1591 6626 d 19 h palkovsky /kernel/trunk/generic/ Small updates to ipc.  
1589 6626 d 23 h jermar /kernel/trunk/generic/src/ Improve comments regarding liveliness of threads and tasks.  
1588 6626 d 23 h jermar /kernel/trunk/generic/src/ In task_kill(), remove the task from the tasks_btree before proceeding.
Thus, when the kernel finds the task in the tasks_btree and locks it before
releasing tasks_lock, it is guaranteed that the task will not be destroyed
until the lock is held. If the kernel needs to unlock the task, do some operation
and lock it again, it should increase its refcount before doing so. In that case,
when releasing the lock, it must decrement the refcount and if it reaches
zero, it must call task_destroy().		  
1587 6627 d 0 h jermar /kernel/trunk/ task_destroy() implementation, fixes in as_destroy() and task_kill().
This is the first version of HelenOS that would perform complete cleanup leading from thread to destruction of address space.		  
1586 6627 d 3 h jermar /kernel/trunk/generic/src/synch/ futex_cleanup() implementation.  
1585 6627 d 3 h jermar /kernel/trunk/generic/ Kill task when its main thread exits.  
1583 6627 d 6 h jermar /kernel/trunk/generic/ Make ktaskclnp call ipc_cleanup and futex_cleanup.  
1582 6627 d 7 h palkovsky /kernel/trunk/generic/ Modified ipc_cleanup.  
1581 6627 d 9 h jermar /kernel/trunk/generic/src/ Detach kmp thread after joining it.
Extend assertion in thread_destroy() to not panic when threads are destroyed in their Unded state.		  
1580 6627 d 10 h jermar /kernel/trunk/generic/src/ Update for task_kill().  
1579 6627 d 19 h jermar /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.		  
1576 6627 d 22 h jermar /kernel/trunk/ Make use of thread_join_timeout() and thread_detach() in kernel.

Improved comments in slab.h.		  
1573 6628 d 0 h palkovsky /kernel/trunk/generic/ Renamed some things in IPC to be consistent.
Added ipc reporting to kconsole.		  
1571 6628 d 0 h jermar /kernel/trunk/generic/ thread_join_timeout() and thread_detach() implementation.
Needs more thorough testing.		  
1568 6628 d 1 h palkovsky /kernel/trunk/generic/ Slightly remodelled ipc hangups to facilitate correct cleanup.
Doc updates for frame allocator.		  
1554 6628 d 19 h jermar /kernel/trunk/generic/src/mm/ Improve comment in slab.c.  
1550 6629 d 1 h jermar /kernel/trunk/generic/src/mm/ Remove left over piece of code for increasing reference count in ELF backend.  
1549 6629 d 2 h vana /kernel/trunk/generic/src/adt/ Bitmap functions patch  
1546 6629 d 3 h jermar /kernel/trunk/generic/src/mm/ Add reference to shared frames of ELF image backed address space area.  
1545 6629 d 3 h jermar /kernel/trunk/generic/src/mm/ Add reference to shared frames of anonymous address space area.  
1544 6629 d 3 h palkovsky /kernel/trunk/generic/ Slightly better behaviour with caching on memory sharing.  
1539 6629 d 9 h cejka /kernel/trunk/generic/src/mm/ Fixed warning about unused variable in non-debug mode.  
1507 6630 d 3 h vana /kernel/trunk/ IA64 uspace keyboard kernel part  
1502 6630 d 5 h jermar /kernel/trunk/ 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.
O		  
1495 6630 d 16 h jermar /kernel/trunk/ Remove three infinite loops introduced yesterday :-)

Make ia64 ready to load 5 ELF images.		  
1494 6630 d 17 h palkovsky /kernel/trunk/generic/ Removes unnecessary parameter for map_physmem syscall.  
1484 6631 d 3 h palkovsky /kernel/trunk/generic/include/ Added EINVAL error code.

Make use of this function in address space management.		  
1474 6631 d 19 h palkovsky /kernel/trunk/ Added syscall that lets kernel regain access to keyboard.  
1468 6632 d 1 h jermar /kernel/trunk/ Function for destroying address space for which there is no other reference in the kernel.  
1467 6632 d 1 h jermar /kernel/trunk/generic/src/synch/ Allow usage of blocking synchronization primitives in functions that are also called during system initialization.

1460 6632 d 5 h jermar /kernel/trunk/generic/ Reference counting for futexes.  
1458 6632 d 19 h palkovsky /kernel/trunk/ Added console support to gxemul.
