Yep, fixed in v2. (I actually did that first in v1 and removed it — as I saw the captialized variant used througout the doc. But I see you're asking to be consistent in the sentence.) > > +on AArch64 (in other words, PCIe features are available only when using > > +the Q35 and 'virt' machine types for the said architectures).

But I wanted to put some wording that is unambiguous about the mandatory requirements. How about this, that I currently have in my v2 draft: "Note that the PCIe features are available only when using the 'q35' machine type on x86 architecture and the 'virt' machine type on AArch64. Other machine types do not use PCIe at this time." Thanks for the quick review!

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 Signed-off-by: Kashyap Chamarthy <kchamart@redhat.com> --- docs/pcie.txt | 10 ++++++++-- 1 file changed, 8 insertions(+), 2 deletions(-)
