NTB: Add ping pong test client 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.

NTB: Add tool test client This is a simple debugging driver that enables the doorbell and scratch pad registers to be read and written from the debugfs. This tool 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.

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.

NTB: Introduce NTB MSI Test Client Introduce a tool to test NTB MSI interrupts similar to the other NTB test tools. This tool creates a debugfs directory for each NTB device with the following files: port irqX_occurrences peerX/port peerX/count peerX/trigger The 'port' file tells the user the local port number and the 'occurrences' files tell the number of local interrupts that have been received for each interrupt. For each peer, the 'port' file and the 'count' file tell you the peer's port number and number of interrupts respectively. Writing the interrupt number to the 'trigger' file triggers the interrupt handler for the peer which should increment their corresponding 'occurrences' file. The 'ready' file indicates if a peer is ready, writing to this file blocks until it is ready. The module parameter num_irqs can be used to set the number of local interrupts. By default this is 4. This is only limited by the number of unused MSI interrupts registered by the hardware (this will require support of the hardware driver) and there must be at least 2*num_irqs + 1 spads registers available.
