Ukusetshenziswa kwemishini ezimele efakwe ezimeni ezibucayi zokuphephanjengamarobhothi ezimboni noma izimoto ezingashayeli, isbkuphakamisa inkinga yokuthembela mayelana nehardware uqobo.
Ukubhekana nalokhu kukhathazeka, iLinux Foundation yethule lolu hlelo yethula iphrojekthi entsha ye-ELISA (Ukunikwa amandla kweLinux kuhlelo lokuphepha), kuhloswe ukusebenzisa iLinux kuzixazululo ezidinga ukuthembeka okuphezulu (izinhlelo ezibucayi kwezokuphepha), ukwehluleka kwazo okungasongela izimpilo zabantu, kulimaze imvelo noma kuholele ekulimaleni okukhulu kwemishini.
Abasunguli bephrojekthi entsha yi-Arm, BMW, KUKA, Linutronix neToyota.
UKate Stewart, umphathi omkhulu wezinhlelo zamasu weLinux Foundation, cZonke izimboni ezinkulu zifuna "ukusebenzisa iLinux ukuphepha kwezicelo ezibucayi ngoba kubenza bakwazi ukuthola imikhiqizo yabo ukuze bathengise ngaphezulu »ngokushesha futhi banciphise ubungozi bamaphutha wokuklama abucayi«.
Ngokusho kwakhe, inselelo enkulu ibisalokhu ikhona "Ukushoda kwemibhalo ecacile namathuluzi okukhombisa ukuthi uhlelo olususelwa kwiLinux luyahlangabezana nezidingo zokuphepha zokuthola isitifiketi."
UKate stewart uvumile ukuthi imizamo yangaphambilini yokuxazulula le nkinga ayizuzanga impumelelo ebilindelekile ekusunguleni indlela yokusebenza okuxoxwa kabanzi futhi kwamukelwa, kepha kubonakala kuqinisekile ukuthi nge-ELISA konke kuzohluka:
“Sizokwazi ukusizakala ngengqalasizinda kanye nokwesekwa ngumphakathi obanzi weLinux Foundation odingekayo ukwenza lolu hlelo lube yimpumelelo,” kusho yena.
Mayelana ne-ELISA
Njengengxenye yephrojekthi, kuhlelwe ukuthuthukisa amathuluzi nezinqubo zokwakha futhi kuqinisekiswe izixazululo ezethembekile ezisezingeni eliphakeme ezisuselwa ku-Linux kanye nesoftware yomthombo ovulekile ezingasetshenziswa ezindaweni ezifana nezokuthutha, ukukhiqiza, ukunakekelwa kwezempilo namandla.
Isibonelo, imvelo yeLinux okulungiselelwe kungasetshenziselwa ukuhlomisa amarobhothi ezimboni, amadivayisi wezokwelapha, amasistimu wokuzenzekelayo wezimboni, izinhlelo zezimoto, nezimoto ezizimele.
Ukwethulwa kwe U-ELISA ulandela ukukhishwa ngonyaka odlule kwe-Automotive Grade Linux (I-AGL) i-5.0, inguqulo yakamuva yephrojekthi yeLinux Foundation yokuletha ubuchwepheshe bemithombo evulekile embonini yezimoto.
Izinhlobo zangaphambilini bezigxile kuzinhlelo ze-infotainment, kodwa inguqulo 5.0 yethule izixazululo ze-telematics nezemephu ezivumela ama-OEMs ukuthi abelane ngemininingwane yemephu ekhiqizwe yizimoto ezizimele, ngaphezu kokunikeza ukuphepha okukhulu.
phakathi izinhloso zephrojekthi, futhi kukhulunywa ngokwakhiwa kwemibhalo eyizethenjwa nezibonelo zokusetshenziswa, ukuthi ungabafundisa kanjani abathuthukisi bemithombo evulekile ukuthi bangayakha kanjani ikhodi ephephile nethembekile, sebenzisana nomphakathi ukuqinisekisa isoftware esezingeni eliphakeme, ukulandelela izehlakalo ezingaba khona nezinsongo zokuthuthukiswa kwengxenye ebucayi, nokwethula izindlela ezinhle zokuphendula ngokushesha. ezindabeni ezivelayo.
Njengesisekelo se-ELISA, kukhona amaphrojekthi ayisisekelo i-SIL2LinuxMP (Imvelo ye-GNU / Linux isikwe i-RTOS) neLinux ngesikhathi sangempela (PREEMPT_RT).
Ikakhulu, sIzakhiwo zabuyekezwa, ikhodi yabhalwa kabusha, ingqalasizinda yokusingatha ukuphazamiseka yahlelwa kabusha, futhi kwacatshangelwa neziphakamiso zokusebenzisa i-printk..
Ngemuva kokuphothula ukuhlolwa kwama-PREEMPT_RT patches, izinguquko ngazinye zihlelelwe ukukhishwa kumgogodla we-kernel.
Ukwenza umsebenzi ube nzima, Ukuthunyelwa kwesikhathi sangempela kudinga ushintsho olubalulekile kumasystems ekhiye we-kernel, kufaka phakathi ama-timers, ama-schedule schedule, izindlela zokukhiya, nokuphazamisa izibambi, kanye nesidingo sabo bonke abashayeli bedivayisi ukuhlangabezana nezimfuneko ezithile zokwenza umsebenzi wesikhathi sangempela.
Imithwalo yemfanelo ye-ELISA kufanele igxile ekwakhiweni kwemibhalo eyizethenjwa nezimo zokusetshenziswa ezahlukahlukene, imininingwane evela kumthombo ovulekile womphakathi ngezindlela ezinhle kakhulu zobunjiniyela bezokuphepha kanye nokwenza kusebenze "impendulo eqhubekayo" yokwenza ngcono izinqubo kanye nokwenza izivivinyo zokulawula ikhwalithi.
Futhi, inhlangano izosiza amalungu aqaphe izingozi nezinto ezibucayi zohlelo futhi abeke isisekelo seqoqo lemithetho amaqembu okuphendula amalungu angalandela uma kunenkinga.
