking the 2.6.10 forward to the 2.6.25 kernel but
found so many differences I thought getting the 2.6.25 driver working
would be easier.

Again, I've never made a patch for it. I've attached the actual driver
code here.

Not to make excuses (but here I go) this is the first foray I've made into
the kernel in any real way so I'm still figuring out the right way to do
things (after I get them to work at all).

Thanks again.

Sorry, I was hacking around just to get something to work. If you look
at
the two side by side you'll see that I've not changed that much. The
changes are mostly just plugging in my specific info for the panel I'm
using.

I've not worked with patches much so I'll have to figure out how to do
that.

Perhaps you should include the old patch to 2.6.10 since
we know that worked and take it from there? In theory
all you should need are the basic mappings and
perhaps and reg init structure.

I'm not sure if this is correct - two drivers mapped the same region
twice !?
Maybe the experts will shed some light on this..

I haven't took a long look at your driver, but here is our driver for
S13706FB that
we use on our embedded platform. Hope it helps.

Any chance of getting a patch against s1d13xxxfb?
