2022-01-07i40e: remove variables set but not usedYang Li1-5/+0
The code that uses variables pe_cntx_size and pe_filt_size has been removed, so they should be removed as well.

2022-01-07i40e: Minimize amount of busy-waiting during AQ sendJedrzej Jagielski3-14/+35
The i40e_asq_send_command will now use a non blocking usleep_range if possible (non-atomic context), instead of busy-waiting udelay. The usleep_range function uses hrtimers to provide better performance and removes the negative impact of busy-waiting in time-critical environments. 1. Rename i40e_asq_send_command to i40e_asq_send_command_atomic and add 5th parameter to inform if called from an atomic context. Call inside usleep_range (if non-atomic) or udelay (if atomic). 2. Change i40e_asq_send_command to invoke i40e_asq_send_command_atomic(..., false). 3. Change two functions: - i40e_aq_set_vsi_uc_promisc_on_vlan - i40e_aq_set_vsi_mc_promisc_on_vlan to explicitly use i40e_asq_send_command_atomic(..., true) instead of i40e_asq_send_command, as they use spinlocks and do some work in an atomic context. All other calls to i40e_asq_send_command remain unchanged.

2022-01-04i40e: Fix incorrect netdev's real number of RX/TX queuesJedrzej Jagielski1-7/+25
There was a wrong queues representation in sysfs during driver's reinitialization in case of online cpus number is less than combined queues. It was caused by stopped NetworkManager, which is responsible for calling vsi_open function during driver's initialization. In specific situation (ex. 12 cpus online) there were 16 queues in /sys/class/net/<iface>/queues. In case of modifying queues with value higher, than number of online cpus, then it caused write errors and other errors. Add updating of sysfs's queues representation during driver initialization.

2021-12-28i40e: switch to napi_build_skb()Alexander Lobakin1-1/+1
napi_build_skb() reuses per-cpu NAPI skbuff_head cache in order to save some cycles on freeing/allocating skbuff_heads on every new Rx or completed Tx. i40e driver runs Tx completion polling cycle right before the Rx one and uses napi_consume_skb() to feed the cache with skbuff_heads of completed entries, so it's never empty and always warm at that moment. Switch to the napi_build_skb() to relax mm pressure on heavy Rx.

2021-12-14net_tstamp: add new flag HWTSTAMP_FLAG_BONDED_PHC_INDEXHangbin Liu1-4/+0
Since commit 94dd016ae538 ("bond: pass get_ts_info and SIOC[SG]HWTSTAMP ioctl to active device") the user could get bond active interface's PHC index directly. But when there is a failover, the bond active interface will change, thus the PHC index is also changed. This may break the user's program if they did not update the PHC timely. This patch adds a new hwtstamp_config flag HWTSTAMP_FLAG_BONDED_PHC_INDEX. When the user wants to get the bond active interface's PHC, they need to add this flag and be aware the PHC index may be changed. With the new flag. All flag checks in current drivers are removed. Only the checking in net_hwtstamp_validate() is kept. Suggested-by: Jakub Kicinski <[email protected]> Signed-off-by: Hangbin Liu <[email protected]> Signed-off-by: David S.

2021-12-10i40e: Use irq_update_affinity_hint()Nitesh Narayan Lal1-4/+4
The driver uses irq_set_affinity_hint() for two purposes: - To set the affinity_hint which is consumed by the userspace for distributing the interrupts - To apply an affinity that it provides for the i40e interrupts The latter is done to ensure that all the interrupts are evenly spread across all available CPUs. However, since commit a0c9259dc4e1 ("irq/matrix: Spread interrupts on allocation") the spreading of interrupts is dynamically performed at the time of allocation. Hence, there is no need for the drivers to enforce their own affinity for the spreading of interrupts. Also, irq_set_affinity_hint() applying the provided cpumask as an affinity for the interrupt is an undocumented side effect. To remove this side effect irq_set_affinity_hint() has been marked as deprecated and new interfaces have been introduced. Hence, replace the irq_set_affinity_hint() with the new interface irq_update_affinity_hint() that only sets the pointer for the affinity_hint.

