3386 5744 d 9 h decky /branches/network/ add new network branch (copy of current trunk)  
3370 5751 d 4 h jermar /trunk/kernel/generic/ Synchronous IPC must be interruptible.  
3363 5754 d 7 h jermar /trunk/kernel/generic/src/ipc/ Demasquerade the caller phone during ipc_answer_n() rather than in
ipc_wait_for_call().		  
3362 5754 d 7 h jermar /trunk/kernel/generic/ Fix processing of answers to forwarded masqueraded calls.  
3186 5816 d 7 h jermar /trunk/kernel/ Support for active mutexes. Active mutexes implement busy waiting, pretty much
in the same way as spinlocks, but can be passed to condition variables, which is
the motivation for this enhancement.		  
3184 5817 d 10 h jermar /trunk/kernel/generic/src/ipc/ Fix a scary two-year old bug: do not attempt to initialize a call structure if
its allocation failed.		  
3104 5833 d 18 h svoboda /trunk/kernel/ Declare arguments for memstr.h operations as pointers instead of uintptr_t.  
3090 5836 d 10 h decky /trunk/kernel/generic/src/ipc/ revert coding style change  
3054 5836 d 11 h decky /trunk/kernel/generic/src/ipc/ proper printf formatting  
3020 5842 d 5 h jermar /trunk/kernel/generic/ Turn phone->lock into mutex.  
2802 5895 d 14 h jermar /trunk/kernel/generic/ Fix initialization of answerbox->task in ipc_answerbox_init.
Contributed by Jiri Svoboda.		  
2662 5999 d 4 h jermar /trunk/ Add support for IPC_M_DATA_READ calls.  
2637 6018 d 6 h cejka /trunk/ Extended IPC_M_CONNECT_TO_ME to use 3 user defined parameters.
Phone identifier is passed in ARG5.		  
2623 6028 d 11 h jermar /trunk/kernel/generic/ Introduce the IPC_FF_ROUTE_FROM_ME forwarding flag.  
2622 6028 d 11 h jermar /trunk/ Add mode argument to IPC forward.
This argument can be used to modify the way forward behaves.		  
2601 6041 d 8 h jermar /trunk/kernel/generic/src/ipc/ Fix and improve two IPC related comments.  
2494 6164 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 6188 d 6 h jermar /trunk/kernel/generic/src/ipc/ Some left-over stuff from the last commit (IPC cleanup and improved
comments.)		  
2471 6188 d 6 h jermar /trunk/ Greatly improve comments in the IPC layer.
Now I think I finally start to understand our IPC internals :-)		  
2310 6229 d 7 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.
