This change updates runtime.semasleep to no longer call runtime.nanotime and instead calls lwp_park with a duration to sleep relative to the monotonic clock, so the nanotime is never called. (This requires updating to a newer version of the lwp_park system call, which is safe, because Go 1.10 will require the unreleased NetBSD 8+ anyway) Additionally, this change makes the nanotime function use the monotonic clock for netbsd/arm, which was forgotten from https://golang.org/cl/81135 which updated netbsd/amd64 and netbsd/386. Because semasleep previously depended on nanotime, the past few days of netbsd have likely been unstable because lwp_park was then mixing the monotonic and wall clocks. After this CL, lwp_park no longer depends on nanotime.

(Brad migrated the patch to Gerrit and checked CLAs) Updates #6007 Fixes #22968 Also updates netbsd/arm to use monotonic time for Change-Id: If77ef7dc610b3025831d84cdfadfbbba2c52acb2 Reviewed-on: https://go-review.googlesource.com/81715 Run-TryBot: Brad Fitzpatrick <bradfitz@golang.org> TryBot-Result: Gobot Gobot <gobot@golang.org> Reviewed-by: Brad Fitzpatrick <bradfitz@golang.org> |
