Someone lately posted a message detailing the problem (either here or on debian-powerpc): the hsync and vsync pulses appear to be OK (correct frequency) but have a phase jitter.Unless somebody else posted it too, that would be me. And I now realise that it was based on your suggestion (on debian-powerpc) a year back!
Possible - I've suggested someone take a scope and debug this more than once :-)
Owen asked: How was it using OFFB? The phase is steady with the OFFB.quoted
Does that ring a bell with anyone here? Does anyone know which PLL setting the hsync position is derived from? MichaelIs it possible that the lcd and crt *have to be* on different controllers? From what I understand, OF and OSX set it up that way but we
Yep, that's entirely possible. Maybe we can't get the proper specs for both on one controller.
don't. As I have no documentation, this is just a conjecture. Still I would like to do just that. But I am constrained by the lack of documentation. Pointers anybody? Maybe people who desire a dual-head would like to help :)
I'd talk to Michel Dänzer about this. The XFree people might have figured something out on other (i386) architectures. XFree developers have access to at least some ATI docs. Michael ** Sent via the linuxppc-dev mail list. See http://lists.linuxppc.org/
