Open sourced hy­per­vi­sor project to en­able IoT de­vice de­vel­op­ment

OpenSource For You - - Foss Bytes -

Yet an­other in­ter­est­ing hy­per­vi­sor project has been an­nounced by The Linux Foun­da­tion. The project will pro­vide a frame­work for in­dus­try lead­ers to build an open source em­bed­ded hy­per­vi­sor specif­i­cally for the In­ter­net of Things (IoT).

This new em­bed­ded ref­er­ence hy­per­vi­sor project is called ACRN (pro­nounced ‘acorn’). With en­gi­neer­ing and code con­tri­bu­tions from In­tel Cor­po­ra­tion, the hy­per­vi­sor was built with re­al­time and safety-crit­i­cal­ity in mind, and op­ti­mised to stream­line em­bed­ded de­vel­op­ment.

ACRN com­prises two main com­po­nents: the hy­per­vi­sor and its de­vice model— com­plete with rich I/O me­di­a­tors. In­tel’s ex­pe­ri­ence and lead­er­ship in vir­tu­al­i­sa­tion tech­nol­ogy were key to the ini­tial de­vel­op­ment of this hy­per­vi­sor so­lu­tion.

ACRN’s small, real-time foot­print will help de­vel­op­ers. Con­sol­i­dat­ing a di­verse set of IoT work­loads with mixed-crit­i­cal­ity on to a sin­gle plat­form

helps re­duce both de­vel­op­ment and de­ploy­ment costs, al­low­ing for a more stream­lined sys­tem ar­chi­tec­ture—for ex­am­ple, elec­tronic con­trol unit (ECU) con­sol­i­da­tion in au­to­mo­tive ap­pli­ca­tions.

Though open source hy­per­vi­sor op­tions are cur­rently avail­able, none share ACRN’s vi­sion of an open source hy­per­vi­sor so­lu­tion op­ti­mised for em­bed­ded and IoT prod­ucts.

“ACRN’s op­ti­mi­sa­tion for re­source-con­strained de­vices, its fo­cus on iso­lat­ing safety-crit­i­cal work­loads and giv­ing them pri­or­ity, make the project ap­pli­ca­ble across many IoT use cases. We’re pleased to wel­come project ACRN and in­vite em­bed­ded de­vel­op­ers to get in­volved in the new com­mu­nity,” said Jim Zem­lin, ex­ec­u­tive di­rec­tor of The Linux Foun­da­tion.

ACRN is open to in­cor­po­rate in­put from the open source, em­bed­ded, and IoT de­vel­oper com­mu­ni­ties. The project will en­cour­age col­lab­o­ra­tion and code con­tri­bu­tions to the project. As of now, ADLINK, Ap­tiv, In­tel Cor­po­ra­tion, LGE, and Neu­soft Cor­po­ra­tion have al­ready joined the ACRN project.

ACRN will have a Linux-based ser­vice OS and the abil­ity to si­mul­ta­ne­ously run mul­ti­ple types of guest op­er­at­ing sys­tems, pro­vid­ing a pow­er­ful so­lu­tion for work­load con­sol­i­da­tion.
