2594 6049 d 2 h cejka /trunk/uspace/ New version of device mapper.
Added devmap test to tester.
 
2593 6050 d 3 h jermar /trunk/uspace/srv/vfs/ 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.
 
2592 6050 d 6 h jermar /trunk/uspace/lib/libc/include/ assert.h should include stdio.h  
2591 6050 d 6 h jermar /trunk/uspace/lib/libc/arch/ppc64/src/ Fix file included by ppc64's tls.c.  
2590 6051 d 6 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.
 
2589 6051 d 7 h jermar /trunk/uspace/srv/vfs/ 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.
 
2588 6051 d 8 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 6051 d 8 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.
 
2586 6055 d 0 h jermar /trunk/uspace/lib/libc/ Unify implementations of TLS variant I and variant II __alloc_tls() and
__free_tls_arch().
 
2583 6057 d 1 h jermar /trunk/uspace/lib/libc/arch/mips32/ Change BFD_NAME from elf32-little to elf32-tradlittlemips.  
2582 6057 d 2 h jermar /trunk/ Change BFD_TARGET from elf32-little to elf32-littlearm.  
2581 6057 d 2 h jermar /trunk/uspace/lib/libc/ For architectures that make use of TLS variant II (i.e. amd64, ia32 and
sparc64), fix the way TLS and TCB is allocated. Now, TLS is allocated using
memalign() with the alignment specified in _tls_alignment. Size of TLS data
itself is rounded up to be a multiple of _tls_alignment.
 
2580 6057 d 2 h jermar /trunk/uspace/lib/libc/arch/ In all architectures' uspace linker scripts, define the _tls_alignment symbol.  
2577 6059 d 2 h jermar /trunk/ Build system fixes.
Continue cleaning uspace even if cleanup of one component fails.
Remove main Makefile.config after boot, kernel and uspace are cleaned because
cleaning of these components might depend on variables set in the main
Makefile.config.
 
2576 6059 d 3 h jermar /trunk/uspace/srv/vfs/ Specify the width of the printed text in an argument to printf().  
2570 6081 d 8 h jermar /trunk/uspace/lib/libc/generic/io/ Fix a bug in interpretation of precision when printing strings. Fix cstyle.  
2569 6081 d 10 h jermar /trunk/uspace/ Tiny refinement of if-else_if-else statement in vfs_register.c.  
2568 6082 d 16 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.
 
2567 6082 d 16 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().
 
2566 6082 d 16 h jermar /trunk/uspace/srv/console/ Fix cstyle in console.c.  
2565 6082 d 16 h jermar /trunk/uspace/lib/libc/malloc/ Make uspace malloc() verbose when it aborts due to inconsistencies.  
2564 6082 d 16 h jermar /trunk/uspace/lib/libc/ Support for time() function.  
2560 6086 d 5 h jermar /trunk/uspace/srv/vfs/ VFS work.
Start VFS_OPEN.
 
2555 6087 d 0 h cejka /trunk/uspace/srv/devmap/ Added message forwarding to device mapper.  
2554 6087 d 1 h jermar /trunk/uspace/srv/vfs/ VFS work.
Add the missing bits of VFS-side VFS_MOUNT.
 
2553 6087 d 2 h jermar /trunk/uspace/srv/vfs/ VFS work.
Prevent race conditions when checking rootfs by taking a newly introduced
rootfs_futex.
 
2552 6087 d 3 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 6087 d 6 h cejka /trunk/ Fixed naming convention in IPC.  
2549 6087 d 8 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 6087 d 9 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.
 
2547 6087 d 9 h cejka /trunk/ Added basic support for device mapper.  
2546 6087 d 12 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 6088 d 5 h jermar /trunk/uspace/srv/vfs/ VFS work.
Proto implementation of VFS-side vfs_lookup_internal().
 
2543 6088 d 7 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 6088 d 10 h jermar /trunk/uspace/srv/vfs/ VFS work.
Start support for the Patch Lookup Buffer.
Also add rootfs pointer.
 
2541 6088 d 10 h jermar /trunk/uspace/ Header cleanup.
Move off_t, size_t and ssize_t into sys/types.h.
Get rid off the non-standard and dummy types.h.
 
2540 6089 d 1 h jermar /trunk/uspace/srv/vfs/ VFS work.
Introduce basic types representing a file system node and an open file.
 
2539 6089 d 7 h jermar /trunk/uspace/srv/console/ Cstyle and other minor fixes in the console code.  
2536 6093 d 3 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 6095 d 6 h jermar /trunk/uspace/srv/vfs/ Move VFS_REGISTER functionality into a separate file.
