First, tks for the answer, Dan. > little broken with -DDBG_RX_SIGNAL_DISPLAY_RAW_DATA, maybe we can > fix that in a next patch. > How is it broken? make -j<> ./drivers/staging/rtl8723bs/r8723bs.ko EXTRA_CFLAGS="-DDBG_RX_SIGNAL_DISPLAY_RAW_DATA" drivers/staging/rtl8723bs/hal/hal_com.c: In function ‘rtw_store_phy_info’: drivers/staging/rtl8723bs/hal/hal_com.c:927:43: error: ‘PODM_PHY_INFO_T’ undeclared (first use in this function) 927 | struct odm_phy_info *pPhyInfo = (PODM_PHY_INFO_T)(&pattrib->phy_info); | ^~~~~~~~~~~~~~~ drivers/staging/rtl8723bs/hal/hal_com.c:927:43: note: each undeclared identifier is reported only once for each function it appears in drivers/staging/rtl8723bs/hal/hal_com.c:940:73: error: ‘struct odm_phy_info’ has no member named ‘RxPwr’; did you mean ‘rx_pwr’? 940 | psample_pkt_rssi->ofdm_pwr[rf_path] = pPhyInfo->RxPwr[rf_path]; | ^~~~~ | rx_pwr drivers/staging/rtl8723bs/hal/hal_com.c:941:71: error: ‘struct odm_phy_info’ has no member named ‘RxSNR’ 941 | psample_pkt_rssi->ofdm_snr[rf_path] = pPhyInfo->RxSNR[rf_path]; Actually it's not exaclty in the same line of pr_debug/netdev_dbg replacement. Do you think we can do the replacement at: > + pr_debug(", rx_ofdm_pwr:%d(dBm), rx_ofdm_snr:%d(dB)\n",... regardless of this build errors?

Ok. > - printk(KERN_CRIT "%s: sdio_claim_irq FAIL(%d)!\n", __func__, err); > + pr_crit("%s: sdio_claim_irq FAIL(%d)!\n", __func__, err); > ^^^^^^^? Originally, I didn't replace this because at dvobj of sdio_alloc_irq(struct dvobj_priv *dvobj) there are two adapter fields: struct dvobj_priv { struct adapter *if1; /* PRIMARY_ADAPTER */ ... struct adapter *padapters; ... } Checking the "counter part" function of sdio_alloc_irq(), the sdio_free_irq() (which is not used), the if1 (primary) is used for debug purpose: netdev_err(dvobj->if1->pnetdev... And checking the initialization path, if1 should be ok at this point. But since I can't test this, do you suggest to replace anyway? Tks and regards.
