* | i40e: Add RSS configuration to virtual channelMitch Williams2016-04-06
| | | | | | | | | | | | | | | | | | | | | | | | Add opcodes and structures to support RSS configuration by PF driver on behalf of the VF drivers. This reduces complexity in the VF driver and allows us to support future hardware designs without modifying the VF driver.

* | i40e: Restrict VF poll mode to only single function mode devicesShannon Nelson2016-04-06
| | | | | | | | | | | | | | | | | | | | | | | | The VFs can request their queues to be set up into polling mode, rather than interrupt mode, which works well for supporting things like DPDK, but this should not be available when working in an multi-function support device.

| | | | | | | | | | | | | | | | | | | | | | | | This patch adds hook to support changing a VF from not-trusted to trusted and vice-versa. Fixed the wrappers and function prototype. Changed the dmesg to reflex the current state better. This patch also disables turning on/off trusted VF in MFP mode.

| | | | | | | | | | | | | | | | | | | | | | | | As it turns out, calling into other files from hot path hurts performance a lot. In this case the majority of the time we call "check FCoE" and the packet is *not* FCoE, but this call was taking 5% of our total cycles spent on receive.

This fixes an earlier patch that converted the bitwise operators over to the logical operators and instead replaces the entire thing with just an if statement since it should be more readable what we are trying to do this way.

* | i40e/i40evf: Allow up to 12K bytes of data per Tx descriptor instead of 8KAlexander Duyck2016-04-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | From what I can tell the practical limitation on the size of the Tx data buffer is the fact that the Tx descriptor is limited to 14 bits. As such we cannot use 16K as is typically used on the other Intel drivers. However artificially limiting ourselves to 8K can be expensive as this means that we will consume up to 10 descriptors (1 context, 1 for header, and 9 for payload, non-8K aligned) in a single send. I propose that we can reduce this by increasing the maximum data for a 4K aligned block to 12K. We can reduce the descriptors used for a 32K aligned block by 1 by increasing the size like this. In addition we still have the 4K - 1 of space that is still unused. We can use this as a bit of extra padding when dealing with data that is not aligned to 4K. By aligning the descriptors after the first to 4K we can improve the efficiency of PCIe accesses as we can avoid using byte enables and can fetch full TLP transactions after the first fetch of the buffer. This helps to improve PCIe efficiency. Below is the results of testing before and after with this patch: Recv Send Send Utilization Service Demand Socket Socket Message Elapsed Send Recv Send Recv Size Size Size Time Throughput local remote local remote bytes bytes bytes secs. 10^6bits/s % S % U us/KB us/KB Before: 87380 16384 16384 10.00 33682.24 20.27 -1.00 0.592 -1.00 After: 87380 16384 16384 10.00 34204.08 20.54 -1.00 0.590 -1.00 So the net result of this patch is that we have a small gain in throughput due to a reduction in overhead for putting together the frame.

This is a monster pull request. I held off on the hfi1 driver updates (the hfi1 driver is intimately tied to the qib driver and the new rdmavt software library that was created to help both of them) in my first pull request. The hfi1/qib/rdmavt update is probably 90% of this pull request. The hfi1 driver is being left in staging so that it can be fixed up in regards to the API that Al and yourself didn't like. Intel has agreed to do the work, but in the meantime, this clears out 300+ patches in the backlog queue and brings my tree and their tree closer to sync. This also includes about 10 patches to the core and a few to mlx5 to create an infrastructure for configuring SRIOV ports on IB devices. That series includes one patch to the net core that we sent to netdev@ and Dave Miller with each of the three revisions to the series. We didn't get any response to the patch, so we took that as implicit approval. Finally, this series includes Intel's new iWARP driver for their x722 cards. It's not nearly the beast as the hfi1 driver. It also has a linux-next merge issue, but that has been resolved and it now passes just fine. Summary: - A few minor core fixups needed for the next patch series - The IB SRIOV series. This has bounced around for several versions. Of note is the fact that the first patch in this series effects the net core. It was directed to netdev and DaveM for each iteration of the series (three versions total). Dave did not object, but did not respond either. I've taken this as permission to move forward with the series. - The new Intel X722 iWARP driver - A huge set of updates to the Intel hfi1 driver. Of particular interest here is that we have left the driver in staging since it still has an API that people object to. Intel is working on a fix, but getting these patches in now helps keep me sane as the upstream and Intel's trees were over 300 patches apart" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma: (362 commits) IB/ipoib: Allow mcast packets from other VFs IB/mlx5: Implement callbacks for manipulating VFs net/mlx5_core: Implement modify HCA vport command net/mlx5_core: Add VF param when querying vport counter IB/ipoib: Add ndo operations for configuring VFs IB/core: Add interfaces to control VF attributes IB/core: Support accessing SA in virtualized environment IB/core: Add subnet prefix to port info IB/mlx5: Fix decision on using MAD_IFC net/core: Add support for configuring VF GUIDs IB/{core, ulp} Support above 32 possible device capability flags IB/core: Replace setting the zero values in ib_uverbs_ex_query_device net/mlx5_core: Introduce offload arithmetic hardware capabilities net/mlx5_core: Refactor device capability function net/mlx5_core: Fix caching ATOMIC endian mode capability ib_srpt: fix a WARN_ON() message i40iw: Replace the obsolete crypto hash interface with shash IB/hfi1: Add SDMA cache eviction algorithm IB/hfi1: Switch to using the pin query function IB/hfi1: Specify mm when releasing pages ...
| * i40e: Add support for client interface for IWARP driverAnjali Singhai Jain2016-02-29
| | | | | | | | | | | | | | | | | | | | | | | | This patch adds a Client interface for i40iw driver support. Also expands the Virtchannel to support messages from i40evf driver on behalf of i40iwvf driver. This client API is used by the i40iw and i40iwvf driver to access the core driver resources brokered by the i40e driver.

* | i40e: queue-specific settings for interrupt moderationKan Liang2016-02-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For i40e driver, each vector has its own ITR register. However, there are no concept of queue-specific settings in the driver proper. Only global variable is used to store ITR values. That will cause problems especially when resetting the vector. The specific ITR values could be lost. This patch move rx_itr_setting and tx_itr_setting to i40e_ring to store specific ITR register for each queue. i40e_get_coalesce and i40e_set_coalesce are also modified accordingly to support queue-specific settings. To make it compatible with old ethtool, if user doesn't specify the queue number, i40e_get_coalesce will return queue 0's value. While i40e_set_coalesce will apply value to all queues.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use the new AdminQ functions for safely accessing the Rx control registers that may be affected by heavy small packet traffic. We can't use AdminQ calls in i40e_clear_hw() because the HW is being initialized and the AdminQ is not alive. We recently added an AQ related replacement for reading PFLAN_QALLOC, and this patch puts back the original register read.
