Extend ath12k_mac_op_set_bitrate_mask() to handle EHT rates. Create and pass EHT mask containing MCS and NSS along with EHT GI and LTF when calling ath12k_mac_set_rate_params() Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1 Co-developed-by: Aaradhana Sahu Signed-off-by: Aaradhana Sahu Signed-off-by: Muna Sinada --- drivers/net/wireless/ath/ath12k/mac.c | 55 +++++++++++++++++++++++++-- 1 file changed, 52 insertions(+), 3 deletions(-) diff --git a/drivers/net/wireless/ath/ath12k/mac.c b/drivers/net/wireless/ath/ath12k/mac.c index 732ddd78635d..31b0e641ce55 100644 --- a/drivers/net/wireless/ath/ath12k/mac.c +++ b/drivers/net/wireless/ath/ath12k/mac.c @@ -12517,6 +12517,38 @@ ath12k_mac_he_mcs_range_present(struct ath12k *ar, return true; } +static bool +ath12k_mac_eht_mcs_range_present(struct ath12k *ar, + enum nl80211_band band, + const struct cfg80211_bitrate_mask *mask) +{ + u16 eht_mcs; + int i; + + for (i = 0; i < NL80211_EHT_NSS_MAX; i++) { + eht_mcs = mask->control[band].eht_mcs[i]; + + switch (eht_mcs) { + case 0: + case BIT(8) - 1: + case BIT(10) - 1: + case BIT(12) - 1: + case BIT(14) - 1: + break; + case BIT(15) - 1: + case BIT(16) - 1: + case BIT(16) - BIT(14) - 1: + if (i != 0) + return false; + break; + default: + return false; + } + } + + return true; +} + static void ath12k_mac_set_bitrate_mask_iter(void *data, struct ieee80211_sta *sta) { @@ -12644,6 +12676,7 @@ ath12k_mac_op_set_bitrate_mask(struct ieee80211_hw *hw, const u8 *ht_mcs_mask; const u16 *vht_mcs_mask; const u16 *he_mcs_mask; + const u16 *eht_mcs_mask; u8 he_ltf = 0; u8 he_gi = 0; u8 eht_ltf = 0, eht_gi = 0; @@ -12671,6 +12704,7 @@ ath12k_mac_op_set_bitrate_mask(struct ieee80211_hw *hw, ht_mcs_mask = mask->control[band].ht_mcs; vht_mcs_mask = mask->control[band].vht_mcs; he_mcs_mask = mask->control[band].he_mcs; + eht_mcs_mask = mask->control[band].eht_mcs; ldpc = !!(ar->ht_cap_info & WMI_HT_CAP_LDPC); sgi = mask->control[band].gi; @@ -12722,9 +12756,10 @@ ath12k_mac_op_set_bitrate_mask(struct ieee80211_hw *hw, ath12k_warn(ar->ab, "failed to update fixed rate settings due to mcs/nss incompatibility\n"); - mac_nss = max3(ath12k_mac_max_ht_nss(ht_mcs_mask), - ath12k_mac_max_vht_nss(vht_mcs_mask), - ath12k_mac_max_he_nss(he_mcs_mask)); + mac_nss = max(max3(ath12k_mac_max_ht_nss(ht_mcs_mask), + ath12k_mac_max_vht_nss(vht_mcs_mask), + ath12k_mac_max_he_nss(he_mcs_mask)), + ath12k_mac_max_eht_nss(eht_mcs_mask)); nss = min_t(u32, ar->num_tx_chains, mac_nss); /* If multiple rates across different preambles are given @@ -12772,6 +12807,20 @@ ath12k_mac_op_set_bitrate_mask(struct ieee80211_hw *hw, ret = -EINVAL; goto out; } + + num_rates = ath12k_mac_bitrate_mask_num_eht_rates(ar, band, + mask); + if (num_rates == 1) + eht_fixed_rate = true; + + if (!ath12k_mac_eht_mcs_range_present(ar, band, mask) && + num_rates > 1) { + ath12k_warn(ar->ab, + "Setting more than one EHT MCS Value in bitrate mask not supported\n"); + ret = -EINVAL; + goto out; + } + ieee80211_iterate_stations_mtx(hw, ath12k_mac_disable_peer_fixed_rate, arvif); -- 2.34.1
