Jeff Kirsher says: ==================== 40GbE Intel Wired LAN Driver Updates 2017-03-15 This series contains updates to i40e and i40evf only. Aaron fixes an issue on x710 devices where simultaneous read accesses were interfering with each other, so make sure all devices acquire the NVM lock before reads on all devices. Shannon adds Wake On LAN support feature for x722 devices and cleaned up the opcodes so that they are in numerical order. Mitch adds a client interface to the VF driver, in preparation for the upcoming RDMA-capable hardware (and client driver). Cleaned up the client interface in the PF driver, since it was originally over engineered to handle multiple clients on multiple netdevs, but that did not happen and now there will be one client per driver, so apply the "KISS" (Keep It Simple & Stupid) to the i40e client interface. Bumped the number of MAC filters an untrusted VF can create. Jake fixes an issue where a recent refactor of queue pairs accidentally added all remaining vecotrs to the num_lan_msix which can adversely affect performance. Lihong fixes an ethtool issue with x722 devices where "-e" will error out since its EEPROM has a scope limit at offset 0x5B9FFF, so set the EEPROM length to the scope limit. Also fixed an issue where RSS offloading only worked on PF0. Filip cleans up and clarifies code comment so there is no confusion about MAC/VLAN filter initialization routine. Alex adds support for DMA_ATTR_SKIP_CPU_SYNC and DMA_ATTR_WEAK_ORDERING, which improves performance on architectures that implement either one. Harshitha cleans up confusion on flags disabled due to hardware limitation versus featured disabled by the user, so rename auto_disable_flags to hw_disabled_flags to avoid the confusion. v2: Merged patch #1 and #4 in first version to make patch #3 in this series based on feedback from David Miller. ==================== Signed-off-by: David S.

Commit 88ffbf3e switches to using rhashtables for glocks, hashing over the entire struct lm_lockname instead of its individual fields. On some architectures, struct lm_lockname contains a hole of uninitialized memory due to alignment rules, which now leads to incorrect hash values. Get rid of that hole.

Harshitha Ramamurthy authored
A previous commit introduced a field that tracks the features that are disabled due to HW resource limitations as opposed to the featured disabled by the user. This patch changes the name of the field to make it more readable since it might get confusing when looking at code containing both the flags field and the auto_disable_features field together.

Our original filter limit of 8 was based on behavior that we saw from Linux VMs. Now we're running Other Operating Systems under KVM and we see that they commonly use more MAC filters. Since it seems weird to require people to enable trusted VFs just to boot their OS, bump the number of filters allowed by default.

Alexander Duyck authored
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.

Currently ethtool -e will error out with a X722 interface as its EEPROM has a scope limit at offset 0x5B9FFF.

Jacob Keller authored
This is a solution to avoid adding too many queues to num_lan_msix. A recent refactor of queue pairs accidentally added all remaining vectors to the num_lan_msix which can have adverse performance issues, due to enabling more queues than the number of CPU cores. This patch removes the old calculation, and replaces it with a simple algorithm. 1) add queue pairs up to num_online_cpus(), but capped at half of total vectors 2) then add alternative features such as flow directory and similar 3) finally, add the remaining vectors back to queue pairs, but capped such that the total number of queue pairs does not exceed num_online_cpus().

(KISS is Keep It Simple, Stupid. Or is it?) The client interface vastly overengineered for what it needs to do. It was originally designed to support multiple clients on multiple netdevs, possibly even with multiple drivers. None of this happened, and now we know that there will only ever be one client for i40e (i40iw) and one for i40evf (i40iwvf). So, time for some KISS. Since i40e and i40evf are a Dynasty, we'll simplify this one to match the VF interface. First, be a Destroyer and remove all of the lists and locks required to support multiple clients. Keep one static around to keep track of one client, and track the client instances for each netdev in the driver's pf (or adapter) struct. Now it's Almost Human. Since we already know the client type is iWarp, get rid of any checks for this. Same for VSI type - it's always going to be the same type, so it's just a Parasite. While we're at it, fix up some comments. This makes the function headers actually match the functions. These changes reduce code complexity, simplify maintenance, squash some lurking timing bugs, and allow us to Rock and Roll All Nite.

In preparation for upcoming RDMA-capable hardware, add a client interface to the VF driver. This is a slightly-simplified version of the PF client interface, with the names changed to protect the innocent. Due to the nature of the VF<->PF interactions, the client interface sometimes needs to call back into itself to pass messages. Because of this, we can't use the coarse-grained locking like the PF's client interface uses. Instead, we handle all client interactions in a separate thread so the watchdog can still run and process virtual channel messages.

The more significant portions: Patch #1 would cause timeout when qedr utilizes the highest CIDs availble for it [or when future qede adapters would utilize queues in some constellations]. Patch #4 fixes a leak of mapped addresses; When iommu is enabled, offloaded storage protocols might eventually run out of resources and fail to map additional buffers. Patches #6,#7 were missing in the initial iSCSI infrastructure submissions, and would hamper qedi's stability when it reaches out-of-order scenarios. ==================== Signed-off-by: David S.

Ram Amrani authored
Before iterating over the the LL2 Rx ring, the ring's spinlock is taken via spin_lock_irqsave(). The actual processing of the packet [including handling by the protocol driver] is done without said lock, so qed releases the spinlock and re-claims it afterwards. Problem is that the final spin_lock_irqrestore() at the end of the iteration uses the original flags saved from the initial irqsave() instead of the flags from the most recent irqsave(). So it's possible that the interrupt status would be incorrect at the end of the processing.
