2007-07-10sky2: debug interfaceStephen Hemminger
Add an optional debug interface for displaying state of transmit/receive rings. Creates a file debugfs/sky2/ethX for each device that is up. Signed-off-by: Stephen Hemminger <shemminger@linux-foundation.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2007-07-08sky2: Yukon Extreme (88e8071) support.Stephen Hemminger
Enable support for Yukon EX chipset (88e8071). Most of changes are related to new commands to chip for transmit, and change in status and checksumming. Signed-off-by: Stephen Hemminger <shemminger@linux-foundation.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2007-07-08sky2: GPIO registerStephen Hemminger
The General Purpose I/O register is yet another hardware workaround catchall. Enable workaround that vendor driver does to stay but for bug compatiable. Signed-off-by: Stephen Hemminger <shemminger@linux-foundation.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2007-07-08sky2: rename BMU registerStephen Hemminger
This register is more of a test and control register on Yukon2. So rename it to Q_TEST and give some bit definitions. Signed-off-by: Stephen Hemminger <shemminger@linux-foundation.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2007-07-08sky2: Add PCI device specfic register 4 & 5Stephen Hemminger
Need to setup more PCI control control registers are on Yukon EX. Some of these also exist on Yukon EC-U as well. Signed-off-by: Stephen Hemminger <shemminger@linux-foundation.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2007-05-30sky2: enable IRQ on duplex renegotiationStephen Hemminger
Don't want IRQ on FIFO error because there is nothing useful to do with it. But do want IRQ on duplex change. Signed-off-by: Stephen Hemminger <shemminger@linux-foundation.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2007-05-30sky2: dont set bogus bit in PHY registerStephen Hemminger
This code inherited from the sk98lin driver is incorrect on the Yukon2. The GPHY_CTRL register values are specific to the internal PHY of the chip and the values used were leftovers. Driver was setting bit 13 which is now the INT polarity for the PHY! Signed-off-by: Stephen Hemminger <shemminger@linux-foundation.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2007-04-19sky2: EC-U performance and jumbo supportStephen Hemminger
The Yukon EC Ultra chips have transmit settings for store and forward and PCI buffering. By setting these appropriately, normal performance goes from 750Mbytes/sec to 940Mbytes/sec (non-jumbo). It is also possible to do Jumbo mode, but it means turning off TSO and checksum offload so the performance gets worse. There isn't enough buffering for checksum offload to work. Signed-off-by: Stephen Hemminger <shemminger@linux-foundation.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2007-04-19sky2: handle descriptor errorsStephen Hemminger
There should never be descriptor error unless hardware or driver is buggy. But if an error occurs, print useful information, clear irq, and recover. Signed-off-by: Stephen Hemminger <shemminger@linux-foundation.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2007-02-17sky2: transmit timeoutStephen Hemminger
The transmit timeout code could hang, and it would not clear out problems if the hardware was stuck. Change the code to effectively do a device down/up similar to the suspend/resume code. Signed-off-by: Stephen Hemminger <shemminger@linux-foundation.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2007-02-17sky2: dont flush good pause framesStephen Hemminger
Don't mark pause frames as errors. This problem caused transmitter not to pause and would effectively take out a gigabit switch because the it can't handle overrun. Signed-off-by: Stephen Hemminger <shemminger@linux-foundation.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2007-02-07sky2: Yukon Extreme supportStephen Hemminger
This is basic support for the new Yukon Extreme chip, extracted from the new vendor driver 10.0.4.3. Since this is untested hardware, it has a big fat warning for now. Signed-off-by: Stephen Hemminger <shemminger@linux-foundation.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2007-02-07sky2: add Wake On Lan supportStephen Hemminger
Adds basic magic packet wake on lan support to the sky2 driver. Note: initial WOL value is based on BIOS settings. Signed-off-by: Stephen Hemminger <shemminger@linux-foundation.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2007-02-05sky2: better power state managementStephen Hemminger
Improve power management and error handling by using pci_set_power_state(), instead of driver doing PCI PM register changes in the driver. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2006-12-07[PATCH] sky2: sparse warningsStephen Hemminger
Get rid of sparse warnings in sky2 driver because of mixed enum usage. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2006-12-07[PATCH] sky2: receive queue watermark tweakStephen Hemminger
This patch makes the receive performance on some systems go from 714MB/s to 941MB/s. It adjusts the watermark of the receive queue to be lower, thereby avoiding excess hardware flow control. This is most important on the systems which have little/no additional buffering. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2006-12-02[PATCH] sky2: msi enhancements.Stephen Hemminger
If using Message Signaled Interrupts (MSI) then the IRQ will never be shared. Don't call pci_disable_msi() unless using MSI. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2006-12-02[PATCH] sky2: fixes for Yukon EC_U chip revisionsStephen Hemminger
Update workarounds for 88E803X based on the latest SysKonnect vendor driver version (8.41). Tested on EC_U rev A1, only. These up the receive performance. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2006-10-17sky2: GMAC pause frameStephen Hemminger
This reverts earlier change that attempted to fix flow control. Device needs to discard pause frames, otherwise it hangs after a while. Signed-off-by: Stephen Hemminger <shemminger@osdl.org>
2006-10-17sky2: flow control setting fixesStephen Hemminger
The result of flow control negotiation should not limit the next negotiatition. If board is plugged into an old half duplex 10Mbit port, without pause, then replugged into a gigabit port, it should negotiate what is desired, not inherit that last negotiation. Signed-off-by: Stephen Hemminger <shemminger@osdl.org>
2006-10-17sky2: advertising register 16 bitsStephen Hemminger
The advertising bits (from ethtool.h) fit in 16 bits.
