4344 5548 d 1 h svoboda /branches/dynload/ Merge trunk changes up to r3988 to dynload.  
3674 5693 d 0 h svoboda /branches/dynload/ Merge latest trunk changes to dynload.  
3569 5720 d 11 h svoboda /branches/dynload/ Merge latest trunk changes into dynload.  
3448 5771 d 13 h svoboda /branches/dynload/ Merge latest trunk changes into dynload  
3203 5845 d 10 h svoboda /branches/dynload/ Move stuff related to running programs to a separate source file proc/program.c  
3190 5851 d 9 h svoboda /branches/dynload/ Remove vestiges of loading code coming from trunk  
3149 5865 d 9 h svoboda /branches/dynload/ Merge trunk changes up to r3071 into dynload (broken)  
3004 5886 d 7 h svoboda /branches/dynload/ A crude task_spawn() libc function to run a program. A tiny command-line application 'cli' to test it.  
3001 5887 d 8 h svoboda /branches/dynload/kernel/generic/ Kernel support for running programs from userspace.  
2927 5897 d 13 h decky /branches/dynload/ added dynload branch  
2504 6188 d 3 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 6246 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.
 
2227 6299 d 16 h decky /trunk/kernel/ start shutdown infrastructure  
2216 6301 d 2 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls
 
2106 6364 d 9 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 6368 d 10 h decky /trunk/kernel/ move ipc structures to ipc.h  
2103 6369 d 2 h decky /trunk/kernel/generic/include/ move timeout_t to timeout.h
move other helper types to thread.h
 
2096 6369 d 4 h decky /trunk/kernel/generic/include/ move thread_t to thread.h  
2093 6369 d 5 h decky /trunk/kernel/ spinlock extern declaration macro  
2092 6369 d 6 h decky /trunk/kernel/generic/include/ move cpu_t to cpu.h  
2090 6370 d 5 h decky /trunk/kernel/generic/include/proc/ cleanup garbage  
2089 6370 d 9 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2071 6381 d 2 h jermar /trunk/ (c) versus (C)  
2039 6415 d 10 h decky /trunk/kernel/generic/ accumulate task accounting, run tests as separate kernel task  
1888 6506 d 5 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.
 
1820 6553 d 23 h decky /trunk/kernel/generic/ initial security context support  
1787 6571 d 4 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6578 d 5 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1702 6599 d 8 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1587 6607 d 5 h jermar /kernel/trunk/ task_destroy() implementation, fixes in as_destroy() and task_kill().
This is the first version of HelenOS that would perform complete cleanup leading from thread to destruction of address space.
 
1585 6607 d 8 h jermar /kernel/trunk/generic/ Kill task when its main thread exits.  
1583 6607 d 11 h jermar /kernel/trunk/generic/ Make ktaskclnp call ipc_cleanup and futex_cleanup.  
1579 6608 d 1 h jermar /kernel/trunk/generic/ Framework for task_kill().
Some pieces (e.g. implementation of ktask_cleanup() kernel thread and
task_destroy() function) are missing.
Changed locking order for task lock, threads_lock and thread lock from
threads_lock, thread lock, task lock to task lock, threads_lock, thread lock.
 
1568 6608 d 7 h palkovsky /kernel/trunk/generic/ Slightly remodelled ipc hangups to facilitate correct cleanup.
Doc updates for frame allocator.
 
1468 6612 d 6 h jermar /kernel/trunk/ Function for destroying address space for which there is no other reference in the kernel.  
1460 6612 d 10 h jermar /kernel/trunk/generic/ Reference counting for futexes.  
1358 6627 d 5 h jermar /kernel/trunk/generic/ Cleanup after removal of as_area_accept and as_area_send.  
1235 6647 d 11 h jermar /kernel/trunk/generic/ Implementation of SYS_AS_AREA_ACCEPT and SYS_AS_AREA_SEND syscalls.
Note that these replace previously declared SYS_AS_AREA_SHARE_APPROVE
and SYS_AS_AREA_SHARE_PERFORM.
 
1227 6650 d 6 h jermar /kernel/trunk/ Reorganize syscall names to better correspond to kernel architecture.
Add dummy placeholders for SYS_AS_AREA_SHARE_APPROVE and
SYS_AS_AREA_SHARE_PERFORM syscalls.
 
1187 6660 d 5 h jermar /kernel/trunk/ Cleanup pm.c and pm.h code on ia32 and amd64.
Add before_task_runs() and before_task_runs_arch() for each architecture.
Add ia32 and amd64 code to ensure I/O Permission Bitmap update.
