2025-03-05ice: register devlink prior to creating health reportersPrzemek Kitszel
ice_health_init() was introduced in the commit 2a82874a3b7b ("ice: add Tx hang devlink health reporter"). The call to it should have been put after ice_devlink_register(). It went unnoticed until next reporter by Konrad, which receives events from FW. FW is reporting all events, also from prior driver load, and thus it is not unlikely to have something at the very beginning.

2025-03-05ice: Fix switchdev slow-path in LAGMarcin Szycik
Ever since removing switchdev control VSI and using PF for port representor Tx/Rx, switchdev slow-path has been working improperly after failover in SR-IOV LAG. LAG assumes that the first uplink to be added to the aggregate will own VFs and have switchdev configured. After failing-over to the other uplink, representors are still configured to Tx through the uplink they are set up on, which fails because that uplink is now down. On failover, update all PRs on primary uplink to use the currently active uplink for Tx. Call netif_keep_dst(), as the secondary uplink might not be in switchdev mode. Also make sure to call ice_eswitch_set_target_vsi() if uplink is in LAG. On the Rx path, representors are already working properly, because default Tx from VFs is set to PF owning the eswitch. After failover the same PF is receiving traffic from VFs, even though link is down.

2025-03-05ice: fix memory leak in aRFS after resetGrzegorz Nitka
Fix aRFS (accelerated Receive Flow Steering) structures memory leak by adding a checker to verify if aRFS memory is already allocated while configuring VSI. aRFS objects are allocated in two cases: - as part of VSI initialization (at probe), and - as part of reset handling However, VSI reconfiguration executed during reset involves memory allocation one more time, without prior releasing already allocated resources. This led to the memory leak with the following signature: [root@os-delivery ~]# cat /sys/kernel/debug/kmemleak unreferenced object 0xff3c1ca7252e6000 (size 8192): comm "kworker/0:0", pid 8, jiffies 4296833052 hex dump (first 32 bytes): 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ backtrace (crc 0): [<ffffffff991ec485>] __kmalloc_cache_noprof+0x275/0x340 [<ffffffffc0a6e06a>] ice_init_arfs+0x3a/0xe0 [ice] [<ffffffffc09f1027>] ice_vsi_cfg_def+0x607/0x850 [ice] [<ffffffffc09f244b>] ice_vsi_setup+0x5b/0x130 [ice] [<ffffffffc09c2131>] ice_init+0x1c1/0x460 [ice] [<ffffffffc09c64af>] ice_probe+0x2af/0x520 [ice] [<ffffffff994fbcd3>] local_pci_probe+0x43/0xa0 [<ffffffff98f07103>] work_for_cpu_fn+0x13/0x20 [<ffffffff98f0b6d9>] process_one_work+0x179/0x390 [<ffffffff98f0c1e9>] worker_thread+0x239/0x340 [<ffffffff98f14abc>] kthread+0xcc/0x100 [<ffffffff98e45a6d>] ret_from_fork+0x2d/0x50 [<ffffffff98e083ba>] ret_from_fork_asm+0x1a/0x30 ...

2025-03-05ice: do not configure destination override for switchdevLarysa Zaremba
After switchdev is enabled and disabled later, LLDP packets sending stops, despite working perfectly fine before and during switchdev state. To reproduce (creating/destroying VF is what triggers the reconfiguration): devlink dev eswitch set pci/<address> mode switchdev echo '2' > /sys/class/net/<ifname>/device/sriov_numvfs echo '0' > /sys/class/net/<ifname>/device/sriov_numvfs This happens because LLDP relies on the destination override functionality. It needs to 1) set a flag in the descriptor, 2) set the VSI permission to make it valid. The permissions are set when the PF VSI is first configured, but switchdev then enables it for the uplink VSI (which is always the PF) once more when configured and disables when deconfigured, which leads to software-generated LLDP packets being blocked. Do not modify the destination override permissions when configuring switchdev, as the enabled state is the default configuration that is never modified.

2025-02-25ice: Avoid setting default Rx VSI twice in switchdev setupMarcin Szycik
As part of switchdev environment setup, uplink VSI is configured as default for both Tx and Rx. Default Rx VSI is also used by promiscuous mode. If promisc mode is enabled and an attempt to enter switchdev mode is made, the setup will fail because Rx VSI is already configured as default (rule exists). Reproducer: devlink dev eswitch set $PF1_PCI mode switchdev ip l s $PF1 up ip l s $PF1 promisc on echo 1 > /sys/class/net/$PF1/device/sriov_numvfs In switchdev setup, use ice_set_dflt_vsi() instead of plain ice_cfg_dflt_vsi(), which avoids repeating setting default VSI for Rx if it's already configured.

