# This PKGBUILD can also be used to install *Vitis Unified Software Platform*.
# See `package()` for details.

# BUILD INSTRUCTIONS:
#
# 1. Go to https://www.xilinx.com/support/download/index.html/content/xilinx/en/downloadNav/vivado-design-tools.html
# 2. Download "AMD Unified Installer for FPGAs & Adaptive SoCs SFD" - WARNING:
#   (1) This file is >100GB in size  (2) You need an account for US export
# controls. 3. Place the .tar.gz in the same directory as the PKGBUILD
# 4. Build!
#
# No refunds for broken AUR helpers, just use make(chroot)pkg.
#
# SOME MORE NOTES:
#
# This package is huge. The download alone is a barely-compressed >100GB
# .tar.gz (extracts to ~100GB) and the final zstd-compressed package is another
# 20GB. Reserve at least 200GB in total for building.
#
# It can also take up to two hours to build, being mostly limited by I/O and
# single-thread performance. `namcap` takes another 30 minutes, make sure
# you're not running that automatically.
#
# It *also* requires a reasonably ugly hack to build: since package() is run
# under fakeroot, and the installer tries to access the home directory no
# matter what `--location` is set to, it fails during "Running post-install
# tasks" because it tries to access `/root`. To fix this, a tiny shared library
# (see spoof_homedir.c) is LD_PRELOADed. Its only job is to wrap the
# `getpwuid()` function and modify the original return value for uid==0.
