2008-12-12sfc: Treat probe as unsuccessful if it scheduled a resetSteve Hodgson1-2/+11
From: Steve Hodgson <[email protected]> efx_pci_probe_main() can return success despite a reset being scheduled. Catch this and retry or abort probe depending on the reset type. Signed-off-by: Ben Hutchings <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2008-12-12sfc: Use model numbers for PHY type namesBen Hutchings3-5/+5
Some of the PHY type names are overly generic. Change them to include the model numbers of the PHYs they represent. Correct the model number reference at the top of xfp_phy.c. Signed-off-by: Ben Hutchings <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2008-12-12sfc: Use mutex_lock_interruptible() for ethtool EEPROM accessBen Hutchings1-2/+8
ethtool must contend with the MTD driver for the SPI bus lock, which may carry out long operations such as flash erase. Allow it to be interrupted while waiting. Signed-off-by: Ben Hutchings <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2008-12-12sfc: Specify a meaningful component for loopback RX-side and PHY testsBen Hutchings1-6/+8
Our ethtool self-test result names each begin with a component name. For some results this is "port0", which is not very meaningful. Change that to "rx" or "phy" as appropriate. Signed-off-by: Ben Hutchings <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2008-12-12sfc: Remove leading spacesBen Hutchings1-2/+2

2008-12-12sfc: Add support for SFN4111TBen Hutchings7-35/+150
Add support code for the SFN4111T 100/1000/10GBASE-T reference design, based in part on the existing code for the SFE4001. Signed-off-by: Ben Hutchings <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2008-12-12sfc: Add support for Solarflare 10Xpress SFT9001Ben Hutchings8-105/+467
Add type codes for the new PHY and rename the SFX7101 type code. Add definition of clause 22 extension MMD. Adapt the 10Xpress SFX7101 code to support the SFT9001 as well. Clean up register definitions. Signed-off-by: Ben Hutchings <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2008-12-12sfc: Rework MAC, PHY and board event handlingBen Hutchings9-114/+111
From: Steve Hodgson <[email protected]> MAC, PHY and board events may be separately enabled and signalled. Our current arrangement of chaining the polling functions can result in events being missed. Change them to be more independent. Signed-off-by: Ben Hutchings <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2008-12-12sfc: Implement auto-negotiationBen Hutchings9-154/+472
Add infrastructure for auto-negotiation of speed, duplex and flow control. When using 10Xpress, auto-negotiate flow control. While we're at it, clean up the code to warn when partner is not 10GBASE-T capable. Signed-off-by: Ben Hutchings <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2008-12-12sfc: Add support for sub-10G speedsBen Hutchings16-321/+699
The SFC4000 has a separate MAC for use at sub-10G speeds. Introduce an efx_mac_operations structure with implementations for the two MACs. Switch between the MACs as necessary. PHY settings are independent of the MAC, so add get_settings() and set_settings() to efx_phy_operations. Also add macs field to indicate which MACs the PHY is connected to. Signed-off-by: Ben Hutchings <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2008-12-12sfc: Clean up MDIO flag settingBen Hutchings2-59/+32
We often want to set or clear a flag in an MDIO register, but avoid writing if no change is required since this can have side-effects. Encapsulate this in a function, mdio_clause45_set_flag(). Signed-off-by: Ben Hutchings <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2008-12-12sfc: Clean up board identificationBen Hutchings2-55/+20
Remove kluge for development boards with unspecified board type. Remove assumption of contiguous board type code assignments. Signed-off-by: Ben Hutchings <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2008-12-12sfc: Add phy_type device attributeBen Hutchings1-0/+19
Signed-off-by: Ben Hutchings <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2008-12-12sfc: Add support for MMDs numbered >15Ben Hutchings4-22/+24
Combine DEVS0 and DEVS1 registers into a 32-bit mask instead of reading just DEVS0. Signed-off-by: Ben Hutchings <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2008-12-12sfc: Remove MII extension cruftBen Hutchings8-174/+18
Replace efx_nic::link_options bitfield with link_speed (speed in Mbit/s) and link_fd (full duplex flag). Remove broken auto-negotiation functions. Signed-off-by: Ben Hutchings <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2008-12-12sfc: Don't count RX checksum errors during loopback self-testBen Hutchings1-5/+8
The loopback self-test checks that IP packets with incorrect checksums are not altered when sent on a queue with checksum generation off. These should not contribute to RX error statistics. Signed-off-by: Ben Hutchings <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2008-12-12sfc: Abbreviate self-test names so they are not truncatedBen Hutchings1-8/+8
Change "channel" to "chan". Shorten PHY loopback names. Signed-off-by: Ben Hutchings <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2008-12-12sfc: Provide hints to irqbalance daemonBen Hutchings3-1/+27
Allocate IRQs with the name format <device>[-<type>]-<number> so that future versions of irqbalanced understand what we're doing. Signed-off-by: Ben Hutchings <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2008-12-12sfc: Add option to use a separate channel for TX completionsNeil Turton2-15/+28
In a bidirectional forwarding test, we find that the best performance is achieved by sending the TX completion interrupts from one NIC to a CPU which shares an L2 cache with RX completion interrupts from the other NIC. To facilitate this, add an option (through a module parameter) to create separate channels for RX and TX completion with separate IRQs when MSI-X is available. Signed-off-by: Ben Hutchings <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2008-12-12sfc: Restore phy_flash_cfg module parameterBen Hutchings1-0/+7
This is needed for recovery in case a PHY firmware upgrade is aborted. Signed-off-by: Ben Hutchings <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2008-12-12sfc: Work around unreliable strap pinsBen Hutchings1-70/+44
The SFC4000 has strap pins indicating the presence of SPI flash and/or EEPROM. These pins are also used for GPIO, and in some cases they may be read wrongly at reset. However, on production boards it must boot from one or the other device, so we can assume the boot device is present and read the board config from there. Signed-off-by: Ben Hutchings <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2008-12-12sfc: Clean up waits for flash/EEPROM operationsBen Hutchings3-23/+39
Make falcon_spi_wait() ignore the write timer - it is only relevant to write commands, it only works for the device that contains VPD, and it might not be initialised properly at all. Rename falcon_spi_fast_wait() to falcon_spi_wait_write(), reflecting its use, and make it wait up to 10 ms (not 1 ms) since buffered writes to EEPROM may take this long to complete. Make both wait functions sleep instead of busy-waiting. Replace wait for command completion at top of falcon_spi_cmd() with a single poll; no command should be running when the function starts. Correct some comments. Signed-off-by: Ben Hutchings <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2008-12-12sfc: Make reset_workqueue driver-global rather than per-NICSteve Hodgson2-27/+20
Each reset is serialised by the rtnl_lock anyway, so there's no win per-NIC. Signed-off-by: Ben Hutchings <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2008-12-12sfc: Correct interpretation of second param to ethtool phys_id()Ben Hutchings1-2/+6
A value of 0 means indefinite repetition (until interrupted). Signed-off-by: Ben Hutchings <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2008-12-12sfc: Remove unneeded register writeBen Hutchings1-9/+0
This was only ever needed for an FPGA version of Falcon. Signed-off-by: Ben Hutchings <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2008-12-12sfc: Change SPI lengths to type size_tBen Hutchings2-10/+11

