3569 5844 d 16 h svoboda /branches/dynload/ Merge latest trunk changes into dynload.  
3448 5895 d 18 h svoboda /branches/dynload/ Merge latest trunk changes into dynload  
3190 5975 d 14 h svoboda /branches/dynload/ Remove vestiges of loading code coming from trunk  
3149 5989 d 14 h svoboda /branches/dynload/ Merge trunk changes up to r3071 into dynload (broken)  
2927 6021 d 17 h decky /branches/dynload/ added dynload branch  
2502 6312 d 13 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 6367 d 7 h jermar /trunk/kernel/generic/ JoinMe -> Lingering  
2446 6370 d 11 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 6371 d 6 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 6414 d 8 h jermar /trunk/kernel/generic/ Document and assert proper usage of THREAD_FLAG_WIRED.
Original patch by Jan Hudecek.		  
2216 6425 d 7 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls		  
2187 6426 d 14 h decky /trunk/kernel/generic/ add syscall for getting current thread ID  
2109 6487 d 16 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 6488 d 14 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.		  
2103 6493 d 7 h decky /trunk/kernel/generic/include/ move timeout_t to timeout.h
move other helper types to thread.h		  
2096 6493 d 9 h decky /trunk/kernel/generic/include/ move thread_t to thread.h  
2093 6493 d 10 h decky /trunk/kernel/ spinlock extern declaration macro  
2089 6494 d 14 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2080 6500 d 15 h decky /trunk/kernel/generic/include/ another typedef to anonymous enum  
2071 6505 d 7 h jermar /trunk/ (c) versus (C)
