[Qemu-devel] [PATCH] docs: pcie: Spell out machine type needs for PCIe features

[Kashyap Chamarthy <kchamart@redhat.com>]

PCIe features are available only via the Q35 machine for x86, or the
'virt' machine type for AArch64 architecture.

Mention that explicitly.

Thanks: Daniel Berrangé

+This applies to the Q35 machine type on x86 and the 'virt' machine type
+on AArch64 (in other words, PCIe features are available only when using

+machine types do not use PCI Express at this time.
