3035 5906 d 5 h svoboda /branches/tracing/kernel/generic/ Use thread_join() to wait for kbox thread termination, instead of specific wait queue.  
3034 5906 d 7 h svoboda /branches/tracing/kernel/generic/ Convert kb_cleanup_lock to a mutex  
3014 5909 d 8 h svoboda /branches/tracing/kernel/generic/ Isolate udebug-related task_t fields into udebug_task_t.  
2902 5925 d 8 h svoboda /branches/tracing/kernel/generic/ Implement proper kbox thread shutdown, with all bells and whistles. Use THREAD->debug_active in udebug_stoppable_xx() and friends  
2899 5925 d 21 h svoboda /branches/tracing/ Add support for SET_EVMASK debug operation  
2870 5934 d 19 h svoboda /branches/tracing/kernel/generic/ Terminate debugging session on debugger disconnect  
2839 5954 d 23 h svoboda /branches/tracing/kernel/generic/ Add thread_attach_by_id() and use it to do ipc_connect_kbox() with proper locking  
2826 5959 d 7 h svoboda /branches/tracing/kernel/generic/ Move debug_go_call from task struct to thread struct  
2825 5959 d 7 h svoboda /branches/tracing/kernel/generic/ Introduce task debug-states (udebug_task_state_t)  
2808 5960 d 21 h svoboda /branches/tracing/ add kernel answerbox+thread to mediate access to task's memory  
2804 5962 d 3 h svoboda /branches/tracing/kernel/generic/ allow for attaching to tasks with sleeping threads  
2801 5962 d 8 h svoboda /branches/tracing/ [tracing] initial debug interface support  
2799 5962 d 9 h svoboda /branches/tracing/ Revert all changes in tracing branch (sync to r2785 of trunk)  
2787 5971 d 1 h decky /branches/tracing/ add dynamic linking, debugging and tracing branch  
2504 6212 d 22 h jermar /trunk/kernel/generic/ Give the AVL tree walkers the possibility to take an argument.
Each walker is now supposed to return a bool value to support walk termination.

Switch over from the tasks_btree B+tree to tasks_tree AVL tree.
This makes the fix for ticket #48 complete.
 
2446 6271 d 1 h jermar /trunk/kernel/generic/ More efficient and simpler task termination.

Based on the assumption, that after its creation, only the task itself can create more threads for itself,
the last thread with userspace context to execute thread_exit() will perform futex and IPC cleanup. When
the task has no threads, it is destroyed. Both the cleanup and destruction is controlled by reference
counting.

As for userspace threads, even though there could be a global garbage collector for joining threads, it is
much simpler if the uinit thread detaches itself before switching to userspace.

task_kill() is now an idempotent operation. It just instructs the threads within a task to exit.

Change in the name of a thread state: Undead -> JoinMe.
 
2227 6324 d 11 h decky /trunk/kernel/ start shutdown infrastructure  
2216 6325 d 21 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls
 
2106 6389 d 4 h jermar /trunk/kernel/ Merge as_t structure into one and leave the differring parts in as_genarch_t.

Indentation and formatting changes in header files.
 
2105 6393 d 4 h decky /trunk/kernel/ move ipc structures to ipc.h  
2103 6393 d 21 h decky /trunk/kernel/generic/include/ move timeout_t to timeout.h
move other helper types to thread.h
 
2096 6393 d 23 h decky /trunk/kernel/generic/include/ move thread_t to thread.h  
2093 6394 d 0 h decky /trunk/kernel/ spinlock extern declaration macro  
2092 6394 d 1 h decky /trunk/kernel/generic/include/ move cpu_t to cpu.h  
2090 6395 d 0 h decky /trunk/kernel/generic/include/proc/ cleanup garbage  
2089 6395 d 4 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2071 6405 d 21 h jermar /trunk/ (c) versus (C)  
2039 6440 d 5 h decky /trunk/kernel/generic/ accumulate task accounting, run tests as separate kernel task  
1888 6531 d 0 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.
 
1820 6578 d 18 h decky /trunk/kernel/generic/ initial security context support  
1787 6595 d 23 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6603 d 0 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1702 6624 d 3 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1587 6632 d 0 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 6632 d 3 h jermar /kernel/trunk/generic/ Kill task when its main thread exits.  
1583 6632 d 6 h jermar /kernel/trunk/generic/ Make ktaskclnp call ipc_cleanup and futex_cleanup.  
1579 6632 d 19 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.
 
1568 6633 d 1 h palkovsky /kernel/trunk/generic/ Slightly remodelled ipc hangups to facilitate correct cleanup.
