From 6b45ded3f714e78c20708c0f29852fba856fec0c Mon Sep 17 00:00:00 2001 From: Richard Lyu Date: Tue, 6 Jan 2026 13:28:17 +0800 Subject: [PATCH] Documentation/x86: Update IOMMU spec references to use stable identifiers Direct URLs to vendor specifications for Intel VT-d and AMD IOMMU are frequently changed by vendors, leading to broken links in the documentation. Replace the fragile URLs with persistent identifiers, providing the official document titles and IDs. This ensures users can locate the relevant specifications regardless of vendor website restructuring.
