2902 5914 d 10 h svoboda /branches/tracing/kernel/generic/ Implement proper kbox thread shutdown, with all bells and whistles. Use THREAD->debug_active in udebug_stoppable_xx() and friends  
2899 5914 d 23 h svoboda /branches/tracing/ Add support for SET_EVMASK debug operation  
2898 5915 d 0 h svoboda /branches/tracing/ Implement operation UDEBUG_M_STOP that stops a thread. Can be used for stopping program by hitting a key in debugger. Somewhat jittery demo in sctrace. Fix missing lock of THREAD->debug_lock in udebug_stoppable_end()  
2870 5923 d 21 h svoboda /branches/tracing/kernel/generic/ Terminate debugging session on debugger disconnect  
2866 5924 d 8 h svoboda /branches/tracing/kernel/generic/ Verify that thread is waiting in syscall event when reading syscall args  
2848 5943 d 7 h svoboda /branches/tracing/kernel/generic/ Use debug_lock in thread struct for finer locking, to avoid problems with waitq_wakeup  
2839 5944 d 1 h svoboda /branches/tracing/kernel/generic/ Add thread_attach_by_id() and use it to do ipc_connect_kbox() with proper locking  
2827 5948 d 8 h svoboda /branches/tracing/kernel/generic/ Verify that a thread/task is in appropriate state when handling debug calls  
2826 5948 d 9 h svoboda /branches/tracing/kernel/generic/ Move debug_go_call from task struct to thread struct  
2825 5948 d 9 h svoboda /branches/tracing/kernel/generic/ Introduce task debug-states (udebug_task_state_t)  
2817 5949 d 0 h svoboda /branches/tracing/kernel/generic/ Add REGS_READ and REGS_WRITE debug methods to access userspace register state (no effect yet)  
2808 5949 d 23 h svoboda /branches/tracing/ add kernel answerbox+thread to mediate access to task's memory  
2805 5951 d 3 h svoboda /branches/tracing/ add ipc call to retrieve syscall arguments  
2804 5951 d 5 h svoboda /branches/tracing/kernel/generic/ allow for attaching to tasks with sleeping threads  
2801 5951 d 10 h svoboda /branches/tracing/ [tracing] initial debug interface support  
2799 5951 d 11 h svoboda /branches/tracing/ Revert all changes in tracing branch (sync to r2785 of trunk)  
2787 5960 d 3 h decky /branches/tracing/ add dynamic linking, debugging and tracing branch  
2746 5989 d 2 h decky /trunk/kernel/ start merging tasklets (more or less a rewrite)  
2504 6202 d 0 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 6202 d 5 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 6256 d 23 h jermar /trunk/kernel/generic/ JoinMe -> Lingering  
2446 6260 d 3 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 6260 d 22 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 6304 d 0 h jermar /trunk/kernel/generic/ Document and assert proper usage of THREAD_FLAG_WIRED.
Original patch by Jan Hudecek.
 
2227 6313 d 13 h decky /trunk/kernel/ start shutdown infrastructure  
2216 6314 d 23 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls
 
2187 6316 d 6 h decky /trunk/kernel/generic/ add syscall for getting current thread ID  
2109 6377 d 7 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 6378 d 6 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 6382 d 6 h decky /trunk/kernel/ move ipc structures to ipc.h

2089 6384 d 6 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2081 6390 d 6 h decky /trunk/kernel/generic/include/ another typedefs to anonymous structs
