Ohh, that's impressive indeed!
But looking around with Google, it turns out the Altra Ampere PCIe is definitely quirky, see:

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, Geraldo Nascimento
