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>
2005-12-12[PATCH] sky2: map length optimizationStephen Hemminger
Don't need to keep track of mapping length in ring structure because we can get the same info from other info. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
2005-12-12[PATCH] sky2: phy processing in workqueue rather than taskletStephen Hemminger
Do phy processing in a work queue rather than a tasklet. This means we can let bottom halves run. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
2005-12-12[PATCH] sky2: device structure alignmentStephen Hemminger
It is a useful optimization to rearrange the structure slightly to align receive and transmit portions. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
2005-12-01[PATCH] sky2: remove pci-express hacksshemminger@osdl.org
Eliminate special case tuning for PCI-Express. This code causes receive hangs and doesn't help performance much anyway. Signed-off-by: Stephen Hemminger <shemmnger@osdl.org> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

Add support for Yukon-EC Ultra chip as implemented in SysKonnect's driver version 8.26. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

Cosmetic cleanup's: mostly spelling fixes etc. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
2005-10-28[PATCH] sky2: remove unused definitionsshemminger@osdl.org
The sky2 driver has a lot of register definitions, that were copied over from the skge driver, for areas that don't exist on the Yukon2. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

Use the hardware to do VLAN. Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
2005-09-21[PATCH] sky2: fix FIFO DMA alignment problemsStephen Hemminger
The Yukon2 chip FIFO has a problem recovering from a pause frame if the receive buffer is not aligned. The workaround is to just leave receive buffer at original alignment, which will make IP header unaligned. Rework receive logic for clarity. Need to ignore receive overrun interrupts (or mac hangs). These fixes make the sky2 driver generally usable. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
2005-09-16[PATCH] sky2: driver update.Stephen Hemminger
Here is revised patch against netdev sky2 branch. It includes whitespace fixes, all the changes from the previous review as well as some optimizations and timing fixes to solve some of the hangs. The stall problem is better but not perfect. It appears that under stress the chip can't keep up with the bus and sends a pause frame, then hangs. This version is for testing, and hopefully other eyes might see the root cause of the problem. I don't want to reinvent the ugly watchdog code in the syskonnect version of sk98lin. If you read it you will see, the original driver writer and the hardware developer obviously didn't understand each other. Dual port support is included, but not tested yet. It did require small change to NAPI since both ports share same IRQ. Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
2005-08-17[PATCH] sky2: new experimental Marvell Yukon2 driverStephen Hemminger
New driver for the Marvell Yukon2 Gigabit Ethernet chipset. This driver is based on the skge driver, but using the logic from the SysKonnect version of the sk98lin driver. It should support all the Yukon2 chipsets that are available in many current Intel and AMD motherboards. The driver does support ethtool, tx and rx checksum, and tcp segmentation offload. But it has only been tested for a short while and is known to stop receiving under heavy load. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
