Heya Linus,
Please git pull the following branch:
git pull git://git.kernel.org/pub/scm/linux/kernel/git/konrad/swiotlb.git stable/for-linus-5.11
which has a generic (but for right now engaged only with AMD SEV) mechanism to adjust a larger size SWIOTLB based on the total memory of the SEV guests which right now require the bounce buffer for interacting with the outside world. Normal knobs (swiotlb=XYZ) still work.
Thank you!!
