Re: per-fb mmap for platinumfb and valkyriefb in 2.4 (and 2.2)

On  14 Sep, this message from Martin Costabel echoed through cyberspace:

Anyway, here it is for both 2.2 and 2.4. Note that to compile on 2.2,
you need my controlfb patch implementing mmap as well, since without it,
this one won't compile (get it on sourceforge).

Tried it for valkyriefb: Doesn't work. It works in console mode, where
it actually feels like it is scrolling fast, but starting X gives an
immediate system freeze. I tried it twice, but now I'll go to bed.

Have fun!

Not much fun in hard rebooting and watching 15 minutes of fsck.

Sorry about that.... hope you slept well nevertheless ;-)

Can you have a look and see what might be wrong? Ill do the same,
hopefully tonight, but no guarantee...

A quick look shows that valkyrie has a single memory region, with the
framebuffer, the registers and the colormap all within the same region.
That might blow up the logic within valkyrie_mmap() to defferentiate between
framebuffer and mmio.

Thanks

Michel
