Google yakabvisa rutsigiro rweRISC-V pa Android

RISC-V chivakwa mirayiridzo set (ISA) open source zvichibva pane yakaderedzwa yekuraira set concept (RISC). Iine 32, 64 uye 128 bit akasiyana, pamwe chete neakavhurika mataurirwo ayo akamutsa kufarira kukuru mukuvaka nharembozha.

Kune rumwe rutivi, Android ndeye OS inochinjika kune akasiyana madhizaini nemidziyo, izvi nekuda kwe "open source" hunhu. Kunyange Panguva iyo Google yakaratidza "rudo" rwayo rweRISC-V  panguva ye "RISC-V Summit 2022" yakaitwa muna Zvita uye yakataura zvinangwa zvayo zvekutsigira zviri pamutemo zvivakwa pa Android.

Kunyange zvakadaro, Zvinoita sekunge izvo zvakangoramba zviri mumashoko, kana kuti ndizvo zvakaratidzwa neGoogle munguva pfupi yapfuura zvigamba zvinobvisa RISC-V rutsigiro ACK (Android Common Kernel) inotsigira iyo RISC-V kernel, iyo RISC-V kernel kuvaka, uye iyo RISC-V emulator. Sarudzo iyi yaburitsa maonero akapatsanurwa, asi kazhinji, kushoropodza kwakanaya paGoogle.

Tal uye sezvo Android Authority inotsanangura: ACK ndiyo hwaro hwekernel yezvose zvigadzirwa zveAroid uye zvakare inopa yakabatana kernel hwaro hweAOSP. Zvichitaurwa zviri nyore, ACK iforogo yeGoogle yekukwira kumusoro kweLinux kernel, asi ine Android-chaiyo yewedzero yakawedzerwa iyo haisati yabatanidzwa mune mainline kana Long Term Support (LTS) kernel.

Kune akati wandei matavi e ACK, kusanganisira android-mainline, inova bazi guru rekusimudzira iro rinoita matavi ekernel "GKI" (kernel muchidimbu), chirongwa chakatangwa neGoogle ku gadzirisa dambudziko rekutsemuka kwekernel nekubatanidza.

Iyo GKI kernel inopa yakagadzikana kernel module interface (KMI) ye kernel modules, kuitira kuti module uye kernel zvigadziriswe zvakazvimirira. Imwe neimwe yakasimbiswa Android mudziyo inotakura ine kernel yakavakirwa pane rimwe reaya matavi eGKI, sezvo Google isiri kutsigira Android zvishandiso zvakavakwa neiyo mainline Linux kernel.

Neizvi, chaizvoizvoIyo inotevera vhezheni yeAndroid inoshandisa yazvino vhezheni yeGKI haizoenderane nayo midziyo ine machipisi RISC-V. Nekuda kweizvozvo, makambani arikuda kugadzira vhezheni yeAndroid yeRISC-V zvishandiso anozoda kuvandudza nekuchengetedza yavo yega yeLinux kernel vachishandisa RISC-V ACK zvigamba.

Zvisinei, Ichi chigamba chakabatanidzwa hachisi chekusingaperi, kubvira Google haina kubvisa zvachose kuwirirana neRISC-V, uye Google haina kuramba yakanyarara uye yakataura kuti kuzvipira kwayo kuRISC-V ndeyechokwadi uye pasinei nekupokana kwakagadzirwa neazvino zvigamba, Google yakavimbisa kuti inoramba ichitsigira RISC-V yezvivakwa pa Android.

Iyo kambani sinocherekedza kuti, nekuda kwekukurumidza kweiyo iterations, zvigadziriso zvakaitwa muiyo generic Android kernel mufananidzo (GKI), saka danho rakaitwa hazvireve kusiiwa kwekuedza kwayo kutora RISC-V.

Kuchengetedza kuenderana Android ine RISC-V, Google inoshanda pamwe chete nenharaunda uye chirongwa cheRISE (RISC-V Software Ecosystem), iyi nechinangwa chekumhanyisa kuwanikwa kwesoftware yekushanda kwepamusoro, yakaderera-simba RISC-V processors uye kwete yeAroid chete, asiwo yeLinux uye mamwe masisitimu anoshanda munzvimbo dzakasiyana dzekushandisa, dzakadai. seyakakwira performance computing.

Chekupedzisira, zvinofanirwa kutaurwa izvo Google haina kupa ruzivo nezve chikonzero kuseri kwekuburitswa kwezvigamba, asi zvinosimbisa kuti rutsigiro rweRISC-V pa Android haruna kubviswa zvachose, uye pane fungidziro yekuti danho iri rakakurudzirwa nemitemo yehurumende yakanangana nekumisa kukura kwekugadzira machipisi muChina uye izvo United States inotsvaga kumisa China kubva kushandisa iyo RISC-V yekuvakisa.

Kunyangwe izvi zvisina kunyatso kujeka, parizvino nesarudzo yeGoogle uye kuzvipira kwayo kusasiya kugarisana zvinogona kureva kuti isu tichafanirwa kumirira kwenguva yakareba kupfuura yaitarisirwa tisati taona madhizaini eAroid anoshanda neRISC-V machipi.
