Lots of Changes for Intel Graphics Coming in Linux 3.9

Posted by Unknown on from the crush-all-insects dept.

With the Linux 3.8 merge over, the Intel Linux graphics developers are looking toward 3.9. From a weblog entry by one of them: "Let's first look at bit at the drm core changes: The headline item this time around is the reworked kernel modeset locking. Finally the kernel doesn't stall for a few frames while probing outputs in the background! ... For general robustness of our GEM implementation we've clarified the various gpu reset state transitions. This should prevent applications from crashing while a gpu reset is going on due to the kernel leaking that transitory state to userspace. Ville Syrjälä also started to fix up our handling of pageflips across gpu hangs so that compositors no longer get stuck after a reset. Unfortunately not all of his patches made it into 3.9. Somewhat related is Mika Kuoppala's work to fix bugs across the seqnqo wrap-around. And to make sure that those bugs won't pop up again he also added some testing infrastructure. " The thing I am most looking forward to is the gen4 relocation regression finally being fixed. No more GPU hangs when under heavy I/O load (the bane of my existence for a while now). The bug report is a good read if you think hunting for a tricky bug is fun.

    First, they would have to demonstrate more graphics aptitude than they have to date... Not all of us will accept inferior performance to get an untainted kernel.

    You need to stop blaming Windows and/or the GPU vendor and troubleshoot your system. My GPU has reset precisely zero times when playing BF3, over a total of about 107 hours. I have seen GPU resets on my system on rare occasion, generally with broken software, but never in BF3 and I have more than a bit of testing with it.

    You have something wrong on your system, you should figure out what.

    And I only see AMD/ATI by choice because I know with an nVidia graphics chip there is no hope of an open source driver coming from then. Guess we both are voting with our wallets. Your vote is for "please me now", my vote is for "please me forever".
