Intel P-State gets fixes for maximum performance value handling, performance policy mode, and HWP support for older Broadwell CPUs, while Intel Idle adds ACPI _LPI low power idle object support and avoids deep idle states during initialization. AMD P-State adds dynamic EPP with per-core granularity and sets minimum limit frequency from BIOS values. The ACPI pull request removes the acpi_driver struct and brings numerous fixes, while thermal updates add support for directed package-level thermal interrupts on Intel CPUs, letting a single core handle interrupts instead of broadcasting to all cores. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What power management changes are coming to Intel and AMD CPUs in Linux 7.3? Linux 7.3 includes Intel P-State fixes for maximum performance value handling and HWP support on Broadwell CPUs, Intel Idle driver improvements including ACPI _LPI low power idle object support, and AMD P-State updates adding dynamic EPP with per-core granularity plus BIOS-based minimum frequency limits. Thermal control updates add directed package-level thermal interrupts on Intel CPUs so one core handles interrupts instead of broadcasting to all cores. _daily.dev helps kernel developers track power management and driver changes across upcoming Linux releases._ ### What does directed package-level thermal interrupt support do on Intel CPUs in Linux 7.3? It allows a single CPU core to handle package-level thermal interrupts instead of broadcasting the interrupt to every core, reducing unnecessary interrupt overhead across the system. This thermal control improvement is part of the updates submitted by Rafael Wysocki for the Linux 7.3 merge window. _engineers tuning CPU thermal behavior can follow kernel driver changes like this on daily.dev._ ## Similar posts on daily.dev - [AMD Ready With CPPC Performance Priority & Dynamic/Raw EPP In Linux 7.1](https://daily.dev/posts/amd-ready-with-cppc-performance-priority-dynamic-raw-epp-in-linux-7-1-33tkyzzmr) · Phoronix · 0 upvotes · 0 comments - [AMD P-State Driver Introducing New Features With Linux 7.1](https://daily.dev/posts/amd-p-state-driver-introducing-new-features-with-linux-7-1-llg2zq9sz) · Phoronix · 0 upvotes · 0 comments - [AMD Ryzen AI & Intel NPU Drivers Adding New Power Features With Linux 7.2](https://daily.dev/posts/amd-ryzen-ai-intel-npu-drivers-adding-new-power-features-with-linux-7-2-y9ser6ugr) · Phoronix · 0 upvotes · 0 comments - [Linux 7.2 Power Management Adds New Hardware Support While Dropping AMD Elan](https://daily.dev/posts/linux-7-2-power-management-adds-new-hardware-support-while-dropping-amd-elan-5r3mwehlj) · Phoronix · 0 upvotes · 0 comments - [Linux 7.3 To Allow Tuning AMD P-State Dynamic EPP With Per CPU Core Granularity](https://daily.dev/posts/linux-7-3-to-allow-tuning-amd-p-state-dynamic-epp-with-per-cpu-core-granularity-5oybrvdml) · Phoronix · 0 upvotes · 0 comments --- Tags: [#linux](https://daily.dev/tags/linux), [#intel](https://daily.dev/tags/intel), [#amd](https://daily.dev/tags/amd) [View this post on daily.dev](https://daily.dev/posts/intel-amd-power-management-driver-improvements-ready-for-linux-7-3-tb6kgzq3r) ```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":"Intel & AMD Power Management Driver Improvements Ready For Linux 7.3","url":"https://daily.dev/posts/intel-amd-power-management-driver-improvements-ready-for-linux-7-3-tb6kgzq3r","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/intel-amd-power-management-driver-improvements-ready-for-linux-7-3-tb6kgzq3r"},"datePublished":"2026-08-17T12:23:41.075Z","dateModified":"2026-08-17T12:24:05.254Z","description":"Linux 7.3 pulls in a batch of power management, ACPI, and thermal control updates submitted by kernel maintainer Rafael Wysocki.
