Ngomhla we-17 kaJuni, ngo-2019, ukukhutshwa okubalulekileyo okulandelayo kwenkqubo yokusebenza ye-DragonFly BSD-Release56 - yaboniswa. Ukukhutshwa kuzisa ukuphuculwa okubalulekileyo kwiNkqubo yeMemori yeVirtual, uhlaziyo lweRadeon kunye ne-TTM, kunye nokuphuculwa kokusebenza kwi-HAMMER2.
I-DragonFly yasekwa ngo-2003 njengefolokhwe evela kwi-FreeBSD version yesi-4. Phakathi kwezinto ezininzi zeli gumbi lokusebenza, oku kulandelayo kunokugqanyiswa:
-
Inkqubo yefayile yokusebenza ephezulu HAMMER2 - inkxaso yokubhala kwii-snapshots ezininzi ngokufanayo, inkqubo ye-quota eguquguqukayo (kubandakanywa ne-directory), i-mirroring eyongezelelweyo, ukunyanzeliswa okusekelwe kwii-algorithms ezahlukeneyo, i-mirroring multi-master mirroring. Indlela yokudibanisa iphantsi kophuhliso.
-
I-hybrid kernel esekwe kwimisonto ekhaphukhaphu ekwaziyo ukuqhuba iikopi ezininzi zekernel njengeenkqubo zesithuba somsebenzisi.
Utshintsho oluKhulu oluKhulu
-
Utshintsho oluninzi lwenziwe kwi-memory subsystem, eye yandisa kakhulu ukusebenza, ukuya kuthi ga kwi-40-70% kwiintlobo ezithile zokusebenza.
-
Iinguqu ezininzi kumqhubi we-DRM weRadeon kunye nenkqubo yolawulo lwememori yevidiyo ye-TTM yeechips zevidiyo ze-AMD.
-
Ukusebenza okuphuculweyo kwenkqubo yefayile yeHAMMER2.
-
Inkxaso eyongeziweyo yeFUSE kwindawo yomsebenzisi.
-
Iphunyezwe ukuhlukaniswa kwedatha kwi-CPU phakathi kwenkqubo kunye nomsebenzisi: I-SMAP (uThintelo loFikelelo lweNdlela yoMphathi) kunye ne-SMEP (UThintelo lokuSebenza loMphathi). Ukuzisebenzisa, inkxaso evela kwi-CPU iyafuneka.
-
Kwiiprosesa ze-Intel, ukukhuselwa kwi-MDS (Microarchitectural Data Sampling) iklasi yokuhlaselwa iphunyeziwe. Ivaliwe ngokungagqibekanga kwaye kufuneka yenziwe ngesandla. Ukhuseleko lweSpecter luvulwa ngokungagqibekanga.
-
Ukufudukela kwiLibreSSL kuyaqhubeka.
-
Iinguqulelo ezihlaziyiweyo zamacandelo e-OS yomntu wesithathu.
