2025-04-28wifi: rtw89: refactor flow that hw scan handles channel listZong-Zhe Yang
FW has a limited amount of channels that can be dealt with by one HW scan H2C command. Based on the limit, channels in scan request might be parsed into SW structure piece by piece along with multiple HW scan H2C commands. But, in order to estimate things of entire HW scan process, it's required to have the whole parsed channel list when HW scan is going to start. So, tweak HW scan flow to prepare the whole channel list ahead. Still, each HW scan H2C command takes allowed amount of channels from the list according to the limit.

2025-02-10wifi: rtw89: call power_on ahead before selecting firmwarePing-Ke Shih
Driver selects firmware by hardware version, which normally can be read from registers before selecting firmware. However, certain chips such as RTL8851B, it needs to read hardware version from efuse while doing power_on, but do power_on after selecting firmware in current flow. To resolve this flow problem, move power_on out from rtw89_mac_partial_init(), and call rtw89_mac_pwr_on() separately at proper places to have expected flow.

2024-11-27wifi: rtw89: 8922a: configure AP_LINK_PS if FW supportsZong-Zhe Yang
After FW v0.35.46.0, for AP mode, RTL8922A FW supports a new FW feature, called NOTIFY_AP_INFO, to notify driver information related to AP mode. And, one function of it is to monitor PS states of remote stations. Once one of them changes, FW will send a C2H event to tell driver. With this FW feature, we can declare AP_LINK_PS. For now, driver still needs to determine if a frame is ps-poll or U-APSD trigger. So, add the corresponding RX handling in driver, which activates only when at least one AP is running.

2024-10-25wifi: rtw89: add thermal protectionPing-Ke Shih
To prevent chip overheating, reduce TX duty as the mechanism of thermal protection. When temperature is raising over a threshold, send a firmware command to reduce TX duty. If temperature is still raising, higher level is adopted to have lower active duration. The equation and unit of thermal values are different from chip to chip, so define constant thresholds of thermal value to corresponding absolute temperature of 110 and 120 degree Celsius. Latter patch will decide which thermal threshold is adopted, and current is still not enable thermal protection. For debugging, add a flag to disable_dm that thermal protection can be disabled to clarify low throughput in field.

For cases of non-MLD connection, we set our link instance-0 active with link_id 0. So, our code flow can be compatible between non-MLD connection and MLD connection. Based on above, we tweak entire driver architecture first. But, we don't dynamically enable multiple links here. That will be handled separately. Most of the things changed here are changing flows to iterate all active links and read bss_conf/link_sta data according to target link. And, for cases of scan, ROC, WOW, we use instance-0 to deal with the request. There are some things listed below, which work for now but need to extend before multiple active links. 1. tx path select suitable link instance among multiple active links 2. rx path determine rx link by PPDU instead of always link instance-0 3. CAM apply MLD pairwise key to any active links dynamically Besides, PS code cannot easily work along with tweaking architecture. With supporting MLO flag (currently false), we disable PS first and will fix it by another commit in the following.

When STA connects to an AP and doesn't receive any beacon yet, the hardware scan is triggered. This scan begins with the default TSF value. Once STA receives a beacon when switches back to the operating channel, its TSF synchronizes with the AP. However, if there is a significant difference in TSF values between the default value and the synchronized value, it will cause firmware fail to trigger interrupt, and the C2H won't be sent out. As a result, the scan continues until a timeout occurs. To fix this issue, we disable TSF synchronization during scanning to prevent drastic TSF changes, and enable TSF synchronization after scan.

The power on/off functions are to turn on hardware function blocks and to turn off them if we are going to stay in idle state. Signed-off-by: Ping-Ke Shih <pkshih@realtek.com> Signed-off-by: Kalle Valo <kvalo@kernel.org> Link: https://msgid.link/20231211083341.118047-3-pkshih@realtek.com
2023-12-15wifi: rtw89: add XTAL SI for WiFi 7 chipsPing-Ke Shih
The XTAL SI is a serial interface to indirectly access registers of analog hardware circuit. Since WiFi 7 chips use different registers, add a ops to access them via common functions. This patch doesn't change logic for existing chips.

2023-12-07wifi: rtw89: 8922a: dump MAC registers when SER occursChia-Yuan Li
To diagnose the reason why firmware or hardware get abnormal, add to dump MAC registers related to counters and interrupt masks. With these values, people can classify problems and check if registers values are unexpected, and then correct them. However, it could possible false alarm because firmware triggers this SER event by wrong conditions that we should correct it at firmware or register settings. In field, SER might happen under special conditions, and very hard to happen again, so dump lots of registers to provide rich information to catch the problem.

2023-12-01wifi: rtw89: fix misbehavior of TX beacon in concurrent modeChih-Kang Chang
In concurrent mode, when STA interface is scanning, it causes AP interface TX beacon on wrong channel. We modified it to scan with the operating channel when one of the interfaces is already connected. Additionally, STA interface need to stop scan when AP interface is starting to avoid TX beacon on wrong channel. Finally, AP interface need to stop TX beacon when STA interface is scanning and switching to non-OP channel,This prevent other device to get beacons on wrong channel.

2023-12-01wifi: rtw89: mac: check queue empty according to chip genZong-Zhe Yang
This function, currently called by WoWLAN flow, polls until specific HW queues are empty. The polling bit definitions are not totally the same between WiFi 6 and 7 chips. In addition, the check conditions are also a little different. So, we differentiate the implementations according to chip gen.
