2637	6000 d 11 h	cejka	/trunk/	Extended IPC_M_CONNECT_TO_ME to use 3 user defined parameters. Phone identifier is passed in ARG5.
2619	6014 d 10 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().
2600	6023 d 18 h	jermar	/trunk/uspace/srv/vfs/	VFS work. vfs_grab_phone() must disable fibril preemption in order to avoid deadlock with other fibrils of the same thread that might be trying to vfs_grab_phone() too.
2590	6031 d 14 h	jermar	/trunk/uspace/srv/vfs/	VFS work. Start implementing VFS side of VFS_OPEN. Add vfs_node.c to contain VFS node related internal functions.
2588	6031 d 16 h	jermar	/trunk/uspace/	Add ipc_answer_fast_[01] macros so that ipc_answer_fast() users don't have to write zero arguments all the time.
2576	6039 d 11 h	jermar	/trunk/uspace/srv/vfs/	Specify the width of the printed text in an argument to printf().
2567	6063 d 0 h	jermar	/trunk/uspace/srv/vfs/	Don't explicitly answer the IPC_M_DATA_SEND call in VFS_REGISTER. It is done automatically in ipc_data_deliver().
2549	6067 d 16 h	jermar	/trunk/uspace/srv/vfs/	VFS work. Modify vfs_lookup_internal() to be able to work with an alternate root. This will be useful for VFS_MOUNT support. Improve observability and debuggability by explicitly zeroing out PLB after the path has been looked up.
2548	6067 d 17 h	jermar	/trunk/uspace/srv/vfs/	VFS work. Add fs_name_to_handle() function to abstract away the details of walking the list of registered file systems, and in order to avoid code duplication.
2546	6067 d 21 h	jermar	/trunk/uspace/srv/	VFS work. Upon FS registration via VFS_REGISTER, the client is assigned a unique file system handle. When generating the VFS_LOOKUP request in VFS, we also need to pass the device handle. Add function to transform file system handle to phone. Implement basic multi-call VFS request serialization on VFS side.
2543	6068 d 16 h	jermar	/trunk/uspace/srv/	VFS work. Modify the protocol so that VFS and FAT (or any other FS) have to share the Path Lookup Buffer in read-only mode.
2536	6073 d 11 h	jermar	/trunk/uspace/srv/	VFS work. Describe the bottleneck of one VFS-FS connection in fat.c. Add a comment outlining possible approaches. Also in fat.c, the async_create_manager() _must_ be called as well as async_set_client_connection(). The latter alows VFS to duplicate the connection. Modify fat_connection() to ACK all IPC_M_CONNECT_ME_TO calls.
2535	6075 d 14 h	jermar	/trunk/uspace/srv/vfs/	Move VFS_REGISTER functionality into a separate file.
2532	6076 d 12 h	jermar	/trunk/	VFS work. The VFS_REGISTER is now fully implemented by both vfs and fat servers. Thanks to the debugging dprintf()'s, I was able to fix little errors here and there to make them actually work. Modified vfs and fat service makefiles so that the two are not built as drivers and can therefore print to standard output. Added many debugging dprintf()'s. Change the amd64 boot configuration to load vfs and fat.
2531	6077 d 11 h	jermar	/trunk/uspace/	VFS work. Implement VFS_REGISTER part of the protocol in the FAT file system. IPC work. Rename ipc_data_send_accept() to ipc_data_receive() and ipc_data_send_answer() to ipc_data_deliver(). Introduce ipc_data_send().
2527	6079 d 20 h	jermar	/trunk/	VFS work. Added mandatory VFS_LOOKUP Handling of VFS_REGISTER request should be now more or less complete. Added code that inserts the new fs_info structure into the list of registered filesystems and creates a callback connection to the client FS.
2526	6080 d 16 h	jermar	/trunk/uspace/	VFS work. Delve deeper into VFS_REGISTER.
2523	6080 d 22 h	jermar	/trunk/	VFS work. Now, each VFS connection fibril will accept requests in a loop. The idea is that each connection will be potentially reused for multiple requests before it is closed by the server. More VFS_REGISTER bits. Make use of the IPC_M_DATA_SEND wrappers introduced in the previous commit. Add enum members for more VFS operations.
2521	6082 d 11 h	jermar	/trunk/uspace/srv/vfs/	VFS work. Start implementing the VFS_REGISTER request.
2520	6082 d 12 h	jermar	/trunk/uspace/	VFS work. Turn the dummy skeleton into a dummy skeleton that can handle connections. There are already traces of the VFS protocol.
