Just read MACCTL unconditionally. It obviously is just used for bus posting.
We usually also add a comment.
b43_read32(dev, B43_MMIO_MACCTL); /* flush writes */

I'd like to put a bg questionmark on this.
We already have SHM access. Your function does exactly the same, except that it
accesses the bullshit register h165.

WMI (Windows Management Interface) > code handles the functions of the top row of your keyboard that are > generated by a fn+FX key. The BIOS is rarely if ever involved in any of this. As was already explained, the rfkill signal is an electrical input to the wifi hardware, and the b43 driver can only ever read the state of this input. Who drives the signal depends on the unique system design. (Think mainboard.) In laptops there is always at least one "embedded controller" AKA EC which handles some or all of keyboard, GPIO signals, LEDs, Fn keys, lid switch, power switch, special function keys, fan control, battery charging and various other bits and pieces of the system. Bytecode within the ACPI tables in the BIOS may be executed by the kernel in order to discover e.g. Fn+key combination presses or lid switch, but the BIOS does not have anything to do with changing the electrical signal going out from the EC - that is done either by the EC firmware (in response to some keypress, which will also be reported via ACPI so the OS can update some status display) or as ordered by the operating system (in response to some keypress reported by the EC via ACPI). There is no standardization at all for these signals and this behavior. If you can find the schematics for your laptop that would help. //Peter ___ Bcm43xx-dev mailing list Bcm43xx-dev@lists.berlios.de https://lists.berlios.de/mailman/listinfo/bcm43xx-dev

I think another point which is also really important is to EXTENSIVELY TRIM messages that you reply to. It is quite common that Gmail users include the full previous history of a thread in every reply they create and this is absolute madness! Please be more aware of how you post, and make sure to trim when sending replies. Some particular behavior of Gmail (maybe it hides old parts of the thread?) is not an excuse for you to waste everyone else's time! //Peter ___ Bcm43xx-dev mailing list Bcm43xx-dev@lists.berlios.de https://lists.berlios.de/mailman/listinfo/bcm43xx-dev
