It includes a pretty significant reworking of the NTB core code, but has already produced some significant perf improvements. Thanks, Jon --- The following changes since commit d8133356e99713bd023b229de107ddd6dd6d375a: Merge tag 'pci-v4.2-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci (2015-06-23 13:41:24 -0700) are available in the git repository at: git://github.com/jonmason/ntb tags/ntb-4.2 for you to fetch changes up to bf44fe4671f97ee17d178e08c2d3b346188d062b: NTB: Add split BAR output for debugfs stats (2015-07-04 14:09:32 -0400) ---------------------------------------------------------------- A very significant modification to NTB in this series. An abstraction layer was added to allow the hardware and clients to be easily added. This required rewriting the NTB transport layer for this abstraction layer. This modification will allow future "high performance" NTB clients. In addition to this change, a number of performance modifications were added. These changes include NUMA enablement, using CPU memcpy instead of asyncdma, and modification of NTB layer MTU size. ---------------------------------------------------------------- Allen Hubbe (12): NTB: Move files in preparation for NTB abstraction NTB: Add NTB hardware abstraction layer NTB: Split ntb_hw_intel and ntb_transport drivers NTB: Differentiate transport link down messages NTB: Do not advance transport RX on link down NTB: Reset transport QP link stats on down NTB: Add parameters for Intel SNB B2B addresses NTB: Add ping pong test client NTB: Add tool test client NTB: Rate limit ntb_qp_link_work NTB: Use NUMA memory and DMA chan in transport NTB: Use NUMA memory in Intel driver Dave Jiang (10): NTB: Read peer info from local SPAD in transport NTB: Enable link for Intel root port mode in probe NTB: Check the device ID to set errata flags NTB: Improve performance with write combining NTB: Default to CPU memcpy for performance NTB: Rename Intel code names to platform names NTB: Increase transport MTU to 64k from 16k NTB: Print driver name and version in module init NTB: Change WARN_ON_ONCE to pr_warn_once on unsafe NTB: Add split BAR output for debugfs stats Documentation/ntb.txt | 127 ++ MAINTAINERS | 12 +- drivers/net/Kconfig | 4 +- drivers/net/ntb_netdev.c | 58 +- drivers/ntb/Kconfig | 39 +- drivers/ntb/Makefile | 5 +- drivers/ntb/hw/Kconfig | 1 + drivers/ntb/hw/Makefile | 1 + drivers/ntb/hw/intel/Kconfig | 7 + drivers/ntb/hw/intel/Makefile | 1 + drivers/ntb/hw/intel/ntb_hw_intel.c | 2274 +++++++++++++++++++++++++++++++++++ drivers/ntb/hw/intel/ntb_hw_intel.h | 342 ++++++ drivers/ntb/ntb.c | 251 ++++ drivers/ntb/ntb_hw.c | 1895 ----------------------------- drivers/ntb/ntb_hw.h | 256 ---- drivers/ntb/ntb_regs.h | 177 --- drivers/ntb/ntb_transport.c | 1029 +++++++++------- drivers/ntb/test/Kconfig | 19 + drivers/ntb/test/Makefile | 2 + drivers/ntb/test/ntb_pingpong.c | 250 ++++ drivers/ntb/test/ntb_tool.c | 556 +++++++++ include/linux/ntb.h | 970 ++++++++++++++- include/linux/ntb_transport.h | 85 ++ 23 files changed, 5545 insertions(+), 2816 deletions(-) create mode 100644 Documentation/ntb.txt create mode 100644 drivers/ntb/hw/Kconfig create mode 100644 drivers/ntb/hw/Makefile create mode 100644 drivers/ntb/hw/intel/Kconfig create mode 100644 drivers/ntb/hw/intel/Makefile create mode 100644 drivers/ntb/hw/intel/ntb_hw_intel.c create mode 100644 drivers/ntb/hw/intel/ntb_hw_intel.h create mode 100644 drivers/ntb/ntb.c delete mode 100644 drivers/ntb/ntb_hw.c delete mode 100644 drivers/ntb/ntb_hw.h delete mode 100644 drivers/ntb/ntb_regs.h create mode 100644 drivers/ntb/test/Kconfig create mode 100644 drivers/ntb/test/Makefile create mode 100644 drivers/ntb/test/ntb_pingpong.c create mode 100644 drivers/ntb/test/ntb_tool.c create mode 100644 include/linux/ntb_transport.h -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
