News Linux News der Woche: Ubuntu 24.10, Space Marine 2 auf Linux, AMDs 3D V-Cache

[Kaito Kariheddo]

Nicht immer lässt sich zeitnah über jede Neuigkeit rund um das freie Betriebssystem berichten, manche Ereignisse sind es aber dennoch wert, Erwähnung zu finden. In dieser Zusammenfassung überblickt die Redaktion alle wichtigen Meldungen aus der Linux-Welt der vorangegangenen Woche.

Irgendwie finde ich es ziemlich fragwürdig, wenn Entwickler sich ausschließlich auf das Deck fixieren. Glücklicherweise bietet Valve die Möglichkeit, einfach ein Deck zu "faken" - toll ist es trotzdem nicht.

Davon abgesehen finde es immer wieder faszinierend, dass immer noch so oft und so viele neue Ideen/Verbesserungen/Spezialisierungen im Bereich Scheduler und Co das Licht der Welt erblicken 👍

@Termy Die Möglichkeit die CPU-Topologie einzulesen (/proc/cpuinfo) und eine entsprechende Affinity via sched_setaffinity(2) zu setzen gibt es schon lange.

Aber lässt sich aus /proc/cpuinfo auslesen, welcher core zum 3D-Cache CCD gehört?
Ich kann das in den Angaben nicht erkennen, habe allerdings im 5800X3D auch kein zweites CCD

Gerade noch mal nachgeschaut, aus /sys/devices/system/cpu/ sollte sich das raus kratzen lassen.

Ergänzung (Gestern um 19:12)

Da ist die Info: (Ich habe aber keine asymetrischen CPUs)

Danke für die Infos. 👍🙌
