2563 6090 d 16 h vana /trunk/ Support for new gcc 4.2.1 on IA64  
2562 6090 d 16 h vana /trunk/boot/arch/ia64/loader/ IA64: Force gcc to build position dependend code (not to use gp register to count global data adresses). Because PIC code should adress only 2M of data.  
2561 6090 d 16 h vana /trunk/boot/arch/ia64/loader/ Fix section selection notation  
2560 6091 d 6 h jermar /trunk/uspace/srv/vfs/ VFS work.
Start VFS_OPEN.
 
2559 6091 d 9 h vana /trunk/boot/arch/ia64/loader/ Fill loader stack not to be used by linker to store data  
2558 6091 d 9 h vana /trunk/boot/arch/ia64/loader/ Rename section bss in loader to .bss to be correct linked  
2557 6091 d 12 h jermar /trunk/kernel/generic/src/ipc/ Enable forwarding of IPC_M_AS_AREA_SEND, IPC_M_AS_AREA_RECV, IPC_M_DATA_SEND
calls. In order to prevent the forwarder from cloberring the call data (i.e.
source and destination address, and size) by treating these three methods as
immutable on forward. This feature is experimental, but has huge benefits in
that it can significantly reduce the amount of data sharing (the middle man need
not modify its address space mappings) or the amount of data copying (the middle
man need not receive the data from the sender and then resend them to the next
recipient). As a result, it can reduce N such calls for a communication channel
with N tasks along the way to 1 such call.
 
2556 6091 d 14 h jermar /trunk/kernel/generic/ Rename as_get_size() to as_area_get_size() and add a doxygen comment.  
2555 6092 d 1 h cejka /trunk/uspace/srv/devmap/ Added message forwarding to device mapper.  
2554 6092 d 2 h jermar /trunk/uspace/srv/vfs/ VFS work.
Add the missing bits of VFS-side VFS_MOUNT.
 
2553 6092 d 4 h jermar /trunk/uspace/srv/vfs/ VFS work.
Prevent race conditions when checking rootfs by taking a newly introduced
rootfs_futex.
 
2552 6092 d 4 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.
 
2551 6092 d 7 h cejka /trunk/ DevMap, VFS and FAT added to boot images for all architectures.  
2550 6092 d 8 h cejka /trunk/ Fixed naming convention in IPC.  
2549 6092 d 10 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 6092 d 11 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 6092 d 11 h cejka /trunk/ Added basic support for device mapper.  
2546 6092 d 14 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.
 
2545 6092 d 15 h cejka /trunk/contrib/conf/ Added processor type into gxemul run script.  
2544 6093 d 6 h jermar /trunk/uspace/srv/vfs/ VFS work.
Proto implementation of VFS-side vfs_lookup_internal().
 
2543 6093 d 9 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 6093 d 12 h jermar /trunk/uspace/srv/vfs/ VFS work.
Start support for the Patch Lookup Buffer.
Also add rootfs pointer.
 
2541 6093 d 12 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 6094 d 2 h jermar /trunk/uspace/srv/vfs/ VFS work.
Introduce basic types representing a file system node and an open file.
 
2539 6094 d 9 h jermar /trunk/uspace/srv/console/ Cstyle and other minor fixes in the console code.  
2538 6096 d 14 h vana /trunk/kernel/arch/ia64/include/drivers/ Macro naming correction  
2537 6096 d 14 h vana /trunk/kernel/arch/ia64/include/drivers/ IA64 keyboard lost headerfile  
2536 6098 d 4 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 6100 d 8 h jermar /trunk/uspace/srv/vfs/ Move VFS_REGISTER functionality into a separate file.  
2534 6100 d 8 h jermar /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 6101 d 4 h jermar /trunk/uspace/srv/fs/fat/ No need to call async_manager() at the end of fat.c's main().  
2532 6101 d 6 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 6102 d 5 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().
 
2530 6102 d 19 h jermar /trunk/uspace/lib/libc/generic/ Pseudo thread -> fibril change in several comments.  
2529 6103 d 7 h jermar /trunk/uspace/ Turn the empty fs service into the beginning of FAT support.
Start implementing the VFS protocol for fat.c.
 
2528 6103 d 7 h jermar /trunk/uspace/lib/libc/ Modify parts of the build system and libc to support building applications on
paths with differing distances from lib/libc (e.g. uspace/srv/ns and
uspace/srv/fs/fat).
 
2527 6104 d 14 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 6105 d 10 h jermar /trunk/uspace/ VFS work.
Delve deeper into VFS_REGISTER.
 
2525 6105 d 11 h jermar /trunk/uspace/lib/libc/include/ Implementation of isalnum().  
2524 6105 d 11 h jermar /trunk/uspace/lib/libc/include/ Implementation of isalpha().