2021-11-17i40e: Fix changing previously set num_queue_pairs for PFsEryk Rybak1-12/+23
Currently, the i40e_vsi_setup_queue_map is basing the count of queues in TCs on a VSI's alloc_queue_pairs member which is not changed throughout any user's action (for example via ethtool's set_channels callback). This implies that vsi->tc_config.tc_info[n].qcount value that is given to the kernel via netdev_set_tc_queue() that notifies about the count of queues per particular traffic class is constant even if user has changed the total count of queues. This in turn caused the kernel warning after setting the queue count to the lower value than the initial one: $ ethtool -l ens801f0 Channel parameters for ens801f0: Pre-set maximums: RX: 0 TX: 0 Other: 1 Combined: 64 Current hardware settings: RX: 0 TX: 0 Other: 1 Combined: 64 $ ethtool -L ens801f0 combined 40 [dmesg] Number of in use tx queues changed invalidating tc mappings. Priority traffic classification disabled! Reason was that vsi->alloc_queue_pairs stayed at 64 value which was used to set the qcount on TC0 (by default only TC0 exists so all of the existing queues are assigned to TC0). we update the offset/qcount via netdev_set_tc_queue() back to the old value but then the netif_set_real_num_tx_queues() is using the vsi->num_queue_pairs as a value which got set to 40. Fix it by using vsi->req_queue_pairs as a queue count that will be distributed across TCs. Do it only for non-zero values, which implies that user actually requested the new count of queues. For VSIs other than main, stay with the vsi->alloc_queue_pairs as we only allow manipulating the queue count on main VSI.

2021-10-14ethernet: constify references to netdev->dev_addr in driversJakub Kicinski1-1/+1
This big patch sprinkles const on local variables and function arguments which may refer to netdev->dev_addr. Commit 406f42fa0d3c ("net-next: When a bond have a massive amount of VLANs...") introduced a rbtree for faster Ethernet address look up. To maintain netdev->dev_addr in this tree we need to make all the writes to it got through appropriate helpers. Some of the changes here are not strictly required - const is sometimes cast off but pointer is not used for writing. It seems like it's still better to add the const in case the code changes later or relevant -W flags get enabled for the build. No functional changes.

When VSI set up failed in i40e_probe() as part of PF switch set up driver was trying to free misc IRQ vectors in i40e_clear_interrupt_scheme and produced a kernel Oops: Trying to free already-free IRQ 266 WARNING: CPU: 0 PID: 5 at kernel/irq/manage.c:1731 __free_irq+0x9a/0x300 Workqueue: events work_for_cpu_fn RIP: 0010:__free_irq+0x9a/0x300 Call Trace: ? synchronize_irq+0x3a/0xa0 free_irq+0x2e/0x60 i40e_clear_interrupt_scheme+0x53/0x190 [i40e] i40e_probe.part.108+0x134b/0x1a40 [i40e] ? kmem_cache_alloc+0x158/0x1c0 ? acpi_ut_update_ref_count.part.1+0x8e/0x345 ? acpi_ut_update_object_reference+0x15e/0x1e2 ? strstr+0x21/0x70 ? irq_get_irq_data+0xa/0x20 ? mp_check_pin_attr+0x13/0xc0 ? irq_get_irq_data+0xa/0x20 ? mp_map_pin_to_irq+0xd3/0x2f0 ? acpi_register_gsi_ioapic+0x93/0x170 ? pci_conf1_read+0xa4/0x100 ? pci_bus_read_config_word+0x49/0x70 ? do_pci_enable_device+0xcc/0x100 local_pci_probe+0x41/0x90 work_for_cpu_fn+0x16/0x20 process_one_work+0x1a7/0x360 worker_thread+0x1cf/0x390 ? create_worker+0x1a0/0x1a0 kthread+0x112/0x130 ? kthread_flush_work_fn+0x10/0x10 ret_from_fork+0x1f/0x40 The problem is that at that point misc IRQ vectors were not allocated yet and we get a call trace that driver is trying to free already free IRQ vectors.

