3034 5912 d 1 h svoboda /branches/tracing/kernel/generic/ Convert kb_cleanup_lock to a mutex  
3018 5914 d 18 h svoboda /branches/tracing/ Isolate udebug-related thread_t fields into udebug_thread_t  
3015 5915 d 0 h svoboda /branches/tracing/kernel/generic/ Call udebug_stoppable_begin() after scheduling, rather than before - avoid restricted contex.  
2902 5931 d 2 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 5931 d 16 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 5941 d 0 h svoboda /branches/tracing/kernel/generic/ Verify that thread is waiting in syscall event when reading syscall args  
2848 5959 d 23 h svoboda /branches/tracing/kernel/generic/ Use debug_lock in thread struct for finer locking, to avoid problems with waitq_wakeup  
2839 5960 d 17 h svoboda /branches/tracing/kernel/generic/ Add thread_attach_by_id() and use it to do ipc_connect_kbox() with proper locking  
2827 5965 d 0 h svoboda /branches/tracing/kernel/generic/ Verify that a thread/task is in appropriate state when handling debug calls  
2826 5965 d 1 h svoboda /branches/tracing/kernel/generic/ Move debug_go_call from task struct to thread struct  
2825 5965 d 1 h svoboda /branches/tracing/kernel/generic/ Introduce task debug-states (udebug_task_state_t)  
2817 5965 d 16 h svoboda /branches/tracing/kernel/generic/ Add REGS_READ and REGS_WRITE debug methods to access userspace register state (no effect yet)  
2805 5967 d 19 h svoboda /branches/tracing/ add ipc call to retrieve syscall arguments  
2801 5968 d 2 h svoboda /branches/tracing/ [tracing] initial debug interface support  
2799 5968 d 3 h svoboda /branches/tracing/ Revert all changes in tracing branch (sync to r2785 of trunk)  
2787 5976 d 19 h decky /branches/tracing/ add dynamic linking, debugging and tracing branch  
2502 6218 d 21 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 6273 d 15 h jermar /trunk/kernel/generic/ JoinMe -> Lingering  
2446 6276 d 19 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 6277 d 14 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 6320 d 16 h jermar /trunk/kernel/generic/ Document and assert proper usage of THREAD_FLAG_WIRED.
Original patch by Jan Hudecek.
 
2216 6331 d 15 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls
 
2187 6332 d 22 h decky /trunk/kernel/generic/ add syscall for getting current thread ID  
2109 6393 d 23 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 6394 d 22 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 6399 d 15 h decky /trunk/kernel/generic/include/ move timeout_t to timeout.h
move other helper types to thread.h
 
2096 6399 d 17 h decky /trunk/kernel/generic/include/ move thread_t to thread.h  
2093 6399 d 18 h decky /trunk/kernel/ spinlock extern declaration macro  
2089 6400 d 22 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2080 6406 d 23 h decky /trunk/kernel/generic/include/ another typedef to anonymous enum  
2071 6411 d 15 h jermar /trunk/ (c) versus (C)  
2042 6445 d 18 h decky /trunk/kernel/ introduce uncounted threads, whose accounting doesn't affect accumulated task accounting
run tests in kconsole thread again
 
2031 6446 d 23 h decky /trunk/kernel/generic/include/proc/ fix comment  
2030 6446 d 23 h decky /trunk/kernel/ thread CPU cycles accounting  
1888 6536 d 18 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.
 
1854 6553 d 0 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 6576 d 19 h decky /trunk/kernel/generic/ finish security context isolation  
1820 6584 d 12 h decky /trunk/kernel/generic/ initial security context support  
1787 6601 d 17 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6608 d 18 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).
