Linus Torvalds noted the new AMD DCN6 register headers and accompanying code for upcoming GPU hardware account for roughly a third of the rc1 patch diff. A cloc analysis shows drivers/gpu/drm/amd now totals 6.52 million lines, up from 6.35 million in 7.2, making the modern AMD graphics driver about 16% of the entire kernel codebase. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How many lines of code is the Linux kernel at version 7.3-rc1? Linux 7.3-rc1 measures about 40.98 million lines total, according to a cloc analysis of the git tree, up from 40.42 million lines in the Linux 7.2 release. The total splits into roughly 5.13 million blank lines, 4.91 million comment lines, and 30.94 million lines of actual code. _Track kernel growth and driver changes release by release on daily.dev._ ### Why did the Linux 7.3-rc1 kernel patch size grow so much? The growth comes mainly from AMD's new DCN6 display register headers and accompanying driver code for upcoming graphics hardware IP blocks. Linus Torvalds noted this AMD GPU code and header dump accounts for about a third of the entire 7.3-rc1 patch diff, following a recurring pattern of large AMD register dumps in past kernel releases. _Developers following AMD GPU driver internals can keep up with kernel changes via daily.dev._ ### How many lines of code make up the AMD kernel graphics driver in Linux? The drivers/gpu/drm/amd directory, covering the AMDGPU kernel graphics driver, AMDKFD compute driver, and related display code, totals 6.52 million lines in Linux 7.3-rc1, up from 6.35 million lines in Linux 7.2. This excludes the older Radeon DRM driver, and means roughly 16% of the entire Linux kernel is now modern AMD graphics driver code. _Anyone gauging AMD driver footprint in the kernel can follow these stats on daily.dev._ ## Similar posts on daily.dev - [Linux 7.2 Surpasses More Than 43 Million Lines In The Kernel Tree](https://daily.dev/posts/linux-7-2-surpasses-more-than-43-million-lines-in-the-kernel-tree-np8wbtqhn) · Phoronix · 0 upvotes · 0 comments --- Tags: [#linux](https://daily.dev/tags/linux), [#gpu](https://daily.dev/tags/gpu), [#amd](https://daily.dev/tags/amd) [View this post on daily.dev](https://daily.dev/posts/linux-7-3-rc1-close-to-41-million-lines-amd-kernel-graphics-driver-at-6-5-million-lines-b5rgkkosv) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Linux 7.3-rc1 Close To 41 Million Lines, AMD Kernel Graphics Driver At 6.5 Million Lines","url":"https://daily.dev/posts/linux-7-3-rc1-close-to-41-million-lines-amd-kernel-graphics-driver-at-6-5-million-lines-b5rgkkosv","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/linux-7-3-rc1-close-to-41-million-lines-amd-kernel-graphics-driver-at-6-5-million-lines-b5rgkkosv"},"datePublished":"2026-08-31T00:24:34.305Z","dateModified":"2026-08-31T00:25:27.924Z","description":"Linux 7.3-rc1 has grown to nearly 41 million lines, up from 40.42 million in 7.2, largely driven by AMD's kernel graphics driver code.
