Just to make it clear: did we test this on actual machines before
submitting or are we entirely relying on the CI results?
I'm not sure the CI is running enough tests to validate this patch with
confidence, we'll probably need to do some manual testing here.
At some point I believe it was agreed that CI would test this
and get the new firmware automatically from the cover-letter.
The problem is that I don't see any cover-letter so I'm afraid
it is not running with the new firmware.
Tomi?
The requests can be checked from patchwork REST API:
https://patchwork.freedesktop.org/api/1.0/projects/intel-gfx/events/?page=1&name=pull-request-new
There has been a pull request for new firmware, but it couldn't be
acted. CI can't connect to SSH repository, because those generally need
an account. This has been tried and tested before. Better way is to use
git://, http:// or https:// URLs, as the pull shouldn't need any special
permissions.
This time I have manually pulled
git://anongit.freedesktop.org/drm/drm-firmware/master but, if you want
to make this automatic, the pull requests shouldn't be from repositories
with obligatory login.
Another note: known firmware pull repositories are now
freedesktop.org git://anongit.freedesktop.org/drm/drm-firmware (fetch)
g_anushasr git://github.com/anushasr/linux-firmware.git (fetch)
h_anushasr https://github.com/anushasr/linux-firmware.git (fetch)
kernel.org
git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware
(fetch)
If you know that in future there might be pull requests from another
repository, please inform me about that in advance.
Tomi
Also I believe in case it has the cover letter it should run
the full CI on the machine or at least stash it and run on
the weekend or whenever we run the full on all machines and
then report back again. Possible?
Martin?
