4691 5544 d 18 h svoboda /branches/dynload/ Merge trunk changes up to r4686.  
4344 5656 d 16 h svoboda /branches/dynload/ Merge trunk changes up to r3988 to dynload.  
4343 5656 d 16 h svoboda /branches/dynload/ Merged trunk changes up to r3925 to dynload.  
3674 5801 d 15 h svoboda /branches/dynload/ Merge latest trunk changes to dynload.  
3569 5829 d 2 h svoboda /branches/dynload/ Merge latest trunk changes into dynload.  
3448 5880 d 4 h svoboda /branches/dynload/ Merge latest trunk changes into dynload  
3203 5954 d 1 h svoboda /branches/dynload/ Move stuff related to running programs to a separate source file proc/program.c  
3190 5960 d 0 h svoboda /branches/dynload/ Remove vestiges of loading code coming from trunk  
3149 5974 d 0 h svoboda /branches/dynload/ Merge trunk changes up to r3071 into dynload (broken)  
3004 5994 d 22 h svoboda /branches/dynload/ A crude task_spawn() libc function to run a program. A tiny command-line application 'cli' to test it.  
3001 5995 d 22 h svoboda /branches/dynload/kernel/generic/ Kernel support for running programs from userspace.  
2927 6006 d 3 h decky /branches/dynload/ added dynload branch  
2746 6083 d 20 h decky /trunk/kernel/ start merging tasklets (more or less a rewrite)  
2504 6296 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.
 
2502 6296 d 23 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 6351 d 17 h jermar /trunk/kernel/generic/ JoinMe -> Lingering  
2446 6354 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.
 
2440 6355 d 16 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 6398 d 18 h jermar /trunk/kernel/generic/ Document and assert proper usage of THREAD_FLAG_WIRED.
Original patch by Jan Hudecek.
 
2227 6408 d 7 h decky /trunk/kernel/ start shutdown infrastructure  
2216 6409 d 17 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls
 
2187 6411 d 0 h decky /trunk/kernel/generic/ add syscall for getting current thread ID  
2109 6472 d 1 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 6473 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 6477 d 0 h decky /trunk/kernel/ move ipc structures to ipc.h  
2103 6477 d 17 h decky /trunk/kernel/generic/include/ move timeout_t to timeout.h
move other helper types to thread.h
 
2096 6477 d 19 h decky /trunk/kernel/generic/include/ move thread_t to thread.h  
2093 6477 d 20 h decky /trunk/kernel/ spinlock extern declaration macro  
2092 6477 d 21 h decky /trunk/kernel/generic/include/ move cpu_t to cpu.h  
2090 6478 d 20 h decky /trunk/kernel/generic/include/proc/ cleanup garbage  
2089 6479 d 0 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2081 6485 d 0 h decky /trunk/kernel/generic/include/ another typedefs to anonymous structs  
2080 6485 d 0 h decky /trunk/kernel/generic/include/ another typedef to anonymous enum  
2071 6489 d 17 h jermar /trunk/ (c) versus (C)  
2042 6523 d 20 h decky /trunk/kernel/ introduce uncounted threads, whose accounting doesn't affect accumulated task accounting
run tests in kconsole thread again
 
2039 6524 d 0 h decky /trunk/kernel/generic/ accumulate task accounting, run tests as separate kernel task  
2031 6525 d 1 h decky /trunk/kernel/generic/include/proc/ fix comment  
2030 6525 d 1 h decky /trunk/kernel/ thread CPU cycles accounting  
1888 6614 d 20 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.
 
1854 6631 d 2 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.
