2041 6424 d 16 h decky /trunk/kernel/generic/src/proc/ revert 2040  
2040 6424 d 18 h decky /trunk/kernel/generic/src/proc/ add forgotten btree_remove()  
2039 6424 d 19 h decky /trunk/kernel/generic/ accumulate task accounting, run tests as separate kernel task  
2035 6425 d 17 h decky /trunk/kernel/generic/src/ more fancy kconsole output  
2000 6440 d 20 h decky /trunk/kernel/ move files to more proper locations  
1880 6519 d 10 h jermar /trunk/ Small improvements here and there.  
1864 6526 d 8 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 6555 d 15 h decky /trunk/kernel/generic/ finish security context isolation  
1820 6563 d 8 h decky /trunk/kernel/generic/ initial security context support  
1787 6580 d 13 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6587 d 14 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1757 6601 d 19 h jermar /kernel/trunk/ Cleanup of comments.  
1735 6603 d 21 h decky /kernel/trunk/ make kernel prints case consistent  
1702 6608 d 17 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1687 6611 d 18 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 6611 d 21 h jermar /kernel/trunk/ #ifdef more debugging printf()'s.  
1676 6612 d 18 h jermar /kernel/trunk/generic/src/proc/ Forgotten interrupts_restore().  
1661 6613 d 22 h jermar /kernel/trunk/generic/ Collect Undead threads while waiting to join uinit.
Rename ktaskkill to ktaskgc.
 
1636 6615 d 7 h jermar /kernel/trunk/ Move comment.

Do TLB shootdown also when allocating new ASID.
 
1600 6615 d 23 h jermar /kernel/trunk/generic/src/proc/ Prevent task killing of kernel by returning EPERM on such a request.  
1597 6615 d 23 h palkovsky /kernel/trunk/ Added possibility to interrupt task at exit from interrupt routine.  
1589 6616 d 13 h jermar /kernel/trunk/generic/src/ Improve comments regarding liveliness of threads and tasks.  
1588 6616 d 13 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 6616 d 14 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 6616 d 17 h jermar /kernel/trunk/generic/ Kill task when its main thread exits.  
1583 6616 d 20 h jermar /kernel/trunk/generic/ Make ktaskclnp call ipc_cleanup and futex_cleanup.  
1580 6617 d 0 h jermar /kernel/trunk/generic/src/ Update for task_kill().  
1579 6617 d 10 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 6617 d 14 h palkovsky /kernel/trunk/generic/ Renamed some things in IPC to be consistent.
Added ipc reporting to kconsole.
 
1468 6621 d 15 h jermar /kernel/trunk/ Function for destroying address space for which there is no other reference in the kernel.  
1460 6621 d 19 h jermar /kernel/trunk/generic/ Reference counting for futexes.  
1424 6625 d 14 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 6629 d 8 h jermar /kernel/trunk/generic/ Some shared memory stuff (not completed).
Support for address space area backends.
Add ELF and anonymous memory backends.
 
1358 6636 d 14 h jermar /kernel/trunk/generic/ Cleanup after removal of as_area_accept and as_area_send.  
1288 6647 d 20 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 6655 d 14 h jermar /kernel/trunk/ Add some @file doxygen comments and improve already existing comments.  
1239 6656 d 14 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 6656 d 20 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 6658 d 19 h jermar /kernel/trunk/ Remove the outdated TODO file.
Improve doxygen comments here and there.
 
1227 6659 d 15 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.
