From 92dc59ab2a09097cdf249e0288ff9b69261761c6 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Thomas=20Hellstr=C3=B6m?= Date: Thu, 4 Jun 2026 09:45:00 +0200 Subject: [PATCH] drm/xe: Fix wa_oob codegen recipe for external module builds MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When building with 'make M=drivers/gpu/drm/xe modules', kbuild invokes scripts/Makefile.build with obj=., causing $(obj) to expand to '.'. Make normalizes './xe_gen_wa_oob' to 'xe_gen_wa_oob' when constructing the $^ automatic variable (target name normalization), so the recipe command becomes just 'xe_gen_wa_oob ...' without any path prefix, and the shell cannot find the tool. Fix by replacing $^ with explicit $(obj)/xe_gen_wa_oob and $(src)/ references in both wa_oob recipe commands. In recipe strings, make does not apply target name normalization, so $(obj)/xe_gen_wa_oob correctly expands to './xe_gen_wa_oob' and the shell can execute it. This matches the pattern already used by other DRM drivers (e.g. radeon's mkregtable).
