4055 6147 d 0 h trochtova /branches/dd/ changes in trunk (rev 4054) merged into dd branch  
3022 6430 d 2 h decky /branches/dd/ device drivers branch  
2504 6734 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.
 
2446 6792 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.
 
2227 6846 d 7 h decky /trunk/kernel/ start shutdown infrastructure  
2216 6847 d 17 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls
 
2106 6911 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 6915 d 0 h decky /trunk/kernel/ move ipc structures to ipc.h  
2103 6915 d 17 h decky /trunk/kernel/generic/include/ move timeout_t to timeout.h
move other helper types to thread.h
 
2096 6915 d 19 h decky /trunk/kernel/generic/include/ move thread_t to thread.h  
2093 6915 d 20 h decky /trunk/kernel/ spinlock extern declaration macro  
2092 6915 d 21 h decky /trunk/kernel/generic/include/ move cpu_t to cpu.h  
2090 6916 d 20 h decky /trunk/kernel/generic/include/proc/ cleanup garbage  
2089 6917 d 0 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2071 6927 d 17 h jermar /trunk/ (c) versus (C)  
2039 6962 d 1 h decky /trunk/kernel/generic/ accumulate task accounting, run tests as separate kernel task  
1888 7052 d 20 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.
 
1820 7100 d 14 h decky /trunk/kernel/generic/ initial security context support  
1787 7117 d 19 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 7124 d 20 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).
