a6bed7a5 - NTB: Introduce NTB MSI Test Client

Thu, 23 May 2019 22:30:57 +0000

NTB: Introduce NTB MSI Test ClientIntroduce a tool to test NTB MSI interrupts similar to the otherNTB test tools. This tool creates a debugfs directory for eachNTB device with the following files:portirqX_occurrencespeerX/portpeerX/countpeerX/triggerThe 'port' file tells the user the local port number and the'occurrences' files tell the number of local interrupts thathave been received for each interrupt.For each peer, the 'port' file and the 'count' file tell you thepeer's port number and number of interrupts respectively. Writingthe interrupt number to the 'trigger' file triggers the interrupthandler 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 oflocal interrupts. By default this is 4. This is only limited bythe number of unused MSI interrupts registered by the hardware(this will require support of the hardware driver) and there mustbe at least 2*num_irqs + 1 spads registers available.Signed-off-by: Logan Gunthorpe Cc: Dave Jiang Cc: Allen Hubbe Signed-off-by: Jon Mason List of files: /linux-6.15/drivers/ntb/test/Makefile

8a7b6a77 - ntb: ntb perf tool

Wed, 13 Jan 2016 20:29:48 +0000

ntb: ntb perf toolProviding raw performance data via a tool that directly access data fromNTB w/o any software overhead. This allows measurement of the hardwareperformance limit. In revision one we are only doing single directionCPU and DMA writes. Eventually we will provide bi-directional writes.The measurement using DMA engine for NTB performance measure doesnot measure the raw performance of DMA engine over NTB due to softwareoverhead. But it should provide the peak performance through the Linux DMAdriver.Signed-off-by: Dave Jiang Tested-by: Allen Hubbe Signed-off-by: Jon Mason List of files: /linux-6.15/drivers/ntb/test/Makefile

578b881b - NTB: Add tool test client

Thu, 21 May 2015 06:51:39 +0000

NTB: Add tool test clientThis is a simple debugging driver that enables the doorbell andscratch pad registers to be read and written from the debugfs. Thistool enables more complicated debugging to be scripted from user space.This driver may be used to test that your ntb hardware and drivers arefunctioning at a basic level.Signed-off-by: Allen Hubbe Signed-off-by: Jon Mason List of files: /linux-6.15/drivers/ntb/test/Makefile

963de473 - NTB: Add ping pong test client

NTB: Add ping pong test clientThis is a simple ping pong driver that exercises the scratch pads anddoorbells of the ntb hardware.
