It's a gen 2 chip, similar to the RTL8723BU, but without Bluetooth. Features: 2.4 GHz, b/g/n mode, 1T1R, 150 Mbps. The vendor driver rtl8188fu version 4.3.23.6_20964.20170110 [0] was used as reference. The CD shipped with the device includes a newer driver, version 5.11.5-1-g12f7cde4b.20201102, but that one couldn't complete the WPA2 key exchange thing for whatever reason. [0] https://github.com/kelebek333/rtl8188fu Signed-off-by: Bitterblue Smith --- v3: - Address comments from Kalle Valo: - Use SPDX tags. - Make the arrays in rtl8188f_spur_calibration static const. - Make sure all comments have a space after /* and before */. - Put an empty line before some comments. - Avoid indenting a block in rtl8188fu_phy_iqcalibrate. - Move two macros outside of rtl8188f_enable_rf. - Remove an if whose condition was always true in rtl8188fu_config_channel. - Remove two unnecessary memcpy in rtl8188fu_parse_efuse. - Fix small mistakes in rtl8188fu_config_channel, rtl8188f_phy_lc_calibrate, and rtl8188fu_phy_iqcalibrate. v2: - Make some functions static, remove an unused variable. Reported-by: kernel test robot - Remove "The speed is not great yet, but it's usable." from the commit message. Other patches will improve the speed. --- .../net/wireless/realtek/rtl8xxxu/Makefile | 2 +- .../net/wireless/realtek/rtl8xxxu/rtl8xxxu.h | 56 + .../realtek/rtl8xxxu/rtl8xxxu_8188f.c | 1679 +++++++++++++++++ .../realtek/rtl8xxxu/rtl8xxxu_8192c.c | 1 + .../realtek/rtl8xxxu/rtl8xxxu_8192e.c | 1 + .../realtek/rtl8xxxu/rtl8xxxu_8723a.c | 1 + .../realtek/rtl8xxxu/rtl8xxxu_8723b.c | 3 +- .../wireless/realtek/rtl8xxxu/rtl8xxxu_core.c | 137 +- .../wireless/realtek/rtl8xxxu/rtl8xxxu_regs.h | 19 + 9 files changed, 1874 insertions(+), 25 deletions(-) create mode 100644 drivers/net/wireless/realtek/rtl8xxxu/rtl8xxxu_8188f.c diff --git a/drivers/net/wireless/realtek/rtl8xxxu/Makefile b/drivers/net/wireless/realtek/rtl8xxxu/Makefile index b278f8697cc0..c4ad5325f5e7 100644 --- a/drivers/net/wireless/realtek/rtl8xxxu/Makefile +++ b/drivers/net/wireless/realtek/rtl8xxxu/Makefile @@ -2,4 +2,4 @@ obj-$(CONFIG_RTL8XXXU) += rtl8xxxu.o rtl8xxxu-y := rtl8xxxu_core.o rtl8xxxu_8192e.o rtl8xxxu_8723b.o \ - rtl8xxxu_8723a.o rtl8xxxu_8192c.o + rtl8xxxu_8723a.o rtl8xxxu_8192c.o rtl8xxxu_8188f.o diff --git a/drivers/net/wireless/realtek/rtl8xxxu/rtl8xxxu.h b/drivers/net/wireless/realtek/rtl8xxxu/rtl8xxxu.h index 782b089a2e1b..9950a2ee00aa 100644 --- a/drivers/net/wireless/realtek/rtl8xxxu/rtl8xxxu.h +++ b/drivers/net/wireless/realtek/rtl8xxxu/rtl8xxxu.h @@ -35,6 +35,7 @@ #define REALTEK_USB_CMD_IDX 0x00 #define TX_TOTAL_PAGE_NUM 0xf8 +#define TX_TOTAL_PAGE_NUM_8188F 0xf7 #define TX_TOTAL_PAGE_NUM_8192E 0xf3 #define TX_TOTAL_PAGE_NUM_8723B 0xf7 /* (HPQ + LPQ + NPQ + PUBQ) = TX_TOTAL_PAGE_NUM */ @@ -43,6 +44,11 @@ #define TX_PAGE_NUM_LO_PQ 0x02 #define TX_PAGE_NUM_NORM_PQ 0x02 +#define TX_PAGE_NUM_PUBQ_8188F 0xe5 +#define TX_PAGE_NUM_HI_PQ_8188F 0x0c +#define TX_PAGE_NUM_LO_PQ_8188F 0x02 +#define TX_PAGE_NUM_NORM_PQ_8188F 0x02 + #define TX_PAGE_NUM_PUBQ_8192E 0xe7 #define TX_PAGE_NUM_HI_PQ_8192E 0x08 #define TX_PAGE_NUM_LO_PQ_8192E 0x0c @@ -859,6 +865,50 @@ struct rtl8192eu_efuse { u8 res12[0xc3];
