AMD IOMMU + SME + amdgpu regression
Hi,
amdgpu + IOMMU + SME is now working for me on 5.7, yay! But, it is
broken on torvalds master, boo. On boot, depending on which exact commit
I test, it either hangs immediately (with built-in driver, before
starting initramfs), displays some errors then hangs, or spams the
screen with many amdgpu errors.
I bisected the black screen hang to:
commit dce8d6964ebdb333383bacf5e7ab8c27df151218
