Hi all,
To preserve PCIe performance, ACS is enabled only when
AMD IOMMU is not disabled.
[This text serves solely as the patch changelog.]
Thanks,

v1: https://lore.kernel.org/all/20250928075257.1542-1-guojinhui.liam@bytedance.com/
Changelog in v1 -> v2 (suggested by Suravee):
- Drop the amd_iommu_force_enable check; it's only used
to skip a workaround in the same function.
