From cce84fc9193e2566b4f7f9de5a13e7ed360d44d9 Mon Sep 17 00:00:00 2001 From: Frederic Barrat Date: Thu, 1 Jun 2023 14:13:27 +0200 Subject: [PATCH] pnv/xive2: Add definition for TCTXT Config register MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add basic read/write support for the TCTXT Config register on P10. qemu doesn't do anything with it yet, but it avoids logging a guest error when skiboot configures the fused-core state: qemu-system-ppc64 -machine powernv10 ... -d guest_errors ...
