| Enables PCIe card driver for Habana's AI Processors (AIP) that are |
| designed to accelerate Deep Learning inference and training workloads. |
| |
| The driver manages the PCIe devices and provides IOCTL interface for |
| the user to submit workloads to the devices. |
| |
| The user-space interface is described in |
| include/uapi/drm/habanalabs_accel.h |
| |
| If unsure, say N. |
| |
| To compile this driver as a module, choose M here: the |
| module will be called habanalabs. |

| Enable NVMe peer-to-peer direct I/O support for Habanalabs AI |
| accelerators. |
| |
| This allows direct data transfers between NVMe storage devices |
| and Habanalabs accelerators without involving system memory, |
| using PCI peer-to-peer DMA capabilities. |
| |
| Requirements: |
| - CONFIG_PCI_P2PDMA=y |
| - NVMe device and Habanalabs accelerator under same PCI root complex |
| - IOMMU disabled or in passthrough mode |
| - Hardware supporting PCI P2P DMA |
| |
