I-Linux Kernel
Ngemuva kwezinyanga ezimbili zentuthuko, U-Linus Torvalds umemezele ukukhululwa kwe-Linux 6.0 kernel, esimemezelweni, ukubhalwa kabusha kwezinombolo kwenziwa ngenxa yezizathu zobuhle futhi kuyisinyathelo esisemthethweni esidambisa ukuphazamiseka kokuqongelela izinombolo eziningi ochungechungeni, njengoba uLinus ahlekisa ngokuthi isizathu sokushintsha inombolo yenguqulo maningi amathuba okuthi iphelelwe iminwe. nezinzwane ukubala izinombolo zenguqulo.
Uhlobo olusha ithole ukulungiswa okungu-16585 kusuka konjiniyela be-2129, usayizi wesichibi ungu-103 MB (izinguquko ezithintekile amafayela angu-13939, kwengezwe imigqa yekhodi engu-1420093, kukhishwe imigqa engu-318741).
Amanoveli amakhulu we-Linux 6.0
Kule nguqulo entsha ye-Linux Kernel 6.0, I-Btrfs isebenzisa inguqulo yesibili yephrothokholi yomyalo othi "thumela"., esebenzisa ukusekelwa kwemethadatha eyengeziwe, ukuthumela idatha ngamabhulokhi amakhulu (okungaphezu kuka-64K), nokudlulisa ama-degree ngendlela ecindezelwe. Kukhuphuke kakhulu (kufika ezikhathini ezi-3) ukusebenza kokusebenza ukufunda okuqondile ngenxa yokufundwa ngasikhathi sinye kwemikhakha engafika ku-256, kugqanyiswa ukuthi ukungqubuzana kokukhiya kwehlisiwe futhi ukuqinisekiswa kwemethadatha kwasheshiswa ngokunciphisa imethadatha ebekelwe izici ezivilaphayo.
Olunye ushintsho olubalulekile oluhlobene nezinhlelo zamafayela ukuthi imisebenzi emisha yengeziwe EXT4_IOC_GETFSUUID kanye ne-EXT4_IC_SETFSUUID ioctl ohlelweni lwamafayela e-ext4 ukuze ubuyise noma usethe i-UUID egcinwe ku-superblock, kanye nesistimu yefayela ye-F2FS inikeza imodi yememori ephansi eyenza ukusebenza kahle kumadivayisi e-RAM aphansi futhi ikuvumela ukuthi wehlise ukusetshenziswa kwememori kuya ezindlekweni zokusebenza.
Kuma-Overlayfs, uma ekhwezwe phezu kwesistimu yefayela enemephu ye-ID yomsebenzisi, izinhlu zokulawula ukufinyelela ezithobelana ne-POSIX zisekelwa ngendlela efanele.
Enye into entsha eyethulwa yiLinux 6.0 yile imisebenzi emisha kusistimu engaphansi ye-DAMON (I-Data Access Monitor) lokho Abavumeli kuphela ukuqapha ukufinyelela kwezinqubo ku-RAM kusuka endaweni yomsebenzisi, kodwa futhi kunomthelela ekuphathweni kwenkumbulo. Ikakhulukazi, kuhlongozwa imojuli entsha ye-"LRU_SORT", evumela uhlu lwe-LRU (Olusanda Kusetshenziswa Kamuva) ukuthi luhlelwe kabusha ukuze kwandiswe ukubaluleka kwamakhasi athile enkumbulo.
Kusetshenziswe ikhono lokudala izifunda zenkumbulo ezintsha kusetshenziswa amakhono ebhasi le-CXL (Compute Express Link), elisetshenziselwa ukuhlela ukusebenzisana kwesivinini esikhulu phakathi kwe-CPU namadivayisi enkumbulo. I-CXL ivumela ukuxhuma nokusebenzisa izifunda ezintsha kusuka enkumbulweni ihlinzekwa ngamadivaysi ememori angaphandle njengezinsiza zesikhala sekheli lendawo eyengeziwe ukuze kunwetshwe imemori yokufinyelela engahleliwe yesistimu (DDR) noma inkumbulo yokufunda kuphela (PMEM).
Kulungiswe izinkinga zokusebenza kwesistimu kuma-AMD Zen processors okubangelwa ikhodi engezwe eminyakeni engu-20 edlule ukulungisa inkinga yezingxenyekazi zekhompuyutha kwamanye ama-chipset (umyalelo we-WAIT owengeziwe wengeziwe ukuze ubambezele iphrosesa ukuze i-chipset ibe nesikhathi sokungena esimweni sokungenzi lutho). Ushintsho lubangele ukwehla kokusebenza kuwo wonke umthwalo okuvame ukushintshana phakathi kwezimo ezingenzi lutho nezimatasa. Isibonelo, ngemva kokukhubaza ukuqondisa kokudlula, izikolo ezimaphakathi zokuhlolwa kwe-tbench zikhuphuke zisuka ku-32191 MB/s zaya ku-33805 MB/s.
Ukusabalalisa komsebenzi okuthuthukisiwe phakathi kwama-CPU cores ezinhlelweni ezinkulu, okwenza kube nokwenzeka ukwandisa ukusebenza ngaphansi kwezinhlobo ezithile zomthwalo.
A Ifulegi elisha le-IORING_RECV_MULTISHOT kusixhumi esibonakalayo se-I/O esingavumelanisi io_uring, ekuvumela ukuthi usebenzise imodi yokushutha okuningi ngekholi yesistimu ye-recv() ukwenza ukufunda okuningi kusokhethi efanayo yenethiwekhi ngesikhathi esisodwa. I-io_uring iphinde isebenzise ukwesekwa kokudluliselwa kwenethiwekhi ngaphandle kokubhafa okuphakathi-
Kukhishwe isixhumi esibonakalayo se-"efivars" esihoxisiwe kuma-sysfs ukufinyelela okuguquguqukayo kwe-UEFI boot (ukufinyelela idatha ye-EFI, isistimu yefayela ebonakalayo ye-efivarfs isisetshenziswa kabanzi).
SIndlela yokuqinisekisa i-RV yengeziwe (Ukuqinisekiswa kwesikhathi sokusebenza) ukuqinisekisa ukusebenza okulungile kumasistimu athembeke kakhulu okuqinisekisa ukuthi awekho amaphutha. Ukuqinisekisa kwenziwa ngesikhathi sokusebenza ngokunamathisela izibambi kumaphoyinti okulandela umkhondo ahlola ukuqhubeka kwangempela kokwenziwa kuqhathaniswa nemodeli ye-automaton yereferensi ezenzakalelayo echaza ukuziphatha okulindelekile kwesistimu. Phakathi kwezinzuzo ye-VR yiyona ikhono lokunikeza ukuqinisekiswa okuqinile ngaphandle kokuqaliswa okuhlukile kwalo lonke uhlelo ngolimi lokumodela, kanye nokusabela okuguquguqukayo ezenzakalweni ezingalindelekile.
Okunye okugqanyisiwe kukhona izingxenye ze-kernel ezihlanganisiwe zokuphathwa kwe-enclave ngokusekelwe kubuchwepheshe be-Intel SGX2 (I-Software Guard eXtensions), evumela izinhlelo zokusebenza ukuthi zisebenzise ikhodi ezindaweni ezihlukanisiwe zememori ezibethelwe, ukufinyelela kuzo okukhawulelwe lonke uhlelo.

Okokugcina Uma unesifiso sokwazi okwengeziwe ngakho, ungabheka imininingwane kufayela le- isixhumanisi esilandelayo.
