Hi Lukas,
I'm sorry I haven't reacted sooner. I've enabled the option to only
consider git send-email patches on intel-gfx as we were having a lot of
false positives (ie patchwork considering emails were people were making
suggestions with diffs as patches to test).
I'm not sure how you send your emails, but I can tell why that it didn't
pass the "is this a git send-email patch?" question. We're looking at
two things:
- The X-Mailer header
- The Message-Id (git send-email has a special way to craft its
message IDs)
I've replayed your email by hand with an extra X-Mailer header and
patchwork picked it up (and hopefully we should have a run of our basic
acceptance tests done on it):
https://patchwork.freedesktop.org/series/4068/
You can keep whatever you're doing now and trick patchwork to take your
patches by added this extra header to your emails:
X-Mailer: git-send-email 2.4.3
Or use git send-email.
HTH,
