2025-09-14amd-xgbe: Add PPS periodic output supportRaju Rangoju
Add support for hardware PPS (Pulse Per Second) output to the AMD XGBE driver. The implementation enables flexible periodic output mode, exposing it via the PTP per_out interface. The driver supports configuring PPS output using the standard PTP subsystem, allowing precise periodic signal generation for time synchronization applications. The feature has been verified using the testptp tool and oscilloscope.

2025-09-14qed: Don't collect too many protection override GRC elementsJamie Bainbridge
In the protection override dump path, the firmware can return far too many GRC elements, resulting in attempting to write past the end of the previously-kmalloc'ed dump buffer. This will result in a kernel panic with reason: BUG: unable to handle kernel paging request at ADDRESS where "ADDRESS" is just past the end of the protection override dump buffer. The start address of the buffer is: p_hwfn->cdev->dbg_features[DBG_FEATURE_PROTECTION_OVERRIDE].dump_buf and the size of the buffer is buf_size in the same data structure. The panic can be arrived at from either the qede Ethernet driver path: [exception RIP: qed_grc_dump_addr_range+0x108] qed_protection_override_dump at ffffffffc02662ed [qed] qed_dbg_protection_override_dump at ffffffffc0267792 [qed] qed_dbg_feature at ffffffffc026aa8f [qed] qed_dbg_all_data at ffffffffc026b211 [qed] qed_fw_fatal_reporter_dump at ffffffffc027298a [qed] devlink_health_do_dump at ffffffff82497f61 devlink_health_report at ffffffff8249cf29 qed_report_fatal_error at ffffffffc0272baf [qed] qede_sp_task at ffffffffc045ed32 [qede] process_one_work at ffffffff81d19783 or the qedf storage driver path: [exception RIP: qed_grc_dump_addr_range+0x108] qed_protection_override_dump at ffffffffc068b2ed [qed] qed_dbg_protection_override_dump at ffffffffc068c792 [qed] qed_dbg_feature at ffffffffc068fa8f [qed] qed_dbg_all_data at ffffffffc0690211 [qed] qed_fw_fatal_reporter_dump at ffffffffc069798a [qed] devlink_health_do_dump at ffffffff8aa95e51 devlink_health_report at ffffffff8aa9ae19 qed_report_fatal_error at ffffffffc0697baf [qed] qed_hw_err_notify at ffffffffc06d32d7 [qed] qed_spq_post at ffffffffc06b1011 [qed] qed_fcoe_destroy_conn at ffffffffc06b2e91 [qed] qedf_cleanup_fcport at ffffffffc05e7597 [qedf] qedf_rport_event_handler at ffffffffc05e7bf7 [qedf] fc_rport_work at ffffffffc02da715 [libfc] process_one_work at ffffffff8a319663 Resolve this by clamping the firmware's return value to the maximum number of legal elements the firmware should return.

2025-09-14net: fec: enable the Jumbo frame support for i.MX8QMShenwei Wang
Certain i.MX SoCs, such as i.MX8QM and i.MX8QXP, feature enhanced FEC hardware that supports Ethernet Jumbo frames with packet sizes up to 16K bytes. When Jumbo frames are supported, the TX FIFO may not be large enough to hold an entire frame. To handle this, the FIFO is configured to operate in cut-through mode when the frame size exceeds (PKT_MAXBUF_SIZE - ETH_HLEN - ETH_FCS_LEN), which allows transmission to begin once the FIFO reaches a certain threshold.

Add a fec_change_mtu() handler to recalculate the pagepool_order based on the new_mtu value. And update the rx_frame_size accordingly when pagepool_order changes. MTU changes are only allowed when the adater is not running.

2025-09-14net: fec: add rx_frame_size to support configurable RX lengthShenwei Wang
Add a new rx_frame_size member in the fec_enet_private structure to track the RX buffer size. On the Jumbo frame enabled system, the value will be recalculated whenever the MTU is updated, allowing the driver to allocate RX buffer efficiently. Configure the TRUNC_FL (Frame Truncation Length) based on the smaller value between max_buf_size and the rx_frame_size to maintain consistent RX error behavior, regardless of whether Jumbo frames are enabled.
