Kadib laba bilood oo horumar ah, nooca cusub ee Linux Kernel 5.4 ayaa la soo bandhigay, nooca ku jira isbedelada kala duwan ayaa lagu muujiyey Kuwaas waxaa ka mid ah: Darawalka tijaabada ah ee exFAT, qaabka "qufulka" si loo xaddido marin u helidda xididka geedka, fs-runta farsamaynta si loola socdo hufnaanta faylka, awoodda loo adeegsan karo CIFS qaybta xididka, iyo inbadan.
Nooca cusub wuxuu qaatay 15743 patchs, balastarka cabirkiisu waa 63MB (isbeddelada saameeyay faylasha 12800, khadadka 828167 ee koodhka lagu daray, 126149 Khadadka waa laga saaray). Qiyaastii 46% dhammaan isbeddelada lagu soo bandhigay 5.4 waxay la xiriiraan wadayaasha aaladda, qiyaastii 15% isbeddelada waxay la xiriiraan cusbooneysiinta koodhka gaarka ah ee qaab dhismeedka qalabka dhismaha, 12% waxay la xiriiraan xirmooyinka shabakadda, 4% oo leh nidaamyada faylka iyo 3% oo leh nidaamyo hoose oo kernel ah.
Astaamaha ugu muhiimsan ee cusub ee Linux 5.4
Qeybta tijaabada ah ("Darawallada / istish-haadka /"), halka lagu dhejiyo qaybaha u baahan in la sifeeyo darawal furan oo loo yaqaan 'exFAT' oo ay soo saartay shirkadda Samsung ayaa lagu daray. Markii hore, suurtagal ma ahayn in lagu daro taageerada 'exFAT' kernel sababo la xiriira shatiyada, laakiin xaaladdu way is beddeshay ka dib markii Microsoft ay sii deysay qeexitaanno la heli karo oo furan oo loo oggolaaday shatiyada exFAT in loogu isticmaalo bilaash Linux.
Darawalka lagu daro kernel wuxuu ku saleysan yahay lambar Samsung ah duugoobay (nooca 1.2.9), oo u baahan turxaan bixin iyo la qabsi shuruudaha loo qaabeeyo nambarka xarkaha.
Waxaa lagu daray farsamo lagu ogaado isbaddeladasidaas bedel fs-verity, oo la mid ah dm-verity, laakiin ka shaqeeya heerka faylasha, kuma jiraan qalabka xannibista. Fs-verity waxay ku dareysaa awooda xulashada adeegsiga jeegaga sharafta iyo xaqiijinta feylasha shaqsiyeed ee loo isticmaalo qaabka kaliya-akhriska.
Darawal cusub oo ah "Device-Mapper dm-clone" cusub gaadho Linux kernel 5.4, tan wuxuu kuu ogolaanayaa inaad sameysato nuqul maxalli ah oo ku saleysan aaladda wax aqriska kaliya aqrisan karta taas waa la qori karaa inta lagu jiro hawsha dhejinta
Nidaamka faylka 'EROFS' ee horay ugu jiray laanta "staging" waxaa loo wareejiyay geedka weyn.
EROFS waxay taageertaa keydinta xogta la adkeeyay, laakiin waxay qaadaysaa habab ka duwan sidii loo kaydin lahaa baloogyada la isku adkeeyay, oo loo habeeyay waxqabadka sare ee helitaanka xogta si aan kala sooc lahayn
Qeybta hufnaanta, firirku wuxuu qaatay "moduleka" qufulka », kaas oo ku darsaday balastarrada lagu bixiyay qaybinta, loo isticmaalay in lagu xaddido marin u helka isticmaalaha asalka ah ee kernel-ka iyo in laga hortago marinka Bootada 'UEFI Secure Boot'.
Adigoon isticmaalin qufulka, weeraryahan ku guuleysta inuu fuliyo koodh leh mudnaanta aasaasiga ah wuxuu sidoo kale fulin karaa lambarkiisa heerka kernel, tusaale ahaan isagoo ku beddelaya kernel kexec ama akhrinta / qorista xusuusta via / dev / kmem.
Cusboonaysiin kale ayaa ah in lagu daray nidaam feylasiyaal cusub ah, taas oo awood u siinaysa dhoofinta hufan ee qaybaha nidaamka faylasha nidaamka martida loo yahay nidaamyada martida. Tusaha loo calaamadeeyay dhoofinta waxaa lagu dhejin karaa nidaamka martida ee dhinaca martida loo yahay, taas oo si weyn u fududeyneysa abaabulka marin wadaagga marinnada nidaamyada hab-dhaqameedka.
Dhinaca kale, way ka muuqataa taas Amdgpu wuxuu ku darayaa taageerada Navi 12/14 GPUssidoo kale Arcturus iyo Renoir APUs, oo ay ku jiraan aaladaha maareynta awooda ee Navi12, Renoir, iyo Arcturus.
Maamulaha amdkfd (loogu talagalay GPU-yada sida Fiji, Tonga, Polaris) ku daray taageerada kaararka ku saleysan Navi14, Navi12 iyo Arcturus GPUs.
Darawalka DRM ee kaararka naqshadeynta Intel, taageerada GPU ee loo adeegsaday jajabyo aan wali la sii deyn ayaa lagu daray iyadoo lagu saleynayo microarchitecture cusub ee Tiger Lake.
Nidaamka hoose ee 'DRM' (Direct Rendering Manager) iyo darawalka i915 DRM ee nidaamka fiidiyowga ee 'Intel video' ayaa ku darsaday taageerada HDCP2.2 fiidiyowga iyo teknolojiyadda ilaalinta nuqulka maqalka ah.
Darawalka Nouveau wuxuu hagaajiyay maaraynta midabka muuqaalka waxayna ku darsatay awooda adeegsiga guryaha dheeraadka ah (DEGAMMA / CTM / GAMMA) ee loogu talagalay NVIDIA nv50 GPU.
Halka qalabka:
- Taageero lagu daray ARM SoC ASpeed AST2600.
- Taageerada waqtigii duugga ahaa ee aan dib loo isticmaalin Kendin / Micrel / Microchip SoCs, Winbond / Nuvoton W8695x90, iyo Intel IOP900x / IOP33xx ayaa laga saaray.
- Taageero dheeraad ah oo loogu talagalay dhufto iyo taarikada 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, A Mini, Chromebase Mini AST2600, Leez RK3399 P710.
- Taageero lagu daray kombuyuutarrada gacanta oo ku saleysan SoC Snapdragon 835 / MSM8998 (Asus NovaGo TP370QL, HP Envy X2 iyo Lenovo Miix 630), Snapdragon 850 / sdm850 (Lenovo Yoga C630) iyo taleefannada casriga ah ee ku dhisan Snapdragon 410 / MSM8916 (Samsung Galaxy A3, A5, Longcheer L8150 / Android One) 2).
