So I finally got the time to test that solution. Compilation worked like a charm indeed, thanks. All seemed fine until I ran that code. Indeed the result of the division is completely off. :( For instance, if I have A = 17719, B = 44, then A / B gives C = 12886, instead of the expected 402. It is as though the result was multiplied by 32. At this point, it is much simpler for me to simply return both A and B, and to perform the division on the host's CPU instead of in the FW. Unless I commit some gross error and there is a more elegant solution around, I'll stick with that one, since I don't feel like debugging udivsi3_i4i. :/ Ignacy -- Information wants to be beer, or something like that. -- 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
