Release av verktyget auto-cpufreq 3.0.0 som \u00e4r avsett f\u00f6r automatisk optimering av CPU-hastighet och energif\u00f6rbrukning i systemet. Verktyget \u00f6vervakar batteriets status, CPU-belastning, CPU-temperatur och aktivitet i systemet, och aktiverar dynamiskt energisparl\u00e4ge eller h\u00f6gpresterande l\u00e4gen beroende p\u00e5 situation och valda alternativ. St\u00f6d f\u00f6r enheter med Intel-, AMD- och ARM-processorer. Grafikgr\u00e4nssnittet som anv\u00e4nder GTK eller ett kommandoradsverktyg kan anv\u00e4ndas f\u00f6r att styra. Koden \u00e4r skriven i Python och distribueras under LGPLv3-licensen. <\/p>\n

Bland de st\u00f6dda funktionerna: \u00f6vervakning av CPU-frekvens, belastning och temperatur, justering av CPU-frekvens och energif\u00f6rbrukningsl\u00e4gen beroende p\u00e5 batteriladdning, temperatur och systembelastning, automatisk optimering av CPU-prestanda och energif\u00f6rbrukning. Auto-cpufreq kan anv\u00e4ndas f\u00f6r att automatiskt f\u00f6rl\u00e4nga batteritiden f\u00f6r laptops utan att st\u00e4ndigt begr\u00e4nsa n\u00e5gra funktioner. Till skillnad fr\u00e5n verktyget TLP till\u00e5ter auto-cpufreq inte bara att st\u00e4lla in energisparl\u00e4gen under enhetens drift utan ocks\u00e5 att tempor\u00e4rt aktivera l\u00e4ge f\u00f6r h\u00f6g prestanda<\/a> (turbo boost) vid identifiering av \u00f6kad systembelastning. <\/p>\n

I den nya versionen har m\u00f6jligheten att tvinga p\u00e5 eller av turbol\u00e4ge f\u00f6r CPU (turbo boost) implementerats via grafiskt gr\u00e4nssnitt och kommandoraden (\u00abauto-cpufreq \u2014turbo={never|always|auto}\u00bb), oberoende av batteriniv\u00e5. Dessutom har parametern battery_device lagts till i konfigurationsfilen f\u00f6r att v\u00e4lja batteri vid felaktig automatisk identifiering av standardbatteriet (tillg\u00e4ngliga batterier kan ses i katalogen \/sys\/class\/power_supply\/). Ett exempel p\u00e5 konfigurationsfil f\u00f6r Nixos har lagts till.

\"Utgivning<\/center> <\/p>\n

Dessutom kan man n\u00e4mna utgivningen av verktyget TLP 1.9.1, som syftar till automatisk optimering av energif\u00f6rbrukning och f\u00f6rl\u00e4ngning av batteritiden f\u00f6r laptops. F\u00f6rutom att hantera energisparl\u00e4gen f\u00f6r CPU st\u00f6der verktyget adaptiv aktivering och deaktivering av Bluetooth, NFC och Wi-Fi. Koden f\u00f6r projektet \u00e4r skriven i Shell och Python och distribueras under GPLv2-licensen. <\/p>\n

Version 1.9 \u00e4r anm\u00e4rkningsv\u00e4rd f\u00f6r att den l\u00e4gger till den valfria bakgrundsprocessen tlp-pd, som m\u00f6jligg\u00f6r v\u00e4xling mellan tre str\u00f6ml\u00e4gesprofiler \u2014 performance, balanced och power-saver. Bakgrundsprocessen kan anv\u00e4ndas som en ers\u00e4ttning f\u00f6r tj\u00e4nsten power-profiles-daemon och st\u00f6der D-Bus API, som anv\u00e4nds f\u00f6r att v\u00e4xla profiler i GNOME, KDE och Cinnamon. Dessutom ing\u00e5r verktyget tlpctl f\u00f6r att v\u00e4xla profiler fr\u00e5n kommandoraden och starta specifika applikationer med angiven profil. <\/p>\n

I den nyligen utgivna korrigeringsversionen TLP 1.9.1 har en s\u00e5rbarhet (CVE-2025-67859) \u00e5tg\u00e4rdats i den nya bakgrundsprocessen tlp-pd, vilket g\u00f6r det m\u00f6jligt att kringg\u00e5 autentisering i tj\u00e4nsten Polkit och utf\u00f6ra \u00e5tg\u00e4rder inom tlp-pd som kr\u00e4ver administrat\u00f6rsr\u00e4ttigheter. Processen tlp-pd k\u00f6rs med root-r\u00e4ttigheter och tar emot beg\u00e4rningar via D-Bus. Vissa beg\u00e4rningar kan skickas av alla anv\u00e4ndare med bekr\u00e4ftad lokal tillg\u00e5ng till systemet (de som har startat en grafisk session), medan vissa \u00e5tg\u00e4rder endast \u00e4r tillg\u00e4ngliga f\u00f6r administrat\u00f6ren. S\u00e5rbarheten orsakas av ett t\u00e4vlingsvillkor som g\u00f6r det m\u00f6jligt att byta ut processen efter att en beg\u00e4ran har skickats, vilket g\u00f6r att polkit kommer att tro att beg\u00e4ran skickades av administrat\u00f6ren och inte kommer att beg\u00e4ra administrat\u00f6rsl\u00f6senord.
