4055 6246 d 9 h trochtova /branches/dd/ changes in trunk (rev 4054) merged into dd branch  
3022 6529 d 11 h decky /branches/dd/ device drivers branch  
2504 6834 d 3 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 6892 d 6 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 6945 d 16 h decky /trunk/kernel/ start shutdown infrastructure  
2216 6947 d 2 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls
 
2106 7010 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 7014 d 9 h decky /trunk/kernel/ move ipc structures to ipc.h  
2103 7015 d 2 h decky /trunk/kernel/generic/include/ move timeout_t to timeout.h
move other helper types to thread.h
 
2096 7015 d 4 h decky /trunk/kernel/generic/include/ move thread_t to thread.h  
2093 7015 d 5 h decky /trunk/kernel/ spinlock extern declaration macro  
2092 7015 d 6 h decky /trunk/kernel/generic/include/ move cpu_t to cpu.h  
2090 7016 d 5 h decky /trunk/kernel/generic/include/proc/ cleanup garbage  
2089 7016 d 9 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2071 7027 d 1 h jermar /trunk/ (c) versus (C)  
2039 7061 d 9 h decky /trunk/kernel/generic/ accumulate task accounting, run tests as separate kernel task  
1888 7152 d 5 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.
 
1820 7199 d 23 h decky /trunk/kernel/generic/ initial security context support  
1787 7217 d 4 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 7224 d 5 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).
