sfc: Add support for Solarflare SFC9100 family

2013-08-29T18:19:29+00:00

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.

sfc: Make most filter operations NIC-type-specific

2013-08-22T18:25:57+00:00

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

2013-08-21T19:19:05+00:00

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.

sfc: Collect all MCDI port functions into mcdi_port.c

2013-08-21T18:43:03+00:00

Collect together MCDI port functions from mcdi.c, mcdi_mac.c,
mcdi_phy.c and siena.c.  Rename the 'siena' functions accordingly.

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

2013-08-21T15:35:20+00:00

In particular, fold in the whole of falcon_xmac.c.

Drop some entirely unused definitions.

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

2012-11-01T15:35:18+00:00

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

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

2012-02-16T00:25:13+00:00

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.

sfc: Add hwmon driver for boards using SFC9000-family controllers

2012-01-27T00:10:53+00:00

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.

Moves the Solarflare drivers into drivers/net/ethernet/sfc/ and
make the necessary Kconfig and Makefile changes.
