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
|

If unsure, say N
