I'm not convinced the swiotlb use describe there falls under "intended
use" - mapping a 1280x720 framebuffer in a single chunk? (As an aside,
the bottom of this page is also confusing, as following "Then we can
confirm the modified swiotlb size in the boot log:" there is a log
fragment showing the same original size of 64Mb.
It doesn't. We also do not add hacks to the kernel for whacky out
of tree modules.
Also, Option 1 listed in the webpage seems to be a lot better. Any
reason you can't do that? Because that option both solves the problem
and increases performance.
