[PATCH 00/16] Intel FPGA Device Drivers

From: Wu Hao
Date: Thu Mar 30 2017 - 08:13:13 EST


Hi All,

Here is a patch-series adding drivers for Intel FPGA devices.

The Intel FPGA driver provides interfaces for userspace applications to
configure, enumerate, open, and access FPGA accelerators on platforms
equipped with Intel(R) FPGA solutions and enables system level management
functions such as FPGA partial reconfiguration, power management and
virtualization.

This patch series only adds the basic functions for FPGA accelerators and
partial reconfiguration. Patches for more functions, e.g power management
and virtualization, will be submitted after this series gets reviewed.

Patch 1: add a document for Intel FPGA driver overview, including the HW
architecture, driver organization, device enumeration, virtualization and
opens.

Patch 2: introduce a fpga-dev class. It's used in below Intel FPGA PCIe
device driver, to represent a FPGA device on the system, and all actual
feature devices should be registered as child nodes of this container
fpga-dev device.

Patch 3-7: implement Intel FPGA PCIe device driver. It walks through the
'Device Feature List' in the PCI Bar, creates the container fpga-dev as
parent and platform devices as children for the feature devices it found.

Patch 8-11: implement Intel FPGA Management Engine (FME) driver. It's a
platform driver matching with the FME platform device created by above
PCIe driver. Sysfs and device file ioctls are exposed as user interfaces
to allow partial reconfiguration to Accelerated Function Units (AFUs) from
user space applications.

Patch 12-16: implement Intel FPGA Accelerated Function Unit (AFU) driver.
It's a platform driver matching with AFU platform device created by above
PCIe driver. It provides user interfaces to expose the AFU MMIO region,
map/unmap dma buffer, and control the port which AFU connects to.
