Providing raw performance data via a tool that directly access data from NTB w/o any software overhead. This allows measurement of the hardware performance limit. In revision one we are only doing single direction CPU and DMA writes. Eventually we will provide bi-directional writes. The measurement using DMA engine for NTB performance measure does not measure the raw performance of DMA engine over NTB due to software overhead. But it should provide the peak performance through the Linux DMA driver.

help
|
|
This is a simple ping pong driver that exercises the scratchpads 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.

help
|
|
This is a simple debugging driver that enables the doorbell and
|
|
scratchpad registers to be read and written from the debugfs. This
