jermar
/trunk/uspace/srv/fs/fat/
Introduce the foundation for unique and stable FAT VFS node indices.

the code to be aware of this.

argument.

libfs destroy operation should rather return an error code instead of a truth
value.

2844
6010 d 3 h
jermar

Add fat_root_get() and fat_plb_get_char().
2843
6010 d 4 h

Somewhat complete implementation of fat_node_get().
2831
6012 d 20 h

Commit progress on the FAT file system server implementation.
2828
6014 d 0 h
jermar
/trunk/uspace/srv/fs/fat/
BPS read from FAT bootsector is little-endian. It must converted to host
endianity before being used.
2822
6015 d 0 h
jermar
/trunk/uspace/srv/fs/fat/
Introduce and also use the foundation of block cache API in FAT's match
operation.
2798
6019 d 5 h
jermar
/trunk/uspace/
Replace all endian.h in uspace with a copy of the kernel's respective byteorder.h.
2796
6020 d 5 h
jermar
/trunk/uspace/srv/fs/fat/
Convert FAT on-disk metadata from little-endian to native representation.
2793
6020 d 6 h
jermar
/trunk/uspace/srv/fs/fat/
First untested bits of FAT lookup support.
2789
6025 d 17 h
jermar
/trunk/uspace/srv/fs/fat/
Fix FAT boot sector definition and introduce the FAT in-core node type.
2731
6065 d 12 h
jermar
/trunk/uspace/srv/
Add the VFS_FREE operation. This operation frees up whatever resources used by
a file system node for which there is no name (i.e. an unlinked node).
Cleanup VFS operations enums and remove unneeded VFS operations.
2690
6105 d 3 h
jermar
/trunk/uspace/srv/
Make a distinction between VFS operations that are common to VFS and FS
implementations, operations that are VFS only and operations that are FS
implementations only.
2644
6128 d 8 h
jermar
/trunk/uspace/
Move incomplete fs interface from fat.h to libfs.
2643
6128 d 9 h

VFS work.
Move FS registration code to libfs.
2639

FAT work.
Foundation for FAT dentry comparison function.
Beware of looking at the diff or risk loosing sanity.
2638

Sync IPC comments with IPC code.
2637

Extended IPC_M_CONNECT_TO_ME to use 3 user defined parameters.
Phone identifier is passed in ARG5.
2635
6142 d 5 h
cejka

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.

FAT work.
Start VFS_LOOKUP support in FAT.

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().
2615
6155 d 13 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.
2588
6171 d 10 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.
2568
6202 d 18 h
jermar
/trunk/uspace/
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.

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.

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.

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.