2025-01-31ice: stop storing XDP verdict within ice_rx_bufMaciej Fijalkowski
Idea behind having ice_rx_buf::act was to simplify and speed up the Rx data path by walking through buffers that were representing cleaned HW Rx descriptors. Since it caused us a major headache recently and we rolled back to old approach that 'puts' Rx buffers right after running XDP prog/creating skb, this is useless now and should be removed. Get rid of ice_rx_buf::act and related logic. We still need to take care of a corner case where XDP program releases a particular fragment. Make ice_run_xdp() to return its result and use it within ice_put_rx_mbuf().

2025-01-31ice: gather page_count()'s of each frag right before XDP prog callMaciej Fijalkowski
If we store the pgcnt on few fragments while being in the middle of gathering the whole frame and we stumbled upon DD bit not being set, we terminate the NAPI Rx processing loop and come back later on. Then on next NAPI execution we work on previously stored pgcnt. Imagine that second half of page was used actively by networking stack and by the time we came back, stack is not busy with this page anymore and decremented the refcnt. The page reuse algorithm in this case should be good to reuse the page but given the old refcnt it will not do so and attempt to release the page via page_frag_cache_drain() with pagecnt_bias used as an arg. This in turn will result in negative refcnt on struct page, which was initially observed by Xu Du. Therefore, move the page count storage from ice_get_rx_buf() to a place where we are sure that whole frame has been collected, but before calling XDP program as it internally can also change the page count of fragments belonging to xdp_buff.

Introduce a new helper ice_put_rx_mbuf() that will go through gathered frags from current frame and will call ice_put_rx_buf() on them. Current logic that was supposed to simplify and optimize the driver where we go through a batch of all buffers processed in current NAPI instance turned out to be broken for jumbo frames and very heavy load that was coming from both multi-thread iperf and nginx/wrk pair between server and client. The delay introduced by approach that we are dropping is simply too big and we need to take the decision regarding page recycling/releasing as quick as we can. While at it, address an error path of ice_add_xdp_frag() - we were missing buffer putting from day 1 there. As a nice side effect we get rid of annoying and repetitive three-liner: xdp->data = NULL; rx_ring->first_desc = ntc; rx_ring->nr_frags = 0; by embedding it within introduced routine.

Fix &ice_parser_rt::bst_key size. It was wrongly set to 10 instead of 20 in the initial impl commit (see Fixes tag). All usage code assumed it was of size 20. That was also the initial size present up to v2 of the intro series [2], but halved by v3 [3] refactor described as "Replace magic hardcoded values with macros." The introducing series was so big that some ugliness was unnoticed, same for bugs :/ ICE_BST_KEY_TCAM_SIZE and ICE_BST_TCAM_KEY_SIZE were differing by one. There was tmp variable @j in the scope of edited function, but was not used in all places. This ugliness is now gone. I'm moving ice_parser_rt::pg_prio a few positions up, to fill up one of the holes in order to compensate for the added 10 bytes to the ::bst_key, resulting in the same size of the whole as prior to the fix, and minimal changes in the offsets of the fields. Extend also the debug dump print of the key to cover all bytes. To not have string with 20 "%02x" and 20 params, switch to ice_debug_array_w_prefix(). This fix obsoletes Ahmed's attempt at [1].

Core: - More core refactoring to reduce the RTNL lock contention, including preparatory work for the per-network namespace RTNL lock, replacing RTNL lock with a per device-one to protect NAPI-related net device data and moving synchronize_net() calls outside such lock. - Extend drop reasons usage, adding net scheduler, AF_UNIX, bridge and more specific TCP coverage. - Reduce network namespace tear-down time by removing per-subsystems synchronize_net() in tipc and sched. - Add flow label selector support for fib rules, allowing traffic redirection based on such header field. Netfilter: - Do not remove netdev basechain when last device is gone, allowing netdev basechains without devices. - Revisit the flowtable teardown strategy, dealing better with fin, reset and re-open events. - Scale-up IP-vs connection dumping by avoiding linear search on each restart. Protocols: - A significant XDP socket refactor, consolidating and optimizing several helpers into the core - Better scaling of ICMP rate-limiting, by removing false-sharing in inet peers handling. - Introduces netlink notifications for multicast IPv4 and IPv6 address changes. - Add ipsec support for IP-TFS/AggFrag encapsulation, allowing aggregation and fragmentation of the inner IP. - Add sysctl to configure TIME-WAIT reuse delay for TCP sockets, to avoid local port exhaustion issues when the average connection lifetime is very short. - Support updating keys (re-keying) for connections using kernel TLS (for TLS 1.3 only). - Support ipv4-mapped ipv6 address clients in smc-r v2. - Add support for jumbo data packet transmission in RxRPC sockets, gluing multiple data packets in a single UDP packet. - Support RxRPC RACK-TLP to manage packet loss and retransmission in conjunction with the congestion control algorithm.

