Mushure memwedzi miviri yekuvandudza, Linus Torvalds yakaunza Linux kernel vhezheni 5.3 nawo pakati shanduko chinonyanya kuzivikanwa AMD Navi GPU rutsigiro rwasimbiswa, Zhaoxi processor uye Intel Speed Sarudza Power Management Technology uye zvimwe zvakawanda.
Kuziviswa kweshanduro nyowani, Linus yakayeuchidza vese vanokurudzira zvikuru mutemo kernel kukura chengetedza maitiro akafanana emushandisi nzvimbo yezvinhu. Shanduko kune kernel haifanire kumbokanganisa mashandisiro ayo atove kumhanya uye anotungamira kune ekudzoka-chikamu chikamu.
Panguva imwecheteyo, kutyora maitiro kunogona kukonzera kwete chete shanduko muABI, kubviswa kwemakodhi echinyakare kana zvikanganiso, asi zvakare zvisina kunangana mhedzisiro yekushanda nemazvo zvinobatsira.
Chii Chitsva muLinux Kernel 5.3
Pamitambo mitsva inomira mushanduro iyi nyowani yeLinux Kernel 5.3 tinogona kuiwana iyo ye Amdgpu mutyairi anowedzera rutsigiro rwekutanga rwe AMD NAVI GPUs (RX5700), iyo inosanganisira Base Controller, Ratidza Kutaurirana Kodhi (DCN2), GFX uye Compute Rutsigiro (GFX10), SDMA 5 (DMA0 System), Power Management, uye Media Encoders / Decoders (VCN2).
amdgpu yakagadziridzawo rutsigiro rweVega12 uye Vega20 GPU makadhi, iyo yekuwedzera ndangariro uye masimba ekugona masimba akawedzerwa.
Mune iyo DRM mutyairi weIntel vhidhiyo makadhi eIcelake machipisi, nyowani yakawanda-chidimbu gamma yekugadzirisa modhi inoitwa. Wakawedzera kugona kuratidza kuburikidza neDisplayPort muYCbCr4: 2: 0 fomati.
Ndangariro uye system masevhisi
Mune tsanga 5.3, Kuunza rutsigiro rweIntel Speed Sarudza Power Management Technology, chii inowanikwa pane sarudza maseva ane Intel Xeon processor. Iyi tekinoroji inokutendera iwe kumisikidza partition mashandiro uye mashandiro ekuita eakasiyana CPU macores, achikubvumidza iwe kukoshesa kuita kwemabasa anoitwa pane chaiwo macores, kubayira kuita kune mamwe macores
Kune rimwe divi muLinux Kernel 5.3 Maitiro munzvimbo yemushandisi ane mukana wekumirira kwenguva pfupi pasina kushandisa zvishwe uchishandisa rairo yekumwait. Uyu kuraira, pamwe neiyo umonitor uye mira yekumira, inozopihwa pane iri kuuya Intel "Tremont" machipisi, uye inobvumidza kuitiswa kwekunonoka kunoponesa simba uye kusakanganisa mashandiro eimwe tambo kana uchishandisa Hyper Threading.
Kune iyo RISC-V yekuvakisa, tsigiro yemahombe ekurangarira mapeji akawedzerwa (makuru mapeji).
Disk subsystem, I / O, uye mafaera masystem
Zve XFS faira system, yakawanda-yakamisikidzwa inode yekudarika sarudzo inoitwa (semuenzaniso, kana uchitarisa zviga). Nyowani ioctl BULKSTAT uye INUMBERS yakawedzerwa, ichipa mukana kumabasa akaonekwa muchikamu chechishanu cheFS fomati, senge inode nguva yekuzvarwa uye kugona kumisikidza iyo BULKSTAT uye INUMBERS paramende yeboka rega rega reAG (Assignment Groups).
Nguva tsigiro yedhairekitori voids inowedzerwa yeiyo Ext4 faira system (isina kubviswa mabhuroko). Mureza 'ini' waigadzirirwa mafaira akavhurwa (nyora kurambidzwa mune imwechete mamiriro kana mureza wakaiswa apo faira rakanga ratovhurwa).
F2FS inowedzera imwe sarudzo yekudzora marara muunganidzi kana uchishanda munzvimbo yekutarisa = yakaremara modhi.
Wakawedzera kugona kwekupinda swap faira paF2FS yakananga I / O. Kune vese vashandisi, rutsigiro rwakawedzerwa kugadzirisa faira uye kugovera mabhureki kune iwo mafaera.
Virtualization uye chengetedzo
Iyo yepakati inosanganisira iyo hypervisor yezvakadzika midzi ACRN zvishandiso, iyo yakanyorwa ine chaiyo-nguva basa kugadzirira mupfungwa uye kukodzera kwekushandisa mune yakakosha masisitimu. ACRN inopa mashoma kumusoro, inoona yakaderera latency, uye kukwana kwakakwana pakupindura kana uchibatana nemidziyo.
Linux mushandisi modhi yakawedzera modhi iyo inobvumidza iwe kudzora kana kumhanyisa nguva mune chaiyo UML nharaunda kuti kurerutsa kugadzirisa kwekodhi inoenderana nenguva. Uyezve, start paramende yakawedzerwa iyo inobvumidza kutanga iyo wachi wachi kubva kune yakatarwa poindi muEpoch fomati.
Netfilter yezvisingaiti inowedzera rutsigiro rwekusefa nzira Hardware inomhanyisa mapakeji uchishandisa iyo Flow Block API yakawedzerwa kune madhiraivha. Yakazara matafura ematare netambo dzese dzinogona kutakurwa padhuze neadapter network. Kuisirwa kunoitwa nekusunga NFT_TABLE_F_HW patafura.
Rakareruka metadata yeiyo Layer 3 uye 4 protocols, gamuchira / ramba zviito, mechi ne IP uye mutumiri / mugashiri network mapoti uye protocol mhando inotsigirwa.
