2025-01-08net: hns3: fixed hclge_fetch_pf_reg accesses bar space out of bounds issueHao Lan
The TQP BAR space is divided into two segments. TQPs 0-1023 and TQPs 1024-1279 are in different BAR space addresses. However, hclge_fetch_pf_reg does not distinguish the tqp space information when reading the tqp space information. When the number of TQPs is greater than 1024, access bar space overwriting occurs. The problem of different segments has been considered during the initialization of tqp.io_base. Therefore, tqp.io_base is directly used when the queue is read in hclge_fetch_pf_reg.

2025-01-08net: hns3: Resolved the issue that the debugfs query result is inconsistent.Hao Lan
This patch modifies the implementation of debugfs: When the user process stops unexpectedly, not all data of the file system is read. In this case, the save_buf pointer is not released. When the user process is called next time, save_buf is used to copy the cached data to the user space. As a result, the queried data is stale. To solve this problem, this patch implements .open() and .release() handler for debugfs file_operations. moving allocation buffer and execution of the cmd to the .open() handler and freeing in to the .release() handler. Allocate separate buffer for each reader and associate the buffer with the file pointer. When different user read processes no longer share the buffer, the stale data problem is fixed.

2025-01-08net: hns3: fixed reset failure issues caused by the incorrect reset typeHao Lan
When a reset type that is not supported by the driver is input, a reset pending flag bit of the HNAE3_NONE_RESET type is generated in reset_pending. The driver does not have a mechanism to clear this type of error. As a result, the driver considers that the reset is not complete.

2025-01-07igc: return early when failing to read EECD registerEn-Wei Wu
When booting with a dock connected, the igc driver may get stuck for ~40 seconds if PCIe link is lost during initialization. This happens because the driver access device after EECD register reads return all F's, indicating failed reads. Consequently, hw->hw_addr is set to NULL, which impacts subsequent rd32() reads. This leads to the driver hanging in igc_get_hw_semaphore_i225(), as the invalid hw->hw_addr prevents retrieving the expected value. To address this, a validation check and a corresponding return value catch is added for the EECD register read result. If all F's are returned, indicating PCIe link loss, the driver will return -ENXIO immediately. This avoids the 40-second hang and significantly improves boot time when using a dock with an igc NIC.

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. Reproduction output: ptp4l -i enp137s0f3 -m -2 -s -f /etc/ptp4l_8275.conf ptp4l[5278.775]: master offset 12470 s2 freq +41288 path delay -3002 ptp4l[5278.837]: master offset 10525 s2 freq +39202 path delay -3002 ptp4l[5278.900]: master offset -24840 s2 freq -20130 path delay -3002 ptp4l[5278.963]: master offset 10597 s2 freq +37908 path delay -3002 ptp4l[5279.025]: master offset 8883 s2 freq +36031 path delay -3002 ptp4l[5279.088]: master offset 7267 s2 freq +34151 path delay -3002 ptp4l[5279.150]: master offset 5771 s2 freq +32316 path delay -3002 ptp4l[5279.213]: master offset 4388 s2 freq +30526 path delay -3002 ptp4l[5279.275]: master offset -30434 s2 freq -28485 path delay -3002 ptp4l[5279.338]: master offset -28041 s2 freq -27412 path delay -3002 ptp4l[5279.400]: master offset 7870 s2 freq +31118 path delay -3002 Fixes: 3a7496234d17 ("ice: implement basic E822 PTP support") Reviewed-by: Milena Olech <milena.olech@intel.com> Signed-off-by: Przemyslaw Korba <przemyslaw.korba@intel.com> Tested-by: Rinitha S <sx.rinitha@intel.com> (A Contingent worker at Intel) Signed-off-by: Tony Nguyen <anthony.l.nguyen@intel.com>