git://git.kernel.org/pub/scm/linux/kernel/git/frederic/linux-dynticks Pull kthread updates from Frederic Weisbecker: "Kthreads affinity follow either of 4 existing different patterns: 1) Per-CPU kthreads must stay affine to a single CPU and never execute relevant code on any other CPU. This is currently handled by smpboot code which takes care of CPU-hotplug operations. Affinity here is a correctness constraint. 2) Some kthreads _have_ to be affine to a specific set of CPUs and can't run anywhere else. The affinity is set through kthread_bind_mask() and the subsystem takes care by itself to handle CPU-hotplug operations. Affinity here is assumed to be a correctness constraint. 3) Per-node kthreads _prefer_ to be affine to a specific NUMA node. This is not a correctness constraint but merely a preference in terms of memory locality. kswapd and kcompactd both fall into this category. The affinity is set manually like for any other task and CPU-hotplug is supposed to be handled by the relevant subsystem so that the task is properly reaffined whenever a given CPU from the node comes up. Also care should be taken so that the node affinity doesn't cross isolated (nohz_full) cpumask boundaries. 4) Similar to the previous point except kthreads have a _preferred_ affinity different than a node. Both RCU boost kthreads and RCU exp kworkers fall into this category as they refer to "RCU nodes" from a distinctly distributed tree. Currently the preferred affinity patterns (3 and 4) have at least 4 identified users, with more or less success when it comes to handle CPU-hotplug operations and CPU isolation. Each of which do it in its own ad-hoc way. This is an infrastructure proposal to handle this with the following API changes: - kthread_create_on_node() automatically affines the created kthread to its target node unless it has been set as per-cpu or bound with kthread_bind[_mask]() before the first wake-up. - kthread_affine_preferred() is a new function that can be called right after kthread_create_on_node() to specify a preferred affinity different than the specified node. When the preferred affinity can't be applied because the possible targets are offline or isolated (nohz_full), the kthread is affine to the housekeeping CPUs (which means to all online CPUs most of the time or only the non-nohz_full CPUs when nohz_full= is set). kswapd, kcompactd, RCU boost kthreads and RCU exp kworkers have been converted, along with a few old drivers. Summary of the changes: - Consolidate a bunch of ad-hoc implementations of kthread_run_on_cpu() - Introduce task_cpu_fallback_mask() that defines the default last resort affinity of a task to become nohz_full aware - Add some correctness check to ensure kthread_bind() is always called before the first kthread wake up. - Default affine kthread to its preferred node. - Convert kswapd / kcompactd and remove their halfway working ad-hoc affinity implementation - Implement kthreads preferred affinity - Unify kthread worker and kthread API's style - Convert RCU kthreads to the new API and remove the ad-hoc affinity implementation" * tag 'kthread-for-6.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/frederic/linux-dynticks: kthread: modify kernel-doc function name to match code rcu: Use kthread preferred affinity for RCU exp kworkers treewide: Introduce kthread_run_worker[_on_cpu]() kthread: Unify kthread_create_on_cpu() and kthread_create_worker_on_cpu() automatic format rcu: Use kthread preferred affinity for RCU boost kthread: Implement preferred affinity mm: Create/affine kswapd to its preferred node mm: Create/affine kcompactd to its preferred node kthread: Default affine kthread to its preferred NUMA node kthread: Make sure kthread hasn't started while binding it sched,arm64: Handle CPU isolation on last resort fallback rq selection arm64: Exclude nohz_full CPUs from 32bits el0 support lib: test_objpool: Use kthread_run_on_cpu() kallsyms: Use kthread_run_on_cpu() soc/qman: test: Use kthread_run_on_cpu() arm/bL_switcher: Use kthread_run_on_cpu()

