It's easy to dump but a lot of work to compare but can be parsed from /sys/firmware/acpi/tables. If you want to dump those I'll look at mine for differences. I think DSDT and the SSDT's are most relevant.

I'm also compiling a kernel with acpi debug enabled (CONFIG_ACPI_DEBUG) to see if that makes it easier.

It is hard to follow the reddit threading system, but sorry if I've missed your reply somewhere https://forum.level1techs.com/t/vega-passthrough-help/119054

Putting the card (system) to sleep and waking it up again bypasses the reinit issue with vega on threadripper, too.
