I've successfully built a coreboot firmware and Linux bootloader payload for the Chell Chromebook with Skylake, which then kexec's Xen / Qubes from the eMMC. Both of them are reporting that the IOMMU is not in use, and there is no DMAR entry in the ACPI table, which I believe is what they are looking for for enabling the IOMMU.
The Xen console prints: > (XEN) I/O virtualization disabled And qubes-hcl reports: > I/O MMU: Not active What's involved in enabling it? How soon in the boot process can it be turned on? -- Trammell -- coreboot mailing list: [email protected] https://www.coreboot.org/mailman/listinfo/coreboot