2025-01-16ice: support FW Recovery ModeKonrad Knitter
Recovery Mode is intended to recover from a fatal failure scenario in which the device is not accessible to the host, meaning the firmware is non-responsive. The purpose of the Firmware Recovery Mode is to enable software tools to update firmware and/or device configuration so the fatal error can be resolved. Recovery Mode Firmware supports a limited set of admin commands required for NVM update. Recovery Firmware does not support hardware interrupts so a polling mode is used. The driver will expose only the minimum set of devlink commands required for the recovery of the adapter. Using an appropriate NVM image, the user can recover the adapter using the devlink flash API. Prior to 4.20 E810 Adapter Recovery Firmware supports only the update and erase of the "fw.mgmt" component. E810 Adapter Recovery Firmware doesn't support selected preservation of cards settings or identifiers. The following command can be used to recover the adapter: $ devlink dev flash <pci-address> <update-image.bin> component fw.mgmt overwrite settings overwrite identifier Newer FW versions (4.20 or newer) supports update of "fw.undi" and "fw.netlist" components. $ devlink dev flash <pci-address> <update-image.bin> Tested on Intel Corporation Ethernet Controller E810-C for SFP FW revision 3.20 and 4.30.

2025-01-14ice: Add in/out PTP pin delaysKarol Kolacinski
HW can have different input/output delays for each of the pins. Currently, only E82X adapters have delay compensation based on TSPLL config and E810 adapters have constant 1 ms compensation, both cases only for output delays and the same one for all pins. E825 adapters have different delays for SDP and other pins. Those delays are also based on direction and input delays are different than output ones. This is the main reason for moving delays to pin description structure. Add a field in ice_ptp_pin_desc structure to reflect that. Delay values are based on approximate calculations of HW delays based on HW spec. Implement external timestamp (input) delay compensation. Remove existing definitions and wrappers for periodic output propagation delays.

2025-01-14ice: implement low latency PHY timer updatesJacob Keller
Programming the PHY registers in preparation for an increment value change or a timer adjustment on E810 requires issuing Admin Queue commands for each PHY register. It has been found that the firmware Admin Queue processing occasionally has delays of tens or rarely up to hundreds of milliseconds. This delay cascades to failures in the PTP applications which depend on these updates being low latency. Consider a standard PTP profile with a sync rate of 16 times per second. This means there is ~62 milliseconds between sync messages. A complete cycle of the PTP algorithm 1) Sync message (with Tx timestamp) from source 2) Follow-up message from source 3) Delay request (with Tx timestamp) from sink 4) Delay response (with Rx timestamp of request) from source 5) measure instantaneous clock offset 6) request time adjustment via CLOCK_ADJTIME systemcall The Tx timestamps have a default maximum timeout of 10 milliseconds. If we assume that the maximum possible time is used, this leaves us with ~42 milliseconds of processing time for a complete cycle. The CLOCK_ADJTIME system call is synchronous and will block until the driver completes its timer adjustment or frequency change. If the writes to prepare the PHY timers get hit by a latency spike of 50 milliseconds, then the PTP application will be delayed past the point where the next cycle should start. Packets from the next cycle may have already arrived and are waiting on the socket. In particular, LinuxPTP ptp4l may start complaining about missing an announce message from the source, triggering a fault. In addition, the clockcheck logic it uses may trigger. This clockcheck failure occurs because the timestamp captured by hardware is compared against a reading of CLOCK_MONOTONIC. It is assumed that the time when the Rx timestamp is captured and the read from CLOCK_MONOTONIC are relatively close together. This is not the case if there is a significant delay to processing the Rx packet. Newer firmware supports programming the PHY registers over a low latency interface which bypasses the Admin Queue. Instead, software writes to the REG_LL_PROXY_L and REG_LL_PROXY_H registers. Firmware reads these registers and then programs the PHY timers. Implement functions to use this interface when available to program the PHY timers instead of using the Admin Queue. This avoids the Admin Queue latency and ensures that adjustments happen within acceptable latency bounds.

