Vulkan memory type for immutable vertex/index buffers

AR5

Hi.

What is the recommended Vulkan memory type for immutable vertex/index buffers?
According to Arm Mali GPU Best Practices - the best memory type for that kind of usage (immutable resources) should have only HOST_VISIBLE | HOST_COHERENT bits.
Does that mean that there is no need to use DEVICE_LOCAL_BIT at all on ARM Mali hardware? if not what are the usage scenarios for DEVICE_LOCAL_BIT?

    Thank you for the answer! One more thing I wanted to clarify - does that mean that there is no need at all to use DEVICE_LOCAL bit on ARM mobile systems?

    Or would be there a benefit for having DEVICE_LOCAL | HOST_VISIBLE combination?
