and compiz works well on g45. below is the first bad commit: commit fc6d89145df6fc7a1c2ce648b474c3f203ca87c7 Author: Robert Ellison <papillo@vmware.com> Date: Fri May 8 14:42:47 2009 -0600 i965: fix memory leak in context/renderbuffer region management A temporary change to the intelMakeCurrent() function to make it work with frame buffer objects causes the static regions associated with the context (the front_region, back_region, and depth_region) to take on an additional reference, with no corresponding release. This causes a memory leak if a program repeatedly creates and destroys contexts. The fix is the corresponding hack, to unreference these regions when the context is deleted, but only if the framebuffer objects are still present and the same regions are still referenced within. Both sets of code have comment blocks referring to each other. Haien, does this still exist? How about 7.5 branch? (In reply to comment #4) > Haien, does this still exist? How about 7.5 branch? > yes, still exists. but it works with 7.5 branch. Please retest with: commit 3020b1d43e34fca08cd51f7c7c8ed51497d49ef3 Author: Michel Dänzer <daenzer@vmware.com> Date: Tue Jun 23 16:45:40 2009 +0200 glx: Clean up more thoroughly if the drawable of a current context goes away. Fixes crash when restarting compiz, due to cl->currentContexts[x] being stale. the issue has gone. verified with below commits: Libdrm: (master)fbac5891b91c795de61f4d7cbc1a6799474364ad Mesa: (master)8ae02a3919bf31bd33f86208472e100eedb58497 Xserver: (master)3525d140567e0ad5f0184e4b37893c47239e1628 Xf86_video_intel: (master)4100abdf5d208bbcbb4ceabad0572c04221443c9 Kernel: (drm-intel-next)1ae8c0a56eeb3ed358b78ccadd024d6b721f26bc |
