PCIe Dummy Driver

  • We have a existed PCIe device. I use it to exercise a basic PCIe dummy driver. The probe() will be called if the PID/VID matched.
  • Environment:
    • aarch64 GNU/Linux
    • uname -r, 4.14.0-19.913.1-be-arm64

Test the system calls to copy data between kernel and user space

  • Behavior:

    • AP read a binary file and write to device driver, 64KB/time.
    • AP read the total size of written data from driver.

  • Please install kernel headers first:

sudo apt-get install linux-headers-generic
  • Usage:
$ make check
  • Generate binary file for test
$ dd if=/dev/zero of=test.bin bs=65K count=1