2006-10-11[PATCH] sky2: revert pci express extensionsStephen Hemminger
The pci express error handling extensions don't work unless PCI access is via mmconfig. Otherwise, all accesses to pci config registers greater than 256 fail. Since the sky2 driver has other ways of getting to PCI config space, it works around this short coming, but the pci_find_ext_capablity doesn't work. This backs out commit 91aeb3edbcf4e6ed72d138ac8c22fd68e6d717c3 Go back to hardcoding, since we know where the error registers are anyway.

2006-09-27[PATCH] sky2: fragmented receive for large MTUStephen Hemminger
Use hardware support for chained receive to break up large frames into multiple pages. This avoids having to do a mult-page allocation that can fail on a busy system due to fragmented memory. For normal size MTU, this code behaves the same. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2006-09-27[PATCH] sky2: use netif_tx_lock instead of LLTXStephen Hemminger
Use the netdevice transmit lock via netif_tx_lock rather than putting lock in device specific code and using lockless transmit. The code is cleaner using netif_tx_lock, and the performance is same. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2006-09-27[PATCH] sky2: incremental transmit completionStephen Hemminger
Since a transmit can take several control blocks, the old code waited until the last control block was marked as done. This code processes the return values incrementally. This makes slots in the tx ring available and less chance of getting stuck. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2006-09-27[PATCH] sky2: use standard pci register capabilties for error registerStephen Hemminger
Use the standard pci capability mechanism to access PCI express error registers, rather than hard coding the offset. Mask off the PCI express error from ever occuring on non-PCI express systems. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2006-09-13[PATCH] sky2: big endianStephen Hemminger
Fix support for big endian platforms like PPC. Still not sure about VLAN acceleration (does it need swapping)? Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2006-09-13[PATCH] sky2: fiber supportStephen Hemminger
Fix the support for fiber connected gigabit boards. Allow half duplex gigabit to be configured. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2006-09-13[PATCH] sky2: tx pause bug fixStephen Hemminger
Fix problems with transmit pause frames. The driver was telling the GMAC to flush (not process) pause frames. Manually disabling pause wasn't working because of problems in the setup. This maybe the cause of the lockup under load. http://bugzilla.kernel.org/show_bug.cgi?id=6839 Patch against netdev-2.6 git tree Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2006-08-29[PATCH] sky2: optimize checksum offload informationshemminger@osdl.org
Since many packets have the same checksum starting offset and insertion location; the driver can save the last information and only tell hardware when it changes. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2006-08-29[PATCH] sky2: dont use force status bitshemminger@osdl.org
Don't use force status bit. It was never implemented on all chips, or has no impact. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2006-07-12[PATCH] sky2: fix truncated collision threshold maskStephen Hemminger
Patch to correct broken collision threshold mask in sky2 driver. Should be three bits wide, but the mask only allows for 1 bit to be set. Thanks & Regards Neil Signed-off-by: Neil Horman <nhorman@tuxdriver.com> Signed-off-by: Stephen Hemminger <shemminger@osdl.org> sky2.h | 2 +- 1 files changed, 1 insertion(+), 1 deletion(-) Signed-off-by: Jeff Garzik <jeff@garzik.org>
2006-05-20[PATCH] sky2: more fixes for Yukon UltraStephen Hemminger
Logic error in the phy initialization code. Also, turn on wake on lan bit in status control. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2006-05-08Add more support for the Yukon Ultra chip found in dual core centino laptops.Stephen Hemminger
The newest Yukon Ultra chipset's require more special tweaks. They seem to be like the Yukon XL chipsets. This code is transliterated from the latest SysKonnect driver; I don't have any Ultra hardware. Signed-off-by: Stephe Hemminger <shemminger@osdl.org> Signed-off-by: Stephen Hemminger <shemminger@osdl.org>
2006-04-26[PATCH] sky2: add fake idle irq timerStephen Hemminger
