| H A D | Jamfile | e8885f2097350aad05676d1d4af009375fe06a9b Thu Oct 22 13:24:12 UTC 2009 Axel Dörfler <axeld@pinc-software.de> Basically rewrote the ports subsystem to use:
* its own heap allocator instead of cbuf - this makes cbuf superfluous, and I
therefore removed it from the kernel. The heap is swappable, so lifts the
kernel's resource usage a bit. In the future, the heap should grow as well;
right now it should be at least as good as before.
* it no longer uses spinlocks, but just mutexes now for better scalability - it
was not usable with interrupts turned off anyway (due to its semaphore usage).
* it no longer uses semaphores, but condition variables.
* Needed to move the port initialization to a later point, as swappable memory
wasn't usable that early.
* All ports test are still passing, hopefully I didn't mess anything up :-)
