2817 5945 d 4 h svoboda /branches/tracing/kernel/generic/ Add REGS_READ and REGS_WRITE debug methods to access userspace register state (no effect yet)  
2808 5946 d 3 h svoboda /branches/tracing/ add kernel answerbox+thread to mediate access to task's memory  
2805 5947 d 7 h svoboda /branches/tracing/ add ipc call to retrieve syscall arguments  
2804 5947 d 9 h svoboda /branches/tracing/kernel/generic/ allow for attaching to tasks with sleeping threads  
2801 5947 d 13 h svoboda /branches/tracing/ [tracing] initial debug interface support  
2799 5947 d 14 h svoboda /branches/tracing/ Revert all changes in tracing branch (sync to r2785 of trunk)  
2787 5956 d 7 h decky /branches/tracing/ add dynamic linking, debugging and tracing branch  
2746 5985 d 6 h decky /trunk/kernel/ start merging tasklets (more or less a rewrite)  
2504 6198 d 4 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.
 
2502 6198 d 9 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 6253 d 3 h jermar /trunk/kernel/generic/ JoinMe -> Lingering  
2446 6256 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 6257 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 6300 d 4 h jermar /trunk/kernel/generic/ Document and assert proper usage of THREAD_FLAG_WIRED.
Original patch by Jan Hudecek.
 
2227 6309 d 17 h decky /trunk/kernel/ start shutdown infrastructure  
2216 6311 d 3 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls
 
2187 6312 d 10 h decky /trunk/kernel/generic/ add syscall for getting current thread ID  
2109 6373 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 6374 d 10 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 6378 d 10 h decky /trunk/kernel/ move ipc structures to ipc.h  
2103 6379 d 3 h decky /trunk/kernel/generic/include/ move timeout_t to timeout.h
move other helper types to thread.h
 
2096 6379 d 5 h decky /trunk/kernel/generic/include/ move thread_t to thread.h  
2093 6379 d 6 h decky /trunk/kernel/ spinlock extern declaration macro  
2092 6379 d 7 h decky /trunk/kernel/generic/include/ move cpu_t to cpu.h  
2090 6380 d 6 h decky /trunk/kernel/generic/include/proc/ cleanup garbage  
2089 6380 d 9 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2081 6386 d 10 h decky /trunk/kernel/generic/include/ another typedefs to anonymous structs  
2080 6386 d 10 h decky /trunk/kernel/generic/include/ another typedef to anonymous enum  
2071 6391 d 2 h jermar /trunk/ (c) versus (C)  
2042 6425 d 6 h decky /trunk/kernel/ introduce uncounted threads, whose accounting doesn't affect accumulated task accounting
run tests in kconsole thread again
 
2039 6425 d 10 h decky /trunk/kernel/generic/ accumulate task accounting, run tests as separate kernel task  
2031 6426 d 11 h decky /trunk/kernel/generic/include/proc/ fix comment  
2030 6426 d 11 h decky /trunk/kernel/ thread CPU cycles accounting  
1888 6516 d 6 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.
 
1854 6532 d 12 h jermar /trunk/kernel/ Define architecture-specific thread sub-constructors and sub-destructors on all architectures.
Define the THREAD_FLAG_USPACE which means that the thread runs in user space.
The forementioned changes allow for allocating of user window buffer on sparc64
threads that execute in userspace.

A lot of formatting and indentation fixes.
 
1839 6556 d 7 h decky /trunk/kernel/generic/ finish security context isolation  
1820 6563 d 23 h decky /trunk/kernel/generic/ initial security context support  
1787 6581 d 4 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6588 d 6 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1702 6609 d 8 h cejka /kernel/trunk/ Kernel doxygen comments updated.
