Rewriting the scheduler explains the bloat: The new nvlddmkm.sys (Windows) and nvidia.ko (Linux) binaries are 18% larger than the previous version. This is not a maintenance patch; it is a foundation reboot. We obtained an internal draft of the full patch notes that NVIDIA chose to omit from the public release. Here are the most critical lines: "Fixed a race condition where cudaMalloc would return a null pointer if the system had been up for more than 49.7 days without a reboot on AMD Threadripper platforms."
This is an —specifically the unannounced features, the silent performance regressions, and the architectural shifts of the R550+ driver branch (version 555.85.05 and its enterprise siblings). The "Stealth" Update: R555.85.05 Breakdown Two weeks ago, NVIDIA quietly pushed a new Production Branch driver to its developer portal without a typical blog post fanfare. Our analysis of the release notes (or lack thereof) reveals a build that is less about game-ready optimizations and entirely focused on two things: AI inference latency and virtualized memory paging . cuda driver release news exclusive
"Addressed a vulnerability (CVE-2024-0XXX) where a malicious shader could read cross-process L2 cache residuals. Score: 7.8 High." Rewriting the scheduler explains the bloat: The new nvlddmkm
