2024-08-27wifi: iwlwifi: clear trans->state earlier upon errorEmmanuel Grumbach
When the firmware crashes, we first told the op_mode and only then, changed the transport's state. This is a problem if the op_mode's nic_error() handler needs to send a host command: it'll see that the transport's state still reflects that the firmware is alive. Today, this has no consequences since we set the STATUS_FW_ERROR bit and that will prevent sending host commands. iwl_fw_dbg_stop_restart_recording looks at this bit to know not to send a host command for example. To fix the hibernation, we needed to reset the firmware without having an error and checking STATUS_FW_ERROR to see whether the firmware is alive will no longer hold, so this change is necessary as well. Change the flow a bit. Change trans->state before calling the op_mode's nic_error() method and check trans->state instead of STATUS_FW_ERROR. This will keep the current behavior of iwl_fw_dbg_stop_restart_recording upon firmware error, and it'll allow us to call iwl_fw_dbg_stop_restart_recording safely even if STATUS_FW_ERROR is clear, but yet, the firmware is not alive.

2024-08-27wifi: rtw89: introduce chip support link number and driver MLO capabilityZong-Zhe Yang
Configure supported link number by chip. And, introduce driver capability flag for MLO. Driver should depend on runtime FW features and chip info to determine whether to set the MLO capability flag or not. Once the MLO flag is set, driver will consider/register/initialize things for MLO usages. However, we just add the driver MLO capability flag ahead and don't really set it. Then, we can start to tweak driver architecture for MLO. Some code should depend on this flag. And after tweaking driver architecture is done, we will set it based on runtime conditions as mentioned above. Besides, MLD number supported by HW should be chip supported mac_id number / chip supported link number Without driver MLO capability flag, we allocate stations based on supported mac_id number. With driver MLO capability flag, we allocate stations based on supported MLD number.

In the function dpaa_napi_del(), we execute the netif_napi_del() for each cpu, which is actually a high overhead operation because each call to netif_napi_del() contains a synchronize_net(), i.e. an RCU operation.

2024-08-26ice: remove unnecessary control queue cmd_buf arraysJacob Keller
The driver allocates a cmd_buf array in addition to the desc_buf array. This array stores an ice_sq_cd command details structure for each entry in the control queue ring. The contents of the structure are copied from the value passed in via ice_sq_send_cmd, and include only a pointer to storage for the write back descriptor contents. Originally this array was intended to support asynchronous completion including features such as a callback function. This support was never implemented. All that exists today is needless copying and resetting of a cmd_buf array that is otherwise functionally unused. Since we do not plan to implement asynchronous completions, drop this unnecessary memory and logic. This saves memory for each control queue, and avoids the pointless copying and memset.

2024-08-26ice: stop intermixing AQ commands/responses debug dumpsPrzemek Kitszel
The ice_debug_cq() function is called to generate a debug log of control queue messages both sent and received. It currently does this over a potential total of 6 different printk invocations. The main logic prints over 4 calls to ice_debug(): 1. The metadata including opcode, flags, datalength and return value. 2. The cookie in the descriptor. 3. The parameter values. 4. The address for the databuffer. In addition, if the descriptor has a data buffer, it can be logged with two additional prints: 5. A message indicating the start of the data buffer. 6. The actual data buffer, printed using print_hex_dump_debug. This can lead to trouble in the event that two different PFs are logging messages. The messages become intermixed and it may not be possible to determine which part of the output belongs to which control queue message. To fix this, it needs to be possible to unambiguously determine which messages belong together. This is trivial for the messages that comprise the main printing. Combine them together into a single invocation of ice_debug(). The message containing a hex-dump of the data buffer is a bit more complicated. This is printed separately as part of print_hex_dump_debug. This function takes a prefix, which is currently always set to KBUILD_MODNAME. Extend this prefix to include the buffer address for the databuffer, which is printed as part of the main print, and which is guaranteed to be unique for each buffer. Refactor the ice_debug_array(), introducing an ice_debug_array_w_prefix(). Build the prefix by combining KBUILD_MODNAME with the databuffer address using snprintf(). These changes make it possible to unambiguously determine what data belongs to what control queue message.

