Inguqulo entsha ye-Kernel 5.19 isivele ikhishiwe futhi kule nguqulo entsha, phakathi kwezinguquko eziphawuleka kakhulu, isibonelo, i ukwesekwa kwe-LoongArch processor architecture, "BIG TCP" ukuhlanganiswa kwesichibi, "on-demand" imodi ku-fscache, ukususwa kwekhodi ukuze kusekelwe ifomethi ye-a.out, ikhono lokusebenzisa I-ZSTD yokucindezela i-firmware, isixhumi esibonakalayo sokuphatha inkumbulo esusiwe esikhaleni somsebenzisi, ukwethembeka okuthuthukisiwe nokusebenza kwejeneretha yenombolo engahleliwe, ukusekelwa kwe-Intel IFS (In-Field Scan), AMD SEV-SNP (Secure Nested Paging), Intel TDX (Trusted Domain Extensions) kanye nezandiso ze-ARM SME (Scalable Matrix Extension).
Inguqulo entsha yamukele ukulungiswa okungu-16401 kubathuthukisi abangu-2190 (inguqulo yakamuva ibe nokulungiswa okungu-16206 okuvela konjiniyela abangu-2127), usayizi wesichibi: 90 MB (izinguquko zithinte amafayela angu-13847, kwengezwe imigqa yekhodi engu-1149456, kukhishwe imigqa engu-349177).
Izindaba Eziyinhloko ze-kernel 5.19
Ezinguqukweni eziphawuleka kakhulu zale nguqulo entsha, singasho ukuthi kutholakala ukuthi lapho kuhlanganiswa ne-Clang 15, indlela yokwenza okungahleliwe iyasekelwa yesakhiwo se-kernel.
Umshini ukuvala umhlaba, okuvumela ukukhawulela ukusebenzisana kweqembu lezinqubo nendawo yangaphandle, ukwesekwa kwemithetho sekuhlinzekiwe lokho vumela lawula ukwenziwa kwemisebenzi ukuqamba kabusha ifayela.
Uhlelo olungaphansi I-IMA (Integrity Measurement Architecture), eklanyelwe ukuhlola ubuqotho bezingxenye zesistimu yokusebenza kusetshenziswa amasiginesha edijithali namahashi, ishintshiwe ukuze isebenzise imojuli ye-fs-verity yokuqinisekisa ifayela.
Kushintshwe indlela enengqondo yezenzo lapho kukhutshazwa ukufinyelela okungenalungelo kusistimu engaphansi ye-eBPF; ngaphambilini, yonke imiyalo ehlotshaniswa nekholi yesistimu ye-bpf() ivaliwe, futhi kusukela kunguqulo 5.19, ukufinyelela emiyalweni engaholeli ekudalweni kwento kwagcinwa. Ngalokhu kuziphatha, inqubo eyilungelo iyadingeka ukuze kulayishwe uhlelo lwe-BPF, kodwa izinqubo ezingenamalungelo zingahlanganyela nohlelo.
Kungeziwe ukusekelwa kokubuyela emuva koxhumo lwe-MPTCP (I-MultiPath TCP) ku-TCP ecacile, ezimeni lapho imisebenzi ethile ye-MPTCP ingakwazi ukusetshenziswa. I-MPTCP iyisandiso sephrothokholi ye-TCP ukuhlela ukusebenza koxhumano lwe-TCP ngokudiliva amaphakethe ngesikhathi esisodwa ezindleleni ezimbalwa ngokusebenzisa ukuxhumana kwenethiwekhi okuboshelwe kumakheli e-IP ahlukene. Kwengezwe i-API ukuphatha ukusakazwa kwe-MPTCP kusuka esikhaleni somsebenzisi.
Kubuye kuqhakanjiswe lokho wengeze imigqa yekhodi engaphezu kuka-420 okuhlobene nesilawuli amdgpu, okungaba yimigqa engu-400 amafayela anhlokweni akhiqizwa ngokuzenzakalela anedatha yamarejista e-ASIC kumshayeli we-AMD GPU, neminye imigqa engu-22,5K ihlinzeka ngokuqaliswa kokuqala kokusekelwa kwe-AMD SoC000. Usayizi ophelele womshayeli we-AMD GPUs udlule imigqa yekhodi eyizigidi ezi-21. Ngaphezu kwe-SoC4, umshayeli we-AMD uhlanganisa ukusekelwa kwe-SMU 21.x (Iyunithi Yokulawulwa Kwesistimu), ukusekelwa okubuyekeziwe kwe-USB-C ne-GPUVM, futhi ulungele ukusekela isizukulwane esilandelayo se-RDNA13 (RX 3) kanye ne-CDNA (umzwelo we-AMD) .
