There is no measurable penalty on single -threaded applications. - -NOTE that the only _driver_ which is thread safe at this time -is the OS/Mesa driver! - - -At present the mthreads code supports three thread APIS: - 1) POSIX threads (aka pthreads). - 2) Solaris / Unix International threads. - 3) Win32 threads (Win 95/NT). - -Support for other thread libraries can be added src/glthread.[ch] - - -In order to guarantee proper operation, it is -necessary for both Mesa and application code to use the same threads API. -So, if your application uses Sun's thread API, then you should build Mesa -using one of the targets for Sun threads. - -The mtdemos directory contains some example programs which use -multiple threads to render to osmesa rendering context(s). - -Linux users should be aware that there exist many different POSIX -threads packages. The best solution is the linuxthreads package -(http://pauillac.inria.fr/~xleroy/linuxthreads/) as this package is the -only one that really supports multiprocessor machines (AFAIK). See -http://pauillac.inria.fr/~xleroy/linuxthreads/README for further -information about the usage of linuxthreads. - -If you are interested in helping with thread safety work in Mesa -join the Mesa developers mailing list and post your proposal. - - -Regards, - John Stone -- j.stone@acm.org johns@cs.umr.edu - Christoph Poliwoda -- poliwoda@volumegraphics.com - - -Version info: - Mesa 2.6 - initial thread support. - Mesa 3.3 - thread support mostly rewritten (Brian Paul) |
