<p><span class="h-card" translate="no"><a href="https://mastodon.social/@whitequark" class="u-url mention">@<span>whitequark</span></a></span> Hi! Maybe you know. I want to make N channel PWM fan controller with tacho because on this motherboard fans are exposed only to BMC and you can’t control them from the host system. </p><p>What is the easiest/right way to expose it so it’s visible to lm-sensors? Basically I see two sane options: some kind of standard usb device type, but I couldn’t find that one (never done that). Or serial-over-usb + some custom protocol + kernel driver (never done that either, but I think I might pull this off). Third option is to skip driver part and directly shit over sysfs with files mimicking hwmon layout and just watch them with some script. But it feels fragile</p><p>What would you do? Thanks!</p>
