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. |

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. |

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. |

VFS work.
Increment reference counters for the VFS nodes representing the mount point and
the root of the mounted filesystem, respectively, during VFS_MOUNT. Take the
unlink_futex when transforming the triplet into a VFS node. |

A lot of more VFS prototyping.
VFS_OPEN gets reasonably complete, fix a limitation that prevented file
structures from being shared by multiple file descriptors, add functions for
file descriptor management, introduce unlink_futex and two new VFS operations
VFS_UNLINK and VFS_RENAME. |

VFS work.
Allocate the open filess array dynamically and protect access to it via a
per-connection futex. Defer its allocation until the client makes a first
VFS_OPEN request.
Actually call vfs_mount() and vfs_open(), respectively, when the VFS_MOUNT and
VFS_OPEN requests, respectively, are received from the client. |

write zero arguments all the time. |

VFS work.
Introduce the notion of VFS_PAIR which corresponds to a file system instance,
and VFS_TRIPLET, which corresponds to a file system node. Separate vfs_triplet_t
and vfs_node_t as the former one is the stateless counterpart of the latter. |

Rename fibril_schedule_next_adv() to fibril_switch(). Rename
fibril_schedule_next() to fibril_yield(). Some fibril structures could be
uninitialized, set them to zero in fibril_setup(). For some fibrils, the stack
member can be NULL (e.g. every thread's first/main fibril); don't do free on
these stacks when cleaning up after a dead fibril. |

Don't explicitly answer the IPC_M_DATA_SEND call in VFS_REGISTER.

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. |

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. |

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. |

Lookup Buffer in read-only mode. |

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. |
|

/trunk/uspace/ |
In async_new_connection(), be more robust in the case that the function
is called by the server directly after its client accepts the
IPC_M_CONNECT_TO_ME call.
In fat.c main(), kill the "main" fibril and switch to the connection
fibril. |
|
| 2533 |
6111 d 12 h |
jermar |
/trunk/uspace/srv/fs/fat/ |
No need to call async_manager() at the end of fat.c's main(). |

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. |

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(). |

Turn the empty fs service into the beginning of FAT support.
Start implementing the VFS protocol for fat.c. |
