Kev tso tawm ntawm lub platform qhib webOS Open Source Edition 2.17 tau luam tawm, uas tuaj yeem siv rau ntau yam khoom siv nqa tau yooj yim, cov laug cam thiab lub tsheb infotainment systems. Raspberry Pi 4 boards raug suav hais tias yog lub platform siv kho vajtse.Lub platform yog tsim nyob rau hauv cov chaw khaws ntaub ntawv pej xeem raws li Apache 2.0 daim ntawv tso cai, thiab kev txhim kho yog saib xyuas los ntawm cov zej zog, ua raws li kev sib koom tes kev tswj hwm tus qauv.
Lub webOS platform yog Ameslikas tsim los ntawm Palm hauv 2008 thiab tau siv rau ntawm Palm Pre thiab Pixie smartphones. Hauv xyoo 2010, tom qab kev tswj hwm ntawm Palm, lub platform dhau mus rau hauv tes ntawm Hewlett-Packard, tom qab ntawd HP sim siv lub platform no hauv nws cov tshuab luam ntawv, ntsiav tshuaj, laptops thiab PCs. Xyoo 2012, HP tshaj tawm cov kev txhais ntawm webOS rau hauv ib qho kev ywj pheej qhib qhov project thiab hauv 2013 pib qhib qhov chaws ntawm nws cov khoom. Hauv 2013, lub platform tau yuav los ntawm Hewlett-Packard los ntawm LG thiab tam sim no siv rau ntau tshaj 70 lab LG TVs thiab cov neeg siv khoom siv. Xyoo 2018, webOS Open Source Edition project tau tsim, dhau los ntawm LG tau sim rov qab mus rau qhov qhib kev tsim qauv, nyiam lwm tus neeg koom thiab nthuav dav ntau yam khoom siv txhawb nqa hauv webOS.
Lub webOS system ib puag ncig yog tsim los siv OpenEmbedded cov cuab yeej thiab cov pob hauv paus, nrog rau kev tsim thiab cov txheej txheem metadata los ntawm Yocto project. Cov khoom tseem ceeb ntawm webOS yog qhov system thiab daim ntawv thov tus thawj tswj hwm (SAM, System thiab Application Manager), uas yog lub luag haujlwm rau kev khiav haujlwm thiab kev pabcuam, thiab Luna Surface Manager (LSM), uas tsim cov neeg siv interface. Cov Cheebtsam yog sau siv Qt lub moj khaum thiab Chromium browser cav.
Rendering yog ua los ntawm tus thawj tswj kev sib xyaw siv Wayland raws tu qauv. Txhawm rau tsim cov ntawv thov kev cai, nws tau thov kom siv lub vev xaib thev naus laus zis (CSS, HTML5 thiab JavaScript) thiab Enact lub moj khaum, raws li React, tab sis nws kuj tseem tuaj yeem tsim cov kev pab cuam hauv C thiab C ++ nrog Qt-based interface. Cov neeg siv lub plhaub thiab cov ntawv sau ua ke yog siv los ua cov kev pab cuam ib txwm sau siv QML thev naus laus zis. Lub neej ntawd Lub Tsev Launcher plhaub yog qhov ua tau zoo rau kev tswj lub vijtsam kov thiab muab lub tswv yim ntawm kev hloov daim duab qhia chaw (tsis yog lub qhov rais).
Txhawm rau khaws cov ntaub ntawv hauv ib daim ntawv uas siv JSON hom, DB8 cia siv, siv LevelDB database ua tus backend. Bootd yog siv rau kev pib ua raws li systemd. Lub uMediaServer thiab Media Display Controller (MDC) subsystems muaj rau kev ua cov ntsiab lus multimedia; PulseAudio yog siv los ua lub suab server. Txhawm rau hloov kho cov firmware hloov tshiab, OSTree thiab atomic muab faib hloov pauv tau siv (ob qhov kev faib ua haujlwm tau tsim, ib qho yog siv, thiab qhov thib ob yog siv los luam qhov hloov tshiab).
Cov kev hloov tseem ceeb hauv qhov kev tso tawm tshiab:
- Txhim kho kev teb thaum tuav lub vijtsam kov
- PulseAudio suab neeg rau zaub mov tau hloov kho rau version 15.0 (yav dhau los version 9.0 tau siv).
- Lub webOS Edge AI lub moj khaum nrog lub tshuab kev kawm cov tsev qiv ntawv TensorflowLite, Arm Compute thiab Edge AI Vision 1.0 suav nrog (tuaj yeem siv tau, piv txwv li, paub txog lub ntsej muag thiab khoom).
- Lub emulator txhawb VLAN.
