  • I pushed some updated patches to my drm-next-3.11 branch that should fix the outstanding issue with NI asics and also adds a debugfs interface for tracking the current power state.

    • Can dpm be enabled after loading radeon via sysfs, like dynpm?
      If not, would it be possible to change that?

        I just tried the new code on my 6870 and it does indeed seem to be working much better now. Thank you for fixing that, it was a deal breaker for me as the whole desktop would become unusable after a while.

        As of now I don't think that's possible, but I'd guess they will add support for that once it's more stable and thoroughly tested.

          I don't have any intention of supporting that. There are too many corner cases for weird interactions and for things to go wrong. Once DPM stabilizes, I'd like to deprecate the old code.

          • Latest Saucy builds for Ubuntu (drm-next) indeed seems to fix UVD on the Sony Vaio (RV710 ATI), though the screen flickering is still there. Unfortunately I can't find anything untoward in the usual logs or dmesg.

              well my 7770 certainly improved and i think i found the issue of the black screen, it does work when i disconnect my HDMI tv connection and leave only my DVI monitor but with both KMS have a nasty hang at start.

              another issue is if i start with the drm-next-3.11 kernel radeonsi doesnt seem to work correctly[it spawn 1 ksoftirq per core and give hell to the CPU], i assume llvm need update, so ill compile today revision[i have 30 jun] with libdrm today git and see if persist. drm-next-wip-5 works fine tho

              • My HD 6870 doesn't work with the latest patches. Once KMS is enabled during boot, the screen is covered in an abundant amount of artifacts that spell doom. It works with the previous patch set (drm-next-3.11-wip-5).

                I'm using Arch with the latest mesa/ati related packages found here.

                I noticed that HomeSp's 6870 is working fine with the latest patches, so oddly enough I'm hoping that this is a true regression and not PEBKAC, as I'd not like to waste anyone's time. Is there any information that I can give that might help resolve this?
