Hi,
I am trying to enable Advanced SIMD and VFP in the linux kernel by setting
the FPEXC.EN bit.
To set that bit I am using the VMSR instruction. But the assembler gives
"bad instruction: vmsr fpexc, r1" error.
Are the vmsr / vmrs instructions supported by the toolchain?
Is there any other way to enable Advanced SIMD and VFP support in the linux
kernel?
Thanks,
--Akshay
