1780 6512 d 23 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1757 6527 d 4 h jermar /kernel/trunk/ Cleanup of comments.  
1735 6529 d 5 h decky /kernel/trunk/ make kernel prints case consistent  
1702 6534 d 2 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1687 6537 d 2 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 6537 d 6 h jermar /kernel/trunk/ #ifdef more debugging printf()'s.  
1676 6538 d 3 h jermar /kernel/trunk/generic/src/proc/ Forgotten interrupts_restore().  
1661 6539 d 7 h jermar /kernel/trunk/generic/ Collect Undead threads while waiting to join uinit.
Rename ktaskkill to ktaskgc.		  
1636 6540 d 16 h jermar /kernel/trunk/ Move comment.

Do TLB shootdown also when allocating new ASID.		  
1600 6541 d 7 h jermar /kernel/trunk/generic/src/proc/ Prevent task killing of kernel by returning EPERM on such a request.  
1597 6541 d 8 h palkovsky /kernel/trunk/ Added possibility to interrupt task at exit from interrupt routine.  
1589 6541 d 21 h jermar /kernel/trunk/generic/src/ Improve comments regarding liveliness of threads and tasks.  
1588 6541 d 22 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 6541 d 23 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 6542 d 2 h jermar /kernel/trunk/generic/ Kill task when its main thread exits.  
1583 6542 d 5 h jermar /kernel/trunk/generic/ Make ktaskclnp call ipc_cleanup and futex_cleanup.  
1580 6542 d 8 h jermar /kernel/trunk/generic/src/ Update for task_kill().  
1579 6542 d 18 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.		  
1573 6542 d 23 h palkovsky /kernel/trunk/generic/ Renamed some things in IPC to be consistent.
Added ipc reporting to kconsole.		  
1468 6547 d 0 h jermar /kernel/trunk/ Function for destroying address space for which there is no other reference in the kernel.  
1460 6547 d 4 h jermar /kernel/trunk/generic/ Reference counting for futexes.  
1424 6550 d 22 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 6554 d 17 h jermar /kernel/trunk/generic/ Some shared memory stuff (not completed).
Support for address space area backends.
Add ELF and anonymous memory backends.		  
1358 6561 d 23 h jermar /kernel/trunk/generic/ Cleanup after removal of as_area_accept and as_area_send.  
1288 6573 d 4 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.		  
1248 6580 d 23 h jermar /kernel/trunk/ Add some @file doxygen comments and improve already existing comments.  
1239 6581 d 22 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 6582 d 4 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 6584 d 3 h jermar /kernel/trunk/ Remove the outdated TODO file.
Improve doxygen comments here and there.		  
1227 6585 d 0 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.		  
1196 6592 d 3 h cejka /kernel/trunk/ Printf ported back from uspace to kernel.
Printf calls changed to match new conventions.		  
1185 6595 d 1 h jermar /kernel/trunk/ Add task_create_arch() for all architectures.  
1178 6596 d 0 h jermar /kernel/trunk/ Add task_find_by_id().
Add kernel support for SYS_MAP_PHYSMEM.		  
1177 6596 d 4 h jermar /kernel/trunk/generic/ Modify B+tree node key width to be 64-bit wide on all platforms.  
1176 6596 d 4 h jermar /kernel/trunk/generic/ Kernel support for SYS_GET_TASK_ID syscall.  
1174 6596 d 6 h jermar /kernel/trunk/ Start capabilities support.  
1170 6597 d 0 h vana /kernel/trunk/ Stack size definition macro definition fix  
1168 6598 d 21 h vana /kernel/trunk/ Thread RSE support completion (kernel)  
1159 6599 d 1 h jermar /kernel/trunk/generic/ Replace list of all tasks with B+tree of all tasks.  
1115 6616 d 4 h jermar /kernel/trunk/generic/src/proc/ Fix kcpulb() to change state of the migrated thread to Entering so that thread_ready() won't panic() on violated assertion.
Make print out of threads and tasks more dense again.
