There may yet be changes made to this ABI, so it's # for testing only. # # rfscv is implemented to return from scv type system calls. It can not # be used to return from sc system calls because those are defined to # preserve lr. # # In a comparison of getpid syscall, the test program had scv taking # about 3 more cycles in user mode (92 vs 89 for sc), due to lr handling. # getpid syscall throughput on POWER9 is improved by 33%, mostly due to # reducing mtmsr and mtspr. # # Signed-off-by: Nicholas Piggin <npiggin@gmail.com> # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 4c6be9192dbbe4aff7d42057d7864df8a5f3baf2 # < make -s -j 20 ARCH=powerpc O=/kisskb/build/npiggin_ppc64e_defconfig+UP_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- ppc64e_defconfig # Added to kconfig CONFIG_SMP=n # < make -s -j 20 ARCH=powerpc O=/kisskb/build/npiggin_ppc64e_defconfig+UP_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 20 ARCH=powerpc O=/kisskb/build/npiggin_ppc64e_defconfig+UP_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig # make -s -j 20 ARCH=powerpc O=/kisskb/build/npiggin_ppc64e_defconfig+UP_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- INFO: Uncompressed kernel (size 0xb64ad0) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0xc00000) Image Name: Linux-5.6.0-rc2-g4c6be9192dbb Created: Wed May 13 19:39:07 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 4789123 Bytes = 4676.88 KiB = 4.57 MiB Load Address: 00000000 Entry Point: 00000000 Completed OK # rm -rf /kisskb/build/npiggin_ppc64e_defconfig+UP_powerpc-gcc4.9 # Build took: 0:02:08.864984
