1.I recompile the pixman with enable-neon,but when I use the x11perf for testing ,I can‘t see the significant difference between the pixman with neon and pixman without neon.That's why?
Presumably because you're not hitting a neon-accelerated path. You've not said which x11perf tests you are measuring with. Be aware that many of them are not at all relevant for real world performance.
2.xserver use which drawing library to resizing the window,scroll the text window ,and so on? 3.which library excepts pixman could I optimize using neon to improve the performance of xserver?
The X server has an internal library called 'fb' for this. fb is a layer around pixman that implements X core rendering, either by calling down to pixman or directly.
