Dear all,

A simple EPICS driver example for PCI devices using asynPortDriver on Linux is shared in the following GitHub link in case somebody might be interested,

https://github.com/wanglin86769/cpciEpicsApp

This is an EPICS IOC developed for the LLRF system of a small-scale accelerator facility at CSNS campus. The LLRF board is a customized cPCI FPGA board with PCI 9056 bridge, the control interface is merely register access plus waveform read with 1 second update period, no interrupt or DMA is needed.

The Linux driver part is implemented as kernel module rather than UIO (Userspace I/O). This example is only useful for simple customized PCI devices that does not need interrupt and DMA, and only one MMIO (Memory mapped I/O) BAR is used to access the FPGA registers.

This is my first assignment to control PCI under Linux rather than vxWorks, any suggestion is appreciated.
