3819	5577 d 20 h	jermar	/trunk/	Introduce a new syscall: SYS_IPC_FORWARD_SLOW.
3488	5685 d 21 h	svoboda	/trunk/uspace/	Fix assorted warnings.
3438	5708 d 4 h	svoboda	/trunk/	Merge syscall tracer (trace) and relevant part of udebug interface from tracing to trunk.
3344	5735 d 21 h	jermar	/trunk/uspace/lib/libc/generic/	Change ipc_share_{in\|out}_start() to use the async framework.
3334	5740 d 1 h	jermar	/trunk/uspace/lib/libc/generic/	Let ipc_data_{read\|write}_start() use the async framework.
2820	5870 d 18 h	decky	/trunk/uspace/lib/libc/generic/	fix copy-paste typo
2678	5968 d 23 h	jermar	/trunk/uspace/	The IPC_M_SHARE_* and IPC_M_DATA_* calls pass through 3 stages. Rename the send, receive and deliver wrappers to names ending with 'start', 'receive' and 'finalize', respectively. This should make it clearer for dummies.
2677	5969 d 0 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	5969 d 6 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.
2663	5976 d 19 h	jermar	/trunk/uspace/	Reimplement VFS_READ using IPC_M_DATA_READ.
2662	5976 d 19 h	jermar	/trunk/	Add support for IPC_M_DATA_READ calls.
2660	5976 d 21 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().
2637	5995 d 20 h	cejka	/trunk/	Extended IPC_M_CONNECT_TO_ME to use 3 user defined parameters. Phone identifier is passed in ARG5.
2636	5997 d 19 h	jermar	/trunk/	Update comments wrt the previous commit. Minor formatting fixes.
2635	5997 d 20 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.
2622	6006 d 2 h	jermar	/trunk/	Add mode argument to IPC forward. This argument can be used to modify the way forward behaves.
2620	6008 d 7 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.
2619	6009 d 19 h	jermar	/trunk/	Modify ipc_answer_*() to make use of all six syscall arguments. The recommended means of answering calls is via the ipc_answer_m() macros (where m denotes the number of return arguments) that automatically decide between the fast register version or the slow universal version of ipc_answer().
2618	6010 d 7 h	jermar	/trunk/	Modify asynchronous IPC to make use of all six syscall arguments. The preferred means of asynchronous communication is now via the set of ipc_call_async_m() macros, where m is the number of payload arguments passed to the kernel. These macros will automatically decide between the fast and the universal slow version of ipc_call_async.
2615	6011 d 4 h	jermar	/trunk/	Modify synchronous IPC to make use of all six syscall arguments. The preferred means of synchronous communication is now via the set of ipc_call_sync_m_n() macros, where m is the number of payload arguments passed to the kernel and n is the number of return values. These macros will automatically decide between the fast and the universal slow version of ipc_call_sync.
