Hi Kalle,
I did see the patch and noticed the procedural issues as well. However,
last week was a short week over here and I did not get to it to respond.
The fix is not done properly. The function determines the RSSI from the
per-chain values. I suspect that Jaap Jan is using a device which does
not report per-chain values so his solution should be used as fallback.
So can you revert the patch so Jaap Jan can rework the patch, ie.:
if (count_rssi) {
:
} else if (test_bit(BRCMF_VIF_STATUS_CONNECTED,
&ifp->vif->sme_state)) {
memset(&scb_val, 0, sizeof(scb_val));
err = brcmf_fil_cmd_data_get(ifp, BRCMF_C_GET_RSSI,
&scb_val, sizeof(scb_val));
if (err) {
brcmf_err("Could not get rssi (%d)\n", err);
goto done;
} else {
rssi = le32_to_cpu(scb_val.val);
sinfo->filled |= BIT(NL80211_STA_INFO_SIGNAL);
sinfo->signal = rssi;
brcmf_dbg(CONN, "RSSI %d dBm\n", rssi);
}
}
Let me know if that is ok or should I submit a fixup patch.
Regards,
Arend
