1682 6646 d 12 h palkovsky /kernel/trunk/ Fast framebuffer scrolling in kconsole. Eats some memory though.  
1681 6646 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 6646 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 6647 d 6 h palkovsky /kernel/trunk/generic/src/mm/ Fixed error in page number computing, that could almost never appear.  
1676 6647 d 6 h jermar /kernel/trunk/generic/src/proc/ Forgotten interrupts_restore().  
1669 6648 d 3 h palkovsky /kernel/trunk/generic/src/ipc/ Small consitency ipc update.  
1667 6648 d 4 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 6648 d 7 h palkovsky /kernel/trunk/ Slightly better test.
Made call keys work on ia64.
 
1662 6648 d 11 h palkovsky /kernel/trunk/generic/src/main/ Responsive kconsole after test finished.  
1661 6648 d 11 h jermar /kernel/trunk/generic/ Collect Undead threads while waiting to join uinit.
Rename ktaskkill to ktaskgc.
 
1659 6648 d 11 h vana /kernel/trunk/generic/src/main/ No uspace if tests  
1643 6649 d 9 h palkovsky /kernel/trunk/generic/ IPC made faster in non-debug mode.  
1636 6649 d 19 h jermar /kernel/trunk/ Move comment.

Do TLB shootdown also when allocating new ASID.
 
1628 6649 d 21 h decky /kernel/trunk/ fixes  
1625 6649 d 21 h decky /kernel/trunk/ ppc32 uspace keyboard support  
1613 6650 d 4 h palkovsky /kernel/trunk/generic/src/console/ Fixed klog to use correct vsnprintf.  
1612 6650 d 4 h jermar /kernel/trunk/generic/src/lib/ Generic version of memcpy that is resistent towards unaligned memory accesses.  
1605 6650 d 8 h cejka /kernel/trunk/generic/src/printf/ Another kernel printf return value fix.  
1604 6650 d 8 h cejka /kernel/trunk/ Fixed printf return value.  
1600 6650 d 11 h jermar /kernel/trunk/generic/src/proc/ Prevent task killing of kernel by returning EPERM on such a request.  
1599 6650 d 11 h palkovsky /kernel/trunk/generic/src/mm/ Blacklist first frame to avoid problems with allocator.  
1597 6650 d 12 h palkovsky /kernel/trunk/ Added possibility to interrupt task at exit from interrupt routine.  
1595 6650 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 6650 d 19 h jermar /kernel/trunk/generic/src/mm/ Never ever walk a B+tree as you destroy it. Or vice versa.  
1593 6650 d 20 h jermar /kernel/trunk/generic/src/synch/ When interrupted from sleep, pending timeouts must be unregistered.  
1591 6650 d 22 h palkovsky /kernel/trunk/generic/ Small updates to ipc.  
1589 6651 d 1 h jermar /kernel/trunk/generic/src/ Improve comments regarding liveliness of threads and tasks.  
1588 6651 d 2 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 6651 d 3 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 6651 d 6 h jermar /kernel/trunk/generic/src/synch/ futex_cleanup() implementation.  
1585 6651 d 6 h jermar /kernel/trunk/generic/ Kill task when its main thread exits.  
1583 6651 d 9 h jermar /kernel/trunk/generic/ Make ktaskclnp call ipc_cleanup and futex_cleanup.  
1582 6651 d 9 h palkovsky /kernel/trunk/generic/ Modified ipc_cleanup.  
1581 6651 d 12 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 6651 d 12 h jermar /kernel/trunk/generic/src/ Update for task_kill().  
1579 6651 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 6652 d 0 h jermar /kernel/trunk/ Make use of thread_join_timeout() and thread_detach() in kernel.

Improved comments in slab.h.
 
1573 6652 d 3 h palkovsky /kernel/trunk/generic/ Renamed some things in IPC to be consistent.
Added ipc reporting to kconsole.
 
1571 6652 d 3 h jermar /kernel/trunk/generic/ thread_join_timeout() and thread_detach() implementation.
Needs more thorough testing.
 
1568 6652 d 4 h palkovsky /kernel/trunk/generic/ Slightly remodelled ipc hangups to facilitate correct cleanup.
Doc updates for frame allocator.
