Subject: [PATCH] vircpi: Add PCIe 5.0 and 6.0 link speeds
|
|
MIME-Version: 1.0
|
|
Content-Type: text/plain; charset=UTF-8
|

Content-Transfer-Encoding: 8bit

|
|
The PCIe 5.0 and PCIe 6.0 standards define new link speeds:
|
|
32GT/s and 64GT/s, respectively. Update our internal enum to
|
|
include these new speeds. Otherwise we format incorrect XML:
|
|
|
|
<pci-express>
|
|
<link validity='cap' port='0' speed='(null)' width='16'/>
|
|
<link validity='sta' speed='16' width='16'/>
|
|
</pci-express>
|
|
|
|
Like all "good" specifications, these are also locked behind a
|
|
login portal. But we can look at pciutils' source code: [1] and
|
|
[2].
