Kwakunjalo kwiiveki ezimbalwa ezidlulileyo, inguqulelo engu-5.0 yeLinux kernel yakhutshwa kwaye nangona le nguqulo yagqitywa Iqela lophuhliso alizange liyeke ukusebenza kwiinguqulelo ezilandelayo zekernel.
Kwaye oko Kwiinguqulelo ezilandelayo zeLinux Kernel 5.xx inkqubo entsha esezantsi «I-Fieldbus» inokungeniswa ) Kuya kufuneka izuze ikakhulu kuseto lweshishini.
Malunga ne-Fieldbus
Kubalulekile ukuba ukhumbule ukuba igama elithi Fieldbus (okanye i-fieldbus) ibhekisa kwiseti ye iinkqubo zomsebenzi womnatha ezinikezelwe ulawulo lwexesha lokwenyani lweenkqubo ezizenzekelayo zeshishini Ngokubanzi bafuna inkqubo yolawulo esasaziweyo kunye nolawulo oluphezulu lweenkqubo zolawulo ukuze zisebenze.
Ngokuqhelekileyo, phezulu kolu luhlu luphawu lomatshini lomntu (HMI) apho umsebenzisi anokujonga okanye alawule inkqubo.
Emazantsi yolawulo lwekhonkco yintsimi edumileyo leyo idibanisa ii-PLCs kumacandelo loo nto yenza ukuba umsebenzi wenziwe (iitshintshi, ii-contactors, ii-actuators, iisenzi, iivelufa, izibane zekhonsoli, iinjini zombane…).
Ibhasi yasentsimini ikuvumela ukuba uqhagamshele iinkqubo ezahlukeneyo, izinto okanye izixhobo kwiindawo ezahlukeneyo zorhwebo.
Isebenza kwilaphu lenethiwekhi evumela ikhonkco, inkwenkwezi, isangqa, isebe, kunye neetopiki zomthi.
Inkcazo ye-fieldbus sele ikho amashumi eminyaka kwaye le nkqubo iphantsi ivelisiwe ukuvumela izixhobo ezahlukeneyo ukuba utshintshiselana ngedatha kwi-fieldbus, nokuba yiProfinet, i-FLNet, okanye olunye uphumezo.
Isakhelo siyilelwe ukubonelela ngesixhobo esibonakalayo generic yeFildbus. Zombini izixhobo zelinux kunye nezixhobo zesithuba somsebenzisi.
Isibonelelo kwimeko zeshishini
I-Profinet ngumgangatho wobugcisa kumzi mveliso kunxibelelwano lwedatha kwi-Ethernet yemizi-mveliso, eyilelwe ukuqokelela idatha kunye nezixhobo zolawulo Kwiinkqubo zamashishini, ngamandla akhethekileyo ekuhanjisweni kwedatha phantsi kwemida engqongqo yexesha (yomyalelo we-1 ms okanye ngaphantsi).
Ikhadi leprofinet uqobo Idityaniswe nenkqubo ngebhasi yomzi mveliso ebizwa ngokuba yi 'anybus'.
Intsimbi ye I-Linux 5.2 kufuneka yazise ngenkxaso yamakhadi e-HMS Profinet Umsebenzi wawo ophambili kukusebenzela oomatshini abazihambelayo abasekwe kwi-Ethernet kwaye bahlala besebenzisa i-IEEE 802.3u: 100Mbit / s Fast Ethernet.
Umgangatho wonxibelelwano Inzuzo isebenzisa i-TCP / IP kunye nemigangatho yetekhnoloji yolwazi enje nge: web server: HTTP, protocol protocol: SMTP, transfer file: FTP).
Inzuzo Ikwavumela ukusetyenziswa kwetekhnoloji yeXML.
Inkqubo esezantsi ye-Linux Kernel ye-fieldbus ifumene uphononongo loluntu kwiinyanga nje ezidlulileyo kwaye ithathwa njengelungele ukusetyenziswa neLinux 5.2, ekulindeleke ukuba igqitywe ngoJulayi 2019.
Olunye utshintsho lweKernel 5.2
Ukongeza ekubeni nakho ukufumana isibonelelo nge-Fieldbus, I-Linux kernel 5.2 ikwalindeleke ukuba ifike nohlaziyo lwe-AMDGPU.
Okoko abaphuhlisi be-AMD abajongene nokuxhasa abaqhubi bemizobo sele beqalile ukwenza omnye umsebenzi wokubona ezibandakanya ukwenza ikhowudi yokuqengqeleka yokuqalisa ukuba ibe yinto eqhelekileyo kunye nolunye ulungiso kunye nezixhasi.
Kukwakho nenani lokuhlaziywa kwamandla ombane / lokulawula amandla, kubandakanya iBACO (iBus Active, iChip Off) inkxaso yamakhadi aneVega 12.
Okokugqibela kulindeleke ukuba I-Linux kernel 5.2 ibandakanya ukhetho lwe-GCC 9 Live Patching okoko kuchaziwe ngumlingane kwinqaku lakhe (ungandwendwela kule khonkco)
Esi sisihlanganisi ekufuneka sikhutshiwe kwiiveki ezimbalwa ezizayo. Olu khetho luyilelwe ukunceda ukuvelisa ii-binaries ezisebenza kakuhle kwi-Live Patching ukuze zisebenze.
Ngokufika kweLinux Kernel 5.2 olu khetho luya kusetyenziswa ngokungagqibekanga, okunokubangela ukwehla kwesantya.
