* sfc: Store port number in net_device::dev_idBen Hutchings2010-06-03
| | | | | | | This exposes the port number to userland through sysfs. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* sfc: Get port number from CS_PORT_NUM, not PCI function numberBen Hutchings2010-06-03
| | | | | | | | | | | | A single shared memory region used to communicate with firmware is mapped into both PCI PFs of the SFC9020 and SFL9021. Drivers must be able to identify which port they are addressing in order to use the correct sub-region. Currently we use the PCI function number, but the PCI address may be virtualised. Use the CS_PORT_NUM register field defined for just this purpose. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* sfc: Create multiple TX queuesBen Hutchings2010-04-28
| | | | | | | | | | | | Create a core TX queue and 2 hardware TX queues for each channel. If separate_tx_channels is set, create equal numbers of RX and TX channels instead. Rewrite the channel and queue iteration macros accordingly. Eliminate efx_channel::used_flags as redundant. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S.

| | | | | | | | There is no need for this to be unsigned long; make it unsigned int. It does need a line in kernel-doc, so add that. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>

* sfc: Handle serious errors in exactly one interrupt handlerSteve Hodgson2010-04-28
| | | | | | | | | | | | | 'Fatal' errors set an interrupt flag associated with a specific event queue; only read the syndrome vector if we see that queue's flag set (legacy interrupts) or in the interrupt handler for that queue (MSI). Do not ignore an interrupt if the fatal error flag is set but specific error flags are all zero. Even if we don't schedule a reset, we must respect the queue mask and rearm the appropriate event queues. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S.

* sfc: Replace PHY MDIO test with an 'alive' testBen Hutchings2010-02-03
| | | | | | | | | | | | | | | | SFC9000-family boards do not all use MDIO PHYs, so we need a different test for PHY aliveness. Introduce a PHY operation test_alive(). For PHYs attached to Falcon, use a common implementation based on the existing PHY MDIO test. For PHYs managed through MCDI, use the appropriate MCDI request. Change test name in ethtool from 'core mdio' to 'phy alive'. Rename test_results::mdio to phy_alive and test_results::phy to phy_ext.

* sfc: Move PHY software state initialisation from init() into probe()Steve Hodgson2009-12-23
| | | | | | | | | | | | This prevents efx->link_advertising from being blatted during a reset. The phy_short_reach sysfs node is now destroyed later in the port shutdown process, so check for STATE_RUNNING after acquiring the rtnl_lock (just like in set_phy_flash_cfg).

* sfc: Extend MTD driver for use with new NICsBen Hutchings2009-11-29
| | | | | | | | | | | In new NICs flash is managed by firmware and we will use high-level operations on partitions rather than direct SPI commands.

* sfc: Refactor link configurationBen Hutchings2009-11-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Refactor PHY, MAC and NIC configuration operations so that the existing link configuration can be re-pushed with: efx->phy_op->reconfigure(efx); efx->mac_op->reconfigure(efx); and a new configuration with: efx->nic_op->reconfigure_port(efx); (plus locking and error-checking). We have not held the link settings in software (aside from flow control), and have relied on asking the hardware what they are. This is a problem because in some cases the hardware may no longer be in a state to tell us. In particular, if an entire multi-port board is reset through one port, the driver bindings to other ports have no chance to save settings before recovering. We only actually need to keep track of the autonegotiation settings, so add an ethtool advertising mask to struct efx_nic, initialise it in PHY init and update it as necessary. Remove now-unneeded uses of efx_phy_op::{get,set}_settings() and struct ethtool_cmd. Much of this was done by Steve Hodgson <shodgson@solarflare.com>.

* sfc: Always start Falcon using the XMACSteve Hodgson2009-11-29

* sfc: Simplify PHY pollingSteve Hodgson2009-11-29
| | | | | | | | | | | | | | Falcon can generate events for LASI interrupts from the PHY, but in practice we have never implemented this in reference designs. Instead we have polled, inserted the appropriate events, and then handled the events later. This is a waste of time and code. Instead, make PHY poll functions update the link state synchronously and report whether it changed. We can still make use of the LASI registers as a shortcut on the SFT9001.

* sfc: Change MAC promiscuity and multicast hash at the same timeBen Hutchings2009-11-26
| | | | | | | | | | | | | | | | | From: Steve Hodgson <shodgson@solarflare.com> Currently we can set multicast hash immediately (in atomic context) but must delay setting MAC promiscuity. There is not that much point in deferring one but not the other, and setting the multicast hash on Siena will involve a firmware request. So process them both in efx_mac_work(). Also, set the broadcast bit in the multicast hash in efx_set_multicast_list(), since this is required for both Falcon and Siena.

* sfc: Simplify XMAC link pollingBen Hutchings2009-11-26
| | | | | | | | | | | | | | | | | | | | | | | | From: Steve Hodgson <shodgson@solarflare.com> Only the XMAC on Falcon needs help from the driver to poll and reset the MAC-PHY link (XAUI); GMII is a simple parallel bus and on later NICs firmware takes care of the XAUI link. Also, an XMAC interrupt currently schedules a work item which simply clears a flag (efx_nic::mac_up) to be checked by the regular monitor (or the next link reconfiguration, if that is sooner). Rename the flag to xmac_poll_required, changing its sense. Remove the needless indirection and just set the flag immediately. Call falcon_xmac_poll() directly where required. Add a new generic operation mac_op::check_fault to check the link outside of regular monitoring, as required during self-tests. (Note that this leaves us with an unused work item, but we will immediately have another use for it.) Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S.

* sfc: Split MAC stats DMA initiation and completionBen Hutchings2009-11-26
| | | | | | | | | | | | | | | From: Steve Hodgson <shodgson@solarflare.com> Currently we initiate MAC stats DMA and busy-wait for completion when stats are requested. We can improve on this with a periodic timer to initiate and poll for stats, and opportunistically poll when stats are requested. Since efx_nic::stats_disable_count and efx_stats_{disable,enable}() are Falcon-specific, rename them and move them accordingly.

| | | | | | | | | | | efx_board::init_leds was introduced as a second stage of initialisation because of the inter-dependency between the board and PHY. We want to move board initialisation into NIC probing, which is too early to use MDIO, so SFN4111T initialisation also needs to be split.
