3819 5606 d 14 h jermar /trunk/ Introduce a new syscall: SYS_IPC_FORWARD_SLOW.  
3657 5662 d 22 h vana /trunk/ Legacy IRQ support, uspace NS16550 support, some minor changes  
3620 5669 d 23 h svoboda /trunk/kernel/generic/ Move stuff related to kbox to a separate struct.  
3603 5671 d 12 h svoboda /trunk/ Stoppability sections must be much smaller (design error). Also fix deadlock in udebug_stop(). Fix pause functionality in tracer.  
3496 5701 d 14 h svoboda /trunk/kernel/generic/src/ipc/ Split and streamline kbox_thread_proc().  
3495 5701 d 14 h svoboda /trunk/kernel/generic/src/ipc/ Synchronize properly when detaching kbox from within.  
3494 5703 d 13 h svoboda /trunk/kernel/generic/src/ipc/ Fix panic when debugged task quits. Also fix memory leak when debugger disconnects first.  
3476 5728 d 16 h jermar /trunk/kernel/generic/src/ipc/ Add comments documenting our treatment of the task's active call counter.  
3449 5735 d 14 h jermar /trunk/kernel/generic/src/ipc/ Fix task active call accounting for IPC_M_HUNGUP calls.  
3445 5736 d 13 h jermar /trunk/kernel/ Rename ipc/ipc_kbox.c to ipc/kbox.c.  
3441 5736 d 20 h svoboda /trunk/kernel/generic/src/ Use LOG() instead of printf() for debug messages.  
3438 5736 d 22 h svoboda /trunk/ Merge syscall tracer (trace) and relevant part of udebug interface from tracing to trunk.  
3395 5744 d 15 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 5745 d 13 h jermar /trunk/kernel/generic/src/ipc/ cstyle for ipc.c  
3370 5757 d 13 h jermar /trunk/kernel/generic/ Synchronous IPC must be interruptible.  
3363 5760 d 15 h jermar /trunk/kernel/generic/src/ipc/ Demasquerade the caller phone during ipc_answer_n() rather than in
ipc_wait_for_call().
 
3362 5760 d 16 h jermar /trunk/kernel/generic/ Fix processing of answers to forwarded masqueraded calls.  
3332 5768 d 20 h jermar /trunk/kernel/generic/src/ipc/ Fix types when processing IPC_M_DATA_WRITE arguments.  
3186 5822 d 15 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 5823 d 18 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 5840 d 3 h svoboda /trunk/kernel/ Declare arguments for memstr.h operations as pointers instead of uintptr_t.  
3090 5842 d 19 h decky /trunk/kernel/generic/src/ipc/ revert coding style change  
3054 5842 d 19 h decky /trunk/kernel/generic/src/ipc/ proper printf formatting  
3020 5848 d 13 h jermar /trunk/kernel/generic/ Turn phone->lock into mutex.  
2934 5861 d 16 h jermar /trunk/ Do not attempt to malloc() zero bytes of memory during VFS_READ at end of file.  
2802 5901 d 23 h jermar /trunk/kernel/generic/ Fix initialization of answerbox->task in ipc_answerbox_init.
Contributed by Jiri Svoboda.
 
2745 5939 d 22 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings
 
2677 5997 d 17 h jermar /trunk/ Rename IPC_M_AS_AREA_SEND to IPC_M_SHARE_OUT. Rename IPC_M_AS_AREA_RECV to
IPC_M_SHARE_IN. Provide user-friendly wrappers for these methods so that even
dummies can get it right. Some applications using simpler protocols still use
these methods directly.
 
2676 5998 d 0 h jermar /trunk/ Simplify the IPC_M_DATA_WRITE protocol. Do not pass the source address space
virtual address to the recipient. This feature was not used anyway. Now
IPC_M_DATA_WRITE and IPC_M_DATA_READ are feature-aligned.
 
2662 6005 d 13 h jermar /trunk/ Add support for IPC_M_DATA_READ calls.  
2661 6005 d 14 h jermar /trunk/kernel/generic/src/ipc/ Release the IPC_M_DATA_WRITE buffer even if the write is refused by the
recipient.
 
2660 6005 d 14 h jermar /trunk/ Rename IPC_M_DATA_SEND to IPC_M_DATA_WRITE. Now, when we also add
IPC_M_DATA_READ, it will not clash and cause confusion with userspace wrappers
such as ipc_data_receive(). Rename the forementioned wrappers to
ipc_data_write_send(), ipc_data_write_receive() and ipc_data_write_deliver().
 
2638 6024 d 14 h jermar /trunk/ Sync IPC comments with IPC code.  
2637 6024 d 14 h cejka /trunk/ Extended IPC_M_CONNECT_TO_ME to use 3 user defined parameters.
Phone identifier is passed in ARG5.
 
2636 6026 d 13 h jermar /trunk/ Update comments wrt the previous commit.
Minor formatting fixes.
 
2635 6026 d 14 h cejka /trunk/ Function ipc_connect_me_to sends 3 user defined arguments now.
One argument added also to ipc_forward_fast.
Fixed devmap and improved its test.
 
2626 6034 d 0 h jermar /trunk/kernel/generic/ Support for 5 payload arguments for IPC irq notifications and the pseudo code.  
2623 6034 d 20 h jermar /trunk/kernel/generic/ Introduce the IPC_FF_ROUTE_FROM_ME forwarding flag.  
2622 6034 d 20 h jermar /trunk/ Add mode argument to IPC forward.
This argument can be used to modify the way forward behaves.
 
2620 6037 d 1 h jermar /trunk/ Be more deterministic when a user accidently uses fast version of IPC
call/answer instead of the full one and passes fewer arguments than required by
the recipient of the call/response.

and the recipient interprets arguments that
were actually not passed by the sender.
