I couldn't find anything useful in the BIOS, so tried iommu=soft on the
kernel command line. And that seems to have done the trick, we get
rotation info all the way through to the userspace, and the desktop
does it auto-rotate magic. Thanks for all your hard work.
On module inserion I have these messages if it is of any concern:-
pcie_mp2_amd 0000:04:00.7: MP2 device found [1022:15e4] (rev 0)
