2023-12-13iavf: enable symmetric-xor RSS for Toeplitz hash functionAhmed Zaki
Allow the user to set the symmetric Toeplitz hash function via: # ethtool -X eth0 hfunc toeplitz symmetric-xor The driver will reject any new RSS configuration if a field other than (IP src/dst and L4 src/dst ports) is requested for hashing. The symmetric RSS will not be supported on PFs not advertising the ADV RSS Offload flag (ADV_RSS_SUPPORT()), for example the E700 series (i40e).

2023-12-13ice: enable symmetric-xor RSS for Toeplitz hash functionJeff Guo
Allow the user to set the symmetric Toeplitz hash function via: # ethtool -X eth0 hfunc toeplitz symmetric-xor All existing RSS configurations will be converted to symmetric unless they have a non-symmetric field (other than IP src/dst and L4 src/dst ports) used for hashing. The driver will reject a new RSS configuration if such a field is requested. The hash function in the E800 NICs is set per-VSI and a specific AQ command is needed to modify the hash function. Use the AQ command to enable setting the symmetric Toeplitz RSS hash function for any VSI in the new ice_set_rss_hfunc(). When the Symmetric Toeplitz hash function is used, the hardware sets the input set of the RSS (Toeplitz) algorithm to be the XOR of the fields index by HSYMM and the fields index by the INSET registers. We use this to create a symmetric hash by setting the HSYMM registers to point to their counterparts in the INSET registers: HSYMM [src_fv] = dst_fv; HSYMM [dst_fv] = src_fv; where src_fv and dst_fv are the indexes of the protocol's src and dst fields.

2023-12-13ice: refactor the FD and RSS flow ID generationAhmed Zaki
The flow director and RSS blocks use separate methods to generate a unique 64 bit ID for the flow. This is not extendable, especially for the RSS that already uses all 64 bit space. Refactor the flow generation API so that the ID is generated within ice_flow_add_prof(). The FD and RSS blocks caches the generated ID for later use.

2023-12-13ice: refactor RSS configurationQi Zhang
Refactor the driver to use a communication data structure for RSS config. To do so we introduce the new ice_rss_hash_cfg struct, and then pass it as an argument to several functions. Also introduce enum ice_rss_cfg_hdr_type to specify a more granular and flexible RSS configuration: ICE_RSS_OUTER_HEADERS - take outer layer as RSS input set ICE_RSS_INNER_HEADERS - take inner layer as RSS input set ICE_RSS_INNER_HEADERS_W_OUTER_IPV4 - take inner layer as RSS input set for packet with outer IPV4 ICE_RSS_INNER_HEADERS_W_OUTER_IPV6 - take inner layer as RSS input set for packet with outer IPV6 ICE_RSS_ANY_HEADERS - try with outer first then inner (same as the behaviour without this change) Finally, move the virtchnl_rss_algorithm enum to be with the other RSS related structures in the virtchnl.h file. There should be no functional change due to this patch.

The get/set_rxfh ethtool ops currently takes the rxfh (RSS) parameters as direct function arguments. This will force us to change the API (and all drivers' functions) every time some new parameters are added. This is part 1/2 of the fix, as suggested in [1]: - First simplify the code by always providing a pointer to all params (indir, key and func); the fact that some of them may be NULL seems like a weird historic thing or a premature optimization. It will simplify the drivers if all pointers are always present. - Then make the functions take a dev pointer, and a pointer to a single struct wrapping all arguments. The set_* should also take an extack.

2023-12-13ice: Support XDP hints in AF_XDP ZC modeLarysa Zaremba
In AF_XDP ZC, xdp_buff is not stored on ring, instead it is provided by xsk_buff_pool. Space for metadata sources right after such buffers was already reserved in commit 94ecc5ca4dbf ("xsk: Add cb area to struct xdp_buff_xsk"). Some things (such as pointer to packet context) do not change on a per-packet basis, so they can be set at the same time as RX queue info. On the other hand, RX descriptor is unique for each packet, but is already known when setting DMA addresses. This minimizes performance impact of hints on regular packet processing. Update AF_XDP ZC packet processing to support XDP hints.

