[PATCH v3 0/9] NTB: Alter kernel API to support multi-port devices
There are devices, like IDT PCIe-switches, which have more than just two ports. Particularly one device can have up to eight ports with NTB-function activated. In order to support such devices, NTB kernel API should be altered since currently it's optimized to work with two-ports devices only. Changelog v2: - Move comments from cover letter to individual patches - Combine patches to make code buildable - Alter patchset to support Intel SKX driver - Make sure all the API uses the same midx/widx/pidx/sidx arguments notation - Move new MW API usage description into Documention - Alter Spad/Msg API checking valid function to make spad and msg interfaces optional - Alter comments in ntb.h - Split: add NTB_SPEED_GEN4 and ntb.h comments into separate patches - Put copyrights into some of the existing patches - Get rid of TOPO updates Changelog v3: - Get rid of code rearrangements within Intel/AMD drivers - Make two-ports NTB API being default - Check pidx argument for negative values - Translation address methods should return zero in case if not implemented - Simplify Scratchpad alterations of ntb_tool client driver - ntb.h comments are altered in compliance with port-related API changes - Spell check the text Serge Semin (9): NTB: Make link-state API being declared first NTB: Add indexed ports NTB API NTB: Alter link-state API to support multi-port devices NTB: Alter MW API to support multi-ports devices NTB: Alter Scratchpads API to support multi-ports devices NTB: Add Messaging NTB API NTB: Add new Memory Windows API documentation NTB: Add PCIe Gen4 link speed NTB: Add ntb.h comments Documentation/ntb.txt | 99 - drivers/ntb/hw/amd/ntb_hw_amd.c | 84 +++-- drivers/ntb/hw/intel/ntb_hw_intel.c | 106 -- drivers/ntb/ntb.c | 69 drivers/ntb/ntb_transport.c | 44 ++- drivers/ntb/test/ntb_perf.c | 27 +- drivers/ntb/test/ntb_pingpong.c | 14 +- drivers/ntb/test/ntb_tool.c | 69 +++- include/linux/ntb.h | 724 ++-- 9 files changed, 1026 insertions(+), 210 deletions(-) -- 2.6.6
