The NTB drivers currently support only one hardware driver, and one client type. This patch set adds an abstraction layer, enabling hardware drivers by other vendors, and clients other than ntb_transport. The commits in this set may also be pulled from: github.com/allenbh/linux tagged ntb-abh-v3 Compare against tags ntb-abh-v1 and ntb-abh-v2 to see the differences in the each revised version of this series. Different in v3: - Reschedule long running tasklets to avoid stalls in transport. - Initialize driver .owner and .name in ntb_register_client. - Eliminate calls to BUG() in ntb_hw_intel. - Fix incorrect PBARXLAT split-bar address assignment in ntb_hw_intel. - Add bugfix patch: Read peer info from local SPAD in transport. - Arrange the above bugfix, and three patches affecting transport link down, to earlier in the series, because they are higher importance. - Add performance patch: Increase transport MTU to 64k form 16k. - Rebase on ff25ea8f4eee to resolve a merge conflict in MAINTAINERS (conflicting context lines only, no conflicting changes). Different in v2: - Rewrite shortlog descriptions for spelling and style - Remove extraneous NTB dependency from Kconfig files - Reindent Kconfig files with leading tabs - Reindent some lines in ntb_transport - Append patch NTB: Rename intel hw to proper platform names Allen Hubbe (11): NTB: Move files in preparation for NTB abstraction NTB: Add NTB hardware abstraction layer 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 (7): 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 hw to proper platform names NTB: Increase transport MTU to 64k from 16k Documentation/ntb.txt | 127 ++ MAINTAINERS | 16 +- drivers/net/ntb_netdev.c | 58 +- drivers/ntb/Kconfig | 39 +- drivers/ntb/Makefile | 4 +- 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 | 2214 +++++++++++++++++++++++++++++++++++ drivers/ntb/hw/intel/ntb_hw_intel.h | 342 ++++++ drivers/ntb/ntb.c | 251 ++++ drivers/ntb/ntb_hw.c | 1896 ------------------------------ drivers/ntb/ntb_hw.h | 256 ---- drivers/ntb/ntb_regs.h | 177 --- drivers/ntb/ntb_transport.c | 1025 +++++++++------- 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 ++ 22 files changed, 5482 insertions(+), 2815 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 -- 2.4.0.rc0.43.gcf8a8c6 -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
