https://bugs.freedesktop.org/show_bug.cgi?id=48880 --- Comment #21 from Alex Deucher <agd5f@xxxxxxxxx> 2012-04-19 07:20:44 PDT --- (In reply to comment #20) > What about the BIOS bug angle? Because kernel is not setting up the hardware > directly, but asking the BIOS to do it, right? Is that out of the question? It's not out of the question, but I highly doubt it. The driver calculates the pll dividers and the atom table basically writes them to the pll registers. If there was a bug in the table, I'd expect it to cause problems across the board, not just on one mode on one monitor. We've had lots of these kind of bugs over the course of the driver's life. Some combinations of dividers and monitors are just not happy. The trick is to tweak the algo just enough to fix the problematic monitor while not breaking others. I'll test RADEON_PLL_USE_FRAC_FB_DIV on the hw I have here and if all goes well, I'll send it to Dave. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
