1605 6548 d 6 h cejka /kernel/trunk/generic/src/printf/ Another kernel printf return value fix.  
1604 6548 d 6 h cejka /kernel/trunk/ Fixed printf return value.  
1601 6548 d 9 h jermar /kernel/trunk/ Support loading up to 8 userspace images on ia64.  
1600 6548 d 9 h jermar /kernel/trunk/generic/src/proc/ Prevent task killing of kernel by returning EPERM on such a request.  
1599 6548 d 9 h palkovsky /kernel/trunk/generic/src/mm/ Blacklist first frame to avoid problems with allocator.  
1597 6548 d 9 h palkovsky /kernel/trunk/ Added possibility to interrupt task at exit from interrupt routine.  
1595 6548 d 10 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 6548 d 17 h jermar /kernel/trunk/generic/src/mm/ Never ever walk a B+tree as you destroy it. Or vice versa.  
1593 6548 d 18 h jermar /kernel/trunk/generic/src/synch/ When interrupted from sleep, pending timeouts must be unregistered.  
1591 6548 d 19 h palkovsky /kernel/trunk/generic/ Small updates to ipc.  
1589 6548 d 23 h jermar /kernel/trunk/generic/src/ Improve comments regarding liveliness of threads and tasks.  
1588 6548 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 6549 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 6549 d 3 h jermar /kernel/trunk/generic/src/synch/ futex_cleanup() implementation.  
1585 6549 d 4 h jermar /kernel/trunk/generic/ Kill task when its main thread exits.  
1583 6549 d 7 h jermar /kernel/trunk/generic/ Make ktaskclnp call ipc_cleanup and futex_cleanup.  
1582 6549 d 7 h palkovsky /kernel/trunk/generic/ Modified ipc_cleanup.  
1581 6549 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 6549 d 10 h jermar /kernel/trunk/generic/src/ Update for task_kill().  
1579 6549 d 20 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.
