2008 compatibility. Since all software available for Linux/MIPS is
2009 currently 32-bit you should say Y here.
2013 depends on MIPS32_COMPAT
2016 config SYSVIPC_COMPAT
2018 depends on COMPAT && SYSVIPC
2022 bool "Kernel support for o32 binaries"
2023 depends on MIPS32_COMPAT
2025 Select this option if you want to run o32 binaries. These are pure
2026 32-bit binaries as used by the 32-bit Linux/MIPS port. Most of
2027 existing binaries are in this format.
2032 bool "Kernel support for n32 binaries"
2033 depends on MIPS32_COMPAT
2035 Select this option if you want to run n32 binaries. These are
2036 64-bit binaries using 32-bit quantities for addressing and certain
2037 data that would normally be 64-bit. They are used in special
2044 default y if MIPS32_O32 || MIPS32_N32
