1702 6680 d 6 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1700 6680 d 9 h palkovsky /kernel/trunk/generic/src/mm/ Fixed frame allocator to allocate correct number of frames for configuration.
(It couldn't fail before, but in some circumstances it could allocate more
then needed).
 
1698 6681 d 0 h jermar /kernel/trunk/generic/src/ipc/ Improve comments.
Replace 'process' with 'task'.
 
1695 6682 d 3 h jermar /kernel/trunk/generic/src/console/ Inform the user about the kernel relinquishing the console on continue command.  
1693 6682 d 3 h palkovsky /kernel/trunk/generic/ Modified ipc/irq to be able to pass up to 3 arguments to userspace.  
1687 6683 d 7 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 6683 d 10 h jermar /kernel/trunk/ #ifdef more debugging printf()'s.  
1682 6683 d 13 h palkovsky /kernel/trunk/ Fast framebuffer scrolling in kconsole. Eats some memory though.  
1681 6683 d 21 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 6683 d 21 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 6684 d 6 h palkovsky /kernel/trunk/generic/src/mm/ Fixed error in page number computing, that could almost never appear.  
1676 6684 d 7 h jermar /kernel/trunk/generic/src/proc/ Forgotten interrupts_restore().  
1669 6685 d 3 h palkovsky /kernel/trunk/generic/src/ipc/ Small consitency ipc update.  
1667 6685 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 6685 d 7 h palkovsky /kernel/trunk/ Slightly better test.
Made call keys work on ia64.
 
1662 6685 d 11 h palkovsky /kernel/trunk/generic/src/main/ Responsive kconsole after test finished.  
1661 6685 d 11 h jermar /kernel/trunk/generic/ Collect Undead threads while waiting to join uinit.
Rename ktaskkill to ktaskgc.
 
1659 6685 d 12 h vana /kernel/trunk/generic/src/main/ No uspace if tests  
1643 6686 d 9 h palkovsky /kernel/trunk/generic/ IPC made faster in non-debug mode.  
1636 6686 d 20 h jermar /kernel/trunk/ Move comment.

Do TLB shootdown also when allocating new ASID.
 
1628 6686 d 21 h decky /kernel/trunk/ fixes  
1625 6686 d 21 h decky /kernel/trunk/ ppc32 uspace keyboard support  
1613 6687 d 5 h palkovsky /kernel/trunk/generic/src/console/ Fixed klog to use correct vsnprintf.  
1612 6687 d 5 h jermar /kernel/trunk/generic/src/lib/ Generic version of memcpy that is resistent towards unaligned memory accesses.  
1605 6687 d 8 h cejka /kernel/trunk/generic/src/printf/ Another kernel printf return value fix.  
1604 6687 d 9 h cejka /kernel/trunk/ Fixed printf return value.  
1600 6687 d 12 h jermar /kernel/trunk/generic/src/proc/ Prevent task killing of kernel by returning EPERM on such a request.  
1599 6687 d 12 h palkovsky /kernel/trunk/generic/src/mm/ Blacklist first frame to avoid problems with allocator.  
1597 6687 d 12 h palkovsky /kernel/trunk/ Added possibility to interrupt task at exit from interrupt routine.  
1595 6687 d 13 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 6687 d 19 h jermar /kernel/trunk/generic/src/mm/ Never ever walk a B+tree as you destroy it. Or vice versa.  
1593 6687 d 21 h jermar /kernel/trunk/generic/src/synch/ When interrupted from sleep, pending timeouts must be unregistered.  
1591 6687 d 22 h palkovsky /kernel/trunk/generic/ Small updates to ipc.  
1589 6688 d 2 h jermar /kernel/trunk/generic/src/ Improve comments regarding liveliness of threads and tasks.  
1588 6688 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 6688 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 6688 d 6 h jermar /kernel/trunk/generic/src/synch/ futex_cleanup() implementation.  
1585 6688 d 6 h jermar /kernel/trunk/generic/ Kill task when its main thread exits.  
1583 6688 d 9 h jermar /kernel/trunk/generic/ Make ktaskclnp call ipc_cleanup and futex_cleanup.  
1582 6688 d 10 h palkovsky /kernel/trunk/generic/ Modified ipc_cleanup.
