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. # < /opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-gcc --version # < /opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-ld --version # < git log --format=%s --max-count=1 ec1f086ef2b0202c6e9ef10c1bfbc0b4fe69e00b # < make -s -j 10 ARCH=powerpc O=/kisskb/build/npiggin_ppc64e_defconfig+UP_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- ppc64e_defconfig # Added to kconfig CONFIG_SMP=n # < make -s -j 10 ARCH=powerpc O=/kisskb/build/npiggin_ppc64e_defconfig+UP_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- help # make -s -j 10 ARCH=powerpc O=/kisskb/build/npiggin_ppc64e_defconfig+UP_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- olddefconfig # make -s -j 10 ARCH=powerpc O=/kisskb/build/npiggin_ppc64e_defconfig+UP_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- /kisskb/src/kernel/printk/printk.c: In function 'devkmsg_sysctl_set_loglvl': /kisskb/src/kernel/printk/printk.c:204:16: warning: 'old' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/kernel/trace/trace_events.c: In function 'event_create_dir': /kisskb/src/kernel/trace/trace_events.c:2040:6: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c: In function 'proc_reg_open': /kisskb/src/include/linux/list.h:72:12: warning: 'pdeo' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c:338:21: note: 'pdeo' was declared here /kisskb/src/arch/powerpc/kernel/entry_64.S: Assembler messages: /kisskb/src/arch/powerpc/kernel/entry_64.S:67: Error: Unrecognized opcode: `interrupt_to_kernel' /kisskb/src/arch/powerpc/kernel/entry_64.S:164: Error: Unrecognized opcode: `rfscv_to_user' make[3]: * [/kisskb/src/scripts/Makefile.build:350: arch/powerpc/kernel/entry_64.o] Error 1 make[2]: * [/kisskb/src/scripts/Makefile.build:505: arch/powerpc/kernel] Error 2 make[1]: * [/kisskb/src/Makefile:1681: arch/powerpc] Error 2 make[1]: * Waiting for unfinished jobs.... /kisskb/src/fs/ext4/extents.c: In function 'ext4_convert_unwritten_io_end_vec': /kisskb/src/fs/ext4/extents.c:5009:23: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/udf/unicode.c: In function 'udf_name_conv_char': /kisskb/src/fs/udf/unicode.c:132:8: warning: 'c' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/nfsd/nfs4xdr.c: In function 'nfsd4_encode_components_esc': /kisskb/src/fs/nfsd/nfs4xdr.c:2151:9: warning: 'str' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/io_uring.c: In function '__io_sqe_files_update': /kisskb/src/fs/io_uring.c:5819:13: warning: 'err' may be used uninitialized in this function [-Wuninitialized] make: *** [Makefile:179: sub-make] Error 2 Command 'make -s -j 10 ARCH=powerpc O=/kisskb/build/npiggin_ppc64e_defconfig+UP_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- ' returned non-zero exit status 2 # rm -rf /kisskb/build/npiggin_ppc64e_defconfig+UP_powerpc-gcc4.6 # Build took: 0:01:27.867560
