Ettev\u00f5te Microsoft teatas<\/a><\/noindex> WSL2 (Windows Subsystem for Linux) v\u00f5imekuse laiendamise kohta, mis v\u00f5imaldab Linuxi t\u00e4idetavaid faile Windowsis k\u00e4itada.

Varasemalt, kui rakendused v\u00f5i kernel tarvitavad rohkem m\u00e4lu, eraldati m\u00e4lu WSL2 virtuaalmasinale, kuid see j\u00e4i p\u00e4rast seda kinnitatud ja ei naasetud s\u00fcsteemi, isegi kui ressursimahukas protsess l\u00f5petati ja eraldatud m\u00e4lu ei olnud enam vajalik. Memory Reclamation mehhanism v\u00f5imaldab vabastatud m\u00e4lu tagasi peamisele operatsioonis\u00fcsteemile \u00fcle anda ja automaatselt v\u00e4hendada virtuaalmasina m\u00e4lu suurust. Sellega tagastatakse mitte ainult m\u00e4lu, mida vabastavad kasutajaprotsessid, vaid ka m\u00e4lu, mida kasutatakse Linuxi k\u00e4rude vahem\u00e4lu jaoks. N\u00e4iteks, kui kettaga on suur aktiivsus, suureneb lehe vahem\u00e4lu suurus, kus failide sisu koguneb failis\u00fcsteemi toimimise ajal. P\u00e4rast k\u00e4su «echo 1 > \/proc\/sys\/vm\/drop_caches» t\u00e4itmist saab vahem\u00e4lu t\u00fchjendada ja m\u00e4lu tagasi peamisele operatsioonis\u00fcsteemile anda.<\/p>\n

Memory Reclamation'i rakendamine p\u00f5hineb
\npataljal<\/a><\/noindex>, mille Intel'i insenerid pakkusid v\u00e4lja Linuxi p\u00f5hikoodi lisamiseks, et laiendada virtio-ballooni draiveri v\u00f5imalusi ja m\u00e4lu haldust s\u00fcsteemis. M\u00e4rgitud patal on m\u00f5eldud kasutamiseks mis tahes k\u00fclalis\u00fcsteemides, et tagastada kasutamata m\u00e4lu lehek\u00fcljed host-s\u00fcsteemile ja v\u00f5ib rakendada erinevate h\u00fcperviisoritega. WSL2 puhul on patal kohandatud m\u00e4lu tagastamiseks Hyper-V h\u00fcperviisorile.<\/p>\n

Tuletame meelde, et WSL teises v\u00e4ljaandes erineb<\/a><\/noindex> tarnitakse t\u00e4ielikku Linuxi kernelit, mitte emulaatorit, mis k\u00e4itub Linuxi s\u00fcsteemi k\u00f5nesid Windowsi s\u00fcsteemi k\u00f5nedeks. WSL2-s tarnitav Linuxi kernel<\/a><\/noindex> p\u00f5hineb v\u00e4ljaandel 4.19, mida k\u00e4itatakse Windowsi keskkonnas Azure'is juba kasutatavas virtuaalkeskkonnas. Linuxi kernelile m\u00f5eldud v\u00e4rskendused toimetatakse Windows Update'i mehhanismi kaudu ja testitakse Microsofti pideva integreerimise infrastruktuuris. WSL2-s kasutatavad kernelile spetsiifilised pataljad sisaldavad optimeerimist, et v\u00e4hendada kernelite k\u00e4ivitamise aega, v\u00e4hendada m\u00e4lu tarbimist ja j\u00e4tta kernelisse minimaalne vajalik draiverite ja alams\u00fcsteemide kogum.<\/p>\n
