Linux Kernel
An saki ingantaccen sigar Linux kernel 5.0 ga jama'a jiya, Duk da yake gabaɗaya canzawa zuwa lambar sigar daban daban a cikin gudanar da rayuwa ta rayuwa yawanci yana nufin ƙara manyan haɓakawa zuwa sabon sigar da aka fitar, wannan ƙa'idar ba ta sami matsayinta a cikin sabon sigar kwaya ta 5.0 Linux ba wacce ke yanzu.
A cewar Linus Torvalds, wannan lambar "5.0" da aka sanya «ba komai bane face gaskiyar cewa lambobin 4.x sun sami girma sosai wanda ya sa na bar ba tare da yatsu da yatsu ba". A sauƙaƙe, kawai "bushe-bushe".
Duk da haka, lambar sabuwar sigar kwayar Linux ba ta bin takamaiman doka kuma ba ta yin komai sai dai ta farantawa Linus rai.
A cikin wannan babban juzu'in na Linux Kernel, ya zo tare da gudanar da aikin ingantaccen makamashi akan na'urorin tarho ta hanyar mai tsara aiki.
Menene sabo a cikin Linux 5.0 Kernel?
Wannan sabon tsarin tsara makamashi mai inganci damar mai tsara aiki ya yanke shawarar hakan rage yawan amfani da wuta akan dandamali na SMP na asymmetric, kamar farkon kunnawa na ayyuka zuwa mafi sarrafa makamashi mai sarrafawa.
Wannan yana da mahimmanci saboda, a aikace, yana samar da kyakkyawan ikon sarrafawa don wayoyi masu amfani da manyan ARM.LITTLE masu sarrafawa.
Har yanzu a matakin na'urar adana wutar lantarki, an sami ci gaba a cikin sarrafa tsarin tsarin fayil na Linux.
Wannan sabon sigar Kernel 5.0 yana ƙara tallafi don Adiantum, tsarin ɓoyewa daban da algorithm na AES.
Adiantum an kirkire shi ne don samar da tsarin ɓoye fayil a kan ƙananan na'urori na Android waɗanda ba su da ɓoyayyen ɓoyayyen Maƙallan Asali (AES).
Wannan yana da fa'ida sabodae akan ARM Cortex-A7, Adiantum ɓoye don saƙonni 4096-byte kusan sau 4 fiye da ɓoyayyen AES-256-XTS kuma yanke hukunci ya ninka na karshen sau kusan 5.
Hakanan direbobin bidiyo sun sami ci gaba
Baya ga waɗannan siffofin biyu don na'urori masu amfani da makamashi, Wannan sigar ta 5.0 na kwayar Linux ta haɗa da tallafin AMD na FreeSync.
A cewar wasu masu amfani, FreeSync shine mafi mahimmancin fasalin AMDGPU wanda aka sake shi.
FreeSync fasaha ce ta daidaita aiki tare don nunin LCD wanda ke tallafawa saurin wartsakewa don samar da ƙarancin ikon latency da ƙwarewar kallo mai kyau.
Tare da sigar 19.0 na ɗakin karatun Mesa3D, Linux Kernel 5.0 na iya tallafawa FreeSync / VESA Adaptive-Sync akan duk haɗin DisplayPort. Wannan fasalin da ya ɓace daga direban AMD Linux yanzu yana nan.
Kamar sauran haɓakawa, wannan sabon sigar kwayar Linux har ila yau ya haɗa da tallafi ga mai kula da albarkatun cpuset a cikin cgroupv2, sabon tsarin haɗin gwiwar sarrafa Linux.
Direban cpuset yana ba da wata hanyar don ƙayyade wurin mai sarrafawa da ayyukan kumburi ƙwaƙwalwa don kawai albarkatun da aka ƙayyade a cikin fayilolin ƙungiyar sarrafawa ta CPU mai aiki a yanzu.
Daga cikin ci gaban da aka gabatar a cikin sabon kernel na Linux 5.0, yanzu Hakanan zamu iya ambaci goyon bayan fayilolin musanya a cikin Btrfs.
Shekaru da yawa, tsarin fayil na Btrfs ya kawar da tallafin fayil ɗin musanya saboda yiwuwar rashawa.
Duk da haka, Yanzu da cewa an sanya ƙuntatawa masu dacewa, masu kula da kwaya sun dawo da tallafi don sauya fayiloli akan tsarin fayil ɗin Btrfs. Kuma don yin wannan, dole ne a sanya fayil ɗin saƙo gaba ɗaya azaman "nocow" ba tare da matsi akan na'urar da ake magana ba.
A ƙarshe, muna da ƙari na binderfs, tsarin fayil ɗin karya don mai sarrafa Android Binder IPC. Wannan tsarin fayil ɗin da ke ɗaure yana ba ku damar gudanar da lokuta da yawa na Android.
Bayan wadannan mahimman ci gaban, muna kuma da sabbin direbobi da yawa da sauran kayan haɓakawa waɗanda suka haɗa da tsarin fayil, gudanar da ƙwaƙwalwar ajiya, layin toshewa, ƙwarewa, ɓoyewa, hanyar sadarwa, X86, ARM, PowerPC, RiscV gine-ginen, direbobi, da dai sauransu.
Yadda ake girke Kernel 5.0?
Idan kuna sha'awar girka wannan sabon fasalin Kernel, Kuna iya ziyartar mahaɗin mai zuwa inda muke gabatar da hanyoyi biyu don yin sa. Haɗin haɗin shine wannan.
