From ec22f927327d160c76f85b7aa3bee94f1f793963 Mon Sep 17 00:00:00 2001 From: Simon Richter Date: Fri, 22 Aug 2025 16:30:36 -0400 Subject: [PATCH] Mark xe driver as BROKEN if kernel page size is not 4kB MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit [ Upstream commit 022906afdf90327bce33d52fb4fb41b6c7d618fb ] This driver, for the time being, assumes that the kernel page size is 4kB, so it fails on loong64 and aarch64 with 16kB pages, and ppc64el with 64kB pages.
