1687 6628 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 6628 d 9 h jermar /kernel/trunk/ #ifdef more debugging printf()'s.  
1682 6628 d 12 h palkovsky /kernel/trunk/ Fast framebuffer scrolling in kconsole. Eats some memory though.  
1681 6628 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 6628 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 6629 d 5 h palkovsky /kernel/trunk/generic/src/mm/ Fixed error in page number computing, that could almost never appear.  
1676 6629 d 6 h jermar /kernel/trunk/generic/src/proc/ Forgotten interrupts_restore().  
1669 6630 d 3 h palkovsky /kernel/trunk/generic/src/ipc/ Small consitency ipc update.  
1667 6630 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 6630 d 6 h palkovsky /kernel/trunk/ Slightly better test.
Made call keys work on ia64.
 
1662 6630 d 11 h palkovsky /kernel/trunk/generic/src/main/ Responsive kconsole after test finished.  
1661 6630 d 11 h jermar /kernel/trunk/generic/ Collect Undead threads while waiting to join uinit.
Rename ktaskkill to ktaskgc.
 
1659 6630 d 11 h vana /kernel/trunk/generic/src/main/ No uspace if tests  
1643 6631 d 9 h palkovsky /kernel/trunk/generic/ IPC made faster in non-debug mode.  
1636 6631 d 19 h jermar /kernel/trunk/ Move comment.

Do TLB shootdown also when allocating new ASID.
 
1628 6631 d 20 h decky /kernel/trunk/ fixes  
1625 6631 d 21 h decky /kernel/trunk/ ppc32 uspace keyboard support  
1613 6632 d 4 h palkovsky /kernel/trunk/generic/src/console/ Fixed klog to use correct vsnprintf.  
1612 6632 d 4 h jermar /kernel/trunk/generic/src/lib/ Generic version of memcpy that is resistent towards unaligned memory accesses.  
1605 6632 d 8 h cejka /kernel/trunk/generic/src/printf/ Another kernel printf return value fix.  
1604 6632 d 8 h cejka /kernel/trunk/ Fixed printf return value.  
1600 6632 d 11 h jermar /kernel/trunk/generic/src/proc/ Prevent task killing of kernel by returning EPERM on such a request.  
1599 6632 d 11 h palkovsky /kernel/trunk/generic/src/mm/ Blacklist first frame to avoid problems with allocator.  
1597 6632 d 11 h palkovsky /kernel/trunk/ Added possibility to interrupt task at exit from interrupt routine.  
1595 6632 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 6632 d 19 h jermar /kernel/trunk/generic/src/mm/ Never ever walk a B+tree as you destroy it. Or vice versa.  
1593 6632 d 20 h jermar /kernel/trunk/generic/src/synch/ When interrupted from sleep, pending timeouts must be unregistered.  
1591 6632 d 21 h palkovsky /kernel/trunk/generic/ Small updates to ipc.  
1589 6633 d 1 h jermar /kernel/trunk/generic/src/ Improve comments regarding liveliness of threads and tasks.  
1588 6633 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 6633 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 6633 d 5 h jermar /kernel/trunk/generic/src/synch/ futex_cleanup() implementation.  
1585 6633 d 6 h jermar /kernel/trunk/generic/ Kill task when its main thread exits.  
1583 6633 d 9 h jermar /kernel/trunk/generic/ Make ktaskclnp call ipc_cleanup and futex_cleanup.  
1582 6633 d 9 h palkovsky /kernel/trunk/generic/ Modified ipc_cleanup.  
1581 6633 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 6633 d 12 h jermar /kernel/trunk/generic/src/ Update for task_kill().  
1579 6633 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.
 
1576 6634 d 0 h jermar /kernel/trunk/ Make use of thread_join_timeout() and thread_detach() in kernel.

Improved comments in slab.h.
 
1573 6634 d 2 h palkovsky /kernel/trunk/generic/ Renamed some things in IPC to be consistent.
Added ipc reporting to kconsole.
