f985fded3e Added lock_and_signal::signal_all(), and made the rust_kernel::join() use wait instead of yield. 2010-09-10 14:38:31 -07:00

616b7afb72 Tidy up the sync dir, remove dead or mis-designed code in favour of OS primitives, switch rust_kernel to use a lock/signal pair and wait rather than spin. 2010-09-08 19:13:49 -07:00

de611a3090 Lots of design changes around proxies and message passing. Made it so that domains can only talk to other domains via handles, and with the help of the rust_kernel. 2010-09-07 18:44:12 -07:00

9b74129a4f Added a thread utility class to factor out operations on threads. 2010-09-07 18:41:07 -07:00

f8ff013e3c Added a few utility classes, cleaned up the include order of .h files, and started to make the Rust kernel own domain message queues rather than the Rust domains themselves. 2010-09-07 18:41:07 -07:00

64ff82ecf9 Implemented an lock free queue based on this paper http://www.cs.rochester.edu/~scott/papers/1996_PODC_queues.pdf, the "lock free queue" we had before wasn't lock free at all. 2010-08-24 21:07:14 -07:00

5d98a311e4 Putting out the burning tree on Windows. Turns out you can completely starve threads by not yielding on windows/vmware, really weird. 2010-08-16 18:44:26 -07:00

00d1465d13 Added a message passing system based on lock free queues for inter-thread communication. Channels now buffer on the sending side, and no longer require blocking when sending. Lots of other refactoring and bug fixes. 2010-07-19 14:05:18 -07:00