2008-12-12sfc: Board support fixesBen Hutchings1-0/+2
Set dummy monitor method for unrecognised boards. Clean up board resources if efx_pci_probe_main() fails after board has been initialised. Signed-off-by: Ben Hutchings <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2008-11-21sfc: convert to net_device_opsStephen Hemminger1-13/+18
Convert driver to new net_device_ops. Compile tested only. Signed-off-by: Stephen Hemminger <[email protected]> Acked-by: Ben Hutchings <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2008-11-20sfc: Fix dependency for SFC_MTDBen Hutchings1-1/+1
Randy Dunlap found that SFC_MTD was selected when sfc was built-in and the MTD core was a module. Don't allow that combination. Signed-off-by: Ben Hutchings <[email protected]> Acked-by: Randy Dunlap <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2008-11-19netdev: introduce dev_get_stats()Stephen Hemminger1-1/+1
In order for the network device ops get_stats call to be immutable, the handling of the default internal network device stats block has to be changed. Add a new helper function which replaces the old use of internal_get_stats. Note: change return code to make it clear that the caller should not go changing the returned statistics. Signed-off-by: Stephen Hemminger <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2008-11-07sfc: Correct address of gPXE boot configuration in EEPROMBen Hutchings1-2/+2
Due to a hardware bug, the originally assigned range cannot reliably be used for boot configuration and must not be modifiable through ethtool. Signed-off-by: Ben Hutchings <[email protected]> Signed-off-by: Jeff Garzik <[email protected]>
2008-11-06sfc: Do not reset when hardware monitor detects a faultBen Hutchings2-23/+6
The TX watchdog should trigger a reset, but a temperature/power alarm should not as this is unlikely to solve the problem. Signed-off-by: Ben Hutchings <[email protected]> Signed-off-by: Jeff Garzik <[email protected]>
2008-11-06sfc: Use lm87 and lm90 drivers for board temperature/power monitoringBen Hutchings8-64/+265
Add board monitoring to periodic work whenever link is down. For SFE4001, report when a fault has caused the PHY to turn off. For SFE4002, switch XFP PHY into low-power state in case of a fault. Signed-off-by: Ben Hutchings <[email protected]> Signed-off-by: Jeff Garzik <[email protected]>
2008-11-06sfc: Expose flash region storing boot code as MTDBen Hutchings9-7/+327
The boot code that appears as a PCI expansion ROM on the SFC4000 is stored in flash. Expose this as a standard MTD device to allow for in-place upgrades. Signed-off-by: Ben Hutchings <[email protected]> Signed-off-by: Jeff Garzik <[email protected]>
2008-11-06sfc: Clean up non-volatile memory partitioningBen Hutchings4-11/+24
Move flash and EEPROM partition boundary constants into spi.h and rename them to be consistent. Add a comment on the partitioning. Signed-off-by: Ben Hutchings <[email protected]> Signed-off-by: Jeff Garzik <[email protected]>

