3022 5907 d 21 h decky /branches/dd/ device drivers branch  
3007 5910 d 13 h jermar /trunk/ Improve linking and loading of boot ELF images.
(Contributed by Jiri Svoboda)		  
3003 5911 d 12 h jermar /trunk/uspace/lib/libfs/ More of the preivous commit.  
3002 5911 d 12 h jermar /trunk/uspace/lib/libfs/ Optimize conditions in libfs_lookup(). Perform primitive comparisons in the
left-hand subexpression and potentially expensive calls to libfs operations in
the right-hand subexpression.		  
2958 5918 d 10 h jermar /trunk/uspace/srv/ Make VFS_MOUNT call even when mounting the root file system.  
2957 5918 d 11 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 5919 d 11 h jermar /trunk/uspace/srv/fs/fat/ Add synchronization to fat_match().  
2951 5919 d 11 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 5920 d 10 h jermar /trunk/uspace/srv/fs/fat/ Introduce a futex protecting the up_hash and ui_hash.  
2944 5920 d 11 h jermar /trunk/uspace/srv/fs/fat/ Introduce futex for protecting the list of unused structures in FAT server.  
2934 5921 d 13 h jermar /trunk/ Do not attempt to malloc() zero bytes of memory during VFS_READ at end of file.  
2910 5924 d 15 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 5925 d 20 h jermar /trunk/uspace/srv/fs/fat/ More bits of fat_node_get().
Still needs to do some locking.		  
2891 5928 d 10 h jermar /trunk/uspace/srv/fs/fat/ New first bits of fat_node_get().  
2890 5928 d 12 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 5931 d 11 h jermar /trunk/uspace/srv/fs/fat/ Add hash table for used fat_idx_t structures and implement fat_idx_map().  
2884 5932 d 11 h jermar /trunk/uspace/srv/fs/fat/ merge vs. coalesce  
2881 5932 d 15 h jermar /trunk/uspace/srv/fs/fat/ Code for de/allocation of VFS indices for FAT.  
2879 5932 d 16 h jermar /trunk/uspace/lib/libc/include/libadt/ Add functions for inserting items before or after other items in a boubly-linked
circular lists.		  
2876 5932 d 19 h jermar /trunk/uspace/srv/fs/fat/ Add a dedicated source file for handling FAT indices.  
2864 5946 d 9 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 5946 d 20 h jermar /trunk/uspace/ Revert libfs node_get() API to a model without the parent node pointer
argument.		  
2861 5950 d 12 h cejka /trunk/ Used common macro for context saving on ppc64.  
2860 5951 d 12 h cejka /trunk/ Context handling unified for sparc64.  
2859 5952 d 2 h jermar /trunk/uspace/srv/fs/fat/ Add fat_block_get().  
2858 5952 d 4 h jermar /trunk/uspace/ libfs destroy operation should rather return an error code instead of a truth
value.		  
2857 5952 d 5 h jermar /trunk/uspace/ Add stubs for unimplemented FAT libfs operations.  
2856 5952 d 5 h jermar /trunk/uspace/srv/fs/fat/ Add a locking scheme for FAT in-core cache and nodes.  
2855 5952 d 6 h jermar /trunk/uspace/srv/fs/fat/ fat_node_put(). No locking so far.  
2852 5953 d 2 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.

appropriate places.

appropriate places.

appropriate places.
Add node_put() to libfs operations and instrument libfs_lookup() to use it at
appropriate places.		  
2847 5954 d 5 h jermar /trunk/uspace/lib/libfs/ Reset the component length variable only prior collecting a new component.  
2846 5954 d 5 h jermar /trunk/uspace/lib/libfs/ Improve libfs_lookup() so that has_children() is not called for each character
in the pathname component.		  
2845 5954 d 8 h jermar /trunk/uspace/srv/fs/fat/ Add fat_has_children(). Alse assume that fat_block_get() can never return NULL.  
2844 5954 d 9 h jermar /trunk/uspace/ Add fat_root_get() and fat_plb_get_char().  
2843 5954 d 10 h jermar /trunk/uspace/srv/fs/fat/ Somewhat complete implementation of fat_node_get().  
2831 5957 d 3 h jermar /trunk/uspace/ Commit progress on the FAT file system server implementation.  
2830 5957 d 15 h jermar /trunk/ Add (c) and the modified BSD license to the config system.  
2828 5958 d 7 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 5959 d 6 h jermar /trunk/uspace/srv/fs/fat/ Introduce and also use the foundation of block cache API in FAT's match
operation.		  
2821 5959 d 6 h jermar /trunk/uspace/srv/vfs/ Update comment.
