Commit Message

Ed Maste Dec. 8, 2024, 3:17 p.m. UTC
These two files (i915_live_selftests.h, i915_mock_selftests.h) were
introduced in commit 953c7f82eb89 ("drm/i915: Provide a hook for
selftests") and are effectively just a list of selftests.

The selftest implementation itself is largely in i915_selftest.c, and
uses a MIT license.  Graphics drivers are shared with other operating
systems and have long used a permissive license (or dual license) to
facilitate this.

The two selftest list files carried no license when introduced in
953c7f82eb89, presumably as they were considered trivial.  Notably the
general selftest header i915_selftest.h (which does have non-trivial
content) also has an MIT license.

The GPL-2.0 SPDX tag in these two files came from b24413180f56, where
Greg Kroah-Hartman added the tag to all files that had no license.  This
makes sense in general, but it is clear from the context of the original
selftest commit here that these files are a trivial part of an otherwise
MIT-licensed patch to a MIT-licensed component, and should have an MIT
license.

Chris, do you confirm your intention of MIT and not GPL for these files?

Cc: Greg KH <gregkh@linuxfoundation.org>

Greg, is this acceptable?

No, that is not clear, by default, anything without a license gets the
GPL2 license as that is the license of the entire body of code.

You need to get a signed-off-by from everyone who has touched these
files, which is not what you have done here :(

good luck!
