If we are in d0i3 when entering suspend, we leave d0i3 so that mac80211 can call us to remove connections or whatever before going to suspend. We do this by calling pm_runtime_resume() early in the slave transport flow and reactivating it later, when the wiphy suspend flow runs. The problem is that we queue a work in order to leave d0i3. If this work hasn't run yet when the wiphy suspend flow is called, we have a race and entering d0i3 fails (because we're still holding the IWL_MVM_REF_EXIT_WORK reference). To solve this, simply flush the d0i3_exit_work at the beginning of the iwl_mvm_suspend() function. Signed-off-by: NLuciano Coelho <luciano.coelho@intel.com>

When in AP mode, we need beacons from other APs for HT protection. However, when there's no any associated station we will not do any Tx and thus don't really need beacons. On the other hand, these beacons will cause a lot of unnecessary wakeups which increase our power consumption. Handle this by asking FW to pass beacons only when there's at least one associated station.

When receiving statistics notification there is a field of average energy. This is defines as signed 8 bit, while FW refers to it as unsigned. when the energy is higher than 127 this causes in iwl_mvm_stat_iterator a wrong computation of the signal int sig = -stats->general.beacon_filter_average_energy; resulting in incorrect CQM event (change from low to high).

This debugfs entry was implemented just as a proof-of-concept before the full support for netdetect via cfg80211/mac80211 was implemented. Now that we have a proper way to enable netdetect from userspace, this entry is redundant and should be removed to avoid unnecessary maintenance work.

My static checker complains that we don't check for underflows in iwl_dbgfs_fw_dbg_conf_write().

When we enter D0i3, we must stop TXing otherwise the sequence number we use might conflict with the firmware's internal TX. In order to do so, we have IWL_MVM_STATUS_IN_D0I3 which should prevent any Tx while we enter D0i3. There is a bug in this code since we may Tx even if IWL_MVM_STATUS_IN_D0I3 is set. This can happen as long as mvm->d0i3_ap_sta_id is not set. To make sure that we don't have any packet in the Tx path while we set mvm->d0i3_ap_sta_id, call synchronize_net only after we already set mvm->d0i3_ap_sta_id.

Currently if we wake up during D0I3 due to beacon loss we disconnect immediately. This behaviour causes redundant disconnection, which could be prevented by polling as it is usually done in mac80211. Instead, we prefer reporting beacon loss and let mac80211 try polling before disconnection.

There is no need to use hex_dump_to_buffer() in the cases like this: hexdump_to_buffer(buf, len, 16, 1, outbuf, outlen, false); /* len <= 16 */ sprintf("%s\n", outbuf); since it maybe easily converted to simple: sprintf("%*ph\n", len, buf); Note: it seems in one case the output is groupped by 2 bytes and looks like a typo.

The mac80211 patch to pass the NAPI struct only changed iwlwifi to store the NAPI struct, but we can do better: pass it directly from the lower transport layer to the opmode during RX, and then on to mac80211 from there.

Instead of using the out-of-line average calculation, use the new DECLARE_EWMA() macro to declare a signal EWMA, and use that. This actually *reduces* the code size slightly (on x86-64) while also reducing the station info size by 80 bytes. Signed-off-by: NJohannes Berg <johannes.berg@intel.com>

由 Johannes Berg 提交于
Having the EWMA parameters stored in the runtime struct imposes memory requirements for the constant values that could just be inlined in the code. This particularly makes sense if there are a lot of such structs, for example in mac80211 in the station table where each station has a number of these in an array, and there can be many stations. Provide a macro DECLARE_EWMA() that declares the necessary struct and inline functions to access it with the parameters hard-coded; using this also means the user no longer needs to 'select AVERAGE' as it's entirely self-contained. In the mac80211 case, on x86-64, this actually slightly *reduces* code size, while also saving 80 bytes of runtime memory per sta. Signed-off-by: NJohannes Berg <johannes.berg@intel.com>
