HM2_PCI(9)

💖 HM2_PCI 💖

okay bestie, welcome to hm2_pci — section 9 of the manual, HAL Component vibes, and she is the LinuxCNC HAL driver for Mesa Electronics PCI-based Anything IO boards running HostMot2 firmware. yes the name is giving very "cryptic acronym" but stay with me, she's iconic. 👑

✨ SYNOPSIS ✨

loadrt hm2_pci [config="str[,str...]"]

• config [default: ""] — the HostMot2 config strings, and if you wanna know what goes in them, go read the hostmot2(9) manpage, she explains it all, no cap. 🎀

🌸 DESCRIPTION 🌸

So here's the tea: hm2_pci is a device driver, and her whole job is interfacing Mesa's PCI and PC-104/Plus based Anything I/O boards (the ones with HostMot2 firmware living inside them) to the LinuxCNC HAL. it's giving matchmaker, but for hardware. 💅

The supported boards, in all their glory:

• the 5i20, 5i21, 5i22, 5i23, 5i24, and 5i25 — all of these are on PCI ✨
• the 4i65, 4i68, and 4i69 — these cuties are on PC-104/Plus 🦋
• the 3x20 — and this one needs a 6i68 or 7i68 carrier card to even show up
• the 6i25 — on PCI Express, fancy 🫶

Now, optionally (key word: optionally), the driver will program the board's FPGA with firmware when it registers that board with the hostmot2 driver. like, she'll flash it for you, bestie, that's the service. 💖

Which firmware gets loaded? That's decided by the config modparam, and the whole explanation lives in the hostmot2(9) manpage, specifically in the config modparam section. go read her, iykyk. 📖
