1695 6589 d 2 h jermar /kernel/trunk/generic/src/console/ Inform the user about the kernel relinquishing the console on continue command.  
1693 6589 d 3 h palkovsky /kernel/trunk/generic/ Modified ipc/irq to be able to pass up to 3 arguments to userspace.  
1687 6590 d 6 h jermar /kernel/trunk/generic/src/proc/ Fix double thread_join() in ktaskgc.
In thread_create(), lock TASK with interrupts disabled again.
thread_join_timeout() can use ordinary waitq_sleep_timeout().
 
1684 6590 d 9 h jermar /kernel/trunk/ #ifdef more debugging printf()'s.  
1682 6590 d 12 h palkovsky /kernel/trunk/ Fast framebuffer scrolling in kconsole. Eats some memory though.  
1681 6590 d 20 h jermar /kernel/trunk/generic/src/synch/ Avoid tricky race condition between waitq_wakeup() and the pair
of waitq_timeouted_sleep() and waitq_interrupt_sleep().
Mutual exclusion != Synchronization.
 
1680 6590 d 20 h jermar /kernel/trunk/generic/src/proc/ Add interrupts_restore() to thread_join_timeout(). Note that this is not necessary, because
waitq_sleep_finish() does the job for thread_join_timeout(). However, the code looks more
correct in the form with interrupts_restore().
 
1677 6591 d 5 h palkovsky /kernel/trunk/generic/src/mm/ Fixed error in page number computing, that could almost never appear.  
1676 6591 d 6 h jermar /kernel/trunk/generic/src/proc/ Forgotten interrupts_restore().  
1669 6592 d 3 h palkovsky /kernel/trunk/generic/src/ipc/ Small consitency ipc update.  
1667 6592 d 3 h jermar /kernel/trunk/ Print spurious interrupt messages only when compiled with CONFIG_DEBUG.
Print warning about looping spinlock only after 100000000 unsuccessfull attempts to gain the spinlock.
 
1666 6592 d 6 h palkovsky /kernel/trunk/ Slightly better test.
Made call keys work on ia64.
 
1662 6592 d 10 h palkovsky /kernel/trunk/generic/src/main/ Responsive kconsole after test finished.  
1661 6592 d 11 h jermar /kernel/trunk/generic/ Collect Undead threads while waiting to join uinit.
Rename ktaskkill to ktaskgc.
 
1659 6592 d 11 h vana /kernel/trunk/generic/src/main/ No uspace if tests  
1643 6593 d 9 h palkovsky /kernel/trunk/generic/ IPC made faster in non-debug mode.  
1636 6593 d 19 h jermar /kernel/trunk/ Move comment.

Do TLB shootdown also when allocating new ASID.
 
1628 6593 d 20 h decky /kernel/trunk/ fixes  
1625 6593 d 21 h decky /kernel/trunk/ ppc32 uspace keyboard support  
1613 6594 d 4 h palkovsky /kernel/trunk/generic/src/console/ Fixed klog to use correct vsnprintf.  
1612 6594 d 4 h jermar /kernel/trunk/generic/src/lib/ Generic version of memcpy that is resistent towards unaligned memory accesses.  
1605 6594 d 8 h cejka /kernel/trunk/generic/src/printf/ Another kernel printf return value fix.  
1604 6594 d 8 h cejka /kernel/trunk/ Fixed printf return value.  
1600 6594 d 11 h jermar /kernel/trunk/generic/src/proc/ Prevent task killing of kernel by returning EPERM on such a request.  
1599 6594 d 11 h palkovsky /kernel/trunk/generic/src/mm/ Blacklist first frame to avoid problems with allocator.  
1597 6594 d 11 h palkovsky /kernel/trunk/ Added possibility to interrupt task at exit from interrupt routine.  
1595 6594 d 12 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 6594 d 19 h jermar /kernel/trunk/generic/src/mm/ Never ever walk a B+tree as you destroy it. Or vice versa.  
1593 6594 d 20 h jermar /kernel/trunk/generic/src/synch/ When interrupted from sleep, pending timeouts must be unregistered.  
1591 6594 d 21 h palkovsky /kernel/trunk/generic/ Small updates to ipc.  
1589 6595 d 1 h jermar /kernel/trunk/generic/src/ Improve comments regarding liveliness of threads and tasks.  
1588 6595 d 1 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 6595 d 2 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 6595 d 5 h jermar /kernel/trunk/generic/src/synch/ futex_cleanup() implementation.  
1585 6595 d 5 h jermar /kernel/trunk/generic/ Kill task when its main thread exits.  
1583 6595 d 9 h jermar /kernel/trunk/generic/ Make ktaskclnp call ipc_cleanup and futex_cleanup.  
1582 6595 d 9 h palkovsky /kernel/trunk/generic/ Modified ipc_cleanup.  
1581 6595 d 11 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 6595 d 12 h jermar /kernel/trunk/generic/src/ Update for task_kill().  
1579 6595 d 22 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.
