1687 6544 d 6 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 6544 d 10 h jermar /kernel/trunk/ #ifdef more debugging printf()'s.  
1680 6544 d 20 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 6545 d 6 h jermar /kernel/trunk/generic/src/proc/ Forgotten interrupts_restore().  
1661 6546 d 11 h jermar /kernel/trunk/generic/ Collect Undead threads while waiting to join uinit.
Rename ktaskkill to ktaskgc.
 
1636 6547 d 19 h jermar /kernel/trunk/ Move comment.

Do TLB shootdown also when allocating new ASID.
 
1600 6548 d 11 h jermar /kernel/trunk/generic/src/proc/ Prevent task killing of kernel by returning EPERM on such a request.  
1597 6548 d 11 h palkovsky /kernel/trunk/ Added possibility to interrupt task at exit from interrupt routine.  
1595 6548 d 12 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 6549 d 1 h jermar /kernel/trunk/generic/src/ Improve comments regarding liveliness of threads and tasks.  
1588 6549 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 6549 d 2 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 6549 d 6 h jermar /kernel/trunk/generic/ Kill task when its main thread exits.  
1583 6549 d 9 h jermar /kernel/trunk/generic/ Make ktaskclnp call ipc_cleanup and futex_cleanup.  
1581 6549 d 12 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 6549 d 12 h jermar /kernel/trunk/generic/src/ Update for task_kill().  
1579 6549 d 22 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 6550 d 0 h jermar /kernel/trunk/ Make use of thread_join_timeout() and thread_detach() in kernel.

Improved comments in slab.h.
 
1573 6550 d 2 h palkovsky /kernel/trunk/generic/ Renamed some things in IPC to be consistent.
Added ipc reporting to kconsole.
 
1571 6550 d 3 h jermar /kernel/trunk/generic/ thread_join_timeout() and thread_detach() implementation.
Needs more thorough testing.
 
1502 6552 d 7 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 6554 d 3 h jermar /kernel/trunk/ Function for destroying address space for which there is no other reference in the kernel.  
1460 6554 d 7 h jermar /kernel/trunk/generic/ Reference counting for futexes.  
1458 6554 d 21 h palkovsky /kernel/trunk/ Added console support to gxemul.
Wider information in thread list.
 
1424 6558 d 2 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 6561 d 21 h jermar /kernel/trunk/generic/ Some shared memory stuff (not completed).
Support for address space area backends.
Add ELF and anonymous memory backends.
 
1380 6565 d 0 h jermar /kernel/trunk/ Turn address space lock, address space area lock and
page_ht_lock into mutexes.
 
1358 6569 d 3 h jermar /kernel/trunk/generic/ Cleanup after removal of as_area_accept and as_area_send.  
1288 6580 d 8 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 6584 d 7 h jermar /kernel/trunk/generic/ Improve Doxygen-comments.  
1248 6588 d 3 h jermar /kernel/trunk/ Add some @file doxygen comments and improve already existing comments.  
1239 6589 d 2 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 6589 d 8 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 6591 d 7 h jermar /kernel/trunk/ Remove the outdated TODO file.
Improve doxygen comments here and there.
 
1227 6592 d 4 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.

Printf calls changed to match new conventions.
 
1187 6602 d 2 h jermar /kernel/trunk/ Cleanup pm.c and pm.h code on ia32 and amd64.
Add before_task_runs() and before_task_runs_arch() for each architecture.
Add ia32 and amd64 code to ensure I/O Permission Bitmap update.
 
1185 6602 d 5 h jermar /kernel/trunk/ Add task_create_arch() for all architectures.
