Qualcomm Snapdragon SoC interconnect (NoC) providers

Configures the network-on-chip fabric inside Qualcomm Snapdragon, SA, SC, QCS, and SDX SoCs, negotiating bandwidth between CPUs, GPUs, modems, and other blocks via Qualcomm's RPMh and SMD-RPM resource managers. These buses tie together Android phones, Snapdragon Windows laptops, automotive platforms, and 5G modems from the mid-2010s through 2025 flagships.

recommendation

It should stay in the kernel because these drivers describe the on-chip bus fabric of essentially every modern Qualcomm Snapdragon mobile and PC SoC, including chips Qualcomm was still launching in 2025 such as the Snapdragon 8 Elite Gen 5 and X1E80100-based Copilot+ PCs. Upstream activity is healthy, with ongoing rework and new platform support landing through 2025 and into 2026, and there is no replacement framework in sight.

  1. lore.kernel.org

    Upstream activity is current: April 22, 2026 patch adds QoS configuration support for the X1E80100 Qualcomm interconnect driver.

  2. lore.kernel.org

    The directory is seeing substantial 2025 rework on new Qualcomm platforms such as SM8750, indicating maintenance and platform enablement rather than retirement.

  3. qualcomm.com

    Qualcomm was still launching new Snapdragon 8-series mobile SoCs in 2025 for new flagship devices, showing the covered hardware family remains commercially current.

  4. qualcomm.com

    Qualcomm's Snapdragon X Elite PC platform maps to a currently deployed class of Qualcomm compute SoCs covered by this directory's recent X1E80100 support.

codex reasoning notes (technical)

Real driver directory: local Kconfig inspection shows many Qualcomm SoC-specific interconnect drivers under INTERCONNECT_QCOM. Lore evidence was obtained with mcp__lore_http__.lore_file_timeline/lore_activity on representative current files (x1e80100.c, sm8750.c); results show active feature work and refactoring through 2026, not removal. A subject-only removal/deprecation lore_regex query timed out, and a fallback lei query failed due local daemon permission errors; no removal evidence was found in the successful lore samples. Deployment judgment is based on official Qualcomm product-release pages found with web.search_query, which show new Snapdragon mobile and PC SoCs in 2025 and ongoing relevance of the same interconnect-driver family. No natural replacement exists: these are platform-specific Qualcomm NoC provider drivers, not a legacy stack superseded by another upstream driver.
