Iyo itsva vhezheni yemutyairi weexFAT yakarongedzerwa iyo Linux kernel

Korean developer Park Ju Hyung, inyanzvi mukutakura Android firmware yemidziyo yakasiyana-siyana, kuunzwa itsva edition yemutyairi weiyo exFAT faira system - exfat-linux, iri forogo kubva kumutyairi we "sdFAT", developed kubudikidza Samsung. Parizvino, bazi rekuita reLinux kernel ratova akawedzera Samsung's exFAT mutyairi, asi yakavakirwa pacodebase mutyairi wekare bazi (1.2.9). Parizvino, Samsung inoshandisa yakatosiyana vhezheni ye "sdFAT" (2.2.0) mutyairi mune yayo smartphones, bazi iro raive kuvandudzwa kwePark Ju Hyung.

Pamusoro pekuchinja kune yazvino kodhi base, iyo yakatsanangurwa exfat-linux mutyairi inosiyaniswa nekubviswa kweiyo Samsung-chaiyo shanduko, sekuvapo kwekodhi yekushanda neFAT12/16/32 (FS data inotsigirwa muLinux ne. vakaparadzana vatyairi) uye yakavakirwa-mukati defragmenter. Kubvisa zvinhu izvi kwakaita kuti zvikwanisike kuita kuti mutyairi agone kutakurika uye aigadzirise kune yakajairwa Linux kernel, uye kwete kungoita kernels inoshandiswa muSamsung Android firmware.

Mugadziri aitawo basa kurerutsa kuisa mutyairi. Vashandisi veUbuntu vanogona kuimisa kubva PPA repository, uye nekumwe kugovera, ingo dhawunirodha kodhi uye mhanya "ita && gadzira". Mutyairi anogona zvakare kuunganidzwa pamwe chete neLinux kernel, semuenzaniso pakugadzirira firmware yeApple.

Mune ramangwana, zvakarongwa kuchengetedza mutyairi kusvika parizvino nekufambisa shanduko kubva kune hombe Samsung kodhi base uye kuitakura kune itsva kernel kuburitswa. Parizvino, mutyairi akaedzwa paakavakwa nekernels kubva pa3.4 kusvika 5.3-rc pane x86 (i386), x86_64 (amd64), ARM32 (AArch32) uye ARM64 (AArch64) mapuratifomu. Munyori wekusiyana kwemutyairi mutsva akakurudzira kuti vanogadzira kernel vatarise kusanganisira mutyairi mutsva mubazi rekuita sehwaro hweiyo yakajairwa exFAT kernel mutyairi, panzvimbo peiyo ichangobva kuwedzerwa yemazuva akasiyana.

Miedzo yekushanda yakaratidza kuwedzera kwekumhanya kwekunyora mashandiro kana uchishandisa mutyairi mutsva. Pakuisa chikamu mu ramdisk: 2173 MB/s kupesana ne1961 MB/s ine sequential I/O, 2222 MB/s inopesana ne2160 MB/s nekuwana zvisina tsarukano, uye kana uchiisa chikamu muNVMe: 1832 MB/s kupesana ne1678 MB. /s uye 1885 MB/s maringe ne1827 MB/s. Iko kumhanya kwekushanda kwekuverenga kwakawedzera muyedzo yekuverenga yakateedzana mu ramdisk (7042 MB/s inopesana ne6849 MB/s) uye kuverenga zvisina tsarukano muNVMe (26 MB/s kupesana ne24 MB/s)
