Note that nvidia/nv-interface.o is created, but not used by any modules.
In the kbuild we have:
#
# Build nv-interface.o from the kernel interface layer objects, suitable
# for further processing by the top-level makefile to produce a precompiled
# kernel interface file.
#
NVIDIA_INTERFACE := nvidia/nv-interface.o
# Linux kernel v5.12 and later looks at "always-y", Linux kernel versions
# before v5.6 looks at "always"; kernel versions between v5.12 and v5.6
# look at both.
always += $(NVIDIA_INTERFACE)
always-y += $(NVIDIA_INTERFACE)
$(obj)/$(NVIDIA_INTERFACE): $(addprefix $(obj)/,$(NVIDIA_OBJECTS))
$(LD) -r -o $@ $^
But i'm not sure if we actually do any further processing, or use precompiled kernel interface file. |
