2017-01-18vhost_net: tx batchingJason Wang1-3/+20
This patch tries to utilize tuntap rx batching by peeking the tx virtqueue during transmission, if there's more available buffers in the virtqueue, set MSG_MORE flag for a hint for backend (e.g tuntap) to batch the packets.

2017-01-18vhost: better detection of available buffersJason Wang1-2/+6
This patch tries to do several tweaks on vhost_vq_avail_empty() for a better performance: - check cached avail index first which could avoid userspace memory access. - using unlikely() for the failure of userspace access - check vq->last_avail_idx instead of cached avail index as the last step. This patch is need for batching supports which needs to peek whether or not there's still available buffers in the ring.

2017-01-18net:add one common config ARCH_WANT_RELAX_ORDER to support relax orderingMao Wenan1-1/+1
Relax ordering(RO) is one feature of 82599 NIC, to enable this feature can enhance the performance for some cpu architecure, such as SPARC and so on. Currently it only supports one special cpu architecture(SPARC) in 82599 driver to enable RO feature, this is not very common for other cpu architecture which really needs RO feature. This patch add one common config CONFIG_ARCH_WANT_RELAX_ORDER to set RO feature, and should define CONFIG_ARCH_WANT_RELAX_ORDER in sparc Kconfig firstly.

2017-01-17stmmac: add missing of_node_putJulia Lawall1-0/+1
The function stmmac_dt_phy provides several possibilities for initializing plat->mdio_node, all of which have the effect of increasing the reference count of the assigned value. This field is not updated elsewhere, so the value is live until the end of the lifetime of plat (devm_allocated), just after the end of stmmac_remove_config_dt. Thus, add an of_node_put on plat->mdio_node in stmmac_remove_config_dt. It is possible that the field mdio_node is never initialized, but of_node_put is NULL-safe, so it is also safe to call of_node_put in that case.

2017-01-16net: mvneta: add BQL supportMarcin Wojtas1-3/+19
Tests showed that when whole bandwidth is consumed, the latency for various kind of traffic can reach high values. With saturated link (e.g. with iperf from target to host) simple ping could take significant amount of time. BQL proved to improve this situation when implemented in mvneta driver. Measurements of ping latency for 3 link speeds: Speed | Latency w/o BQL | Latency with BQL 10 | 7-14 ms | 3.5 ms 100 | 2-12 ms | 0.6 ms 1000 | often timeout | up to 2ms Decreasing latency as above result in sligt performance cost - 4kpps (-1.4%) when pushing 64B packets via two bridged interfaces of Armada 38x. For 1500B packets in the same setup, the mpstat tool showed +8% of CPU occupation (default affinity, second CPU idle). Even though this cost seems reasonable to take, considering other improvements.

2017-01-16net/mlx4_core: Fix racy CQ (Completion Queue) freeJack Morgenstein1-18/+20
In function mlx4_cq_completion() and mlx4_cq_event(), the radix_tree_lookup requires a rcu_read_lock. This is mandatory: if another core frees the CQ, it could run the radix_tree_node_rcu_free() call_rcu() callback while its being used by the radix tree lookup function. Additionally, in function mlx4_cq_event(), since we are adding the rcu lock around the radix-tree lookup, we no longer need to take the spinlock. Also, the synchronize_irq() call for the async event eliminates the need for incrementing the cq reference count in mlx4_cq_event(). Other changes: 1. In function mlx4_cq_free(), replace spin_lock_irq with spin_lock: we no longer take this spinlock in the interrupt context. The spinlock here, therefore, simply protects against different threads simultaneously invoking mlx4_cq_free() for different cq's. 2. In function mlx4_cq_free(), we move the radix tree delete to before the synchronize_irq() calls. This guarantees that we will not access this cq during any subsequent interrupts, and therefore can safely free the CQ after the synchronize_irq calls. The rcu_read_lock in the interrupt handlers only needs to protect against corrupting the radix tree; the interrupt handlers may access the cq outside the rcu_read_lock due to the synchronize_irq calls which protect against premature freeing of the cq. 3. In function mlx4_cq_event(), we change the mlx_warn message to mlx4_dbg. 4. We leave the cq reference count mechanism in place, because it is still needed for the cq completion tasklet mechanism.

The problem being gcc cannot tell that if(IS_ERR()) in mlx5e_route_lookup_ipv4() is equivalent to checking if(err) later, so it assumes that 'out_dev' is used after the 'return PTR_ERR(rt)'. The PTR_ERR_OR_ZERO() case by comparison is fairly easy to detect by gcc, so it can't get that wrong, so it no longer warns. Hadar Hen Zion already attempted to fix the warning earlier by adding fake initializations, but that ended up not fully addressing all warnings, so I'm reverting it now that it is no longer needed.

