Since Jim is busy with other work and I'm working on some things that rely on this, I've taken up the task of doing the iterations. I've addressed the comments as best I can (those replies are to each individual change) and here is the patch set to go with those. I added my own signoff to each commit, but I've left jshargo@ as the author of all the commits he wrote. I'm sure there is still more to address and the ICT tests that were writtein parallel to this may also need some additions, but I'm hoping we're in a good enough state to get this in and iterate from there soon. Since V5: ======== Fixed some bad merge conflicts and locking behaviours as well as clarified some documentation, should be good to go now : Since V4: ======== Fixed up some documentation as suggested by Marius Fixed up some bad locking as suggested by Marius Small fixes here and there (most have email responses to previous chain emails) Since V3: ======== I've added hotplug support in the latest patch. This has been reviewed some and the notes from that review are addressed here as well. Relevant/Utilizing work: ======================= I've built a while test framework based on this as proof it functions (though I'm sure there may be lingering bugs!). You can check that out on crrev.com if you are interested and need to get started yourself (but be aware of any licensing that may differ from the kernel itself! Make sure you understand the license: https://source.chromium.org/chromiumos/chromiumos/codesearch/+/main:src/platform/tast-tests/LICENSE That said, you can see the changes in review on the crrev gerrit: https://chromium-review.googlesource.com/c/chromiumos/platform/tast-tests/+/4666669 Outro: ===== I really appreciate everyone's input and tolerance in getting these changes in. Jim's first patch series was this, and other than some small cleanups and documentation, taking over it is also mine.
