Can you share a git branch with this patch? From memory these binary
patches don't apply well from emails.

Indeed. These patches are good candidate to use the 'git-format-patch
--no-binary' option with a link to a git repository to fetch the full

Some other project mailing lists do not prevent binary patch mails. If
this is QEMU convention, I suggest we document this in

This is not a convention, but a personal suggestion. QEMU mailing list don't have this limitation AFAIK. However some MTA do weird things when relaying encoded binaries, and the result is patch are simply not applicable.
Also such large (broken) mails are a pain when your mailbox has quota.

I added this entry:

      Do not output contents of changes in binary files,
      instead display a notice that those files changed.
      Patches generated using this option cannot be applied
      properly, but they are still useful for code review.

Sure. Please grab the bits from http://github.com/lbmeng/qemu opensbi branch.

You can also use patchwork to help with your custodian work.

Click on the "mbox" button to download the patch and apply it.

Will this be 5.0, or 5.1?

Unlikely 5.1, too late.

I am fine. Just wanted to know the strategy of which QEMU release to
ship which OpenSBI release. +Anup in case he has some comments.

Well I'm not taking any decision here, I'm simply sharing the impression I have after reading the thread between Palmer and Peter:
You can still ask Alistair to insist to Peter, but you'd need a strong reason :)
