2012-09-19core: Allocate threads on demand, not on scheduler startupPhilipp Brüschweiler-7/+6
API change: rust_kernel::create_scheduler() or rust_scheduler::rust_scheduler() respecitevly now take ownership of the launch factory argument, it is needed to create new threads on demand. Also renames rustrt::sched_threads() to rustrt::rust_sched_threads() for consistency. Added rustrt::rust_max_sched_threads() to return the maximal number of scheduled threads of the current scheduler. Fixes #3493.

2012-04-03Refactor includes structure, getting rid of rust_internal.hJon Morton-1/+3
Many changes to code structure are included: - removed TIME_SLICE_IN_MS - removed sychronized_indexed_list - removed region_owned - kernel_owned move to kernel.h, task_owned moved to task.h - global configs moved to rust_globals.h - changed #pragma once to standard guard in rust_upcall.h - got rid of memory.h

2012-03-31rt: Extract rust_sched_launcher from rust_task_threadBrian Anderson-3/+5
rust_sched_launcher is actually responsible for setting up the thread and starting the loop. There will be other implementations that do not actually set up a new thread, in order to support scheduling tasks on the main OS thread.
2012-03-31Choose task thread in rust_scheduler by round robinJon Morton-2/+2
Remove the random context from rust_scheduler and use a simple round robin system to choose which thread a new task gets put on. Also, some incorrect tab indents around scoped blocks were fixed.

2012-02-27rt: Change the way the kernel exits to avoid pthread leaksBrian Anderson-0/+1
This makes the kernel join every scheduler thread before exiting in order to ensure that all threads are completely terminated before the process exits. On my machine, for 32-bit targets, this was causing regular valgrind errors.
2012-02-08rt: Export a scheduler APIBrian Anderson-0/+2
2012-02-08rt: Change the lifecycle of tasks and schedulers for various reasonsBrian Anderson-1/+6
This is in preparation for giving schedulers their own life cycle separate from the kernel. Tasks must be deleted before their scheduler thread, so we can't let the scheduler exit before all its tasks have been cleaned up. In this scheme, the scheduler will unregister tasks with the kernel when they are reaped, then drop their ref on the task (there may still be others). When the task ref count hits zero, the task will request to be unregistered from the scheduler, which is responsible for deleting the task. Instead of having the kernel tell the scheduler to exit, let the scheduler decide when to exit. For now it will exit when all of its tasks are unregistered.
2012-02-08rt: Introduce scheduler idsBrian Anderson-1/+4
2012-02-08rt: Change the scheme used for terminating the kernelBrian Anderson-1/+9
Instead of joining on the scheduler threads, instead keep a count of active schedulers. When there are no more schedulers raise a signal for the main thread to continue. This will be required once schedulers can be added and removed from the running kernel.

2012-02-02rt: Only wake up all schedulers when no tasks are leftBrian Anderson-0/+5
At the moment there's not really any reason to be raising this signal, since they schedulers wake up periodically anyway, but once we remove the timer this will be how the schedulers know to exit.
2012-01-29rt: Make the initial segment of the main task's stack 1MBBrian Anderson-1/+2
This is a trick to fool microbenchmarks. Closes #1681

2011-08-10rt: Shutdown gracefully on failureBrian Anderson-0/+2
When the kernel fails, kill all tasks and wait for the schedulers to stop instead of just exiting. I'm sure there are tons of lurking issues here but this is enough to fail without leaking (at least in the absence of cleanups).
2011-08-08Introduced task handles.unknown-3/+0
This is the new way to refer to tasks in rust-land. Currently all they do is serve as a key to look up the old rust_task structure. Ideally they won't be ref counted, but baby steps.
2011-07-29Removing proxies and message queues.Eric Holk-10/+3
2011-07-28Do all runtime calls to getenv at initializationBrian Anderson-0/+3
getenv is not threadsafe and (maybe as a result) it's randomly crashing with CFLAGS=-g and RUST_THREADS=32. Calls from rust code are still on their own.
2011-07-28Updating to work on Windows.Eric Holk-0/+6
2011-07-28Per-thread scheduling. Closes #682.Eric Holk-5/+11
Tasks are spawned on a random thread. Currently they stay there, but we should add task migration and load balancing in the future. This should drammatically improve our task performance benchmarks.
