7 Patches should be sent to dri-devel@lists.freedesktop.org, using git
8 send-email. For patches only touching driver specific code one of the driver
9 mailing lists (like amd-gfx@lists.freedesktop.org) is also appropriate. See git
10 documentation for help:
12 http://git-scm.com/documentation
14 Since dri-devel is a very busy mailing list please use --subject-prefix="PATCH
15 libdrm" to make it easier to find libdrm patches. This is best done by running
17 git config --local format.subjectprefix "PATCH libdrm"
19 The first line of a commit message should contain a prefix indicating what part
20 is affected by the patch followed by one sentence that describes the change. For
23 amdgpu: Use uint32_t i in amdgpu_find_bo_by_cpu_mapping
25 The body of the commit message should describe what the patch changes and why,
26 and also note any particular side effects. For a recommended reading on
27 writing commit messages, see:
29 http://who-t.blogspot.de/2009/12/on-commit-messages.html
31 Your patches should also include a Signed-off-by line with your name and email
32 address. If you're not the patch's original author, you should also gather
33 S-o-b's by them (and/or whomever gave the patch to you.) The significance of
34 this is that it certifies that you created the patch, that it was created under
35 an appropriate open source license, or provided to you under those terms. This
36 lets us indicate a chain of responsibility for the copyright status of the code.
39 https://developercertificate.org/
41 We won't reject patches that lack S-o-b, but it is strongly recommended.
46 Patches should have at least one positive review (Reviewed-by: tag) or
47 indication of approval (Acked-by: tag) before merging. For any code shared
48 between drivers this is mandatory.
50 Please note that kernel/userspace API header files have special rules, see
53 Coding style in the project loosely follows the CodingStyle of the linux kernel:
55 https://www.kernel.org/doc/html/latest/process/coding-style.html?highlight=coding%20style
60 Commit rights will be granted to anyone who requests them and fulfills the
63 - Submitted a few (5-10 as a rule of thumb) non-trivial (not just simple
64 spelling fixes and whitespace adjustment) patches that have been merged
65 already. Since libdrm is just a glue library between the kernel and userspace
66 drivers, merged patches to those components also count towards the commit
69 - Are actively participating on discussions about their work (on the mailing
70 list or IRC). This should not be interpreted as a requirement to review other
71 peoples patches but just make sure that patch submission isn't one-way
72 communication. Cross-review is still highly encouraged.
74 - Will be regularly contributing further patches. This includes regular
75 contributors to other parts of the open source graphics stack who only
76 do the oddball rare patch within libdrm itself.
78 - Agrees to use their commit rights in accordance with the documented merge
79 criteria, tools, and processes.
81 To apply for commit rights ("Developer" role in gitlab) send a mail to
82 dri-devel@lists.freedesktop.org and please ping the maintainers if your request
85 Committers are encouraged to request their commit rights get removed when they
86 no longer contribute to the project. Commit rights will be reinstated when they
87 come back to the project.
89 Maintainers and committers should encourage contributors to request commit
90 rights, as especially junior contributors tend to underestimate their skills.
95 Please be aware the fd.o Code of Conduct also applies to libdrm:
97 https://www.freedesktop.org/wiki/CodeOfConduct/
99 See the gitlab project owners for contact details of the libdrm maintainers.
101 Abuse of commit rights, like engaging in commit fights or willfully pushing
102 patches that violate the documented merge criteria, will also be handled through
103 the Code of Conduct enforcement process.
