Recently, we merged into the op-build<\/a> project (the build scripts for OpenPOWER<\/a> Firmware) a defconfig for building OPAL for (certain) POWER9 simulators.

We’re using upstream Linux 4.7.0-rc3 and upstream skiboot (master), so all of this code is already <\/strong>upstream!<\/strong><\/p>\n

Now, by no means is this complete. There’s some fairly fundamental things that are missing (e.g. PCI) – but how many other platforms can you build open source <\/strong>firmware for before you can even get your hands on a simulator?<\/p>\n","protected":false},"excerpt":{"rendered":"
