Apparently, IOMMU reinforce wasn’t to be had in Intel’s Skylake processors that powered Purism’s Librem laptops, however it is supported via the coreboot firmware, previously referred to as LinuxBIOS, so the corporate needed to update its laptops to the latest coreboot release, which shall we customers set up Qubes OS four.zero with none warnings.

“Starting with Qubes 4.0, the installer will warn users if their computers do not support certain CPU features such as IOMMU. While you can ignore the warning and complete the install, certain VMs with PCI devices attached such as sys-net and sys-usb will not start unless you change their virtualization mode from HVM to PV, bypassing the protections IOMMU provides,” says Kyle Rankin.

Purism says that it is these days nonetheless checking out the brand new coreboot symbol with IOMMU reinforce for its Librem laptops, and can quickly begin to be offering it with all new computer shipments. Therefore, if you wish to purchase a Librem computer from Purism and need to set up Qubes OS four.zero on it, you will have to wait a bit extra for the up to date line-up.

Meanwhile, it seems like Purism plans upload coreboot reinforce for TPM (Trusted Platform Module) to its Librem laptops, and use the TMP with Heads era to provide consumers tamper-proofing in opposition to malware that might compromise the kernel, bootloader, or even the BIOS in their Linux-powered laptops.
