From 4be61e6b769fc3f97b58870aa4258e27968f07e1 Mon Sep 17 00:00:00 2001 From: Alexander Monakov Date: Sun, 23 Aug 2020 23:27:02 +0300 Subject: tools/power turbostat: Build with _FILE_OFFSET_BITS=64 For compatibility reasons, Glibc off_t is a 32-bit type on 32-bit x86 unless _FILE_OFFSET_BITS=64 is defined. Add this define, as otherwise reading MSRs with index 0x80000000 and above attempts a pread with a negative offset, which fails.
