1589 6628 d 6 h jermar /kernel/trunk/generic/src/ Improve comments regarding liveliness of threads and tasks.  
1588 6628 d 7 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 6628 d 8 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 6628 d 11 h jermar /kernel/trunk/generic/src/synch/ futex_cleanup() implementation.  
1585 6628 d 11 h jermar /kernel/trunk/generic/ Kill task when its main thread exits.  
1583 6628 d 14 h jermar /kernel/trunk/generic/ Make ktaskclnp call ipc_cleanup and futex_cleanup.  
1582 6628 d 15 h palkovsky /kernel/trunk/generic/ Modified ipc_cleanup.  
1581 6628 d 17 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 6628 d 17 h jermar /kernel/trunk/generic/src/ Update for task_kill().  
1579 6629 d 3 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 6629 d 5 h jermar /kernel/trunk/ Make use of thread_join_timeout() and thread_detach() in kernel.

Improved comments in slab.h.		  
1573 6629 d 8 h palkovsky /kernel/trunk/generic/ Renamed some things in IPC to be consistent.
Added ipc reporting to kconsole.		  
1571 6629 d 8 h jermar /kernel/trunk/generic/ thread_join_timeout() and thread_detach() implementation.
Needs more thorough testing.		  
1568 6629 d 9 h palkovsky /kernel/trunk/generic/ Slightly remodelled ipc hangups to facilitate correct cleanup.
Doc updates for frame allocator.		  
1554 6630 d 3 h jermar /kernel/trunk/generic/src/mm/ Improve comment in slab.c.  
1550 6630 d 9 h jermar /kernel/trunk/generic/src/mm/ Remove left over piece of code for increasing reference count in ELF backend.  
1549 6630 d 10 h vana /kernel/trunk/generic/src/adt/ Bitmap functions patch  
1546 6630 d 11 h jermar /kernel/trunk/generic/src/mm/ Add reference to shared frames of ELF image backed address space area.  
1545 6630 d 11 h jermar /kernel/trunk/generic/src/mm/ Add reference to shared frames of anonymous address space area.  
1544 6630 d 11 h palkovsky /kernel/trunk/generic/ Slightly better behaviour with caching on memory sharing.  
1539 6630 d 17 h cejka /kernel/trunk/generic/src/mm/ Fixed warning about unused variable in non-debug mode.  
1507 6631 d 11 h vana /kernel/trunk/ IA64 uspace keyboard kernel part  
1502 6631 d 13 h jermar /kernel/trunk/ Replace nonblocking argument of waitq_sleep_timeout with flags that specify mode of operation.
Now a flag can be used to specify interruptible sleep.
Modify waitq_interrupt_sleep() to only interrupt threads that used this flag.
O		  
1495 6632 d 0 h jermar /kernel/trunk/ Remove three infinite loops introduced yesterday :-)

Make ia64 ready to load 5 ELF images.		  
1494 6632 d 1 h palkovsky /kernel/trunk/generic/ Removes unnecessary parameter for map_physmem syscall.  
1483 6632 d 11 h jermar /kernel/trunk/generic/src/ Implement recursive function for deallocating the whole B+tree.
Make use of this function in address space management.		  
1474 6633 d 3 h palkovsky /kernel/trunk/ Added syscall that lets kernel regain access to keyboard.  
1468 6633 d 9 h jermar /kernel/trunk/ Function for destroying address space for which there is no other reference in the kernel.  
1467 6633 d 9 h jermar /kernel/trunk/generic/src/synch/ Allow usage of blocking synchronization primitives in functions that are also called during system initialization.  
1461 6633 d 11 h palkovsky /kernel/trunk/generic/ Slightly changed semantics of AS_AREA_SEND/RECV.  
1460 6633 d 13 h jermar /kernel/trunk/generic/ Reference counting for futexes.  
1458 6634 d 3 h palkovsky /kernel/trunk/ Added console support to gxemul.
Wider information in thread list.		  
1457 6634 d 3 h jermar /kernel/trunk/generic/src/time/ Project missed_clock_ticks also on thread timeslice and run queue relink counter.  
1448 6635 d 8 h palkovsky /kernel/trunk/generic/src/syscall/ Better SYS_IO  
1438 6636 d 3 h palkovsky /kernel/trunk/generic/ Correct realtime clock communication.  
1437 6636 d 4 h jermar /kernel/trunk/generic/src/mm/ Fix used_space_insert() to correctly service an empty used_space B+tree.  
1436 6636 d 5 h jermar /kernel/trunk/generic/src/mm/ Fight TLB inconsistency by proper placing of tlb_shootdown_start() and tlb_shootdown_finalize() in as.c.  
1434 6636 d 7 h palkovsky /kernel/trunk/ Added 'realtime' clock interface.
Added some asm macros as memory barriers.
Added drift computing for mips platform.		  
1433 6636 d 10 h jermar /kernel/trunk/generic/src/time/ Fix critical bug in timeout processing introduced several hours ago.  
1431 6636 d 14 h jermar /kernel/trunk/generic/ Add missed_clock_ticks to CPU structure so that clock() can detect missed timer interrupts.
Architectures are required to support this in order to make time keeping accurate.
