2040 6458 d 5 h decky /trunk/kernel/generic/src/proc/ add forgotten btree_remove()  
2039 6458 d 6 h decky /trunk/kernel/generic/ accumulate task accounting, run tests as separate kernel task  
2035 6459 d 4 h decky /trunk/kernel/generic/src/ more fancy kconsole output  
2000 6474 d 8 h decky /trunk/kernel/ move files to more proper locations  
1880 6552 d 22 h jermar /trunk/ Small improvements here and there.  
1864 6559 d 19 h jermar /trunk/ sparc64 update.
- Prototype userspace layer implementation that
at least relates to sparc64 and compiles cleanly.
- Fixes for kernel's preemptible_handler and code
related to running userspace.
- Enable userspace. Several dozen instructions
are now run in userspace! We are pretty near
the userspace milestone for sparc64.		  
1839 6589 d 3 h decky /trunk/kernel/generic/ finish security context isolation  
1820 6596 d 20 h decky /trunk/kernel/generic/ initial security context support  
1787 6614 d 1 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6621 d 2 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1757 6635 d 7 h jermar /kernel/trunk/ Cleanup of comments.  
1735 6637 d 8 h decky /kernel/trunk/ make kernel prints case consistent  
1702 6642 d 5 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1687 6645 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 6645 d 9 h jermar /kernel/trunk/ #ifdef more debugging printf()'s.  
1676 6646 d 5 h jermar /kernel/trunk/generic/src/proc/ Forgotten interrupts_restore().  
1661 6647 d 10 h jermar /kernel/trunk/generic/ Collect Undead threads while waiting to join uinit.
Rename ktaskkill to ktaskgc.		  
1636 6648 d 18 h jermar /kernel/trunk/ Move comment.

Do TLB shootdown also when allocating new ASID.		  
1600 6649 d 10 h jermar /kernel/trunk/generic/src/proc/ Prevent task killing of kernel by returning EPERM on such a request.  
1597 6649 d 11 h palkovsky /kernel/trunk/ Added possibility to interrupt task at exit from interrupt routine.  
1589 6650 d 0 h jermar /kernel/trunk/generic/src/ Improve comments regarding liveliness of threads and tasks.  
1588 6650 d 1 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 6650 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 6650 d 5 h jermar /kernel/trunk/generic/ Kill task when its main thread exits.  
1583 6650 d 8 h jermar /kernel/trunk/generic/ Make ktaskclnp call ipc_cleanup and futex_cleanup.  
1580 6650 d 11 h jermar /kernel/trunk/generic/src/ Update for task_kill().  
1579 6650 d 21 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 6651 d 2 h palkovsky /kernel/trunk/generic/ Renamed some things in IPC to be consistent.
Added ipc reporting to kconsole.		  
1468 6655 d 3 h jermar /kernel/trunk/ Function for destroying address space for which there is no other reference in the kernel.  
1460 6655 d 6 h jermar /kernel/trunk/generic/ Reference counting for futexes.  
1424 6659 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 6662 d 20 h jermar /kernel/trunk/generic/ Some shared memory stuff (not completed).
Support for address space area backends.
Add ELF and anonymous memory backends.		  
1358 6670 d 2 h jermar /kernel/trunk/generic/ Cleanup after removal of as_area_accept and as_area_send.  
1288 6681 d 7 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 6689 d 2 h jermar /kernel/trunk/ Add some @file doxygen comments and improve already existing comments.  
1239 6690 d 1 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 6690 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 6692 d 6 h jermar /kernel/trunk/ Remove the outdated TODO file.
Improve doxygen comments here and there.		  
1227 6693 d 3 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 6700 d 6 h cejka /kernel/trunk/ Printf ported back from uspace to kernel.
Printf calls changed to match new conventions.
