Emva kweenyanga ezimbini zophuhliso, I-Linus Torvalds yazisa i-Linux kernel version 5.3 apho phakathi Utshintsho ephawuleka kakhulu Inkxaso ye-AMD Navi GPU ibonakalisiwe, Iiprosesa zeZhaoxi kunye ne-Intel Speed Khetha iTekhnoloji yoLawulo lwaMandla nezinye ezininzi.
Isibhengezo senguqulelo entsha, ILinus ikhumbuze bonke abaxhasi abaphambili bommiselo Uphuhliso lwekernel gcina isimilo esifanayo kumacandelo esithuba somsebenzisi. Utshintsho kwi-kernel akufuneki nangayiphi na indlela lwaphule usetyenziso esele lusebenza kwaye lukhokelele ekuhlehleni kwinqanaba lomsebenzisi.
Kwangelo xesha, ukwaphulwa kwendlela yokuziphatha kunokubangela kungekuphela utshintsho kwi-ABI, ukususwa kweekhowudi eziphelelwe lixesha okanye iimpazamo, kodwa kunye nefuthe elingangqalanga lokusebenza ngokufanelekileyo.
Yintoni eNtsha kwiLinux Kernel 5.3
Kwizinto ezintsha ezinokuvela kule nguqulo intsha yeLinux Kernel 5.3 sinokuyifumana Umqhubi we-Amdgpu wongeza inkxaso yokuqala ye-AMD NAVI GPUs (RX5700), ebandakanya uLawulo lweSiseko, iKhowudi yokuNxibelelana yokubonisa (DCN2), i-GFX kunye neNkxaso yeCompute (GFX10), i-SDMA 5 (Inkqubo ye-DMA0), uLawulo lwaMandla, kunye neMultimedia Encoders / Decoders (VCN2).
Uxolo ikwaphucule nenkxaso yamakhadi eVega12 kunye neVega20 GPU, apho ukongezwa kwememori kunye namandla olawulo lwamandla.
Kumqhubi we-DRM kumakhadi evidiyo e-Intel e-Icelake chips, imo yokulungiswa kwe-gamma yamacandelo amaninzi iyaphunyezwa. Yongeze amandla okubonisa ngeDisplayPort kwifomathi yeYCbCr4: 2: 0.
Imemori kunye neenkonzo zenkqubo
Kwikernel 5.3, Ukuzisa inkxaso kwi-Intel Speed Select Management Technology, Yintoni i iyafumaneka kwiiseva ezikhethiweyo ezinee-processor ze-Intel Xeon. Obu buchwephesha bukuvumela ukuba usete ukwahlulahlulahlula ukusebenza kunye noseto lwentsebenzo lwee-cores ezahlukeneyo ze-CPU, ekuvumela ukuba ubeke phambili ukusebenza kwemisebenzi eyenziweyo kwii-cores ezithile, ukuncama ukusebenza kwezinye ii-cores
Kwelinye icala kwiLinux Kernel 5.3 Iinkqubo kwindawo yomsebenzisi zinakho ukulinda ixesha elifutshane ngaphandle kokusebenzisa ii-loops usebenzisa umyalelo omiselweyo. Lo myalelo, kunye ne-umonitor kunye nemiyalelo yokuphumla, iya kunikwa kwiitshipsi ezizayo ze-Intel "Tremont", kwaye iya kuvumela ukwenziwa kolibaziseko olonga amandla kwaye aluchaphazeli ukusebenza kweminye imisonto xa usebenzisa iHyper Threading.
Kuyilo lwe-RISC-V, inkxaso kumaphepha ememori amakhulu yongezwa (amaphepha amakhulu).
Disk subsystem, I / O, kunye neefayile zenkqubo
Kwinkqubo yefayile ye-XFS, ukhetho oluninzi olunemisonto emininzi yokuphunyezwa luyenziwa (umzekelo, xa ujonga izabelo). Ioctl BULKSTAT kunye neINUMBERS ezintsha zongezwa, zibonelela ngokufikelela kwimisebenzi ebonakala kuhlelo lwesihlanu lwefomathi ye-FS, njengexesha lokuzalwa lokungena kunye nokukwazi ukuseta iiparameter ze-BULKSTAT kunye ne-INUMBERS kwiqela ngalinye le-AG (Amaqela eSabelo).
Ngexesha Inkxaso ye-voids yolawulo yongezwa kwinkqubo yefayile ye-Ext4 (iibhloko ezingadityaniswanga). Iflegi 'i' yacutshungulwa ngeefayile ezivulekileyo (bhala isibhengezo kwimeko enye ukuba iflegi ibicwangcisiwe xa ifayile sele ivulekile).
I-F2FS yongeza ukhetho ekunciphiseni umqokeleli wenkunkuma xa usebenza kwindawo yokujonga = imowudi yokukhubazeka.
Yongeze amandla okusingatha ifayile eguqulwayo kwiF2FS ngokuthe ngqo kwi-I / O. Kubo bonke abasebenzisi, inkxaso yongezwa ukulungisa ifayile kunye nokwabiwa kweebhloko zezo fayile.
Ubuchule kunye nokhuseleko
Isiseko siquka i-hypervisor yezixhobo ze-ACRN ezifakiwe, ebhalwe ukulungela umsebenzi wexesha lokwenyani engqondweni kunye nokufaneleka kokusetyenziswa kweenkqubo ezinobunzima. I-ACRN ibonelela ngentloko encinci, iqinisekisa ukubambezeleka okuphantsi, kunye nokuphendula okwaneleyo xa unxibelelana nezixhobo.
Imowudi yomsebenzisi weLinux yongeze imo yokunciphisa okanye ukukhawulezisa ixesha kwimeko ebonakalayo ye-UML ukwenza lula ukulungisa ikhowudi enxulumene nexesha. Ukongeza, ukuqala iparameter yongezwa evumela ukuqala ikloko yenkqubo ukusuka kwindawo ethile kwifomathi ye-Epoch.
I-Netfilter yee-nftables yongeza inkxaso kwiindlela zokucoca izixhobo ezikhawulezayo zehardware ezisebenzisa i-Flow Block API eyongezwe kubaqhubi. Gqibezela iitafile zomgaqo ngayo yonke imitya enokuqhutywa ecaleni kweeadaptha zenethiwekhi. Ukubandakanywa kwenziwa ngokubopha i-NFT_TABLE_F_HW kwitafile.
Imethadatha elula yoLuhlu lwe-3 kunye ne-4 yeeprotokholi, yamkela / yala isenzo, ehambelana ne-IP kunye nomthumeli / umamkeli amazibuko wenethiwekhi kunye nohlobo lwenkqubo ziyaxhaswa.