Add an fake NAPI schedule once a second. This is an attempt to work around for broken configurations with edge-triggered interrupts. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2006-04-12[PATCH] sky2: bad memory reference on dual port cardsStephen Hemminger
Sky2 driver will oops referencing bad memory if used on a dual port card. The problem is accessing past end of MIB counter space. Applies for both 2.6.17 and 2.6.16 (with fuzz) Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>

Expose all the available hardware statistics via ethtool. And cleanup some of the statistics definitions. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2006-03-21[PATCH] sky2: handle all error irqsStephen Hemminger
The hardware has additional error trap interrupt bits. I have never seen them trigger, but if they do, it looks like this might be useful. Signed-off-by: Stephen Hemminger <shemminger@osdl.rog> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2006-03-21[PATCH] sky2: add MSI supportStephen Hemminger
Add MSI support to sky2 driver. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2006-03-21[PATCH] sky2: rework of NAPI and IRQ managementStephen Hemminger
Redo the interupt handling of sky2 driver based on the IRQ mangement documentation. All interrupts are handled by the device0 NAPI poll routine. Don't need to adjust interrupt mask in IRQ context, done only when changing device under RTNL. Therefore don't need hwlock anymore. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2006-03-21[PATCH] sky2: drop broken wake on lan supportStephen Hemminger
Remove wake on lan support for now. It doesn't work right, and I don't have a machine with working suspend/resume to test or fix it. It will be re-enabled later. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2006-03-21[PATCH] sky2: remove support for untested Yukon EC/rev 0Stephen Hemminger
The Yukon EC/rev0 (A1) chipset requires a bunch of workarounds. I copied these from sk98lin. But since they never got tested and add more cruft to the code; any attempt at using driver as is on this version will probably fail. It looks like this was a early engineering sample chip revision, if it ever shows up on a real system. Produce an error message. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2006-02-28[PATCH] sky2: remove MSI supportStephen Hemminger
Remove Message Signaled Interrupt support (for 2.6.16). MSI is inherently edge-triggered and that is incompatiable (without more work) with NAPI. In future, will replace with smarter lockless-IRQ handling like tg3.c Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2006-02-23[PATCH] sky2: close race on IRQ mask update.Stephen Hemminger
Need to avoid race in updating IRQ mask. This can probably be replaced smarter use of the interrupt control registers (if/when chipset docs are available). Signed-off-by: Stephen Hemminger <shemminger@osdl.org>
2006-02-23[PATCH] sky2: use device iomem to access PCI configStephen Hemminger
To avoid problems with PCI config access without ACPI (or busted ACPI tables), use the device's window into PCI config space. I know this probably will upset the purists, but I would rather have users than ACPI testers. It also generates less code. Signed-off-by: Stephen Hemminger <shemminger@osdl.org>
2006-02-23[PATCH] sky2: yukon-ec-u chipset initializationStephen Hemminger
Add more complete setup code for Yukon EC_U chipset. Based on matching code in 8.31 code in SysKonnect vendor driver. Signed-off-by: Stephen Hemminger <shemminger@osdl.org>
2006-02-07[PATCH] sky2: support msi interrupt (revised)Stephen Hemminger
This hardware supports Message Signaled interrupts. When setting up, use software interrupt to check for bad hardware. Signed-off-by: Stephen Hemminger <shemminger @osdl.org> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
2006-02-07[PATCH] sky2: pci config space checkingStephen Hemminger
There were bugs in mmconfig access to PCI space, up to and include 2.6.16-rc1. These prevented the sky2 driver from being able to clear PCI express errors. This patch makes the driver check (during probe), for errors in PCI config access and fail. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
2005-12-12[PATCH] sky2: tx/rx ring data structure splitStephen Hemminger
Split Tx and Rx ring into two different data structures. Tx needs the next value (to handle partial status), and Rx always needs the mapaddr (to handle resubmitting same buffer). Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
