13 Enable this if you want to use HSA features on AMD GPU devices.
16 bool "Enable HMM-based shared virtual memory manager"
17 depends on HSA_AMD && DEVICE_PRIVATE
22 Enable this to use unified memory and managed memory in HIP. This
23 memory manager supports two modes of operation. One based on
24 preemptions and one based on page faults. To enable page fault
25 based memory management on most GFXv9 GPUs, set the module
26 parameter amdgpu.noretry=0.
29 bool "HSA kernel driver support for peer-to-peer for AMD GPU devices"
30 depends on HSA_AMD && PCI_P2PDMA && DMABUF_MOVE_NOTIFY
32 Enable peer-to-peer (P2P) communication between AMD GPUs over
33 the PCIe bus. This can improve performance of multi-GPU compute
34 applications and libraries by enabling GPUs to access data directly
35 in peer GPUs' memory without intermediate copies in system memory.
37 This P2P feature is only enabled on compatible chipsets, and between
38 GPUs with large memory BARs that expose the entire VRAM in PCIe bus
39 address space within the physical address limits of the GPUs.
