HEXAGONRPCD(1)

💖 HEXAGONRPCD 💖

okay bestie, gather round, because this one is the server for FastRPC remote procedure calls from Qualcomm DSPs 🦋 no cap, that's literally the whole name and the whole vibe.

✨ SYNOPSIS ✨

hexagonrpcd [options...] -f DEVICE

so like, options go in, and -f DEVICE is basically mandatory, periodt 💅

---

🌸 DESCRIPTION 🌸

okay so. hexagonrpcd is a Server for FastRPC remote procedure calls from Qualcomm DSPs. that's it, that's the description, it's giving short and iconic and honestly? we respect it. 🎀

---

👑 OPTIONS 👑

• -c SHELL — Create a new pd running the specified ELF -d DSP DSP name (default: )
• -f DEVICE — the FastRPC device node to attach to 🔌
• -p PROGRAM — Run client program with shared file descriptor 🫶
• -R DIR — Root directory of served files (default: /usr/share/qcom/) 📁
• -s — Attach to sensorspd 🌡️

---

⭐ NOTES ⭐

so here's the tea ☕ hexagonrpcd serves files to the remote processor via a reverse tunnel interface to the remote processor. these files are by default searched for in:

these files are searched for in a directory tree, starting at the location defined by the -R option, or in /usr/share/qcom by default:

• acdb → /vendor/etc/acdbdata
• dsp → /vendor/dsp
• sensors/config → /vendor/etc/sensors/config
• sensors/registry → /mnt/vendor/persist/sensors/registry/registry
• sensors/sns_reg.conf → /vendor/etc/sensors/sns_reg_config
• socinfo → /sys/devices/soc0

bestie the left side is the HexagonRPCD file/dir and the right side is the Android file/dir, don't mix them up 💀

these files and directories should be populated with files from your device's Android firmware. (yes, your device's. go get 'em. 🧚)

if you can pass the -R option, the convention is to pass -R /usr/share/qcom/SOC/VENDOR/DEVICE, where SOC is the SoC name in lowercase, VENDOR is the capitalized name of the device vendor, and DEVICE is the device name 🦋 like for example:

-R /usr/share/qcom/sdm845/SHIFT/axolotl

or

-R /usr/share/qcom/sdm845/Thundercomm/db845c

see? lowercase soc, capitalized vendor, device name. it's giving organized. ate. 💅
