[PATCH] arm64: defconfig: Enable DMABUF heaps support

Posted by Pratyush Brahma 2 months ago

Enable the DMABUF heaps, system heap and default cma heap,
required on Qualcomm SoCs (e.g. qcm6490) for sharing buffers
across different subsystems.

Which drivers are requiring this? Or explain how exactly the hardware
requires DMABUF?
