2019-05-30ice: Add switch rules to handle LLDP packetsDave Ertman1-2/+71
Add call to configure dropping egress LLDP packets in ice_vsi_setup and remove the rule in ice_vsi_release. Add calls to add/remove rule to route LLDP packets to default VSI when FW LLDP engine is disabled/enabled and remove rule if applied during ice_vsi_release. In the function ice_add_eth_mac(), there is a line that hard codes the filter info flag to TX. This is incorrect as this flag will be set by the calling function that built the list of filters to add. So remove the hard coded value. This patch also contains a fix to stop treating the DCBx state of "Not Started" as an error state that kicks DCB in SW mode. This will address having non-cabled interfaces automatically go into SW mode with the FW engine running.

2019-05-29ice: Add support for virtchnl_vector_map.[rxq|txq]_mapAnirudh Venkataramanan1-35/+73
Add support for virtchnl_vector_map.[rxq|txq]_map to use bitmap to associate indicated queues with the specified vector. This support is needed since the Windows AVF driver calls VIRTCHNL_OP_CONFIG_IRQ_MAP for each vector and used the bitmap to indicate the associated queues. Updated ice_vc_dis_qs_msg to not subtract one from virtchnl_irq_map_info.num_vectors, and changed the VSI vector index to the vector id. This change supports the Windows AVF driver which maps one vector at a time and sets num_vectors to one. Using vectors_id to index the vector array . Add check for vector_id zero, and return VIRTCHNL_STATUS_ERR_PARAM if vector_id is zero and there are rings associated with that vector. Vector_id zero is for the OICR.

2019-05-29ice: Refactor interrupt trackingBrett Creeley1-127/+52
Currently we have two MSI-x (IRQ) trackers, one for OS requested MSI-x entries (sw_irq_tracker) and one for hardware MSI-x vectors (hw_irq_tracker). Generally the sw_irq_tracker has less entries than the hw_irq_tracker because the hw_irq_tracker has entries equal to the max allowed MSI-x per PF and the sw_irq_tracker is mainly the minimum (non SR-IOV portion of the vectors, kernel granted IRQs). All of the non SR-IOV portions of the driver (i.e. LAN queues, RDMA queues, OICR, etc.) take at least one of each type of tracker resource. SR-IOV only grabs entries from the hw_irq_tracker. There are a few issues with this approach that can be seen when doing any kind of device reconfiguration (i.e. ethtool -L, SR-IOV, etc.). One of them being, any time the driver creates an ice_q_vector and associates it to a LAN queue pair it will grab and use one entry from the hw_irq_tracker and one from the sw_irq_tracker. If the indices on these does not match it will cause a Tx timeout, which will cause a reset and then the indices will match up again and traffic will resume. The mismatched indices come from the trackers not being the same size and/or the search_hint in the two trackers not being equal. Another reason for the refactor is the co-existence of features with SR-IOV. If SR-IOV is enabled and the interrupts are taken from the end of the sw_irq_tracker then other features can no longer use this space because the hardware has now given the remaining interrupts to SR-IOV. This patch reworks how we track MSI-x vectors by removing the hw_irq_tracker completely and instead MSI-x resources needed for SR-IOV are determined all at once instead of per VF. This can be done because when creating VFs we know how many are wanted and how many MSI-x vectors each VF needs. This also allows us to start using MSI-x resources from the end of the PF's allowed MSI-x vectors so we are less likely to use entries needed for other features (i.e. RDMA, L2 Offload, etc). This patch also reworks the ice_res_tracker structure by removing the search_hint and adding a new member - "end". Instead of having a search_hint we will always search from 0. The new member, "end", will be used to manipulate the end of the ice_res_tracker (specifically sw_irq_tracker) during runtime based on MSI-x vectors needed by SR-IOV. In the normal case, the end of ice_res_tracker will be equal to the ice_res_tracker's num_entries. The sriov_base_vector member was added to the PF structure. It is used to represent the starting MSI-x index of all the needed MSI-x vectors for all SR-IOV VFs. Depending on how many MSI-x are needed, SR-IOV may have to take resources from the sw_irq_tracker. This is done by setting the sw_irq_tracker->end equal to the pf->sriov_base_vector. When all SR-IOV VFs are removed then the sw_irq_tracker->end is reset back to sw_irq_tracker->num_entries. The sriov_base_vector, along with the VF's number of MSI-x (pf->num_vf_msix), vf_id, and the base MSI-x index on the PF (pf->hw.func_caps.common_cap.msix_vector_first_id), is used to calculate the first HW absolute MSI-x index for each VF, which is used to write to the VPINT_ALLOC[_PCI] and GLINT_VECT2FUNC registers to program the VFs MSI-x PCI configuration bits. Also, the sriov_base_vector is used along with VF's num_vf_msix, vf_id, and q_vector->v_idx to determine the MSI-x register index (used for writing to GLINT_DYN_CTL) within the PF's space. Interrupt changes removed any references to hw_base_vector, hw_oicr_idx, and hw_irq_tracker. Only sw_base_vector, sw_oicr_idx, and sw_irq_tracker variables remain. Change all of these by removing the "sw_" prefix to help avoid confusion with these variables and their use.

