Newest devices have a new firmware load mechanism. This mechanism is called the context info. It means that the driver doesn't need to load the sections of the firmware. The driver rather prepares a place in DRAM, with pointers to the relevant sections of the firmware, and the firmware loads itself. At the end of the process, the firmware sends the ALIVE interrupt. This is different from the previous scheme in which the driver expected the FH_TX interrupt after each section being transferred over the DMA. In order to support this new flow, we enabled all the interrupts. This broke the assumption that we have in the code that the RF-Kill interrupt can't interrupt the firmware load flow. Change the context info flow to enable only the ALIVE interrupt, and re-enable all the other interrupts only after the firmware is alive. Then, we won't see the RF-Kill interrupt until then. Getting the RF-Kill interrupt while loading the firmware made us kill the firmware while it is loading and we ended up dumping garbage instead of the firmware state. Re-enable the ALIVE | RX interrupts from the ISR when we get the ALIVE interrupt to be able to get the RX interrupt that comes immediately afterwards for the ALIVE notification. This is needed for non MSI-X only. Cc: stable@vger.kernel.org Signed-off-by:

We added code to restock the buffer upon ALIVE interrupt when MSI-X is disabled. This was added as part of the context info code. This code was added only if the ISR debug level is set which is very unlikely to be related. Move this code to run even when the ISR debug level is not set. Note that gen2 devices work with MSI-X in most cases so that this path is seldom used. Cc: stable@vger.kernel.org Signed-off-by:

In AP (and IBSS) mode, we can only set GTKs to firmware after we have sent down the multicast station, but this we can only do after we've enabled beaconing, etc. However, during rfkill exit, hostapd will configure the keys before starting the AP, and cfg80211/mac80211 accept it happily. On earlier devices, this didn't bother us as GTK TX wasn't really handled in firmware, we just put the key material into the TX cmd and thus it only mattered when we actually transmitted a frame. On newer devices, however, the firmware needs to track all of this and that doesn't work if we add the key before the (multicast) sta it belongs to. To fix this, keep a list of keys to add during AP enable, and call the function there. Cc: stable@vger.kernel.org Signed-off-by:

The 0xF6 command used to start and stop the recording from 22560 devices was removed. This is causing an assert when the driver tries to alter the recording state. Remove the use of the command. Signed-off-by:

There are several flows where the driver checks if it runs in ini mode. Some of these flows are no longer used in ini mode or there is another condition that check the ini mode in the same flow. Either way, those conditions are redundant. Remove the redundant conditions. Signed-off-by:

The driver should delay only in recording stop flow between writing to DBGC_IN_SAMPLE register and DBGC_OUT_CTRL register. Any other delay is not needed. Change the following: 1. Remove any unnecessary delays in the flow 2. Increase the delay in the stop recording flow since 100 micro is not enough 3. Use usleep_range instead of delay since the driver is allowed to sleep in this flow. Signed-off-by:

Currently we dump only the first 64 bytes of the PCI config space, which leaves out some important things, such as the base address registers. Increase it to 352 for the PCI device and to 524 for the rootport to make sure we include everything we need. Signed-off-by: -

In some buggy scenarios we could possible attempt to transmit frames larger than maximum MSDU size. Since our devices don't know how to handle this, it may result in asserts, hangs etc. This can happen, for example, when we receive a large multicast frame and try to transmit it back to the air in AP mode. Since in a legal scenario this should never happen, drop such frames and warn about it. Signed-off-by:

South Korea is adding a more strict SAR limit called "Limb SAR". Currently, WGDS SAR offset group 3 is not used (not mapped to any country). In order to be able to comply with South Korea new restriction: - OEM will use WGDS SAR offset group 3 to South Korea limitation. - OEM will change WGDS revision to 1 (currently latest revision is 0) to notify that Korea Limb SAR applied. - Driver will read the WGDS table and pass the values to FW (as usual) - Driver will pass to FW an indication that Korea Limb SAR is applied in case table revision is 1.

The indexes into the ac array in the iwl_mac_ctx_cmd are from the iwl_ac enum and not the txfs. The current code therefore puts the edca params in the wrong indexes of the array, causing wrong priority for data-streams of different ACs. Fix this. Note that this bug only occurs in NICs that use the new tx api, since in the old tx api the txf number is equal to the corresponding ac in the iwl_ac enum. Signed-off-by:

These pointers are an offset into the "sta" struct. They're assigned like this: const struct ieee80211_sta_vht_cap *vht_cap = &sta->vht_cap; They're not the first member of the struct (->supp_rates[] is first) so they can't be NULL. Signed-off-by:

Make use of the struct_size() helper instead of an open-coded version in order to avoid any potential type mistakes, in particular in the context in which this code is being used. So, change the following form: sizeof(*pattern_cmd) + wowlan->n_patterns * sizeof(struct iwlagn_wowlan_pattern) to : struct_size(pattern_cmd, patterns, wowlan->n_patterns) This code was detected with the help of Coccinelle.

When a dump trigger is fired, the driver sets IWL_FWRT_STATUS_DUMPING and aborts any consecutive dump collection. To allow consecutive triggers firing, use 5 dump workers and allocate them upon incoming dump collection requests. This functionality is needed since in ini debug mode each trigger may have entirely different memory regions to collect unlike the legacy mode in which all the triggers dump the same memory regions.

Support more regulatory domains including IC, KCC, ACMA, CHILE, UKRAINE, and MEXICO. Corresponding tx power limits for these regulatory domains are added in tx power limit table. Besides, tx power limits in some case are also updated to follow RF v20 for better tx power indexes. Channel plan mapping table are upgraded to consider more 2G and 5G channel plans combination cases. It allow us to identify different situations more accuratly by channel plan IDs. In addition, mapping table for country code and channel plan ID and mapping table for country code and tx power limit are also updated to follow RF v20. It allow the new enrties in tx power limit table to be applied correctly. Signed-off-by:
