Just to be clear here, what is the same and what is different between the two systems? Ville can you please point at a branch with your fbc patches, presuming your tracking improvements should help here? (In reply to comment #1) > Just to be clear here, what is the same and what is different between the > two systems? Test on HSW-D/IVB-D with same things: - the same driver: Kernel, X11R7(Mesa,cairo,xf86) - enabling SNA - Raw X(xinit) Only different things is OS: Ubuntu 13.10 and Fedora 19 Can you please attach Xorg.0.log from both to see if that shows any defaults that different between the two platforms?

The IVB machine is broken. The fedora install has a broken libglx.so in the server that causes X to die in a fireball, and the ubuntu install is using the wrong kernel and has an old intel_drv.so which prevents X from starting. That needs to be resolved. The two HSW logs are from a Ubuntu system using the wrong kernel, and again have the invalid intel_drv.so preventing X from starting. (In reply to comment #9) sorry,last time to the wrong log,update it now. Created attachment 90130 [details]

There's one last oddity present on all machines: GLX is being routed through swrast. Now that intel appears to be loaded on all setups, can you please confirm the original bug. (In reply to comment #15) Retest with same driver on HSW,the results are same as last time: Ubuntu:0.638s Fedora:0.225s What's the variance? (In reply to comment #17) The results did not variance. I see no reason to explain the discrepancy so keep digging. Perhaps a perf profile of the two might indicate the issue if it is CPU bound. After updated system libs(by apt-get) on our mahcine (ubuntu 13.10), ocitysmap.trace improved to Fedora's result. We are trying to find out which system lib that cause the improvement. If we haven't found out the relevant package by now, likely we won't until next time we succumb. Closed it. |
