From 041205cf7bc0fbda501e3609116559df45437545 Mon Sep 17 00:00:00 2001 From: Simon Richter Date: Mon, 18 Aug 2025 15:47:35 +0900 Subject: [PATCH] drm/xe: Make page size consistent in loop [ Upstream commit b85bb2d677153d990924d31be9416166d22382eb ] If PAGE_SIZE != XE_PAGE_SIZE (which is currently locked behind CONFIG_BROKEN), this would generate the wrong number of PDEs. Since these PDEs are consumed by the GPU, the GPU page size needs to be used.
