The SFC9000-family controllers have firmware to manage all board peripherals including temperature, heat sink continuity and voltage sensors. The firmware reports sensor alarms, which we log, and will shut down the board if necessary. Some users may want to monitor their boards more closely, so add an hwmon driver that exposes all sensors reported by the firmware. Move efx_mcdi_sensor_event() into the new file so it can share the array of sensor labels with the hwmon driver. Signed-off-by: NBen Hutchings <bhutchings@solarflare.com>

Interrupts are normally generated by the event queues, moderated by timers. However, they may also be triggered by detection of a 'fatal' error condition (e.g. memory parity error) or by the host writing to certain CSR fields as part of a self-test. The IRQ level/index used for these on Falcon rev B0 and Siena is set by the KER_INT_LEVE_SEL field and cached by the driver in efx_nic::fatal_irq_level. Since this value is also relevant to self-tests rename the field to just 'irq_level'. Avoid unnecessary cache traffic by using a per-channel 'last_irq_cpu' field and only writing to the per-controller field when the interrupt matches efx_nic::irq_level. Remove the volatile qualifier and use ACCESS_ONCE in the places we read these fields. Signed-off-by: NBen Hutchings <bhutchings@solarflare.com>

This reverts commit 63695459 in drivers/net/ethernet/sfc/falcon.c. Unlike the INT_ISR0 register on later controller revisions, the NET_IVEC_INT_Q bits written to memory are only ever set for interrupting event queues, not for any other interrupt sources. By definition there can only be one legacy interrupt handler per function, so there is no need to worry about detecting a fatal interrupt more than once.

We cannot safely assume that the NAPI handler will complete within the 20 ms that we allow for the event self-test. The handler may be deferred for longer than this, particularly on realtime kernels. Instead, check whether either an event has been handled or (as in the old failure path) whether an interrupt has been received and an event has been delivered but not yet handled. Use napi_disable() to synchronize with the NAPI handler before checking, since it will clear events before updating eventq_read_ptr. Remove the test result chan.N.eventq.poll, since it is not an error if the NAPI handler does not run during the test. Signed-off-by: NBen Hutchings <bhutchings@solarflare.com>

We currently assume that the timer quantum for Siena is 5 us, the same as for Falcon. This is not correct; timer ticks are generated on a rota which takes a minimum of 768 cycles (each event delivery or other timer change will delay it by 3 cycles). The timer quantum should be 6.144 or 3.072 us depending on whether turbo mode is active. Replace EFX_IRQ_MOD_RESOLUTION with a timer_quantum_ns field in struct efx_nic, initialised by the efx_nic_type::probe function. While we're at it, replace EFX_IRQ_MOD_MAX with a timer_period_max field in struct efx_nic_type. Signed-off-by: NBen Hutchings <bhutchings@solarflare.com>

The netif_dbg() macro is defined in <linux/netdevice.h>. If the DEBUG macro is defined, it logs a message at 'debug' level, otherwise it does nothing. In net_driver.h we define DEBUG if EFX_ENABLE_DEBUG is defined, but this is too late for those source files that already got a definition of netif_dbg() by including <linux/netdevice.h> Get rid of EFX_ENABLE_DEBUG, and only define and test DEBUG. In mtd.c, we do not use DEBUG as a condition flag but are forced to use the DEBUG macro-function from <linux/mtd/mtd.h>. Undefine DEBUG before including it.

Both implementations of efx_nic_type::reconfigure_mac operation push the multicast hash filter to the hardware. It is therefore redundant to call efx_nic_type::push_multicast_hash as well. efx_mcdi_mac_reconfigure() also uses this operation, but the implementation for Siena just uses MCDI anyway. Merge that into efx_mcdi_mac_reconfigure(). Signed-off-by: NBen Hutchings <bhutchings@solarflare.com>

No NICs need to switch efx_mac_operations at run-time, and the MAC operations are fairly closely bound to NIC types. Move efx_mac_operations::reconfigure to efx_nic_type::reconfigure_mac and efx_mac_operations::check_fault fo efx_nic_type::check_mac_fault. Change callers to call through efx->type or directly if the NIC type is known. Remove efx_mac_operations::update_stats. The implementations for Falcon used to fetch MAC statistics synchronously and this was used by efx_register_netdev() to clear statistics after running self-tests. However, it now only converts statistics that have already been fetched (and that only for Falcon), and the call from efx_register_netdev() has no effect.

efx_nic::stats_lock is used to serialise stats updates, but each reader was dropping it before it finished reading efx_nic::mac_stats. If there were concurrent stats reads using procfs, or one using procfs and one using ethtool, an update could race with a read. On a 32-bit system, the reader could see word-tearing of 64-bit stats (32 bits of the old value and 32 bits of the new). Signed-off-by: NBen Hutchings <bhutchings@solarflare.com>

When the MC reboots, either as part of a firmware upgrade or due to a bug, it attempts to complete (with an error) any requests that were outstanding before the reboot. Since there is an inherent race condition in checking this, it will also write to a status word in shared memory. If we look at each of these separately, we may detect each reboot twice, resulting in a spurious command failure after a firmware upgrade or frustrating recovery from a firmware bug. Instead, if a request completion indicates a reboot, we must poll and clear the status word. This bug was previously masked by use of an incorrect address for the status word. Fix that, using the definition now included in mcdi_pcol.h. Signed-off-by: NBen Hutchings <bhutchings@solarflare.com>

By the time we look at the MAC address in efx_probe_port(), either the driver or the firmware has already validated the board configuration. The possibility of having an invalid MAC address just isn't worth considering. It certainly isn't worth having a compile-time option for this.

All drivers that support modification of the RX flow hash indirection table initialise it in the same way: RX rings are assigned to table entries in rotation. Make that default policy explicit by having them call a ethtool_rxfh_indir_default() function. In the ethtool core, add support for a zero size value for ETHTOOL_SRXFHINDIR, which resets the table to this default.

Add a new ethtool operation (get_rxfh_indir_size) to get the indirectional table size. Use this to validate the user buffer size before calling get_rxfh_indir or set_rxfh_indir. Use get_rxnfc to get the number of RX rings, and validate the contents of the new indirection table before calling set_rxfh_indir. Remove this validation from drivers.
