3022 5859 d 22 h decky /branches/dd/ device drivers branch  
2958 5870 d 11 h jermar /trunk/uspace/srv/ Make VFS_MOUNT call even when mounting the root file system.  
2957 5870 d 12 h jermar /trunk/uspace/srv/vfs/ Cram VFS_MOUNT into one message. This creates a hidden demand for the sixth IPC
argument as there might be a desire to pass some options/flags in the future.		  
2953 5871 d 12 h jermar /trunk/uspace/srv/fs/fat/ Add synchronization to fat_match().  
2951 5871 d 13 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.		  
2945 5872 d 11 h jermar /trunk/uspace/srv/fs/fat/ Introduce a futex protecting the up_hash and ui_hash.  
2944 5872 d 12 h jermar /trunk/uspace/srv/fs/fat/ Introduce futex for protecting the list of unused structures in FAT server.  
2910 5876 d 16 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 5877 d 21 h jermar /trunk/uspace/srv/fs/fat/ More bits of fat_node_get().
Still needs to do some locking.		  
2891 5880 d 11 h jermar /trunk/uspace/srv/fs/fat/ New first bits of fat_node_get().  
2890 5880 d 13 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.		  
2889 5883 d 12 h jermar /trunk/uspace/srv/fs/fat/ Add hash table for used fat_idx_t structures and implement fat_idx_map().  
2884 5884 d 12 h jermar /trunk/uspace/srv/fs/fat/ merge vs. coalesce  
2881 5884 d 16 h jermar /trunk/uspace/srv/fs/fat/ Code for de/allocation of VFS indices for FAT.  
2876 5884 d 20 h jermar /trunk/uspace/srv/fs/fat/ Add a dedicated source file for handling FAT indices.  
2864 5898 d 10 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 5898 d 21 h jermar /trunk/uspace/ Revert libfs node_get() API to a model without the parent node pointer
argument.		  
2859 5904 d 3 h jermar /trunk/uspace/srv/fs/fat/ Add fat_block_get().  
2858 5904 d 5 h jermar /trunk/uspace/ libfs destroy operation should rather return an error code instead of a truth
value.		  
2857 5904 d 6 h jermar /trunk/uspace/ Add stubs for unimplemented FAT libfs operations.  
2856 5904 d 6 h jermar /trunk/uspace/srv/fs/fat/ Add a locking scheme for FAT in-core cache and nodes.  
2855 5904 d 7 h jermar /trunk/uspace/srv/fs/fat/ fat_node_put(). No locking so far.  
2852 5905 d 3 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 5906 d 9 h jermar /trunk/uspace/srv/fs/fat/ Add fat_has_children(). Alse assume that fat_block_get() can never return NULL.  
2844 5906 d 10 h jermar /trunk/uspace/ Add fat_root_get() and fat_plb_get_char().  
2843 5906 d 11 h jermar /trunk/uspace/srv/fs/fat/ Somewhat complete implementation of fat_node_get().  
2831 5909 d 4 h jermar /trunk/uspace/ Commit progress on the FAT file system server implementation.  
2828 5910 d 8 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 5911 d 7 h jermar /trunk/uspace/srv/fs/fat/ Introduce and also use the foundation of block cache API in FAT's match
operation.		  
2821 5911 d 7 h jermar /trunk/uspace/srv/vfs/ Update comment.  
2798 5915 d 12 h jermar /trunk/uspace/ Replace all endian.h in uspace with a copy of the kernel's respective byteorder.h.  
2796 5916 d 12 h jermar /trunk/uspace/srv/fs/fat/ Convert FAT on-disk metadata from little-endian to native representation.  
2793 5916 d 13 h jermar /trunk/uspace/srv/fs/fat/ First untested bits of FAT lookup support.  
2792 5916 d 13 h jermar /trunk/uspace/ libfs' node_get() operation does not need the file system handle.  
2791 5919 d 10 h jermar /trunk/uspace/ Make libfs_lookup() more generic.  
2789 5922 d 0 h jermar /trunk/uspace/srv/fs/fat/ Fix FAT boot sector definition and introduce the FAT in-core node type.  
2788 5922 d 1 h jermar /trunk/uspace/ Return EBUSY if trying to mount something over an already mounted root FS.

2770 5938 d 12 h jermar /trunk/uspace/ Introduce fs_handle_t, dev_handle_t and fs_index_t.  
2769 5939 d 11 h jermar /trunk/uspace/srv/vfs/ VFS index needs to be treated as uint64_t.  
2768 5939 d 13 h jermar /trunk/uspace/srv/vfs/ Fibril serialization is required when two file systems register contemporarily.
