Qualcomm SCM, QSEECOM, and TrustZone firmware interfaces
Kernel-side glue for talking to the secure firmware that runs alongside the main OS on Qualcomm Snapdragon SoCs. It covers the Secure Channel Manager (SCM) call interface, the QSEECOM trusted-application gateway, and TrustZone shared-memory handling used by Snapdragon phones, tablets, and the new Snapdragon X-series Windows-on-ARM laptops.
recommendation
It should stay because this is live, actively maintained code underpinning current Qualcomm hardware, including 2024–2026 Snapdragon X Elite laptops like the Lenovo ThinkPad T14s, Dell XPS 13 9345, and ASUS Zenbook A14 (launched January 2025). The directory has seen roughly 93 substantive commits from 32 authors over the last five years with changes landing as recently as January 2026, and QSEECOM was only added in Linux 6.7, so this is a growing rather than shrinking corner of the tree.

codex reasoning notes (technical)
Local shell inspection (`rg`, `sed`) shows real platform-driver code for Qualcomm Secure Channel Manager, QSEECOM, and TZ shared-memory handling, not helper-only assets. Upstream vitality is strong from provided static history: 93 substantive commits in 5 years, most recent touch 2026-01-13, 32 authors, directory created in 2023 and still changing; no removal signal was found. I could not query lore directly because the advertised `lore-http` MCP server was unavailable and `lei` was not installed, so removal-discussion assessment is based on the supplied history plus absence of web-findable removal evidence.
