2024-06-27wifi: rtw89: add polling for LPS H2C to ensure FW receivedChih-Kang Chang1-0/+7
We add polling after sending LPS H2C to ensure that the Firmware is received and executes RPWM thereafter. Otherwise, if the Firmware executes RPWM without receiving LPS H2C, it will cause beacon loss in WoWLAN mode due to the inability to obtain channel and bandwidth information from H2C.

2024-05-23wifi: rtw89: fix HW scan not aborting properlyPo-Hao Huang1-1/+8
There is a length limit on the commands we send to firmware, so dividing to two commands is sometimes required when scanning. When aborting scan, we should not send second scan command to firmware after the first one is finished. This could cause some unexpected errors when we cannot receive firmware events (e.g. in suspend). Another case is scan happens before suspending, ieee80211_do_stop() is called to abort scan and driver indicate scan completion by ieee80211_scan_completed(), which queues event to scan work. But scan work might be late to execute after ieee80211_do_stop(). To correct this, driver indicates ieee80211_scan_completed() before returning, so that ieee80211_do_stop() can flush scan work properly.

Aloka originally suggested that puncturing should be part of the chandef, so that it's treated correctly. At the time, I disagreed and it ended up not part of the chandef, but I've now realized that this was wrong. Even for clients, the RX, and perhaps more importantly, CCA configuration needs to take puncturing into account. Move puncturing into the chandef, and adjust all the code accordingly. Also add a few tests for puncturing in chandef compatibility checking.

2024-02-06wifi: rtw89: fw: parse secure section from firmware filePing-Ke Shih1-14/+188
A firmware file can contains more than one section with secure type, so use secure information from efuse to choose the one with matched cryptography method. Then choose key data from MSS poll (multiple security section pool; see below picture) according to key_index from efuse. Note that the size of MSS pool isn't included in section size defined in firmware header, so we also need to parse header of MSS pool to get its size as shift to parse next section. If secure boot isn't supported by current hardware, the first secure section will be adopted, and no need additional process to key data. +---------------------------+ | firmware header | | | | +-----------------------+ | | | section type/size * N-|-|-------+ | | ... | | | | +-----------------------+ | | +---------------------------+ | : : | +---------------------------+ -\ | | secure section type (ID:9)| | | | | | <--+ | | | +---------------------------+ -/ |MSS Pool for above section | | | | | +---------------------------+ Signed-off-by: Ping-Ke Shih <pkshih@realtek.com> Signed-off-by: Kalle Valo <kvalo@kernel.org> Link: https://msgid.link/20240204012627.9647-4-pkshih@realtek.com

2024-01-23wifi: rtw89: fix HW scan timeout due to TSF sync issueChih-Kang Chang1-2/+3
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.
