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-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux-ld --version # < git log --format=%s --max-count=1 5f60bb2254dec0233f5190a51b35bb5a2688de94 # < make -s -j 160 ARCH=x86 O=/kisskb/build/npiggin_x86-allmodconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux- allmodconfig # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # Added to kconfig CONFIG_SAMPLES=n # < make -s -j 160 ARCH=x86 O=/kisskb/build/npiggin_x86-allmodconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux- help # make -s -j 160 ARCH=x86 O=/kisskb/build/npiggin_x86-allmodconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux- olddefconfig # make -s -j 160 ARCH=x86 O=/kisskb/build/npiggin_x86-allmodconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux- Completed OK # rm -rf /kisskb/build/npiggin_x86-allmodconfig_x86_64-gcc8 # Build took: 0:06:28.657312
