NTB: ntb_test: Fix bug when counting remote files

2020-06-06T00:02:09+00:00

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.

NTB: Add ntb_msi_test support to ntb_test

2019-06-13T13:02:59+00:00

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. Signed-off-by: Logan Gunthorpe Cc: Dave Jiang Cc: Allen Hubbe Signed-off-by: Jon Mason

NTB: ntb_test: Update ntb_perf tests

2018-01-29T03:17:24+00:00

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 Signed-off-by: Jon Mason

NTB: ntb_test: Update ntb_tool MW tests

2018-01-29T03:17:24+00:00

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 Signed-off-by: Jon Mason

NTB: ntb_test: Add ntb_tool Message tests

2018-01-29T03:17:24+00:00

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 Signed-off-by: Jon Mason

NTB: ntb_test: Update ntb_tool Scratchpad tests

2018-01-29T03:17:24+00:00

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 Signed-off-by: Jon Mason

NTB: ntb_test: Update ntb_tool DB tests

2018-01-29T03:17:24+00:00

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. Signed-off-by: Serge Semin Signed-off-by: Jon Mason

NTB: ntb_test: Update ntb_tool link tests

2018-01-29T03:17:24+00:00

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.
