Do Radeons have a CP command to write an arbitrary value to some place in memory?
If so, you may want to use that to implement userspace-accessible fencing in the obvious way and then use the fenced bufmgr, which would do that with no pipebuffer changes and no kernel calls. Otherwise, maybe change the kernel module to write a fence number in an mmapable place on fence irqs? ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
