[Letux-kernel] framebuffer woes again in 4.15-rc

[Andreas Kemnade]

Hi,

there is again a mvduin/patch/tiler-fbdev-v3 in the letux kernel.
And again framebuffer applications do not work sane. Mmapping /dev/fb0 and
zeroing that causes trouble (Bus error or hangs) on the gta04.
Just text on framebuffer is ok (fixed by my patch)

If I understand it correctly:
 That patch series is the best we have to have proper rotation on the Pyra
 so that is why it is in altough the author knows that it breaks things
 (and probably also what) and therefore did not recommend to apply it
 anywhere.

But for qtmoko we need a working framebuffer. So we need a solution.

But as the patch series contains as far as I can remember wrong approaches
it does not make sense to further hack-fix it for me. And finding out
bugs which somebody else knows and understands seems to be duplicated effort.

Please correct me if I am wrong.

Regards,
Andreas
