Resend now that net-next is open, no code changes. This series continues and refines the previous v28 NBL NIC driver patch set for Nebula-matrix m18110/m18000 (SNIC s1000) Ethernet adapters. The first two foundational patches of v28 have been merged into net-next main branch: - net/nebula-matrix: add minimum nbl build framework (cffde9e49e86) - net/nebula-matrix: add core driver architecture and HW layer initialization (825e6d230163) Following maintainer feedback to shorten the patch series, this iteration drops the two merged commits, reorganizes and polishes the remaining functionality into a standalone 8-patch sequence. No new features are added; this series only completes the pending core infrastructure. The overall driver development plan remains consistent with the v28 two-phase roadmap: 1) Complete hardware initialization, mailbox/channel communication and control-plane infrastructure (this series) 2) Implement netdev registration and TX/RX data-path functionality (follow-up series) This patch set supplements the merged foundational code, covering channel layer abstraction, resource management, interrupt handling, chip-level initialization, control dispatch routing, channel RPC framework, and device lifecycle init/remove/start/stop logic. changes v32->v33 Link to v32:https://lore.kernel.org/netdev/20261021062113.2158-1-illusion.wang@nebula-matrix.com/ changes v31->v32 Link to v31:https://lore.kernel.org/netdev/20261010095939.2230-1-illusion.wang@nebula-matrix.com/ changes v30->v31 Link to v30:https://lore.kernel.org/netdev/20260928123237.88994-1-illusion.wang@nebula-matrix.com/ 1.AI review issues changes v29->v30 Link to v29:https://lore.kernel.org/netdev/20260922120311.86593-1-illusion.wang@nebula-matrix.com/ 1.AI review issues changes v28->v29 Link to v28:https://lore.kernel.org/netdev/20260914123429.56596-1-illusion.wang@nebula-matrix.com/ 1.AI review issues 2.remove the hash table implementation illusion wang (8): net/nebula-matrix: add channel layer net/nebula-matrix: add common resource implementation net/nebula-matrix: add intr resource implementation net/nebula-matrix: add chip-wide hardware init/deinit implementation net/nebula-matrix: dispatch: add control-level routing core infrastructure net/nebula-matrix: dispatch: implement channel RPC framework and serialize hardware ops net/nebula-matrix: add common/ctrl dev init/remove operation net/nebula-matrix: add common dev start/stop operation .../net/ethernet/nebula-matrix/nbl/Makefile | 10 +- .../nbl/nbl_channel/nbl_channel.c | 1528 +++++++++++++++++ .../nbl/nbl_channel/nbl_channel.h | 196 +++ .../nebula-matrix/nbl/nbl_common/nbl_common.c | 52 + .../nebula-matrix/nbl/nbl_common/nbl_common.h | 14 + .../net/ethernet/nebula-matrix/nbl/nbl_core.h | 20 + .../nebula-matrix/nbl/nbl_core/nbl_dev.c | 727 ++++++++ .../nebula-matrix/nbl/nbl_core/nbl_dev.h | 55 + .../nebula-matrix/nbl/nbl_core/nbl_dispatch.c | 671 ++++++++ .../nebula-matrix/nbl/nbl_core/nbl_dispatch.h | 23 + .../nebula-matrix/nbl/nbl_hw/nbl_chip.c | 32 + .../nebula-matrix/nbl/nbl_hw/nbl_chip.h | 12 + .../nbl/nbl_hw/nbl_hw_leonis/nbl_hw_leonis.c | 1286 +++++++++++++- .../nbl/nbl_hw/nbl_hw_leonis/nbl_hw_leonis.h | 342 ++++ .../nbl_hw_leonis/nbl_resource_leonis.c | 370 ++++ .../nbl_hw_leonis/nbl_resource_leonis.h | 12 + .../nebula-matrix/nbl/nbl_hw/nbl_hw_reg.h | 33 + .../nebula-matrix/nbl/nbl_hw/nbl_interrupt.c | 851 +++++++++ .../nebula-matrix/nbl/nbl_hw/nbl_interrupt.h | 21 + .../nebula-matrix/nbl/nbl_hw/nbl_resource.c | 157 ++ .../nebula-matrix/nbl/nbl_hw/nbl_resource.h | 159 ++ .../nbl/nbl_include/nbl_def_channel.h | 175 ++ .../nbl/nbl_include/nbl_def_common.h | 23 + .../nbl/nbl_include/nbl_def_dev.h | 16 + .../nbl/nbl_include/nbl_def_dispatch.h | 83 + .../nbl/nbl_include/nbl_def_hw.h | 80 + .../nbl/nbl_include/nbl_def_resource.h | 38 + .../nbl/nbl_include/nbl_include.h | 28 + .../net/ethernet/nebula-matrix/nbl/nbl_main.c | 289 +++- 29 files changed, 7280 insertions(+), 23 deletions(-) create mode 100644 drivers/net/ethernet/nebula-matrix/nbl/nbl_channel/nbl_channel.c create mode 100644 drivers/net/ethernet/nebula-matrix/nbl/nbl_channel/nbl_channel.h create mode 100644 drivers/net/ethernet/nebula-matrix/nbl/nbl_common/nbl_common.c create mode 100644 drivers/net/ethernet/nebula-matrix/nbl/nbl_common/nbl_common.h create mode 100644 drivers/net/ethernet/nebula-matrix/nbl/nbl_core/nbl_dev.c create mode 100644 drivers/net/ethernet/nebula-matrix/nbl/nbl_core/nbl_dev.h create mode 100644 drivers/net/ethernet/nebula-matrix/nbl/nbl_core/nbl_dispatch.c create mode 100644 drivers/net/ethernet/nebula-matrix/nbl/nbl_core/nbl_dispatch.h create mode 100644 drivers/net/ethernet/nebula-matrix/nbl/nbl_hw/nbl_chip.c create mode 100644 drivers/net/ethernet/nebula-matrix/nbl/nbl_hw/nbl_chip.h create mode 100644 drivers/net/ethernet/nebula-matrix/nbl/nbl_hw/nbl_hw_leonis/nbl_resource_leonis.c create mode 100644 drivers/net/ethernet/nebula-matrix/nbl/nbl_hw/nbl_hw_leonis/nbl_resource_leonis.h create mode 100644 drivers/net/ethernet/nebula-matrix/nbl/nbl_hw/nbl_interrupt.c create mode 100644 drivers/net/ethernet/nebula-matrix/nbl/nbl_hw/nbl_interrupt.h create mode 100644 drivers/net/ethernet/nebula-matrix/nbl/nbl_hw/nbl_resource.c create mode 100644 drivers/net/ethernet/nebula-matrix/nbl/nbl_hw/nbl_resource.h create mode 100644 drivers/net/ethernet/nebula-matrix/nbl/nbl_include/nbl_def_channel.h create mode 100644 drivers/net/ethernet/nebula-matrix/nbl/nbl_include/nbl_def_dev.h create mode 100644 drivers/net/ethernet/nebula-matrix/nbl/nbl_include/nbl_def_dispatch.h create mode 100644 drivers/net/ethernet/nebula-matrix/nbl/nbl_include/nbl_def_resource.h -- 2.51.0.windows.1
