2870 5927 d 22 h svoboda /branches/tracing/kernel/generic/ Terminate debugging session on debugger disconnect  
2839 5948 d 2 h svoboda /branches/tracing/kernel/generic/ Add thread_attach_by_id() and use it to do ipc_connect_kbox() with proper locking  
2826 5952 d 10 h svoboda /branches/tracing/kernel/generic/ Move debug_go_call from task struct to thread struct  
2825 5952 d 10 h svoboda /branches/tracing/kernel/generic/ Introduce task debug-states (udebug_task_state_t)  
2808 5954 d 0 h svoboda /branches/tracing/ add kernel answerbox+thread to mediate access to task's memory  
2804 5955 d 6 h svoboda /branches/tracing/kernel/generic/ allow for attaching to tasks with sleeping threads  
2801 5955 d 10 h svoboda /branches/tracing/ [tracing] initial debug interface support  
2799 5955 d 11 h svoboda /branches/tracing/ Revert all changes in tracing branch (sync to r2785 of trunk)  
2787 5964 d 4 h decky /branches/tracing/ add dynamic linking, debugging and tracing branch  
2504 6206 d 1 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 6264 d 4 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 6317 d 14 h decky /trunk/kernel/ start shutdown infrastructure  
2216 6319 d 0 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls		  
2106 6382 d 7 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 6386 d 7 h decky /trunk/kernel/ move ipc structures to ipc.h  
2103 6387 d 0 h decky /trunk/kernel/generic/include/ move timeout_t to timeout.h
move other helper types to thread.h		  
2096 6387 d 2 h decky /trunk/kernel/generic/include/ move thread_t to thread.h  
2093 6387 d 3 h decky /trunk/kernel/ spinlock extern declaration macro  
2092 6387 d 4 h decky /trunk/kernel/generic/include/ move cpu_t to cpu.h  
2090 6388 d 3 h decky /trunk/kernel/generic/include/proc/ cleanup garbage  
2089 6388 d 6 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2071 6398 d 23 h jermar /trunk/ (c) versus (C)  
2039 6433 d 7 h decky /trunk/kernel/generic/ accumulate task accounting, run tests as separate kernel task  
1888 6524 d 3 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1820 6571 d 20 h decky /trunk/kernel/generic/ initial security context support  
1787 6589 d 1 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6596 d 3 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1702 6617 d 5 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1587 6625 d 2 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 6625 d 6 h jermar /kernel/trunk/generic/ Kill task when its main thread exits.  
1583 6625 d 9 h jermar /kernel/trunk/generic/ Make ktaskclnp call ipc_cleanup and futex_cleanup.  
1579 6625 d 22 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 6626 d 4 h palkovsky /kernel/trunk/generic/ Slightly remodelled ipc hangups to facilitate correct cleanup.
Doc updates for frame allocator.		  
1468 6630 d 3 h jermar /kernel/trunk/ Function for destroying address space for which there is no other reference in the kernel.  
1460 6630 d 7 h jermar /kernel/trunk/generic/ Reference counting for futexes.  
1358 6645 d 3 h jermar /kernel/trunk/generic/ Cleanup after removal of as_area_accept and as_area_send.  
1235 6665 d 8 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 6668 d 4 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 6678 d 2 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.		  
1185 6678 d 5 h jermar /kernel/trunk/ Add task_create_arch() for all architectures.
