RTL8733BU (not supported in rtw88) is 11n but its MCU is the RTW_WCPU_11AC type. I was thinking to rename them: RTW_WCPU_11N -> RTW_WCPU_8051 RTW_WCPU_11AC -> RTW_WCPU_3081 8051 and 3081 are the names used in the vendor drivers: #define PHYDM_IC_8051_SERIES (ODM_RTL8881A | ODM_RTL8812 | ODM_RTL8821 |\ ODM_RTL8192E | ODM_RTL8723B | ODM_RTL8703B |\ ODM_RTL8188F | ODM_RTL8192F | ODM_RTL8721D |\ ODM_RTL8710C) #define PHYDM_IC_3081_SERIES (ODM_RTL8814A | ODM_RTL8822B | ODM_RTL8197F |\ ODM_RTL8821C | ODM_RTL8195B | ODM_RTL8198F |\ ODM_RTL8822C | ODM_RTL8812F | ODM_RTL8814B |\ ODM_RTL8197G) > Acked-by: Ping-Ke Shih <pkshih@xxxxxxxxxxx> > > [1] https://www.realtek.com/Product/Index?id=577&cate_id=194 > [2] https://www.realtek.com/Product/Index?id=590&cate_id=194 > >> --- >> drivers/net/wireless/realtek/rtw88/sdio.c | 14 ++++++++++++-- >> 1 file changed, 12 insertions(+), 2 deletions(-) >> >> diff --git a/drivers/net/wireless/realtek/rtw88/sdio.c b/drivers/net/wireless/realtek/rtw88/sdio.c >> index c57f683d9af8..71cbe49b6c59 100644 >> --- a/drivers/net/wireless/realtek/rtw88/sdio.c >> +++ b/drivers/net/wireless/realtek/rtw88/sdio.c >> @@ -677,12 +677,22 @@ static void rtw_sdio_enable_rx_aggregation(struct rtw_dev *rtwdev) >> { >> u8 size, timeout; >> >> - if (rtw_chip_wcpu_11n(rtwdev)) { >> + switch (rtwdev->chip->id) { >> + case RTW_CHIP_TYPE_8703B: >> + case RTW_CHIP_TYPE_8821A: >> + case RTW_CHIP_TYPE_8812A: >> size = 0x6; >> timeout = 0x6; >> - } else { >> + break; >> + case RTW_CHIP_TYPE_8723D: >> + size = 0xa; >> + timeout = 0x3; >> + rtw_write8_set(rtwdev, REG_RXDMA_AGG_PG_TH + 3, BIT(7)); >> + break; >> + default: >> size = 0xff; >> timeout = 0x1; >> + break; >> } >> >> /* Make the firmware honor the size limit configured below */ >> -- >> 2.49.0 >