2025-01-14ice: add lock to protect low latency interfaceJacob Keller
Newer firmware for the E810 devices support a 'low latency' interface to interact with the PHY without using the Admin Queue. This is interacted with via the REG_LL_PROXY_L and REG_LL_PROXY_H registers. Currently, this interface is only used for Tx timestamps. There are two different mechanisms, including one which uses an interrupt for firmware to signal completion. However, these two methods are mutually exclusive, so no synchronization between them was necessary. This low latency interface is being extended in future firmware to support also programming the PHY timers. Use of the interface for PHY timers will need synchronization to ensure there is no overlap with a Tx timestamp. The interrupt-based response complicates the locking somewhat. We can't use a simple spinlock. This would require being acquired in ice_ptp_req_tx_single_tstamp, and released in ice_ptp_complete_tx_single_tstamp. The ice_ptp_req_tx_single_tstamp function is called from the threaded IRQ, and the ice_ptp_complete_tx_single_stamp is called from the low latency IRQ, so we would need to acquire the lock with IRQs disabled. To handle this, we'll use a wait queue along with wait_event_interruptible_locked_irq in the update flows which don't use the interrupt. The interrupt flow will acquire the wait queue lock, set the ATQBAL_FLAGS_INTR_IN_PROGRESS, and then initiate the firmware low latency request, and unlock the wait queue lock. Upon receipt of the low latency interrupt, the lock will be acquired, the ATQBAL_FLAGS_INTR_IN_PROGRESS bit will be cleared, and the firmware response will be captured, and wake_up_locked() will be called on the wait queue. The other flows will use wait_event_interruptible_locked_irq() to wait until the ATQBAL_FLAGS_INTR_IN_PROGRESS is clear. This function checks the condition under lock, but does not hold the lock while waiting. On return, the lock is held, and a return of zero indicates we hold the lock and the in-progress flag is not set. This will ensure that threads which need to use the low latency interface will sleep until they can acquire the lock without any pending low latency interrupt flow interfering.

The TS_LL_READ macros are used as part of the low latency Tx timestamp interface. A future firmware extension will add support for performing PHY timer updates over this interface. Using TS_LL_READ as the prefix for these macros will be confusing once the interface is used for other purposes. Rename the macros, using the prefix REG_LL_PROXY_H, to better clarify that this is for the low latency interface.

2025-01-14ice: add recipe priority check in searchMichal Swiatkowski
The new recipe should be added even if exactly the same recipe already exists with different priority. Example use case is when the rule is being added from TC tool context. It should has the highest priority, but if the recipe already exists the rule will inherit it priority. It can lead to the situation when the rule added from TC tool has lower priority than expected. The solution is to check the recipe priority when trying to find existing one. Previous recipe is still useful. Example: RID 8 -> priority 4 RID 10 -> priority 7 The difference is only in priority rest is let's say eth + mac + direction. Adding ARP + MAC_A + RX on RID 8, forward to VF0_VSI After that IP + MAC_B + RX on RID 10 (from TC tool), forward to PF0 Both will work. In case of adding ARP + MAC_A + RX on RID 8, forward to VF0_VSI ARP + MAC_A + RX on RID 10, forward to PF0. Only second one will match, but this is expected.

2025-01-07ice: fix incorrect PHY settings for 100 GB/sPrzemyslaw Korba
ptp4l application reports too high offset when ran on E823 device with a 100GB/s link. Those values cannot go under 100ns, like in a working case when using 100 GB/s cable. This is due to incorrect frequency settings on the PHY clocks for 100 GB/s speed. Changes are introduced to align with the internal hardware documentation, and correctly initialize frequency in PHY clocks with the frequency values that are in our HW spec. To reproduce the issue run ptp4l as a Time Receiver on E823 device, and observe the offset, which will never approach values seen in the PTP working case.

2024-12-11ice: cleanup Rx queue context programming functionsJacob Keller
The ice_copy_rxq_ctx_to_hw() and ice_write_rxq_ctx() functions perform some defensive checks which are typically frowned upon by kernel style guidelines. In particular, NULL checks on buffers which point to the stack are discouraged, especially when the functions are static and only called once. Checks of this sort only serve to hide potential programming error, as we will not produce the normal crash dump on a NULL access. In addition, ice_copy_rxq_ctx_to_hw() cannot fail in another way, so could be made void. Future support for VF Live Migration will need to introduce an inverse function for reading Rx queue context from HW registers to unpack it, as well as functions to pack and unpack Tx queue context from HW. Rather than copying these style issues into the new functions, lets first cleanup the existing code. For the ice_copy_rxq_ctx_to_hw() function: * Move the Rx queue index check out of this function. * Convert the function to a void return. * Use a simple int variable instead of a u8 for the for loop index, and initialize it inside the for loop. * Update the function description to better align with kernel doc style. For the ice_write_rxq_ctx() function: * Move the Rx queue index check into this function. * Update the function description with a Returns: to align with kernel doc style. These changes align the existing write functions to current kernel style, and will align with the style of the new functions added when we implement live migration in a future series.

