Has anything changed from 11.2 to 12.0 in PCI MSI/MSIX path?

Hi,

I have a amd64 based board. When I tried to boot 11.1 (or) 11.2 in that, I
needed the following tunables to be set from loader prompt to get it booted
(otherwise machine reboots continuously).

hw.usb.xhci.msi=0
hw.usb.xhci.msix=0
hw.pci.enable_msi=0
hw.pci.enable_msix=0

But, when I tried with 12.0 - ALPHA4, I could able to get it booted without
any tunables.  So, has anything changed significantly on PCI MSI/MSI-X
path?

Note: I have a forum topic with my observations about the issue on
11.1/11.2 in the following thread
https://forums.freebsd.org/threads/freebsd-11-1-installation-fails-and-rebooting.65814/

Let me know if you need any details.
