Hi, If ieee754 equals EMULATED, then the variables mips_use_nan_2008 and mips_use_nan_legacy are set to true ( https://elixir.bootlin.com/linux/v6.13.6/source/arch/mips/kernel/fpu-probe.c#L208 ) and any binaries are accepted regardless of whether supported by the FPU ( https://elixir.bootlin.com/linux/v6.13.6/source/arch/mips/kernel/elf.c#L154 ).
Kind regards, Aleksandar Rakic
