+	  Enable this to use unified memory and managed memory in HIP. This
+	  memory manager supports two modes of operation. One based on
+	  preemptions and one based on page faults. To enable page fault
+	  based memory management on most GFXv9 GPUs, set the module
+	  parameter amdgpu.noretry=0.

+	depends on HSA_AMD && PCI_P2PDMA && DMABUF_MOVE_NOTIFY
+	help
+	  Enable peer-to-peer (P2P) communication between AMD GPUs over
+	  the PCIe bus. This can improve performance of multi-GPU compute
+	  applications and libraries by enabling GPUs to access data directly
+	  in peer GPUs' memory without intermediate copies in system memory.
+
+	  This P2P feature is only enabled on compatible chipsets, and between
+	  GPUs with large memory BARs that expose the entire VRAM in PCIe bus
+	  address space within the physical address limits of the GPUs.
