sfc: Add X4 PF support

2024-09-11T23:02:21Z

Add X4 series. Most functionality is the same as previous EF10 nics but enough is different to warrant a new nic type struct and revision; for example legacy interrupts and SRIOV are not supported. Most removed features will be re-added later as new implementations.

sfc: Remove siena_nic_data and stats

2023-07-28T08:54:17Z

These are no longer used, and the two Siena specific functions are no longer present in sfc.ko. Signed-off-by: Martin Habets Acked-by: Edward Cree Signed-off-by: David S. Miller

sfc: Remove falcon references

2023-07-28T08:54:16Z

Siena was using functions from the Falcon architecture. These start with the efx_farch prefix. Now that both of these are in separate modules the references are no longer used in the sfc.ko module. Signed-off-by: Martin Habets Acked-by: Edward Cree Signed-off-by: David S. Miller

sfc: Disable Siena support

2022-05-04T10:18:08Z

Disable the build of Siena code until later in this patch series. Prevent sfc.ko from binding to Siena NICs. efx_init_sriov/efx_fini_sriov is only used for Siena. Remove calls to those. Signed-off-by: Martin Habets Signed-off-by: David S. Miller

sfc: de-indirect TSO handling

2020-09-12T00:15:22Z

Remove the tx_queue->handle_tso function pointer, and just use tx_queue->tso_version to decide which function to call, thus removing an indirect call from the fast path. Instead of passing a tso_v2 flag to efx_mcdi_tx_init(), set the desired tx_queue->tso_version before calling it. In efx_mcdi_tx_init(), report back failure to obtain a TSOv2 context by setting tx_queue->tso_version to 0, which will cause the TX path to use the GSO-based fallback.

sfc: remove duplicate declaration of efx_enqueue_skb_tso()

2020-06-30T20:09:09Z

Define it in nic_common.h, even though the ef100 driver will have a different implementation backing it (actually a WARN_ON_ONCE as it should never get called by ef100. But it needs to still exist because common TX path code references it). Signed-off-by: Edward Cree Signed-off-by: David S. Miller

sfc: commonise drain event handling

2020-06-30T00:37:49Z

Avoids a call from generic MCDI code into ef10.c. Signed-off-by: Edward Cree Signed-off-by: David S. Miller

sfc: split up nic.h

2020-06-30T00:37:48Z

The new nic_common.h contains the inlines for NIC-type function dispatch, declarations for NIC-generic functions in nic.c, and other similar NIC- generic functionality. Retained in nic.h are NIC-specific declarations such as the siena and ef10 nic_data structs and various farch functions. The EF100 driver will thus include nic_common.h but not nic.h.

sfc: refactor EF10 stats handling

2020-06-30T00:37:48Z

Separate the generation-count handling from the format conversion, to make it easier to re-use both for EF100. Signed-off-by: Edward Cree Signed-off-by: David S. Miller

sfc: move rx_rss_context_exclusive into struct efx_mcdi_filter_table

2020-05-11T20:31:49Z

It's both set and used solely by mcdi_filters.c, so there's no reason for it to be in ef10-specific nic_data. Signed-off-by: Edward Cree Signed-off-by: David S. Miller
