1595 6576 d 15 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 6576 d 22 h jermar /kernel/trunk/generic/src/mm/ Never ever walk a B+tree as you destroy it. Or vice versa.  
1593 6576 d 23 h jermar /kernel/trunk/generic/src/synch/ When interrupted from sleep, pending timeouts must be unregistered.  
1591 6577 d 1 h palkovsky /kernel/trunk/generic/ Small updates to ipc.  
1589 6577 d 4 h jermar /kernel/trunk/generic/src/ Improve comments regarding liveliness of threads and tasks.  
1588 6577 d 5 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 6577 d 5 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 6577 d 8 h jermar /kernel/trunk/generic/src/synch/ futex_cleanup() implementation.  
1585 6577 d 9 h jermar /kernel/trunk/generic/ Kill task when its main thread exits.  
1583 6577 d 12 h jermar /kernel/trunk/generic/ Make ktaskclnp call ipc_cleanup and futex_cleanup.  
1582 6577 d 12 h palkovsky /kernel/trunk/generic/ Modified ipc_cleanup.  
1581 6577 d 15 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 6577 d 15 h jermar /kernel/trunk/generic/src/ Update for task_kill().  
1579 6578 d 1 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 6578 d 3 h jermar /kernel/trunk/ Make use of thread_join_timeout() and thread_detach() in kernel.

Improved comments in slab.h.
 
1573 6578 d 6 h palkovsky /kernel/trunk/generic/ Renamed some things in IPC to be consistent.
Added ipc reporting to kconsole.
 
1571 6578 d 6 h jermar /kernel/trunk/generic/ thread_join_timeout() and thread_detach() implementation.
Needs more thorough testing.
 
1570 6578 d 6 h vana /kernel/trunk/arch/ia64/src/ski/ Ia64 keyboard extension  
1568 6578 d 7 h palkovsky /kernel/trunk/generic/ Slightly remodelled ipc hangups to facilitate correct cleanup.
Doc updates for frame allocator.
 
1554 6579 d 1 h jermar /kernel/trunk/generic/src/mm/ Improve comment in slab.c.  
1550 6579 d 7 h jermar /kernel/trunk/generic/src/mm/ Remove left over piece of code for increasing reference count in ELF backend.  
1549 6579 d 8 h vana /kernel/trunk/generic/src/adt/ Bitmap functions patch  
1548 6579 d 8 h vana /kernel/trunk/arch/ia64/src/ From/to kernel console switching on ia64  
1546 6579 d 8 h jermar /kernel/trunk/generic/src/mm/ Add reference to shared frames of ELF image backed address space area.  
1545 6579 d 9 h jermar /kernel/trunk/generic/src/mm/ Add reference to shared frames of anonymous address space area.  
1544 6579 d 9 h palkovsky /kernel/trunk/generic/ Slightly better behaviour with caching on memory sharing.  
1543 6579 d 12 h palkovsky /kernel/trunk/doc/ Note about mips bug making tetris to fail.  
1541 6579 d 14 h jermar /kernel/trunk/ Modify ia64 to load 6 userspace tasks.
Tetris however makes the kernel fault on unaligned memory access in copy_from_uspace.
 
1540 6579 d 15 h jermar /kernel/trunk/arch/ia32/src/smp/ Fix programming of local APIC timer to interrupt the processor
in the proper relation to HZ. (Was hardcoded to be each 1ms,
but should have been each 10ms).
 
1539 6579 d 15 h cejka /kernel/trunk/generic/src/mm/ Fixed warning about unused variable in non-debug mode.  
1537 6579 d 22 h palkovsky /kernel/trunk/ Added tetris to  
1527 6580 d 4 h jermar /kernel/trunk/contrib/conf/ Enable loading of kbd userspace driver in Ski sample configuration file.  
1511 6580 d 8 h palkovsky /kernel/trunk/arch/ Remove __address from include file included by uspace  
1507 6580 d 9 h vana /kernel/trunk/ IA64 uspace keyboard kernel part  
1502 6580 d 10 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.

1496 6580 d 22 h jermar /kernel/trunk/contrib/conf/ ski.conf for 4 ELF images.
kbd is commented out.
 
1495 6580 d 22 h jermar /kernel/trunk/ Remove three infinite loops introduced yesterday :-)

Make ia64 ready to load 5 ELF images.
 
1494 6580 d 22 h palkovsky /kernel/trunk/generic/ Removes unnecessary parameter for map_physmem syscall.  
1491 6581 d 0 h palkovsky /kernel/trunk/contrib/conf/ Msim configuration to load necessary modules to make it 'work' again.  
1488 6581 d 5 h vana /kernel/trunk/arch/ia64/include/ Lost file
