3593 5662 d 23 h rimsky /branches/sparc/ Merged latest trunk changes into sparc branch.  
3397 5729 d 8 h rimsky /branches/sparc/ Merged recent changes from trunk into the Sparc branch.  
3343 5753 d 5 h decky /branches/sparc/ add sparc branch  
3335 5754 d 1 h jermar /trunk/uspace/srv/fs/fat/ Support for readdir() on FAT.  
3325 5757 d 2 h jermar /trunk/uspace/srv/fs/fat/ Determine the size of a directory node by walking the FAT and counting clusters.
This eliminates the hardcoded limit on the number of directory entries.		  
3314 5758 d 3 h jermar /trunk/uspace/srv/fs/fat/ fat_read() should expect IPC_M_DATA_READ instead of IPC_M_DATA_WRITE.  
3312 5758 d 3 h jermar /trunk/uspace/srv/fs/fat/ When removing a FAT node from the ffn list, use the correct pointer instead of
an uninitialized one.		  
3308 5760 d 1 h jermar /trunk/uspace/srv/fs/fat/ More complete fat_read().  
3307 5760 d 3 h jermar /trunk/uspace/srv/fs/fat/ Dummy implementation of fat_read().  
3282 5762 d 0 h jermar /trunk/uspace/srv/fs/fat/ FAT dentry type used for subdirectories doesn't store the directory size in the 'size' field.
Introduce a simple workaround that will let us have 64 directory entries at maximum.		  
3272 5762 d 13 h jermar /trunk/uspace/srv/fs/fat/ Several fixes for the FAT file system:
- do not copy padding during file name canonization
- properly nul-terminate the FAT file name during canonization
- compare FAT file name and the component name case insensitively
- block_get() takes a block offset, not byte offset as parameter		  
3257 5763 d 12 h jermar /trunk/uspace/srv/fs/fat/ First attempt at delivering the FAT16 read-only support.
Needless to say it doesn't work yet, but now it's only
the lurking bugs that need to be fixed.		  
3253 5765 d 0 h jermar /trunk/uspace/srv/fs/fat/ Pass block size to block_get() in the last argument.  
3119 5826 d 7 h jermar /trunk/uspace/srv/fs/fat/ Initialize in-core FAT root directory node during mount.  
3110 5827 d 2 h jermar /trunk/uspace/srv/fs/fat/ Initialize global FAT IDX structures when the FAT server starts and initialize
per-file system FAT IDX structures when a file system gets mounted.		  
2953 5847 d 1 h jermar /trunk/uspace/srv/fs/fat/ Add synchronization to fat_match().  
2951 5847 d 2 h jermar /trunk/uspace/srv/fs/fat/ Add locks to FAT index structures, FAT in-core node structures. Add futex to
protect the list of free cached FAT in-core nodes. Make fat_node_get() and
fat_node_put() and some other functions aware of these new locks.		  
2910 5852 d 6 h jermar /trunk/uspace/srv/fs/fat/ Implement fat_node_put() and remove the node from the free node list when
bumping its refernce count from zero in fat_node_get().		  
2893 5853 d 11 h jermar /trunk/uspace/srv/fs/fat/ More bits of fat_node_get().
Still needs to do some locking.		  
2891 5856 d 1 h jermar /trunk/uspace/srv/fs/fat/ New first bits of fat_node_get().  
2890 5856 d 3 h jermar /trunk/uspace/srv/fs/fat/ Need a way to locate the FAT index structure by VFS index. Also fix code that
locates the FAT index structure by position in the file system namespace.		  
2881 5860 d 6 h jermar /trunk/uspace/srv/fs/fat/ Code for de/allocation of VFS indices for FAT.  
2876 5860 d 9 h jermar /trunk/uspace/srv/fs/fat/ Add a dedicated source file for handling FAT indices.  
2864 5873 d 23 h jermar /trunk/uspace/srv/fs/fat/ Introduce the foundation for unique and stable FAT VFS node indices.

The first two reserved FAT entries are physically present in each FAT, so fix
the code to be aware of this.		  
2863 5874 d 11 h jermar /trunk/uspace/ Revert libfs node_get() API to a model without the parent node pointer
argument.		  
2859 5879 d 16 h jermar /trunk/uspace/srv/fs/fat/ Add fat_block_get().  
2858 5879 d 19 h jermar /trunk/uspace/ libfs destroy operation should rather return an error code instead of a truth
value.		  
2857 5879 d 19 h jermar /trunk/uspace/ Add stubs for unimplemented FAT libfs operations.  
2856 5879 d 19 h jermar /trunk/uspace/srv/fs/fat/ Add a locking scheme for FAT in-core cache and nodes.  
2855 5879 d 20 h jermar /trunk/uspace/srv/fs/fat/ fat_node_put(). No locking so far.  
2852 5880 d 17 h jermar /trunk/uspace/ Add node_put() to libfs operations and instrument libfs_lookup() to use it at
appropriate places.
Add node_put() to libfs operations and instrument libfs_lookup() to use it at
appropriate places.
Add node_put() to libfs operations and instrument libfs_lookup() to use it at
appropriate places.
Add node_put() to libfs operations and instrument libfs_lookup() to use it at
appropriate places.
Add node_put() to libfs operations and instrument libfs_lookup() to use it at
appropriate places.
Add node_put() to libfs operations and instrument libfs_lookup() to use it at
appropriate places.		  
2845 5881 d 23 h jermar /trunk/uspace/srv/fs/fat/ Add fat_has_children(). Alse assume that fat_block_get() can never return NULL.  
2844 5881 d 23 h jermar /trunk/uspace/ Add fat_root_get() and fat_plb_get_char().  
2843 5882 d 0 h jermar /trunk/uspace/srv/fs/fat/ Somewhat complete implementation of fat_node_get().  
2831 5884 d 17 h jermar /trunk/uspace/ Commit progress on the FAT file system server implementation.  
2828 5885 d 21 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 5886 d 21 h jermar /trunk/uspace/srv/fs/fat/ Introduce and also use the foundation of block cache API in FAT's match
operation.		  
2798 5891 d 1 h jermar /trunk/uspace/ Replace all endian.h in uspace with a copy of the kernel's respective byteorder.h.  
2796 5892 d 1 h jermar /trunk/uspace/srv/fs/fat/ Convert FAT on-disk metadata from little-endian to native representation.  
2793 5892 d 2 h jermar /trunk/uspace/srv/fs/fat/ First untested bits of FAT lookup support.
