I-Linux yi-kernel esimahla kakhulu efana ne-Unix kernel.Ngomnye wemizekelo ephambili yesoftware esimahla kunye nevulelekileyo.
ULinus Torvalds ubonise ukukhululwa kweLinux Kernel 6.8, efika emva kweenyanga ezimbini zophuhliso kwaye phakathi kwezona nguqu ziphawulekayo kolu kukhululwa kukongeza umqhubi we-Xe we-Intel GPUs, imowudi entsha yokukhusela izixhobo zebhloko, ukuphunyezwa kwendlela yokucwangcisa umsebenzi we-Deadline server, ukulungelelaniswa okuzenzekelayo kokudibanisa okufanayo. amaphepha enkumbulo, phakathi kwezinye izinto.
I-Linux 6.8 kernel ibonisa uthotho lophuculo olubalulekileyo olubandakanya imiba eyahlukeneyo, ukusuka ekusebenzeni kunye nokhuseleko ukuhambelana ne-hardware kunye nezakhiwo. Ukukhululwa kubandakanya ukulungiswa komphuhlisi we-15,641, kunye nobukhulu be-patch ye-44 MB. Utshintsho lugxile kakhulu kubaqhubi besixhobo kunye nohlaziyo lwekhowudi yezakhiwo zehardware.
Iimpawu ezintsha eziphambili zeLinux 6.8
Phakathi kolona phuculo luphawulekayo lolu guqulelo lutsha lwe Linux Kernel 6.8 yinkqubo esezantsi yedisk, I/O kunye neenkqubo zefayile, apho utshintsho lwenziwe ukubhloka ukubhala ngokuthe ngqo kwizixhobo zebhloko ezinyusiweyo (ngokungagqibekanga, indlela ivaliwe kwaye ifuna i BLK_DEV_WRITE_MOUNTED iparameter ukuba ixelwe xa kusenziwa), ngokunjalo inkqubo entsha ifuna ulwazi oluneenkcukacha kwiinkqubo zefayile ezinyusiweyo.
Kwi-XFS, umsebenzi uqhubekile kwisakhono sokusebenzisa i-f utilitysck ukujonga kunye nokulungisa iingxaki ezichongiweyo kwi-intanethi, ngaphandle kokuhlisa indlela yefayile, ngelixa ungaphakathi I-Ext4 ngoku isebenzisa umnxeba we-dioread_nolock kwiibhloko ezincinci ngaphezu kwephepha elinye lememori, ephucula ukusebenza ngokususa izitshixo ezingeyomfuneko.
Ngokumalunga nememori kunye neenkonzo zenkqubo, enye yezona zinto ziphawuleka kakhulu kule nguqulo entsha yi Uphuculo lwenkqubo esezantsi yeZswap, kuba ngoku unokunyanzela uthumelo lwamaphepha enkumbulo angafane asetyenziswe, ngaloo ndlela ukhulula i-RAM xa kuyimfuneko. Ukongeza, indlela entsha yazisiwe evala ukubhala umva kwisahlulelo sokutshintsha ukuba ukubhala kusilele, kuthintela ukukhutshelwa kwamaphepha asele ekwi-Zswap pool.
Olunye ulongezo olubalulekileyo yi SCHED_DEADLINE iseva, eyilelwe ukulungisa ukungasetyenziswa kakuhle kwe-CPU ngemisebenzi eqhelekileyo xa i-CPU ilawulwa yimisebenzi ephambili ephezulu, i-DAMON (i-Data Access MONitor) i-subsystem iye yaphuculwa ukuvumela ukujonga ukufikelela kwidatha kwi-RAM kunye nokulungelelanisa ngokuzenzekelayo ukusetyenziswa kwememori ngokwe-quotas ezithile. Ukuqaliswa kwenkxaso yamaphepha amakhulu eememori kunye nokulungiswa kwe-checker program ye-BPF yolunye uphuculo olubalulekileyo kwi-kernel 6.8.
Kwintsimi ye-virtualization kunye nokhuseleko, I-AppArmor iye yafudukela ekusebenziseni i-SHA-256 algorithm yokuqinisekisa umthetho, ukususwa komsebenzi we strlcpy () kwi kernel imele inyathelo eliya phambili ngokwemiqathango yokhuseleko ukusukela ukuba lo msebenzi, nangona uyilelwe ukunqanda ukuphuphuma kwebuffer, ubonakalisile ukuba utyekele kubuthathaka obuthile.
Kwintsimi ye-virtualization, i-hypervisor I-KVM yazise inkxaso ye-guest_memfd subsystem, ebonelela ngezakhono ezithile zolawulo lwememori kwiinkqubo zeendwendwe, inkxaso yemowudi ye-LAM yenziwe yasebenza kwi-Intel processors, ivumela inxalenye ye-64-bit pointer bits ukuba isetyenziswe ukugcina imetadata, umqhubi we-iaa wongezwe (IAA Compression Accelerator), leyo isebenzisa i-Intel Analytics Accelerator (IAA) i-cryptographic accelerators ukukhawulezisa ukunyanzeliswa kwedatha kunye nokunciphisa usebenzisa indlela ye-DEFLATE.
I-SELinux iye yazisa "init" SID ukuchonga iinkqubo zokuqalisa eziqhuba phambi kokuba imigaqo-nkqubo ye-SELinux isetyenziswe, ukuphucula ulawulo lomgaqo-nkqubo wokhuseleko kwinkqubo.
I-subsystem yenethiwekhi ibone uphuculo ekusebenzeni kakuhle i-caching kunye nesantya se-TCP sibulela ukuhlengahlengiswa kwezakhiwo zedatha ezisisiseko. Ukongezelela, i-subsystem ye-bpfilter isusiwe kwaye ukulungiswa kwezinga eliphantsi lenziwe ukuphucula ukusebenza.
Kwicala lezixhobo, abaqhubi abatsha baye bongezwa kwi-Intel, AMD, NVIDIA kunye nezinye iimpawu ze-GPU, kunye nenkxaso yeendidi ze-ARM64 ze-SoCs kunye nezixhobo ze-ARM. Nangona kunjalo, kubalulekile ukuqaphela ukuba inkxaso ye-ARM11 ARMv6K SMP processors iyekisiwe.
ekugqibeleni ukuba ukhona unomdla wokwazi ngakumbi ngayo, ungajonga iinkcukacha Kule khonkco ilandelayo.
