So two solutions came to my mind:
1. rewrite DSDT generation into C
You might want have a look at DynamicTablesPkg/ for that
Wasn't is involving using ConfigurationManager? Or maybe I just had
wrong assumption after reading code.
2. provide EHCI/XHCI in SSDT table instead of DSDT
Should work, except that I'd suggest to worry about xhci only.
ehci never actually worked anyway, so why advertise it to the OS in the
first place?
Good point.
3. Add a _STA AML function to the XHCI DSDT description, which is able
to figure whenever XHCI is present.
We had that in qemu years ago, before switching to full DSDT generation,
where the _STA functions checked some bit in PCI config space of the ISA
bridge to figure whenever specific isa devices (floppy, serial/parallel
port) are present or not.
Will look.
Thanks.
