+dtu, will we be able to bisect once it's possible to bisect with a patch?

Yes, I think that's possible.

Kicked off a few more bisects with https://chromium-review.googlesource.com/c/chromium/src/+/922581 pinned now that this is possible on pinpoint.

dtu: This broke because pinned CL only works for the entire bisect, not a partial bisect, right? Is that planned?

The builds show this error message:

MBErr: Builder name "Android Compile Perf"  not found under masters[tryserver.chromium.perf] in "/b/c/b/Android_Compile_Perf/src/tools/mb/mb_config.pyl"

So this failed because the builder names changed. We would need to patch in the builder config changes as well. But we don't support multiple patches. (issue 820653)

THis can't be bisected.
