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
Thanks for noting!
This means the TILER should somehow be made OMAP5 (Pyra) only or fixed to gracefully handle OMAP3.
BR and thanks, Nikolaus
