2025-04-15net: stmmac: imx: use stmmac_pltfr_probe()Russell King (Oracle)1-12/+2
Using stmmac_pltfr_probe() simplifies the probe function. This will not only call plat_dat->init (imx_dwmac_init), but also plat_dat->exit (imx_dwmac_exit) appropriately if stmmac_dvr_probe() fails. This results in an overall simplification of the glue driver.

2025-04-15ixgbe: add support for FW rollback modeAndrii Staikov6-1/+66
The driver should detect whether the device entered FW rollback mode and then notify user with the dedicated message including FW and NVM versions. Even if the driver detected rollback mode, this should not result in an probe error and the normal flow proceeds. FW tries to rollback to "old" operational FW located in the inactive NVM bank in cases when newly loaded FW exhibits faulty behavior. If something goes wrong during boot the FW may switch into rollback mode in an attempt to avoid recovery mode and stay operational. After rollback is successful, the banks are swapped, and the "rollback" bank becomes the active bank for the next reset.

2025-04-15ixgbe: add support for devlink reloadJedrzej Jagielski7-7/+182
The E610 adapters contain an embedded chip with firmware which can be updated using devlink flash. The firmware which runs on this chip is referred to as the Embedded Management Processor firmware (EMP firmware). Activating the new firmware image currently requires that the system be rebooted. This is not ideal as rebooting the system can cause unwanted downtime. The EMP firmware itself can be reloaded by issuing a special update to the device called an Embedded Management Processor reset (EMP reset). This reset causes the device to reset and reload the EMP firmware. Implement support for devlink reload with the "fw_activate" flag. This allows user space to request the firmware be activated immediately.

2025-04-15ixgbe: add device flash update via devlinkJedrzej Jagielski8-1/+970
Use the pldmfw library to implement device flash update for the Intel ixgbe networking device driver specifically for E610 devices. This support uses the devlink flash update interface. Using the pldmfw library, the provided firmware file will be scanned for the three major components, "fw.undi" for the Option ROM, "fw.mgmt" for the main NVM module containing the primary device firmware, and "fw.netlist" containing the netlist module. The flash is separated into two banks, the active bank containing the running firmware, and the inactive bank which we use for update. Each module is updated in a staged process. First, the inactive bank is erased, preparing the device for update. Second, the contents of the component are copied to the inactive portion of the flash. After all components are updated, the driver signals the device to switch the active bank during the next EMP reset. With this implementation, basic flash update for the E610 hardware is supported.

Fix niu_try_msix() to not cause a fatal trap on sparc systems. Set PCI_DEV_FLAGS_MSIX_TOUCH_ENTRY_DATA_FIRST on the struct pci_dev to work around a bug in the hardware or firmware. For each vector entry in the msix table, niu chips will cause a fatal trap if any registers in that entry are read before that entries' ENTRY_DATA register is written to. Testing indicates writes to other registers are not sufficient to prevent the fatal trap, however the value does not appear to matter. This only needs to happen once after power up, so simply rebooting into a kernel lacking this fix will NOT cause the trap.

2025-04-15net/mlx5: HWS, Cleanup matcher action STE tableVlad Dogaru8-401/+87
Remove the matcher action STE implementation now that the code uses per-queue action STE pools. This also allows simplifying matcher code because it is now only handling a single type of RTC/STE. The matcher resize data is also going away. Matchers were saving old action STE data because the rules still used it, but now that data lives in the action STE pool and is no longer coupled to a matcher. Furthermore, matchers no longer need to rehash a due to action template addition. If a new action template needs more action STEs, we simply update the matcher's num_of_action_stes and future rules will allocate the correct number. Existing rules are unaffected by such an operation and can continue to use their existing action STEs. The range action was using the matcher action STE implementation, but there was no reason to do this other than the container fitting the purpose. Extract that information to a separate structure. Finally, stop dumping per-matcher information about action RTCs, because they no longer exist. A later patch in this series will add support for dumping action STE pools.

2025-04-15net/mlx5: HWS, Implement action STE poolVlad Dogaru7-1/+457
Implement a per-queue pool of action STEs that match STEs can link to, regardless of matcher. The code relies on hints to optimize whether a given rule is added to rx-only, tx-only or both. Correspondingly, action STEs need to be added to different RTC for ingress or egress paths. For rx-and-tx rules, the current rule implementation dictates that the offsets for a given rule must be the same in both RTCs. To avoid wasting STEs, each action STE pool element holds 3 pools: rx-only, tx-only, and rx-and-tx, corresponding to the possible values of the pool optimization enum. The implementation then chooses at rule creation / update which of these elements to allocate from. Each element holds multiple action STE tables, which wrap an RTC, an STE range, the logic to buddy-allocate offsets from the range, and an STC that allows match STEs to point to this table. When allocating offsets from an element, we iterate through available action STE tables and, if needed, create a new table. Similar to the previous implementation, this iteration does not free any resources. This is implemented in a subsequent patch.

Refactor the pool implementation to remove unused flags and clarify its usage. A pool represents a single range of STEs or STCs which are allocated at pool creation time. Pools are used under three patterns: 1. STCs are allocated one at a time from a global pool using a bitmap based implementation. 2. Action STEs are allocated in power-of-two blocks using a buddy algorithm. 3. Match STEs do not use allocation, since insertion into these tables is based on hashes or direct addressing. In such cases we use a pool only to create the STE range.

The pool implementation claimed to support multiple resources, but this does not really make sense in context. Callers always allocate a single STC or STE chunk of exactly the size provided. The code that handled multiple resources was unused (and likely buggy) due to the combination of flags passed by callers. Simplify the pool by having it handle a single resource. As a result of this simplification, chunks no longer contain a resource offset (there is now only one resource per pool), and the get_base_id functions no longer take a chunk parameter.

2025-04-15net/mlx5: HWS, Fix matcher action template attachVlad Dogaru5-24/+97
The procedure of attaching an action template to an existing matcher had a few issues: 1. Attaching accidentally overran the `at` array in bwc_matcher, which would result in memory corruption. This bug wasn't triggered, but it is possible to trigger it by attaching action templates beyond the initial buffer size of 8. Fix this by converting to a dynamically sized buffer and reallocating if needed. 2. Similarly, the `at` array inside the native matcher was never reallocated. Fix this the same as above. 3. The bwc layer treated any error in action template attach as a signal that the matcher should be rehashed to account for a larger number of action STEs. In reality, there are other unrelated errors that can arise and they should be propagated upstack. Fix this by adding a `need_rehash` output parameter that's orthogonal to error codes.

Since commit 8efbdbfa9938 ("net: stmmac: Initialize MAC_ONEUS_TIC_COUNTER register"), GMAC4/5 core code will set this register based on the rate of plat->stmmac_clk. This clock is fetched by devm_stmmac_probe_config_dt(), and plat->clk_ptp_rate will be set to its rate profided a "ptp_ref" clock is not provided. In any case, Marek's commit will set the effectual value of this register. Therefore, dwmac-intel-plat.c writing GMAC_1US_TIC_COUNTER serves no useful purpose and can be removed.
