From 21adcd5ec99f342489a49e9d237a987b1bd9fab5 Mon Sep 17 00:00:00 2001 From: Khem Raj Date: Mon, 29 Dec 2025 12:45:06 -0800 Subject: [PATCH] tools/power/x86/intel-speed-select: Use pkg-config for libnl-3.0 detection Replace hardcoded libnl3 include path with pkg-config detection to improve portability across different distributions and build environments. The previous implementation used a fixed path constructed from the compiler's sysroot, which could fail on systems with non-standard library installations. Now the build system: - Attempts to detect libnl-3.0 include paths using pkg-config - Falls back to /usr/include/libnl3 if pkg-config is unavailable - Maintains backward compatibility with existing build configurations This ensures the tool builds correctly on a wider range of systems while preserving existing behavior when pkg-config is not present.