2025-01-06bnxt_en: Fix DIM shutdownMichael Chan
DIM work will call the firmware to adjust the coalescing parameters on the RX rings. We should cancel DIM work before we call the firmware to free the RX rings. Otherwise, FW will reject the call from DIM work if the RX ring has been freed. This will generate an error message like this: bnxt_en 0000:21:00.1 ens2f1np1: hwrm req_type 0x53 seq id 0x6fca error 0x2 and cause unnecessary concern for the user. It is also possible to modify the coalescing parameters of the wrong ring if the ring has been re-allocated. To prevent this, cancel DIM work right before freeing the RX rings. We also have to add a check in NAPI poll to not schedule DIM if the RX rings are shutting down. Check that the VNIC is active before we schedule DIM. The VNIC is always disabled before we free the RX rings.

2025-01-04net: libwx: fix firmware mailbox abnormal returnJiawen Wu
The existing SW-FW interaction flow on the driver is wrong. Follow this wrong flow, driver would never return error if there is a unknown command. Since firmware writes back 'firmware ready' and 'unknown command' in the mailbox message if there is an unknown command sent by driver. So reading 'firmware ready' does not timeout. Then driver would mistakenly believe that the interaction has completed successfully. It tends to happen with the use of custom firmware. Move the check for 'unknown command' out of the poll timeout for 'firmware ready'. And adjust the debug log so that mailbox messages are always printed when commands timeout.

2025-01-03net: ti: icssg-prueth: Fix clearing of IEP_CMP_CFG registers during iep_initMeghana Malladi
When ICSSG interfaces are brought down and brought up again, the pru cores are shut down and booted again, flushing out all the memories and start again in a clean state. Hence it is expected that the IEP_CMP_CFG register needs to be flushed during iep_init() to ensure that the existing residual configuration doesn't cause any unusual behavior. If the register is not cleared, existing IEP_CMP_CFG set for CMP1 will result in SYNC0_OUT signal based on the SYNC_OUT register values. After bringing the interface up, calling PPS enable doesn't work as the driver believes PPS is already enabled, (iep->pps_enabled is not cleared during interface bring down) and driver will just return true even though there is no signal. Fix this by disabling pps and perout.

2025-01-03net: ti: icssg-prueth: Fix firmware load sequence.MD Danish Anwar
Timesync related operations are ran in PRU0 cores for both ICSSG SLICE0 and SLICE1. Currently whenever any ICSSG interface comes up we load the respective firmwares to PRU cores and whenever interface goes down, we stop the resective cores. Due to this, when SLICE0 goes down while SLICE1 is still active, PRU0 firmwares are unloaded and PRU0 core is stopped. This results in clock jump for SLICE1 interface as the timesync related operations are no longer running. As there are interdependencies between SLICE0 and SLICE1 firmwares, fix this by running both PRU0 and PRU1 firmwares as long as at least 1 ICSSG interface is up. Add new flag in prueth struct to check if all firmwares are running and remove the old flag (fw_running). Use emacs_initialized as reference count to load the firmwares for the first and last interface up/down. Moving init_emac_mode and fw_offload_mode API outside of icssg_config to icssg_common_start API as they need to be called only once per firmware boot. Change prueth_emac_restart() to return error code and add error prints inside the caller of this functions in case of any failures. Move prueth_emac_stop() from common to sr1 driver. sr1 and sr2 drivers have different logic handling for stopping the firmwares. While sr1 driver is dependent on emac structure to stop the corresponding pru cores for that slice, for sr2 all the pru cores of both the slices are stopped and is not dependent on emac. So the prueth_emac_stop() function is no longer common and can be moved to sr1 driver.

ipc_mmio_init() used the post-decrement operator in its loop continuing condition of "retries" counter being "> 0", which meant that when this condition caused loop exit "retries" counter reached -1. But the later valid exec stage failure check only tests for "retries" counter being exactly zero, so it didn't trigger in this case (but would wrongly trigger if the code reaches a valid exec stage in the very last loop iteration).

