Linux 6.0 kernel kuburitswa

Mushure memwedzi miviri yebudiriro, Linus Torvalds akapa kuburitswa kweLinux 6.0 kernel. Shanduko yakakosha yenhamba yevhezheni ndeyezvikonzero zvekunaka uye inhanho yakarongeka yekubvisa kusagadzikana kwekuunganidza huwandu hukuru hwenyaya munhevedzano (Linus akaseka kuti chikonzero chekuchinja nhamba yebazi chainyanya kuitika kuti akange achipererwa neminwe. uye zvigunwe kuverenga nhamba dzeshanduro) . Pakati peshanduko dzinonyanya kukosha: tsigiro yeasynchronous buffered kunyora muXFS, ublk block driver, optimization yemugadziri webasa, nzira yekuona mashandiro chaiwo ekernel, rutsigiro rweARIA block cipher.

Makiyi matsva mu kernel 6.0:

  • Disk Subsystem, I/O uye File Systems
    • Iyo XFS faira system yakawedzera rutsigiro rweasynchronous buffered inonyora uchishandisa iyo io_uring mechanism. Maonero ekuita anoitwa uchishandisa maturusi efio (1 shinda, 4kB block size, mazana matanhatu masekonzi, sequential kunyora) inoratidza kuwedzera kwekuita / kubuda kwesekondi (IOPS) kubva 600k kusvika 77k, kufambisa data kubva 209MB / s kusvika 314MB / s, uye kudonha kwe latency kubva ku854ns kusvika ku9600ns (120 nguva).
    • Iyo Btrfs faira system inoshandisa yechipiri vhezheni yeprotocol ye "send" command, iyo inoshandisa rutsigiro rwekuwedzera metadata, kutumira data mumabhuroko makuru (kupfuura 64K) uye kuendesa zviyero mune yakamanikidzwa fomu. Kuita kwekushanda kwekuverenga zvakananga kwakawedzera zvakanyanya (kusvika ku3 nguva) nekuda kwekuverenga panguva imwe chete kusvika kuzvikamu zve256. Yakaderedza kukiyiwa kukakavara uye nekumhanyisa kutarisa kwemetadata nekudzikisa metadata yakachengetwa yezvinhu zvakamisikidzwa.
    • Mashandiro matsva eoctl EXT4_IOC_GETFSUUID uye EXT4_IC_SETFSUUID awedzerwa kune ext4 faira system kuti atore kana kuseta iyo UUID yakachengetwa mu superblock.
    • Iyo F2FS faira sisitimu inopa yakaderera memory yekushandisa modhi, iyo inogonesa kushanda pamidziyo ine shoma shoma ye RAM uye inobvumidza iwe kudzikisa ndangariro kushandiswa pamutengo wekuderedzwa kwekuita.
    • Yakawedzerwa rutsigiro rweNVMe drive kuvimbiswa.
    • Iyo NFSv4 sevha inoshandisa muganho pahuwandu hwevatengi vanoshanda, iyo inoiswa se1024 macustomer anoshanda kune yega gigabyte yeRAM muhurongwa.
    • Kuitwa kwemutengi weCIFS kwakavandudza mashandiro mune akawanda-channel transmission mode.
    • Mureza mutsva FAN_MARK_IGNORE wawedzerwa kuchikamu chekutevera chiitiko mu fanotify FS kuti usazeye zviitiko.
    • MuOverlayfs FS, kana yakakwidzwa pamusoro peFS ine mushandisi ID mepu, rutsigiro rwakakwana rwePOSIX-inopindirana yekuwana yekutonga mazita inopihwa.
    • Yakawedzera ublk block driver, iyo inofambisa chaiyo logic kudivi rekumashure maitiro munzvimbo yemushandisi uye inoshandisa iyo io_uring subsystem.
  • Memory uye system masevhisi
    • Zvinyowani zvakawedzerwa kune iyo DAMON (Data Access MONitor) subsystem, inobvumira kwete chete kutarisa nzira yekuwana RAM kubva munzvimbo yemushandisi, asi zvakare kukanganisa ndangariro manejimendi. Kunyanya, module nyowani "LRU_SORT" yakatsanangurwa, iyo inopa kubatanidzwazve kweLRU (Ichangopfuura Ichangobva Kushandiswa) rondedzero kuwedzera kukosha kwemamwe mapeji endangariro.
    • Iko kugona kugadzira matunhu matsva ekurangarira kwave kushandiswa uchishandisa kugona kwebhazi reCXL (Compute Express Link), rinoshandiswa kuronga kumhanyisa-kumhanya pakati peCPU nemidziyo yekurangarira. CXL inokutendera kuti ubatanidze matunhu matsva ekurangarira anopihwa nekunze ndangariro maturusi uye woashandisa seyekuwedzera kero yenzvimbo zviwanikwa kuti uwedzere sisitimu yekusagadzika ndangariro (DDR) kana yekusingaperi ndangariro (PMEM).
    • Yakagadziriswa nyaya dzekuita ne AMD Zen processors dzakakonzerwa nekodhi yakawedzerwa makore makumi maviri apfuura kuti ishande yakatenderedza nyaya yehardware mune mamwe machipset (imwe yekuwedzera WAIT rairo yakawedzerwa kunonotsa processor kuti chipset ive nenguva yekuenda mune isina basa). Shanduko iyi yakakonzera kudzikiswa kwekuita pasi pemitoro yebasa iyo inowanzochinjana pakati penyika dzisina basa uye dzakabatikana. Semuenzaniso, mushure mekudzima iyo workaround, avhareji tbench bvunzo zvibodzwa zvakawedzera kubva pa20 MB/s kusvika 32191 MB/s.
    • Code ine heuristics yakabviswa kubva kumugadziri webasa, kuve nechokwadi chekutama kwemaitiro kune mashoma akaremerwa maCPU, tichifunga nezve fungidziro yekuwana mukushandiswa kwesimba. Vagadziri vakagumisa kuti iyo heuristic yakanga isingashande zvakakwana uye kuti zvaive nyore kuibvisa uye kutama-tama pasina kumwe kuongorora chero kutama kwakadaro kwaigona kukonzera kuderera kwesimba rekushandisa (semuenzaniso, kana chinangwa cheCPU chiri muchikamu chesimba rezasi). Kuremara heuristics kwakakonzera kudzikiswa kwekushandiswa kwesimba pakuita mabasa akasimba, semuenzaniso, muyedzo yevhidhiyo decoding, kushandiswa kwesimba kwakadzikira ne5.6%.
