Emva kweenyanga ezimbini zophuhliso, Inguqulelo entsha yeLinux Kernel 5.4 ibonisiwe, uguqulelo apho utshintsho olwahlukeneyo lubonakalisiwe Oku kubandakanya: uvavanyo lomqhubi we-exFAT, indlela "yokutshixa" yokunciphisa ukufikelela kweengcambu kwi-kernel, fs-verity mechanism yokujonga ukuthembeka kwefayile, ukukwazi ukusebenzisa i-CIFS kulwahlulo lweengcambu, kunye nokunye.
Inguqulelo entsha eyamkelweyo ngo-15743s, ubungakanani bepatch ngu-63MB (utshintsho oluchaphazele iifayile ezili-12800, imigca engama-828167 yekhowudi yongezwa, imigca eli-126149 isusiwe). Malunga ne-46% yazo zonke iinguqu ezinikiweyo ku-5.4 zinxulumene nabaqhubi bezixhobo, malunga neepesenti ezili-15 zotshintsho zinxulumene nokuhlaziya ikhowudi ethile yoyilo lwehardware, i-12% inxulumene nesitaki senethiwekhi, iipesenti ezi-4 kunye neefayile kunye ne-3% ngenkqubo yangaphakathi yekernel.
Iimpawu ezintsha eziphambili zeLinux 5.4
Kwicandelo lokulinga «lokulinganisa» ("Abaqhubi / iistage /"), apho izinto ezifuna ukucokiswa zibekwe khona, umqhubi we-exFAT ovulekileyo ophuhliswe yi-Samsung uyongezwa. Ngaphambili, bekungekho lula ukongeza inkxaso ye-exFAT kwikernel ngenxa yamalungelo awodwa omenzi wechiza, kodwa imeko yatshintsha emva kokuba uMicrosoft ekhuphe iinkcukacha ezikhoyo esidlangalaleni kwaye wavumela amalungelo abenzi e-exFAT ukuba asetyenziswe simahla kwiLinux.
Umqhubi ongezwe kwikernel usekwe kwikhowudi ye-Samsung iphelelwe lixesha (inguqulelo 1.2.9), efuna ukucokiswa kunye nokulungiswa kwiimfuno zokuyila ikhowudi yekernel.
Yongeze indlela yokufumana uhlengahlengisoendaweni yoko fs-verity, efanayo dm-verity, kodwa usebenza kwinqanaba lefayile, hayi kwisixhobo sebhloko. Ubunyani be-Fs bongeza amandla ekusebenziseni ukukhetha ukukhangela ukuthembeka kunye nokuqinisekisa iifayile ezizodwa ezisetyenziswa kwimowudi yokufunda kuphela.
Umqhubi omtsha "weSixhobo-seMephu se-dm-clone" ifikelela kwi-Linux kernel 5.4, le ikuvumela ukuba wenze ikopi yendawo ngokubhekisele kwisixhobo sebhloko sokufunda kuphela ezinokubhalwa ngexesha lenkqubo yokwenza izinto.
Inkqubo yefayile ye-EROFS eyayifudula isesebeni "sokuqokelela" isiwe kumthi ophambili.
I-EROFS ixhasa ukugcina idatha ecinezelweyo, kodwa ithatha indlela eyahlukileyo yokugcina iibhloko ezixineneyo, ezilungiselelwe ukusebenza okuphezulu ngokufikelela ngokungacwangciswanga kwedatha.
Kwinxalenye yokubona, i-kernel yamkele imodyuli yokutshixa », ezibandakanya iziqwengana ezinikezelweyo kulwabiwo, ezisetyenziselwa ukuthintela ukufikelela komsebenzisi wengcambu kwikernel kunye nokubhloka kwe-UEFI Secure Boot bypass.
Ngaphandle kokusebenzisa ukutshixa, umhlaseli ophumeleleyo ekwenzeni ikhowudi kunye namalungelo engcambu angenza kwakhona ikhowudi yakhe kwinqanaba le-kernel, umzekelo ngokutshintsha i-kernel nge-kexec okanye imemori yokufunda / yokubhala nge / dev / kmem.
Enye into entsha kukuba yongezwa inkqubo yefayile ye-virtiofs entsha, esenza ukuba ukuthunyelwa ngokukuko kweefayile zenkqubo yefayile ukusuka kwinkqubo yokubamba ukuya kwiinkqubo zeendwendwe. Ulawulo oluphawulwe ngokuthumela kwelinye ilizwe lunokuxhonywa kwinkqubo yeendwendwe kwicala lomamkeli, nto leyo eyenza kube lula ukwenza umbutho wofikelelo ekwabelwana ngalo kwizikhombisi ezikwiinkqubo zokubona.
Kwelinye icala, kuyacaciswa ukuba I-Amdgpu yongeza inkxaso yeNavi 12/14 GPUskunye neArcturus kunye neRenoir APUs, kubandakanya izixhobo zolawulo lwamandla eNavi12, iRenoir, kunye neArcturus.
Umlawuli amdkfd (kwii-GPUs ezahlukeneyo njengeFiji, iTonga, iPolaris) yongezwe inkxaso yamakhadi asekwe kwiNavi14, Navi12 kunye neArcturus GPUs.
Kumqhubi we-DRM wamakhadi emizobo ye-Intel, inkxaso ye-GPU esetyenzisiweyo kwiichips engekakhutshwa iye yongezwa ngokusekwe kuyilo olutsha lweTiger Lake.
Inkqubo esezantsi ye-DRM (i-Direct Rendering Manager) kunye nomqhubi we-i915 DRM wesixokelelwano sevidiyo se-Intel bongeze inkxaso yevidiyo ye-HDCP2.2 kunye nomxholo wetekhnoloji yokukhusela ikopi.
Umqhubi weNouveau uphucule ukulawulwa kombala kwaye yongeze amandla okusebenzisa iipropathi ezongezelelweyo (i-DEGAMMA / CTM / GAMMA) yeNVIDIA nv50 GPU.
Ngelixa izixhobo zekhompyutha:
- Yongezwe inkxaso ye-ARM SoC ASpeed AST2600.
- Inkxaso yokuphelelwa lixesha kwaye ayisasebenzi Kendin / Micrel / Microchip SoCs, Winbond / Nuvoton W8695x90 kunye ne-Intel IOP900x / IOP33xx isusiwe.
- Inkxaso eyongezelelweyo yeqonga kunye neepleyiti I-ARM Snapdragon 855 (SM8150), Mediatek MT7629, Allwinner V3, NXP i.MX8M Nano, Layerscape LS1046A, Amlogic SM1 (S905X3), Amlogic G12B (S922X, A311D), Rockchips Mecer Xtreme Mini S6, AO Mini Mini I-Chromebase Mini AST2600, iLeez RK3399 P710.
- Inkxaso eyongeziweyo yeelaptops isekwe kwi-SoC Snapdragon 835 / MSM8998 (Asus NovaGo TP370QL, HP Envy X2 kunye neLenovo Miix 630), Snapdragon 850 / sdm850 (Lenovo Yoga C630) kunye nee-smartphones ezisekwe kwi-Snapdragon 410 / MSM8916 (Samsung Galaxy A3, A5, Longcheer L8150 / Android One 2).
