Thaum Lub Rau Hli 17, 2019, qhov kev tso tawm tseem ceeb tom ntej ntawm DragonFly BSD operating system - Tso tawm 56 - tau nthuav tawm. Qhov kev tso tawm coj cov kev txhim kho tseem ceeb rau Virtual Memory System, hloov tshiab rau Radeon thiab TTM, thiab kev txhim kho kev ua haujlwm rau HAMMER2.
DragonFly tau tsim nyob rau hauv 2003 raws li ib tug diav rawg los ntawm FreeBSD version 4. Ntawm ntau qhov nta ntawm chav ua haujlwm no, cov hauv qab no tuaj yeem raug qhia:
-
Cov ntaub ntawv ua haujlwm siab HAMMER2 - kev txhawb nqa rau kev sau ntawv rau ntau cov duab thaij duab nyob rau hauv tib lub sijhawm, qhov hloov pauv tau yooj yim (nrog rau cov ntawv teev npe), incremental mirroring, compression raws li ntau yam algorithms, faib multi-master mirroring. Ib tug clustering mechanism yog nyob rau hauv txoj kev loj hlob.
-
Lub hybrid kernel raws li cov xov sib sib zog nqus nrog lub peev xwm los khiav ntau cov ntawv luam ntawm cov ntsiav raws li cov neeg siv-chaw ua haujlwm.
Kev hloov pauv loj
-
Ntau qhov kev hloov pauv tau ua rau lub cim xeeb virtual subsystem, uas tau nce kev ua tau zoo, mus txog 40-70% ntawm qee hom kev ua haujlwm.
-
Ntau qhov kev hloov pauv rau DRM tus tsav tsheb rau Radeon thiab TTM video nco tswj subsystem rau AMD video chips.
-
Txhim kho kev ua haujlwm ntawm HAMMER2 cov ntaub ntawv kaw lus.
-
Ntxiv kev txhawb nqa rau FUSE hauv qhov chaw neeg siv.
-
Siv cov ntaub ntawv cais tawm hauv CPU ntawm lub kaw lus thiab cov neeg siv: SMAP (Tus Thawj Saib Xyuas Kev Tiv Thaiv Kev Tiv Thaiv) thiab SMEP (Tus Thawj Saib Xyuas Kev Tiv Thaiv Kev Tiv Thaiv). Txhawm rau siv lawv, kev txhawb nqa los ntawm CPU yog xav tau.
-
Rau Intel processors, tiv thaiv MDS (Microarchitectural Data Sampling) chav kawm ntawm kev tawm tsam yog siv. Nws yog neeg xiam los ntawm lub neej ntawd thiab yuav tsum tau manually enabled. Kev tiv thaiv Spectre yog qhib los ntawm lub neej ntawd.
-
Kev tsiv teb tsaws chaw mus rau LibreSSL txuas ntxiv mus.
-
Hloov tshiab versions ntawm thib peb-tog OS Cheebtsam.
