2024-02-08wifi: cfg80211/mac80211: move puncturing into chandefJohannes Berg1-5/+5
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.

Clang warns (or errors with CONFIG_WERROR=y): drivers/net/wireless/ath/ath12k/mac.c:8060:9: error: variable 'ret' is uninitialized when used here [-Werror,-Wuninitialized] 8060 | return ret; | ^~~ drivers/net/wireless/ath/ath12k/mac.c:8022:9: note: initialize the variable 'ret' to silence this warning 8022 | int ret, i, j; | ^ | = 0 1 error generated. Commit 6db6e70a17f6 ("wifi: ath12k: Introduce the container for mac80211 hw") added a completely uninitialized use of ret. Prior to that change, -ENOMEM was returned to the callers of ath12k_mac_allocate() whenever ath12k_mac_hw_allocate() failed. Assign that value to ret to make sure it is always initialized when used and clear up the warning.

2024-02-07wifi: ath12k: move peer delete after vdev stop of station for WCN7850Kang Yang1-45/+54
In current code, when STA/P2P Client connect to AP/P2P GO, the WMI command sequence is: peer_create->vdev_start->vdev_up And sequence of STA/P2P Client disconnect from AP/P2P GO is: peer_delete->vdev_down->vdev_stop This sequence of disconnect is not opposite of connect. For STA or P2P GO, bss peer is not needed by firmware during handling vdev stop command. So with this sequence, STA and P2P GO can work normally. But for P2P Client, firmware needs bss peer in some functions during handling vdev stop command. The opposite sequence of disconnect should be: vdev_down->vdev_stop->peer_delete So change the sequence of disconnect as above opposite sequence for WCN7850.

2024-02-02wifi: ath12k: fix firmware assert during insmod in memory segment modeAaradhana Sahu1-2/+2
In segment memory mode, firmware allocates memory segments of size 2 MB. This 2 MB memory is used by firmware for the number of peers. This number of peer is sent from host to firmware during WMI init command. For single-phy the number of peers sent is TARGET_NUM_PEERS_SINGLE = 529 (512 + 17). While for split-phy number of peers sent to firmware is TARGET_NUM_PEERS_DBS = 2 *(512 + 17) = 1058. With this 1058 number of peers firmware is unable to allocate memory in 2 MB segment and firmware crash is observed. Hence, fix this firmware crash by reducing the number of stations TARGET_NUM_STATIONS for split-phy.

2024-01-24wifi: ath12k: Fix issues in channel list updateSriram R1-1/+1
Currently, the logic used to select the 6 GHz band is incorrect, which may cause 6 GHz supported channels to not be updated properly. This is because the 6 GHz Max frequency supported by the driver is being compared to the Max frequency supported on the board. If in some cases, the 6 GHz Max frequency supported on the board is less than the defined 6 GHz Max frequency, all 6 GHz channels are disabled. To address this, compare the max frequency supported by the board to the defined 6 GHz Minimum frequency by the driver. Similarly, when a dual mac card supports both 6 GHz and 5 GHz radios, if the 5 GHz radio gets enumerated first before 6 GHz, the checks in ath12k_mac_setup_channels_rates() can cause the 5 GHz channels which were enabled earlier to get disabled when the 6 GHz channel list is updated. This is because the Min 6 GHz frequency defined in the driver is 5945 MHz, which should be 5925 MHz since channel 2 is not considered currently, but the firmware can pass 5925 MHz as the minimum. Hence, update the Min frequency supported by the driver to 5925 MHz. In addition, ensure that the channel list update to firmware updates only the channels that the current radio (ar) supports rather than considering the wiphy support. This would be required when multiple pdevs are supported in a wiphy and they support different ranges of frequencies or bands as in single wiphy support.

2024-01-19wifi: ath12k: Introduce the container for mac80211 hwKarthikeyan Periyasamy1-131/+286
To support multi link operation, we need to combine all the link/pdev under a single wiphy. This avoids the overhead of synchronization across multiple hardware instances in both the cfg80211 and mac80211 layers. Currently, each link/pdev is registered as separate wiphy, tightly coupled with link/pdev/radio (ar) structure. To enable single wiphy registration within the chip, we decouple the wiphy data entity from the link/pdev/radio (ar) structure and move it under the chip (ab) structure with a new data container (ath12k_hw) structure. This approach improves scalability for future multi link operation support. mac80211 hw private data structure diagram ------------------------------------------ Now After +---------------------+ +---------------------+ |mac80211 hw priv data| |mac80211 hw priv data| | | | | | | | | | | | | | | | ath12k_hw (ah) | | | | | | | +-------------------> | | | ath12k (ar) | | +-------------+ | | | | | | | | | | | ath12k (ar) | | | | | | | | | | | | | | | | | +-------------+ | | | | | | | | | +---------------------+ +---------------------+ Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1 Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3 Signed-off-by: Karthikeyan Periyasamy <quic_periyasa@quicinc.com> Signed-off-by: Kalle Valo <quic_kvalo@quicinc.com> Link: https://msgid.link/20240118010320.3918136-3-quic_periyasa@quicinc.com

2023-10-02wifi: ath12k: add keep backward compatibility of PHY mode to avoid firmware ↵Wen Gong1-2/+63
crash In a special WCN7855 firmware release the EHT (IEEE 802.11be) support has been disabled for size reduction. Currently ath12k always enables EHT PHY mode during vdev start but with the special firmware that will cause a firmware crash during vdev start in firmware initialisation. This is because the firmware will use the EHT mode to allocate resources but as the EHT mode is not available in the firmware, there's an internal conflict and the firmware will crash. To fix the crash check the WMI_TLV_SERVICE_11BE flag to see if the firmware supports EHT. If EHT is not supported downgrade the PHY mode to HE (IEEE 802.11ax). This does not impact QCN9274, because WMI_SERVICE_11BE is always enabled for QCN9274, then eht_cap->has_eht will always set for it, and the logic of this patch will not take effect and the PHY mode will not down grade for it.
