Assessment

Difficulty: 2/5
Estimated time: 1-3 hours
Newbie friendliness: 68/100

Issue type: Bug
Clarity: Mostly clear
Activity status: Active
Tech stack: c, linux
Domain: operating-systems

Research direction

Start with common/inc/nv-linux.h around line 1785 and inspect the of_get_named_gpio function, then reproduce the report with sudo akmods --force on the stated kernel and driver version. Trace the complete build output to identify why the unused chip diagnostic prevents completion; done means the module builds successfully without that failure.
