3566 5713 d 11 h svoboda /trunk/ Set meaningful names for loaded programs. Now 'tasks' kconsole command is much less obscure.  
3565 5713 d 21 h svoboda /trunk/ Fix sys_thread_create(): could fail when passed name was at end of mapping, could crash if provided name was not null-terminated.  
3438 5765 d 8 h svoboda /trunk/ Merge syscall tracer (trace) and relevant part of udebug interface from tracing to trunk.  
3222 5836 d 5 h svoboda /trunk/ Merge program-loader related stuff from dynload branch to trunk. (huge)  
3068 5871 d 6 h decky /trunk/kernel/generic/include/ reflect changes in sources  
2926 5890 d 11 h decky /trunk/kernel/generic/include/proc/ cs change  
2746 5968 d 4 h decky /trunk/kernel/ start merging tasklets (more or less a rewrite)  
2504 6181 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.
 
2502 6181 d 7 h jermar /trunk/kernel/generic/ Replace the threads_btree B+tree with an AVL tree. The new variable is called
threads_tree. For printing list of threads, use the new AVL tree walker
mechanism.

This solves half of ticket #48.
 
2451 6236 d 1 h jermar /trunk/kernel/generic/ JoinMe -> Lingering  
2446 6239 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.
 
2440 6239 d 23 h jermar /trunk/kernel/generic/ Fix the problem with sys_thread_create() by splitting the create and attach functionality of
thread_create(). Now it is possible to specify a flag that will cause thread_create() to only allocate and
initialize the thread structure. A call to thread_attach() will make the thread visible to the system.
This arrangement makes it easier to undo creation of a thread in case of a failure in sys_thread_create().
 
2268 6283 d 1 h jermar /trunk/kernel/generic/ Document and assert proper usage of THREAD_FLAG_WIRED.
Original patch by Jan Hudecek.
 
2227 6292 d 14 h decky /trunk/kernel/ start shutdown infrastructure  
2216 6294 d 0 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls
 
2187 6295 d 8 h decky /trunk/kernel/generic/ add syscall for getting current thread ID  
2109 6356 d 9 h jermar /trunk/kernel/generic/ Revert thread_interrupt_sleep() to waitq_interrupt_sleep().
I'd prefer that this, IMO, waitq related stuff stays together.
 
2106 6357 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 6361 d 8 h decky /trunk/kernel/ move ipc structures to ipc.h  
2103 6362 d 1 h decky /trunk/kernel/generic/include/ move timeout_t to timeout.h
move other helper types to thread.h
 
2096 6362 d 3 h decky /trunk/kernel/generic/include/ move thread_t to thread.h  
2093 6362 d 3 h decky /trunk/kernel/ spinlock extern declaration macro  
2092 6362 d 4 h decky /trunk/kernel/generic/include/ move cpu_t to cpu.h  
2090 6363 d 3 h decky /trunk/kernel/generic/include/proc/ cleanup garbage  
2089 6363 d 7 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2081 6369 d 8 h decky /trunk/kernel/generic/include/ another typedefs to anonymous structs  
2080 6369 d 8 h decky /trunk/kernel/generic/include/ another typedef to anonymous enum  
2071 6374 d 0 h jermar /trunk/ (c) versus (C)  
2042 6408 d 4 h decky /trunk/kernel/ introduce uncounted threads, whose accounting doesn't affect accumulated task accounting
run tests in kconsole thread again
 
2039 6408 d 8 h decky /trunk/kernel/generic/ accumulate task accounting, run tests as separate kernel task  
2031 6409 d 8 h decky /trunk/kernel/generic/include/proc/ fix comment  
2030 6409 d 8 h decky /trunk/kernel/ thread CPU cycles accounting  
1888 6499 d 3 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.
 
1854 6515 d 9 h jermar /trunk/kernel/ Define architecture-specific thread sub-constructors and sub-destructors on all architectures.
Define the THREAD_FLAG_USPACE which means that the thread runs in user space.
The forementioned changes allow for allocating of user window buffer on sparc64
threads that execute in userspace.

A lot of formatting and indentation fixes.
 
1839 6539 d 5 h decky /trunk/kernel/generic/ finish security context isolation  
1820 6546 d 21 h decky /trunk/kernel/generic/ initial security context support  
1787 6564 d 2 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6571 d 3 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1702 6592 d 6 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1661 6597 d 12 h jermar /kernel/trunk/generic/ Collect Undead threads while waiting to join uinit.
Rename ktaskkill to ktaskgc.
