2012-02-16sfc: Add SR-IOV back-end support for SFC9000 familyBen Hutchings13-26/+2192
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 <bhutchings@solarflare.com>
2012-02-16sfc: Allocate SRAM between buffer table and descriptor caches at init timeBen Hutchings6-14/+50
Each port has a block of 64-bit SRAM that is divided between buffer table and descriptor cache regions at initialisation time. Currently we use a fixed allocation, but it needs to be changed to support larger numbers of queues. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>
2012-02-16sfc: Pass NIC structure into efx_wanted_parallelism()Ben Hutchings1-4/+4
This lets us identify the NIC affected in case of failure, and will be necessary to adjust for SR-IOV constraints. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>
2012-02-16sfc: Add support for 'extra' channel typesBen Hutchings3-108/+239
Abstract some of the channel operations to allow for 'extra' channels that do not have RX or TX queues. - Try to assign a channel to each extra channel type that is enabled for the NIC, but gracefully degrade if we can't allocate sufficient MSI-X vectors - Allow each extra channel type to generate its own channel name - Allow channel types to disable reallocation and reinitialisation of their channels Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>

2012-02-16sfc: Disable flow control during flushesSteve Hodgson3-0/+9
The TX DMA engine issues upstream read requests when there is room in the TX FIFO for the completion. However, the fetches for the rest of the packet might be delayed by any back pressure. Since a flush must wait for an EOP, the entire flush may be delayed by back pressure. Mitigate this by disabling flow control before the flushes are started. Since PF and VF flushes run in parallel introduce fc_disable, a reference count of the number of flushes outstanding. The same principle could be applied to Falcon, but that would bring with it its own testing. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>
2012-02-16sfc: Generalise event generation to cover VF-owned event queuesBen Hutchings2-6/+7
For SR-IOV we will need to send events to event queues that belong to VFs serviced by other drivers. Change the parameters of efx_generate_event() to allow this and declare it extern. While we're at it, remove the existing declaration under the wrong name efx_nic_generate_event(). Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>

2012-02-16sfc: Leave interrupts and event queues enabled whenever we canBen Hutchings4-318/+308
When SR-IOV is enabled we may receive FLR (Function-Level Reset) events, associated queue flush events and requests from VF drivers at any time. Therefore we need to keep event queues and interrupts enabled whenever possible. Currently we stop interrupt-driven event processing before flushing RX and TX queues; efx_nic_flush_queues() then polls event queues for flush events and discards any others it finds. Change it to work with the regular event handling functions. Currently efx_start_channel() fills RX queues synchronously when a device is brought up. This could now race with NAPI, so change it to send fill events. This was almost entirely written by Steve Hodgson, formerly shodgson@solarflare.com.

2012-02-16sfc: Correct MAC filter bitfield definitionsBen Hutchings1-10/+10
The RMFT_DEST_MAC and TMFT_SRC_MAC register fields were previously documented as 44 bits wide, whereas a MAC address has 48 bits. Thankfully the hardware uses the correct width and the driver has used separate definitions that divide each of these into 32-bit and 16-bit fields. Fix the initial definitions for these fields and rewrite the latter definitions to use them. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>
2012-02-16sfc: Add support for TX MAC filtersBen Hutchings2-5/+72
On Siena each TX queue can be configured to send only packets for which there is a TX MAC filter that matches the source MAC address, queue ID, and optionally VID. This will be used to implement the 'spoofchk' feature for SR-IOV virtual functions. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>
2012-02-16sfc: Add support for configuring RX unicast/multicast default filtersBen Hutchings3-47/+214
On Siena all received packets that don't match a more specific filter will match the unicast or multicast default filter. Currently we leave these set to the default values (RSS with base queue number of 0). Allow them to be reconfigured to select a single RX queue. These default filters are programmed through the FILTER_CTL register, but we represent them internally as an additional table of size 2. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>
