Hi all,
When interrupt remapping support was introduced first in Jailhouse for
VT-d, we gained union x86_msi_vector.remap and related struct in union
ioapic_redir_entry. Both are in vendor-neutral x86 code.
Do I get correctly that in fact the layout of this structure is VT-d
specific? On AMD, interrupt remapping tables are indexed with 10 lowest
bits of MSI data (Sect 2.2.5.1 in the spec), and we don't seem to touch
this part in Jailhouse. You may find relevant code in the Linux kernel
at [1]
Is it true, or am I missing something?

Best,
Valentine
