3035 5837 d 13 h svoboda /branches/tracing/kernel/generic/ Use thread_join() to wait for kbox thread termination, instead of specific wait queue.  
3034 5837 d 15 h svoboda /branches/tracing/kernel/generic/ Convert kb_cleanup_lock to a mutex  
3033 5838 d 4 h svoboda /branches/tracing/kernel/generic/src/ipc/ Fix tasks_lock being released too soon in ipc_connect_kbox()  
3014 5840 d 16 h svoboda /branches/tracing/kernel/generic/ Isolate udebug-related task_t fields into udebug_task_t.  
2913 5856 d 7 h svoboda /branches/tracing/kernel/generic/src/ Print less debugging messages to make things go faster  
2902 5856 d 15 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  
2870 5866 d 3 h svoboda /branches/tracing/kernel/generic/ Terminate debugging session on debugger disconnect  
2840 5886 d 7 h svoboda /branches/tracing/kernel/generic/src/ipc/ Fix: Clear kb_thread_at_hand when terminating kbox thread  
2839 5886 d 7 h svoboda /branches/tracing/kernel/generic/ Add thread_attach_by_id() and use it to do ipc_connect_kbox() with proper locking  
2837 5886 d 13 h svoboda /branches/tracing/ Handle hangup message sent to kbox. Exit kbox thread when the last phone has been disconnected.  
2836 5886 d 15 h svoboda /branches/tracing/kernel/generic/src/ipc/ Fix: only create kbox thread if it doesn't exist yet  
2815 5891 d 9 h svoboda /branches/tracing/kernel/generic/ Move kernelbox debug message handling to udebug/udebug_ipc.c  
2813 5891 d 12 h svoboda /branches/tracing/ Move debug call preprocessing from ipc/sysipc.c to udebug/udebug_ipc.c  
2812 5891 d 13 h svoboda /branches/tracing/ Group debug IPC calls under a single method number, differentiate by ARG1  
2809 5891 d 15 h svoboda /branches/tracing/ add call to read the debugged task's memory  
2808 5892 d 5 h svoboda /branches/tracing/ add kernel answerbox+thread to mediate access to task's memory  
2801 5893 d 15 h svoboda /branches/tracing/ [tracing] initial debug interface support  
2800 5893 d 16 h svoboda /branches/tracing/kernel/generic/ [tracing] fix initialiation of answerbox->task in ipc_answerbox_init  
2787 5902 d 9 h decky /branches/tracing/ add dynamic linking, debugging and tracing branch  
2662 5997 d 4 h jermar /trunk/ Add support for IPC_M_DATA_READ calls.  
2637 6016 d 5 h cejka /trunk/ Extended IPC_M_CONNECT_TO_ME to use 3 user defined parameters.
Phone identifier is passed in ARG5.		  
2623 6026 d 11 h jermar /trunk/kernel/generic/ Introduce the IPC_FF_ROUTE_FROM_ME forwarding flag.  
2622 6026 d 11 h jermar /trunk/ Add mode argument to IPC forward.
This argument can be used to modify the way forward behaves.		  
2601 6039 d 8 h jermar /trunk/kernel/generic/src/ipc/ Fix and improve two IPC related comments.  
2494 6162 d 5 h jermar /trunk/kernel/generic/ Implement a new mechanism for copying data between two address spaces based on
IPC. New system method IPC_M_DATA_SEND is introduced. The implementation is
generic and does not make use of any possible architecture optimizations such as
direct copy from one address space to another.		  
2472 6186 d 5 h jermar /trunk/kernel/generic/src/ipc/ Some left-over stuff from the last commit (IPC cleanup and improved
comments.)		  
2471 6186 d 6 h jermar /trunk/ Greatly improve comments in the IPC layer.
Now I think I finally start to understand our IPC internals :-)		  
2310 6227 d 6 h jermar /trunk/kernel/generic/ Cleanup the waitq_wakeup() interface.
Replace numeric constants (i.e. 0)
and boolean constants (i.e. false) with
more readable WAKEUP_FIRST. Also change the
type of the second argument of waitq_wakeup()
to a newly introduced type wakeup_mode_t.

Fix behaviour of waitq_wakeup() in case
that WAKEUP_ALL semantics is required
but no threads are sleeping in the wait
queue. This is a similar fix to that of
Jan Hudecek committed in the RCU branch,
but, IMHO, is more straightforward and
also doesn't eat up previous missed
wakeups.		  
2216 6257 d 5 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls		  
2183 6259 d 9 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.		  
2071 6337 d 5 h jermar /trunk/ (c) versus (C)  
1933 6429 d 4 h jermar /trunk/kernel/generic/ Implement efficient IPC notification cleanup.