Umshayeli we-i915 (Intel) ithuthukise amandla okuphatha, Omazisi be-Intel DG2 (Arc Alchemist) GPUs asetshenziswa kumalaptop engeziwe, ukwesekwa kokuqala kwanikezwa isiteji se-Intel Raptor Lake-P (RPL-P), imininingwane ngamakhadi ehluzo e-Arctic Sound-M yengeziwe, yasetshenziswa i-ABI yezinjini zekhompyutha, yengezwe ukusekelwa kwamakhadi e-DG2 efomethi ye-Tile4, ukusekelwa kwe-DisplayPort HDR kumasistimu asekelwe ku-Haswell microarchitecture.
Isilawuli I-Nouveau ishintshele ekusebenziseni umshayeli we-drm_gem_plane_helper_prepare_fb, ezinye izakhiwo neziguquguqukayo zabelwe ngokwezibalo. Mayelana nokusetshenziswa kwamamojula we-Nouveau kernel yomthombo ovulekile we-NVIDIA, umsebenzi kuze kube manje wehliselwe ekuhlonzeni nasekususeni iziphazamisi. Ngokuzayo, kuhlelwe ukusebenzisa i-firmware ekhishwe ukuthuthukisa ukusebenza kwesilawuli.
amakhono athuthukisiwe ehlobene impendulo ekutholweni kokuhlukaniswa kwengidi ("i-split lock"), eyenzeka lapho ufinyelela idatha engalungile kumemori ngoba lapho usebenzisa umyalo we-athomu, idatha yeqa imigqa emibili yenqolobane ye-CPU enwetshiwe. Ukuphahlazeka okunjalo kuholela ekwehleni okukhulu ekusebenzeni. Uma ngaphambilini, ngokuzenzakalelayo, i-kernel ikhiphe isexwayiso esinolwazi mayelana nenqubo ebangele ukuphahlazeka, manje inqubo eyinkinga izokwehliswa futhi ukuze kulondolozwe ukusebenza kwesistimu yonke.
Kungeziwe ukwesekwa kwendlela ye-IFS (I-In-Field Scan) isetshenziswa kuma-Intel processors, okuthi ikuvumela ukuthi wenze izivivinyo zokuxilonga ze-CPU ezisezingeni eliphansi ekwazi ukubona izinkinga ezingabonwa ngezindlela ezijwayelekile ezisuselwe kumakhodi okulungisa iphutha (ECC) noma amabhithi okulingana.
Kwezinye izinguquko okuvelele kule nguqulo entsha:
- Kwengezwe umshayeli wesilawuli se-NVMe esisetshenziswa kumakhompuyutha we-Apple ngokusekelwe ku-chip ye-M1.
- yengeze ukusekelwa kokuqala kokwakhiwa kwesethi yemiyalo ye-LoongArch esetshenziswa kuma-Loongson 3 5000 processors, esebenzisa i-RISC ISA entsha efana ne-MIPS ne-RISC-V.
- I-LoongArch architecture itholakala ngezinguqulo ezintathu: 32-bit simplified (LA32R), 32-bit normal (LA32S), kanye ne-64-bit (LA64).
- Kwengezwe amandla okushumeka ifayela le-bootconfig ku-kernel.
- 'CONFIG_BOOT_CONFIG_EMBED_FILE=”/PATH/TO/BOOTCONFIG/FILE”'.
- Kususwe usekelo lwezinketho ze-x86-specific boot: nosp, nosmap, nosmep, noexec, ne-noclflush).
- Ukusekelwa kwesakhiwo esiphelelwe yisikhathi se-CPU h8300 (Renesas H8/300), esinganakekelwa isikhathi eside, kunqanyuliwe.
Okokugcina uma unentshisekelo yokwazi kabanzi ngakho mayelana nale nguqulo entsha, ungabheka imininingwane Kulesi sixhumanisi esilandelayo.
