I'd like to get a quick additional review of these patches before applying. I'd ideally also like to see these applied and uploaded before our Beta-2 freeze this Thurs Sep 20 for more widespread testing. I would also note that I've received initial testing feedback on 2 development platforms with Haswell graphics. Results are as follows: For each, normally the monitor (Iiyama ProLite E2209HDS) can handle 1920x1080 and 1280x1024 VGA. Laptop Platform (Beta HW): * HDMI: 1920x1080, 1280x1024, 1024x768, 800x600 - all work fine * DisplayPort: 1920x1080, 1280x1024, 1024x768, 800x600 - all work fine * VGA: 1024x768, 800x600, works fine - 1280x1024, not stretched fill width on monitor - 1920x1080, edges fall off the monitor, can't sync up * A S3 test cycle running glxgears, the machine locked up on the 1st iteration and on reboot can't get any USB keyboards to currently work. suspect the USB keyboard problem is a completely different issue though. Desktop Platform (Alpha HW): * HDMI: 1920x1080, 1280x1024, 1024x768, 800x600 - all work fine * Display Port: No output at all (even on UEFI boot, this is probably an alpha board issue, not a kernel problem). * VGA: Same as Laptop Platform: - 1024x768, 800x600, works fine - 1280x1024, not stretched fill width on monitor - 1920x1080, edges fall off the monitor, can't sync up. The image is not very stable. Again, saw this issue on the early laptop board, so it's a silicon/board issue probably. * And S3 reboots the machine on 1st iteration, so the same as the laptop SDP - however, this time USB works fine (thankfully!). So while not completely perfect feedback from initial non-exhaustive testing, I do feel it is worthwhile applying these patches while in the process of fixing the remaining outlying issues. I've also tested on non-Haswell kit to confirm no regressions. For anyone else interested in testing, I've posted a test kernel at the following location: <meta http-equiv="content-type" content="text/html; charset=ISO-8859-1"> <a href="http://people.canonical.com/%7Eogasawara/lp1011440/">http://people.canonical.com/~ogasawara/lp1011440/</a> Please review the pull request below.
