is it possible to flush/invalidate cache from user space for AARCH32

yang

Hi,

When AARCH64 works at AARCH32 mode, is it possible to flush/invalidate cache from user space? i know AARCH64 can do that, but is it capable for AARCH32?

i am working on a user space driver and i need flush/invalidate cache line from user space, it is a NXP CPU with A53 core, works at 32bit AARCH32 mode, may i know can i do it in user space?

Thanks
