2474 6274 d 1 h jermar /tags/0.2.0.5/ Add tag for HelenOS 0.2.0.5.  
2451 6288 d 3 h jermar /trunk/kernel/generic/ JoinMe -> Lingering  
2446 6291 d 7 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 6292 d 1 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 6335 d 4 h jermar /trunk/kernel/generic/ Document and assert proper usage of THREAD_FLAG_WIRED.
Original patch by Jan Hudecek.		  
2227 6344 d 16 h decky /trunk/kernel/ start shutdown infrastructure  
2216 6346 d 3 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls		  
2187 6347 d 10 h decky /trunk/kernel/generic/ add syscall for getting current thread ID  
2109 6408 d 11 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 6409 d 9 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 6413 d 10 h decky /trunk/kernel/ move ipc structures to ipc.h  
2103 6414 d 3 h decky /trunk/kernel/generic/include/ move timeout_t to timeout.h
move other helper types to thread.h		  
2096 6414 d 5 h decky /trunk/kernel/generic/include/ move thread_t to thread.h  
2093 6414 d 5 h decky /trunk/kernel/ spinlock extern declaration macro  
2092 6414 d 6 h decky /trunk/kernel/generic/include/ move cpu_t to cpu.h  
2090 6415 d 5 h decky /trunk/kernel/generic/include/proc/ cleanup garbage  
2089 6415 d 9 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2081 6421 d 10 h decky /trunk/kernel/generic/include/ another typedefs to anonymous structs  
2080 6421 d 10 h decky /trunk/kernel/generic/include/ another typedef to anonymous enum  
2071 6426 d 2 h jermar /trunk/ (c) versus (C)
