3597 5695 d 22 h svoboda /branches/tracing/ Merge latest trunk changes into tracing.  
3431 5760 d 23 h svoboda /branches/tracing/kernel/ Add configuration option CONFIG_UDEBUG to compile udebug in the kernel or not.  
3425 5761 d 11 h svoboda /branches/tracing/ Merge latest trunk changes into tracing (broken)  
3424 5761 d 22 h svoboda /branches/tracing/ Merge trunk changes up to r3180 into tracing  
3035 5869 d 8 h svoboda /branches/tracing/kernel/generic/ Use thread_join() to wait for kbox thread termination, instead of specific wait queue.  
3034 5869 d 10 h svoboda /branches/tracing/kernel/generic/ Convert kb_cleanup_lock to a mutex  
3014 5872 d 11 h svoboda /branches/tracing/kernel/generic/ Isolate udebug-related task_t fields into udebug_task_t.  
2902 5888 d 11 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 5889 d 0 h svoboda /branches/tracing/ Add support for SET_EVMASK debug operation  
2870 5897 d 23 h svoboda /branches/tracing/kernel/generic/ Terminate debugging session on debugger disconnect  
2839 5918 d 2 h svoboda /branches/tracing/kernel/generic/ Add thread_attach_by_id() and use it to do ipc_connect_kbox() with proper locking  
2826 5922 d 10 h svoboda /branches/tracing/kernel/generic/ Move debug_go_call from task struct to thread struct  
2825 5922 d 11 h svoboda /branches/tracing/kernel/generic/ Introduce task debug-states (udebug_task_state_t)  
2808 5924 d 0 h svoboda /branches/tracing/ add kernel answerbox+thread to mediate access to task's memory  
2804 5925 d 6 h svoboda /branches/tracing/kernel/generic/ allow for attaching to tasks with sleeping threads  
2801 5925 d 11 h svoboda /branches/tracing/ [tracing] initial debug interface support  
2799 5925 d 12 h svoboda /branches/tracing/ Revert all changes in tracing branch (sync to r2785 of trunk)  
2787 5934 d 4 h decky /branches/tracing/ add dynamic linking, debugging and tracing branch  
2504 6176 d 1 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 6234 d 5 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 6287 d 14 h decky /trunk/kernel/ start shutdown infrastructure  
2216 6289 d 0 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls
 
2106 6352 d 7 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 6356 d 8 h decky /trunk/kernel/ move ipc structures to ipc.h  
2103 6357 d 0 h decky /trunk/kernel/generic/include/ move timeout_t to timeout.h
move other helper types to thread.h
 
2096 6357 d 2 h decky /trunk/kernel/generic/include/ move thread_t to thread.h  
2093 6357 d 3 h decky /trunk/kernel/ spinlock extern declaration macro  
2092 6357 d 4 h decky /trunk/kernel/generic/include/ move cpu_t to cpu.h  
2090 6358 d 3 h decky /trunk/kernel/generic/include/proc/ cleanup garbage  
2089 6358 d 7 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2071 6369 d 0 h jermar /trunk/ (c) versus (C)  
2039 6403 d 8 h decky /trunk/kernel/generic/ accumulate task accounting, run tests as separate kernel task  
1888 6494 d 3 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.
 
1820 6541 d 21 h decky /trunk/kernel/generic/ initial security context support  
1787 6559 d 2 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6566 d 3 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1702 6587 d 6 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1587 6595 d 3 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 6595 d 6 h jermar /kernel/trunk/generic/ Kill task when its main thread exits.  
1583 6595 d 9 h jermar /kernel/trunk/generic/ Make ktaskclnp call ipc_cleanup and futex_cleanup.
