In linux Kernel 5.11-rc3,

starting with make ARCH=riscv rv32_defconfig

and then

make ARCH=riscv menufconfig

the configuration option

Platform Type => "Emit compressed instruction when building Linux "

cannot be modified

I do see the following line in the generated .config file

CONFIG_RISCV_ISA_C=y

Is there a way to disable the generation of compressed instructions?

Thanks

Look at the help text for RISCV_ISA_C, it's selected by EFI.
