1.20170703-1 kernel packages

Thu Aug 03, 2017 8:13 pm

Does anyone know which git commit was used to build the kernel in the 1.20170703-1 version of raspberypi-kernel?

There are git tags corresponding to older builds of the kernel, but there's no tag for 1.20170703-1.

Aha, you're on to something there. The firmware git contains kernel builds, too. (Though, I'm going to look at the official one under github.com/raspberrypi/firmware)

Helpfully, there's a commit in firmware/ labelled "Bump to 4.9.35" (which is the version in 1.20170703-1). I compared the kernel7.img file from that commit with the one running on my Pi and they're the same. Even more helpfully, there's a file "extra/git_hash" which contains the commit (in github.com/raspberrypi/linux) used to build the kernel. Exactly what I was looking for!