In the last patch da36e13cf65 ("ipvlan: improvise dev_id generation logic in IPvlan") I missed some part of Dave's suggestion and because of that the dev_id creation could fail in a corner case scenario. This would happen when more or less 64k devices have been already created and several have been deleted. If the devices that are still sticking around are the last n bits from the bitmap. So in this scenario even if lower bits are available, the dev_id search is so narrow that it always fails.

2017-01-16sfc: allow PIO more oftenEdward Cree5-3/+30
If an option descriptor has been sent on a queue but not followed by a packet, there will have been no completion event, so the read and write counts won't match and we'll think we can't do PIO. This combines with the fact that we have two TX queues (for en/disable checksum offload), and that both must be empty for PIO to happen. This patch adds a separate "packet_write_count" that tracks the most recent write_count we expect to see a completion event for; this excludes option descriptors but _includes_ PIO descriptors (even though they look like option descriptors). This is then used, rather than write_count, in efx_nic_tx_is_empty(). We only bother to maintain packet_write_count on EF10, since on Siena (a) there are no option descriptors and it always equals write_count, and (b) there's no PIO, so we don't need it anyway.

2017-01-16be2net: fix MAC addr setting on privileged BE3 VFsIvan Vecera1-2/+10
During interface opening MAC address stored in netdev->dev_addr is programmed in the HW with exception of BE3 VFs where the initial MAC is programmed by parent PF. This is OK when MAC address is not changed when an interfaces is down. In this case the requested MAC is stored to netdev->dev_addr and later is stored into HW during opening. But this is not done for all BE3 VFs so the NIC HW does not know anything about this change and all traffic is filtered. This is the case of bonding if fail_over_mac == 0 where the MACs of the slaves are changed while they are down. The be2net behavior is too restrictive because if a BE3 VF has the FILTMGMT privilege then it is able to modify its MAC without any restriction. To solve the described problem the driver should take care about these privileged BE3 VFs so the MAC is programmed during opening. And by contrast unpriviled BE3 VFs should not be allowed to change its MAC in any case.

2017-01-16ravb: do not use zero-length alignment DMA descriptorMasaru Nagai1-0/+13
Due to alignment requirements of the hardware transmissions are split into two DMA descriptors, a small padding descriptor of 0 - 3 bytes in length followed by a descriptor for rest of the packet. In the case of IP packets the first descriptor will never be zero due to the way that the stack aligns buffers for IP packets. However, for non-IP packets it may be zero. In that case it has been reported that timeouts occur, presumably because transmission stops at the first zero-length DMA descriptor and thus the packet is not transmitted.

2017-01-16mmc: core: Restore parts of the polling policy when switch to HS/HS DDRUlf Hansson1-13/+12
Regressions for not being able to detect an eMMC HS DDR mode card has been reported for the sdhci-esdhc-imx driver, but potentially other sdhci variants may suffer from the similar problem. The commit e173f8911f09 ("mmc: core: Update CMD13 polling policy when switch to HS DDR mode"), is causing the problem. It seems that change moved one step to far, regarding changing the host's timing before polling for a busy card. To fix this, let's move back to the behaviour when the host's timing is updated after the polling, but before the switch status is fetched and validated. In cases when polling with CMD13, we keep validating the switch status at each attempt. However, to align with the other card busy detections mechanism, let's fetch and validate the switch status also after the host's timing is updated.

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull EFI fixes from Ingo Molnar: "A number of regression fixes: - Fix a boot hang on machines that have somewhat unusual memory map entries of phys_addr=0x0 num_pages=0, which broke due to a recent commit. This commit got cherry-picked from the v4.11 queue because the bug is affecting real machines. - Fix a boot hang also reported by KASAN, caused by incorrect init ordering introduced by a recent optimization. - Fix a recent robustification fix to allocate_new_fdt_and_exit_boot() that introduced an invalid assumption.

Pull block fixes from Jens Axboe: - the virtio_blk stack DMA corruption fix from Christoph, fixing and issue with VMAP stacks. - O_DIRECT blkbits calculation fix from Chandan. - discard regression fix from Christoph. - queue init error handling fixes for nbd and virtio_blk, from Omar and Jeff. - two small nvme fixes, from Christoph and Guilherme. - rename of blk_queue_zone_size and bdev_zone_size to _sectors instead, to more closely follow what we do in other places in the block layer. This interface is new for this series, so let's get the naming right before releasing a kernel with this feature.
