%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.

- Add DSP-served file write, remove and extended rename operations from the
  pinned Hotdog bring-up patch set.
- Increase the listener input buffer from 256 bytes to 64 KiB and run the
  upstream Meson tests during the RPM build.
- Preserve the unprivileged fastrpc service and Nabu-specific SDSP root.
