3597 5833 d 10 h svoboda /branches/tracing/ Merge latest trunk changes into tracing.  
3431 5898 d 11 h svoboda /branches/tracing/kernel/ Add configuration option CONFIG_UDEBUG to compile udebug in the kernel or not.  
3425 5898 d 23 h svoboda /branches/tracing/ Merge latest trunk changes into tracing (broken)  
3424 5899 d 10 h svoboda /branches/tracing/ Merge trunk changes up to r3180 into tracing  
3034 6006 d 22 h svoboda /branches/tracing/kernel/generic/ Convert kb_cleanup_lock to a mutex  
3018 6009 d 15 h svoboda /branches/tracing/ Isolate udebug-related thread_t fields into udebug_thread_t  
3015 6009 d 21 h svoboda /branches/tracing/kernel/generic/ Call udebug_stoppable_begin() after scheduling, rather than before - avoid restricted contex.  
2902 6025 d 23 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  
2898 6026 d 13 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()  
2866 6035 d 22 h svoboda /branches/tracing/kernel/generic/ Verify that thread is waiting in syscall event when reading syscall args  
2848 6054 d 21 h svoboda /branches/tracing/kernel/generic/ Use debug_lock in thread struct for finer locking, to avoid problems with waitq_wakeup  
2839 6055 d 14 h svoboda /branches/tracing/kernel/generic/ Add thread_attach_by_id() and use it to do ipc_connect_kbox() with proper locking  
2827 6059 d 21 h svoboda /branches/tracing/kernel/generic/ Verify that a thread/task is in appropriate state when handling debug calls  
2826 6059 d 22 h svoboda /branches/tracing/kernel/generic/ Move debug_go_call from task struct to thread struct  
2825 6059 d 22 h svoboda /branches/tracing/kernel/generic/ Introduce task debug-states (udebug_task_state_t)  
2817 6060 d 14 h svoboda /branches/tracing/kernel/generic/ Add REGS_READ and REGS_WRITE debug methods to access userspace register state (no effect yet)  
2805 6062 d 17 h svoboda /branches/tracing/ add ipc call to retrieve syscall arguments  
2801 6062 d 23 h svoboda /branches/tracing/ [tracing] initial debug interface support  
2799 6063 d 0 h svoboda /branches/tracing/ Revert all changes in tracing branch (sync to r2785 of trunk)  
2787 6071 d 16 h decky /branches/tracing/ add dynamic linking, debugging and tracing branch  
2502 6313 d 19 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 6368 d 12 h jermar /trunk/kernel/generic/ JoinMe -> Lingering  
2446 6371 d 17 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 6372 d 11 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 6415 d 13 h jermar /trunk/kernel/generic/ Document and assert proper usage of THREAD_FLAG_WIRED.
Original patch by Jan Hudecek.
 
2216 6426 d 12 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls
 
2187 6427 d 19 h decky /trunk/kernel/generic/ add syscall for getting current thread ID  
2109 6488 d 21 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 6489 d 19 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.
 
2103 6494 d 12 h decky /trunk/kernel/generic/include/ move timeout_t to timeout.h
move other helper types to thread.h
 
2096 6494 d 14 h decky /trunk/kernel/generic/include/ move thread_t to thread.h  
2093 6494 d 15 h decky /trunk/kernel/ spinlock extern declaration macro  
2089 6495 d 19 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2080 6501 d 20 h decky /trunk/kernel/generic/include/ another typedef to anonymous enum  
2071 6506 d 12 h jermar /trunk/ (c) versus (C)  
2042 6540 d 16 h decky /trunk/kernel/ introduce uncounted threads, whose accounting doesn't affect accumulated task accounting
run tests in kconsole thread again
 
2031 6541 d 20 h decky /trunk/kernel/generic/include/proc/ fix comment  
2030 6541 d 20 h decky /trunk/kernel/ thread CPU cycles accounting  
1888 6631 d 15 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.
 
1854 6647 d 21 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.
