-11 is -EAGAIN which would mean that the HTC credits have run out some reason for the WMI command: if (ep->tx_credits < credits) { ath10k_dbg(ar, ATH10K_DBG_HTC, "htc insufficient credits ep %d required %d available %d\n", eid, credits, ep->tx_credits); spin_unlock_bh(&htc->tx_lock); ret = -EAGAIN; goto err_pull; } Credits can run out, for example, if there's a lot of WMI command/event activity and are not returned during the 3s wait, firmware crashed or problems with the PCI bus.Hi Can this occur if the target memory is not properly allocated?
I have only seen this on wave-1 cards, and it is usually paired with situations where the wave-1 stops doing WMI related interrupts properly as best as I can understand. If I force the firmware to poll instead of waiting for irqs, then WMI communication will work for a while...I have not implemented that on the driver side though, so I still see these WMI timeout issues.
