1605 6615 d 2 h cejka /kernel/trunk/generic/src/printf/ Another kernel printf return value fix.  
1604 6615 d 2 h cejka /kernel/trunk/ Fixed printf return value.  
1601 6615 d 5 h jermar /kernel/trunk/ Support loading up to 8 userspace images on ia64.  
1600 6615 d 5 h jermar /kernel/trunk/generic/src/proc/ Prevent task killing of kernel by returning EPERM on such a request.  
1599 6615 d 5 h palkovsky /kernel/trunk/generic/src/mm/ Blacklist first frame to avoid problems with allocator.  
1597 6615 d 6 h palkovsky /kernel/trunk/ Added possibility to interrupt task at exit from interrupt routine.  
1595 6615 d 6 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 6615 d 13 h jermar /kernel/trunk/generic/src/mm/ Never ever walk a B+tree as you destroy it. Or vice versa.  
1593 6615 d 14 h jermar /kernel/trunk/generic/src/synch/ When interrupted from sleep, pending timeouts must be unregistered.  
1591 6615 d 16 h palkovsky /kernel/trunk/generic/ Small updates to ipc.  
1589 6615 d 19 h jermar /kernel/trunk/generic/src/ Improve comments regarding liveliness of threads and tasks.  
1588 6615 d 20 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 6615 d 21 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 6616 d 0 h jermar /kernel/trunk/generic/src/synch/ futex_cleanup() implementation.  
1585 6616 d 0 h jermar /kernel/trunk/generic/ Kill task when its main thread exits.  
1583 6616 d 3 h jermar /kernel/trunk/generic/ Make ktaskclnp call ipc_cleanup and futex_cleanup.  
1582 6616 d 3 h palkovsky /kernel/trunk/generic/ Modified ipc_cleanup.  
1581 6616 d 6 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 6616 d 6 h jermar /kernel/trunk/generic/src/ Update for task_kill().  
1579 6616 d 16 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.
