1760 6566 d 2 h palkovsky /kernel/trunk/ Changed interface of frame_alloc/free to use address of frame instead of the pfn.
This makes it impossible to use >4GB of memory on 32-bit machines, but who cares...
 
1757 6569 d 6 h jermar /kernel/trunk/ Cleanup of comments.  
1735 6571 d 7 h decky /kernel/trunk/ make kernel prints case consistent  
1708 6573 d 7 h jermar /kernel/trunk/ Fix some broken doxygen comments.  
1705 6575 d 7 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 6576 d 4 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1687 6579 d 5 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 6579 d 8 h jermar /kernel/trunk/ #ifdef more debugging printf()'s.  
1680 6579 d 18 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 6580 d 5 h jermar /kernel/trunk/generic/src/proc/ Forgotten interrupts_restore().  
1661 6581 d 9 h jermar /kernel/trunk/generic/ Collect Undead threads while waiting to join uinit.
Rename ktaskkill to ktaskgc.
 
1636 6582 d 18 h jermar /kernel/trunk/ Move comment.

Do TLB shootdown also when allocating new ASID.
 
1600 6583 d 9 h jermar /kernel/trunk/generic/src/proc/ Prevent task killing of kernel by returning EPERM on such a request.  
1597 6583 d 10 h palkovsky /kernel/trunk/ Added possibility to interrupt task at exit from interrupt routine.  
1595 6583 d 11 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 6584 d 0 h jermar /kernel/trunk/generic/src/ Improve comments regarding liveliness of threads and tasks.  
1588 6584 d 0 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 6584 d 1 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 6584 d 4 h jermar /kernel/trunk/generic/ Kill task when its main thread exits.  
1583 6584 d 7 h jermar /kernel/trunk/generic/ Make ktaskclnp call ipc_cleanup and futex_cleanup.  
1581 6584 d 10 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 6584 d 11 h jermar /kernel/trunk/generic/src/ Update for task_kill().  
1579 6584 d 20 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 6584 d 23 h jermar /kernel/trunk/ Make use of thread_join_timeout() and thread_detach() in kernel.

Improved comments in slab.h.
 
1573 6585 d 1 h palkovsky /kernel/trunk/generic/ Renamed some things in IPC to be consistent.
Added ipc reporting to kconsole.
 
1571 6585 d 1 h jermar /kernel/trunk/generic/ thread_join_timeout() and thread_detach() implementation.
Needs more thorough testing.
 
1502 6587 d 6 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 6589 d 2 h jermar /kernel/trunk/ Function for destroying address space for which there is no other reference in the kernel.  
1460 6589 d 6 h jermar /kernel/trunk/generic/ Reference counting for futexes.  
1458 6589 d 20 h palkovsky /kernel/trunk/ Added console support to gxemul.
Wider information in thread list.
 
1424 6593 d 1 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 6596 d 19 h jermar /kernel/trunk/generic/ Some shared memory stuff (not completed).
Support for address space area backends.
Add ELF and anonymous memory backends.
 
1380 6599 d 23 h jermar /kernel/trunk/ Turn address space lock, address space area lock and
page_ht_lock into mutexes.
 
1358 6604 d 1 h jermar /kernel/trunk/generic/ Cleanup after removal of as_area_accept and as_area_send.  
1288 6615 d 6 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 6619 d 6 h jermar /kernel/trunk/generic/ Improve Doxygen-comments.  
1248 6623 d 1 h jermar /kernel/trunk/ Add some @file doxygen comments and improve already existing comments.  
1239 6624 d 0 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 6624 d 7 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 6626 d 5 h jermar /kernel/trunk/ Remove the outdated TODO file.
Improve doxygen comments here and there.
