From f32d4ab41c467c0e4ddcaff37e4f2af57bcaad8c Mon Sep 17 00:00:00 2001 From: Nicholas Piggin Date: Fri, 18 Feb 2022 08:34:14 +0100 Subject: [PATCH] target/ppc: make vhyp get_pate method take lpid and return success MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit In prepartion for implementing a full partition table option for vhyp, update the get_pate method to take an lpid and return a success/fail indicator. The spapr implementation currently just asserts lpid is always 0 and always return success.
