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.
config NTB_MSI_TEST
tristate "NTB MSI Test Client"
depends on NTB_MSI
help
This tool demonstrates the use of the NTB MSI library to
send MSI interrupts between peers.
If unsure, say N.
