From 52cc796d1c75ad176b8dc9259947da56be4a11a3 Mon Sep 17 00:00:00 2001 From: Laine Stump Date: Wed, 5 Oct 2016 11:26:07 -0400 Subject: [PATCH] qemu: allow 32 slots on pcie-expander-bus, not just 1 When I added support for the pcie-expander-bus controller in commit bc07251f, I incorrectly thought that it only had a single slot available. Actually it has 32 slots, just like the root complex aka pcie-root (the part that I *did* get correct is that unlike pcie-root a pcie-expander-bus doesn't allow any integrated endpoint devices - only pcie-root-ports and dmi-to-pci-controllers are allowed).
