1604 6590 d 11 h cejka /kernel/trunk/ Fixed printf return value.  
1601 6590 d 13 h jermar /kernel/trunk/ Support loading up to 8 userspace images on ia64.  
1600 6590 d 14 h jermar /kernel/trunk/generic/src/proc/ Prevent task killing of kernel by returning EPERM on such a request.  
1599 6590 d 14 h palkovsky /kernel/trunk/generic/src/mm/ Blacklist first frame to avoid problems with allocator.  
1597 6590 d 14 h palkovsky /kernel/trunk/ Added possibility to interrupt task at exit from interrupt routine.  
1595 6590 d 15 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 6590 d 22 h jermar /kernel/trunk/generic/src/mm/ Never ever walk a B+tree as you destroy it. Or vice versa.  
1593 6590 d 23 h jermar /kernel/trunk/generic/src/synch/ When interrupted from sleep, pending timeouts must be unregistered.  
1591 6591 d 0 h palkovsky /kernel/trunk/generic/ Small updates to ipc.  
1589 6591 d 4 h jermar /kernel/trunk/generic/src/ Improve comments regarding liveliness of threads and tasks.  
1588 6591 d 4 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 6591 d 5 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 6591 d 8 h jermar /kernel/trunk/generic/src/synch/ futex_cleanup() implementation.  
1585 6591 d 8 h jermar /kernel/trunk/generic/ Kill task when its main thread exits.  
1583 6591 d 12 h jermar /kernel/trunk/generic/ Make ktaskclnp call ipc_cleanup and futex_cleanup.  
1582 6591 d 12 h palkovsky /kernel/trunk/generic/ Modified ipc_cleanup.  
1581 6591 d 14 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 6591 d 15 h jermar /kernel/trunk/generic/src/ Update for task_kill().  
1579 6592 d 1 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 6592 d 3 h jermar /kernel/trunk/ Make use of thread_join_timeout() and thread_detach() in kernel.

Improved comments in slab.h.
 
1573 6592 d 5 h palkovsky /kernel/trunk/generic/ Renamed some things in IPC to be consistent.
Added ipc reporting to kconsole.
 
1571 6592 d 5 h jermar /kernel/trunk/generic/ thread_join_timeout() and thread_detach() implementation.
Needs more thorough testing.
 
1570 6592 d 6 h vana /kernel/trunk/arch/ia64/src/ski/ Ia64 keyboard extension  
1568 6592 d 7 h palkovsky /kernel/trunk/generic/ Slightly remodelled ipc hangups to facilitate correct cleanup.
Doc updates for frame allocator.
 
1554 6593 d 1 h jermar /kernel/trunk/generic/src/mm/ Improve comment in slab.c.  
1550 6593 d 6 h jermar /kernel/trunk/generic/src/mm/ Remove left over piece of code for increasing reference count in ELF backend.  
1549 6593 d 8 h vana /kernel/trunk/generic/src/adt/ Bitmap functions patch  
1548 6593 d 8 h vana /kernel/trunk/arch/ia64/src/ From/to kernel console switching on ia64  
1546 6593 d 8 h jermar /kernel/trunk/generic/src/mm/ Add reference to shared frames of ELF image backed address space area.  
1545 6593 d 8 h jermar /kernel/trunk/generic/src/mm/ Add reference to shared frames of anonymous address space area.  
1544 6593 d 8 h palkovsky /kernel/trunk/generic/ Slightly better behaviour with caching on memory sharing.  
1543 6593 d 12 h palkovsky /kernel/trunk/doc/ Note about mips bug making tetris to fail.  
1541 6593 d 14 h jermar /kernel/trunk/ Modify ia64 to load 6 userspace tasks.
Tetris however makes the kernel fault on unaligned memory access in copy_from_uspace.
 
1540 6593 d 14 h jermar /kernel/trunk/arch/ia32/src/smp/ Fix programming of local APIC timer to interrupt the processor
in the proper relation to HZ. (Was hardcoded to be each 1ms,
but should have been each 10ms).
 
1539 6593 d 15 h cejka /kernel/trunk/generic/src/mm/ Fixed warning about unused variable in non-debug mode.  
1537 6593 d 22 h palkovsky /kernel/trunk/ Added tetris to  
1527 6594 d 4 h jermar /kernel/trunk/contrib/conf/ Enable loading of kbd userspace driver in Ski sample configuration file.  
1511 6594 d 8 h palkovsky /kernel/trunk/arch/ Remove __address from include file included by uspace  
1507 6594 d 8 h vana /kernel/trunk/ IA64 uspace keyboard kernel part  
1502 6594 d 10 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.
