Section 7.6 in Book III of # the ISA outlines how to calculate the percentage of shared resources # for threads using the ratio of the PURR delta and Timebase Register # delta for a sampled period. # # This calculation is currently done erroneously by the lparstat tool # from the powerpc-utils package. This patch exports the current # timebase value after we sample the PURRs and exposes it to userspace # accounting tools via /proc/ppc64/lparcfg. # # Signed-off-by: Tyrel Datwyler # Signed-off-by: Michael Ellerman # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 088522fdd7cc3537bd8ae8c9fa54be139b857a76 # < make -s -j 8 ARCH=powerpc O=/kisskb/build/powerpc-next_40x_kilauea_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- 40x/kilauea_defconfig # make -s -j 8 ARCH=powerpc O=/kisskb/build/powerpc-next_40x_kilauea_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- /kisskb/src/arch/powerpc/kernel/head_40x.S: Assembler messages: /kisskb/src/arch/powerpc/kernel/head_40x.S:886: Warning: invalid register expression Completed OK # rm -rf /kisskb/build/powerpc-next_40x_kilauea_defconfig_powerpc-gcc5 # Build took: 0:00:50.320190
