3203 6520 d 15 h svoboda /branches/dynload/ Move stuff related to running programs to a separate source file proc/program.c  
3191 6526 d 14 h svoboda /branches/dynload/ Merge latest trunk changes into dynload  
3190 6526 d 14 h svoboda /branches/dynload/ Remove vestiges of loading code coming from trunk  
3155 6540 d 10 h svoboda /branches/dynload/ Make loader less chatty and let init use it, instead of loading binaries itself.

3150 6540 d 14 h svoboda /branches/dynload/ Merge trunk changes up to r3090 into dynload (still broken)

3004 6561 d 12 h svoboda /branches/dynload/ A crude task_spawn() libc function to run a program. A tiny command-line application 'cli' to test it.  
3001 6562 d 12 h svoboda /branches/dynload/kernel/generic/ Kernel support for running programs from userspace.  
2927 6572 d 17 h decky /branches/dynload/ added dynload branch  
2802 6612 d 16 h jermar /trunk/kernel/generic/ Fix initialization of answerbox->task in ipc_answerbox_init.
Contributed by Jiri Svoboda.
 
2745 6650 d 15 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings
 
2712 6676 d 13 h decky /trunk/kernel/ prettyprint output  
2632 6738 d 2 h decky /trunk/kernel/generic/src/proc/ try to kill the tasks fewer times by introducing a delay in iterations  
2504 6863 d 8 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 6921 d 11 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.
 
2436 6923 d 7 h jermar /trunk/ Fix two memory leaks.

In kernel, kernel_uarg structure needs to be deallocated when a thread
with userspace context is destroyed.

In userspace, the return value of the SYS_THREAD_CREATE must be checked
for error conditions and in case of error, uarg and stack must be freed
up.
 
2227 6974 d 21 h decky /trunk/kernel/ start shutdown infrastructure  
2216 6976 d 7 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls
 
2183 6978 d 11 h jermar /trunk/kernel/generic/ Continue to de-oversynchronize the kernel.
- replace as->refcount with an atomic counter; accesses to this
reference counter are not to be done when the as->lock mutex is held;
this gets us rid of mutex_lock_active();

Remove the possibility of a deadlock between TLB shootdown and asidlock.
- get rid of mutex_lock_active() on as->lock
- when locking the asidlock spinlock, always do it conditionally and with
preemption disabled; in the unsuccessful case, enable interrupts and try again
- there should be no deadlock between TLB shootdown and the as->lock mutexes
- PLEASE REVIEW !!!

Add DEADLOCK_PROBE's to places where we have spinlock_trylock() loops.
 
2118 7037 d 12 h decky /trunk/kernel/generic/src/ explicit typecast, fix signed/unsigned comparison  
2109 7038 d 15 h jermar /trunk/kernel/generic/ Revert thread_interrupt_sleep() to waitq_interrupt_sleep().
I'd prefer that this, IMO, waitq related stuff stays together.
 
2089 7045 d 14 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2087 7046 d 10 h jermar /trunk/kernel/ Indentaion and formatting changes even Martin will like :-)  
2071 7056 d 6 h jermar /trunk/ (c) versus (C)  
2050 7085 d 17 h decky /trunk/kernel/ benchmarking with statistics (initial)  
2048 7088 d 8 h jermar /trunk/ Formatting and indentation changes.  
2042 7090 d 10 h decky /trunk/kernel/ introduce uncounted threads, whose accounting doesn't affect accumulated task accounting
run tests in kconsole thread again
 
2041 7090 d 12 h decky /trunk/kernel/generic/src/proc/ revert 2040  
2040 7090 d 13 h decky /trunk/kernel/generic/src/proc/ add forgotten btree_remove()  
2039 7090 d 14 h decky /trunk/kernel/generic/ accumulate task accounting, run tests as separate kernel task
