From 022906afdf90327bce33d52fb4fb41b6c7d618fb Mon Sep 17 00:00:00 2001 From: Simon Richter Simon.Richter@hogyros.de Date: Sat, 2 Aug 2025 11:40:36 +0900 Subject: [PATCH] Mark xe driver as BROKEN if kernel page size is not 4kB MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit
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.
