# AMD XRT (Xilinx Runtime) userspace library for NPU (XDNA 2) devices.
# AMD XRT + XDNA Shim — built together from amd/xdna-driver.
#
# This package builds the XRT base library from the commit pinned as a
# submodule in amd/xdna-driver. It provides:
# $out/lib/libxrt_coreutil.so — core utility library (linked by flm)
# $out/lib/libxrt_core.so — platform-independent core
# $out/include/xrt/ — public C++ headers
# This package produces:
# $out/lib/libxrt_coreutil.so — XRT core utility library
# $out/lib/libxrt_core.so — XRT platform-independent core
# $out/lib/xrt/module/
# libxrt_driver_xdna.so — XDNA NPU shim plugin
# $out/include/xrt/ — Public C++ headers
# $out/include/experimental/
# $out/bin/xrt-smi — System management tool
#
# The xrt source tree lives under the src/ subdirectory of the Xilinx/XRT
# repository (see src/CMakeLists.txt which includes CMake/nativeLnx.cmake).
# Build strategy
# ==============
# amd/xdna-driver is the canonical build system for the XDNA stack.
# It brings in Xilinx/XRT as a submodule and builds it with XRT_NPU=1,
# excluding PCIe/Alveo/edge components. Then it builds the XDNA shim
# (src/shim/) which links against libxrt_core + libxrt_coreutil.
#
# XRT version 2.19.0 — pinned to the commit used by amd/xdna-driver main
# as of 2026-03-25 (xrt @ 481583d).
# XRT itself has several required submodules that must be injected:
# src/runtime_src/core/common/aiebu — AIE binary utilities (NPU required)
# src/runtime_src/xdp — XRT Data Platform (profiling)
# src/runtime_src/core/common/elf — ELFIO header library
# src/runtime_src/core/common/gsl — Microsoft GSL headers
# src/runtime_src/aie-rt — AIE runtime
# aiebu itself has sub-submodules (aie-rt, ELFIO, cxxopts).
#
# Runtime note: this package only provides the userspace library. The
# kernel driver (amdxdna.ko) is a separate concern:
# • Linux >= 6.14 ships it in-tree (boot.kernelPackages.linux_latest).
# • Older kernels can use hardware.amdxdna.enable (once packaged).
# We build with -DSKIP_KMOD=1 so the kernel module (amdxdna.ko) is
# NOT compiled here — it ships in-tree since Linux 6.14.
#
# To update
# =========
# 1. Pin xdnaRev to the desired amd/xdna-driver commit.
# 2. Update xdnaHash: nix-prefetch-git --url .../xdna-driver --rev <REV>
# 3. Confirm the xrt submodule ref:
# curl -s "https://api.github.com/repos/amd/xdna-driver/contents/xrt?ref=<REV>" \
# | python3 -c "import sys,json; print(json.load(sys.stdin)['sha'])"
# 4. For each changed submodule, update the corresponding fetchFromGitHub below
# and re-run nix-prefetch-git to get the new hash.

longDescription = ''
XRT is the userspace component of AMD's XRT stack for their FPGA and
NPU devices. This package builds only the base library
(libxrt_coreutil, libxrt_core) that FastFlowLM links against to
communicate with the AMD XDNA 2 NPU via the amdxdna kernel driver.
AMD XRT (Xilinx Runtime) is the userspace runtime for AMD XDNA 2 NPU
devices (Ryzen AI — Strix Point, Strix Halo, Kraken Point, Gorgon Point).
The kernel driver (amdxdna.ko) is built in since Linux 6.14.
For older kernels it can be loaded via a DKMS package.
This package builds the XRT base libraries (libxrt_coreutil, libxrt_core)
together with the XDNA shim plugin (libxrt_driver_xdna) from the
amd/xdna-driver repository.
The kernel driver (amdxdna.ko) ships in-tree since Linux 6.14 and is
available for older kernels via a DKMS package. NPU firmware is
provided by the linux-firmware package (version >= 20260221 required).
Usage:
xrt-smi validate — validate the NPU setup end-to-end
xrt-smi examine — query the NPU device
