Linus Torvalds ya sanar da samuwar sabon sigar Linux Kernel 5.9 a kan jerin aikawasiku Wannan sigar ce wacce ke gabatar da sabbin abubuwa da haɓakawa da yawa, da kuma sabbin direbobi ban da ɗaukakawar direba.
Ci gaban kernel na Linux 5.9 ya fara ne kimanin watanni biyu da suka gabata lokacin da Linus Torvalds ya sanar da matakin farko na Dan Takardar Saki (RC). Bayan kasa da RCs takwas, yanzu akwai sigar karshe ta kwaya kuma yakamata a aika zuwa wasu shahararrun rabon Linux a cikin makonni masu zuwa.
Game da karfi da Linux 5.9, akwai tallafi ga gine-ginen Unicore, goyon baya ga Matsalar Zstandard (Zsdt) don tattara kernels x86, cikakken tallafi ga ayyukan karatu asynchronous buffers a kan io_uring subsystem, tare da sabon zaɓi na ceto da haɓaka abubuwa daban-daban don tsarin fayil ɗin Btrfs.
Akwai kuma - tallafi ga umarnin FSGSBASE x86, damar iyawa don mai tsara lokaci, sabon maɓallin sysctl, goyan bayan ɓoye kan layi don tsarin fayil ɗin EXT4 da F2FS kazalika da tallafi ga masu kula da ƙwaƙwalwar ajiyar waje na NVIDIA Tegra210 da goyan baya ga masu sarrafa abubuwan ciki na Chrome OS.
Har ila yau, Linux 5.9 ya kawo sabon tsarin kira kusa_range (), tallafi ga Intel "Keem Bay" Movidius VPUs, tallafi don yarjejeniya ta rashin daidaituwa, tallafi ga masu yin BPF akan TCP da kwandunan UDP, tallafi don haɓaka halaye don abokan NFS 4.2 da schedutil azaman tsoho mai sarrafa siginar CPU na ARM da AArch64 gine-gine ( ARM64).
Hakanan Isarin tallafi don allon ARM, na'urori da dandamali an haskaka: Pine64 PinePhone v1.2, Lenovo IdeaPad Duet 10.1, ASUS Google Nexus 7, Acer Iconia Tab A500, Qualcomm Snapdragon SDM630 (ana amfani dasu a Sony Xperia 10, 10 Plus, XA2, XA2 Plus da XA2 Ultra), Jetson Xavier NX, Amlogic WeTek Core2 , Aspeed EthanolX, sabbin sabbin kwamitocin NXP i.MX6 guda biyar, MikroTik RouterBoard 3011, Xiaomi Libra, Microsoft Lumia 950, Sony Xperia Z5, MStar, Microchip Sparx5, Intel Keem Bay, Amazon Alpine v3, Renesas RZ / G2H.
Don ƙungiyoyi, ana aiwatar da sabon mai kula da ƙwaƙwalwar slab, wanda yake sananne ne don canja wurin lissafin slab daga matakin shafin ƙwaƙwalwar zuwa matakin kernel, yana ba da damar raba shafukan slab a cikin ƙungiyoyi daban-daban, maimakon rarraba keɓaɓɓun maɓallin keɓaɓɓu don kowane rukunin rukunin. Tsarin da aka gabatar yana ba da damar haɓaka ƙimar amfani da, rage girman ƙwaƙwalwar ajiyar da aka yi amfani da ita don slab ta hanyar 30-45%, yana rage yawan amfani da ƙwaƙwalwar ajiya ta kernel da rage gutsurar ƙwaƙwalwar.
Game da haɓakawa tare da zane-zane, an nuna hakan direban amdgpu yana ƙara tallafin GPU na farko don AMD Navi 21 (Navy Flounder) da Navi 22 (Sienna Cichlid). Ara tallafi don ƙaddamar bidiyo na UVD / VCE da sarrafa injunan haɓaka hanzari na GPUs na Tsibiran Kudancin (Radeon HD 7000). Ara dukiya don juya allo ta digiri 90, 180 ko 270.
Abin sha'awa, direban AMD GPU shine mafi girman direba a cikin kwaya - ya ƙunshi kusan layuka miliyan 2,71 na lambar, wanda yake kusan 10% na jimlar girman kwaya (layuka miliyan 27,81).
A lokaci guda, layuka miliyan 1.79 suna cikin fayilolin taken kai tsaye da aka samar tare da bayanai don rajistar GPU, kuma lambar C itace layuka dubu 366 (idan aka kwatanta, mai sarrafa Intel i915 ya haɗa da layuka dubu 209 da Nouveau - 149 dubu ).
Mai sarrafawa Nouveau yana ƙara tallafi don bincika amincin CRC (Cikakkun undididdigar undididdiga) ta firam akan injunan NVIDIA GPU. Aiwatar da aikin ya dogara ne akan takaddun da NVIDIA ta bayar.
I mana, da yawa sababbi da sabunta direbobi suna cikin wannan sabon sigar mahimmin kwaya don ƙara tallafi don ƙarin sabbin kayan haɗin hardware. Hakanan akwai wasu fasalulluka masu alaƙa da tsaro, da kuma gyaran kura-kuran da aka saba da canjin kwaya na ciki.
A ƙarshe, za a iya sauke wannan sabon sigar daga kernel.org, idan kanaso ka gina kernel naka. Ga waɗansu, kuna iya jiran tsayayyen kern na Linux 5.9 don isa wuraren ajiyayyar software na rarraba GNU / Linux kafin haɓakawa daga sigar da ta gabata.
Dangane da na Linux na gaba 5.10, ana sa ran cewa ya kamata ya isa tsakiyar Disamba ko lokacin hutun Kirsimeti.
