its allocation failed. |

/trunk/kernel/generic/ |
Implement a new mechanism for copying data between two address spaces based on
IPC. New system method IPC_M_DATA_SEND is introduced. The implementation is
generic and does not make use of any possible architecture optimizations such as
direct copy from one address space to another. |

Some left-over stuff from the last commit (IPC cleanup and improved
comments.) |

Greatly improve comments in the IPC layer.
Now I think I finally start to understand our IPC internals :-) |

Cleanup the waitq_wakeup() interface.
Replace numeric constants (i.e. 0)
and boolean constants (i.e. false) with
more readable WAKEUP_FIRST. Also change the
type of the second argument of waitq_wakeup()
to a newly introduced type wakeup_mode_t.
Fix behaviour of waitq_wakeup() in case
that WAKEUP_ALL semantics is required
but no threads are sleeping in the wait
queue. This is a similar fix to that of
Jan Hudecek committed in the RCU branch,
but, IMHO, is more straightforward and
also doesn't eat up previous missed
wakeups. |

Continue to de-oversynchronize the kernel.
- replace as->refcount with an atomic counter; accesses to this
reference counter are not to be done when the as->lock mutex is held;
this gets us rid of mutex_lock_active();
Remove the possibility of a deadlock between TLB shootdown and asidlock.
- get rid of mutex_lock_active() on as->lock
- when locking the asidlock spinlock, always do it conditionally and with
preemption disabled; in the unsuccessful case, enable interrupts and try again
- there should be no deadlock between TLB shootdown and the as->lock mutexes
- PLEASE REVIEW !!!
Add DEADLOCK_PROBE's to places where we have spinlock_trylock() loops. |

Replace nonblocking argument of waitq_sleep_timeout with flags that specify mode of operation.
Now a flag can be used to specify interruptible sleep.
Modify waitq_interrupt_sleep() to only interrupt threads that used this flag.

Added support for IRQ notifiactions.
- seems to work correctly on ia32, amd64
- the mips kbd probably lowers interrupts when the char is read from
the port, we will have to find a way how to deal with it. |

Completed ipc_cleanup, it should be somehow integrated into
cleanup of task. The function can sleep. |