2021-10-06i40e: fix endless loop under rtnlJiri Benc1-1/+1
The loop in i40e_get_capabilities can never end. The problem is that although i40e_aq_discover_capabilities returns with an error if there's a firmware problem, the returned error is not checked. There is a check for pf->hw.aq.asq_last_status but that value is set to I40E_AQ_RC_OK on most firmware problems. When i40e_aq_discover_capabilities encounters a firmware problem, it will encounter the same problem on its next invocation. As the result, the loop becomes endless. We hit this with I40E_ERR_ADMIN_QUEUE_TIMEOUT but looking at the code, it can happen with a range of other firmware errors. I don't know what the correct behavior should be: whether the firmware should be retried a few times, or whether pf->hw.aq.asq_last_status should be always set to the encountered firmware error (but then it would be pointless and can be just replaced by the i40e_aq_discover_capabilities return value). However, the current behavior with an endless loop under the rtnl mutex(!) is unacceptable and Intel has not submitted a fix, although we explained the bug to them 7 months ago. This may not be the best possible fix but it's better than hanging the whole system on a firmware bug.

2021-09-28i40e: Use the xsk batched rx allocation interfaceMagnus Karlsson1-27/+25
Use the new xsk batched rx allocation interface for the zero-copy data path. As the array of struct xdp_buff pointers kept by the driver is really a ring that wraps, the allocation routine is modified to detect a wrap and in that case call the allocation function twice. The allocation function cannot deal with wrapped rings, only arrays. As we now know exactly how many buffers we get and that there is no wrapping, the allocation function can be simplified even more as all if-statements in the allocation loop can be removed, improving performance.

2021-08-19i40e: Fix ATR queue selectionArkadiusz Kubalewski1-2/+1
Without this patch, ATR does not work. Receive/transmit uses queue selection based on SW DCB hashing method. If traffic classes are not configured for PF, then use netdev_pick_tx function for selecting queue for packet transmission. Instead of calling i40e_swdcb_skb_tx_hash, call netdev_pick_tx, which ensures that packet is transmitted/received from CPU that is running the application. Reproduction steps: 1. Load i40e driver 2. Map each MSI interrupt of i40e port for each CPU 3. Disable ntuple, enable ATR i.e.: ethtool -K $interface ntuple off ethtool --set-priv-flags $interface flow-director-atr 4. Run application that is generating traffic and is bound to a single CPU, i.e.: taskset -c 9 netperf -H 1.1.1.1 -t TCP_RR -l 10 5. Observe behavior: Application's traffic should be restricted to the CPU provided in taskset.

2021-07-27dev_ioctl: split out ndo_eth_ioctlArnd Bergmann1-1/+1
Most users of ndo_do_ioctl are ethernet drivers that implement the MII commands SIOCGMIIPHY/SIOCGMIIREG/SIOCSMIIREG, or hardware timestamping with SIOCSHWTSTAMP/SIOCGHWTSTAMP. Separate these from the few drivers that use ndo_do_ioctl to implement SIOCBOND, SIOCBR and SIOCWANDEV commands. This is a purely cosmetic change intended to help readers find their way through the implementation.

In SW DCB mode the packets sent receive incorrect UP tags. They are constructed correctly and put into tx_ring, but UP is later remapped by HW on the basis of TCTUPR register contents according to Tx queue selected, and BW used is consistent with the new UP values. This is caused by Tx queue selection in kernel not taking into account DCB configuration. This patch fixes the issue by implementing the ndo_select_queue NDO callback.

2021-07-19i40e: improve locking of mac_filter_hashStefan Assmann1-3/+20
i40e_config_vf_promiscuous_mode() calls i40e_getnum_vf_vsi_vlan_filters() without acquiring the mac_filter_hash_lock spinlock. This is unsafe because mac_filter_hash may get altered in another thread while i40e_getnum_vf_vsi_vlan_filters() traverses the hashes. Simply adding the spinlock in i40e_getnum_vf_vsi_vlan_filters() is not possible as it already gets called in i40e_get_vlan_list_sync() with the spinlock held. Therefore adding a wrapper that acquires the spinlock and call the correct function where appropriate.
