2025-07-11wifi: ath12k: Fix packets received in WBM error ring with REO LUT enabledNithyanantham Paramasivam
Currently, packets are being received into the WBM error ring when REO queue lookup is enabled, resulting in degraded RX performance. The issue arises because the REO queue LUT TID memory reference is set to zero-it's being assigned before the memory is allocated. Fix this by assigning the REO queue TID memory reference in the LUT immediately after memory allocation to ensure correct packet processing.

2025-07-11net: ll_temac: Fix missing tx_pending check in ethtools_set_ringparam()Alok Tiwari
The function ll_temac_ethtools_set_ringparam() incorrectly checked rx_pending twice, once correctly for RX and once mistakenly in place of tx_pending. This caused tx_pending to be left unchecked against TX_BD_NUM_MAX. As a result, invalid TX ring sizes may have been accepted or valid ones wrongly rejected based on the RX limit, leading to potential misconfiguration or unexpected results. This patch corrects the condition to properly validate tx_pending.

2025-07-11net/mlx5e: Add new prio for promiscuous modeJianbo Liu
An optimization for promiscuous mode adds a high-priority steering table with a single catch-all rule to steer all traffic directly to the TTC table. However, a gap exists between the creation of this table and the insertion of the catch-all rule. Packets arriving in this brief window would miss as no rule was inserted yet, unnecessarily incrementing the 'rx_steer_missed_packets' counter and dropped. This patch resolves the issue by introducing a new prio for this table, placing it between MLX5E_TC_PRIO and MLX5E_NIC_PRIO. By doing so, packets arriving during the window now fall through to the next prio (at MLX5E_NIC_PRIO) instead of being dropped.

2025-07-11net/mlx5e: Fix race between DIM disable and net_dim()Carolina Jubran
There's a race between disabling DIM and NAPI callbacks using the dim pointer on the RQ or SQ. If NAPI checks the DIM state bit and sees it still set, it assumes `rq->dim` or `sq->dim` is valid. But if DIM gets disabled right after that check, the pointer might already be set to NULL, leading to a NULL pointer dereference in net_dim(). Fix this by calling `synchronize_net()` before freeing the DIM context. This ensures all in-progress NAPI callbacks are finished before the pointer is cleared.

2025-07-11bus: imx-aipstz: allow creating pdevs for child busesLaurentiu Mihalcea
devm_of_platform_populate() passes a NULL as the bus OF match table to the underlying of_platform_populate(), meaning child bus devices of the AIPSTZ bridge will not have its children devices created. Since some SoCs (e.g. i.MX8MP) use this particular setup (e.g. SPBA bus, which is a child of AIPSTZ5 and has multiple child nodes), the driver needs to support it. Therefore, replace devm_of_platform_populate() with of_platform_populate() and pass a reference to the bus OF match table to it. For now, the only possible child buses are simple buses. Since the usage of devres is dropped, the complementary operation of of_platform_populate() needs to be called during the driver's removal.

2025-07-10drm/xe/guc: Default log level to non-verboseLucas De Marchi
Currently xe sets the guc log level to a verbose level since it's useful to debug hangs and general development. However the verbose level may already be too much and affect performance. Michal Mrozek did some tests with the L0 compute stack for submission latency with ULLS disabled. Below are the normalized numbers with log level 3 (the current default) as baseline for each test: Test \ Log Level 3 0 1 2 ----------------------------------------------------------- ------ ------ ------ ------ BestWalkerNthCommandListSubmission(CmdListCount=2) 1.00 0.63 0.63 0.96 BestWalkerNthSubmission(KernelCount=2) 1.00 0.62 0.63 0.96 BestWalkerNthSubmissionImmediate(KernelCount=2) 1.00 0.58 0.58 0.85 BestWalkerSubmission 1.00 0.62 0.62 0.96 BestWalkerSubmissionImmediate 1.00 0.63 0.62 0.96 BestWalkerSubmissionImmediateMultiCmdlists(cmdlistCount=2) 1.00 0.58 0.58 0.86 BestWalkerSubmissionImmediateMultiCmdlists(cmdlistCount=4) 1.00 0.70 0.70 0.83 BestWalkerSubmissionImmediateMultiCmdlists(cmdlistCount=8) 1.00 0.53 0.52 0.78 Log level 2 is the first "verbose level" for GuC, where the biggest difference happens.

