2902 5885 d 17 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 5895 d 5 h svoboda /branches/tracing/kernel/generic/ Terminate debugging session on debugger disconnect  
2840 5915 d 8 h svoboda /branches/tracing/kernel/generic/src/ipc/ Fix: Clear kb_thread_at_hand when terminating kbox thread  
2839 5915 d 9 h svoboda /branches/tracing/kernel/generic/ Add thread_attach_by_id() and use it to do ipc_connect_kbox() with proper locking  
2837 5915 d 15 h svoboda /branches/tracing/ Handle hangup message sent to kbox. Exit kbox thread when the last phone has been disconnected.  
2836 5915 d 16 h svoboda /branches/tracing/kernel/generic/src/ipc/ Fix: only create kbox thread if it doesn't exist yet  
2815 5920 d 11 h svoboda /branches/tracing/kernel/generic/ Move kernelbox debug message handling to udebug/udebug_ipc.c  
2813 5920 d 14 h svoboda /branches/tracing/ Move debug call preprocessing from ipc/sysipc.c to udebug/udebug_ipc.c  
2812 5920 d 15 h svoboda /branches/tracing/ Group debug IPC calls under a single method number, differentiate by ARG1  
2809 5920 d 16 h svoboda /branches/tracing/ add call to read the debugged task's memory  
2808 5921 d 7 h svoboda /branches/tracing/ add kernel answerbox+thread to mediate access to task's memory  
2801 5922 d 17 h svoboda /branches/tracing/ [tracing] initial debug interface support  
2800 5922 d 17 h svoboda /branches/tracing/kernel/generic/ [tracing] fix initialiation of answerbox->task in ipc_answerbox_init  
2787 5931 d 10 h decky /branches/tracing/ add dynamic linking, debugging and tracing branch  
2662 6026 d 5 h jermar /trunk/ Add support for IPC_M_DATA_READ calls.  
2637 6045 d 7 h cejka /trunk/ Extended IPC_M_CONNECT_TO_ME to use 3 user defined parameters.
Phone identifier is passed in ARG5.
 
2623 6055 d 12 h jermar /trunk/kernel/generic/ Introduce the IPC_FF_ROUTE_FROM_ME forwarding flag.  
2622 6055 d 12 h jermar /trunk/ Add mode argument to IPC forward.
This argument can be used to modify the way forward behaves.
 
2601 6068 d 9 h jermar /trunk/kernel/generic/src/ipc/ Fix and improve two IPC related comments.  
2494 6191 d 6 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 6215 d 7 h jermar /trunk/kernel/generic/src/ipc/ Some left-over stuff from the last commit (IPC cleanup and improved
comments.)
 
2471 6215 d 7 h jermar /trunk/ Greatly improve comments in the IPC layer.
Now I think I finally start to understand our IPC internals :-)
 
2310 6256 d 8 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 6286 d 7 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls
 
2183 6288 d 10 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 6366 d 6 h jermar /trunk/ (c) versus (C)  
1933 6458 d 5 h jermar /trunk/kernel/generic/ Implement efficient IPC notification cleanup.  
1923 6459 d 6 h jermar /trunk/ Replace the old IRQ dispatcher and IPC notifier with new implementation.
Note that all architectures except for sparc64 are now broken
and don't even compile.
 
1787 6556 d 8 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6563 d 9 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1757 6577 d 14 h jermar /kernel/trunk/ Cleanup of comments.  
1735 6579 d 16 h decky /kernel/trunk/ make kernel prints case consistent  
1708 6581 d 15 h jermar /kernel/trunk/ Fix some broken doxygen comments.  
1705 6583 d 15 h cejka /kernel/trunk/ Added file with modules definitions and descriptions.
We are able to change modules order and their description in one place.
 
1702 6584 d 12 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1595 6591 d 19 h palkovsky /kernel/trunk/ Added kernel circular buffer klog.
Added automatic killing of tasks raising inappropriate exceptions.
TODO: Fix vsnprintf return value(and behaviour according to specs) and remove workaround in klog.
 
1591 6592 d 4 h palkovsky /kernel/trunk/generic/ Small updates to ipc.  
1582 6592 d 16 h palkovsky /kernel/trunk/generic/ Modified ipc_cleanup.  
1573 6593 d 9 h palkovsky /kernel/trunk/generic/ Renamed some things in IPC to be consistent.
Added ipc reporting to kconsole.
 
1568 6593 d 11 h palkovsky /kernel/trunk/generic/ Slightly remodelled ipc hangups to facilitate correct cleanup.
Doc updates for frame allocator.
