| | * wil6210: prevent external wmi commands during suspend flowMaya Erez2015-12-082-1/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In __wmi_send we check if fw is ready at the beginning of the function. While we wait for the completion of the previous command, system suspend can be invoked and reset the HW, causing __wmi_send to read from HW registers while it is not ready. Taking the wmi_mutex in the reset flow when setting the FW ready bit to zero will prevent the above race condition.

| | | | | | | | | | | | | | | Allow network stack part of Rx processing to run on separate core, relaxing CPU utilization on the core used for Rx NAPI. If RXHASH feature is enabled, the driver sets rxhash of each skb to 1 to enable RPS. The core for processing the rx skb is determined by RPS mechanism according to rx_cpus bit mask which is configured at user level. For processing skbs on different core from the core which processes the interrupts, it is recommended not to enable core 0 in rx_cpus bit mask.

In data path skbs are checked for non-zero gso_size, and when detected sent to additional function for processing TSO SKBs. Since HW does not fully support TSO, additional effort is required from the driver. Driver partitions the data into mss sized descriptors which are then DMAed to the HW.

In the future git could get Coccinelle merge support to deal with patch --> fail --> grammar --> Coccinelle --> new patch conflicts automatically for us on patches where the grammar is available and the patch is of high confidence.
