2839 5925 d 18 h svoboda /branches/tracing/kernel/generic/ Add thread_attach_by_id() and use it to do ipc_connect_kbox() with proper locking  
2826 5930 d 2 h svoboda /branches/tracing/kernel/generic/ Move debug_go_call from task struct to thread struct  
2825 5930 d 2 h svoboda /branches/tracing/kernel/generic/ Introduce task debug-states (udebug_task_state_t)  
2808 5931 d 16 h svoboda /branches/tracing/ add kernel answerbox+thread to mediate access to task's memory  
2804 5932 d 22 h svoboda /branches/tracing/kernel/generic/ allow for attaching to tasks with sleeping threads  
2801 5933 d 2 h svoboda /branches/tracing/ [tracing] initial debug interface support  
2799 5933 d 4 h svoboda /branches/tracing/ Revert all changes in tracing branch (sync to r2785 of trunk)  
2787 5941 d 20 h decky /branches/tracing/ add dynamic linking, debugging and tracing branch  
2504 6183 d 17 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 6241 d 20 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 6295 d 6 h decky /trunk/kernel/ start shutdown infrastructure  
2216 6296 d 16 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls		  
2106 6359 d 23 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 6363 d 23 h decky /trunk/kernel/ move ipc structures to ipc.h  
2103 6364 d 16 h decky /trunk/kernel/generic/include/ move timeout_t to timeout.h
move other helper types to thread.h		  
2096 6364 d 18 h decky /trunk/kernel/generic/include/ move thread_t to thread.h  
2093 6364 d 19 h decky /trunk/kernel/ spinlock extern declaration macro  
2092 6364 d 20 h decky /trunk/kernel/generic/include/ move cpu_t to cpu.h  
2090 6365 d 19 h decky /trunk/kernel/generic/include/proc/ cleanup garbage  
2089 6365 d 23 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2071 6376 d 16 h jermar /trunk/ (c) versus (C)  
2039 6411 d 0 h decky /trunk/kernel/generic/ accumulate task accounting, run tests as separate kernel task  
1888 6501 d 19 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1820 6549 d 13 h decky /trunk/kernel/generic/ initial security context support  
1787 6566 d 18 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6573 d 19 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1702 6594 d 22 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1587 6602 d 19 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 6602 d 22 h jermar /kernel/trunk/generic/ Kill task when its main thread exits.  
1583 6603 d 1 h jermar /kernel/trunk/generic/ Make ktaskclnp call ipc_cleanup and futex_cleanup.  
1579 6603 d 14 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 6603 d 20 h palkovsky /kernel/trunk/generic/ Slightly remodelled ipc hangups to facilitate correct cleanup.
Doc updates for frame allocator.		  
1468 6607 d 20 h jermar /kernel/trunk/ Function for destroying address space for which there is no other reference in the kernel.  
1460 6608 d 0 h jermar /kernel/trunk/generic/ Reference counting for futexes.  
1358 6622 d 19 h jermar /kernel/trunk/generic/ Cleanup after removal of as_area_accept and as_area_send.  
1235 6643 d 0 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 6645 d 20 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 6655 d 19 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 6655 d 21 h jermar /kernel/trunk/ Add task_create_arch() for all architectures.  
1184 6655 d 22 h jermar /kernel/trunk/ Move arch/thread.h to arch/proc/thread.h on all architectures.
Replace ARCH_THREAD_DATA with new thread_arch_t arch on all architectures.
Similarily, add task_arch_t arch on all architectures.
On amd64 and ia32, grow the TSS segment by 64K + 1B to support IO port
permission bitmap. For the same reason, define per task IO port permission bitmaps
on ia32 and amd64.
