SubjectRe: [PATCH v6 1/9] PCI: Check for PCIe downtraining conditions
From: Alexandru Gagniuc <>
Date: Mon, 6 Aug 2018 18:25:35 -0500

> PCIe downtraining happens when both the device and PCIe port are
> capable of a larger bus width or higher speed than negotiated.
> Downtraining might be indicative of other problems in the system, and
> identifying this from userspace is neither intuitive, nor
> straightforward.
> The easiest way to detect this is with pcie_print_link_status(),
> since the bottleneck is usually the link that is downtrained. It's not
> a perfect solution, but it works extremely well in most cases.
