I-Linux iyi-kernel yamahhala kakhulu efana ne-Unix kernel. Ingenye yezibonelo eziyinhloko zesofthiwe yomthombo ovulekile nokhululekile.
Ngemuva kwezinyanga ezimbili zentuthuko, U-Linus Torvalds umemezele ukukhululwa kwe-Linux kernel 6.5. Izinguquko eziphawulekayo zihlanganisa: ukusekelwa kwendlela yokuphatha amandla ye-Intel TPMI, ikholi yesistimu ye-cachestat, ukuhlanganiswa okuqhubekayo kokusekelwa kolimi lwe-Rust, ukusekelwa kwemiyalelo ye-RISC-V vector, nokuningi.
Kule nguqulo entsha ye-Linux 6.5 Kernel, cishe izilungiso eziyi-14674 zenziwe futhi imigqa yekhodi eyi-1294205 yengezwa.
Izici ezintsha eziyinhloko zeLinux 6.5
Kule nguqulo entsha ye-Linux 6.5 Kernel, isixhumi esibonakalayo se-RAPL yengeza ukusekelwa kwendlela ye-TPMI Isetshenziswa kuma-Intel processors ukuze kunikwe amandla izici zokuphatha amandla, lesi sikhombimsebenzisi esisha sihambisana ne-RAPL MSR/MMIO eyayitholakala ngaphambilini isixhumi esibonakalayo futhi sinikeza izilungiselelo ezivumelana nezimo zomkhawulo wamandla.
Olunye ushintsho oluvela enguqulweni entsha ukuthi ingeze i-cachestat() ikholi, elinomsebenzi wokuthintana nesimo senqolobane yekhasi samafayela nezinkomba. Ucingo olusha lwesistimu luvumela izinhlelo zendawo yomsebenzisi ukunquma ukuthi yimaphi amakhasi efayela agcinwe kumemori enkulu.
Ngokungafani nekholi yesistimu etholakala ngaphambilini i-mincore(), ikholi ye-cachestat() ikuvumela ukuthi ubuke izibalo ezinemininingwane eminingi, njengenombolo yamakhasi afakwe kunqolobane, amakhasi angcolile, amakhasi akhishiwe, amakhasi asanda kukhishwa, namakhasi amakwe ukuthi abhalwe kabusha.
Ngokwengxenye yentuthuko esaqhubeka nokusetshenziswa ekusekelweni kwe-Rust, Kuyavela ukuthi kube nokwenzeka ukusebenzisa inguqulo ye-Rust 1.68.2, ezinzisa eminye yemisebenzi esetshenziswa ku-kernel. I-API yokuqala yephinikhodi ethuthukisiwe kanye namandla anwetshiwe 'ephutha', 'ukuvumelanisa', 'str', 'umsebenzi' kanye 'nezinhlobo' zamamojula.
Okwamasistimu e-ARM64, ukusekelwa kwesandiso se-PIE sekwenziwe, okunikeza ukusebenza ukuze ulungiselele amalungelo okufinyelela kumemori. Esikhundleni solwazi lwezimvume ze-hardcoding kuthebula lekhasi lememori, i-PIE isebenzisa inkomba yohlu lwezimvume ecaciswe kusibhalisi.
Ku-io_uring, i ikhono lokugcina amabhafa endandatho nokuthumela olayini enkumbulweni inikezwe endaweni yomsebenzisi. Uhlelo lokusebenza manje selingakwazi ukwaba indawo yememori ngokuzimela futhi liyidlulisele ku-io_uring ukusizakala ngekhono lokusebenzisa amakhasi ememori amakhulu.
Ngaphezu kwalokhu, enye yezinto ezintsha ezigqamayo kule nguqulo entsha ye-Linux 6.5, imigqa yomsebenzi we-kernel, esebenzisa ukutholwa nokumaka okuzenzakalelayo kwemisebenzi ngokusetshenziswa kwe-CPU okukhulu.
Kuzinhlelo ezinamaphrosesa I-Zen 2 kanye ne-AMD entsha, umshayeli we-P-State unikwe amandla ngokuzenzakalelayo esikhundleni somshayeli we-CPUFreq wokuphathwa kwamandla, kanye nepharamitha X86_AMD_PSTATE_DEFAULT_MODE yengeziwe ukuze kukhethwe imodi ye-P-State ezenzakalelayo.
Uhlelo lwefayela I-Overlayfs, ithuthelwe ukuze isebenzise i-mount API entsha futhi kwenziwe izinguquko ukuze kuhlelwe ukusebenza kohlelo lwefayela le-ComposeFS njengokuhambisana nezinhlelo zefayela le-OverlayFS kanye ne-EROFS, kunokugcina ukuqaliswa okuhlukile. Ku-kernel 6.5, i-Composefs yengeze usekelo lwezendlalelo "zedatha kuphela" ezisetshenziselwa idatha kuphela (okuhlukile kumethadatha).
Ukulungiselelwa okusha kuphakanyiswe kusistimu yefayela ye-Btrfs, njengoba ukudluliswa kwedatha kusetshenziswe ngemodi yokuvumelanisa ukuze kusetshenziswe ama-algorithms asheshayo ukubala i-crc32c kanye ne-xxhash checksums).
Kwezinye izinguquko okugqamile:
- Umshayeli we-AMDGPU wengeze ukusekelwa kwemvamisa ye-overclocking yamakhadi wevidiyo we-Radeon RX 7000.
- Umshayeli we-i915 uletha ukusekelwa kokuqala kwama-Intel Meteor Lake chips futhi wengeza amandla okusebenzisa i-VRR kumakhompyutha aphathekayo anezibonisi ze-eDP.
- Ukusekelwa okunwetshwe ngokuphawulekayo kwezilawuli ze-USB4, okuhlanganisa ukwesekwa kokuqala kwezilawuli ze-Intel Barlow Ridge ezisekela i-USB4 v2 (80 Gbps ngaphezu kwe-USB Type-C).
- Usekelo lwamadivayisi e-MIDI 2.0 lwengezwe kusistimu engaphansi yomsindo ye-ALSA.
- Kwengezwe umshayeli wamakhonsoli emidiya e-NVIDIA SHIELD
Okokugcina uma unentshisekelo yokwazi kabanzi ngakho, ungabheka imininingwane kufayela le- isixhumanisi esilandelayo.
