1595 6692 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 6692 d 16 h jermar /kernel/trunk/generic/src/mm/ Never ever walk a B+tree as you destroy it. Or vice versa.  
1593 6692 d 18 h jermar /kernel/trunk/generic/src/synch/ When interrupted from sleep, pending timeouts must be unregistered.  
1591 6692 d 19 h palkovsky /kernel/trunk/generic/ Small updates to ipc.  
1589 6692 d 23 h jermar /kernel/trunk/generic/src/ Improve comments regarding liveliness of threads and tasks.  
1588 6692 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 6693 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 6693 d 3 h jermar /kernel/trunk/generic/src/synch/ futex_cleanup() implementation.  
1585 6693 d 3 h jermar /kernel/trunk/generic/ Kill task when its main thread exits.  
1583 6693 d 6 h jermar /kernel/trunk/generic/ Make ktaskclnp call ipc_cleanup and futex_cleanup.  
1582 6693 d 7 h palkovsky /kernel/trunk/generic/ Modified ipc_cleanup.  
1581 6693 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 6693 d 10 h jermar /kernel/trunk/generic/src/ Update for task_kill().  
1579 6693 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.
 
1576 6693 d 22 h jermar /kernel/trunk/ Make use of thread_join_timeout() and thread_detach() in kernel.

Improved comments in slab.h.
 
1573 6694 d 0 h palkovsky /kernel/trunk/generic/ Renamed some things in IPC to be consistent.
Added ipc reporting to kconsole.
 
1571 6694 d 0 h jermar /kernel/trunk/generic/ thread_join_timeout() and thread_detach() implementation.
Needs more thorough testing.
 
1568 6694 d 1 h palkovsky /kernel/trunk/generic/ Slightly remodelled ipc hangups to facilitate correct cleanup.
Doc updates for frame allocator.
 
1554 6694 d 19 h jermar /kernel/trunk/generic/src/mm/ Improve comment in slab.c.  
1550 6695 d 1 h jermar /kernel/trunk/generic/src/mm/ Remove left over piece of code for increasing reference count in ELF backend.  
1549 6695 d 2 h vana /kernel/trunk/generic/src/adt/ Bitmap functions patch  
1546 6695 d 3 h jermar /kernel/trunk/generic/src/mm/ Add reference to shared frames of ELF image backed address space area.  
1545 6695 d 3 h jermar /kernel/trunk/generic/src/mm/ Add reference to shared frames of anonymous address space area.  
1544 6695 d 3 h palkovsky /kernel/trunk/generic/ Slightly better behaviour with caching on memory sharing.  
1539 6695 d 10 h cejka /kernel/trunk/generic/src/mm/ Fixed warning about unused variable in non-debug mode.  
1507 6696 d 3 h vana /kernel/trunk/ IA64 uspace keyboard kernel part  
1502 6696 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 6696 d 17 h jermar /kernel/trunk/ Remove three infinite loops introduced yesterday :-)

Make ia64 ready to load 5 ELF images.
 
1494 6696 d 17 h palkovsky /kernel/trunk/generic/ Removes unnecessary parameter for map_physmem syscall.  
1484 6697 d 3 h palkovsky /kernel/trunk/generic/include/ Added EINVAL error code.

Make use of this function in address space management.
 
1474 6697 d 19 h palkovsky /kernel/trunk/ Added syscall that lets kernel regain access to keyboard.  
1468 6698 d 1 h jermar /kernel/trunk/ Function for destroying address space for which there is no other reference in the kernel.  
1467 6698 d 1 h jermar /kernel/trunk/generic/src/synch/ Allow usage of blocking synchronization primitives in functions that are also called during system initialization.
