Ohh, that's impressive indeed!
But looking around with Google, it turns out the Altra Ampere PCIe is
definitely quirky, see:
https://lore.kernel.org/linux-acpi/20200806225525.GA706347@bjorn-Precision-5520/T/
https://github.com/Tencent/TencentOS-kernel/commit/f454797b673c06c0eb1b77be20d8a475ad2fbf6f
The first quirk should probably be activated on Antonio's kernel but the
second one being a downstream Tencent patch, isn't. Alas, the second
quirk comes with a performance hit, see:

Thanks,
