2588 6047 d 20 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.
 
2587 6047 d 21 h jermar /trunk/uspace/srv/vfs/ 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.
 
2576 6055 d 16 h jermar /trunk/uspace/srv/vfs/ Specify the width of the printed text in an argument to printf().  
2569 6077 d 22 h jermar /trunk/uspace/ Tiny refinement of if-else_if-else statement in vfs_register.c.  
2567 6079 d 5 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().
 
2560 6082 d 17 h jermar /trunk/uspace/srv/vfs/ VFS work.
Start VFS_OPEN.
 
2554 6083 d 13 h jermar /trunk/uspace/srv/vfs/ VFS work.
Add the missing bits of VFS-side VFS_MOUNT.
 
2553 6083 d 15 h jermar /trunk/uspace/srv/vfs/ VFS work.
Prevent race conditions when checking rootfs by taking a newly introduced
rootfs_futex.
 
2552 6083 d 15 h jermar /trunk/uspace/srv/vfs/ VFS work.
This is a checkpoint commit.
It introduces initial, still incomplete, code for VFS-side VFS_MOUNT request.
 
2550 6083 d 19 h cejka /trunk/ Fixed naming convention in IPC.  
2549 6083 d 21 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 6083 d 22 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 6084 d 1 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.
 
2544 6084 d 17 h jermar /trunk/uspace/srv/vfs/ VFS work.
Proto implementation of VFS-side vfs_lookup_internal().
 
2543 6084 d 20 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.
 
2542 6084 d 23 h jermar /trunk/uspace/srv/vfs/ VFS work.
Start support for the Patch Lookup Buffer.
Also add rootfs pointer.
 
2540 6085 d 13 h jermar /trunk/uspace/srv/vfs/ VFS work.
Introduce basic types representing a file system node and an open file.
 
2536 6089 d 15 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 6091 d 18 h jermar /trunk/uspace/srv/vfs/ Move VFS_REGISTER functionality into a separate file.  
2532 6092 d 16 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.
