I agree, but I want to know why indirect descriptor needs to be disabled. The table can't be wrote by the device since it's not coherent swiotlb mapping.
I had all kinds of problems with uninitialized entries in the indirect table. So I gave up on it and concluded it would be too difficult to secure. -Andi _______________________________________________ Virtualization mailing list Virtualization@lists.linux-foundation.org https://lists.linuxfoundation.org/mailman/listinfo/virtualization