2023-12-13ice: Support RX hash XDP hintLarysa Zaremba
RX hash XDP hint requests both hash value and type. Type is XDP-specific, so we need a separate way to map these values to the hardware ptypes, so create a lookup table. Instead of creating a new long list, reuse contents of ice_decode_rx_desc_ptype[] through preprocessor. Current hash type enum does not contain ICMP packet type, but ice devices support it, so also add a new type into core code.

2023-12-13ice: Introduce ice_xdp_buffLarysa Zaremba
In order to use XDP hints via kfuncs we need to put RX descriptor and miscellaneous data next to xdp_buff. Same as in hints implementations in other drivers, we achieve this through putting xdp_buff into a child structure. Currently, xdp_buff is stored in the ring structure, so replace it with union that includes child structure. This way enough memory is available while existing XDP code remains isolated from hints. Minimum size of the new child structure (ice_xdp_buff) is exactly 64 bytes (single cache line). To place it at the start of a cache line, move 'next' field from CL1 to CL4, as it isn't used often. This still leaves 192 bits available in CL3 for packet context extensions.

2023-12-13ice: fix theoretical out-of-bounds access in ethtool link modesMichal Schmidt
To map phy types reported by the hardware to ethtool link mode bits, ice uses two lookup tables (phy_type_low_lkup, phy_type_high_lkup). The "low" table has 64 elements to cover every possible bit the hardware may report, but the "high" table has only 13. If the hardware reports a higher bit in phy_types_high, the driver would access memory beyond the lookup table's end. Instead of iterating through all 64 bits of phy_types_{low,high}, use the sizes of the respective lookup tables.

2023-12-05ice: periodically kick Tx timestamp interruptJacob Keller
The E822 hardware for Tx timestamping keeps track of how many outstanding timestamps are still in the PHY memory block. It will not generate a new interrupt to the MAC until all of the timestamps in the region have been read. If somehow all the available data is not read, but the driver has exited its interrupt routine already, the PHY will not generate a new interrupt even if new timestamp data is captured. Because no interrupt is generated, the driver never processes the timestamp data. This state results in a permanent failure for all future Tx timestamps. It is not clear how the driver and hardware could enter this state. However, if it does, there is currently no recovery mechanism. Add a recovery mechanism via the periodic PTP work thread which invokes ice_ptp_periodic_work(). Introduce a new check, ice_ptp_maybe_trigger_tx_interrupt() which checks the PHY timestamp ready bitmask. If any bits are set, trigger a software interrupt by writing to PFINT_OICR. Once triggered, the main timestamp processing thread will read through the PHY data and clear the outstanding timestamp data. Once cleared, new data should trigger interrupts as expected. This should allow recovery from such a state rather than leaving the device in a state where we cannot process Tx timestamps. It is possible that this function checks for timestamp data simultaneously with the interrupt, and it might trigger additional unnecessary interrupts. This will cause a small amount of additional processing.

2023-11-29ice: Fix VF Reset paths when interface in a failed over aggregateDave Ertman
There is an error when an interface has the following conditions: - PF is in an aggregate (bond) - PF has VFs created on it - bond is in a state where it is failed-over to the secondary interface - A VF reset is issued on one or more of those VFs The issue is generated by the originating PF trying to rebuild or reconfigure the VF resources. Since the bond is failed over to the secondary interface the queue contexts are in a modified state. To fix this issue, have the originating interface reclaim its resources prior to the tear-down and rebuild or reconfigure. Then after the process is complete, move the resources back to the currently active interface. There are multiple paths that can be used depending on what triggered the event, so create a helper function to move the queues and use paired calls to the helper (back to origin, process, then move back to active interface) under the same lag_mutex lock.

