But the test drivers still were left almost unchanged. Yes, they didn't fail being used with new NTB API, but they only worked with two-ports NTB devices. This patchset is intended to fix the issue by amending the NTB test drivers and script so they would be fully compatible with multi-port NTB API. Additionally I found a few NTB subsystem issues while developing the submitted patches. So they are also fixed in this patchset. The patchset is applied on top of the recent Jon Mason's repo state: https://github.com/jonmason/ntb Particularly the "ntb/ntb-next" branch is used. The last commit hash had been: commit ("ntb_hw_switchtec: Force down the link before") Serge Semin (15): NTB: Rename NTB messaging API methods NTB: Set dma mask and dma coherent mask to NTB devices NTB: Fix UB/bug in ntb_mw_get_align() NTB: ntb_pp: Add full multi-port NTB API support NTB: ntb_tool: Add full multi-port NTB API support NTB: ntb_perf: Add full multi-port NTB API support NTB: ntb_test: Safely use paths with whitespace NTB: ntb_test: Add ntb_tool port tests NTB: ntb_test: Update ntb_tool link tests NTB: ntb_test: Update ntb_tool DB tests NTB: ntb_test: Update ntb_tool Scratchpad tests NTB: ntb_test: Add ntb_tool Message tests NTB: ntb_test: Update ntb_tool MW tests NTB: ntb_test: Update ntb_perf tests NTB: ntb_hw_idt: Set NTB_TOPO_SWITCH topology drivers/ntb/hw/amd/ntb_hw_amd.c | 4 + drivers/ntb/hw/idt/ntb_hw_idt.c | 37 +- drivers/ntb/hw/intel/ntb_hw_intel.c | 4 + drivers/ntb/ntb.c | 1 - drivers/ntb/test/ntb_perf.c | 1820 +++++++++++++++++++++---------- drivers/ntb/test/ntb_pingpong.c | 447 +++++--- drivers/ntb/test/ntb_tool.c | 1820 +++++++++++++++++++++---------- include/linux/ntb.h | 36 +- tools/testing/selftests/ntb/ntb_test.sh | 307 ++++-- 9 files changed, 3018 insertions(+), 1458 deletions(-) -- 2.12.0