2008-11-03drivers/net: Kill now superfluous ->last_rx stores.David S. Miller1-1/+1
The generic packet receive code takes care of setting netdev->last_rx when necessary, for the sake of the bonding ARP monitor. Drivers need not do it any more. Some cases had to be skipped over because the drivers were making use of the ->last_rx value themselves. Signed-off-by: David S. Miller <[email protected]>
2008-10-27net: convert print_mac to %pMJohannes Berg1-9/+6
This converts pretty much everything to print_mac. There were a few things that had conflicts which I have just dropped for now, no harm done. I've built an allyesconfig with this and looked at the files that weren't built very carefully, but it's a huge patch. Signed-off-by: Johannes Berg <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2008-09-24sfc: Fix type of FALCON_SPI_MAX_LENBen Hutchings1-1/+1
FALCON_SPI_MAX_LEN has type size_t while other SPI lengths have type unsigned int. This results in warnings from min() on 64-bit architectures where they are different. Add a cast to make it match. From: Steve Hodgson <[email protected]> Signed-off-by: Ben Hutchings <[email protected]> Signed-off-by: Jeff Garzik <[email protected]>
2008-09-24sfc: Use CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS where appropriateBen Hutchings2-2/+2
For some buffers we use a starting offset of either NET_IP_ALIGN or 0 depending on whether we believe the architecture supports efficient access to unaligned words. There is now a config macro specifying whether this is the case, so check that rather than checking for specific architectures.

2008-09-24sfc: Disable interrupts after a fatal interrupt occurs until resetBen Hutchings1-1/+2
This should avoid an interrupt storm, which has been observed in the field with one faulty board. Signed-off-by: Ben Hutchings <[email protected]> Signed-off-by: Jeff Garzik <[email protected]>
2008-09-24sfc: Insert read memory barrier after checking MAC statistics flagBen Hutchings1-1/+3
This prevents speculative reading of the statistics before the completion flag. From: Neil Turton <[email protected]> Signed-off-by: Ben Hutchings <[email protected]> Signed-off-by: Jeff Garzik <[email protected]>
2008-09-24sfc: Stop generating bogus events in tenxpress_check_hw()Ben Hutchings1-2/+1
mdio_clause45_links_ok() correctly checks efx_phy_mode_disabled(), so tenxpress_link_ok() doesn't need to. From: Steve Hodgson <[email protected]> Signed-off-by: Ben Hutchings <[email protected]> Signed-off-by: Jeff Garzik <[email protected]>

2008-09-24sfc: Make queue flushes more reliableBen Hutchings4-126/+141
Increase the potential retry count for RX flushes from 5 to 100. Stop polling the RX_DESC_PTR_TBL to infer that a flush might have happened. Instead absolutely rely on the flush events, unless bug 7803 applies (Falcon rev A only). To keep things quick, request flushes for every TX and RX queue up front, and match up the events to requests.

2008-09-24sfc: Serialise tenxpress_special_reset() with statistics fetchesBen Hutchings1-5/+10
On some boards 10Xpress feeds a 156 MHz clock to the Falcon XMAC. MAC statistics DMA can fail while this clock is stopped during a PHY reset. From: Steve Hodgson <[email protected]> Signed-off-by: Ben Hutchings <[email protected]> Signed-off-by: Jeff Garzik <[email protected]>
2008-09-24sfc: Remove workaround for old firmware bugBen Hutchings7-156/+1
