8922AE has more than one hardware version, and they use different BB MCU firmware, so occupy a byte from element priv[] to annotate version. Since there are more than one firmware and only matched version is adopted, return 1 to ignore not matched firmware. +===========================================+ | elm ID | elm size | version | | +----------+----------+----------+----------+ | | element_priv[] | +-------------------------------------------+ change to | v +===========================================+ | elm ID | elm size | version | | +----------+----------+----------+----------+ | | cv | element_rsvd[] | +-------------------------------------------+ Signed-off-by: Ping-Ke Shih <pkshih@xxxxxxxxxxx> --- drivers/net/wireless/realtek/rtw89/fw.c | 8 +++++++- drivers/net/wireless/realtek/rtw89/fw.h | 5 +++++ 2 files changed, 12 insertions(+), 1 deletion(-) diff --git a/drivers/net/wireless/realtek/rtw89/fw.c b/drivers/net/wireless/realtek/rtw89/fw.c index f9727c00d8b9..76c948da669e 100644 --- a/drivers/net/wireless/realtek/rtw89/fw.c +++ b/drivers/net/wireless/realtek/rtw89/fw.c @@ -401,10 +401,14 @@ int __rtw89_fw_recognize_from_elm(struct rtw89_dev *rtwdev, const union rtw89_fw_element_arg arg) { enum rtw89_fw_type type = arg.fw_type; + struct rtw89_hal *hal = &rtwdev->hal; struct rtw89_fw_suit *fw_suit; + if (hal->cv != elm->u.bbmcu.cv) + return 1; /* ignore this element */ + fw_suit = rtw89_fw_suit_get(rtwdev, type); - fw_suit->data = elm->u.common.contents; + fw_suit->data = elm->u.bbmcu.contents; fw_suit->size = le32_to_cpu(elm->size); return rtw89_fw_update_ver(rtwdev, type, fw_suit); @@ -820,6 +824,8 @@ int rtw89_fw_recognize_elements(struct rtw89_dev *rtwdev) goto next; ret = handler->fn(rtwdev, hdr, handler->arg); + if (ret == 1) /* ignore this element */ + goto next; if (ret) return ret; diff --git a/drivers/net/wireless/realtek/rtw89/fw.h b/drivers/net/wireless/realtek/rtw89/fw.h index 033ea4467876..f2b61e9ad8a7 100644 --- a/drivers/net/wireless/realtek/rtw89/fw.h +++ b/drivers/net/wireless/realtek/rtw89/fw.h @@ -3532,6 +3532,11 @@ struct rtw89_fw_element_hdr { __le32 data; } __packed regs[]; } __packed reg2; + struct { + u8 cv; + u8 priv[7]; + u8 contents[]; + } __packed bbmcu; struct { __le32 bitmap; /* bitmap of enum rtw89_fw_txpwr_trk_type */ __le32 rsvd; -- 2.25.1
