With gcc-15, there is a new warning treated as error
As shown with gcc-15:
drivers/gpu/drm/i915/gvt/opregion.c: In function intel_vgpu_init_opregion:
drivers/gpu/drm/i915/gvt/opregion.c:35:28: error: initializer-string for
array of char is too long [-Werror=unterminated-string-initialization]
35 | #define OPREGION_SIGNATURE "IntelGraphicsMem"
| ^~~~~~~~~~~~~~~~~~
drivers/gpu/drm/i915/gvt/opregion.c:225:45: note: in expansion of macro
OPREGION_SIGNATURE
225 | const char opregion_signature[16] = OPREGION_SIGNATURE;
| ^~~~~~~~~~~~~~~~~~
cc1: all warnings being treated as errors
Rework the previous fix by reverting it, then two options:
- Enlarge the signature field
- Reduce the string size
I would use the latter, but I don't know the runtime implication of it
(hence the RFC).
This issue was discovered by building longterm kernel-6.12 in newer
fedora, See also:
