2019-10-22dynamic_debug: provide dynamic_hex_dump stubArnd Bergmann
The ionic driver started using dymamic_hex_dump(), but that is not always defined: drivers/net/ethernet/pensando/ionic/ionic_main.c:229:2: error: implicit declaration of function 'dynamic_hex_dump' [-Werror,-Wimplicit-function-declaration] Add a dummy implementation to use when CONFIG_DYNAMIC_DEBUG is disabled, printing nothing. Fixes: 938962d55229 ("ionic: Add adminq action") Signed-off-by: Arnd Bergmann <arnd@arndb.de> Acked-by: Shannon Nelson <snelson@pensando.io> Signed-off-by: Jakub Kicinski <jakub.kicinski@netronome.com>
2019-10-07ionic: fix stats memory dereferenceShannon Nelson
When the netdev is down, the queues and their debug stats do not exist, so don't try using a pointer to them when when printing the ethtool stats. Fixes: e470355bd96a ("ionic: Add driver stats") Signed-off-by: Shannon Nelson <snelson@pensando.io> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-10-01ionic: select CONFIG_NET_DEVLINKArnd Bergmann
When no other driver selects the devlink library code, ionic produces a link failure: drivers/net/ethernet/pensando/ionic/ionic_devlink.o: In function `ionic_devlink_alloc': ionic_devlink.c:(.text+0xd): undefined reference to `devlink_alloc' drivers/net/ethernet/pensando/ionic/ionic_devlink.o: In function `ionic_devlink_register': ionic_devlink.c:(.text+0x71): undefined reference to `devlink_register' Add the same 'select' statement that the other drivers use here.

2019-09-22ionic: Fix an error code in ionic_lif_alloc()Dan Carpenter
We need to set the error code on this path. Otherwise it probably results in a NULL dereference down the line.

2019-09-19ionic: Remove unnecessary ternary operator in ionic_debugfs_add_identNathan Chancellor
clang warns: ../drivers/net/ethernet/pensando/ionic/ionic_debugfs.c:60:37: warning: expression result unused [-Wunused-value] ionic, &identity_fops) ? 0 : -EOPNOTSUPP; ^~~~~~~~~~~ 1 warning generated. The return value of debugfs_create_file does not need to be checked [1] and the function returns void so get rid of the ternary operator, it is unnecessary.

2019-09-05ionic: Add coalesce and other featuresShannon Nelson
Interrupt coalescing, tunable copybreak value, and tx timeout. Signed-off-by: Shannon Nelson <snelson@pensando.io> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-09-05ionic: Add RSS supportShannon Nelson
Add code to manipulate through ethtool the RSS configuration used by the NIC. Signed-off-by: Shannon Nelson <snelson@pensando.io> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-09-05ionic: Add driver statsShannon Nelson
Add in the detailed statistics for ethtool -S that the driver keeps as it processes packets. Display of the additional debug statistics can be enabled through the ethtool priv-flags feature. Signed-off-by: Shannon Nelson <snelson@pensando.io> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-09-05ionic: Add netdev-event handlingShannon Nelson
When the netdev gets a new name from userland, pass that name down to the NIC for internal tracking. Signed-off-by: Shannon Nelson <snelson@pensando.io> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-09-05ionic: Add Tx and Rx handlingShannon Nelson
Add both the Tx and Rx queue setup and handling. The related stats display comes later. Instead of using the generic napi routines used by the slow-path commands, the Tx and Rx paths are simplified and inlined in one file in order to get better compiler optimizations.

2019-09-05ionic: Add initial ethtool supportShannon Nelson
Add in the basic ethtool callbacks for device information and control. Signed-off-by: Shannon Nelson <snelson@pensando.io> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-09-05ionic: Add async link status check and basic statsShannon Nelson
Add code to handle the link status event, and wire up the basic netdev hardware stats. Signed-off-by: Shannon Nelson <snelson@pensando.io> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-09-05ionic: Add Rx filter and rx_mode ndo supportShannon Nelson
Add the Rx filtering and rx_mode NDO callbacks. Also add the deferred work thread handling needed to manage the filter requests outside of the netif_addr_lock spinlock. Signed-off-by: Shannon Nelson <snelson@pensando.io> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-09-05ionic: Add management of rx filtersShannon Nelson
Set up the infrastructure for managing Rx filters. We can't ask the hardware for what filters it has, so we keep a local list of filters that we've pushed into the HW. Signed-off-by: Shannon Nelson <snelson@pensando.io> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-09-05ionic: Add the basic NDO callbacks for netdev supportShannon Nelson
Set up the initial NDO structure and callbacks for netdev to use, and register the netdev. This will allow us to do a few basic operations on the device, but no traffic yet. Signed-off-by: Shannon Nelson <snelson@pensando.io> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-09-05ionic: Add notifyq supportShannon Nelson
The AdminQ is fine for sending messages and requests to the NIC, but we also need to have events published from the NIC to the driver. The NotifyQ handles this for us, using the same interrupt as AdminQ. Signed-off-by: Shannon Nelson <snelson@pensando.io> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-09-05ionic: Add adminq actionShannon Nelson
Add AdminQ specific message requests and completion handling. Signed-off-by: Shannon Nelson <snelson@pensando.io> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-09-05ionic: Add basic adminq supportShannon Nelson
Most of the NIC configuration happens through the AdminQ message queue. NAPI is used for basic interrupt handling and message queue management. These routines are set up to be shared among different types of queues when used in slow-path handling. Signed-off-by: Shannon Nelson <snelson@pensando.io> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-09-05ionic: Add interrupts and doorbellsShannon Nelson
The ionic interrupt model is based on interrupt control blocks accessed through the PCI BAR. Doorbell registers are used by the driver to signal to the NIC that requests are waiting on the message queues. Interrupts are used by the NIC to signal to the driver that answers are waiting on the completion queues. Signed-off-by: Shannon Nelson <snelson@pensando.io> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-09-05ionic: Add basic lif supportShannon Nelson
The LIF is the Logical Interface, which represents the external connections. The NIC can multiplex many LIFs to a single port, but in most setups, LIF0 is the primary control for the port. Signed-off-by: Shannon Nelson <snelson@pensando.io> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-09-05ionic: Add port management commandsShannon Nelson
The port management commands apply to the physical port associated with the PCI device, which might be shared among several logical interfaces. Signed-off-by: Shannon Nelson <snelson@pensando.io> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-09-05ionic: Add hardware init and device commandsShannon Nelson
The ionic device has a small set of PCI registers, including a device control and data space, and a large set of message commands. Also adds new DEVLINK_INFO_VERSION_GENERIC tags for ASIC_ID, ASIC_REV, and FW. Signed-off-by: Shannon Nelson <snelson@pensando.io> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-09-05ionic: Add basic framework for IONIC Network device driverShannon Nelson
This patch adds a basic driver framework for the Pensando IONIC network device. There is no functionality right now other than the ability to load and unload. Signed-off-by: Shannon Nelson <snelson@pensando.io> Signed-off-by: David S. Miller <davem@davemloft.net>
