Ngemuva kwezinyanga ezimbili zentuthuko, ILinus Torvalds iveze ukukhishwa kweLinux kernel 5.14 nakule nguqulo entsha yezinguquko eziphawuleka kakhulu, isibonelo new izingcingo zohlelo lwe-quotactl_fd () kanye ne-memfd_secret (), isusa ama-ide kanye nabashayeli abaluhlaza, okusha Umshayeli ophambili we-I / O weqembu, Imodi yokuhlelwa kwemisebenzi ye-SCHED_CORE, ingqalasizinda yokwakha izilawuli zohlelo eziqinisekisiwe ze-BPF.
Uhlobo olusha luthole ukulungiswa okungu-15883 konjiniyela Usayizi wama-patch ka-2002: 69MB (izinguquko zithinte amafayela ayi-12,580, Kwengezwe imigqa yekhodi engu-861501, kwasuswa imigqa engama-321,654).
Izici ezintsha eziyinhloko zeLinux 5.14
Kule nguqulo entsha a umshayeli omusha wokubeka phambili we-I / O weqembu -rq-qos, engakwazi lawula okubalulekile kokucubungula izicelo ukuvimba amadivayisi kukhiqizwa ngamalungu eqembu ngalinye. Ukusekelwa kwesilawuli esisha esiphambili sekungezwe kusihleli se-I / O se-mq-umnqamulajuqu.
Olunye ushintsho olubalulekile ku ext4, manje esebenzisa umyalo omusha we-EXT4_IOC_CHECKPOINT ioctl okuphoqa konke ukuthengiselana kwamajenali okusalindile kanye nama-buffers ahlobene nawo ukuthi kulandwe kudiski, kuphinde kubhale ngaphezulu indawo yokugcina esetshenziswe yiphephabhuku. Ushintsho yalungiswa njengengxenye yesinyathelo sokuvimbela ukuvuza kolwazi kumasistimu wamafayela. Futhi ukwenziwa kokusebenza kwenziwe kuma-Btrfs ngokususa ukubhalwa kwezimpawu ezinwetshiwe ezingadingekile ngesikhathi sokwenziwa kwe-fsync, ukusebenza kwemisebenzi ejulile enezimpawu ezinwetshiwe kukhuphuke kwaya ku-17%.
Ngakolunye uhlangothi ingeze ikholi yohlelo ye-quotactl_fd (), ekuvumela ukuthi uphathe izilinganiso hhayi ngefayela ledivayisi ekhethekile, kepha ngokuchaza isichasisi sefayela elihlotshaniswa nohlelo lwefayela lapho i-quota isetshenziselwe khona.
Futhi abashayeli abadala bamadivayisi we-block ane-interface ye-IDE basusiwe ku-kernel, osekuyisikhathi eside zithathelwe indawo yisisekelo se-libata. Ukusekelwa kwamadivayisi amadala kugcinwa ngokuphelele, izinguquko zibhekisa kuphela ethubeni lokusebenzisa amashayeli amadala, lapho usebenzisa amadrayivu aqanjwe ngegama / i-dev / hd *, hhayi / i-dev / sd *.
Isihleli Somsebenzi sinemodi entsha yokuhlela engu-SCHED_CORE lokho ikuvumela ukuthi ulawule ukuthi yiziphi izinqubo ezingasebenza ndawonye kumgogodla we-CPU ofanayo. Inqubo ngayinye ingabelwa ikhukhi lokuhlonza elichaza ubukhulu bokwethenjwa phakathi kwezinqubo (ngokwesibonelo, ezomsebenzisi ofanayo noma isitsha).
Ikholi yohlelo memfd_secret () ingeziwe, ukuthi ikuvumela ukuthi wakhe indawo yememori yangasese esikhaleni sekheli ihlukanisiwe, ibonakala kuphela kunqubo yokuphathelene, engakhonjiswa kwezinye izinqubo, futhi engafinyeleleki ngqo ku-kernel.
Isiphathimandla I-KVM yezinhlelo ze-ARM64 ingeze amandla wokusebenzisa isandiso se-MTE ezinhlelweni zezivakashi, okuvumela ukuthi ubophele amathegi ekusebenzeni kokunikezwa kwememori ngakunye futhi uhlele ukuqinisekiswa ukusetshenziswa okufanele kwezikhombi ukuvimba ukuxhashazwa kobungozi kubangelwe ukufinyelela kumabhulokhi enkumbulo asekhululiwe kakade, ukugcwala kwebhafa, izingcingo ngaphambi kokuqalisa, nokusebenzisa ngaphandle komongo wamanje.
