--- Comment #9 from Torsten Kaiser <[email protected]> 2012-01-31 10:55:48 PST --- That patch (attachment 56365) seems to work. The patched xf86-video-ati (6.14.3 + your first debugging patch) did not cause any GPU lockups with kernel 3.3-rc1 + Jerome's mutex fix for the GPU reset path + your DESKTOP_HEIGHT patch. While I do have a sure way to see if the bug has been triggered (GPU lockup messages in the syslog), I do not have a reliable way to seen if the trigger was there but without a lockup. I'm rather sure that it is fixed, but lacking a reliable way to trigger it, it is impossible to confirm this 100%. I will keep trying to trigger this and will definitely let you know, if that lockup returns. But I think I'm starting to lose the overview about how many interconnected bugs are in the play. Bug 1) Kernel causes a GPU lockup on invalid requests -> I think that one should be fixed by attachment 56365. Bug 2) Regression(?) in 6.14.2 to 6.14.3 that cause the driver to send these invalid request. Is attachment 56367 supposed to fix this? Do you want me to try that patch against vanilla 3.2 to see if there are still GPU lockups logged? Bug 3) Regression in 3.2 to 3.3-rc1 with the recursive mutex lock on GPU reset -> That one has been fixed in mainline with Jerome's patch Bug 4) Regression in 3.2 to 3.3-rc1 that the X server fails to recover from an GPU lockup even with Bug 3 fixed -> Do you think that its worth trying to find/fix this, even if with Bug 1 fixed these lockups can't be triggered anymore? -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ xorg-driver-ati mailing list [email protected] http://lists.x.org/mailman/listinfo/xorg-driver-ati
