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 10 ARCH=powerpc O=/kisskb/build/powerpc-next_83xx_mpc836x_rdk_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- 83xx/mpc836x_rdk_defconfig # make -s -j 10 ARCH=powerpc O=/kisskb/build/powerpc-next_83xx_mpc836x_rdk_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- INFO: Uncompressed kernel (size 0x5303e0) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) Image Name: Linux-5.0.0-rc2-g088522fdd7cc Created: Tue Feb 19 16:10:41 2019 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2658125 Bytes = 2595.83 KiB = 2.53 MiB Load Address: 00000000 Entry Point: 00000000 Completed OK # rm -rf /kisskb/build/powerpc-next_83xx_mpc836x_rdk_defconfig_powerpc-gcc5 # Build took: 0:00:46.898677
