Linux 5.19 ifika ndi zosintha zambiri za AMD ndi Intel. Mtundu wotsatira ukhoza kukhala Linux 6.0

Tili ndi kale pano mtundu watsopano wa makina ogwiritsira ntchito omwe akonzi ndi owerenga mabulogu amakonda kwambiri. Pa nthawi iyi, pambuyo 5.18 inali nthawi ya Momwe mungagwiritsire ntchito Linux yomwe Linus Torvalds yangolengeza kumene kumasulidwa kwake. Ndikanena kuti "inali nthawi yake", ndikutanthauza kuti zinali zomveka kuchita, ndipo zakhala choncho kuyambira pomwe zidayamba, koma panali kukayikira kwina ngati chotsatira chingakhale Linux 5.20 kapena kale. Linux 6.0. Koma nkhaniyi ikunena za mtundu wokhazikika waposachedwa, womwe kutulutsidwa kwawo tsopano ndi kovomerezeka.

Linux 5.19 ndiyotulutsa kwambiri. Kale pawindo lophatikiza zidatsimikiziridwa kuti pakhala zosintha zambiri, ngakhale kuchuluka kwake sikunapangitse kukula kwa kernel. Pansipa pali mndandanda ndi nkhani zopambana kwambiri, kunyamula ku Phoronix, sing'anga yapadera yomwe ikutsatira kwambiri kukula kwa Linux, pakati pa zinthu zina monga kusanthula kwake kodziwika ndi kufananitsa kwa mitundu yonse ya zida.
