From e7c689a249ca6b8d14a077bb0f3311eaeda2ca19 Mon Sep 17 00:00:00 2001 From: Roger Pau Monne Date: Fri, 29 Aug 2025 09:43:38 +0200 Subject: [PATCH] x86/pvshim: disable PDX compression in PV shim defconfig MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit There's no need for PDX compression given the memory map provided by Xen to guests is contiguous, turn off the feature by default in the PV shim defconfig.
