2024-01-23wifi: rtw89: 8922a: add chip_ops related to BB initPing-Ke Shih
The chip_ops::bb_preinit and ::bb_postinit are called before and after loading BB parameters from tables of firmware file. The ::bb_reset is used to reset hardware state, and currently it is not needed by 8922AE so leave it as empty. The ::bb_sethw is to implement conditional parameters.

2024-01-18wifi: rtw89: fw: update TX AMPDU parameter to CMAC tablePing-Ke Shih
The CMAC table is used to define how hardware TX a certain packet, and we can specify TX AMPDU size, so hardware can prepare proper retry window buffer. Otherwise, it can't transmit with expected aggregation number. Since each TID could have different aggregation number, the smallest number is adopted to prevent over peer's receiving buffer.

2023-11-30wifi: rtw89: phy: dynamically adjust EDCCA thresholdYi-Chen Chen
Add dynamic mechanism EDCCA (Energy Detection Clear Channel Assessment) in track work. Using a fixed-value threshold will make EDCCA particularly sensitive and cause failure to transmit under certain circumstances. 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.

2023-11-22wifi: rtw89: mac: add to access efuse for WiFi 7 chipsPing-Ke Shih
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.

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.

2023-04-14wifi: rtw89: add firmware format version to backward compatible with older ↵Ping-Ke Shih
drivers In the discuss threads [1] [2], new firmware format break user space because older drivers can't recognize new firmware format. To avoid this, the new format will be named rtw89/rtw8852b_fw-1.bin and only new driver try to load it. Old drivers only load original and understandable firmware rtw89/rtw8852b_fw.bin. More, new driver will be still backward compatible with old firmware, so original firmware can be used by new driver. If there is newer firmware format is introduced, rtw89/rtw8852b_fw-2.bin will be given. The same rules will be applied like above. So, we will have firmware like below in linux-firmware in the future. rtw89/rtw8852b_fw-2.bin rtw89/rtw8852b_fw-1.bin rtw89/rtw8852b_fw.bin After this patch, MODULE_FIRMWARE() of 8852A/B/C become rtw89/rtw8852a_fw.bin rtw89/rtw8852b_fw-1.bin rtw89/rtw8852c_fw.bin [1] https://lore.kernel.org/linux-wireless/df1ce994-3368-a57e-7078-8bdcccf4a1fd@gmail.com/T/#m24cb43be31a762d0ea70bf07f27ae96c59f6931b [2] https://bugzilla.kernel.org/show_bug.cgi?id=217207 Signed-off-by: Ping-Ke Shih <pkshih@realtek.com> Signed-off-by: Kalle Valo <kvalo@kernel.org> Link: https://lore.kernel.org/r/20230320130606.20777-4-pkshih@realtek.com

The register-based H2C/C2H are used to exchange information between driver and firmware, but only apply to narrow area because its data size is smaller than regular packet-based H2C/C2H. This kind of H2C/C2H must be paired. To identify if any H2C/C2H is missing, update counters to help diagnose this kind of problems.

New firmware type NORMAL_CE is introduced to support P2P-PS and hardware scan, but no LPS-PG mode. After this patch, old firmware with NORMAL type can still work well. The use of this new type is the same as before, so we add new type to avoid taking wrong firmware.

There are some registers for transmit waveform control, two of them used in this change are for BANDEDGE and TX_SHAPE control. BANDEDGE controls whether to apply band edge filter to transmit waveform. TX_SHAPE controls whether to apply triangular mask to transmit waveform.

2022-11-01wifi: rtw89: add WoWLAN pattern match supportChin-Yen Lee
Pattern match is an option of WoWLAN to allow the device to be woken up from suspend mode when receiving packets matched user-designed patterns. The patterns are written into hardware via WoWLAN firmware in suspend flow if users have set up them. If packets matched designed pattern are received, WoWLAN firmware will send an interrupt and then wake up the device.

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.
