1625 6693 d 16 h decky /kernel/trunk/ ppc32 uspace keyboard support  
1613 6694 d 0 h palkovsky /kernel/trunk/generic/src/console/ Fixed klog to use correct vsnprintf.  
1612 6694 d 0 h jermar /kernel/trunk/generic/src/lib/ Generic version of memcpy that is resistent towards unaligned memory accesses.  
1605 6694 d 3 h cejka /kernel/trunk/generic/src/printf/ Another kernel printf return value fix.  
1604 6694 d 4 h cejka /kernel/trunk/ Fixed printf return value.  
1600 6694 d 6 h jermar /kernel/trunk/generic/src/proc/ Prevent task killing of kernel by returning EPERM on such a request.  
1599 6694 d 7 h palkovsky /kernel/trunk/generic/src/mm/ Blacklist first frame to avoid problems with allocator.  
1597 6694 d 7 h palkovsky /kernel/trunk/ Added possibility to interrupt task at exit from interrupt routine.  
1595 6694 d 8 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 6694 d 14 h jermar /kernel/trunk/generic/src/mm/ Never ever walk a B+tree as you destroy it. Or vice versa.  
1593 6694 d 15 h jermar /kernel/trunk/generic/src/synch/ When interrupted from sleep, pending timeouts must be unregistered.  
1591 6694 d 17 h palkovsky /kernel/trunk/generic/ Small updates to ipc.  
1589 6694 d 21 h jermar /kernel/trunk/generic/src/ Improve comments regarding liveliness of threads and tasks.  
1588 6694 d 21 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 6694 d 22 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 6695 d 1 h jermar /kernel/trunk/generic/src/synch/ futex_cleanup() implementation.  
1585 6695 d 1 h jermar /kernel/trunk/generic/ Kill task when its main thread exits.  
1583 6695 d 4 h jermar /kernel/trunk/generic/ Make ktaskclnp call ipc_cleanup and futex_cleanup.  
1582 6695 d 5 h palkovsky /kernel/trunk/generic/ Modified ipc_cleanup.  
1581 6695 d 7 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 6695 d 8 h jermar /kernel/trunk/generic/src/ Update for task_kill().  
1579 6695 d 17 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 6695 d 20 h jermar /kernel/trunk/ Make use of thread_join_timeout() and thread_detach() in kernel.

Improved comments in slab.h.		  
1573 6695 d 22 h palkovsky /kernel/trunk/generic/ Renamed some things in IPC to be consistent.
Added ipc reporting to kconsole.		  
1571 6695 d 22 h jermar /kernel/trunk/generic/ thread_join_timeout() and thread_detach() implementation.
Needs more thorough testing.		  
1568 6695 d 23 h palkovsky /kernel/trunk/generic/ Slightly remodelled ipc hangups to facilitate correct cleanup.
Doc updates for frame allocator.		  
1554 6696 d 17 h jermar /kernel/trunk/generic/src/mm/ Improve comment in slab.c.  
1550 6696 d 23 h jermar /kernel/trunk/generic/src/mm/ Remove left over piece of code for increasing reference count in ELF backend.  
1549 6697 d 0 h vana /kernel/trunk/generic/src/adt/ Bitmap functions patch  
1546 6697 d 1 h jermar /kernel/trunk/generic/src/mm/ Add reference to shared frames of ELF image backed address space area.  
1545 6697 d 1 h jermar /kernel/trunk/generic/src/mm/ Add reference to shared frames of anonymous address space area.  
1544 6697 d 1 h palkovsky /kernel/trunk/generic/ Slightly better behaviour with caching on memory sharing.  
1539 6697 d 8 h cejka /kernel/trunk/generic/src/mm/ Fixed warning about unused variable in non-debug mode.  
1507 6698 d 1 h vana /kernel/trunk/ IA64 uspace keyboard kernel part  
1502 6698 d 3 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 6698 d 14 h jermar /kernel/trunk/ Remove three infinite loops introduced yesterday :-)

Make ia64 ready to load 5 ELF images.		  
1494 6698 d 15 h palkovsky /kernel/trunk/generic/ Removes unnecessary parameter for map_physmem syscall.  
1483 6699 d 1 h jermar /kernel/trunk/generic/src/ Implement recursive function for deallocating the whole B+tree.
Make use of this function in address space management.		  
1474 6699 d 17 h palkovsky /kernel/trunk/ Added syscall that lets kernel regain access to keyboard.  
1468 6699 d 23 h jermar /kernel/trunk/ Function for destroying address space for which there is no other reference in the kernel.
