After a while the right hand side of the display begins to tear and flicker to the right of objects. I have only noticed this in recent FSO builds using 2.6.28 kernels. I haven't found a reliable way to reproduce this, though each time it has occured shortly after coming out of suspend. | | The only other time I've seen this kind of tearing effect was when rotating the screen using xrandr before all the kinks were sorted out (6 months ago). | | http://www.strapp.co.uk/files/tearing.png (It isn't a bad quality image, that is how how it appears) | http://www.strapp.co.uk/files/nos.mpg (This IS a bad quality movie but you can just make out the jittering next to the house icon) | | I'm fairly certain that it isn't a hardware problem. I'd like to hear whether anyone else has seen this before.
This looks like trouble with the Glamo internal memory. There's another open bug with one guy who gets heavy noise on Glamo which is also related to internal memory communication problems. https://docs.openmoko.org/trac/ticket/2217 In both his and your cases I guess this is because your Glamo / Memory can't cope with the 89MHz memory clock we set now on 2.6.28 kernels. When I'm through with this rebase from Hell I'll add a module param to allow testing back at 80MHz, which is used on 2.6.24. There's a couple of other things changed and we can also try those on devices showing this symptom until we figure out which changes make it show up on those devices. - -Andy -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org iEYEARECAAYFAkl+BMcACgkQOjLpvpq7dMpyNACfYVq8K4XqNGkDqUoAz9RIGuAK CQ8An33HYRro6RrGiM7CE0KyyD3t9eFq =AVuV -----END PGP SIGNATURE-----
