1682 6594 d 1 h palkovsky /kernel/trunk/ Fast framebuffer scrolling in kconsole. Eats some memory though.  
1681 6594 d 9 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 6594 d 9 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 6594 d 18 h palkovsky /kernel/trunk/generic/src/mm/ Fixed error in page number computing, that could almost never appear.  
1676 6594 d 19 h jermar /kernel/trunk/generic/src/proc/ Forgotten interrupts_restore().  
1669 6595 d 16 h palkovsky /kernel/trunk/generic/src/ipc/ Small consitency ipc update.  
1667 6595 d 16 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 6595 d 19 h palkovsky /kernel/trunk/ Slightly better test.
Made call keys work on ia64.
 
1662 6595 d 23 h palkovsky /kernel/trunk/generic/src/main/ Responsive kconsole after test finished.  
1661 6596 d 0 h jermar /kernel/trunk/generic/ Collect Undead threads while waiting to join uinit.
Rename ktaskkill to ktaskgc.
 
1659 6596 d 0 h vana /kernel/trunk/generic/src/main/ No uspace if tests  
1643 6596 d 22 h palkovsky /kernel/trunk/generic/ IPC made faster in non-debug mode.  
1636 6597 d 8 h jermar /kernel/trunk/ Move comment.

Do TLB shootdown also when allocating new ASID.
 
1628 6597 d 9 h decky /kernel/trunk/ fixes  
1625 6597 d 10 h decky /kernel/trunk/ ppc32 uspace keyboard support  
1613 6597 d 17 h palkovsky /kernel/trunk/generic/src/console/ Fixed klog to use correct vsnprintf.  
1612 6597 d 17 h jermar /kernel/trunk/generic/src/lib/ Generic version of memcpy that is resistent towards unaligned memory accesses.  
1605 6597 d 21 h cejka /kernel/trunk/generic/src/printf/ Another kernel printf return value fix.  
1604 6597 d 21 h cejka /kernel/trunk/ Fixed printf return value.  
1600 6598 d 0 h jermar /kernel/trunk/generic/src/proc/ Prevent task killing of kernel by returning EPERM on such a request.  
1599 6598 d 0 h palkovsky /kernel/trunk/generic/src/mm/ Blacklist first frame to avoid problems with allocator.  
1597 6598 d 0 h palkovsky /kernel/trunk/ Added possibility to interrupt task at exit from interrupt routine.  
1595 6598 d 1 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 6598 d 8 h jermar /kernel/trunk/generic/src/mm/ Never ever walk a B+tree as you destroy it. Or vice versa.  
1593 6598 d 9 h jermar /kernel/trunk/generic/src/synch/ When interrupted from sleep, pending timeouts must be unregistered.  
1591 6598 d 10 h palkovsky /kernel/trunk/generic/ Small updates to ipc.  
1589 6598 d 14 h jermar /kernel/trunk/generic/src/ Improve comments regarding liveliness of threads and tasks.  
1588 6598 d 14 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 6598 d 15 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 6598 d 18 h jermar /kernel/trunk/generic/src/synch/ futex_cleanup() implementation.  
1585 6598 d 18 h jermar /kernel/trunk/generic/ Kill task when its main thread exits.  
1583 6598 d 22 h jermar /kernel/trunk/generic/ Make ktaskclnp call ipc_cleanup and futex_cleanup.  
1582 6598 d 22 h palkovsky /kernel/trunk/generic/ Modified ipc_cleanup.  
1581 6599 d 0 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 6599 d 1 h jermar /kernel/trunk/generic/src/ Update for task_kill().  
1579 6599 d 11 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 6599 d 13 h jermar /kernel/trunk/ Make use of thread_join_timeout() and thread_detach() in kernel.

Improved comments in slab.h.
 
1573 6599 d 15 h palkovsky /kernel/trunk/generic/ Renamed some things in IPC to be consistent.
Added ipc reporting to kconsole.
 
1571 6599 d 15 h jermar /kernel/trunk/generic/ thread_join_timeout() and thread_detach() implementation.
Needs more thorough testing.
 
1568 6599 d 17 h palkovsky /kernel/trunk/generic/ Slightly remodelled ipc hangups to facilitate correct cleanup.
Doc updates for frame allocator.
