4055 5657 d 4 h trochtova /branches/dd/ changes in trunk (rev 4054) merged into dd branch  
3022 5940 d 6 h decky /branches/dd/ device drivers branch  
2504 6244 d 22 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 6303 d 2 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 6356 d 11 h decky /trunk/kernel/ start shutdown infrastructure  
2216 6357 d 21 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls
 
2106 6421 d 4 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 6425 d 5 h decky /trunk/kernel/ move ipc structures to ipc.h  
2103 6425 d 21 h decky /trunk/kernel/generic/include/ move timeout_t to timeout.h
move other helper types to thread.h
 
2096 6425 d 23 h decky /trunk/kernel/generic/include/ move thread_t to thread.h  
2093 6426 d 0 h decky /trunk/kernel/ spinlock extern declaration macro  
2092 6426 d 1 h decky /trunk/kernel/generic/include/ move cpu_t to cpu.h  
2090 6427 d 0 h decky /trunk/kernel/generic/include/proc/ cleanup garbage  
2089 6427 d 4 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2071 6437 d 21 h jermar /trunk/ (c) versus (C)  
2039 6472 d 5 h decky /trunk/kernel/generic/ accumulate task accounting, run tests as separate kernel task  
1888 6563 d 0 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.
 
1820 6610 d 18 h decky /trunk/kernel/generic/ initial security context support  
1787 6627 d 23 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6635 d 0 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).
