[PATCH v3 1/5] tools: arm64: Add a Makefile for generating sysreg-defs.h

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Use a common Makefile for generating sysreg-defs.h, which will soon be
needed by perf and KVM selftests. The naming scheme of the generated
macros is not expected to change, so just refer to the canonical
script/data in the kernel source rather than copying to tools.
