Would it be impolite to point out that you are running indirect on the local host and that this bug already has an immediate fix, but the root cause is a likely to be a memory/object leak by the client? commit 13bab58f04c1ec6d0d52760eab490a0997d9abe2 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Fri Feb 18 17:51:10 2011 +0000 i965: Fallback on encountering a NULL render buffer Following a GPU hang, or other error, the render target is not likely to have an allocated BO and so we must fallback to avoid using it. Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=32534 Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> *** This bug has been marked as a duplicate of bug 32534 *** Hello and thanks for the quick answer. May I lack of english language precision, but this is what I got from your answer: >you are running indirect on the local host mmm, if you refer to indirect rendering, I'm not sure about this. From the X log I get: [ 186.604] (II) intel(0): direct rendering: DRI2 Enabled >and that this bug already has an immediate fix I'm sorry about this is a dupe, I came accross the original one, but I was unable to position it on the mesa tree/branches so I wasn't sure the version I run included the fix or not. >the root cause is a likely to be a memory/object leak by the client ok, so KWin to blame, right? Anyway I understand this bug is a stupid load for the work you are doing and which I appreciate, so don't feel in the obligation to answer this. As I said I'm more than happy with your answer and with a fix. And no, you are not impolite, it's me not having been careful enough. Regards, |
