Hello there, Recent versions of gcc say this: include/drm/i915_drm.h:96:34: warning: result of ‘65535 << 20’ requires 37 bits to represent, but ‘int’ only has 32 bits [-Wshift-overflow=] Source code is #define INTEL_BSM_MASK (0xFFFF << 20) Maybe something like #define INTEL_BSM_MASK (0xFFFFUL<< 20) might be better. Regards David Binderman
