2809 5890 d 22 h svoboda /branches/tracing/ add call to read the debugged task's memory  
2808 5891 d 12 h svoboda /branches/tracing/ add kernel answerbox+thread to mediate access to task's memory  
2801 5892 d 23 h svoboda /branches/tracing/ [tracing] initial debug interface support  
2800 5892 d 23 h svoboda /branches/tracing/kernel/generic/ [tracing] fix initialiation of answerbox->task in ipc_answerbox_init  
2787 5901 d 16 h decky /branches/tracing/ add dynamic linking, debugging and tracing branch  
2662 5996 d 11 h jermar /trunk/ Add support for IPC_M_DATA_READ calls.  
2637 6015 d 12 h cejka /trunk/ Extended IPC_M_CONNECT_TO_ME to use 3 user defined parameters.
Phone identifier is passed in ARG5.
 
2623 6025 d 18 h jermar /trunk/kernel/generic/ Introduce the IPC_FF_ROUTE_FROM_ME forwarding flag.  
2622 6025 d 18 h jermar /trunk/ Add mode argument to IPC forward.
This argument can be used to modify the way forward behaves.
 
2601 6038 d 15 h jermar /trunk/kernel/generic/src/ipc/ Fix and improve two IPC related comments.  
2494 6161 d 12 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 6185 d 13 h jermar /trunk/kernel/generic/src/ipc/ Some left-over stuff from the last commit (IPC cleanup and improved
comments.)
 
2471 6185 d 13 h jermar /trunk/ Greatly improve comments in the IPC layer.
Now I think I finally start to understand our IPC internals :-)
 
2310 6226 d 13 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 6256 d 12 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls
 
2183 6258 d 16 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 6336 d 12 h jermar /trunk/ (c) versus (C)  
1933 6428 d 11 h jermar /trunk/kernel/generic/ Implement efficient IPC notification cleanup.  
1923 6429 d 11 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 6526 d 14 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot
