This matches how things are done is ath6kl, however, this patch can theoretically handle several bundles in ath10k_sdio_mbox_rx_process_packets(). Without this patch we get lots of errors about invalid endpoint id: ath10k_sdio mmc2:0001:1: invalid endpoint in look-ahead: 224 ath10k_sdio mmc2:0001:1: failed to get pending recv messages: -12 ath10k_sdio mmc2:0001:1: failed to process pending SDIO interrupts: -12 Co-Developed-by: Niklas Cassel Signed-off-by: Alagu Sankar Signed-off-by: Niklas Cassel Signed-off-by: Kalle Valo --- diff --git a/drivers/net/wireless/ath/ath10k/sdio.c b/drivers/net/wireless/ath/ath10k/sdio.c index 926e4c3ea256..4c018a9f3755 100644 --- a/drivers/net/wireless/ath/ath10k/sdio.c +++ b/drivers/net/wireless/ath/ath10k/sdio.c @@ -435,12 +435,14 @@ static int ath10k_sdio_mbox_rx_process_packets(struct ath10k *ar, enum ath10k_htc_ep_id id; int ret, i, *n_lookahead_local; u32 *lookaheads_local; + int lookahead_idx = 0; for (i = 0; i < ar_sdio->n_rx_pkts; i++) { lookaheads_local = lookaheads; n_lookahead_local = n_lookahead; - id = ((struct ath10k_htc_hdr *)&lookaheads[i])->eid; + id = ((struct ath10k_htc_hdr *) + &lookaheads[lookahead_idx++])->eid; if (id >= ATH10K_HTC_EP_COUNT) { ath10k_warn(ar, "invalid endpoint in look-ahead: %d\n", @@ -463,6 +465,7 @@ static int ath10k_sdio_mbox_rx_process_packets(struct ath10k *ar, /* Only read lookahead's from RX trailers * for the last packet in a bundle. */ + lookahead_idx--; lookaheads_local = NULL; n_lookahead_local = NULL; }
