Okuzoba khona inguqulo entsha yeLinux kernel 4.19 isasebenza futhi abathuthukisi bayo basebenza kanzima futhi kulezi zinsuku umthwalo wabo wokusebenza uphindeke kabili njengoba izimbobo zokuphepha kuma-processor wamanje zigcina onjiniyela be-Linux kernel bebambe futhi benza iLinus Torvalds ibe nesimo esibi.
Futhi, okhethwayo wokukhishwa we-4.19 futhi uletha isistimu esephansi ye-GPS nezithuthukisi ezahlukahlukene zokufinyelela kwefayela nenethiwekhi.
Kungenzeka yini ukuthi ukwethulwa kernel kubambezeleke?
Inhloko yomhlamvu, ILinus Torvalds, ichaze umjikelezo wamanje wentuthuko "njengowukhathazayo" hhayi nje ngenxa yezimbobo zokuphepha ezisanda kumenyezelwa. I-Linux 4.19 ngasikhathi sinye ingukukhishwa okubanzi.
Amachashazi wokuhlukaniswa kwetafula le-Linux kernel asevele evikela amasistimu angama-64-bit ekuhlanganiseni igebe, ngenkathi IKernel 4.19 ibuye ithole iziqeshana zezinhlelo ezingama-32-bit.
Futhi, Lezi zinambuzane ezisanda kutholakala zokulungiselela ukulungiswa zazipheshulwa.
Ngazo, izinqubo zingasebenzisa inqolobane yeleveli 1 yama-Intel CPU ukufunda imemori engagunyaziwe.
Lokhu kuyingozi ikakhulukazi ezindaweni ezibonakalayo lapho izinhlelo zezivakashi zikwazi ukufinyelela kumgcini. Ukuthola ukusethwa kwewashi okufanele kwe-CPU, i-Linux kernel isebenzisa umqambi wohlelo.
Ngakho-ke onjiniyela bandise i-algorithm yabo ukurekhoda isikhathi esidingekayo sezinqubo zesikhathi sangempela, ukuphazamisa, nokulungisa isikhathi se-CPU ngokufanele.
Ngasikhathi sinye, isikhombimsebenzisi sokubuza i-asynchronous I / O (I-Asynchronous I / O Poll Interface) ibuyela ku-Linux kernel.
ILinus Torvalds ibuye yahlolwa ikhodi ekungeneni kokuqala kweLinux 4.18 futhi ayenelisekanga. Khonamanjalo, yandiza yasuka enkabeni.
Okwamanje, UGreg Kroah-Hartman ujabule ngohlelo olusha lwe-GPS lokho kufakiwe ku-kernel.
Lokhu kufanele "kuthambise bonke abashayeli abasangene abakade bezulazula iminyaka, kanye nokusetshenziswa kwesikhashana komsebenzisi."
Ukuqaliswa okusha kunguqulo entsha yeKernel 4.19
Kuze kube manje ikhodi ilungele kuphela abamukeli be-GNSS (isifinyezo sisho iGlobal Navigation Satellite System), kepha lesi yisiqalo esihle.
Futhi nge-FSI Controller Subsystem (I-Flexible Support Interface), uKroah-Hartman wathola amazwi okudumisa.
Kukhona isistimu entsha yebhasi le-fan elikhipha abalandeli abaningi, ngokukhishwa okuphezulu kwe-fan kubhekiswe emandleni okuhlukanisa isignali yedijithali yabamukeli abaningi.
Umsebenzi wokuhlanza waba isisulu kuJprobes, inqubo ye-kernel call trace mechanism. Manje isithathele indawo i-Ftrace.
Ngalezi zigcawu ezintsha zesitaki senethiwekhi, abathuthukisi be-Linux kernel bethula umsebenzi wokuhambisa iphakethe osuselwa esikhathini kulokho okuzoba le nguqulo entsha.
Lokhu ivumela izinkathi zesikhathi lapho i-kernel kufanele ithumele khona amaphakethe we-red. Ibhekiswe ikakhulukazi ezinhlelweni zesikhathi sangempela, ngokwesibonelo emkhakheni wokukhiqiza imoto.
Lapho kufanele kuqinisekiswe ukudluliswa kwedatha okuthembekile futhi, ikakhulukazi, kuvimbele amaphakethe ukuthi afike sekwephuze kakhulu lapho eya khona. Umsebenzi ulandela i-P802.1Qbv ejwayelekile yenethiwekhi.
Abathuthukisi basebenzela Ikhekhe (Izicelo Ezijwayelekile Zigcinwa Zithuthukisiwe,) ezibizwa ngePatchset ngezinkinga ezisilele ngemuva kwama-routers kumanethiwekhi asekhaya.
Ikhekhe lihlala ngqo kusixhumi esibonakalayo sehadiwe futhi linquma ukuthi imaphi amaphakethe angahlala kusixhumi esibonakalayo se-protocol.
Ulayini ophethwe amaKhekhe wenzelwe ukugwema izingqinamba ezixakile nezokubambezeleka ngokusebenzisa izindlela ezahlukahlukene. (njengokuhlolwa kwe-diffserv, i-algorithm emugqeni olungile, nesihlungi se-ACK).
Ikhekhe lihloselwe ukusetshenziswa kuma-routers, njengokushintshwa kwe-firmware esekwe ku-Linux Open-WRT.
