The improvement comes via a new 'Apple MGR misc controls' driver (apple-pmgr-misc) that adjusts global power states including fabric and memory controller power states. Originally written by Asahi Linux founder Hector Martin, the driver was submitted for mainline inclusion and is expected to land with Linux 7.3, whose merge window opens after the Linux 7.2 release. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What power savings does Linux 7.3 bring for Apple M1 Pro Max Ultra SoCs? Linux 7.3 delivers approximately 1 Watt power savings for Apple M1 Pro, Max, and Ultra SoCs during suspend-to-idle (s2idle). The savings come from the new apple-pmgr-misc driver, which tweaks global power states including fabric and memory controller power states. The driver was originally written by Asahi Linux founder Hector Martin and is now making its way into the mainline kernel. _Developers running Linux on Apple Silicon can track kernel power management progress like this on daily.dev._ ## Similar posts on daily.dev - [Linux 7.3 Deprecates Many Older 32-bit ARM Platforms, Orphans Hundreds Of Drivers](https://daily.dev/posts/linux-7-3-deprecates-many-older-32-bit-arm-platforms-orphans-hundreds-of-drivers-zdj3lo0he) · Phoronix · 0 upvotes · 0 comments - [Initial Apple M3 Pro / Max / Ultra Support Being Upstreamed For Linux 7.3](https://daily.dev/posts/initial-apple-m3-pro-max-ultra-support-being-upstreamed-for-linux-7-3-by8boyrme) · Phoronix · 0 upvotes · 0 comments - [Progress Report: Linux 6.17](https://daily.dev/posts/progress-report-linux-6-17-f3cgpcenu) · Asahi Linux · 1 upvotes · 0 comments - [Intel & AMD Power Management Driver Improvements Ready For Linux 7.3](https://daily.dev/posts/intel-amd-power-management-driver-improvements-ready-for-linux-7-3-tb6kgzq3r) · Phoronix · 0 upvotes · 0 comments - [Let Sleeping CPUs Lie — S0ix](https://daily.dev/posts/let-sleeping-cpus-lie-s0ix-hzzzfsrxy) · Lobsters · 0 upvotes · 0 comments --- Tags: [#linux](https://daily.dev/tags/linux) [View this post on daily.dev](https://daily.dev/posts/apple-m1-series-socs-to-see-1-watt-power-savings-with-linux-7-3-eypoaq52o) ```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":"Apple M1 Series SoCs To See ~1 Watt Power Savings With Linux 7.3","url":"https://daily.dev/posts/apple-m1-series-socs-to-see-1-watt-power-savings-with-linux-7-3-eypoaq52o","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/apple-m1-series-socs-to-see-1-watt-power-savings-with-linux-7-3-eypoaq52o"},"datePublished":"2026-08-10T10:16:19.561Z","dateModified":"2026-08-10T10:16:37.745Z","description":"Linux 7.3 will bring approximately 1 Watt power savings for Apple M1 Pro, Max, and Ultra SoCs during suspend-to-idle (s2idle).
