Any idea whether this will be applied or not? We find that it resolves a bug for Ubuntu. https://bugs.launchpad.net/ubuntu/+source/linux/+bug/554569?comments=all Thanks, Steve Conklin On Tue, Jul 6, 2010 at 3:21 AM, Zhenyu Wang wrote: > On 2010.07.02 16:43:30 -0400, Adam Jackson wrote: >> Fixe

Fixes an Ironlake laptop with a 68.940MHz 1280x800 panel and 120MHz SSC reference clock. More generally, the 0.488% tolerance used before is just too tight to reliably find a PLL setting. I extracted the search algorithm and modified it to find the dot clocks with maximum error over the valid ran
