I-Rust manje isilungele ukujoyina i-C njengolimi olusebenzayo oluzosetshenziswa ku-Linux
Lo nyaka ka-2022 kungaba unyaka weRust ngaphakathi kwe-Linux kernel, kusukela I-Rust ye-Linux cishe isilungele i-Linux kernel version 6.1. Yilokhu okuvela enkulumweni yakamuva kaLinus Torvalds engqungqutheleni yokugcina yomthombo ovulekile.
Futhi kungenxa yokuthi abagcini abakhulu be-Linux kernel bajwayelene nolimi luka-C oseluvele lucatshangelwa iminyaka yobudala, njengoba abanye besondela ngisho namashumi ayisithupha, kuyilapho isizukulwane esisha sabanakekeli abaneminyaka engamashumi amathathu sikhuphuka, okungenzeka kwenyuse ubunzima bokuthola abalondolozi be-Linux kernel uma ukuthuthukiswa kwayo kuqhubeka ngolimi C.
Ngesikhathi se-Open Source Summit Europe, kumenyezelwe uLinus Torvalds ukuthi, ukuvimbela izinkinga ezingalindelekile, sfuthi izofaka ama-patches ukusekela ukuthuthukiswa komshayeli we-Rust ku-Linux 6.1 kernel, okulindeleke ukuthi ikhishwe ngoDisemba.
Abanye wezinzuzo zokuthola ukwesekwa kwe-Rust ezinhlamvini zenza kube lula ukubhala izilawuli yamadivayisi avikelekile ngokunciphisa amathuba okuba namaphutha enkumbulo futhi ukhuthaze abathuthukisi abasha ukuthi babambe iqhaza ku-kernel.
“Ukugqwala kungenye yezinto engicabanga ukuthi izoletha ubuso obusha... siyaguga futhi sibe mpunga,” kusho uLinus.
Amanothi okukhishwa kwe I-Linux 6.0 rc1 inikeza isibuyekezo ngenqubekelaphambili yephrojekthi ye-Rust ye-Linux: kuneqembu elisebenzayo elihlobene, umshayeli wokuqala wesitoreji se-NVMe semidiya ethuthukiswe ngalolo limi uyatholakala, kanye nomshayeli weseva ehloselwe iphrothokholi yenethiwekhi ye-9P.
Nokho, iqembu liyaqhubeka nokubhekana nobunzima ngokwakha. Eqinisweni, kwenziwa nge-GCC ye-kernel ngenkathi i-Rust isenayo i-LLVM. I-Rust interface ye-GCC iyasebenza, kodwa isinyathelo sisaqala.
Ukuqala kokusekelwa kwe-Rust yokuthuthukiswa kwe-Linux kernel kubhekwa "isinyathelo esibalulekile ukuze bakwazi ukubhala izilawuli ngolimi oluvikeleke kakhulu.” I-Mozilla Research's Rust iwuhlobo lolimi lokuhlela labo ababhala ikhodi yezinhlelo eziyisisekelo zokufaka/okuphumayo (BIOS), izilayishi zebhuthi, amasistimu okusebenza, njll. ube nentshisekelo
Ngokusho kwababukeli, ikusasa lezinhlelo zesistimu kunolimi C. Eqinisweni, ochwepheshe bathi inikeza iziqinisekiso zokuphepha ezingcono zesofthiwe kune-C/C++ pair. Kwa-AWS, bacacisa ukuthi ukukhetha i-Rust kumaphrojekthi wokuthuthukisa kusho ukungeza ukusebenza kahle kwamandla nokusebenza kwe-C ukuze kuzuze ukuphepha.
U-Linus uphinde wamemezela ukuthi inguqulo 6.1 ye-kernel izothuthukisa ezinye zezingxenye ezindala kanye nezisekelo ze-kernel, njengomsebenzi we-printk(). Ngaphezu kwalokho, uLinus ukhumbule ukuthi emashumini ambalwa eminyaka edlule, i-Intel yazama ukumkholisa ukuthi iprosesa ye-Itanium kwakuyikusasa, kodwa waphendula.
“Cha, ngeke kwenzeke lokhu, ngoba ayikho inkundla yentuthuko. I-ARM yenza konke kahle." «
Enye inkinga uTorvalds ayivezile ukungahambisani ekukhiqizeni ama-ARM processors:
"izinkampani ze-hardware ezihlanya ezivela e-Wild West, zenza ama-chips akhethekile emisebenzi ehlukahlukene." Wanezela ukuthi "kwakuyindaba enkulu lapho amaprosesa okuqala ephuma, namuhla kunezindinganiso ezanele zokwenza kube lula ukudlulisa ama-cores kuma-ARM processors amasha."
Futhi, singakhomba ukukhululwa kokuqaliswa kokuqala komshayeli we-rust-e1000 wama-adaptha e-Intel Ethernet, abhalwe ngokwengxenye ku-Rust.
Ikhodi isenocingo oluqondile kwezinye izibopho ze-C, kodwa umsebenzi uyenziwa kancane kancane ukuze kufakwe okunye futhi kwengezwe izifinyezo ze-Rust ezidingekayo ukuze kubhalwe abashayeli benethiwekhi (ukufinyelela i-PCI, i-DMA, nama-API enethiwekhi ye-kernel). Ngendlela yayo yamanje, umshayeli uphase ngempumelelo ukuhlolwa kwe-ping lapho efakwe ku-QEMU, kodwa namanje ayikasebenzi ngehardware yangempela.
Okokugcina Uma unesifiso sokwazi okwengeziwe ngakho, ungabheka imininingwane Kulesi sixhumanisi esilandelayo.
