ext4: implement exists() for ext4fs

2014-02-19T14:47:34+00:00

This hooks into the generic "file exists" support added in an earlier
patch, and provides an implementation for the ext4 filesystem.

Fix ext2/ext4 filesystem accesses beyond 2TiB

2013-07-15T21:06:13+00:00

With CONFIG_SYS_64BIT_LBA, lbaint_t gets defined as a 64-bit type,
which is required to represent block numbers for storage devices that
exceed 2TiB (the block size usually is 512B), e.g. recent hard drives

We now use lbaint_t for partition offset to reflect the lbaint_t change,
and access partitions beyond or crossing the 2.1TiB limit.
This required changes to signature of ext4fs_devread(), and type of all
variables relatives to block sector.

ext2/ext4 fs uses logical block represented by a 32 bit value. Logical
block is a multiple of device block sector. To avoid overflow problem
when calling ext4fs_devread(), we need to cast the sector parameter.

fs/ext4: Support device block sizes != 512 bytes

2013-05-10T12:16:33+00:00

The 512 byte block size was hard coded in the ext4 file systems.
Large harddisks today support bigger block sizes typically 4096
bytes.
This patch removes this limitation.

fs: Move ls and read methods into ext4, fat

2013-03-04T19:19:56+00:00

It doesn't make a lot of sense to have these methods in fs.c. They are
filesystem-specific, not generic code. Add each to the relevant
filesystem and remove the associated #ifdefs in fs.c.

fs: separate CONFIG_FS_{FAT, EXT4} from CONFIG_CMD_{FAT, EXT*}

2012-10-29T21:21:19+00:00

This makes the FAT and ext4 filesystem implementations build if
CONFIG_FS_{FAT,EXT4} are defined, rather than basing the build on
whether CONFIG_CMD_{FAT,EXT*} are defined. This will allow the
filesystems to be built separately from the filesystem-specific commands
that use them. This paves the way for the creation of filesystem-generic
commands that used the filesystems, without requiring the filesystem-
specific commands.

Minor documentation changes are made for this change.

The new config options are automatically selected by the old config
options to retain backwards-compatibility.

ext4: Rename block group descriptor table from gd to bgd

2012-10-04T01:21:33+00:00

On x86 machines gd is unfortunately a #define, so we should avoid using
gd for anything. This patch changes uses of gd to bgd so that ext4fs
can be used on x86.

A better fix would be to remove the #define in x86, but I'm not sure
how to do that.

cmd_extX: use common get_device_and_partition function

2012-09-25T21:46:55+00:00

Convert ext2/4 load, ls, and write functions to use common device and
partition parsing function. With the common function "dev:part" can come
from the environment and a '-' can be used in that case.

ext4: remove init_fs/deinit_fs

2012-09-25T21:46:35+00:00

There's no real need to expose this and it can be removed by using a static
allocation.
