2012-09-05ehea: Remove uses of virt_to_abs() and abs_to_virt()Michael Ellerman1-1/+0
abs_to_virt() simply calls __va() and we'd like to get rid of it, so replace all abs_to_virt() uses with __va(). Similarly virt_to_abs() just calls __pa(). Signed-off-by: Michael Ellerman <[email protected]> Signed-off-by: Benjamin Herrenschmidt <[email protected]>
2012-01-30drivers/net: fix up stale paths from driver reorgPaul Gortmaker1-1/+1
The reorganization of the driver layout in drivers/net left behind some stale paths in comments and in Kconfig help text. Bring them up to date. No actual change to any code takes place here.

2011-11-23ehea: Reduce memory usage in buffer poolsAnton Blanchard1-2/+2
Now that we enable multiqueue by default the ehea driver is using quite a lot of memory for its buffer pools. With 4 queues we consume 64MB in the jumbo packet ring, 16MB in the medium packet ring and 16MB in the tiny packet ring. We should only fill the jumbo ring once the MTU is increased but for now halve it's size so it consumes 32MB. Also reduce the tiny packet ring, with 4 queues we had 16k entries which is overkill.

2011-10-17ehea: Allocate large enough skbs to avoid partial cacheline DMA writesAnton Blanchard1-2/+2
The ehea adapter has a mode where it will avoid partial cacheline DMA writes on receive by always padding packets to fall on a cacheline boundary. Unfortunately we currently aren't allocating enough space for a full ethernet MTU packet to be rounded up, so this optimisation doesn't hit. It's unfortunate that the next largest packet size exposed by the hypervisor interface is 2kB, meaning our skb allocation comes out of a 4kB SLAB. However the performance increase due to this optimisation is quite large and my TCP stream numbers increase from 900MB to 1000MB/sec.

2011-10-17ehea: Remove num_tx_qps module optionAnton Blanchard1-3/+0
The num_tx_qps module option allows a user to configure a different number of tx and rx queues. Now the networking stack is multiqueue aware it makes little sense just to enable the tx queues and not the rx queues so remove the option. v3: [cascardo] fixed conflict with get_stats change Signed-off-by: Anton Blanchard <[email protected]> Signed-off-by: Thadeu Lima de Souza Cascardo <[email protected]> Signed-off-by: David S.

2011-10-17ehea: Remove force_irq logic in napi poll routineAnton Blanchard1-1/+0
commit 18604c548545 (ehea: NAPI multi queue TX/RX path for SMP) added driver specific logic for exiting napi mode. I'm not sure what it was trying to solve and it should be up to the network stack to decide when we are done polling so remove it. v3: [cascardo] Fixed extra parentheses.

2011-10-17ehea: Update multiqueue supportAnton Blanchard1-2/+0
The ehea driver had some multiqueue support but was missing the last few years of networking stack improvements: - Use skb_record_rx_queue to record which queue an skb came in on. - Remove the driver specific netif_queue lock and use the networking stack transmit lock instead. - Remove the driver specific transmit queue hashing and use skb_get_queue_mapping instead. - Use netif_tx_{start|stop|wake}_queue where appropriate. We can also remove pr->queue_stopped and just check the queue status directly. - Print all 16 queues in the ethtool stats. We now enable multiqueue by default since it is a clear win on all my testing so far. v3: [cascardo] fixed use_mcs parameter description [cascardo] set ehea_ethtool_stats_keys as const Signed-off-by: Anton Blanchard <[email protected]> Signed-off-by: Thadeu Lima de Souza Cascardo <[email protected]> Signed-off-by: David S.

2011-10-17ehea: Remove NETIF_F_LLTXAnton Blanchard1-1/+0
Remove the deprecated NETIF_F_LLTX feature. Since the network stack now provides the locking we can remove the driver specific pr->xmit_lock.

2011-09-27ehea: Remove sleep at .ndo_get_stats[email protected]1-0/+1
Currently ehea ndo_get_stats can sleep in two places, in a hcall and in a GFP_KERNEL alloc, which is not correct. This patch creates a delayed workqueue that grabs the information each 1 sec from the hardware, and place it into the device structure, so that, .ndo_get_stats quickly returns the device structure statistics block.
