How to enable NEON ARM in Linux in IMX6Q Envirment

[KrishnaPrasad1z]

Hi All,

Whether for NEON any settings need to be done other than kernel config?

In the Linux Kernel Config, NEON is set as YES. But whether any other settings need to be done to enable NEON?

In the linux version kernel originally asm_neon.h was not there.

Does this means that the kernel doesn’t support NEON?

In iMX6X Environment,

Whether any option need to be additionally applied for Cortex-A9 case?

Thanks in Advance

try the following:

1. install gcc (./ltib -m prep -p gcc && ./ltib -m scbuild -p gcc && ./ltib -m scinstall -p gcc)

2. include the compilation flag -mfpu=neon.
