This is the living area and distribution channel for SOF firmware and topology binaries. It's still very much WiP and may churn a little until things settle down.

This repo will be frequently rebased in order to keep the size small and is intended for packagers, release engineers, testers and devlopers.

The intention is to store all pre-compiled (and signed if neccesary) firmware binaries and pre-compiled topologies for snapshot, stable and LTS releases.

There are four types of SOF releases.

1. stable - fully validated release with updates for 6 months. Deleted 3 months after updates end.

2. LTS - fully validated release with updates for 2 years. Deleted 3 months after updates end.

3. nightly - unvalidated (may not even boot) high frequency release. Deleted immediately upon release of next nightly. Signed with public key if necessary.

4. snapshot vendor - unvalidated (may not even boot) high frequency release. Deleted immediately upon release of next vendor snapshot. Signed with vendor key - less frequent than nightly.

The repository will have a branch for each release e.g. latest vendor snapshots, nightlies and stable releases.

master ----+---> v1.4.2
           |
           +---> v1.5.4
           |
           +---> v1.6.1
           |
           +---> v18032020-intel
           |
           +---> v02032020
           |
           +---> lts-20.10

The master branch will not contain any binaries, but will contain all the tools necessary for release management.

It's possible due to release cadence to have several stable branches in the repository.

The nightly nightly snapshot branch will have a date tag vDDMMYYYY. The same date tag format will be used by vendor snapshots too.

Probably you need to clone a specific branch instead of cloning the default master branch. For example, to clone a stable branch, you can do:

git clone -b stable-v1.4.2 https://github.com/thesofproject/sof-bin.git

After that, change to the created directory and execute the script:

sudo ./go.sh

Each release currently takes up about 7MB and would quickly fill up and slow down the repository with old data. Therefore SOF stable releases will be also available on github whilst nightly and snapshot releases may be available on vendor servers (in line with any vendor build/signing cadence). Old relese branches will be deleted.
