1605 6601 d 9 h cejka /kernel/trunk/generic/src/printf/ Another kernel printf return value fix.  
1604 6601 d 9 h cejka /kernel/trunk/ Fixed printf return value.  
1600 6601 d 12 h jermar /kernel/trunk/generic/src/proc/ Prevent task killing of kernel by returning EPERM on such a request.  
1599 6601 d 12 h palkovsky /kernel/trunk/generic/src/mm/ Blacklist first frame to avoid problems with allocator.  
1597 6601 d 13 h palkovsky /kernel/trunk/ Added possibility to interrupt task at exit from interrupt routine.  
1595 6601 d 13 h palkovsky /kernel/trunk/ Added kernel circular buffer klog.
Added automatic killing of tasks raising inappropriate exceptions.
TODO: Fix vsnprintf return value(and behaviour according to specs) and remove workaround in klog.		  
1594 6601 d 20 h jermar /kernel/trunk/generic/src/mm/ Never ever walk a B+tree as you destroy it. Or vice versa.  
1593 6601 d 21 h jermar /kernel/trunk/generic/src/synch/ When interrupted from sleep, pending timeouts must be unregistered.  
1591 6601 d 23 h palkovsky /kernel/trunk/generic/ Small updates to ipc.  
1589 6602 d 2 h jermar /kernel/trunk/generic/src/ Improve comments regarding liveliness of threads and tasks.  
1588 6602 d 3 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 6602 d 4 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 6602 d 7 h jermar /kernel/trunk/generic/src/synch/ futex_cleanup() implementation.  
1585 6602 d 7 h jermar /kernel/trunk/generic/ Kill task when its main thread exits.  
1583 6602 d 10 h jermar /kernel/trunk/generic/ Make ktaskclnp call ipc_cleanup and futex_cleanup.  
1582 6602 d 11 h palkovsky /kernel/trunk/generic/ Modified ipc_cleanup.  
1581 6602 d 13 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 6602 d 13 h jermar /kernel/trunk/generic/src/ Update for task_kill().  
1579 6602 d 23 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 6603 d 1 h jermar /kernel/trunk/ Make use of thread_join_timeout() and thread_detach() in kernel.

Improved comments in slab.h.		  
1573 6603 d 4 h palkovsky /kernel/trunk/generic/ Renamed some things in IPC to be consistent.
Added ipc reporting to kconsole.		  
1571 6603 d 4 h jermar /kernel/trunk/generic/ thread_join_timeout() and thread_detach() implementation.
Needs more thorough testing.		  
1568 6603 d 5 h palkovsky /kernel/trunk/generic/ Slightly remodelled ipc hangups to facilitate correct cleanup.
Doc updates for frame allocator.		  
1554 6603 d 23 h jermar /kernel/trunk/generic/src/mm/ Improve comment in slab.c.  
1550 6604 d 5 h jermar /kernel/trunk/generic/src/mm/ Remove left over piece of code for increasing reference count in ELF backend.  
1549 6604 d 6 h vana /kernel/trunk/generic/src/adt/ Bitmap functions patch  
1546 6604 d 7 h jermar /kernel/trunk/generic/src/mm/ Add reference to shared frames of ELF image backed address space area.  
1545 6604 d 7 h jermar /kernel/trunk/generic/src/mm/ Add reference to shared frames of anonymous address space area.  
1544 6604 d 7 h palkovsky /kernel/trunk/generic/ Slightly better behaviour with caching on memory sharing.  
1539 6604 d 13 h cejka /kernel/trunk/generic/src/mm/ Fixed warning about unused variable in non-debug mode.  
1507 6605 d 7 h vana /kernel/trunk/ IA64 uspace keyboard kernel part  
1502 6605 d 9 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 6605 d 20 h jermar /kernel/trunk/ Remove three infinite loops introduced yesterday :-)

Make ia64 ready to load 5 ELF images.		  
1494 6605 d 21 h palkovsky /kernel/trunk/generic/ Removes unnecessary parameter for map_physmem syscall.  
1483 6606 d 7 h jermar /kernel/trunk/generic/src/ Implement recursive function for deallocating the whole B+tree.

1468 6607 d 5 h jermar /kernel/trunk/ Function for destroying address space for which there is no other reference in the kernel.  
1467 6607 d 5 h jermar /kernel/trunk/generic/src/synch/ Allow usage of blocking synchronization primitives in functions that are also called during system initialization.  
1461 6607 d 7 h palkovsky /kernel/trunk/generic/ Slightly changed semantics of AS_AREA_SEND/RECV.  
1460 6607 d 9 h jermar /kernel/trunk/generic/ Reference counting for futexes.
