Hello list! I'm playing around with BCM4313 support in b43. I've enabled CONFIG_B43_PHY_LCN and loaded the resulting module, which gives:
$ dmesg | grep b43 [ 161.209249] b43-phy1: Broadcom 4313 WLAN found (core revision 24) [ 161.210171] b43-phy1: Found PHY: Analog 10, Type 8 (LCN), Revision 1 [ 161.210185] b43-phy1 debug: Found Radio: Manuf 0x17F, Version 0x2064, Revision 1 [ 291.683651] b43-phy1: Loading firmware version 666.2 (2011-02-23 01:15:07) [ 291.685207] b43-phy1 ERROR: TX gain table unknown for this card [ 291.685213] b43-phy1 ERROR: SW ctl table is unknown for this card [ 291.711910] b43-phy1 debug: Chip initialized [ 291.712164] b43-phy1 debug: 64-bit DMA initialized [ 291.712323] b43-phy1 debug: QoS enabled [ 291.713781] b43-phy1 debug: Wireless interface started [ 291.713890] b43-phy1 debug: Adding Interface type 2 After which, `wpa_cli scan_results` doesn't list any networks. On the plus side, there haven't been any kernel panics ;). Since the “TX gain table unknown” error came first, I'm trying to figure out how brcmsmac handles this card, in the hope that I can just copy over the appropriate table. It looks like b43's b43_phy_lcn_load_tx_gain_table matches up pretty closely with brcmsmac's wlc_lcnphy_load_tx_gain_table, and there are a number of numbers hard-coded into b43's version that are #defined in brcmsmac: b43 brcmsmac ===== ============================== 0x140 LCNPHY_TX_PWR_CTRL_IQ_OFFSET 0xc0 LCNPHY_TX_PWR_CTRL_GAIN_OFFSET b43 versions of the two constants would probably be B43_LCNPHY_TX_PWR_CTRL_IQ_OFFSET and B43_LCNTAB_TX_PWR_CTRL_GAIN_OFFSET respecively, #defined in phy_lcn.h. There are likely other constants that could take advantage of similar naming. Should I work up a patch that does this, or are there b43/brcmsmac cross pollination issues that get in the way?
