Key changes include: DVFSRC hardware communication support enabling CPU voltage and EMI bus bandwidth scaling for better power efficiency; Host Software Queue (HSQ) implementation in the MediaTek MMC/SD controller driver for SoCs lacking CQHCI hardware, yielding up to +50.5% IOPS improvement and 150ms reduction in access times during intensive I/O; OF Graph support in the MediaTek Display Controller driver to replace hardcoded display paths with device tree specifications; and modernization of the MediaTek RTC driver plus PCIe Gen3 link speed/width restriction support. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What performance improvements does Host Software Queue (HSQ) bring to MediaTek MMC/SD controllers in Linux 6.13? HSQ in Linux 6.13 reduces spinlock frequency in the MediaTek mtk-sd driver by batching multiple commands into a single operation. On a MT8195 Tomato Chromebook with a SanDisk Extreme Pro A2 MicroSD card, this yielded up to 150ms reduction in average access times during intensive I/O, +50.5% IOPS and bandwidth on random 4K reads/writes, +24.28% on random 4K reads, and +3.14% on sequential reads, largely eliminating UX micro-stuttering. _Developers working on MediaTek Chromebook or embedded Linux platforms track kernel I/O improvements like these on daily.dev._ ### Why was OF Graph support added to the MediaTek Display Controller driver in Linux 6.13? MediaTek Display Data Paths are machine-specific because the physical display outputs vary per device (Chromebook, smartphone, SBC, etc.). Hardcoding every path into the mediatek-drm driver caused unnecessary driver growth. OF Graph support lets display paths be defined in each machine's Device Tree instead, reflecting the hardware's flexibility without bloating the driver. _Engineers building display pipelines on MediaTek SoCs find kernel driver architecture discussions like this on daily.dev._ ## Similar posts on daily.dev - [Many MediaTek MT76 WiFi Driver Improvements Coming For Linux 7.1](https://daily.dev/posts/many-mediatek-mt76-wifi-driver-improvements-coming-for-linux-7-1-qqifli1rz) · Phoronix · 0 upvotes · 0 comments - [Main changes, Arm, RISC-V, and MIPS architectures](https://daily.dev/posts/main-changes-arm-risc-v-and-mips-architectures-eds3j61xx) · CNX Software · 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 - [Many USB Improvements & New Hardware Merged For Linux 7.1](https://daily.dev/posts/many-usb-improvements-new-hardware-merged-for-linux-7-1-l0wflpqfx) · Phoronix · 0 upvotes · 0 comments - [MediaTek MT7927 "Filogic 380" WiFi Support Coming Together For Linux](https://daily.dev/posts/mediatek-mt7927-filogic-380-wifi-support-coming-together-for-linux-gzkhfjene) · Phoronix · 0 upvotes · 0 comments --- Tags: [#linux](https://daily.dev/tags/linux) [View this post on daily.dev](https://daily.dev/posts/mediatek-improvements-in-linux-6-13-wtb2p30vn) ```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":"MediaTek improvements in Linux 6.13","url":"https://daily.dev/posts/mediatek-improvements-in-linux-6-13-wtb2p30vn","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/mediatek-improvements-in-linux-6-13-wtb2p30vn"},"datePublished":"2026-08-11T08:52:27.902Z","dateModified":"2026-08-11T09:02:17.285Z","description":"Linux 6.13 brings several MediaTek SoC improvements contributed by Collabora engineers.
