[Letux-kernel] fb tiler considered harmful

[Andreas Kemnade]

Hi,

As I wanted to test the new alsa routing patches, there was one problem:
No Framebuffer output, 

Suspicious pieces in console log:
[    2.556823] omapdrm omapdrm.0: DMM not available, disable DMM support
[    2.565490] [drm] Supports vblank timestamp caching Rev 2 (21.10.2013).
[    2.565551] [drm] No driver support for vblank timestamp query.
[    2.566528] omapdrm omapdrm.0: Tiled buffers require DMM
[    2.567382] omapdrm omapdrm.0: failed to allocate buffer object
[    2.567718] omapdrm omapdrm.0: omap_fbdev_init failed
[    2.567932] [drm] Initialized omapdrm 1.0.0 20110917 on minor 0

I have to add that I have compiled the framebuffer statically and using it
for console output.

After reverting the following branches, the framebuffer worked again.

extern/mvduin/patch/tiler-buf-dumb
extern/mvduin/patch/tiler-fbdev

Regards,
Andreas
