sfc: Enable VF's via a write to the sysfs file sriov_numvfs

2015-05-09T20:16:46Z

This patch adds support for the use of sriov_configure on EF10 to enable Virtual Functions while the driver is loaded. Signed-off-by: Shradha Shah Signed-off-by: David S. Miller

sfc: Own header for nic-specific sriov functions, single instance of netdev_ops and sriov removed from Falcon code

2015-05-09T20:16:46Z

By putting all the efx_{siena,ef10}_sriov_* declarations in {siena,ef10}_sriov.h, ensure they cannot be called from nic-generic code. Also fixes up an instance of this, where mcdi.c was calling efx_siena_sriov_flr. The single instance of netdev_ops should call general high level functions that can then call something adapter specific in efx_nic_type. We should only do adapter specialisation via efx_nic_type. Removal of sriov functionality from the Falcon code means that tests are needed for the presence of some callbacks. Signed-off-by: Shradha Shah Signed-off-by: David S. Miller

sfc: Add support for Solarflare SFC9100 family

2013-08-29T18:19:29Z

This adds support for the EF10 network controller architecture and the SFC9100 family, starting with SFC9120 'Farmingdale', and bumps the driver version to 4.0. New features in the SFC9100 family include: - Flexible allocation of internal resources to PCIe physical and virtual functions under firmware control - RX event merging to reduce DMA writes at high packet rates - Integrated RX timestamping - PIO buffers for lower TX latency - Firmware-driven data path that supports additional offload features and filter types - Delivery of packets between functions and to multiple recipients, allowing firmware to implement a vswitch - Multiple RX flow hash (RSS) contexts with their own hash keys and indirection tables - 40G MAC (single port only) ...not all of which are enabled in this initial driver or the initial firmware release. Much of the new code is by Jon Cooper. Signed-off-by: Ben Hutchings

sfc: Make most filter operations NIC-type-specific

2013-08-22T18:25:57Z

Aside from accelerated RFS, there is almost nothing that can be shared between the filter table implementations for the Falcon architecture and EF10. Move the few shared functions into efx.c and rx.c and the rest into farch.c. Introduce efx_nic_type operations for the implementation and inline wrapper functions that call these.

sfc: Move and rename Falcon/Siena common NIC operations

2013-08-21T19:19:05Z

Add efx_nic_type operations for the many efx_nic functions that need to be implemented different on EF10. For now, change most of the existing efx_nic_*() functions into inline wrappers. As a later step, we may be able to improve branch prediction for operations used on the fast path by copying the pointers into each queue/channel structure. Move the Falcon/Siena implementations to new file farch.c and rename the functions and static data to use a prefix of 'efx_farch_'. Move efx_may_push_tx_desc() to nic.h, as the EF10 TX code will also use it. Signed-off-by: Ben Hutchings

sfc: Collect all MCDI port functions into mcdi_port.c

2013-08-21T18:43:03Z

Collect together MCDI port functions from mcdi.c, mcdi_mac.c, mcdi_phy.c and siena.c. Rename the 'siena' functions accordingly. Signed-off-by: Ben Hutchings

sfc: Move more Falcon-specific code and definitions into falcon.c

2013-08-21T15:35:20Z

In particular, fold in the whole of falcon_xmac.c. Drop some entirely unused definitions. Signed-off-by: Ben Hutchings

ptp: Enable clock drivers along with associated net/PHY drivers

2012-11-01T15:35:18Z

Where a PTP clock driver is associated with a net or PHY driver, it should be enabled automatically whenever that driver is enabled. Therefore: - Make PTP clock drivers select rather than depending on PTP_1588_CLOCK - Remove separate boolean options for PTP clock drivers that are built as part of net driver modules. (This also fixes cases where the PTP subsystem is wrongly forced to be built-in.) - Set 'default y' for PTP clock drivers that depend on specific net drivers but are built separately Signed-off-by: Ben Hutchings Signed-off-by: David S. Miller

sfc: Add support for IEEE-1588 PTP

2012-09-19T01:54:12Z

Add PTP IEEE-1588 support and make accesible via the PHC subsystem. This work is based on prior code by Andrew Jackson Signed-off-by: Stuart Hodgson [bwh: - Add byte order conversion in efx_ptp_send_times() - Simplify conversion of PPS event times - Add the built-in vs module check to CONFIG_SFC_PTP dependencies] Signed-off-by: Ben Hutchings

sfc: Add SR-IOV back-end support for SFC9000 family

2012-02-16T00:25:13Z

On the SFC9000 family, each port has 1024 Virtual Interfaces (VIs), each with an RX queue, a TX queue, an event queue and a mailbox register. These may be assigned to up to 127 SR-IOV virtual functions per port, with up to 64 VIs per VF. We allocate an extra channel (IRQ and event queue only) to receive requests from VF drivers. There is a per-port limit of 4 concurrent RX queue flushes, and queue flushes may be initiated by the MC in response to a Function Level Reset (FLR) of a VF. Therefore, when SR-IOV is in use, we submit all flush requests via the MC. The RSS indirection table is shared with VFs, so the number of RX queues used in the PF is limited to the number of VIs per VF. This is almost entirely the work of Steve Hodgson, formerly shodgson@solarflare.com. Signed-off-by: Ben Hutchings
