Linus Torvalds adalengeza kukhazikika kwa mtundu wa 5.9.
Zina mwa zosintha zina, adayambitsa chithandizo cha FSGSBASE mu 5.9 kernel, yomwe ikuyenera kupititsa patsogolo kusintha kwa machitidwe pa AMD ndi Intel processors. FSGSBASE imalola zomwe zili m'marejista a FS/GS kuti ziwerengedwe ndi kusinthidwa kuchokera ku malo ogwiritsira ntchito, zomwe ziyenera kupititsa patsogolo magwiridwe antchito omwe akhudzidwa ndi zovuta za Specter/Metldown. Thandizo lokhalo linawonjezedwa ndi akatswiri a Microsoft zaka zingapo zapitazo.
Komanso:
- thandizo lowonjezera la Radeon RX 6000 "RDNA 2"
- anawonjezera thandizo la NVMe drive zoning commands (NVMe zoned namespaces (ZNS))
- thandizo loyamba la IBM Power10
- kusintha kosiyanasiyana pamakina osungirako, chitetezo chowonjezereka pakugwiritsa ntchito zigawo za GPL polumikiza madalaivala omwe ali ndi zida za kernel.
- njira yogwiritsira ntchito mphamvu (Energy Model framework) tsopano ikufotokoza osati khalidwe la kugwiritsa ntchito mphamvu kwa CPU, komanso zipangizo zotumphukira.
- Adawonjezedwa REJECT pa PREROUTING stage ku Netfilter
- kwa AMD Zen ndi mitundu yatsopano ya CPU, chithandizo chaukadaulo cha P2PDMA chawonjezedwa, chomwe chimakulolani kugwiritsa ntchito DMA kusamutsa deta mwachindunji pakati pa kukumbukira kwa zida ziwiri zolumikizidwa ndi basi ya PCI.
