[U-Boot] F2FS support

[Gerasimov, Anton]

Greetings,

Is anyone aware of any work in progress to support F2FS in U-Boot.
Search engines somehow don't give me anything relevant.

Thanks!

Best regards,
Anton Gerasimov

None that I'm aware of . Is F2FS worth supporting , compared to eg.
btrfs, which is used on eMMC by eg. jolla ?

I'm also not aware of any ongoing support work for F2FS.

You may want to look into some Samsung "open source" repositories, as
this FS origins from there.

Good question - I did not heard from anybody about such need.

IMHO it takes around 10years to make FS mature and production ready.

[U-Boot] F2FS support

[Gerasimov, Anton]

Hi Lukasz, hi Marek,

thank you for your feedbacks. I'm looking for a solution to improve the
resilience of our system against a sudden power loss under extensive
write load. Some tests [1] show that F2FS might be more robust than
ext4, so I wanted to give it a try. Not sure if it is really worth it,
there are opposite opinions as well.

Best,
Anton

Would btrfs work ?

BTRFS hasn't been too stable for me even on a desktop, so I didn't
consider that yet. But probably I will test it as well just to be objective.

Thanks,
Anton

It really depends on what features you use with btrfs. Some things can
be really problematic, see the btrfs wiki.

Which sort of storage device are you using?  I think results may
differ (a lot) even when doing the same thing on different storage
types.  Also, there is often a huge differnce between consumer (or
no-name) and industrial (or quality branded) products...  Even
within the same technology CompactFlash (who can remember that?),
SDCard and eMMC all use flash based storage, but they behave very
differently.

Best regards,

Wolfgang Denk

If you're not part of the solution, you're part of the problem.
