2017-02-17ptp: create "pins" together with the rest of attributesDmitry Torokhov3-42/+24
Let's switch to using device_create_with_groups(), which will allow us to create "pins" attribute group together with the rest of ptp device attributes, and before userspace gets notified about ptp device creation.

2017-02-17ptp: use is_visible method to hide unused attributesDmitry Torokhov1-70/+55
Instead of creating selected attributes after the device is created (and after userspace potentially seen uevent), lets use attribute group is_visible() method to control which attributes are shown. This will allow us to create all attributes (except "pins" group, which will be taken care of later) before userspace gets notified about new ptp class device.

2017-02-17mlx4: do not fire tasklet unless necessaryEric Dumazet2-9/+6
All rx and rx netdev interrupts are handled by respectively by mlx4_en_rx_irq() and mlx4_en_tx_irq() which simply schedule a NAPI. But mlx4_eq_int() also fires a tasklet to service all items that were queued via mlx4_add_cq_to_tasklet(), but this handler was not called unless user cqe was handled. This is very confusing, as "mpstat -I SCPU ..." show huge number of tasklet invocations. This patch saves this overhead, by carefully firing the tasklet directly from mlx4_add_cq_to_tasklet(), removing four atomic operations per IRQ.

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue Jeff Kirsher says: ==================== 10GbE Intel Wired LAN Driver Updates 2017-02-16 This series contains updates to ixgbe only. Tony updates the driver to advertise 2.5Gb and 5.0Gb if the adapter supports it. Stephen Hemminger renames our dcbnl_ops since it is global to ixgbe_dcbnl_ops to avoid namespace issues. Mark updates the driver version based on the recent changes. Alex has the remainder of the changes, starting with consolidating functions that represent logical steps in the receive process so we can later update them more easily (and align with igb). Modify the receive path to only synchronize the length of the frame versus the entire buffer. Provided performance improvements by adding support for DMA_ATTR_SKIP_CPU_SYNC and DMA_ATTR_WEAK_ORDERING. Also made additional performance gains by batching the page count updates instead of doing them one at a time. Adjusted the receive path to use 3k buffers with 8k backing them in order to support build_skb with jumbo frames. Made additional driver improvements by using the length of the packet instead of the DD status to determine if a new descriptor is ready to be processed, which cuts down on reads. To reduce code duplication, pulled apart the receive path into separate functions. Added support for providing a buffer with headroom and tailroom to allow for shared info for NET_SKB_PAD and NET_IP_ALIGN. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2017-02-16ixgbe: Don't bother clearing buffer memory for descriptor ringsAlexander Duyck2-71/+99
This patch makes it so that we don't need to bother with clearing the memory out for the descriptor rings. The general idea is to only free buffers associated with buffers in use which are located between the next_to_clean and next_to_use or next_to_alloc values. Everything outside of those regions can be safely ignored since they should have no buffers associated with them. The advantage to doing things this way is that is should speed up bring-up and tear-down of the rings. Specifically we can avoid the 512 or more cycles required to memset the rings in tear-down. In the bring-up phase we then clear the memory as a part of initialization. The general idea is that the clearing in initialization can act as a prefetch of sorts for the buffer info structures so they are in the local CPU when we go to populate them. This should help to improve overall time needed to perform a suspend/resume.

2017-02-16ixgbe: Add support for build_skbAlexander Duyck1-1/+48
This patch adds build_skb support to the Rx path. There are several advantages to this change. 1. It avoids the memcpy and skb->head allocation for small packets which improves performance by about 5% in my tests. 2. It avoids the memcpy, skb->head allocation, and eth_get_headlen for larger packets improving performance by about 10% in my tests. 3. For VXLAN packets it allows the full header to be in skb->data which improves the performance by as much as 30% in some of my tests.

2017-02-16ixgbe: Add private flag to control buffer modeAlexander Duyck1-0/+47
Since there are potential drawbacks to the new Rx allocation approach I thought it best to add a "chicken bit" so that we can turn the feature off if in the event that a problem is found. It also provides a means of validating the legacy Rx path in the event that we are forced to fall back. At some point in the future when we are convinced we don't need it anymore we might be able to drop the legacy-rx flag.

2017-02-16ixgbe: Use length to determine if descriptor is doneAlexander Duyck2-7/+9
This change makes it so that we use the length of the packet instead of the DD status bit to determine if a new descriptor is ready to be processed. The obvious advantage is that it cuts down on reads as we don't really even need the DD bit if going from a 0 to a non-zero value on size is enough to inform us that the packet has been completed.

2017-02-16ixgbe: Make use of order 1 pages and 3K buffers independent of FCoEAlexander Duyck2-17/+22
In order to support build_skb with jumbo frames it will be necessary to use 3K buffers for the Rx path with 8K pages backing them. This is needed on architectures that implement 4K pages because we can't support 2K buffers plus padding in a 4K page. In the case of systems that support page sizes larger than 4K the 3K attribute will only be applied to FCoE as we can fall back to using just 2K buffers and adding the padding.

Batch the page count updates instead of doing them one at a time. By doing this we can improve the overall performance as the atomic increment operations can be expensive due to the fact that on x86 they are locked operations which can cause stalls.

This patch adds support for DMA_ATTR_SKIP_CPU_SYNC and DMA_ATTR_WEAK_ORDERING. By enabling both of these for the Rx path we are able to see performance improvements on architectures that implement either one due to the fact that page mapping and unmapping only has to sync what is actually being used instead of the entire buffer. In addition by enabling the weak ordering attribute enables a performance improvement for architectures that can associate a memory ordering with a DMA buffer such as Sparc.

Yuval Mintz says: ==================== qed*: Add support for PTP This patch series adds required changes for qed/qede drivers for supporting the IEEE Precision Time Protocol (PTP). Changes from previous versions: v7: Fixed Kbuild robot warnings. v6: Corrected broken loop iteration in previous version. Reduced approximation error of adjfreq. v5: Removed two divisions from the adjust-frequency loop. Resulting logic would use 8 divisions [instead of 24]. v4: Remove the loop iteration for value '0' in the qed_ptp_hw_adjfreq() implementation. v3: Use div_s64 for 64-bit divisions as do_div gives error for signed types. Incorporated review comments from Richard Cochran. - Clear timestamp resgisters as soon as timestamp is read. - Use shift operation in the place of 'divide by 16'. v2: Use do_div for 64-bit divisions. ==================== Acked-by: Richard Cochran <richardcochran@gmail.com> Signed-off-by: David S.
