test: Convert fs_helper to use a class

2026-03-23T15:18:30+00:00

Create a class around mk_fs() (and later setup_image()) to handle the
common tasks of image creation. Many callers of fs_helper.mk_fs()
create their own scratch directories while users of
fs_helper.setup_image() rely on one being returned. Unify this by
adding 'srcdir' as a field while converting to a class.

The class delegates to the existing mk_fs() function for the actual
filesystem creation, adding lifecycle management for scratch
directories and the image file.

test: fs_helper: Drop the size_gran argument

2026-03-23T15:18:30+00:00

Nothing uses this argument, so make it a constant for now.

test: Update comment for fs_helper.setup_image()

2026-03-23T15:18:30+00:00

This function actually allows creating two partitions now, so update its
comment to match that.

test: fs_helper: Add a quiet flag to mk_fs()

2026-03-23T15:18:29+00:00

In many cases callers only want to see warnings and errors from the
filesystem-creation tools, not their normal output.

Add a quiet parameter to mk_fs() that suppresses the output of mkfs
and switches mcopy from verbose to quiet mode.

test: fs_helper: Allow passing the image filename

2026-03-23T15:18:29+00:00

The mk_fs() function always generates its own image filename from the
prefix and fs_type. Some callers need to specify a custom leaf name
while still keeping the image under the persistent-data directory.

Add an fs_img parameter that accepts a leaf filename. When provided,
it is joined with persistent_data_dir instead of the default name.

Merge patch series "Improve pytest runtime"

2025-04-08T19:54:50+00:00

Tom Rini  says:

One thing that Simon Glass has noted is that our pytest run time keeps
getting longer. Looking at:
https://source.denx.de/u-boot/u-boot/-/pipelines/25011/test_report?job_name=sandbox%20test.py%3A%20%5Bfast%20amd64%5D
we can see that some of the longest running tests are a little puzzling.
It turns out that we have two ways of making filesystem images without
requiring root access and one of them is significantly slower than the
other. This series changes us from using virt-make-fs to only using the
mk_fs helper that currently resides in test_ut.py which uses standard
userspace tools. The final result can be seen at:
https://source.denx.de/u-boot/u-boot/-/pipelines/25015/test_report?job_name=sandbox%20test.py%3A%20%5Bfast%20amd64%5D
and the tests changed here now run much quicker.

test/py: Fix a problem with setup_image

2025-04-08T19:51:09+00:00

While we can be passed an image size to use, we always called qemu-img
with 20M as the size. Fix this by using the size parameter.

test/py/tests: Move "setup_image" from test_ut.py to fs_helper.py

2025-04-08T19:51:09+00:00

The generic function in test_ut.py to create a disk image with partition
table can be useful outside of test_ut.py so move it to be available
more clearly.

To make this a bit more easily used library function, make use of
check_call directly rather than calling things though u_boot_utils. In
turn, to more easily handle stdin here, use the shell "printf" utility
to pass sfdisk the specification to create as we do not have an actual
file descriptor to use here.

Merge patch series "fs: exfat: Add exfat port based on exfat-fuse"

2025-04-03T02:01:14+00:00

Marek Vasut  says:

Import exfat-fuse libexfat, add U-Boot filesystem layer porting glue
code and wire exfat support into generic filesystem support code. This
adds exfat support to U-Boot.

Fill in generic filesystem interface for mkdir and rm commands.
Make filesystem tests test the generic interface as well as exfat,
to make sure this code does not fall apart.

test_fs: Add exfat tests

2025-04-03T02:00:59+00:00

Add tests for the exfat filesystem. These tests are largely an
extension of the FS_GENERIC tests with the following notable
exceptions.

The filesystem image for exfat tests is generated using combination
of exfatprogs mkfs.exfat and python fattools. The fattols are capable
of generating exfat filesystem images too, but this is not used, the
fattools are only used as a replacement for dosfstools 'mcopy' and
'mdir', which are used to insert files and directories into existing
fatfs images and list existing fatfs images respectively, without the
need for superuser access to mount such images.

The exfat filesystem has no filesystem specific command, there is only
the generic filesystem command interface, therefore check_ubconfig()
has to special case exfat and skip check for CONFIG_CMD_EXFAT and
instead check for CONFIG_FS_EXFAT.
