2015-01-16amd-xgbe: Add ACPI supportLendacky, Thomas1-44/+158
Add support for ACPI to the amd-xgbe and amd-xgbe-phy drivers. This support converts many of the device tree APIs to the new device_property APIs. Signed-off-by: Tom Lendacky <thomas.lendacky@amd.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2015-01-16amd-xgbe: Clear all state during a device restartLendacky, Thomas1-0/+1
When performing a device restart, like during an MTU change, sometimes the device queues still have data and get hung up trying to flush resulting in the device becoming unresponsive until brought down and back up. To prevent this, always perform a device reset during a restart. Signed-off-by: Tom Lendacky <thomas.lendacky@amd.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-11-16amd-xgbe: use netdev_rss_key_fill() helperEric Dumazet1-1/+1
Use netdev_rss_key_fill() helper, as it provides better support for some bonding setups. Signed-off-by: Eric Dumazet <edumazet@google.com> Cc: Lendacky, Thomas <Thomas.Lendacky@amd.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-11-05amd-xgbe: Provide support for receive side scalingLendacky, Thomas1-0/+16
This patch provides support for receive side scaling (RSS). RSS allows for spreading incoming network packets across the Rx queues. When used in conjunction with the per DMA channel interrupt support, this allows the receive processing to be spread across multiple processors.

2014-11-05amd-xgbe: Add support for per DMA channel interruptsLendacky, Thomas1-2/+8
This patch provides support for interrupts that are generated by the Tx/Rx DMA channel pairs of the device. This allows for Tx and Rx processing to run across multiple processsors. Signed-off-by: Tom Lendacky <thomas.lendacky@amd.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-11-05amd-xgbe: Move ring allocation to device openLendacky, Thomas1-62/+0
Move the channel and ring tracking structures allocation to device open. This will allow for future support to vary the number of Tx/Rx queues without unloading the module. Signed-off-by: Tom Lendacky <thomas.lendacky@amd.com> Signed-off-by: David S. Miller <davem@davemloft.net>

This patch contains fixes identified by checkpatch when run with the strict option. Signed-off-by: Tom Lendacky <thomas.lendacky@amd.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-09-02amd-xgbe: Fix initialization of the wrong spin lockLendacky, Thomas1-1/+1
During allocation and initialization of the network driver structures, the wrong pointer is used to initialize a spin lock. Fix the spin lock initialization by using the proper pointer. Signed-off-by: Tom Lendacky <thomas.lendacky@amd.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-08-05amd-xgbe: Use dma_set_mask_and_coherent to set DMA maskLendacky, Thomas1-2/+5
Use the dma_set_mask_and_coherent function to set the DMA mask rather than setting the DMA mask fields directly. This was originally done to work around a bug in the arm64 DMA support when RAM started above the 4GB boundary which has since been fixed.

2014-07-30amd-xgbe: Add traffic class supportLendacky, Thomas1-1/+4
This patch adds support for traffic classes as well as support for Data Center Bridging interfaces related to traffic classes and priority flow control. Signed-off-by: Tom Lendacky <thomas.lendacky@amd.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-07-30amd-xgbe: Base queue fifo size and enablement on ring countLendacky, Thomas1-1/+9
When setting the fifo sizes for the queues and enabling the queues use the number of active Tx and Rx queues that have been enabled not the maximum number available. Signed-off-by: Tom Lendacky <thomas.lendacky@amd.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-07-30amd-xgbe: Add hardware timestamp supportLendacky, Thomas1-4/+17

2014-07-07amd-xgbe: Base AXI DMA cache settings on device treeLendacky, Thomas1-0/+10
The default cache operations for ARM64 were changed during 3.15. To use coherent operations a "dma-coherent" device tree property is required. If that property is not present in the device tree node then the non-coherent operations are assigned for the device. Add support to the amd-xgbe driver to assign the AXI DMA cache settings based on whether the "dma-coherent" property is present in the device node. If present, use settings that work with the caches. If not present, use settings that do not look at the caches. Signed-off-by: Tom Lendacky <thomas.lendacky@amd.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-06-26amd-xgbe: Change destination address filtering supportLendacky, Thomas1-0/+2
Currently the driver makes use of the additional mac address registers in the hardware to provide perfect filtering. The hardware can also have a set of hash table registers that can be used for imperfect filtering. By using imperfect filtering the additional mac address registers can be used for layer 2 filtering support. Use the hash table registers if the device has them.

2014-06-26amd-xgbe: Add support for VLAN filteringLendacky, Thomas1-1/+2
This patch adds support for (imperfect) filtering of VLAN tag ids using a 16-bit filter hash table. When VLANs are added, a 4-bit hash is calculated with the result indicating the bit in the hash table to set. This table is used by the hardware to drop packets with a VLAN id that does not hash to a set bit in the table. Signed-off-by: Tom Lendacky <thomas.lendacky@amd.com> Signed-off-by: David S. Miller <davem@davemloft.net>
