Patch Set #5, Line 30: switch (CONFIG_PCI_SEGMENT_GROUPS) {
Do we need to switch on this at all? the mcfg region is only supporting segment 0 anyway. […]
Yes, you are right that for Segment 0 we are mostly setting 256 hence removed 64/128 unused configuration.
But if we have 2 PCI segments
1. for all PCI device under host bridge
2. Dedicated for iTBT
In those case, don't we need to publish 2 dedicated MCFG table ? Looks like ACPI spec says so.
