OpenPOWER Firmware Build Environment

Building an image

To build an image for a Palmetto system:

git clone --recursive [email protected]:open-power/op-build.git
cd op-build
. op-build-env
op-build palmetto_defconfig && op-build

There are also default configurations for other platforms in openpower/configs/. Current POWER8 platforms include Habanero, Firestone, and Garrison. Current POWER9 platforms include Witherspoon, Boston (p9dsu), Romulus, and Zaius.

Buildroot/op-build supports both native and cross-compilation - it will automatically download and build an appropriate toolchain as part of the build process, so you don't need to worry about setting up a cross-compiler. Cross-compiling from a x86-64 host is officially supported.

op-build's Issues

Some updates for Mihawk in upstream are really needed in op940

Currently we need some features to be merged or added in op940. Our due date is 12/10. We hope to have these updates as soon as possible.

1. skiboot update or backport to v6.5.x
   There are two commits we need:
   open-power/skiboot@52952ac
   open-power/skiboot@425340b
2. (Merged) kernel size reviewing
   op-build/PR/#664
3. (Merged) mihawk config merged
   op-build/PR/#658
   (This commit was merged upstream open-power/op-build@f9c0ed5)
4. (Merged) Petitboot updates for RHEL8/Openshift support [Nice-to-Have for GA1]
   Patches are now upstream:
   open-power/petitboot@057dce2
   (just mirror the @jk-ozlabs msg from internal commit/bugzillia)

Need Mihawk platform file in skiboot for op930 branch

Looks like the pull-request for Mihawk config files is merged and closed. ibm-op-release/op-build/(#592)

Now we need Mihawk platform file pick-up from upstream. open-power/skiboot@9570730

From ibm taipei AE's notice, it sounds like skiboot team will backport Mihawk related patches to skiboot-6.3.x branch. so we would like to create this issue to track the status. Since our release plan is on 8/5 and 8/19, we really need to catch up the schedule.
