* ntb_pingpong: Add a debugfs file to get the ping countLogan Gunthorpe2016-08-051-1/+61
| | | | | | | | | | | | | This commit adds a debugfs 'count' file to ntb_pingpong. This is so testing with ntb_pingpong can be automated beyond just checking the logs for pong messages. The count file returns a number which increments every pong. The counter can be cleared by writing a zero.

* NTB: Add ping pong test clientAllen Hubbe2015-07-041-0/+250
This is a simple ping pong driver that exercises the scratch pads and doorbells of the ntb hardware. This driver may be used to test that your ntb hardware and drivers are functioning at a basic level. Signed-off-by: Allen Hubbe <Allen.Hubbe@emc.com> Signed-off-by: Jon Mason <jdmason@kudzu.us>
