During (TDMA-based) MCC (multi-channel concurrency), the below two cases might not have a good behavior on channel usage. * ROC (remain on channel) * HW scan So, we tend to separate them from MCC. The two cases would expect to operate the channel to which they want. However, during MCC, channels are scheduled by FW MCC state mechanism. So, channels cannot be controlled explicitly. To avoid the two cases from operating wrong channels with chance, we pause MCC (essentially stop FW MCC) once the two cases are coming. And then, we proceed MCC again (essentially restart FW MCC) once the two cases finish.

2023-09-28wifi: rtw89: mcc: fix NoA start time when GO is auxiliaryZong-Zhe Yang
Under TDMA-based MCC (multi-channel concurrency), there are two roles, reference and auxiliary. We arrange MCC timeline based on time domain of reference role. Then, we calculate NoA start time according to MCC timeline. Besides, when MCC runs GO+STA mode, we plan an offset between GO time domain and STA time domain to make their TBTTs have a time gap. However, if GO is auxiliary role instead of reference role, NoA start time is described by STA time domain instead of GO time domain. To fix this, we apply the offset mentioned above to NoA start time to convert time domain from STA to GO.

2023-09-22wifi: rtw89: load TX power related tables from FW elementsZong-Zhe Yang
The following FW elements are recognized, and then the valid entries in them are loaded into SW struct case by case. * TX power by rate * TX power limit 2 GHz * TX power limit 5 GHz * TX power limit 6 GHz * TX power limit RU 2 GHz * TX power limit RU 5 GHz * TX power limit RU 6 GHz * TX shape limit * TX shape limit RU One single firmware file can contain multiples of each of the above FW elements. Each of them is configured with a target RFE (RF front end) type. We choose one of the multiples to load based on RFE type. If there are multiples of the same FW elements with the same target RFE type. The last one will be applied. We don't want to have many loading variants for above FW elements. Even if between different chips or between different generations, we would like to maintain only one single set of loadings. So, the loadings are designed to consider compatibility. The main concepts are listed below. * The driver structures, which are used to cast binary entry from FW, cannot insert new members in the middle. If there are something new, they should always be appended at the tail. * Each binary entry from FW uses a dictionary way containing a key set and a data. The keys in the key set indicate where to put the data. * If size of driver struct and size of binary entry do not match when loading, it means the number of keys in the key set are different. Then, we deal with compatibility. No matter which one has more keys, we take/use zero on those mismatched keys. If driver struct is bigger (backward compatibility): e.g. SW uses two keys, but FW is built with one key. Then, put the data of FW(keyX) into SW[keyX][0]. If binary entry is bigger (forward compatibility): e.g. FW is built with two keys, but SW uses one key. Then, only take the data of FW(keyX, keyY = 0) into SW[keyX] Besides, chip info setup flow is tweaked a bit for the following. * Before loading FW elements, we need to determine chip RFE via efuse. * Setting up RFE parameters depends on loading FW elements ahead.

The subband index is a hardware value of relationship between primary channel and bandwidth, and it is used by setting channel/bandwidth to specify the primary channel.

2023-09-18wifi: rtw89: mcc: deal with beacon NoA if GO existsZong-Zhe Yang
In MCC STA+GO mode, we calculate NoA information and fill it into the beacon of P2P GO. Since NoA uses only 32 bits to describe time things, we need to deal with renewal when TSF[63:32] is carried. We trigger FW to notify that. Then, we can update NoA information for new time period once we get notification from FW.

In MCC STA+GC mode, the offset between TBTTs of remote AP and remote GO might change. If the change is larger than tolerance, we should update MCC after re-calculating parameters for new things. So, we track that in rtw89_track_work() now. And, we add MCC update flow to tell FW either to change durations of roles or to replace entire pattern according to how MCC plans BT slot.

2023-09-18wifi: rtw89: mcc: update role bitmap when changedZong-Zhe Yang
Each MCC (multi-channel concurrency) role maintains a bitmap of mac IDs. The bitmap is supposed to contain the two points below. * mac ID of itself * mac ID(s) of STA(s) connecting to it Under STA+GC mode, the bitmaps of both roles should not change. However, under STA+GO mode, the bitmap of GO may change due to P2P clients which connect/disconnect to/from it. FW controls (TDMA-based) MCC things via mac IDs in bitmap of each role. For example, mac IDs are required by FW when it wants to pause role1's TX in role0 slot. So, to sync between driver and FW, we update the new mac ID bitmap of GO to FW once it's changed.

DPK is one kind of RF calibration. When MCC (multi-channel concurrency) start/stop, DPK needs to do extra things to be off/on.

2023-09-18wifi: rtw89: rfk: disable driver tracking during MCCZong-Zhe Yang
After MCC (multi-channel concurrency) is started, FW will control channel changes and use the corresponding backup of RF calibration result. And, driver RF calibration (RF-K) won't be able to keep up with the speed at which the channels are changing. So, even if we keep tracking it in driver, the RF-K result might not be good either. To save these unnecessary things, we disable driver RF-K tracking during MCC.

RF calibration will notify FW to backup the calibration result after it is done on a channel. For MCC (multi-channel concurrency) flow, when we at RTW89_ENTITY_MODE_MCC_PREPARE mode, RF calibration should execute on second channel of MCC, i.e. RTW89_SUB_ENTITY_1, and then, notify FW to backup the result for the second one. Originally, the RF calibration flow only fit single channel case. We are planning to support MCC on RTL8852C, so we refine its RF calibration flow to fit MCC case.
