2023-08-25wifi: rtw89: phy: modify register setting of ENV_MNTR, PHYSTS and DIGCheng-Chieh Hsieh
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.

2023-08-25wifi: rtw89: phy: add phy_gen_def::cr_base to support WiFi 7 chipsPing-Ke Shih
cr_base is base address of PHY control register. 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. The offset between them is 0x2_0000, so the base address of PHY0 and PHY1 are 0x2_0000 and 0x4_0000 respectively.

address There are two copies of MAC hardware called band0 and band1. Basically, the only difference between them is base address, so we can share functions with a 'band' (or 'mac_idx') argument. The offset of base address of WiFi 6 and 7 are 0x2000 and 0x4000 respectively, so add band1_offset field to new introduced struct mac_gen_def to possibly reuse functions.

2023-08-03wifi: rtw89: return failure if needed firmware elements are not recognizedPing-Ke Shih
WiFi 7 chips doesn't have static const tables defined in driver. 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. Currently, the needed firmware elements of WiFi 6 chips are all zero, and coming WiFi 7 chip will need at least BB MCU, parameters of BB and RF. We will add them after 8922AE is verified.

2023-04-14wifi: rtw89: support parameter tables by RFE typeZong-Zhe Yang
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.

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

GNT_BT WiFi/BT combo module could only have two antenna, namely WL_S0 and WL_S1. WiFi can use two antenna to TX/RX 2SS data, and BT can share one of the antenna. This patch is to allow WiFi to TX/RX 1SS data like ACK/RTS/CTS to improve Wi-Fi performance while coexisting with Bluetooth.

Sometimes, BB might encounter RX problem on OFDM 6M. It's not quite easy to happen, but if it happens, we will keep getting stuck on RX. And, since we cannot properly receive layer 2 ACK, it also casues TX problem, e.g. constantly retrying TX. Eventually, after some time, we would get disconnected due to abnormal behavior. Update break setting and phy status parsing time to make BB get out of stuck state faster.

2022-09-02wifi: rtw89: early recognize FW feature to decide if chanctxZong-Zhe Yang
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.
