Add support for
1. enabling MU-MIMO in HE and EHT modes from hardware
2. setting fixed HE rate/GI/LTF
3. 160 MHz bandwidth in HE mode
4. extended NSS bandwidth support
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
changes in v15:
- rebased the series after merge conflicts reported
patch 4/9:
- change the fix to apply for all modes except STA mode as
WCN7850 expect it same as before.
changes in v14:
patch 6/9:
- cap max_nss using ar->num_tx_chains to fix interop issue caused due
to sending nss value 4 when firmware only supports nss value 2.
patch 8/9:
- Set the default return value to MODE_11AC_VHT160 for 160 MHz
to allow STA to connect to the AP even if it does not
explicitly indicate 160 MHz bandwidth support.
changes in v13:
- rebase
changes in v12:
- rebase
changes in v11:
patch 1/9:
- fix return values in ath12k_mac_set_he_txbf_conf() and
ath12k_mac_vif_recalc_sta_he_txbf()
patch 6/9:
- fix missing he_mcs initialization in ath12k_mac_init_arvif()
changes in v10:
patch 6/9:
- use ath12k_ahsta_to_sta()
- fix rcu_dereference warning in ath12k_mac_set_bitrate_mask_iter()
- change return type for ath12k_mac_validate_fixed_rate_settings()
- improve readability by adhering to nl80211 definitions of GI
NL80211_TXRATE_DEFAULT_GI. Introduce ath12k_mac_nlgi_to_wmigi()
for conversion.
patch 7/9:
- do not change default MODE_11AC_VHT160 in
ath12k_mac_get_phymode_vht() as it breaks clients which do not
set VHT_CAP_SUPP_CHAN_WIDTH_160MHZ.
patch 8/9:
- Use IEEE80211_VHT_CAP_EXT_NSS_BW_MASK along with
IEEE80211_VHT_CAP_SUPP_CHAN_WIDTH_160MHZ for determining VHT160
phymode.
changes in v9: rebase on top of master branch with mlo changes
patch 1/9 and 2/9:
- fetch link_conf using ath12k_mac_get_link_bss_conf()
instead of arvif->vif->bss_conf before mlo
patch 6/9
- fetch mcs/nss values from sta->link[] instead of sta->deflink
- fix spelling of 'incompatibility'
patch 8/9
- replace sta->deflink.addr with arsta->addr in
ath12k_peer_assoc_h_vht
patch 9/9
- replace sta->deflink.rx_nss with link_sta->rx_nss
changes in v8:
- rebase and resolve KASAN warnings reported by Jeff in v7, in patch 6/9.

Currently, only the HE IE in management frames is updated with
respect to MU-MIMO configurations, but this change is not
reflected in the hardware. Add support to propagate MU-MIMO
configurations to the hardware as well.
Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1

Currently, only the EHT IE in management frames is updated with
respect to MU-MIMO configurations, but this change is not
reflected in the hardware. Add support to propagate MU-MIMO
configurations to the hardware as well for AP mode. Similar
support for STA mode will be added in future.

Refactor the HE MCS mapper functionality in
ath12k_mac_copy_he_cap() into a new function.
This helps improve readability, extensibility and will be used
when adding support for 160 MHz bandwidth in subsequent patches.

on number of supported tx/rx chains and set them in supported
mcs/nss for HE capabilities.

Currently, the TX and RX MCS rate configurations per peer are
reversed when sent to the firmware. As a result, RX MCS rates
are configured for TX, and vice versa. This commit rectifies
the configuration to match what the firmware expects.

From: Pradeep Kumar Chitrapu @ 2025-07-01 1:04 UTC (permalink / raw)
To: ath12k; +Cc: linux-wireless, Pradeep Kumar Chitrapu, Muna Sinada
Add support to set fixed HE rate/GI/LTF values using nl80211.
Reuse parts of the existing code path already used for HT/VHT
to implement the new helpers symmetrically, similar to how
HT/VHT is handled.
Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1
Co-developed-by: Muna Sinada <quic_msinada@quicinc.com>

Clean up unused 80P80 references as hardware does not support
it. This is applicable to both QCN9274 and WCN7850.

To: ath12k; +Cc: linux-wireless, Pradeep Kumar Chitrapu, P Praneesh, Jeff Johnson
Add support to configure maximum NSS in 160 MHz bandwidth.
Firmware advertises support for handling NSS ratio information
as a part of service ready ext event using nss_ratio_enabled
flag. Save this information in ath12k_pdev_cap to calculate
NSS ratio.
Additionally, reorder the code by moving
ath12k_peer_assoc_h_phymode() before ath12k_peer_assoc_h_vht()
to ensure that arg->peer_phymode correctly reflects the bandwidth
in the max NSS calculation.

Currently rx and tx MCS map for 160 MHz under HE capabilities
are not updating properly, when 160 MHz is configured with NSS
lesser than max NSS support. Fix this by utilizing
nss_ratio_enabled and nss_ratio_info fields sent by firmware
in service ready event.
However, if firmware advertises EXT NSS BW support in VHT caps
as 1(1x2) and when nss_ratio_info indicates 1:1, reset the EXT
NSS BW Support in VHT caps to 0 which indicates 1x1. This is
to avoid incorrectly choosing 1:2 NSS ratio when using the
default VHT caps advertised by firmware.

Please mention that you are rectifying only for AP mode. For STA, current code is good.

It is not chip specific behavior, for now we believe it is mode behavior.

Since there are lingering questions about the 5/9 patch I plan to take 1-4,6-9
Given that there is ongoing discussion about the 5/9 patch logic in the
context of the ath11k driver, this patch can be posted again separately when
the discussions have concluded and the correct interpretation by firmware is
clear across all chipsets and interface types.
