All USB devices supported by rtw88 have the same problem: they don't transmit beacons in AP mode. The cause appears to be clearing BIT_EN_BCNQ_DL of REG_FWHW_TXQ_CTRL before uploading the beacon reserved page, so don't clear the bit for USB devices. Tested with RTL8811CU and RTL8723DU. Cc: stable@xxxxxxxxxxxxxxx # 6.6.x Signed-off-by: Bitterblue Smith <rtl8821cerfe2@xxxxxxxxx> --- I'm not sure if SDIO devices have the same problem. Also, should BIT_EN_BCNQ_DL ever be cleared in this function? The relevant code is disabled in all these drivers: https://github.com/morrownr/8821cu-20210916/blob/3eacc28b721950b51b0249508cc31e6e54988a0c/hal/rtl8821c/rtl8821c_ops.c#L1603 https://github.com/tomaspinho/rtl8821ce/blob/f119398d868b1a3395f40c1df2e08b57b2c882cd/hal/rtl8821c/rtl8821c_ops.c#L1668 https://github.com/alireza-tabatabaee/RTL8821CS/blob/2d8a102dd7399a243f11b13314c299e509cc4ef1/rtl8821cs/hal/rtl8821c/rtl8821c_ops.c#L1603 https://github.com/morrownr/88x2bu-20210702/blob/3c8f59b5b05e5090e8593da1940a8d3ccac3f878/hal/rtl8822b/rtl8822b_ops.c#L1771 https://github.com/thales-dis-dr/rtl8822CU/blob/4182c79e0c5362dcea46088dab9fed27795b5579/hal/rtl8822c/rtl8822c_ops.c#L1941 --- drivers/net/wireless/realtek/rtw88/fw.c | 13 ++++++++----- 1 file changed, 8 insertions(+), 5 deletions(-) diff --git a/drivers/net/wireless/realtek/rtw88/fw.c b/drivers/net/wireless/realtek/rtw88/fw.c index ab7d414d0ba6..782f3776e0a0 100644 --- a/drivers/net/wireless/realtek/rtw88/fw.c +++ b/drivers/net/wireless/realtek/rtw88/fw.c @@ -1468,10 +1468,12 @@ int rtw_fw_write_data_rsvd_page(struct rtw_dev *rtwdev, u16 pg_addr, val |= BIT_ENSWBCN >> 8; rtw_write8(rtwdev, REG_CR + 1, val); - val = rtw_read8(rtwdev, REG_FWHW_TXQ_CTRL + 2); - bckp[1] = val; - val &= ~(BIT_EN_BCNQ_DL >> 16); - rtw_write8(rtwdev, REG_FWHW_TXQ_CTRL + 2, val); + if (rtw_hci_type(rtwdev) != RTW_HCI_TYPE_USB) { + val = rtw_read8(rtwdev, REG_FWHW_TXQ_CTRL + 2); + bckp[1] = val; + val &= ~(BIT_EN_BCNQ_DL >> 16); + rtw_write8(rtwdev, REG_FWHW_TXQ_CTRL + 2, val); + } ret = rtw_hci_write_data_rsvd_page(rtwdev, buf, size); if (ret) { @@ -1496,7 +1498,8 @@ int rtw_fw_write_data_rsvd_page(struct rtw_dev *rtwdev, u16 pg_addr, rsvd_pg_head = rtwdev->fifo.rsvd_boundary; rtw_write16(rtwdev, REG_FIFOPAGE_CTRL_2, rsvd_pg_head | BIT_BCN_VALID_V1); - rtw_write8(rtwdev, REG_FWHW_TXQ_CTRL + 2, bckp[1]); + if (rtw_hci_type(rtwdev) != RTW_HCI_TYPE_USB) + rtw_write8(rtwdev, REG_FWHW_TXQ_CTRL + 2, bckp[1]); rtw_write8(rtwdev, REG_CR + 1, bckp[0]); return ret; -- 2.45.2
