Hi list, I am working on verifying the ath9k_rfkill_poll_state() function. It would execute the ath_is_rfkill_set() the read the GPIO and change the LED. I found the POLL_INTERVAL would take 5 secs according the definition in net/rfkill/core.c #define POLL_INTERVAL (5 * HZ) So it would detect the GPIO status in every 5 seconds. But the ath9k I run in different platform, with the same modules, it works different way. The LED for one is working very fast, in another one is working so slow. I would like to clarify it is driver or BIOS issues. The way I come out is manually to change the GPIO status, see how the driver work. But so far I only found the devmen2 to access the specific address of GPIO. Any other good ways recommended ? And another question is the address defined in reg.h correct to access ? Such as #define AR_GPIO_IN (AR_SERV_9340(ah)) ? 0x402c : 0x404c) can I access the value of 0x404c directly? Thank you for your patience. :) -- 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
