Ngemuva kwezinyanga ezimbili zentuthuko, inguqulo entsha yeLinux Kernel 5.4 yethulwe, inguqulo lapho kuguqulwa izinguquko ezahlukahlukene Lokhu kufaka phakathi: umshayeli we-exFAT wokuhlola, imodi "yokukhiya" ukukhawulela ukufinyelela kwezimpande ku-kernel, indlela ye-fs-verity yokuqapha ubuqotho befayela, ikhono lokusebenzisa i-CIFS ukwahlukanisa izimpande, nokuningi.
Uhlobo olusha lwamukele isichibi sika-15743s, usayizi wepatch ungama-63MB (ushintsho luthinte amafayela ayi-12800 828167, imigqa yekhodi engu-126149 ingeziwe, kususwe imigqa engu-46). Cishe u-5.4% wazo zonke izinguquko ezethulwe ku-15 zihlobene nezishayeli zedivayisi, cishe u-12% wezinguquko uhlobene nokuvuselela ikhodi ethile yezakhiwo zehadiwe, i-4% ihlobene nesitaki senethiwekhi, i-3% enezinhlelo zamafayela ne-XNUMX% ngezinsizakusebenza zangaphakathi ze-kernel.
Izici ezintsha eziyinhloko zeLinux 5.4
Esigabeni sokuhlola «isiteji» ("Abashayeli / isiteji /"), lapho izinto ezidinga ukucwengwa zibekwa khona, umshayeli we-exFAT ovulekile owenziwe yi-Samsung uyangezwa. Phambilini, bekungenzeki ukwengeza ukuxhaswa kwe-exFAT ku-kernel ngenxa yamalungelo obunikazi, kepha isimo sishintshile ngemuva kokuthi iMicrosoft ikhiphe imininingwane etholakala esidlangalaleni futhi yavumela amalungelo obunikazi e-exFAT ukuthi asetshenziswe mahhala ku-Linux.
Umshayeli ongezwe ku-kernel usekelwe kwikhodi ye-Samsung ingasasebenzi (inguqulo 1.2.9), edinga ukulungiswa nokuzivumelanisa nezidingo zokuklama ikhodi ye-kernel.
Kungezwe indlela yokuthola ukulungiswangakho ukufaka esikhundleni fs-verity, efana ne-dm-verity, kepha isebenza ezingeni lohlelo lwefayela, hhayi kudivayisi yokuvimba. I-Fs-verity ingeza ikhono lokukhetha ukukhetha ubuqotho nokuqinisekisa amafayela ngamanye asetshenziswe kumodi yokufunda kuphela.
Isishayeli esisha se- "Device-Mapper dm-clone" ifinyelela ku-Linux kernel 5.4, lokhu ikuvumela ukuthi wakhe ikhophi lendawo ngokususelwa kudivayisi yokufunda kuphela lokho kungabhalwa ngesikhathi senqubo yokwakha.
Uhlelo lwefayela le-EROFS ebelikade lisegatsheni "lesiteji" seluhanjiswe esihlahleni esikhulu.
I-EROFS isekela ukugcina idatha ecindezelweyo, kepha ithatha indlela ehlukile yokugcina amabhulokhi acindezelwe, alungiselelwe ukusebenza okuphezulu ngokufinyelela okungahleliwe kwedatha.
Engxenyeni ebonakalayo, i-kernel yamukele imodyuli engu- »lockdown», okubandakanya iziqeshana ezinikezwe ukwabiwa, okusetshenziselwa ukukhawulela ukufinyelela komsebenzisi wezimpande ku-kernel nokuvimba ukudlula kwe-UEFI Secure Boot.
Ngaphandle kokusebenzisa ukukhiya, umhlaseli ophumelela ukwenza ikhodi ngamalungelo ezimpande angenza futhi ikhodi yakhe ezingeni le-kernel, ngokwesibonelo ngokufaka esikhundleni se-kernel nge-kexec noma imemori yokufunda / yokubhala nge / dev / kmem.
Enye into entsha ukuthi ingeziwe isistimu yefayela yama-virtiofs amasha, enika amandla ukuthekelisa okusebenzayo kwezingxenye zohlelo lwefayela kusuka kusistimu yokubamba kuya ezinhlelweni zezivakashi. Umkhombandlela omakwe ukuthekelisa ungafakwa ngohlelo lwezivakashi ohlangothini lomsingathi, olwenza kube lula kakhulu ukuhlelwa kokufinyelela okwabiwe kuzikhombisi ezinhlelweni zokwenza izinto.
Ngakolunye uhlangothi, kuvela ukuthi I-Amdgpu ingeza ukusekelwa kwamaNavi 12/14 GPUskanye ne-Arcturus ne-Renoir APUs, kufaka phakathi amathuluzi okuphatha amandla eNavi12, Renoir, ne-Arcturus.
Isilawuli amdkfd (kuma-GPU ahlukile njengeFiji, iTonga, iPolaris) kungezwe ukusekelwa kwamakhadi asuselwa kumaNavi14, Navi12 kanye ne-Arcturus GPUs.
Kumshayeli we-DRM wamakhadi emidwebo ye-Intel, ukuxhaswa kwe-GPU okusetshenziswe kuma-chips angakakhishwa kungeziwe ngokuya ngobuchwepheshe obusha beTiger Lake.
Isistimu esephansi ye-DRM (Direct Rendering Manager) kanye nomshayeli we-i915 DRM wohlelo olungaphansi lwevidiyo ye-Intel bangeze ukusekelwa kobuchwepheshe bokuvikela ikhophi yevidiyo ye-HDCP2.2.
Umshayeli weNouveau wenze ngcono ukuphathwa kombala wokubonisa futhi ungeze amandla wokusebenzisa izakhiwo ezingeziwe (i-DEGAMMA / CTM / GAMMA) yeNVIDIA nv50 GPU.
Ngenkathi i-hardware:
- Kungezwe usekelo lwe-ARM SoC ASpeed AST2600.
- Ukusekelwa kweKendin / Micrel / Microchip SoCs esephelelwe yisikhathi futhi engasasetshenziswa, iWinbond / Nuvoton W8695x90, ne-Intel IOP900x / IOP33xx zisusiwe.
- Ukwesekwa okungeziwe kwamapulatifomu namapuleti 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, AOp Mini, Aen Mini, I-Chromebase Mini AST2600, Leez RK3399 P710.
- Kungezwe ukusekelwa kwama-laptops ngokususelwa ku-SoC Snapdragon 835 / MSM8998 (Asus NovaGo TP370QL, HP Envy X2 neLenovo Miix 630), i-Snapdragon 850 / sdm850 (Lenovo Yoga C630) kanye nama-smartphones asuselwa ku-Snapdragon 410 / MSM8916 (Samsung Galaxy A3, A5, Longcheer L8150 / Android One 2).
