Samsung tau tshaj tawm qhov kev xaiv tsav tsheb tshiab exFAT rau Linux ntsiav

Samsung qhia rau kev suav nrog hauv Linux ntsiav, txheej ntawm thaj ua rau thaj nrog kev siv tus tshiab exFAT tsav tsheb, raws li "sdfat" code puag tam sim no, tsim rau lub firmware ntawm Samsung Android smartphones. Yog tias thaj ua rau thaj tau txais, lawv yuav suav nrog hauv Linux 5.6 ntsiav, uas xav tias yuav raug tso tawm hauv 2-3 lub hlis. Piv rau exFAT tus tsav tsheb yav dhau los ntxiv rau cov ntsiav, tus tsav tsheb tshiab muab kev ua tau zoo ntawm kwv yees li 10%.

Qhov sib txawv tseem ceeb ntawm tsab ntawv sdfat tsav tsheb rau lub ntsiab Linux ntsiav thiab tus tsav tsheb siv los ntawm Samsung hauv Android:

• Cov cai nrog kev siv ntawm VFAT cov ntaub ntawv kaw lus tau raug tshem tawm, txij li cov ntaub ntawv no twb tau txais kev txhawb nqa hauv cov ntsiav (fs / rog);
• Tus tsav tsheb tau hloov npe los ntawm sdfat mus rau exfat;
• Cov cai tau raug refactored. Cov ntawv sau tau raug hloov kho raws li qhov yuav tsum tau ua rau code formatting rau Linux kernel;
• Kev ua haujlwm nrog metadata tau ua kom zoo dua qub, xws li tsim cov ntaub ntawv, tshawb nrhiav cov ntaub ntawv kaw lus (lookup) thiab txiav txim siab cov ntsiab lus ntawm cov npe (readdir).
• Cov teeb meem raug txheeb xyuas thaum kuaj ntxiv tau raug kho.

Cia peb ceeb toom koj tias tom qab Microsoft luam tawm pej xeem cov lus qhia tshwj xeeb thiab qhib kev siv tsis pub muaj nuj nqis ntawm exFAT patents ntawm Linux, tus tsav tsheb exFAT, kuj tsim los ntawm Samsung tab sis raws li keeb kwm code (version 1.2.9). Android firmware enthusiasts yog ported tus tsav tsheb tshiab sdFAT (2.x), tab sis Samsung nws tus kheej txiav txim siab los txhawb tus tsav tsheb no rau hauv lub ntsiab Linux ntsiav. Tsis tas li ntawd, Paragon Software qhib lwm tus tsav tsheb, yav tas los muab nyob rau hauv ib tug proprietary pawg tsav tsheb.

Lub exFAT cov ntaub ntawv tau tsim los ntawm Microsoft los kov yeej cov kev txwv ntawm FAT32 thaum siv rau ntawm lub peev xwm loj Flash drives. Kev them nyiaj yug rau exFAT cov ntaub ntawv kaw lus tau tshwm sim hauv Windows Vista Service Pack 1 thiab Windows XP nrog Service Pack 2. Qhov siab tshaj plaws cov ntaub ntawv loj piv rau FAT32 tau nthuav tawm los ntawm 4 GB rau 16 exabytes, thiab kev txwv ntawm qhov siab tshaj plaws muab faib loj ntawm 32 GB raug tshem tawm. , txhawm rau txo qhov tawg thiab ua kom nrawm, bitmap ntawm cov blocks dawb tau qhia, qhov txwv ntawm cov ntaub ntawv hauv ib phau ntawv tau nce mus rau 65 txhiab, thiab muaj peev xwm khaws ACLs.
