Yintoni eya kubakho Inguqulelo entsha yeLinux kernel 4.19 isasebenza kunye nabaphuhlisi bayo basebenza nzima kwaye kwezi ntsuku umthwalo wabo uphindaphindwe njengemingxunya yokhuseleko kwiiprosesa zangoku zigcina ababhekisi phambili be-Linux kernel bebambe kwaye benza iLinus Torvalds ikwimeko embi.
Kwakhona, Ukukhululwa komviwa ongu-4.19 kuzisa nenkqubo esekelayo yeGPS kunye nezinto ezahlukeneyo zokuphucula ukufikelela kwifayile nakwinethiwekhi.
Ngaba ukumiliselwa kwekernel kunokulibaziseka?
Intloko yenkozo, ILinus Torvalds, ichaze umjikelo wophuhliso wangoku njengo "khathazayo" hayi ngenxa yemingxunya yokhuseleko esandula ukubhengezwa. I-Linux 4.19 kwangaxeshanye kukhululwe ngokubanzi.
I-Linux kernel iphepha leetafile zokubekwa bucala esele zikhusele iinkqubo ezingama-64 ngokuchasene nokudibanisa umsantsa, ngelixa IKernel 4.19 ikwafumana iziqwengana zeenkqubo ezingama-32.
Kwakhona, Ezi bugs zokhuselo zangaphambili zokumiselwa zazingxamile.
Ngazo, iinkqubo zingasebenzisa i-cache yenqanaba 1 le-Intel CPUs ukufunda kwimemori engagunyaziswanga.
Oku iyingozi ngakumbi kwimeko ebonakalayo apho iinkqubo zeendwendwe zinokufikelela kumamkeli. Ukufumana iseti efanelekileyo ye-CPU, i-kernel ye-Linux isebenzisa umdwelisi nkqubo.
Ke abaphuhlisi bandise i-algorithm yabo ukurekhoda ixesha elifunekayo kwiinkqubo zexesha lokwenyani, ukuphazamisa, kunye nokulungelelanisa ixesha le-CPU ngokufanelekileyo.
Kwangelo xesha, ujongano lokubuza i-asynchronous I / O (I-Asynchronous I / O Poll Interface) ibuyela kwi-Linux kernel.
ILinus Torvalds ikhowudi iphinde yavavanywa okokuqala kungena kwiLinux 4.18 kwaye ayonelisekanga. Ngeli xesha, yabhabha isuka embindini.
Okwangoku, UGreg Kroah-Hartman unemincili ngenkqubo entsha ye-GPS oko kufakiwe kwikernel.
Oku kufanele ukuba "kuthambise bonke abaqhubi abaphambeneyo abebhabha ngeenxa zonke iminyaka, kunye nolunye uphumezo lwendawo yomsebenzisi."
Ukuphunyezwa okutsha kuhlobo olutsha lweKernel 4.19
Ukuza kuthi ga ngoku ikhowudi ilungele kuphela abafumana i-GNSS (isifinyezo sichaza iNkqubo yokuSebenza ngeSatellite yeHlabathi), kodwa sisiqalo esihle.
Kwakhona kwi-FSI Controller Subsystem (Ujongano lweNkxaso yeFlexible), uKroah-Hartman wafumana amazwi endumiso.
Kukho isystem entsha yendlela ephezulu yokuphuma kwebhasi ye-fan, enesiphumo esiphakamileyo somqhubi ngokubhekisele kumandla wokwahlula isiginali yedijithali yabamkeli abaninzi.
Umsebenzi wokucoca waba lixhoba leJprobes, indlela yokusebenza yekernel yokulandelela umnxeba. Ngoku ithathe indawo ye-Ftrace.
Ngezi patches zintsha kwisitaki senethiwekhi, abaphuhlisi beLinux kernel bazisa umsebenzi wokuhambisa ipakethi esekwe ixesha kwinto eya kuba lolu hlobo lutsha.
Oku ivumela amaxesha exesha apho i-kernel kufuneka ithumele iipakethi ze-red. Ijolise ikakhulu kwiinkqubo zexesha-lokwenyani, umzekelo kwicandelo lemveliso yemoto.
Kulapho kufuneka iqinisekise ukuhanjiswa kwedatha ethembekileyo kwaye, ngakumbi, kuthintele iipakethi ekufikeni emva kwexesha kwindawo ebesiya kuyo. Umsebenzi ulandela i-P802.1Qbv yenethiwekhi esemgangathweni.
Abaphuhlisi basebenza kwiCake (iZicelo eziQhelekileyo eziGcinelwe ukuPhuculwa,) ezibizwa ngokuba yiPatchset ngemicimbi eseleyo ngasemva kwee-routers kwinethiwekhi yasekhaya.
Ikhekhe lihleli ngqo kuthungelwano lwezixhobo zenethiwekhi kwaye lithathe isigqibo sokuba zeziphi iipakethi ezinokuhlala kulungelelwaniso lomgaqo.
Umgca olawulwa yiCake uyilelwe ukunqanda ukungqubana okugqithileyo kunye nemiba yokuhamba kade usebenzisa iindlela ezahlukeneyo. (njengokuvavanywa kwe-diffserv, i-algorithm emgceni olungileyo, kunye nefilitha ye-ACK).
Ikhekhe ijolise ikakhulu ekusetyenzisweni kwii-routers, njenge-Linux esekwe kwi-Open WRT yasimahla endaweni ye-firmware.
