Hi all, I am testing some custom algorithms for powersaving using mac80211/ath5k. I am using Dlink DWL-AG660 PCMCIA cards for my experiments. For these algorithms I am notifying sleep/awake events from mac80211 down to the driver whenever I want to. For the case of ath5k I followed that code madwifi was using to force the chipset to sleep (full sleep mode), find the piece of code below: The problem is, the card (and the laptop) totally freezes whenever this is done. According to http://madwifi-project.org/wiki/Compatibility/D-Link this card uses a AR5212, and madwifi driver does use this piece of code to force the chip to sleep (in that case when resetting or stopping an interface). Undoubtedly, I am missing something I should take care of. I'd appreciate any "clue" you could give me. /**** CODE *****/ struct ath5k_softc *sc = hw->priv; struct ath5k_hw *ah = sc->ah; unsigned int i; u32 staid, data; staid = ath5k_hw_reg_read(ah, AR5K_STA_ID1); ath5k_hw_reg_write(ah, AR5K_SLEEP_CTL_SLE_ALLOW, AR5K_SLEEP_CTL); staid |= AR5K_STA_ID1_PWR_SV; ath5k_hw_reg_write(ah, staid, AR5K_STA_ID1); /**** CODE *****/ Thanks in advance, Andrés -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
