1698 6589 d 22 h jermar /kernel/trunk/generic/src/ipc/ Improve comments.
Replace 'process' with 'task'.
 
1695 6591 d 0 h jermar /kernel/trunk/generic/src/console/ Inform the user about the kernel relinquishing the console on continue command.  
1693 6591 d 1 h palkovsky /kernel/trunk/generic/ Modified ipc/irq to be able to pass up to 3 arguments to userspace.  
1687 6592 d 4 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 6592 d 7 h jermar /kernel/trunk/ #ifdef more debugging printf()'s.  
1682 6592 d 10 h palkovsky /kernel/trunk/ Fast framebuffer scrolling in kconsole. Eats some memory though.  
1681 6592 d 18 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 6592 d 18 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 6593 d 3 h palkovsky /kernel/trunk/generic/src/mm/ Fixed error in page number computing, that could almost never appear.  
1676 6593 d 4 h jermar /kernel/trunk/generic/src/proc/ Forgotten interrupts_restore().  
1669 6594 d 1 h palkovsky /kernel/trunk/generic/src/ipc/ Small consitency ipc update.  
1667 6594 d 1 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 6594 d 4 h palkovsky /kernel/trunk/ Slightly better test.
Made call keys work on ia64.
 
1662 6594 d 8 h palkovsky /kernel/trunk/generic/src/main/ Responsive kconsole after test finished.  
1661 6594 d 9 h jermar /kernel/trunk/generic/ Collect Undead threads while waiting to join uinit.
Rename ktaskkill to ktaskgc.
 
1659 6594 d 9 h vana /kernel/trunk/generic/src/main/ No uspace if tests  
1643 6595 d 7 h palkovsky /kernel/trunk/generic/ IPC made faster in non-debug mode.  
1636 6595 d 17 h jermar /kernel/trunk/ Move comment.

Do TLB shootdown also when allocating new ASID.
 
1628 6595 d 18 h decky /kernel/trunk/ fixes  
1625 6595 d 19 h decky /kernel/trunk/ ppc32 uspace keyboard support  
1613 6596 d 2 h palkovsky /kernel/trunk/generic/src/console/ Fixed klog to use correct vsnprintf.  
1612 6596 d 2 h jermar /kernel/trunk/generic/src/lib/ Generic version of memcpy that is resistent towards unaligned memory accesses.  
1605 6596 d 6 h cejka /kernel/trunk/generic/src/printf/ Another kernel printf return value fix.  
1604 6596 d 6 h cejka /kernel/trunk/ Fixed printf return value.  
1600 6596 d 9 h jermar /kernel/trunk/generic/src/proc/ Prevent task killing of kernel by returning EPERM on such a request.  
1599 6596 d 9 h palkovsky /kernel/trunk/generic/src/mm/ Blacklist first frame to avoid problems with allocator.  
1597 6596 d 9 h palkovsky /kernel/trunk/ Added possibility to interrupt task at exit from interrupt routine.  
1595 6596 d 10 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 6596 d 17 h jermar /kernel/trunk/generic/src/mm/ Never ever walk a B+tree as you destroy it. Or vice versa.  
1593 6596 d 18 h jermar /kernel/trunk/generic/src/synch/ When interrupted from sleep, pending timeouts must be unregistered.  
1591 6596 d 19 h palkovsky /kernel/trunk/generic/ Small updates to ipc.  
1589 6596 d 23 h jermar /kernel/trunk/generic/src/ Improve comments regarding liveliness of threads and tasks.  
1588 6596 d 23 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 6597 d 0 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 6597 d 3 h jermar /kernel/trunk/generic/src/synch/ futex_cleanup() implementation.  
1585 6597 d 3 h jermar /kernel/trunk/generic/ Kill task when its main thread exits.  
1583 6597 d 7 h jermar /kernel/trunk/generic/ Make ktaskclnp call ipc_cleanup and futex_cleanup.  
1582 6597 d 7 h palkovsky /kernel/trunk/generic/ Modified ipc_cleanup.  
1581 6597 d 9 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 6597 d 10 h jermar /kernel/trunk/generic/src/ Update for task_kill().
