2020-06-05NTB: ntb_test: Fix bug when counting remote filesLogan Gunthorpe1-1/+1
When remote files are counted in get_files_count, without using SSH, the code returns 0 because there is a colon prepended to $LOC. $VPATH should have been used instead of $LOC.

2019-06-13NTB: Add ntb_msi_test support to ntb_testLogan Gunthorpe1-2/+52
When the ntb_msi_test module is available, the test code will trigger each of the interrupts and ensure the corresponding occurrences files gets incremented.

2018-01-28NTB: ntb_test: Update ntb_perf testsSerge Semin1-6/+7
ntb_perf driver has been also updated so to have the multi-port interface support. User now must specify what peer port is going to be used to perform the test. Signed-off-by: Serge Semin <fancer.lancer@gmail.com> Signed-off-by: Jon Mason <jdmason@kudzu.us>
2018-01-28NTB: ntb_test: Update ntb_tool MW testsSerge Semin1-21/+68
There are devices (like IDT PCIe switches), which outbound MWs xlat address is setup on peer side. In this case local side is supposed to allocate a memory buffer and somehow deliver the xlat DMA address to peer so one could set the outbound MW up. The MW test is altered so to support both previous Intel/AMD and new IDT-like devices. Signed-off-by: Serge Semin <fancer.lancer@gmail.com> Signed-off-by: Jon Mason <jdmason@kudzu.us>
2018-01-28NTB: ntb_test: Add ntb_tool Message testsSerge Semin1-0/+37
Messages NTB API is now available. ntb_tool driver has been altered to perform messages send and receive operation. The test of messages read/write to/from peer device has been added to the script. Signed-off-by: Serge Semin <fancer.lancer@gmail.com> Signed-off-by: Jon Mason <jdmason@kudzu.us>
2018-01-28NTB: ntb_test: Update ntb_tool Scratchpad testsSerge Semin1-17/+26
Scratchpad NTB API has changed so has the ntb_tool driver. Outbound Scratchpad DebugFS files have been moved to peer specific directories. Each scratchpad is now available via separate file. The test code has been accordingly altered. Signed-off-by: Serge Semin <fancer.lancer@gmail.com> Signed-off-by: Jon Mason <jdmason@kudzu.us>
2018-01-28NTB: ntb_test: Update ntb_tool DB testsSerge Semin1-11/+18
DB interface of ntb_tool driver hasn't been changed much, but db_valid_mask DebugFS file has still been added. In this case it's much better to test all valid DB bits instead of using the predefined mask, which may be incorrect in general.

2018-01-28NTB: ntb_test: Update ntb_tool link testsSerge Semin1-11/+15
Link Up and Down methods are used to change NTB link settings on local side only for multi-port devices. Link is considered up only if both sides local and peer set it up. Intel/AMD hardware acts a bit different by assigning the Primary and Secondary roles, so Primary device only is able to change the link state. Such behaviour should be reflected in the test code.

2018-01-28NTB: ntb_test: Add ntb_tool port testsSerge Semin1-0/+52
Multi-port interface is now available in ntb_tool driver. According to the new NTB API, there might be more than two devices connected over NTB. It means each device can have multiple freely enumerated ports. Each port got index assigned by NTB hardware driver. This test is performed to determine the local and peer ports as well as their indexes. Signed-off-by: Serge Semin <fancer.lancer@gmail.com> Signed-off-by: Jon Mason <jdmason@kudzu.us>

2017-08-01ntb: ntb_test: ensure the link is up before trying to configure the mwsLogan Gunthorpe1-0/+4
After the link tests, there is a race on one side of the test for the link coming up. It's possible, in some cases, for the test script to write to the 'peer_trans' files before the link has come up. To fix this, we simply use the link event file to ensure both sides see the link as up before continuning.

2017-06-19NTB: ntb_test: fix bug printing ntb_perf resultsLogan Gunthorpe1-1/+1

2016-08-05ntb_test: Add a selftest script for the NTB subsystemLogan Gunthorpe1-0/+422
This script automates testing doorbells, scratchpads and memory windows for an NTB device. It can be run locally, with the NTB looped back to the same host or use SSH to remotely control the second host. In the single host case, the script just needs to be passed two arguments: a PCI ID for each side of the link. In the two host case the -r option must be used to specify the remote hostname (which must be SSH accessible and should probably have ssh-keys exchanged). A sample run looks like this: $ sudo ./ntb_test.sh 0000:03:00.1 0000:83:00.1 -p 29 Starting ntb_tool tests...
