1595 6583 d 5 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 6583 d 11 h jermar /kernel/trunk/generic/src/mm/ Never ever walk a B+tree as you destroy it. Or vice versa.  
1593 6583 d 12 h jermar /kernel/trunk/generic/src/synch/ When interrupted from sleep, pending timeouts must be unregistered.  
1591 6583 d 14 h palkovsky /kernel/trunk/generic/ Small updates to ipc.  
1589 6583 d 17 h jermar /kernel/trunk/generic/src/ Improve comments regarding liveliness of threads and tasks.  
1588 6583 d 18 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 6583 d 19 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 6583 d 22 h jermar /kernel/trunk/generic/src/synch/ futex_cleanup() implementation.  
1585 6583 d 22 h jermar /kernel/trunk/generic/ Kill task when its main thread exits.  
1583 6584 d 1 h jermar /kernel/trunk/generic/ Make ktaskclnp call ipc_cleanup and futex_cleanup.  
1582 6584 d 2 h palkovsky /kernel/trunk/generic/ Modified ipc_cleanup.  
1581 6584 d 4 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 6584 d 4 h jermar /kernel/trunk/generic/src/ Update for task_kill().  
1579 6584 d 14 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 6584 d 16 h jermar /kernel/trunk/ Make use of thread_join_timeout() and thread_detach() in kernel.

Improved comments in slab.h.
 
1573 6584 d 19 h palkovsky /kernel/trunk/generic/ Renamed some things in IPC to be consistent.
Added ipc reporting to kconsole.
 
1571 6584 d 19 h jermar /kernel/trunk/generic/ thread_join_timeout() and thread_detach() implementation.
Needs more thorough testing.
 
1568 6584 d 20 h palkovsky /kernel/trunk/generic/ Slightly remodelled ipc hangups to facilitate correct cleanup.
Doc updates for frame allocator.
 
1554 6585 d 14 h jermar /kernel/trunk/generic/src/mm/ Improve comment in slab.c.  
1550 6585 d 20 h jermar /kernel/trunk/generic/src/mm/ Remove left over piece of code for increasing reference count in ELF backend.  
1549 6585 d 21 h vana /kernel/trunk/generic/src/adt/ Bitmap functions patch  
1546 6585 d 22 h jermar /kernel/trunk/generic/src/mm/ Add reference to shared frames of ELF image backed address space area.  
1545 6585 d 22 h jermar /kernel/trunk/generic/src/mm/ Add reference to shared frames of anonymous address space area.  
1544 6585 d 22 h palkovsky /kernel/trunk/generic/ Slightly better behaviour with caching on memory sharing.  
1539 6586 d 4 h cejka /kernel/trunk/generic/src/mm/ Fixed warning about unused variable in non-debug mode.  
1507 6586 d 22 h vana /kernel/trunk/ IA64 uspace keyboard kernel part  
1502 6587 d 0 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 6587 d 11 h jermar /kernel/trunk/ Remove three infinite loops introduced yesterday :-)

Make ia64 ready to load 5 ELF images.
 
1494 6587 d 12 h palkovsky /kernel/trunk/generic/ Removes unnecessary parameter for map_physmem syscall.

Make use of this function in address space management.
 
1474 6588 d 14 h palkovsky /kernel/trunk/ Added syscall that lets kernel regain access to keyboard.  
1468 6588 d 20 h jermar /kernel/trunk/ Function for destroying address space for which there is no other reference in the kernel.  
1467 6588 d 20 h jermar /kernel/trunk/generic/src/synch/ Allow usage of blocking synchronization primitives in functions that are also called during system initialization.
