# Adapted directly from the OnePlus 7 Pro hotdog bring-up at the pinned commit.

%description
Userspace FastRPC bridge and system services for Qualcomm remote processors on
Xiaomi Pad 5 (nabu). The Nabu build adds the writable file operations and
larger listener input buffer required by the DSP-hosted sensor registry. The
daemon remains unprivileged and its SDSP service is restricted to the Nabu
hexagonfs root.
