4377 5628 d 17 h svoboda /branches/tracing/ Merge latest trunk changes to tracing. (i.e. revs 3684:4374, huge). This time hopefully the real thing.  
3623 5798 d 2 h svoboda /branches/tracing/ Merge latest trunk changes into tracing.  
3597 5800 d 15 h svoboda /branches/tracing/ Merge latest trunk changes into tracing.  
3431 5865 d 16 h svoboda /branches/tracing/kernel/ Add configuration option CONFIG_UDEBUG to compile udebug in the kernel or not.  
3425 5866 d 4 h svoboda /branches/tracing/ Merge latest trunk changes into tracing (broken)  
3424 5866 d 15 h svoboda /branches/tracing/ Merge trunk changes up to r3180 into tracing  
3035 5974 d 1 h svoboda /branches/tracing/kernel/generic/ Use thread_join() to wait for kbox thread termination, instead of specific wait queue.  
3034 5974 d 3 h svoboda /branches/tracing/kernel/generic/ Convert kb_cleanup_lock to a mutex  
3014 5977 d 4 h svoboda /branches/tracing/kernel/generic/ Isolate udebug-related task_t fields into udebug_task_t.  
2902 5993 d 4 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 5993 d 16 h svoboda /branches/tracing/ Add support for SET_EVMASK debug operation  
2870 6002 d 15 h svoboda /branches/tracing/kernel/generic/ Terminate debugging session on debugger disconnect  
2839 6022 d 19 h svoboda /branches/tracing/kernel/generic/ Add thread_attach_by_id() and use it to do ipc_connect_kbox() with proper locking  
2826 6027 d 3 h svoboda /branches/tracing/kernel/generic/ Move debug_go_call from task struct to thread struct  
2825 6027 d 3 h svoboda /branches/tracing/kernel/generic/ Introduce task debug-states (udebug_task_state_t)  
2808 6028 d 17 h svoboda /branches/tracing/ add kernel answerbox+thread to mediate access to task's memory  
2804 6029 d 23 h svoboda /branches/tracing/kernel/generic/ allow for attaching to tasks with sleeping threads  
2801 6030 d 3 h svoboda /branches/tracing/ [tracing] initial debug interface support  
2799 6030 d 5 h svoboda /branches/tracing/ Revert all changes in tracing branch (sync to r2785 of trunk)  
2787 6038 d 21 h decky /branches/tracing/ add dynamic linking, debugging and tracing branch  
2504 6280 d 18 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 6338 d 21 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 6392 d 7 h decky /trunk/kernel/ start shutdown infrastructure  
2216 6393 d 17 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls
 
2106 6457 d 0 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 6461 d 0 h decky /trunk/kernel/ move ipc structures to ipc.h  
2103 6461 d 17 h decky /trunk/kernel/generic/include/ move timeout_t to timeout.h
move other helper types to thread.h
 
2096 6461 d 19 h decky /trunk/kernel/generic/include/ move thread_t to thread.h  
2093 6461 d 20 h decky /trunk/kernel/ spinlock extern declaration macro  
2092 6461 d 21 h decky /trunk/kernel/generic/include/ move cpu_t to cpu.h  
2090 6462 d 20 h decky /trunk/kernel/generic/include/proc/ cleanup garbage  
2089 6463 d 0 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2071 6473 d 17 h jermar /trunk/ (c) versus (C)  
2039 6508 d 1 h decky /trunk/kernel/generic/ accumulate task accounting, run tests as separate kernel task  
1888 6598 d 20 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.
 
1820 6646 d 14 h decky /trunk/kernel/generic/ initial security context support  
1787 6663 d 19 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6670 d 20 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1702 6691 d 23 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1587 6699 d 20 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.
