The 883 kernel and userspace programs may not be able to run at all on systems 884 that do not support unaligned memory accesses. 885 886config RISCV_EFFICIENT_VECTOR_UNALIGNED_ACCESS 887 bool "Assume the system supports fast vector unaligned memory accesses" 888 depends on NONPORTABLE 889 help 890 Assume that the system supports fast vector unaligned memory accesses. When 891 enabled, this option improves the performance of the kernel on such 892 systems. However, the kernel and userspace programs will run much more 893 slowly, or will not be able to run at all, on systems that do not 894 support efficient unaligned memory accesses. 895 |
