Hi all,
I faced a strange issue regarding MSI-X on my board.
A USB host (xchi_hcd) enables 5 MSI-X vectors out of 8.
The problem is other three vectors remain unmasked (at least, according
to dev->msi_vectors in Jailhouse), even if they store all-zeros. The PCI
spec says all vectors must be masked on reset (which sounds sane).
What's this? A bug in the kernel/driver? A config issue? Has anyone
tested Jailhouse in conjunction with MSI-X?
Best,
Valentine
