Ngemuva kwezinyanga ezimbili zentuthuko, ILinus Torvalds yethule inguqulo ye-Linux kernel 5.3 ngawo phakathi izinguquko okuphawuleka kakhulu Ukusekelwa kwe-AMD Navi GPU kuqokonyisiwe, Amaprosesa we-Zhaoxi kanye ne-Intel Speed Select Power Management Technology nezinye eziningi.
Isimemezelo senguqulo entsha, ILinus ikhumbuze bonke abagqugquzeli abakhulu bokulawulwa komthetho ukuthuthukiswa kernel gcina isimilo esifanayo sezinto zesikhala somsebenzisi. Izinguquko ku-kernel akumele nganoma iyiphi indlela zephule izinhlelo zokusebenza esezivele zisebenza futhi ziholele ekuhlehlisweni kwezinga lomsebenzisi.
Ngasikhathi sinye, ukwephulwa kokuziphatha kungadala nje kuphela ushintsho ku-ABI, ukususwa kwamakhodi noma amaphutha aphelelwe yisikhathi, kepha futhi nomphumela ongaqondile wokusebenza ngokuthuthuka okusebenzayo.
Yini okusha in the Linux Kernel 5.3
Kwezinto ezintsha ezivelele kule nguqulo entsha yeLinux Kernel 5.3 singakuthola lokho ku- Umshayeli we-Amdgpu ungeza ukusekelwa kokuqala kwama-AMD NAVI GPUs (RX5700), okubandakanya i-Base Controller, Display Interaction Code (DCN2), GFX ne-Compute Support (GFX10), SDMA 5 (DMA0 System), Power Management, neMedia Encoders / Decoders (VCN2).
amdgpu futhi kuthuthukiswe ukwesekwa kwamakhadi weVega12 neVega20 GPU, okwengezwe amakhono angeziwe wokulawula amandla.
Kumshayeli we-DRM wamakhadi wevidiyo we-Intel wamachips we-Icelake, kuqaliswa imodi yokulungisa i-gamma entsha enezingxenye eziningi. Kungezwe amandla okukhombisa nge-DisplayPort ngefomethi ye-YCbCr4: 2: 0.
Izinsizakalo zememori nezesistimu
Ku-kernel 5.3, Kwethulwa ukwesekwa kwe-Intel Speed Select Power Management Technology, yini iyatholakala kumaseva wokukhetha anama-processor we-Intel Xeon. Lobu buchwepheshe bukuvumela ukuthi usethe ukwahlukanisa ukusebenza nokusebenza kokuhlelwa kwama-cores ahlukahlukene we-CPU, kukuvumela ukuthi ubeke phambili ukusebenza kwemisebenzi eyenziwe kuma-cores athile, udele ukusebenza kwamanye ama-cores
Ngakolunye uhlangothi kuLinux Kernel 5.3 izinqubo ezikhaleni lomsebenzisi zinamandla okulinda isikhathi esifushane ngaphandle kokusebenzisa izihibe kusetshenziswa umyalo we-umwait. Lo myalo, kanye ne-umonitor kanye nemiyalelo yokuphumula, izonikezwa kuma-chips "Intel" eTremont "alandelayo, futhi izovumela ukuqaliswa kokubambezeleka okusindisa amandla futhi okungathinti ukusebenza kweminye imicu lapho kusetshenziswa i-Hyper Threading.
Ngokwakhiwa kwe-RISC-V, ukungezwa kwamakhasi amakhulu ememori kungeziwe (amakhasi amakhulu).
Disk subsystem, I / O, kanye nezinhlelo zamafayela
Ohlelweni lwefayela le-XFS, inketho yokudlula eyakhiwe ngemicu eminingi isetshenziswa (ngokwesibonelo, lapho ubheka izilinganiso). Kungezwe ioctl BULKSTAT ne-INUMBERS entsha, enikeza ukufinyelela kwemisebenzi ebonakale kuhlelo lwesihlanu lwefomethi ye-FS, njengesikhathi sokuzalwa se-inode kanye nekhono lokusetha imingcele ye-BULKSTAT ne-INUMBERS yeqembu ngalinye le-AG (Ama-Assignment Groups) .
Ngesikhathi ukusekelwa kwesiqondisi se-voids kungezwa kohlelo lwefayela le-Ext4 (amabhulokhi angaxhumekile). Ifulegi elithi 'i' licutshungulwa ngamafayela avulekile (bhala ukuvinjelwa esimweni esisodwa uma ifulegi lisethiwe lapho ifayela selivele livulekile).
I-F2FS ingeza inketho yokunciphisa umqoqi kadoti lapho usebenza endaweni yokuhlola = imodi ekhutshaziwe.
Kungezwe amandla okusingathwa kwefayela lokushintshana ku-F2FS nge-I / O eqondile. Kubo bonke abasebenzisi, ukwesekwa kungezwe ngokulungiswa kwefayela nokwabiwa kwamabhulokhi kulawo mafayela.
Ukusebenziseka kahle nokuphepha
Ingqikithi ifaka i-hypervisor yamadivayisi we-ACRN ashumekiwe, ebhalwe ngokuzimisela komsebenzi wesikhathi sangempela nokufaneleka kokusetshenziswa ezinhlelweni ezibucayi engqondweni. I-ACRN ihlinzeka ngaphezulu okuncane, iqinisekisa ukubambezeleka okuphansi, nokuphendula okwanele lapho ixhumana nemishini.
Imodi yomsebenzisi we-Linux ingeze imodi ekuvumela ukuthi wehlise ijubane noma usheshise isikhathi endaweni ebonakalayo ye-UML ukwenza lula ukulungisa iphutha kwekhodi ehlobene nesikhathi. Ngaphezu kwalokho, start parameter added evumela ukuqala iwashi lesistimu kusuka iphuzu elithile ngefomethi ye-Epoch.
I-Netfilter yama-nftables ingeza ukusekelwa kwezindlela zokuhlunga amaphakheji asheshiswa ngehadiwe ngokusebenzisa i-Flow Block API engezwe kubashayeli. Amathebula wemithetho ephelele anezintambo zonke angathwalwa eduze kwama-adaptha enethiwekhi. Ukufakwa kwenziwa ngokubopha i-NFT_TABLE_F_HW etafuleni.
Imethadatha elula yezingqimba ze-Layer 3 ne-4, ukwamukela / ukwenqaba izenzo, ukufaniswa nge-IP kanye nezimbobo zenethiwekhi zomthumeli / zomamukeli nohlobo lwephrothokholi kuyasekelwa.
