1604 6554 d 5 h cejka /kernel/trunk/ Fixed printf return value.  
1601 6554 d 7 h jermar /kernel/trunk/ Support loading up to 8 userspace images on ia64.  
1600 6554 d 8 h jermar /kernel/trunk/generic/src/proc/ Prevent task killing of kernel by returning EPERM on such a request.  
1599 6554 d 8 h palkovsky /kernel/trunk/generic/src/mm/ Blacklist first frame to avoid problems with allocator.  
1597 6554 d 8 h palkovsky /kernel/trunk/ Added possibility to interrupt task at exit from interrupt routine.  
1595 6554 d 9 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 6554 d 16 h jermar /kernel/trunk/generic/src/mm/ Never ever walk a B+tree as you destroy it. Or vice versa.  
1593 6554 d 17 h jermar /kernel/trunk/generic/src/synch/ When interrupted from sleep, pending timeouts must be unregistered.  
1591 6554 d 18 h palkovsky /kernel/trunk/generic/ Small updates to ipc.  
1589 6554 d 22 h jermar /kernel/trunk/generic/src/ Improve comments regarding liveliness of threads and tasks.  
1588 6554 d 22 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 6554 d 23 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 6555 d 2 h jermar /kernel/trunk/generic/src/synch/ futex_cleanup() implementation.  
1585 6555 d 2 h jermar /kernel/trunk/generic/ Kill task when its main thread exits.  
1583 6555 d 6 h jermar /kernel/trunk/generic/ Make ktaskclnp call ipc_cleanup and futex_cleanup.  
1582 6555 d 6 h palkovsky /kernel/trunk/generic/ Modified ipc_cleanup.  
1581 6555 d 8 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 6555 d 9 h jermar /kernel/trunk/generic/src/ Update for task_kill().  
1579 6555 d 19 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 6555 d 21 h jermar /kernel/trunk/ Make use of thread_join_timeout() and thread_detach() in kernel.

Improved comments in slab.h.
 
1573 6555 d 23 h palkovsky /kernel/trunk/generic/ Renamed some things in IPC to be consistent.
Added ipc reporting to kconsole.
 
1571 6555 d 23 h jermar /kernel/trunk/generic/ thread_join_timeout() and thread_detach() implementation.
Needs more thorough testing.
 
1570 6556 d 0 h vana /kernel/trunk/arch/ia64/src/ski/ Ia64 keyboard extension  
1568 6556 d 1 h palkovsky /kernel/trunk/generic/ Slightly remodelled ipc hangups to facilitate correct cleanup.
Doc updates for frame allocator.
 
1554 6556 d 19 h jermar /kernel/trunk/generic/src/mm/ Improve comment in slab.c.  
1550 6557 d 0 h jermar /kernel/trunk/generic/src/mm/ Remove left over piece of code for increasing reference count in ELF backend.  
1549 6557 d 2 h vana /kernel/trunk/generic/src/adt/ Bitmap functions patch  
1548 6557 d 2 h vana /kernel/trunk/arch/ia64/src/ From/to kernel console switching on ia64  
1546 6557 d 2 h jermar /kernel/trunk/generic/src/mm/ Add reference to shared frames of ELF image backed address space area.  
1545 6557 d 2 h jermar /kernel/trunk/generic/src/mm/ Add reference to shared frames of anonymous address space area.  
1544 6557 d 2 h palkovsky /kernel/trunk/generic/ Slightly better behaviour with caching on memory sharing.  
1543 6557 d 6 h palkovsky /kernel/trunk/doc/ Note about mips bug making tetris to fail.  
1541 6557 d 8 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 6557 d 8 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 6557 d 9 h cejka /kernel/trunk/generic/src/mm/ Fixed warning about unused variable in non-debug mode.  
1537 6557 d 16 h palkovsky /kernel/trunk/ Added tetris to  
1527 6557 d 22 h jermar /kernel/trunk/contrib/conf/ Enable loading of kbd userspace driver in Ski sample configuration file.  
1511 6558 d 2 h palkovsky /kernel/trunk/arch/ Remove __address from include file included by uspace  
1507 6558 d 3 h vana /kernel/trunk/ IA64 uspace keyboard kernel part  
1502 6558 d 4 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.
