Kernel sources for corresponding rpi-update kernel release #225

Closed moodeaudio closed 4 years ago

moodeaudio commented 4 years ago

Hi,

How to determine which commit in the 5.4.y raspberry/linux source tree corresponds to a given rpi-update kernel release? For example which commit would be used to download the sources for the rpi-update 5.4.44 kernel?

In the 4.19 branch there used to be two commits after each rpi-update kernel release (example below) but these don't appear in the 5.4.y branch.

https://github.com/raspberrypi/linux/commits/rpi-4.19.y Merge remote-tracking branch 'stable/linux-4.19.y' into rpi-4.19.y Linux 4.19.126

The merge commits in 4.19 don't correspond with rpi-update releases. They are just the point where we have merged in latest stable tree. Use the git_hash file to find the commit in the raspberry/linux tree the release was built from. e.g.

$ cat /boot/.firmware_revision
65ab2e03576e6653bb45f5e68b80268a4401eecf

Then look at that revision of git_hash:

$ curl https://raw.githubusercontent.com/Hexxeh/rpi-firmware/65ab2e03576e6653bb45f5e68b80268a4401eecf/git_hash
3f54521ea7236a4e70dcb12ebc76ecafd54b8858

and use that to find source in the linux tree: https://github.com/raspberrypi/linux/tree/3f54521ea7236a4e70dcb12ebc76ecafd54b8858

Perfect, thanks :-)
