Ngemuva kwezinyanga ezimbili zentuthuko, ILinus Torvalds yethule ukukhishwa kweLinux Kernel 5.0. Ngasikhathi sinye, iFree Software Foundation yaseLatin America idale inguqulo yamahhala ye-Kernel 5.0: Linux-libre 5.0-gnu.
phakathi ushintsho oluphawuleka kakhulu ku-Kernel 5.0 ukungezwa kwe-Android-based ARM enkulu.LITTLE CPU Task Scheduler, i-Adiantum file system encryption mechanism, Ukusekelwa kobuchwepheshe beFreeSync kumshayeli we-AMDGPU nokunye okuningi.
Izindaba eziyinhloko zeKernel 5.0
Phakathi kwezinguquko eziphawuleka kakhulu kuKernel 5.0 sithola ukungezwa kwendlela yokubethela yohlelo lwefayela le-Adiantum ithuthukiswe yiGoogle, engasetshenziswa kumadivayisi anamandla aphansi okuthi, ngenxa yokugcwala ngokweqile, angakwazi ukusebenzisa i-AES block encryption algorithm.
Ukuqaliswa kwe-Adiantum uthembele ekusetshenzisweni kwe-hash okusheshayo kwe-NH, i-algorithm yokufakazela ubuqiniso yomyalezo nge-Poly1305 (MAC, ne-XChaCha12 stream encryptionkanye nokusebenza okukodwa okususelwa ekubethelweni kwe-block AES-256 kwama-byte ayi-16 kubhulokhi ngalinye.
I-Adiantum ingezwe ohlelweni olungaphansi lwe-fscrypt, Isetshenziselwa ukubethela ngokusobala amafayela nezikhombisi ku-ext4, f2fs, nakuzinhlelo zefayela ze-ubifs.
Esinye isici esingasigqamisa kulokhu kukhishwa sithi umshayeli we-AMDGPU ongeze ukusekelwa kobuchwepheshe bokuvumelanisa i-FreeSync (VESA Adaptive-Sync), ekuvumela ukuthi ulungise izinga lokuqabuleka kolwazi kusikrini sokuqapha ukuqinisekisa isikhathi sokuphendula esincane, ukukhipha okushelelayo, nokungabikho kokuphazamiseka phakathi kwemidlalo nevidiyo.
IFreeSync futhi ikuvumela ukuthi wehlise ukusetshenziswa kwamandla ngokunciphisa amandla wokuvuselela lapho isithombe esikrinini singashintshi.
Ukusekelwa kokuhlelwa kwememori ye-NVM kungezwe kulokhu kukhishwa kweKernel 5.0 ngemisebenzi yokuphepha eyakhelwe ngaphakathi njengokuvikela iphasiwedi, ukuhlanza nokukhiya.
Ingxenye ehlanganisiwe yesiqephu ukuvimba izintuba nokugwema ukulinganiselwa kwe-UEFI Secure Boot.
Kulesi sigaba, kufakwe amathuluzi ukulawula ukusetshenziswa kwe-kexec_load_file () call call, engasetshenziswa ukudlula i-UEFI Boot evikelekile ngokufaka iKernel evivinyiwe ngenye iKernel engasayiniwe ngamadijithi.
Disk subsystem, I / O, kanye nezinhlelo zamafayela
Kungezwe ikhono lokufaka ukwahlukaniswa kumafayili ngaphakathi kohlelo lwefayela le-Btrfs. Ifayela le-paging kuma-Btrfs kufanele ligcwaliswe ngokuphelele kumodi ye- "nocow" ngaphandle kokusebenzisa ukucindezelwa futhi libekwe kudrayivu eyodwa kuphela.
Uhlelo olungaphansi kwenethiwekhi
Nge-UDP, ikhono lokuthumela idatha kusokhethi yenethiwekhi lisetshenziswa ngemodi yokukopisha zero (thumela ikholi nefulegi le-MSG_ZEROCOPY), evumela ukudluliswa kwedatha kunethiwekhi ngaphandle kwesitoreji esiphakathi.
Isitaki se-UDP sisebenzisa ukusekelwa okuyisisekelo kwe-GRO (Generic Receive Offload) ukusheshisa ukucutshungulwa kwenani elikhulu lamaphakethe angenayo, engeza amaphakethe amaningi emabhuloki amakhulu angadingi ukucutshungulwa okuhlukile kwephakethe ngalinye.
Imemori yesistimu nezinsizakalo
Imodi entsha yokuhlela umsebenzi isetshenziselwe amaprosesa we-asymmetric ARM ngokususelwa kubakhiwo obukhulu., ehlanganisa amandla, kepha asebenzisa amandla, ama-CPU cores futhi angakhiqizi kangako, kepha ama-cores asebenzisa amandla amaningi.
Imodi entsha izokwenza ivumela ukunciphisa ukusetshenziswa kwamandla ngenxa yemisebenzi yokuvuka ikakhulu kuma-CPU cores.
Ngakolunye uhlangothi, ukuxhaswa kwemiyalo yeprosesa ye-WBNOINVD kungeziwe, kwasetshenziswa kuma-processor we-AMD nakwa-Intel ngokususelwa ekwakhiweni kwe-x86_64. Isitatimende esichaziwe siguqula wonke amashaneli e-cache aguqukile kuwo wonke amazinga wokuhlangana kwe-cache ngememori enkulu, ngenkathi kugcinwa amanani alondolozwe kunqolobane.
Ungayithola kanjani iKernel 5.0?
I-5.0 Kernel iyatholakala ukuze ilandwe ngqo kusuka ku- kernel.org uma ufuna ukuzihlanganisa ngokwakho.
Yize izotholakala nokusatshalaliswa kwakho kwe-Linux ezinsukwini ezizayo.
