From 8b50ce850538223b8dd2c2f4ed8a819d3c60bfc1 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?C=C3=A9dric=20Le=20Goater?= Date: Thu, 5 Dec 2019 19:44:53 +0100 Subject: [PATCH] ppc/pnv: add a PSI bridge model for POWER10 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The POWER10 PSIHB controller is very similar to the one on POWER9. We should probably introduce a common PnvPsiXive object. The ESB page size should be changed to 64k when P10 support is ready.
