BHND_PMU(4)

💖 BHND_PMU(4) 💖

okay so bestie, this is the manual page for bhnd_pmu, which lives in section 4 of the kernel interfaces manual (that's the (4) bit, iykyk). it's giving "driver docs but make it cute" — let's get into it 🎀

---

✨ NAME ✨

bhnd_pmu — the Broadcom Home Networking Division PMU Driver. yes that's a whole mouthful, we're abbreviating it to "the PMU driver" from here on, periodt 💅

---

🌸 SYNOPSIS 🌸

so you wanna compile this driver into your kernel? iconic. literally just add this line to the kernel configuration file:

device bhnd

and if you'd rather load it as a module at boot instead (lowkey the easier route, ngl), add this line to loader.conf(5):

bhnd_load="YES"

that's it, that's the whole vibe check 🦋

---

⭐ DESCRIPTION ⭐

okay so here's the tea: the bhnd_pmu driver supports the Power Management Unit (PMU) — and that PMU is found in Broadcom Home Networking Division network chipsets and embedded systems. both. she contains multitudes 💜

and what does the PMU actually do?? the PMU provides a hardware interface for managing the device's clock and power topology. clock? managed. power topology? managed. main character energy, honestly 👑

ngl the ISC-licensed Linux PMU drivers from Broadcom did the original heavy lifting — this is the ported-to-FreeBSD-and-bhnd(4) glow-up of those 💖

and that's the whole page, bestie — this one's signed off from the Debian corner of the world, dated October 16, 2017 (yes, the footer says Debian, don't come for me, that's just what it says 💀). go manage some clocks and power topology, you got this 🌈💜
