4405 5697 d 20 h jermar /trunk/kernel/generic/src/ipc/ Do not test the same condition twice.  
4252 5740 d 22 h decky /trunk/kernel/ move event notification to the ipc directory (where it probably belogs to, side-by-side to IRQ notifications)
cleanup the notification code a little bit (there is probably no need to allocate two structured dynamically)		  
4173 5754 d 20 h jermar /trunk/ Revive kernel notifications.  
3476 5933 d 23 h jermar /trunk/kernel/generic/src/ipc/ Add comments documenting our treatment of the task's active call counter.  
3449 5940 d 21 h jermar /trunk/kernel/generic/src/ipc/ Fix task active call accounting for IPC_M_HUNGUP calls.  
3445 5941 d 21 h jermar /trunk/kernel/ Rename ipc/ipc_kbox.c to ipc/kbox.c.  
3438 5942 d 5 h svoboda /trunk/ Merge syscall tracer (trace) and relevant part of udebug interface from tracing to trunk.  
3395 5949 d 22 h jermar /trunk/kernel/generic/ Kernel's ipc_data_t and uspace's ipc_call_t must be in sync.

This commit fixes a problem introduced in revision 3362, when
ipc_data_t was enlarged by the caller_phone member. This resulted
in sys_ipc_wait_for_call() passing larger structure to uspace
than requested, leading to a random damage of userspace memory.		  
3394 5950 d 20 h jermar /trunk/kernel/generic/src/ipc/ cstyle for ipc.c  
3370 5962 d 21 h jermar /trunk/kernel/generic/ Synchronous IPC must be interruptible.  
3363 5965 d 23 h jermar /trunk/kernel/generic/src/ipc/ Demasquerade the caller phone during ipc_answer_n() rather than in
ipc_wait_for_call().		  
3362 5965 d 23 h jermar /trunk/kernel/generic/ Fix processing of answers to forwarded masqueraded calls.  
3186 6027 d 23 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 6029 d 2 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 6045 d 10 h svoboda /trunk/kernel/ Declare arguments for memstr.h operations as pointers instead of uintptr_t.  
3090 6048 d 2 h decky /trunk/kernel/generic/src/ipc/ revert coding style change  
3054 6048 d 3 h decky /trunk/kernel/generic/src/ipc/ proper printf formatting  
3020 6053 d 21 h jermar /trunk/kernel/generic/ Turn phone->lock into mutex.  
2802 6107 d 6 h jermar /trunk/kernel/generic/ Fix initialization of answerbox->task in ipc_answerbox_init.
Contributed by Jiri Svoboda.		  
2662 6210 d 20 h jermar /trunk/ Add support for IPC_M_DATA_READ calls.