2019-05-23ice: Fix couple of issues in ice_vsi_releaseBrett Creeley1-11/+13
Currently the driver is calling ice_napi_del() and then unregister_netdev(). The call to unregister_netdev() will result in a call to ice_stop() and then ice_vsi_close(). This is where we call napi_disable() for all the MSI-X vectors. This flow is reversed so make the changes to ensure napi_disable() happens prior to napi_del(). Before calling napi_del() and free_netdev() make sure unregister_netdev() was called. This is done by making sure the __ICE_DOWN bit is set in the vsi->state for the interested VSI.

Currently when probing/removing the driver we allocate/deallocate each vsi->q_vectors array in ice_vsi_alloc_arrays() and ice_vsi_free_arrays() respectively. However, we don't do this during the reset and VSI rebuild flow. This is inconsistent and unnecessary to have a difference between the two flows. This patch makes the change to always allocate/deallocate the vsi->q_vectors array regardless of the driver flow we are in. Also, update the comment for ice_vsi_free_arrays() to be more descriptive.

2019-04-18ice: Add code for DCB initialization part 3/4Anirudh Venkataramanan1-0/+135
This patch adds a new function ice_pf_dcb_cfg (and related helpers) which applies the DCB configuration obtained from the firmware. As part of this, VSIs/netdevs are updated with traffic class information. This patch requires a bit of a refactor of existing code. 1. For a MIB change event, the associated VSI is closed and brought up again. The gap between closing and opening the VSI can cause a race condition. Fix this by grabbing the rtnl_lock prior to closing the VSI and then only free it after re-opening the VSI during a MIB change event. 2. ice_sched_query_elem is used in ice_sched.c and with this patch, in ice_dcb.c as well. However, ice_dcb.c is not built when CONFIG_DCB is unset. This results in namespace warnings (ice_sched.o: Externally defined symbols with no external references) when CONFIG_DCB is unset. To avoid this move ice_sched_query_elem from ice_sched.c to ice_common.c.

Currently the ice_q_vector structure and ice_ring_container structure are taking up more space than necessary due to cache alignment holes and unnecessary variables respectively.

2019-03-22ice: Fix issue reclaiming resources back to the pool after resetAkeem G Abodunrin1-3/+23
This patch fixes issue reclaiming VF resources back to the pool after reset - Since we only allocate HW vector for all VFs and track together with resources allocation for PF with ice_search_res, we need to free VFs resources separately, using first VF vector index to traverse the list. Otherwise tracker starts from the last assigned vectors list and causes maximum supported number of HW vectors, 1024 to be exhausted, depending on the number of VFs enabled, which causes a lot of unwanted issues, and failed to reassign vectors for VFs.

2019-03-19ice: Determine descriptor count and ring size based on PAGE_SIZEBrett Creeley1-4/+24
Currently we set the default number of Tx and Rx descriptors to 128 by default. For Rx this amounts to a full page (assuming 4K pages) because each Rx descriptor is 32 Bytes, but for Tx it only amounts to a half page because each Tx descriptor is 16 Bytes (assuming 4K pages). Instead of assuming 4K pages, determine the ring size and the number of descriptors for Tx and Rx based on a calculation using the PAGE_SIZE, ICE_MAX_NUM_DESC, and ICE_REQ_DESC_MULTIPLE. This change is being made to improve the performance of the driver when using the default settings.

2019-03-19ice: configure GLINT_ITR to always have an ITR gran of 2Brett Creeley1-0/+33
Instead of hoping that our ITR granularity will be 2 usec program the GLINT_CTL register to make sure the ITR granularity is always 2 usecs. Now that we know what the ITR granularity will be get rid of the check in ice_probe() to verify our previous assumption.

2019-03-19ice: remove redundant variable and if conditionBrett Creeley1-7/+4
In ice_pf_rxq_wait we are using an unnecessary local variable and also we are checking if the timeout time was reached after the loop. Get rid of the local variable and return 0 right when we get a successful result. This makes it so we can return -ETIMEDOUT if we ever exit the loop because we know the timeout time has been hit.

2019-02-25ice: sizeof(<type>) should be avoidedBruce Allan1-5/+5
With sizeof(), it is preferable to use the variable of type <type> instead of sizeof(<type>). There are multiple places where a temporary variable is used to hold a 'size' value which is then used for a subsequent alloc/memset. Get rid of the temporary variable by calculating size as part of the alloc/memset statement. Also remove unnecessary type-cast.

2019-01-15ice: Add support for adaptive interrupt moderationBrett Creeley1-6/+18
Currently the driver does not support adaptive/dynamic interrupt moderation. This patch adds support for this. Also, adaptive/dynamic interrupt moderation is turned on by default upon driver load. In order to support adaptive interrupt moderation, two functions were added, ice_update_itr() and ice_itr_divisor(). These are used to determine the current packet load and to determine a divisor based on link speed respectively. This patch also adds the ICE_ITR_GRAN_S define that is used in the hot-path when setting a new ITR value. The shift is used to pet two birds with one hand, set the ITR value while re-enabling the interrupt. Also, the ICE_ITR_GRAN_S is defined as 1 because the device has a ITR granularity of 2usecs.
