1708 6563 d 22 h jermar /kernel/trunk/ Fix some broken doxygen comments.  
1705 6565 d 22 h cejka /kernel/trunk/ Added file with modules definitions and descriptions.
We are able to change modules order and their description in one place.
 
1702 6566 d 19 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1687 6569 d 20 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 6569 d 23 h jermar /kernel/trunk/ #ifdef more debugging printf()'s.  
1680 6570 d 10 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().
 
1676 6570 d 20 h jermar /kernel/trunk/generic/src/proc/ Forgotten interrupts_restore().  
1661 6572 d 1 h jermar /kernel/trunk/generic/ Collect Undead threads while waiting to join uinit.
Rename ktaskkill to ktaskgc.
 
1636 6573 d 9 h jermar /kernel/trunk/ Move comment.

Do TLB shootdown also when allocating new ASID.
 
1600 6574 d 1 h jermar /kernel/trunk/generic/src/proc/ Prevent task killing of kernel by returning EPERM on such a request.  
1597 6574 d 1 h palkovsky /kernel/trunk/ Added possibility to interrupt task at exit from interrupt routine.  
1595 6574 d 2 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.
 
1589 6574 d 15 h jermar /kernel/trunk/generic/src/ Improve comments regarding liveliness of threads and tasks.  
1588 6574 d 15 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 6574 d 16 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.
 
1585 6574 d 19 h jermar /kernel/trunk/generic/ Kill task when its main thread exits.  
1583 6574 d 23 h jermar /kernel/trunk/generic/ Make ktaskclnp call ipc_cleanup and futex_cleanup.  
1581 6575 d 1 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 6575 d 2 h jermar /kernel/trunk/generic/src/ Update for task_kill().  
1579 6575 d 12 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 6575 d 14 h jermar /kernel/trunk/ Make use of thread_join_timeout() and thread_detach() in kernel.

Improved comments in slab.h.
 
1573 6575 d 16 h palkovsky /kernel/trunk/generic/ Renamed some things in IPC to be consistent.
Added ipc reporting to kconsole.
 
1571 6575 d 16 h jermar /kernel/trunk/generic/ thread_join_timeout() and thread_detach() implementation.
Needs more thorough testing.
 
1502 6577 d 21 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
 
1468 6579 d 17 h jermar /kernel/trunk/ Function for destroying address space for which there is no other reference in the kernel.  
1460 6579 d 21 h jermar /kernel/trunk/generic/ Reference counting for futexes.  
1458 6580 d 11 h palkovsky /kernel/trunk/ Added console support to gxemul.
Wider information in thread list.
 
1424 6583 d 16 h jermar /kernel/trunk/ Move the sharing functionality to address space area backends.
Add backend for continuous regions of physical memory.
Sharing for these areas works automagically now.
 
1409 6587 d 10 h jermar /kernel/trunk/generic/ Some shared memory stuff (not completed).
Support for address space area backends.
Add ELF and anonymous memory backends.
 
1380 6590 d 14 h jermar /kernel/trunk/ Turn address space lock, address space area lock and
page_ht_lock into mutexes.
 
1358 6594 d 16 h jermar /kernel/trunk/generic/ Cleanup after removal of as_area_accept and as_area_send.  
1288 6605 d 22 h jermar /kernel/trunk/ Complete implementation of copy_from_uspace() and copy_to_uspace()
for amd64 and ia32. Other architectures still compile and run,
but need to implement their own assembly-only memcpy(), memcpy_from_uspace(),
memcpy_to_uspace() and their failover parts. For these architectures
only dummy implementations are provided.
 
1264 6609 d 21 h jermar /kernel/trunk/generic/ Improve Doxygen-comments.  
1248 6613 d 16 h jermar /kernel/trunk/ Add some @file doxygen comments and improve already existing comments.  
1239 6614 d 16 h jermar /kernel/trunk/generic/ Prevent race in as_area_send() by allowing the address space area to be
created with AS_AREA_ATTR_PARTIAL attribute.
 
1235 6614 d 22 h jermar /kernel/trunk/generic/ Implementation of SYS_AS_AREA_ACCEPT and SYS_AS_AREA_SEND syscalls.
Note that these replace previously declared SYS_AS_AREA_SHARE_APPROVE
and SYS_AS_AREA_SHARE_PERFORM.
 
1229 6616 d 21 h jermar /kernel/trunk/ Remove the outdated TODO file.
Improve doxygen comments here and there.
 
1227 6617 d 17 h jermar /kernel/trunk/ Reorganize syscall names to better correspond to kernel architecture.
Add dummy placeholders for SYS_AS_AREA_SHARE_APPROVE and
SYS_AS_AREA_SHARE_PERFORM syscalls.
 
1221 6618 d 11 h decky /kernel/trunk/ printf-related and other code cleanup  
1210 6619 d 21 h vana /kernel/trunk/ Incomplete VHPT walker support for Itanium
