Wireless Broadcom chips can have either their SPROM data stored on either external SPROM or on-chip OTP memory. Both are accessed through the same register space. This patch adds support for the on-chip OTP memory. Tested with: BCM43224 OTP and SPROM BCM4331 SPROM BCM4313 OTP This patch is in response to linux-wireless thread [1].

When not SPROM is available a fallback mechanism is used. However, when that fails the code currently continues. This patch assures that the bcma_sprom_get() function aborts when that happens. Cc: Rafal Milecki <zajec5@gmail.com> Cc: Hauke Mehrtens <hauke@hauke-m.de> Signed-off-by:

All other Atheros drivers run the AGC gain calibration and DC offset calibration only after reset. Running them periodically has caused stability issues on some (primarily AR2315/2413/5413/5414 based) devices, leading to messages such as: ath5k phy0: gain calibration timeout (2462MHz) ath5k phy0: calibration of channel 11 failed Related bug reports: https://dev.openwrt.org/ticket/10574 https://bugzilla.redhat.com/show_bug.cgi?id=795141Signed-off-by:

Some calibration types interfere with tx activity, but the queue stop does not prevent that. In fact, some calibration types need tx activity to properly function, so stopping the queues for them is counterproductive. In some tests this patch has been shown to improve stability, especially in AP or ad-hoc mode. Signed-off-by:

Airtime link metric estimation was broken in HT mesh, use cfg80211_calculate_bitrate to get the right rate value. Also factor out tx rate copying from sta_set_sinfo(). Signed-off-by:

My patch "iwlwifi: simplify auth/assoc flow" caused a serious throughput degradation due to me forgetting that there are HT settings in the station table. To restore throughput, set these parameters correctly when the sta moves to assoc state. This patch should probably be merged with the auth/assoc redesign patch for upstream. In that case, this paragraph should be added to the commit log as the third paragraph (before talking about RXON): However, as we only get the station HT data when the station moves into assoc state, we also need to program this into the device (and copy it into our database) then.

Currently, queue mapping is handled in the transport. This may change, but until then the code for it can be close to where it's used rather than in iwl-shared.h. Signed-off-by:

This is how the transport passes things up into higher layers, so it belongs to the transport API. Signed-off-by:

struct iwl_rx_mem_buffer implementation details (DMA address, list pointers) that the upper layers don't need. Introduce iwl_rx_cmd_buffer that is passed upstream and only contains the needed data (the page). Additionally, access this data only via accessor functions, allowing us to change the implementation in the future. These accessors are rxb_addr() (as before) and rxb_steal_page() to take ownership of the data. Signed-off-by:

When CMD_WANT_SKB is set for a (synchronous) command, the response is passed back to the caller which is then responsible for freeing it. Make this more abstract with real API, passing directly the response packet in the new cmd.resp_pkt member and also introduce iwl_free_resp() to free the pages -- this way the upper layers don't have to directly touch the page implementation. NOTE: This breaks IDI -- the new code isn't reflected there yet! Signed-off-by:

We currently use the _irqsafe version, but that isn't recommended together with ieee80211_rx() as it can cause races. If the device reports a TX-status and RX in that order then with the current combination mac80211 might process them in the other order, which can cause issues with powersaving clients. Use ieee80211_tx_status() to avoid this race. Since we don't want to call it with locks held, process the frame queues later -- this is fine as they are on the stack. Signed-off-by:

With the new WoWLAN flow into the transport there no longer is a need for this to be shared, so move it into priv. Signed-off-by:
-
Johannes Berg authored
In the WoWLAN suspend flow, instead of accessing registers directly, ask the transport to do the required setup at the end of suspend. If the transport doesn't implement this, don't tell the stack we support WoWLAN. When the device suspends w/o WoWLAN, mac80211 will have stopped it already, which has already called iwl_apm_stop() via stop_hw(). Thus, it isn't necessary to call it again in pcie_suspend and we can simply do nothing there. This unifies the regular and WoWLAN suspend. Signed-off-by:

Writing to the global config structures is always wrong. To protect against such mistakes in the future, mark them const. Signed-off-by:

Johannes Berg authored
It's not really a good idea to write to the global static configuration. Use the valid TX/RX antenna information only from the HW params struct except in the case where the values from the config are used to override the values from the EEPROM. Signed-off-by:
-
Johannes Berg authored
There's no SKU override, we always just use it from EEPROM. As such, we can remove it from the config and use it in hw_param only. Since iwl_eeprom_check_sku() really needs to fill it in also rename that to iwl_eeprom_init_hw_params(). Signed-off-by:

There's no need for the per-device debug level that we expose in debugfs since the module parameter is writable in sysfs. At the same time, simplify code by changing iwl_get_debug_level(shrd) & IWL_DL_ISR) to iwl_have_debug_level(IWL_DL_ISR) Signed-off-by: -

With mac80211 now giving us station information (via the sta_state callback) before auth/assoc we can get rid of tx_sync by adding the station early for the case of managed interfaces. Keep AP mode actions the same for now. As we now get the BSSID early, we can also get rid of iwl_reprogram_ap_sta(). We can still optimise the number of RXONs we send to the device, but that can be done later. Signed-off-by:

Johannes Berg authored
There's no reason to set EXIT_PENDING when we start removing the module, as mac80211 will cleanly shut down the device in this case. Additionally, there's no point in rejecting commands to the device when we're cleaning up as that only leads to unwanted errors from mac80211 being printed, such as failed to remove key (...) from hardware (-16) Signed-off-by:
