Therefore, the threshold is dynamically adjusted to make EDCCA suitable for any situation. However, in some cases, we will adjust the EDCCA threshold to the highest level so that urgent transmissions can be performed successfully, such as scanning. Finally, in order to observe the EDCCA report in time, add the EDCCA perIC register macro and EDCCA HW report analysis. EDCCA logs can be displayed by using the EDCCA debug mask.

wifi: rtw89: mac: add to access efuse for WiFi 7 chips MAC address, hardware type, calibration values and etc are stored in efuse, so we read them at probe stage and use them as capabilities to register hardware. There are two physical efuse -- one is the main efuse for digital hardware part, and the other is for analog part. Because they are very similar, we only describe the main efuse below. The main efuse is split into two regions -- one is for logic map, and the other is for physical map. For both regions, we use the same method to read data, but need additional parser to get logic map. To allow reading operation, we need to convert power state to active, and turn to idle state after reading. For WiFi 7 chips, we introduce efuse blocks to define feature group easier, and these blocks are discontinue. For example, RF block is from 0x1_0000 ~ 0x1_0240, and the next block PCIE_SDIO is starting from 0x2_0000. Comparing to old one used by WiFi 6 chips, there is only single one logic map, it would be a little hard to add an new field to a group if we don't reserve a room in advance. The relationship between efuse, region and block is shown as below: (logical map) +------------+ +---------------+ +-----------------+ | main efuse | | region 1 | | block 0x1_0000~ | | (digital) | |(to logcal map)| +-----------------+ | | | | => +-----------------+ | | => | | | block 0x2_0000~ | | | | | +-----------------+ | | |---------------| : | | | region 2 | +------------+ +---------------+ +------------+ +-----------------+ | 2nd efuse | ======================> | block 0x7_0000~ | | (analog) | +-----------------+ +------------+ The parser converting from raw data to logic map is to decode block page, block page offset, and word_en bits. Each word_en bit indicates two following bytes as data of logic map, so total four word_en bits can represent eight bytes. Thus, block page offset is 8-byte alignment. The layout of a tuple is shown as below +--------+--------+--------+--------+--------+--------+ | fixed 3 byte header | | | | | | | | | | [19:17] block_page | | | ... | | [16:4] block_page_offset| | | | | [3:0] word_en | ^ | ^ | | +----|---+--------+--------+---|----+----|---+--------+ | | | +-------------------------+---------+ a word_en bit indicates two bytes as data For example, block_page = 0x3 block_page_offset = 0x80 (must 8-byte alignment) word_en = 0x6 (b'0110; 0 means data is presented) following 4 bytes = 34 56 78 90 Then, 0x3_0080 = 34 56 0x3_0086 = 78 90 A special block page is RTW89_EFUSE_BLOCK_ADIE (7) that uses different but similar format, because its real efuse size is smaller than main efuse.

wifi: rtw89: phy: modify register setting of ENV_MNTR, PHYSTS and DIG The ENV_MNTR(environment monitor) is the dynamic mechanism which based on the HW of CCX(Cisco Compatible Extensions) which provide the channel loading and noisy level indicator to debug or support the 802.11k. The PHYSTS provide the detail PHY information per packet we received for debugging. The DIG(dynamic initial gain) is the dynamic mechanism to adjust the packet detect power level by received signal strength to avoid false detection of the WiFi packet. The address of registers used for ENV_MNTR, PHYSTS and DIG of WiFi 7 IC are different with WiFi 6 series, so we modify the method to access the register address in order to compatible with all WiFi 7 and 6 ICs.

The base of WiFi 6 and 7 chips are 0x1_0000 and 0x2_0000 respectively, so define them accordingly. For example, if PHY address is 0x1330, absolute address is 0x1_1330 for WiFi 6 chips, and 0x2_1330 for WiFi 7 chips. Meanwhile, there are two copies of PHY hardware named PHY0 and PHY1.

If tables aren't loaded properly from firmware file, driver can get NULL pointer access exception. One way is to add the checking statements when trying to access these tables, but I choose to check them right after loading firmware elements from firmware file, so I don't need to add error handlers everywhere.

wifi: rtw89: support parameter tables by RFE type One chip can have different RFE (RF front end) types which we will judge at runtime. And, different RFE types may use different RF parameter tables. Though we didn't really meet this case previously, we are going to meet it on upcoming chip RTL8851B. So, this commit handles parameter tables for runtime RFE type. We now encapsulate rtw89_txpwr_rule_<2/5/6>ghz tables into rtw89_rfe_parms. Then, each chip defines its default parameter tables, and if needed, it can configure extra parameter tables by RFE type. Finally we determine runtime parameter tables by RFE type if one is configured. Otherwise, we use the default parameter tables. For now, we just move all settings under default parameter tables. We will configure parameter tables by RFE types in separate commits afterwards.

wifi: rtw89: add WoWLAN function support WoWLAN is a feature which allows devices to be woken up from suspend state through WLAN events. When user enables WoWLAN feature and then let the device enter suspend state, WoWLAN firmware will be loaded by the driver and periodically monitors WiFi packets. Power consumption of WiFi chip will be reduced in this state. We now implement WoWLAN function in rtw8852ae and rtw8852ce chip. Currently supported WLAN events include receiving magic packet, rekey packet and deauth packet, and disconnecting from AP.

So, setting functions are implemented chip by chip. However, until now, the functions keep the same among chips, at least 8852A, 8852C, and 8852B. There is a sufficient number of chips to share generic setting functions. So, we now remake them including TX power by rate, TX power offset, TX power limit, and TX power limit RU as generic ones in phy.c.

wifi: rtw89: early recognize FW feature to decide if chanctx In current flow, FW is asynchronously loaded after alloc_hw(). It defers the decision on FW feature map. It makes things difficult for us to decide whether to hook chanctx ops, which should be decided while alloc_hw() is calling. Still, asynchronous gets its advantages. So, we want to resolve this without dropping them. Based on multi-FW flag, RTW89_MFW_SIG, we can determine runtime FW is multi-FW (MFW) or single FW (SFW). Both of them have a quite small chunk for header at the head. The difference is that MFW doesn't describe version code in its header while SFW does. So, we plan to extend MFW header for version code. After that, in both cases, we can determine FW feature map by just FW header. And, according to the map, we can decide chanctx. So, we call request_partial_firmware_into_buf() to request a quite small chunk before alloc_hw() to get a early FW feature map without affecting things much and only use early map to decide whether to hook chanctx ops. It means that if non-extended MFW is used at runtime, driver just acts without chanctx as before. If extended MFW or SFW, which supports required FW features, is used at runtime, driver can hook chanctx ops to mac80211 if chip has configured support_chanctx_num > 0. Besides, key point for now to support single one chanctx is whether HW scan is supported at runtime. So, we configure all chip's support_chanctx_num to 1, and check if HW scan is supported at runtime via early FW feature map.

wifi: rtw89: declare support for mac80211 chanctx ops by chip Some HW features are required if we hook chanctx ops to mac80211. With it, mac80211 would expect the HW-supported variant ops exists on some behavior, e.g. HW scan. But, HW features may depend on chip's FW or its development. Besides, how many chanctx can be supported also depends on chip design. We can neither decide whether to generally support chanctx ops nor how many chanctx can be supported. So, support_chanctx_num is added under chip info to deal with this by chip. For now, all chip configure support_chanctx_num as 0. We haven't really hook chanctx ops yet.

We will implement and support chanctx with single channel first, i.e. only use entry in RTW89_SUB_ENTITY_0, before handling dual channels. Our hierarchy in planning will become as the following.

Do this calibration when we are going to run on AP channel.

The ::set_txpwr_ctrl and ::init_txpwr_unit are called when we up interface and then configure TX power registers to initial values. The ::set_txpwr_ctrl is to configure 'txpwr_ref' to make basic output TX power of OFDM and CCK rate to be the same. The ::init_txpwr_unit is to initialize TSSI (a method to do TX power compensation depends on thermal value) control and bandedge. The ::set_txpwr is called once switching channel. First, it sets TX power for each rate section (e.g. CCK, OFDM), and then sets TX power offset between 1SS and 2SS rate. Finally, it sets TX power limit to prevent power over regulation.

rtw89: ps: access TX/RX rings via another registers in low power mode In low power mode, we need to pause PCI to configure IMR and PCI ring index registers accordingly, because the regular registers are power-off in this mode. In the transition moment named paused in code, we can't touch ring index, so don't kick off DMA immediately. Instead, queue them into pending queue, and kick off after the moment. There are three low power modes, which are RF off/clock gate/power gate, but PCI enter low power mode in later two modes only. So, add a mask to achieve this.

rtw89: implement stop and resume channels transmission v1 These function is used to stop transmitting when we are going to switch channels or do some RF calibration. Before these operations, we need to stop channel transmission and backup setting into parameter tx_en. After operations are done, resume transmitting by backup parameter tx_en.
