Bayan watanni biyu na ci gaba, Linus Torvalds ya gabatar da fitowar Linux Kernel 5.0. A lokaci guda, Gidauniyar Free Software ta Latin Amurka ta kirkiro Kernel 5.0 mai cikakken kyauta: Linux-libre 5.0-gnu, ba tare da abubuwan firmware ko direbobin da ke ƙunshe da abubuwan da ba na kyauta ba ko ɓangarorin lambar, wanda masana'antar ke iyakance ikonta.
tsakanin mafi shaharar sauye-sauye a cikin Kernel 5.0 shine ƙari na babban ARM na Android.LITTLE CPU Task Scheduler, Adiantum fayil tsarin ɓoyayyen tsari, Tallafin fasaha na FreeSync a cikin direban AMDGPU da ƙari mai yawa.
Babban sabon labari na Kernel 5.0
Daga cikin sanannun canje-canje a cikin Kernel 5.0 zamu sami ƙari na tsarin ɓoye fayil na Adiantum fayil wanda Google ya haɓaka, wanda za'a iya amfani dashi a cikin ƙananan na'urori masu ƙarfi wanda, saboda yawan obalodi, bazai iya amfani da algorithm na ɓoye AES ba.
Aiwatar da Adiantum ya dogara da yin amfani da aikin hash mai sauri na NH, Poly1305 (MAC) algorithm na tabbatar da saƙo, da XChaCha12 ɓoye ɓoyekazalika da aiki guda daya wanda ya danganci boye-boye AES-256 na baiti 16 a cikin kowane toshe.
An ƙara Adiantum zuwa ƙaramin tsarin fscrypt, wanda ake amfani dashi don ɓoye fayiloli da kundayen adireshi akan ext4, f2fs, da ubifs tsarin fayil.
Wani fasalin da zamu iya haskakawa daga wannan sakin shine direban AMDGPU wanda ya ƙara tallafi don fasahar daidaita aiki ta FreeSync (VESA Adaptive-Sync), wanda ke ba ku damar daidaita yanayin shakatawa na bayanin akan allon saka idanu don tabbatar da ƙaramar lokacin amsawa, fitarwa mai sauƙi, kuma babu tsangwama yayin wasanni da bidiyo.
FreeSync yana ba ka damar rage amfani da wuta ta hanyar rage ƙarfin wartsakewa yayin da hoton da ke kan allon bai canza ba.
An kara goyan baya don shirye-shiryen ƙwaƙwalwar NVM a cikin wannan sakin Kernel 5.0 tare da ayyukan tsaro kamar su kariya ta sirri, tsaftacewa da kullewa.
Haɗa ɓangaren ɓangaren faci don toshe ɓoyo da gujewa iyakokin amintaccen Boot.
A wannan matakin, an ƙara kayan aikin don sarrafa amfani da kexec_load_file () tsarin kira, wanda za a iya amfani da shi don ƙetare amintaccen boot na UEFI ta maye gurbin Kernel ɗin da aka gwada tare da wani Kernel wanda ba a sa hannu a cikin lambobi ba.
Tsarin diski, I / O, da tsarin fayil
Abilityara ikon sanya swap bangare zuwa fayiloli cikin tsarin fayil ɗin Btrfs. Dole ne fayil ɗin saƙo a cikin Btrfs ya zama cikakke a cikin yanayin "nocow" ba tare da yin amfani da matsewa ba kuma a ɗora shi a kan tuki ɗaya kawai.
Tsarin hanyar sadarwa
Don UDP, ana iya aiwatar da ikon aika bayanai zuwa soket ɗin hanyar sadarwa a yanayin kwafin sifili (aika kira tare da tutar MSG_ZEROCOPY), wanda ke ba da damar canja wurin bayanai akan hanyar sadarwar ba tare da tsaka-tsakin tsaka-tsakin ba.
Jigon UDP yana aiwatar da tallafi na GRO na asali (Generic Receive Offload) don saurin aiwatar da adadi mai yawa na fakiti masu shigowa, ƙara fakitoci da yawa a cikin manyan bulodi waɗanda basa buƙatar aiki daban na kowane fakiti.
Memorywa memorywalwar ajiya da sabis
An aiwatar da sabon yanayin tsara jadawalin aiki don masu sarrafa ARM na asymmetric dangane da babban.LITTLE architecture, wanda ya haɗu da ƙarfi, amma mai cin wuta sosai, ƙwayoyin CPU da ƙarancin fa'ida, amma mafi ƙarancin ƙarfi.
Sabuwar yanayin zai yana ba da damar rage yawan amfani da wuta saboda ayyukan farkawa galibi akan abubuwan CPU.
A gefe guda, an ƙara tallafi don umarnin WBNOINVD umarnin, wanda aka aiwatar a cikin AMD da masu sarrafa Intel bisa ga gine-ginen x86_64. Bayanin da aka ƙayyade yana rajistar duk tashoshin ɓoye a kowane matakan ƙungiyoyin ɓoye tare da babban ƙwaƙwalwar ajiya, yayin adana ƙimar ɓoye a cikin cache.
Yadda ake samun Kernel 5.0?
Ana samun Kernel 5.0 don zazzagewa kai tsaye daga kernel.org idan kanaso ka hada shi da kanka.
Kodayake hakan zai kasance a cikin rarrabawar Linux a cikin kwanaki masu zuwa.