2024-08-26ice: improve debug print for control queue messagesJacob Keller
The ice_debug_cq function is called to print debug data for a control queue descriptor in multiple places. This includes both before we send a message on a transmit queue, after the writeback completion of a message on the transmit queue, and when we receive a message on a receive queue. This function does not include data about *which* control queue the message is on, nor whether it was what we sent to the queue or what we received from the queue. Modify ice_debug_cq to take two extra parameters, a pointer to the control queue and a boolean indicating if this was a response or a command. Improve the debug messages by replacing "CQ CMD" with a string indicating which specific control queue (based on cq->qtype) and whether this was a command sent by the PF or a response from the queue. This helps make the log output easier to understand and consume when debugging.

2024-08-26ice: implement and use rd32_poll_timeout for ice_sq_done timeoutJacob Keller
The ice_sq_done function is used to check the control queue head register and determine whether or not the control queue processing is done. This function is called in a loop checking against jiffies for a specified timeout. The pattern of reading a register in a loop until a condition is true or a timeout is reached is a relatively common pattern. In fact, the kernel provides a read_poll_timeout function implementing this behavior in <linux/iopoll.h> Use of read_poll_timeout is preferred over directly coding these loops. However, using it in the ice driver is a bit more difficult because of the rd32 wrapper. Implement a rd32_poll_timeout wrapper based on read_poll_timeout. Refactor ice_sq_done to use rd32_poll_timeout, replacing the loop calling ice_sq_done in ice_sq_send_cmd. This simplifies the logic down to a single ice_sq_done() call. The implementation of rd32_poll_timeout uses microseconds for its timeout value, so update the CQ timeout macros used to be specified in microseconds units as well instead of using HZ for jiffies.

2024-08-26phy: dp83td510: Utilize ALCD for cable length measurement when link is activeOleksij Rempel
In industrial environments where 10BaseT1L PHYs are replacing existing field bus systems like CAN, it's often essential to retain the existing cable infrastructure. After installation, collecting metrics such as cable length is crucial for assessing the quality of the infrastructure. Traditionally, TDR (Time Domain Reflectometry) is used for this purpose. However, TDR requires interrupting the link, and if the link partner remains active, the TDR measurement will fail. Unlike multi-pair systems, where TDR can be attempted during the MDI-X switching window, 10BaseT1L systems face greater challenges. The TDR sequence on 10BaseT1L is longer and coincides with uninterrupted autonegotiation pulses, making TDR impossible when the link partner is active. The DP83TD510 PHY provides an alternative through ALCD (Active Link Cable Diagnostics), which allows for cable length measurement without disrupting an active link. Since a live link indicates no short or open cable states, ALCD can be used effectively to gather cable length information. Enhance the dp83td510 driver by: - Leveraging ALCD to measure cable length when the link is active. - Bypassing TDR when a link is detected, as ALCD provides the required information without disruption.

2024-08-26wifi: iwlwifi: mvm: don't wait for tx queues if firmware is deadEmmanuel Grumbach
There is a WARNING in iwl_trans_wait_tx_queues_empty() (that was recently converted from just a message), that can be hit if we wait for TX queues to become empty after firmware died. Clearly, we can't expect anything from the firmware after it's declared dead. Don't call iwl_trans_wait_tx_queues_empty() in this case. While it could be a good idea to stop the flow earlier, the flush functions do some maintenance work that is not related to the firmware, so keep that part of the code running even when the firmware is not running.

2024-08-26wifi: iwlwifi: mvm: fix hibernationEmmanuel Grumbach
Fast resume is a feature that was recently introduced to speed up the resume time. It basically keeps the firmware alive while the system is suspended and that avoids starting again the whole device. This flow can't work for hibernation, since when the system boots, before the frozen image is loaded, the kernel may touch the device. As a result, we can't assume the device is in the exact same state as before the hibernation. Detect that we are resuming from hibernation through the PCI device and forbid the fast resume flow. We also need to shut down the device cleanly when that happens. In addition, in case the device is power gated during S3, we won't be able to keep the device alive. Detect this situation with BE200 at least with the help of the CSR_FUNC_SCRATCH register and reset the device upon resume if it was power gated during S3.

2024-08-23net: mana: Fix race of mana_hwc_post_rx_wqe and new hwc responseHaiyang Zhang
The mana_hwc_rx_event_handler() / mana_hwc_handle_resp() calls complete(&ctx->comp_event) before posting the wqe back. It's possible that other callers, like mana_create_txq(), start the next round of mana_hwc_send_request() before the posting of wqe. And if the HW is fast enough to respond, it can hit no_wqe error on the HW channel, then the response message is lost. The mana driver may fail to create queues and open, because of waiting for the HW response and timed out. Sample dmesg: [ 528.610840] mana 39d4:00:02.0: HWC: Request timed out!
