For systems that have 256 logical CPU cores or more (e.g., 64-core AMD EPYC™ 7763 in a dual-socket configuration and SMT enabled), setting the input-output memory management unit (IOMMU) configuration to “disabled” can limit the number of available logical cores to 255. The reason i...

Edit 2: Just after the previous update I got it to do it again, it never disconnected my webcam which is the only device on the other xHCI controller (PCI Bus 13) but it disconnected everything on the other other xHCI controller (PCI Bus 1). It said the DEVICE_QUALIFIER_DESCRIPTOR's...
IOMMU improperly handles certain special address ranges with invalid device table entries (DTEs), which may allow an attacker with privileges and a compromised Hypervisor (HV) to induce DTE faults to bypass RMP checks in SEV-SNP, potentially leading to a loss of guest integrity. CVE-2021-46746...

IOMMU is an extension to AMD64 architecture to support address translation and access protection on DMA transfers. Together, virtualization software runs more securely and efficiently enabling a better experience when dealing with virtual systems. Security for User Level application and Virtual Machine ...
And I have been told "AMD-Vi: Completion-Wait loop timed out" reported by IOMMU because of no response from the IO device, in my case, it is Intel X710 2x10GbE SFP+ Adapter, running with Debian 11 and Inbox driver for Intel X710. The failing system had LACP b...
