Date: Mon, 22 Jul 2019 14:40:04 -0700 From: Shannon Nelson <snelson@...sando.io> To: snelson@...sando.io, netdev@...r.kernel.org, davem@...emloft.net Subject: [PATCH v4 net-next 00/19] Add ionic driver This is a patch series that adds the ionic driver, supporting the Pensando ethernet device. In this initial patchset we implement basic transmit and receive. Later patchsets will add more advanced features. Our thanks to Andrew Lunn, Michal Kubecek, Jacub Kicinski, Jiri Pirko, and the ever present kbuild test robots for their comments and suggestions. New in v4: - use devlink struct alloc for ionic device specific struct - add support for devlink_port - fixup devlink fixed vs running version usage - use bitmap_copy() instead of memcpy() for link_ksettings - don't bother to zero out the advertising bits before copying in the support bits - drop unknown xcvr types (will be expanded on later) - flap the connection to force auto-negotiation - use is_power_of_2() rather than open code - simplify set/get_pauseparam use of pause->autoneg - add a couple comments about NIC status data updated in DMA spaces New in v3: - use le32_to_cpu() on queue_count[] values in debugfs - dma_free_coherent() can handle NULL pointers - remove unused SS_TEST from ethtool handlers - one more case of stop the tx ring if there is no room - remove a couple of stray // comments New in v2: - removed debugfs error checking and cut down on debugfs use - remove redundant bounds checking on incoming values for mtu and ethtool - don't alloc rx_filter memory until the match type has been checked - free the ionic struct on remove - simplified link_up and netif_carrier_ok comparison - put stats into ethtool -S, out of debugfs - moved dev_cmd and dev_info dumping to ethtool -d, out of debugfs - added devlink support - used kernel's rss init routines rather than open code - set the Kbuild dependant on 64BIT - cut down on some unnecessary log messaging - cleaned up ionic_get_link_ksettings - cleaned up other little code bits here and there Shannon Nelson (19): ionic: Add basic framework for IONIC Network device driver ionic: Add hardware init and device commands ionic: Add port management commands ionic: Add basic lif support ionic: Add interrupts and doorbells ionic: Add basic adminq support ionic: Add adminq action ionic: Add notifyq support ionic: Add the basic NDO callbacks for netdev support ionic: Add management of rx filters ionic: Add Rx filter and rx_mode ndo support ionic: Add async link status check and basic stats ionic: Add initial ethtool support ionic: Add Tx and Rx handling ionic: Add netdev-event handling ionic: Add driver stats ionic: Add RSS support ionic: Add coalesce and other features ionic: Add basic devlink interface .../networking/device_drivers/index.rst | 1 + .../device_drivers/pensando/ionic.rst | 64 + MAINTAINERS | 8 + drivers/net/ethernet/Kconfig | 1 + drivers/net/ethernet/Makefile | 1 + drivers/net/ethernet/pensando/Kconfig | 32 + drivers/net/ethernet/pensando/Makefile | 6 + drivers/net/ethernet/pensando/ionic/Makefile | 8 + drivers/net/ethernet/pensando/ionic/ionic.h | 74 + .../net/ethernet/pensando/ionic/ionic_bus.h | 16 + .../ethernet/pensando/ionic/ionic_bus_pci.c | 290 ++ .../ethernet/pensando/ionic/ionic_debugfs.c | 279 ++ .../ethernet/pensando/ionic/ionic_debugfs.h | 38 + .../net/ethernet/pensando/ionic/ionic_dev.c | 535 ++++ .../net/ethernet/pensando/ionic/ionic_dev.h | 284 ++ .../ethernet/pensando/ionic/ionic_devlink.c | 93 + .../ethernet/pensando/ionic/ionic_devlink.h | 14 + .../ethernet/pensando/ionic/ionic_ethtool.c | 774 +++++ .../ethernet/pensando/ionic/ionic_ethtool.h | 9 + .../net/ethernet/pensando/ionic/ionic_if.h | 2552 +++++++++++++++++ .../net/ethernet/pensando/ionic/ionic_lif.c | 2262 +++++++++++++++ .../net/ethernet/pensando/ionic/ionic_lif.h | 270 ++ .../net/ethernet/pensando/ionic/ionic_main.c | 553 ++++ .../net/ethernet/pensando/ionic/ionic_regs.h | 133 + .../ethernet/pensando/ionic/ionic_rx_filter.c | 143 + .../ethernet/pensando/ionic/ionic_rx_filter.h | 35 + .../net/ethernet/pensando/ionic/ionic_stats.c | 333 +++ .../net/ethernet/pensando/ionic/ionic_stats.h | 53 + .../net/ethernet/pensando/ionic/ionic_txrx.c | 879 ++++++ .../net/ethernet/pensando/ionic/ionic_txrx.h | 15 + 30 files changed, 9755 insertions(+) create mode 100644 Documentation/networking/device_drivers/pensando/ionic.rst create mode 100644 drivers/net/ethernet/pensando/Kconfig create mode 100644 drivers/net/ethernet/pensando/Makefile create mode 100644 drivers/net/ethernet/pensando/ionic/Makefile create mode 100644 drivers/net/ethernet/pensando/ionic/ionic.h create mode 100644 drivers/net/ethernet/pensando/ionic/ionic_bus.h create mode 100644 drivers/net/ethernet/pensando/ionic/ionic_bus_pci.c create mode 100644 drivers/net/ethernet/pensando/ionic/ionic_debugfs.c create mode 100644 drivers/net/ethernet/pensando/ionic/ionic_debugfs.h create mode 100644 drivers/net/ethernet/pensando/ionic/ionic_dev.c create mode 100644 drivers/net/ethernet/pensando/ionic/ionic_dev.h create mode 100644 drivers/net/ethernet/pensando/ionic/ionic_devlink.c create mode 100644 drivers/net/ethernet/pensando/ionic/ionic_devlink.h create mode 100644 drivers/net/ethernet/pensando/ionic/ionic_ethtool.c create mode 100644 drivers/net/ethernet/pensando/ionic/ionic_ethtool.h create mode 100644 drivers/net/ethernet/pensando/ionic/ionic_if.h create mode 100644 drivers/net/ethernet/pensando/ionic/ionic_lif.c create mode 100644 drivers/net/ethernet/pensando/ionic/ionic_lif.h create mode 100644 drivers/net/ethernet/pensando/ionic/ionic_main.c create mode 100644 drivers/net/ethernet/pensando/ionic/ionic_regs.h create mode 100644 drivers/net/ethernet/pensando/ionic/ionic_rx_filter.c create mode 100644 drivers/net/ethernet/pensando/ionic/ionic_rx_filter.h create mode 100644 drivers/net/ethernet/pensando/ionic/ionic_stats.c create mode 100644 drivers/net/ethernet/pensando/ionic/ionic_stats.h create mode 100644 drivers/net/ethernet/pensando/ionic/ionic_txrx.c create mode 100644 drivers/net/ethernet/pensando/ionic/ionic_txrx.h -- 2.17.1
