Musi waChikumi 17, 2019, iyo inotevera yakakosha kuburitswa kweiyo DragonFly BSD inoshanda sisitimu - Release56 - yakaratidzwa. Kuburitswa kunounza kuvandudzwa kwakakosha kuVirtual Memory System, zvigadziriso kuRadeon uye TTM, uye kuvandudzwa kwekuita kuHAMMER2.
DragonFly yakaumbwa muna 2003 seforogo kubva kuFreeBSD vhezheni 4. Pakati peakawanda maficha eiyi imba yekuvhiya, zvinotevera zvinogona kuratidzwa:
-
Yepamusoro-inoshanda faira system HAMMER2 - tsigiro yekunyora kune akawanda snapshots akafanana, inoshanduka quota system (inosanganisira madhairekitori), inowedzera girazi, kudzvanya kwakavakirwa pane akasiyana algorithms, akagovera akawanda-master mirroring. A clustering mechanism iri pasi pekugadzirwa.
-
Iyo hybrid kernel yakavakirwa pahuremu shinda ine kugona kumhanya akawanda makopi ekernel semushandisi-nzvimbo maitiro.
Kuchinja Kukuru Kuburitswa
-
Shanduko dzakawanda dzakaitwa kune chaiyo memory subsystem, iyo yakawedzera zvakanyanya kuita, kusvika 40-70% pane mamwe marudzi ekushanda.
-
Dzakawanda shanduko kumutyairi we DRM weRadeon uye iyo TTM vhidhiyo yekurangarira manejimendi subsystem ye AMD vhidhiyo machipi.
-
Kuvandudzwa kwekuita kweHAMMER2 faira system.
-
Yakawedzera rutsigiro rweFUSE munzvimbo yemushandisi.
-
Yakaitwa yekuzviparadzanisa nedata muCPU pakati peiyo sisitimu nemushandisi: SMAP (Supervisor Mode Access Prevention) uye SMEP (Supervisor Mode Execution Prevention). Kuti uzvishandise, rutsigiro kubva kuCPU runodiwa.
-
Kune Intel processors, dziviriro kubva kuMDS (Microarchitectural Data Sampling) kirasi yekurwiswa inoitwa. Yakavharwa nekusarudzika uye inofanirwa kugoneswa nemaoko. Kudzivirirwa kweSpecter kunogoneswa nekusarudzika.
-
Kutamira kuLibreSSL kunoenderera mberi.
-
Shanduro dzakagadziridzwa dzechitatu-bato OS zvikamu.
