After the debugging for that, we found that(#8) The region is NULL. I have track it for several times, in the first, it will be not null, after several time try, It will be null(Actuall in function DoMakeCurrent, it has been null). Also I have added the checking, if null, return error. Still crash. Also I add the line to create the region(allocate the buffer by function intel_recreate_static_region) It will generate hardware issue (mass color). Haihao, do you have some idea about that? We check it in latest upstream code, it will use dri2 to create region(should use dri2 manage region). Seems work. However in Q3 release, don't support dri2, is there some new idea to make this resolved.

Since this is a general issue on all platforms, I increase the priority. If you need more information, please let me know. Thanks Created attachment 22699 [details] [review] detach static region from intel_renderbuffer on contex destroy This is a memory leaks issue, please cherry pick commit 7d99ddcb2bb09f1f54d91e6e20e42d217a5bccdf then apply the attached patch. Not works with RC3 release (Mesa Q3'08 release). Seems rapidly crash with several times try. About 1 or 2. Originally it will try with 5 times or more. Stefan, Do you have a try with the commit?

After patching the attachment, and restore my original testing environment, the bug seems fixed. Stefan, would you like to have a try? if works, please push them into SLED11. Thanks for Haihao's support. Thanks. I've applied the patches now to our Mesa package and submitted it for SLE11. Closing as fixed. Now for real. |
