Some question about Xrender and EXA | |
| [Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] | |
Hello, all. I have cross-compiled for the platform arm920-linux x-server. On the platform ARM920 (not equipped FPU), certain operations (I think related to the antialiased-operation: Porter-Duff operator, and so on), working slowly. For example, a utility cairo-perf, running on a dedicated powerful computer connected to the target platform through the network, shows a very slow operation. I will consider using own hardware implementation of 2D acceleration and writing xf86-video-* module according to the documentation on EXA-subsystem. Is that Xrender can use subsystem EXA to accelerate the work? What functions() can I profile in the process of software emulation EXA (for example, I want to make a module, which implements EXA in software) to find out the bottlenecks in performance? Thank you. -- Regards, Alexei Babich, circuit engineer, OOO NPP "Rezonans", Chelyabinsk, Russia http://www.rez.ru Jabber ID: impatt@xxxxxxxxx _______________________________________________ xorg mailing list xorg@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/xorg
