* sky2: EC-U performance and jumbo supportStephen Hemminger2007-04-19
| | | | | | | | | | | | | 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.

* sky2: handle descriptor errorsStephen Hemminger2007-04-19
| | | | | | | | 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>
* sky2: transmit timeoutStephen Hemminger2007-02-17
| | | | | | | | | 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>
* sky2: dont flush good pause framesStephen Hemminger2007-02-17
| | | | | | | | | 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>
* sky2: Yukon Extreme supportStephen Hemminger2007-02-07
| | | | | | | | | | 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>
* sky2: add Wake On Lan supportStephen Hemminger2007-02-07
| | | | | | | | 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>
* sky2: better power state managementStephen Hemminger2007-02-05
| | | | | | | | 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>
* [PATCH] sky2: sparse warningsStephen Hemminger2006-12-07

* [PATCH] sky2: receive queue watermark tweakStephen Hemminger2006-12-07
| | | | | | | | | | 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.

* [PATCH] sky2: msi enhancements.Stephen Hemminger2006-12-02
| | | | | | | | 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>
* [PATCH] sky2: fixes for Yukon EC_U chip revisionsStephen Hemminger2006-12-02

* sky2: GMAC pause frameStephen Hemminger2006-10-17
| | | | | | | 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>
* sky2: flow control setting fixesStephen Hemminger2006-10-17
| | | | | | | | | 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.

* sky2: advertising register 16 bitsStephen Hemminger2006-10-17
| | | | The advertising bits (from ethtool.h) fit in 16 bits.
* [PATCH] sky2: revert pci express extensionsStephen Hemminger2006-10-11
| | | | | | | | | | | | | | 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.

* [PATCH] sky2: fragmented receive for large MTUStephen Hemminger2006-09-27
| | | | | | | | | | | 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.

* [PATCH] sky2: use netif_tx_lock instead of LLTXStephen Hemminger2006-09-27
| | | | | | | | | 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>
* [PATCH] sky2: incremental transmit completionStephen Hemminger2006-09-27
| | | | | | | | | | 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>
* [PATCH] sky2: use standard pci register capabilties for error registerStephen Hemminger2006-09-27

* [PATCH] sky2: tx pause bug fixStephen Hemminger2006-09-13
| | | | | | | | | | | | | | 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>
* [PATCH] sky2: optimize checksum offload informationshemminger@osdl.org2006-08-29

| | | | | | | | | | | | 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.

* [PATCH] sky2: remove support for untested Yukon EC/rev 0Stephen Hemminger2006-03-21
| | | | | | | | | | | | 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.

* [PATCH] sky2: remove MSI supportStephen Hemminger2006-02-28
| | | | | | | | | | | | Remove Message Signaled Interrupt support (for 2.6.16). MSI is inherently edge-triggered and that is incompatiable (without more work) with NAPI.

| | | | | | | | | | To avoid problems with PCI config access without ACPI (or busted ACPI tables), use the device's window into PCI config space.