2024-12-11ice: move prefetch enable to ice_setup_rx_ctxJacob Keller
The ice_write_rxq_ctx() function is responsible for programming the Rx Queue context into hardware. It receives the configuration in unpacked form via the ice_rlan_ctx structure. This function unconditionally modifies the context to set the prefetch enable bit. This was done by commit c31a5c25bb19 ("ice: Always set prefena when configuring an Rx queue"). Setting this bit makes sense, since prefetching descriptors is almost always the preferred behavior. However, the ice_write_rxq_ctx() function is not the place that actually defines the queue context. We initialize the Rx Queue context in ice_setup_rx_ctx(). It is surprising to have the Rx queue context changed by a function who's responsibility is to program the given context to hardware. Following the principle of least surprise, move the setting of the prefetch enable bit out of ice_write_rxq_ctx() and into the ice_setup_rx_ctx().

2024-12-11ice: reduce size of queue context fieldsJacob Keller
The ice_rlan_ctx and ice_tlan_ctx structures have some fields which are intentionally sized larger than necessary relative to the packed sizes the data must fit into. This was done because the original ice_set_ctx() function and its helpers did not correctly handle packing when the packed bits straddled a byte. This is no longer the case with the use of the <linux/packing.h> implementation. Save some bytes in these structures by sizing the variables to the number of bytes the actual bitpacked fields fit into. There are a couple of gaps left in the structure, which is a result of the fields being in the order they appear in the packed bit layout, but where alignment forces some extra gaps. We could fix this, saving ~8 bytes from each structure. However, these structures are not used heavily, and the resulting savings is minimal: $ bloat-o-meter ice-before-reorder.ko ice-after-reorder.ko add/remove: 0/0 grow/shrink: 1/1 up/down: 26/-70 (-44) Function old new delta ice_vsi_cfg_txq 1873 1899 +26 ice_setup_rx_ctx.constprop 1529 1459 -70 Total: Before=1459555, After=1459511, chg -0.00% Thus, the fields are left in the same order as the packed bit layout, despite the gaps this causes.

2024-12-11ice: use <linux/packing.h> for Tx and Rx queue context dataJacob Keller
The ice driver needs to write the Tx and Rx queue context when programming Tx and Rx queues. This is currently done using some bespoke custom logic via the ice_set_ctx() and its helper functions, along with bit position definitions in the ice_tlan_ctx_info and ice_rlan_ctx_info structures. This logic does work, but is problematic for several reasons: 1) ice_set_ctx requires a helper function for each byte size being packed, as it uses a separate function to pack u8, u16, u32, and u64 fields. This requires 4 functions which contain near-duplicate logic with the types changed out. 2) The logic in the ice_pack_ctx_word, ice_pack_ctx_dword, and ice_pack_ctx_qword does not handle values which straddle alignment boundaries very well. This requires that several fields in the ice_tlan_ctx_info and ice_rlan_ctx_info be a size larger than their bit size should require. 3) Future support for live migration will require adding unpacking functions to take the packed hardware context and unpack it into the ice_rlan_ctx and ice_tlan_ctx structures. Implementing this would require implementing ice_get_ctx, and its associated helper functions, which essentially doubles the amount of code required. The Linux kernel has had a packing library that can handle this logic since commit 554aae35007e ("lib: Add support for generic packing operations"). The library was recently extended with support for packing or unpacking an array of fields, with a similar structure as the ice_ctx_ele structure. Replace the ice-specific ice_set_ctx() logic with the recently added pack_fields and packed_field_s infrastructure from <linux/packing.h> For API simplicity, the Tx and Rx queue context are programmed using separate ice_pack_txq_ctx() and ice_pack_rxq_ctx(). This avoids needing to export the packed_field_s arrays. The functions can pointers to the appropriate ice_txq_ctx_buf_t and ice_rxq_ctx_buf_t types, ensuring that only buffers of the appropriate size are passed.

2024-12-11ice: use structures to keep track of queue context sizeJacob Keller
The ice Tx and Rx queue context are currently stored as arrays of bytes with defined size (ICE_RXQ_CTX_SZ and ICE_TXQ_CTX_SZ). The packed queue context is often passed to other functions as a simple u8 * pointer, which does not allow tracking the size. This makes the queue context API easy to misuse, as you can pass an arbitrary u8 array or pointer. Introduce wrapper typedefs which use a __packed structure that has the proper fixed size for the Tx and Rx context buffers. This enables the compiler to track the size of the value and ensures that passing the wrong buffer size will be detected by the compiler. The existing APIs do not benefit much from this change, however the wrapping structures will be used to simplify the arguments of new packing functions based on the recently introduced pack_fields API.
