1682 6644 d 21 h palkovsky /kernel/trunk/ Fast framebuffer scrolling in kconsole. Eats some memory though.  
1681 6645 d 5 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 6645 d 5 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 6645 d 14 h palkovsky /kernel/trunk/generic/src/mm/ Fixed error in page number computing, that could almost never appear.  
1676 6645 d 15 h jermar /kernel/trunk/generic/src/proc/ Forgotten interrupts_restore().  
1669 6646 d 11 h palkovsky /kernel/trunk/generic/src/ipc/ Small consitency ipc update.  
1667 6646 d 12 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 6646 d 15 h palkovsky /kernel/trunk/ Slightly better test.
Made call keys work on ia64.
 
1662 6646 d 19 h palkovsky /kernel/trunk/generic/src/main/ Responsive kconsole after test finished.  
1661 6646 d 19 h jermar /kernel/trunk/generic/ Collect Undead threads while waiting to join uinit.
Rename ktaskkill to ktaskgc.
 
1659 6646 d 20 h vana /kernel/trunk/generic/src/main/ No uspace if tests  
1643 6647 d 18 h palkovsky /kernel/trunk/generic/ IPC made faster in non-debug mode.  
1636 6648 d 4 h jermar /kernel/trunk/ Move comment.

Do TLB shootdown also when allocating new ASID.
 
1628 6648 d 5 h decky /kernel/trunk/ fixes  
1625 6648 d 5 h decky /kernel/trunk/ ppc32 uspace keyboard support  
1613 6648 d 13 h palkovsky /kernel/trunk/generic/src/console/ Fixed klog to use correct vsnprintf.  
1612 6648 d 13 h jermar /kernel/trunk/generic/src/lib/ Generic version of memcpy that is resistent towards unaligned memory accesses.  
1605 6648 d 17 h cejka /kernel/trunk/generic/src/printf/ Another kernel printf return value fix.  
1604 6648 d 17 h cejka /kernel/trunk/ Fixed printf return value.  
1600 6648 d 20 h jermar /kernel/trunk/generic/src/proc/ Prevent task killing of kernel by returning EPERM on such a request.  
1599 6648 d 20 h palkovsky /kernel/trunk/generic/src/mm/ Blacklist first frame to avoid problems with allocator.  
1597 6648 d 20 h palkovsky /kernel/trunk/ Added possibility to interrupt task at exit from interrupt routine.  
1595 6648 d 21 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 6649 d 3 h jermar /kernel/trunk/generic/src/mm/ Never ever walk a B+tree as you destroy it. Or vice versa.  
1593 6649 d 5 h jermar /kernel/trunk/generic/src/synch/ When interrupted from sleep, pending timeouts must be unregistered.  
1591 6649 d 6 h palkovsky /kernel/trunk/generic/ Small updates to ipc.  
1589 6649 d 10 h jermar /kernel/trunk/generic/src/ Improve comments regarding liveliness of threads and tasks.  
1588 6649 d 10 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 6649 d 11 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 6649 d 14 h jermar /kernel/trunk/generic/src/synch/ futex_cleanup() implementation.  
1585 6649 d 14 h jermar /kernel/trunk/generic/ Kill task when its main thread exits.  
1583 6649 d 17 h jermar /kernel/trunk/generic/ Make ktaskclnp call ipc_cleanup and futex_cleanup.  
1582 6649 d 18 h palkovsky /kernel/trunk/generic/ Modified ipc_cleanup.  
1581 6649 d 20 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 6649 d 21 h jermar /kernel/trunk/generic/src/ Update for task_kill().  
1579 6650 d 7 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 6650 d 9 h jermar /kernel/trunk/ Make use of thread_join_timeout() and thread_detach() in kernel.

Improved comments in slab.h.
 
1573 6650 d 11 h palkovsky /kernel/trunk/generic/ Renamed some things in IPC to be consistent.
Added ipc reporting to kconsole.
 
1571 6650 d 11 h jermar /kernel/trunk/generic/ thread_join_timeout() and thread_detach() implementation.
Needs more thorough testing.
 
1568 6650 d 13 h palkovsky /kernel/trunk/generic/ Slightly remodelled ipc hangups to facilitate correct cleanup.
Doc updates for frame allocator.
