Igalia engineer Tvrtko Ursulin has since posted a small two-patch fix (under 100 lines) addressing the issue reported by Luke Wildhardt, with hopes of restoring fair as the default scheduler policy in Linux 7.3. Once fair is reinstated, plans call for removing the FIFO and round-robin policies and reapplying code simplifications that had been temporarily reverted. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### Why did Linux 7.2 revert the DRM scheduler's fair policy back to FIFO? A last-minute user-reported regression caused poor performance on the Radeon RX 9070 XT when using the new fair scheduler policy, so Linux 7.2 reverted to FIFO as the default DRM scheduler policy instead. Igalia engineer Tvrtko Ursulin has since posted a two-patch fix, under one hundred lines total, aimed at resolving the regression so fair can become the default again in an upcoming kernel release, hopefully Linux 7.3. _daily.dev helps kernel contributors track fast-moving DRM scheduler fixes as they land._ ### What GPU was affected by the Linux DRM fair scheduler regression? The Radeon RX 9070 XT showed poor performance under the fair scheduler policy in Linux 7.2, which is what triggered the revert to FIFO as the default. The issue was reported by Luke Wildhardt and fixed by Igalia's Tvrtko Ursulin with two small patches, one of which was based on an AI-proposed fix suggested during the report. _Track GPU driver regressions like this one on daily.dev before they hit your kernel build._ ## Similar posts on daily.dev - [Linux 7.2 To Set Default DRM Scheduler Priority To "Fair", New AIE4 Hardware In AMDXDNA](https://daily.dev/posts/linux-7-2-to-set-default-drm-scheduler-priority-to-fair-new-aie4-hardware-in-amdxdna-s4wr5gi4n) · Phoronix · 0 upvotes · 0 comments - [Linux Fair DRM Scheduler Graduates Out Of The "RFC" Phase](https://daily.dev/posts/linux-fair-drm-scheduler-graduates-out-of-the-rfc-phase-zvxyi0sby) · Phoronix · 0 upvotes · 0 comments - [Linux 7.3 Expected To "Flatten The Pick" For Better Scheduling While Gaming & More](https://daily.dev/posts/linux-7-3-expected-to-flatten-the-pick-for-better-scheduling-while-gaming-more-4sk8p5nyz) · Phoronix · 0 upvotes · 0 comments - ["Flatten The Pick" Linux Patches Progress For Better cgroup Scheduling While Linux Gaming](https://daily.dev/posts/flatten-the-pick-linux-patches-progress-for-better-cgroup-scheduling-while-linux-gaming-hdbqr0cnv) · Phoronix · 1 upvotes · 0 comments --- Tags: [#linux](https://daily.dev/tags/linux) [View this post on daily.dev](https://daily.dev/posts/patches-posted-for-fixing-the-linux-drm-scheduler-s-fair-policy-voe2ruoqr) ```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":"Patches Posted For Fixing The Linux DRM Scheduler's Fair Policy","url":"https://daily.dev/posts/patches-posted-for-fixing-the-linux-drm-scheduler-s-fair-policy-voe2ruoqr","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/patches-posted-for-fixing-the-linux-drm-scheduler-s-fair-policy-voe2ruoqr"},"datePublished":"2026-08-14T10:10:40.655Z","dateModified":"2026-08-14T10:11:02.752Z","description":"The Linux DRM subsystem had to revert its new 'fair' GPU scheduler policy back to FIFO as the default for Linux 7.2 after a user-reported performance...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/602862f4c6ca511314267a7340e526a5?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/602862f4c6ca511314267a7340e526a5?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"Phoronix","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"Phoronix","logo":"https://media.daily.dev/image/upload/t_logo,f_auto/v1/logos/6a26ba379dd64932830aa0c9803dd7ee","url":"https://daily.dev/sources/phoronix"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/patches-posted-for-fixing-the-linux-drm-scheduler-s-fair-policy-voe2ruoqr","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"linux","timeRequired":"PT2M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Phoronix","item":"https://daily.dev/sources/phoronix"},{"@type":"ListItem","position":3,"name":"Patches Posted For Fixing The Linux DRM Scheduler's Fair Policy"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/patches-posted-for-fixing-the-linux-drm-scheduler-s-fair-policy-voe2ruoqr#faq","mainEntity":[{"@type":"Question","name":"Why did Linux 7.2 revert the DRM scheduler's fair policy back to FIFO?","acceptedAnswer":{"@type":"Answer","text":"A last-minute user-reported regression caused poor performance on the Radeon RX 9070 XT when using the new fair scheduler policy, so Linux 7.2 reverted to FIFO as the default DRM scheduler policy instead.