2025-01-02xe/oa: Fix query mode of operation for OAR/OACUmesh Nerlige Ramappa
This is a set of squashed commits to facilitate smooth applying to stable. Each commit message is retained for reference. 1) Allow a GGTT mapped batch to be submitted to user exec queue For a OA use case, one of the HW registers needs to be modified by submitting an MI_LOAD_REGISTER_IMM command to the users exec queue, so that the register is modified in the user's hardware context. In order to do this a batch that is mapped in GGTT, needs to be submitted to the user exec queue. Since all user submissions use q->vm and hence PPGTT, add some plumbing to enable submission of batches mapped in GGTT. v2: ggtt is zero-initialized, so no need to set it false (Matt Brost) 2) xe/oa: Use MI_LOAD_REGISTER_IMMEDIATE to enable OAR/OAC To enable OAR/OAC, a bit in RING_CONTEXT_CONTROL needs to be set. Setting this bit cause the context image size to change and if not done correct, can cause undesired hangs. Current code uses a separate exec_queue to modify this bit and is error-prone. As per HW recommendation, submit MI_LOAD_REGISTER_IMM to the target hardware context to modify the relevant bit. In v2 version, an attempt to submit everything to the user-queue was made, but it failed the unprivileged-single-ctx-counters test. It appears that the OACTXCONTROL must be modified from a remote context. In v3 version, all context specific register configurations were moved to use LOAD_REGISTER_IMMEDIATE and that seems to work well. This is a cleaner way, since we can now submit all configuration to user exec_queue and the fence handling is simplified. v2: (Matt) - set job->ggtt to true if create job is successful - unlock vm on job error (Ashutosh) - don't wait on job submission - use kernel exec queue where possible v3: (Ashutosh) - Fix checkpatch issues - Remove extra spaces/new-lines - Add Fixes: and Cc: tags - Reset context control bit when OA stream is closed - Submit all config via MI_LOAD_REGISTER_IMMEDIATE (Umesh) - Update commit message for v3 experiment - Squash patches for easier port to stable v4: (Ashutosh) - No need to pass q to xe_oa_submit_bb - Do not support exec queues with width > 1 - Fix disabling of CTX_CTRL_OAC_CONTEXT_ENABLE v5: (Ashutosh) - Drop reg_lri related comments - Use XE_OA_SUBMIT_NO_DEPS in xe_oa_load_with_lri Fixes: 8135f1c09dd2 ("drm/xe/oa: Don't reset OAC_CONTEXT_ENABLE on OA stream close") Signed-off-by: Umesh Nerlige Ramappa <umesh.nerlige.ramappa@intel.com> Reviewed-by: Matthew Brost <matthew.brost@intel.com> # commit 1 Reviewed-by: Ashutosh Dixit <ashutosh.dixit@intel.com> Cc: stable@vger.kernel.org Reviewed-by: Jonathan Cavitt <jonathan.cavitt@intel.com> Signed-off-by: Ashutosh Dixit <ashutosh.dixit@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20241220171919.571528-2-umesh.nerlige.ramappa@intel.com (cherry picked from commit 55039832f98c7e05f1cf9e0d8c12b2490abd0f16) Signed-off-by: Thomas Hellström <thomas.hellstrom@linux.intel.com>

Removed bnxt_re_modify_qp() call from bnxt_re_dev_stop() as it is a no-op.

Move the declaration of the 'ib_sge list' variable outside the 'always_invalidate' block to ensure it remains accessible for use throughout the function.

2024-12-30gve: trigger RX NAPI instead of TX NAPI in gve_xsk_wakeupJoshua Washington
Commit ba0925c34e0f ("gve: process XSK TX descriptors as part of RX NAPI") moved XSK TX processing to be part of the RX NAPI. However, that commit did not include triggering the RX NAPI in gve_xsk_wakeup. This is necessary because the TX NAPI only processes TX completions, meaning that a TX wakeup would not actually trigger XSK descriptor processing. Also, the branch on XDP_WAKEUP_TX was supposed to have been removed, as the NAPI should be scheduled whether the wakeup is for RX or TX.
