drm/xe: Fix wa_oob codegen recipe for external module builds

2026-06-16T17:18:43+00:00

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).

drm/xe/ras: Introduce correctable error handling

2026-04-30T06:01:45+00:00

Add initial support for correctable error handling which is serviced using system controller event. Currently we only log the errors in dmesg but this serves as a foundation for RAS infrastructure and will be further extended to facilitate other RAS features.

drm/i915/mchbar: Provide intel_mchbar_read*() abstraction

2026-04-01T14:02:36+00:00

MCHBAR registers are a bit special in that: - we access them through the mirror - the mirror is read only on HSW+ - the mirror requires the actual MCHBAR to be enabled in device 0:0.0 - the mirror is gone on MTL+ So I'd prefer to treat MCHBAR registers as a bit special in the code as well, and do all accesses to them via dedicated functions. Prodive such functions in the form of intel_mchbar_read*(). v2: Put the function arguments on one line No intel_uncore_read64() on xe, use intel_uncore_read64_2x32() Name the new function intel_mchbar_read64_2x32() as well Reviewed-by: Jani Nikula Signed-off-by: Ville Syrjälä Link: https://patch.msgid.link/20260331154259.24600-3-ville.syrjala@linux.intel.com

drm/{i915, xe}: convert VLV sideband display wrappers into real functions

Convert the VLV sideband static inline wrappers into real functions. This will help the follow-up work of moving the VLV sideband to the display parent interface. The downside is that we'll have to build vlv_sideband.c as part of xe build, to avoid a plethora of stubs.
