    The VFP support code only looks at bits 19-16 to determine the VFP version. On Qualcomm's processors (Krait and Scorpion) we should see that we have HWCAP_VFPv3 but we don't because bit 22 is set to 1 to indicate that the subarchitecture is not implemented by ARM and the rest of the bits are left as 0 because this is the first subarchitecture ...

    https://patchwork.kernel.org/patch/5080391/
    Oct 14, 2014 · This was discussed a few years ago, and some people raised various objections. Off the top of my head: - Some features (e.g. VFP/NEON) need kernel support, and if this is not enabled, the actual system capabilities will not match the raw register value. Fudging the values exposed to userspace would be fragile. (This argument has some merit.)
