Avoid tricky race condition between waitq_wakeup() and the pair
of waitq_timeouted_sleep() and waitq_interrupt_sleep().
Mutual exclusion != Synchronization. |

Print spurious interrupt messages only when compiled with CONFIG_DEBUG.
Print warning about looping spinlock only after 100000000 unsuccessfull attempts to gain the spinlock. |

Update for task_kill(). |

6724 d 1 h |

/kernel/trunk/generic/ |
Framework for task_kill().
Some pieces (e.g. implementation of ktask_cleanup() kernel thread and
task_destroy() function) are missing.
Changed locking order for task lock, threads_lock and thread lock from
threads_lock, thread lock, task lock to task lock, threads_lock, thread lock. |

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.

Reference counting for futexes. |

Make implementation of condition variables compliant with their definition.
Signal operation must become a no-op if there is no thread in the wait operation.
Remove condvar_trywait() which has no meaning after this change. |

Small fixes in futex.c.
PTE_GET_FRAME() returns frame address, not PFN.

Increase "timeout" for debugging spinlock so that false positive
deadlock reports are suppressed on real hardware.
Also add one HT configuration to hardware compatibility list. |

Do not report possible deadlock on fb_lock.
This issue was causing troubles in connection
with slow framebuffer in simulated environment
when false positives triggered an infinite
recursion of attempts to report deadlock on
fb_lock using printf() and fb_putchar(). |

Complete implementation of copy_from_uspace() and copy_to_uspace()
for amd64 and ia32. Other architectures still compile and run,
but need to implement their own assembly-only memcpy(), memcpy_from_uspace(),
memcpy_to_uspace() and their failover parts. For these architectures
only dummy implementations are provided. |

Because of another race condition, futex_wakeup() needs to be able to allocate and initialize the kernel futex structure too. |

Cleanup of spinlocks, now compiles both ia32 and amd64 with
and without DEBUG_SPINLOCKS. Made spinlocks inline.
Moved syscall_handler to generic (it was identical for ia32,amd64 & mips32).
Made slightly faster syscall for ia32.
Made better interrupt routines for ia32.
Allow not saving non-scratch registers during interrupt on ia32,amd64,mips32.
Aligned interrupt handlers on ia32,amd64, this should prevent problems
with different instruction lengths. |

We are now almost -Wall clean.
- redefined atomic_t
- deleted many, many unused variables
- some minor code cleanups found using compiler warning. |

Add SPINLOCK_DECLARE and SPINLOCK_INITIALIZE macros.
SPINLOCK_DECLARE is to be used instead of direct spinlock_t declarations
in dynamically allocated structures on which spinlock_initialize() is called after
their creation.
SPINLOCK_INITIALIZE is to be used instead of direct spinlock_t declarations
of global spinlocks. It declares and initializes the spinlock.
Moreover, both macros are empty on UP so that -Wall warnings about unused structures
get supressed. |
