Dave Jiang 8a7b6a778a ntb: ntb perf tool
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.

config NTB_PINGPONG
tristate "NTB Ping Pong Test Client"
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.
If unsure, say N.
config NTB_TOOL
tristate "NTB Debugging Tool Test Client"
help
This is a simple debugging driver that enables the doorbell and
scratchpad registers to be read and written from the debugfs. This
enables more complicated debugging to be scripted from user space.
This driver may be used to test that your ntb hardware and drivers are
functioning at a basic level.
If unsure, say N.
config NTB_PERF
tristate "NTB RAW Perf Measuring Tool"
help
This is a tool to measure raw NTB performance by transferring data
to and from the window without additional software interaction.
If unsure, say N.
