Hi, I've written a proof-of-concept module of what could be a Linux way of supporting thread pool regulation, and in particular pthread_worqueue kind of API. [0] I've published the code on [1] and you can have a look at how the kernel support "works" on [2] (asciidoc generated, may be a bit late from the one in the repository). On [3] there is a small "library", more like hints of how to use the API. I sadly don't have enough time to make a tentative port of mark's libpthread-workqueue using this kernel module, hence wonder if there are people who would be interested into that kind of work. Enjoy… PS: the kernel module has been tested very lightly with stuff like [4], I've, *I think*, found all the possible issues and are reasonably confident with the correctness of the code. Though I'd strongly advise you to use it in a virtual machine at first. It mucks about with the scheduler, very bad things can happen which often results in deadlocked kernel at best, kernel panics at worst… [0] https://plus.google.com/102418560027665797123/posts/jQMUfb53c5n [1] http://git.madism.org/?p=~madcoder/pwqr.git;a=summary [2] http://madism.org/~madcoder/pwqr.html [3] http://git.madism.org/?p=~madcoder/pwqr.git;a=blob;f=lib/libpwqr.c;hb=HEAD [4] http://git.madism.org/?p=~madcoder/pwqr.git;a=blob;f=test/test.c;hb=HEAD -- Intersec <http://www.intersec.com> Pierre Habouzit <pierre.habouzit@intersec.com> | Chief Scientist Mob : +33 (0)6 1636 8131 37 Rue Pierre Lhomme 92400 Courbevoie
