Subject: [PATCH] qemu: allow 32 slots on pcie-expander-bus, not just 1
|
|
|
127bba |
|
|
|
127bba |
When I added support for the pcie-expander-bus controller in commit
|
|
|
127bba |
bc07251f, I incorrectly thought that it only had a single slot
|
|
|
127bba |
available. Actually it has 32 slots, just like the root complex aka
|
|
|
127bba |
pcie-root (the part that I *did* get correct is that unlike pcie-root
|
|
|
127bba |
a pcie-expander-bus doesn't allow any integrated endpoint devices -
|
|
|
127bba |
only pcie-root-ports and dmi-to-pci-controllers are allowed).
