Fue emasontweni ambalwa edlule inguqulo 5.0 ye-Linux kernel ikhishwe futhi yize le nguqulo yagcina itholakele iqembu lezentuthuko alikayeki ukusebenza kuzinguqulo ezilandelayo ze-kernel.
Futhi yilokho kuzinguqulo ezilandelayo ze-Linux Kernel 5.xx uhlelo olusha olungaphansi kwe- «Fieldbus» lungangeniswa (noma i-fieldbus), lokhu kungenzeka kulindeleke kusuka ku-Linux kernel version 5.2. Kufanele izuze ngokuyinhloko izilungiselelo zezimboni.
Mayelana ne-Fieldbus
Kubalulekile ukukhumbula ukuthi igama elithi Fieldbus (noma i-fieldbus) kubhekiswa kusethi ye- izivumelwano zenethiwekhi ezinikezelwe ku- ukulawula okwabiwe ngesikhathi sangempela kwezinhlelo zezimboni ezizenzakalelayo Ngokuvamile badinga uhlelo lokulawula olusatshalaliswayo kanye nohlelo oluhleliwe lwezinhlelo zokulawula ukuze lusebenze.
Ngokuvamile, phezulu kwalesi sikhundla sabaphathi kukhona isikhombimsebenzisi somshini womuntu (HMI) lapho opharetha angaqapha noma alawule khona uhlelo.
Phansi kochungechunge lokulawula yi-fieldbus edumile leyo Ixhuma ama-PLC ezingxenyeni lokho empeleni kwenza umsebenzi wenziwe (ama-switch, ama-contactors, ama-actuator, izinzwa, ama-valve, amalambu we-console, izinjini zikagesi…).
Ibhasi yasensimini ikuvumela ukuthi uxhume izinhlelo ezahlukahlukene, izinto noma izinsimbi ezindaweni ezahlukahlukene zezimboni.
Isebenza kwindwangu yenethiwekhi evumela uchungechunge, inkanyezi, indandatho, igatsha, kanye nezihloko zemithi.
Imininingwane ye-fieldbus ibilokhu ikhona amashumi eminyaka futhi lolu hlelo olungaphansi lwakhiwe ukuvumela amadivayisi ahlukile ukuthi enze shintshanisa idatha nge-fieldbus, kungaba yiProfinet, i-FLNet, noma okunye ukuqaliswa.
Uhlaka lwenzelwe ukuhlinzeka ngesixhumi esijwayelekile se-Fieldbus. Kokubili i-Linux kernel namadivayisi wesikhala somsebenzisi.
Inzuzo ezindaweni zezimboni
I-Profinet iyindinganiso yezobuchwepheshe embonini yokuxhumana kwedatha nge-Ethernet yezimboni, eyenzelwe ukuqoqa idatha nemishini yokulawula ezinhlelweni zezimboni, ngamandla akhethekile ekulethweni kwedatha ngaphansi kwemikhawulo yesikhathi eqinile (ye-oda le-1 ms noma ngaphansi).
Ikhadi le-profinet uqobo Ixhunywe ohlelweni ngebhasi lezimboni elibizwa nge 'anybus'.
Uhlamvu lwe- I-Linux 5.2 kufanele futhi yethule ukwesekwa kwamakhadi we-HMS Profinet Umsebenzi wawo omkhulu ukukhonza i-automation yezimboni esekwe ku-Ethernet futhi ehlala isebenzisa i-IEEE 802.3u: 100Mbit / s Fast Ethernet.
Leli zinga lokuxhumana I-Profinet isebenzisa i-TCP / IP namazinga obuchwepheshe bolwazi njenge: web server: HTTP, protocol protocol: SMTP, file Transfer: FTP).
I-Profinet futhi kuvumela ukusetshenziswa kobuchwepheshe beXML.
Uhlelo olusezingeni lwe-Linux Kernel fieldbus seluthole ukubuyekezwa komphakathi eziyishumi ezinyangeni ezedlule futhi kuthathwe njengokulungele ukusetshenziswa neLinux 5.2, okulindeleke ukuthi ibe yokugcina ngoJulayi 2019.
Olunye ushintsho lweKernel 5.2
Ngaphezu kokukwazi ukuthola inzuzo nge-Fieldbus, I-Linux kernel 5.2 nayo kulindeleke ukuthi ifike nezibuyekezo ezahlukahlukene ze-AMDGPU.
Njengoba abathuthukisi be-AMD abaphethe ukusekela abashayeli behluzo sebeqalile ukwenza omunye umsebenzi wokubuka okubandakanya ukwenza ikhodi yokuqaqa ejwayelekile ibe ejwayelekile nokunye ukulungiswa nokulungiswa.
Kukhona nokubuyekezwa okuningi kokuphathwa kwamandla / okubandakanya amandla, kufaka phakathi ukuxhaswa kwe-BACO (Bus Active, Chip Off) yamakhadi ane-Vega 12.
Ekugcineni kulindeleke nokuthi I-Linux kernel 5.2 ifaka inketho ye-GCC 9 Live Patching njengoba kuchaziwe osebenza naye ku-athikili yakhe (ungasivakashela kulesi sixhumanisi)
Lo ngumhlanganisi okufanele akhishwe emasontweni ambalwa ezayo. Le inketho eyenzelwe ukusiza ukukhiqiza ama-binaries asebenza kahle ukuze i-Live Patching isebenze.
Ngokufika kweLinux Kernel 5.2 le nketho izosetshenziswa ngokuzenzakalela, okungadala ukwehla kwejubane.