2025-07-10net: phy: microchip: limit 100M workaround to link-down events on LAN88xxOleksij Rempel
Restrict the 100Mbit forced-mode workaround to link-down transitions only, to prevent repeated link reset cycles in certain configurations. The workaround was originally introduced to improve signal reliability when switching cables between long and short distances. It temporarily forces the PHY into 10 Mbps before returning to 100 Mbps. However, when used with autonegotiating link partners (e.g., Intel i350), executing this workaround on every link change can confuse the partner and cause constant renegotiation loops. This results in repeated link down/up transitions and the PHY never reaching a stable state. Limit the workaround to only run during the PHY_NOLINK state. This ensures it is triggered only once per link drop, avoiding disruptive toggling while still preserving its intended effect. Note: I am not able to reproduce the original issue that this workaround addresses. I can only confirm that 100 Mbit mode works correctly in my test setup. Based on code inspection, I assume the workaround aims to reset some internal state machine or signal block by toggling speeds. However, a PHY reset is already performed earlier in the function via phy_init_hw(), which may achieve a similar effect. Without a reproducer, I conservatively keep the workaround but restrict its conditions.

2025-07-10net: phy: microchip: Use genphy_soft_reset() to purge stale LPA bitsOleksij Rempel
Enable .soft_reset for the LAN88xx PHY driver by assigning genphy_soft_reset() to ensure that the phylib core performs a proper soft reset during reconfiguration. Previously, the driver left .soft_reset unimplemented, so calls to phy_init_hw() (e.g., from lan88xx_link_change_notify()) did not fully reset the PHY. As a result, stale contents in the Link Partner Ability (LPA) register could persist, causing the PHY to incorrectly report that the link partner advertised autonegotiation even when it did not. Using genphy_soft_reset() guarantees a clean reset of the PHY and corrects the false autoneg reporting in these scenarios.

2025-07-10ibmvnic: Fix hardcoded NUM_RX_STATS/NUM_TX_STATS with dynamic sizeofMingming Cao
The previous hardcoded definitions of NUM_RX_STATS and NUM_TX_STATS were not updated when new fields were added to the ibmvnic_{rx,tx}_queue_stats structures. Specifically, commit 2ee73c54a615 ("ibmvnic: Add stat for tx direct vs tx batched") added a fourth TX stat, but NUM_TX_STATS remained 3, leading to a mismatch. This patch replaces the static defines with dynamic sizeof-based calculations to ensure the stat arrays are correctly sized.

The function opencodes the for_each_cpu_from() by using an open for-loop. Fix that in sake of readability. While there, drop the 'valid' variable as it's pretty useless here.

2025-07-10regulator: tps6594-regulator: Add TI TPS652G1 PMIC regulatorsMichael Walle
The TI TPS652G1 is a stripped down version of the TPS65224 PMIC. It doesn't feature the multiphase buck converter nor any voltage monitoring. Due to the latter there are no interrupts serviced. In case of the TPS652G1 any interrupt related setup is just skipped.

2025-07-10regulator: tps6594-regulator: refactor variant descriptionsMichael Walle
Instead of using conditionals or tri state operators throughout the .probe() provide a description per variant. This will make it much easier to add new variants later. While at it, make the variable naming more consistent. This patch is only compile-time tested.

2025-07-10regulator: tps6594-regulator: remove hardcoded buck configMichael Walle
Commit 00c826525fba ("regulator: tps6594-regulator: Add TI TPS65224 PMIC regulators") added support for the TPS65224 and made the description of the multi-phase buck converter variable depending on the variant of the PMIC. But this was just done for MUTLI_BUCK12 and MULTI_BUCK12_34 configs probably because this variant only supports a multi-phase configuration on buck 1 and 2. Remove the hardcoded value for the remaining two configs, too as future PMIC variants might also support these. This is a preparation patch to refactor the regulator description and is compile-time only tested.

2025-07-10regulator: tps6594-regulator: remove interrupt_countMichael Walle
In .probe() interrupt_count and nr_types is essentially the same. It contains the number of different interrupt per LDO or buck converter. Drop one. This is a preparation patch to further simplify the handling of different variants of this PMIC. This patch is only compile-time tested.
