The latest PCIe IP released by XILINX (axi_pcie_v2_7) could be configured at hardware build time either as a root port or as an end point. The support for Root Port configuration has been intergrated with the latest Zynq as well as Microblaze Linux Kernel. This PCIe core supports the Zynq and 7-series Device family. This page mainly discusses the Root Port driver and an example end point driver is demonstrated in TRD release with links pointed at the end of this page. Has anyone found an example driver that uses the new-ish scatterlist API (dma_map_sg, etc, for 2.6.26+)? Ayashi No Ceres Scan Italy Earthquake. I have lots of disjoint documentation but no example code. This page used to contain an example source code of complete Linux PCIe driver for Altera Stratix V FPGA. However, this example became outdated. Harvestman The Biology Of Opiliones Vs Cellar.

Introduction to Linux - A Hands on Guide This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter. For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I would like to say that I have used this Forum in the past and that there is very useful information. I am a software engineer with experience developing Linux device drivers (USB 2.0). I used the usb-skeleton template by Greg Kroah-Hartman, which was of great help. I need to develop now a device driver for a PCI express board: the Xilinx Virtex-5 LXT/SXT and I am a little bit lost. I know nothing about PCIe.

So my first question is: Is there a similar template for PCIe to start with? Any advice would be more than welcome! Happy Christmas! Hi magda, I'm an electrical engineer an I don't know a lot of thing about the inside of the linux kernel and how to make device drivers. But, me too I am trying to develop a PCI express device driver for Xilinx Virtex-5 SXT. I was reading books 'Linux Device Drivers' and 'PCI Express system architecture' but I don't think there is enough info in these book to do that. I will firstly try to make an USB driver (If you use ML-506 evaluation board or equivalent there is already an USB device port.) If you have any more info about pci express let me know.

Hi, here you have links to pci skeletons that I've found useful, from the simplest to the most complicated: Linux Device Drivers is quite complete boot, just follow chapter 9 and edit pci_skel.c (first of the previous links) accordingly in order to get simple read and write operations. Also you need to decide if you want your driver to be a Character or a Block device, here you have some discussions: In case you go for Character Device then you will need to create it from a linux terminal. I don´t have the info on how to do that yet. I hope this helps, Magda. You are welcome, I am glad the info was useful. Let me know if you have any problem.
