In MSIX mode the number of irq depends on the number of possible cpus existing on the host. This cause to bug in case there are offline cores. Take into account only the online CPUs instead. Also save it in temporary variable. Fixes: commit 2e5d4a8f ("iwlwifi: pcie: Add new configuration to enable MSIX") Signed-off-by:

In order to utilize the host's CPUs in the most efficient way we bind each rx interrupt vector to each CPU on the host. Each rx interrupt is prioritized to execute only on the designated CPU rather than any CPU. Processor affinity takes advantage of the fact that some remnants of a process that was run on a given processor may remain in that processor's memory state for example, data in the CPU cache after another process is run on that CPU. Scheduling that process to execute on the same processor could result in an efficient use of process by reducing performance-degrading situations such as cache misses and parallel processing.

When a STA is removed in DQA mode, if no traffic went through its reserved queue, the txq continues to be marked as reserved and no STA can use it. Make sure that in such a case the reserved queue is marked as free when the STA is removed. Fixes: commit 24afba76 ("iwlwifi: mvm: support bss dynamic alloc/dealloc of queues") Signed-off-by:

In iwl_mvm_rx_tx_cmd_single(), when checking if a given TID is aggregated, the driver doesn't check whether or not the queue itself can be aggregated. For example, a management queue might be marked as aggregated if TID 0 is aggregated on a (different) data queue. Make sure that mgmt frames are sent with TID IWL_TID_NON_QOS, and in this way make sure no mixups of this sort happen.

In case the OS provides fewer interrupts than requested, different causes will share the same interrupt vector as follow: 1.One interrupt less: non rx causes shared with FBQ. 2.Two interrupts less: non rx causes shared with FBQ and RSS. 3.More than two interrupts: we will use fewer RSS queues. Also make the request depend on the number of online CPUs instead of possible CPUs. Signed-off-by:

The original intent was to have the general iwl_queue shared between RX and TX queues, but it is not the actual status. Since it is not shared with any struct but iwl_txq, it adds unnecessary complexity. Merge those structs. Signed-off-by:

In a000 devices we have 15 fifos, so in the shared memory config the number of tx fifos in the array was changed accordingly. As it is in the middle of the struct, the parsing code needs to be duplicated. To minimize the duplication, do not save variables we never actually use. Signed-off-by:

Since the SCD_QUEUE_CFG command was introduced the driver calls iwl_trans_txq_enable_cfg() with a NULL for scd_cfg parameter. This makes the transport avoid writing to the SCD pointers, since it can cause races with firmware, which is also accessing the registers. The transport only updates the write pointer in that case. Fix a wrong call to iwl_trans_txq_enable() which caused a scd_cfg parameter to be sent to transport, resulting with an access to SCD registers.

Every active TXQ is assigned to a TID given through the SCD_CONFIG_CMD, and acts as an identifier in the FW. However, there may be cases this ownership needs to be changed. For example, in the following scenario: 1. TID x is owner of a queue 2. Due to a shortage of queues, TID y and z share with x 3. TID x becomes inactive and needs to be removed from the shared queue. In this scenario, if another queue is freed and traffic on x continues, we can't allocate it a new queue as long as it is the owner of the first queue. Support moving ownership of a TXQ to a different TID (same STA) without stopping the queue. Signed-off-by: -

When working in DQA mode, if a queue is shared and a HW restart occurs, there might be a possible race condition between stations on the queues, and an existing queue might be left with no queues. To solve this, make sure in DQA mode to re-assign the same queues as before the HW restart. Signed-off-by:

Tom Herbert says: ==================== strp: Stream parser for messages This patch set introduces a utility for parsing application layer protocol messages in a TCP stream. This is a generalization of the mechanism implemented of Kernel Connection Multiplexor. This patch set adapts KCM to use the strparser. We expect that kTLS can use this mechanism also. RDS would probably be another candidate to use a common stream parsing mechanism. The API includes a context structure, a set of callbacks, utility functions, and a data ready function. The callbacks include a parse_msg function that is called to perform parsing (e.g. BPF parsing in case of KCM), and a rcv_msg function that is called when a full message has been completed. For strparser we specify the return codes from the parser to allow the backend to indicate that control of the socket should be transferred back to userspace to handle some exceptions in the stream: The return values are: >0 : indicates length of successfully parsed message 0 : indicates more data must be received to parse the message -ESTRPIPE : current message should not be processed by the kernel, return control of the socket to userspace which can proceed to read the messages itself other < 0 : Error is parsing, give control back to userspace assuming that synchronization is lost and the stream is unrecoverable (application expected to close TCP socket) There is one issue I haven't been able to fully resolve. If parse_msg returns ESTRPIPE (wants control back to userspace) the parser may already have consumed some bytes of the message. There is no way to put bytes back into the TCP receive queue and tcp_read_sock does not allow an easy way to peek messages. In lieu of a better solution, we return ENODATA on the socket to indicate that the data stream is unrecoverable (application needs to close socket). This condition should only happen if an application layer message header is split across two skbuffs and parsing just the first skbuff wasn't sufficient to determine the that transfer to userspace is needed. This patch set contains: - strparser implementation - changes to kcm to use strparser - strparser.txt documentation v2: - Add copyright notice to C files - Remove GPL module license from strparser.c - Add report of rxpause v3: - Restore GPL module license - Use EXPORT_SYMBOL_GPL v4: - Removed unused function, changed another to be static as suggested by davem - Rewoked data_ready to be called from upper layer, no longer requires taking over socket data_ready callback as suggested by Lance Chao Tested: - Ran a KCM thrash test for 24 hours. No behavioral or performance differences observed. ==================== Signed-off-by:
