From 1ab4d3079d29e9ebee0c85f1aec14a3b1df8f679 Mon Sep 17 00:00:00 2001 From: Michael Brown Date: Wed, 13 Mar 2024 15:08:10 +0000 Subject: [mp] Define an API for multiprocessor functions Define an API for executing very limited functions on application processors in a multiprocessor system, along with an x86-only implementation. The normal iPXE runtime environment is effectively non-existent on application processors. There is no ability to make firmware calls (e.g. to write to a console), and there may be no stack space available.
