New versions of the Vivante kernel driver don't trust the hardware feature bits anymore, but use an internal hardware database. This also includes more feature fields than are available in hardware. As we can't trust the hardware feature bits to be correct anymore, we need to replicate the HWDB in etanviv. For now only the GC7000L as found on the i.MX8M is supported.