2023-11-23ice: restore timestamp configuration after device resetJacob Keller
The driver calls ice_ptp_cfg_timestamp() during ice_ptp_prepare_for_reset() to disable timestamping while the device is resetting. This operation destroys the user requested configuration. While the driver does call ice_ptp_cfg_timestamp in ice_rebuild() to restore some hardware settings after a reset, it unconditionally passes true or false, resulting in failure to restore previous user space configuration. This results in a device reset forcibly disabling timestamp configuration regardless of current user settings. This was not detected previously due to a quirk of the LinuxPTP ptp4l application. If ptp4l detects a missing timestamp, it enters a fault state and performs recovery logic which includes executing SIOCSHWTSTAMP again, restoring the now accidentally cleared configuration. Not every application does this, and for these applications, timestamps will mysteriously stop after a PF reset, without being restored until an application restart. Fix this by replacing ice_ptp_cfg_timestamp() with two new functions: 1) ice_ptp_disable_timestamp_mode() which unconditionally disables the timestamping logic in ice_ptp_prepare_for_reset() and ice_ptp_release() 2) ice_ptp_restore_timestamp_mode() which calls ice_ptp_restore_tx_interrupt() to restore Tx timestamping configuration, calls ice_set_rx_tstamp() to restore Rx timestamping configuration, and issues an immediate TSYN_TX interrupt to ensure that timestamps which may have occurred during the device reset get processed. Modify the ice_ptp_set_timestamp_mode to directly save the user configuration and then call ice_ptp_restore_timestamp_mode. This way, reset no longer destroys the saved user configuration. This obsoletes the ice_set_tx_tstamp() function which can now be safely removed. With this change, all devices should now restore Tx and Rx timestamping functionality correctly after a PF reset without application intervention.

2023-11-23ice: unify logic for programming PFINT_TSYN_MSKJacob Keller
Commit d938a8cca88a ("ice: Auxbus devices & driver for E822 TS") modified how Tx timestamps are handled for E822 devices. On these devices, only the clock owner handles reading the Tx timestamp data from firmware. To do this, the PFINT_TSYN_MSK register is modified from the default value to one which enables reacting to a Tx timestamp on all PHY ports. The driver currently programs PFINT_TSYN_MSK in different places depending on whether the port is the clock owner or not. For the clock owner, the PFINT_TSYN_MSK value is programmed during ice_ptp_init_owner just before calling ice_ptp_tx_ena_intr to program the PHY ports. For the non-clock owner ports, the PFINT_TSYN_MSK is programmed during ice_ptp_init_port. If a large enough device reset occurs, the PFINT_TSYN_MSK register will be reset to the default value in which only the PHY associated directly with the PF will cause the Tx timestamp interrupt to trigger. The driver lacks logic to reprogram the PFINT_TSYN_MSK register after a device reset. For the E822 device, this results in the PF no longer responding to interrupts for other ports. This results in failure to deliver Tx timestamps to user space applications. Rename ice_ptp_configure_tx_tstamp to ice_ptp_cfg_tx_interrupt, and unify the logic for programming PFINT_TSYN_MSK and PFINT_OICR_ENA into one place. This function will program both registers according to the combination of user configuration and device requirements. This ensures that PFINT_TSYN_MSK is always restored when we configure the Tx timestamp interrupt.

2023-11-23ice: remove ptp_tx ring parameter flagJacob Keller
Before performing a Tx timestamp in ice_stamp(), the driver checks a ptp_tx ring variable to see if timestamping is enabled on that ring. This value is set for all rings whenever userspace configures Tx timestamping. Ostensibly this was done to avoid wasting cycles checking other fields when timestamping has not been enabled. However, for Tx timestamps we already get an individual per-SKB flag indicating whether userspace wants to request a timestamp on that packet. We do not gain much by also having a separate flag to check for whether timestamping was enabled. In fact, the driver currently fails to restore the field after a PF reset. Because of this, if a PF reset occurs, timestamps will be disabled. Since this flag doesn't add value in the hotpath, remove it and always provide a timestamp if the SKB flag has been set. A following change will fix the reset path to properly restore user timestamping configuration completely. This went unnoticed for some time because one of the most common applications using Tx timestamps, ptp4l, will reconfigure the socket as part of its fault recovery logic.

Implement adding representors one by one. Always set switchdev environment when first representor is being added and clear environment when last one is being removed. Basic switchdev configuration remains the same. Code related to creating and configuring representor was changed. Instead of setting whole representors in one function handle only one representor in setup function. The same with removing representors. Stop representors when new one is being added or removed. Stop means, disabling napi, stopping traffic and removing slow path rule. It is needed because ::q_id will change after remapping, so each representor will need new rule. When representor are stopped rebuild control plane VSI with one more or one less queue. One more if new representor is being added, one less if representor is being removed. Bridge port is removed during unregister_netdev() call on PR, so there is no need to call it from driver side. After that do remap new queues to correct vector. At the end start all representors (napi enable, start queues, add slow path rule).