Ukuqinisekiswa kwesikhombi kuhlinzekwe yi-ARM64 manje ingalungiselelwa ngokuhlukile isikhala se-kernel nesomsebenzisi. Ubuchwepheshe buvumela ukusetshenziswa kwemiyalo ekhethekile ye-ARM64 ukuqinisekisa amakheli okubuyisa kusetshenziswa amasiginesha edijithali, agcinwa ezingxenyeni ezingasetshenzisiwe zesikhombi uqobo.
Okwe-Intel CPUs, kuqala ngomndeni waseSkylake bese uphetha ngeCofi Lake, usebenzisa i-Intel TSX (Izandiso Zokuvumelanisa Okwenziwayo) ikhutshazwe ngokuzenzakalela, Lokhu kunikeza izindlela zokwenza ngcono ukusebenza kwezicelo ezifundwa ngokuqedwa ngamandla kokusebenza kokuvumelanisa okungadingekile. Izandiso zikhutshaziwe ngenxa yokuthi kungenzeka kwenzeke ukuhlaselwa kweZombieload.
Tambien qhubeka ngokuhlanganiswa kwe-MPTCP (I-MultiPath TCP), enguqulweni entsha, kwengezwe indlela yokusetha izinqubomgomo zakho ze-hash ye-IPv4 ne-IPv6, okwenza kube lula kusuka esikhaleni somsebenzisi ukuthola ukuthi yiziphi izinkambu zepakethe, kufaka phakathi ezifakiwe, ezizosetshenziswa lapho kubalwa i-hash enquma ukukhetha komzila wepakethe.
Isilawuli I-amdgpu isebenzise ukwesekwa kochungechunge olusha lwe-AMD Radeon RX 6000 yama-GPU, ithuthukiswe ngaphansi kwamagama ekhodi "Beige Goby" (Navi 24) kanye ne- "Yellow Carp", kanye nokwesekwa okuthuthukisiwe kweGPU Aldebaran (gfx90a) ne-APU Van Gogh. Kungezwe amandla okusebenza ngamapaneli amaningi e-eDP ngasikhathi sinye.
para I-APU Renoir, ukusekelwa kuyasetshenzwa ukuze kusetshenziswe amabhafa abethelwe kwimemori yevidiyo, Ngenkathi i-Radeon RX 6000 yangaphambilini (i-Navi 2x) ne-AMD GPUs, ukwesekwa kwe-Active State Power Management (ASPM) kunikwa amandla ngokuzenzakalela, obekunikwe amandla amaNavi 1x, Vega, namaPolaris GPUs phambilini.
Okweziphuphu ze-AMD, ukungezwa kwememori ebonakalayo okwabiwe kufakiwe (SVM) ngokususelwa ku-Heterogeneous Memory Management Subsystem (HMM), enika amandla amadivayisi anamayunithi awo okuphatha imemori (ama-MMUs) ukuthi asetshenziswe, angafinyelela kwimemori eyinhloko. Ngisho nangosizo lwe-HMM, ungahlela isikhala sekheli elihlangene phakathi kwe-GPU ne-CPU, lapho i-GPU ingafinyelela khona kwimemori eyinhloko yenqubo.
Kwezinye izinguquko ezigqamile:
- Ukuxhaswa kokuqala kwangezelwa ubuchwepheshe be-AMD Smart Shift, obuguqula ngamandla ukusetshenziswa kwe-CPU ne-GPU kuma-laptops ane-chipset ye-AMD nekhadi lemidwebo ukwenza ngcono ukusebenza emidlalweni, ukuhlela ividiyo, nokunikezwa kwe-3D.
- Kungezwe isilawuli sehluzo se-simpledrm sisebenzisa i-EFI-GOP noma i-VESA framebuffer enikezwe yi-UEFI firmware noma i-BIOS yokukhipha.
- Kungezwe ukusekelwa kwe-Raspberry Pi 400.
- Kuma-laptops we-Lenovo, isikhombimsebenzisi se-WMI sengeziwe ukuguqula izilungiselelo ze-BIOS nge / sys / class / firmware-attributes /.
- Usekelo olunwetshiwe lwe-USB4.
Isifinyezo esihle kakhulu sezindaba engizifundile kubhulogi beSpanishi, siphelele, siyachaza futhi sinemininingwane ngaphandle kokucindezela. Ngakho kufanele kube njalo. Ngiyabonga!
