Kernel 4.6 cikakkun bayanai

Daga shekara ta 2015 zuwa shekarar da muke ciki yanzu mun sami ɗaukakawa guda bakwai ko sabbin sigar kernel na Linux. Tafiya daga sigar 3.19, zuwa 4.5. Kamar yadda ake tsammani, a waccan shekarar dole ne mu haɗu da wasu don inganta ainihin, kuma ya kasance. Don wannan watan na yanzu an gabatar da mu da sabon kwafin Linux, a cikin bugunta na 4.6. Ana samun wannan daga 15 ga Mayu, kuma yana ƙara wasu sababbin fasali don tsari ko abun ciki.

Gabaɗaya mun sami ingantaccen sarrafawa daga ƙwaƙwalwar ajiya, tallafi ga USB 3.1 SuperSpeedPlus, tallafi don maɓallan kariya na ƙwaƙwalwar Intel, DA sabon tsarin fayil ɗin OrangeFS da aka rarraba, don kawai kaɗan. Amma a cikin cikakkun bayanai, mahimman abubuwan da aka tattauna game da kwaya sune kamar haka:

  • Dogara daga ƙwaƙwalwa
  • Kernel multiplexer haɗi.
  • Taimako don USB 3.1 SuperSpeedPlus.
  • Taimako don maɓallan kariya na ƙwaƙwalwar Intel.
  • OrangeFS Rarraba Tsarin Fayil.
  • Taimako don sigar V na yarjejeniyar BATMAN.
  • 802.1AE MAC matakin ɓoyewa.
  • Supportara tallafi don shimfidar pNFS SCSI
  • dma-buf: sabon ioctl don gudanar da daidaiton cache tsakanin CPU da GPU.
  • OCFS2 mai duba inode akan layi
  • Taimako don wuraren cgroup

Daga amincin ƙwaƙwalwa.

Wanda ya kashe OOM a cikin sifofin da suka gabata yana da manufar kawar da aiki, tare da fatan cewa za'a kammala wannan aikin a cikin lokaci karɓa kuma daga baya kuma ƙwaƙwalwar za ta sami 'yanci bayan wannan. An nuna cewa yana da sauƙi a ga inda nauyin aiki wanda ya ɓata wannan tunanin yake, kuma wanda aka yi wa OOM zai iya samun lokaci mara iyaka don fita. A matsayin ma'auni don wannan, a cikin sigar 4.6 na kwaya, a oom_raro azaman keɓaɓɓen zaren kwaya, wanda ke ƙoƙarin dawo da ƙwaƙwalwa, ma'ana, don musanya dukiyar wanda aka kama da OOM a waje, ko matakan kariya na ƙwaƙwalwar da ba a sani ba. Duk a ƙarƙashin ra'ayin cewa wannan ƙwaƙwalwar ba za ta zama dole ba.

Kernel multiplexer haɗi.

Kungiyar kernel ta multiplexer tana ba da hanyar haɗi wanda ya dogara da saƙonni akan TCP, tare da manufar saurin ladabi kan ladabi. Kernel mai haɗa multiplexer, ko KCM don ma'anar sunan sa, an haɗa shi don wannan buguwa. Godiya ga kernel mai haɗin multiplexer, aikace-aikace na iya karɓarwa da aika saƙonnin yarjejeniya ta hanyar TCP. Bugu da ƙari, kwaya yana ba da tabbacin cewa an aika saƙonni da karɓar ta atomatik. A gefe guda, kwaya tana aiwatar da mai nazarin saƙo dangane da BPF, duk tare da manufar ana iya karɓar saƙonnin da aka tsara a tashar TCP a cikin kernel mai haɗa multiplexer. Yana da kyau a faɗi cewa ana iya amfani da kwaya mai haɗin multiplexer a cikin aikace-aikace masu yawa, tunda yawancin ladabi na aikace-aikacen binary suna aiki a ƙarƙashin wannan aikin nazarin saƙon.

Taimako don USB 3.1 SuperSpeedPlus (10 Gbps).

Don USB 3.1 an ƙara sabon yarjejeniya; shi SuperSpeedPlus. Wannan yana da ikon tallafawa saurin 10 Gbps. USB 3.1 goyon bayan kernel da mai kula da USB xHCI an haɗa su, wanda ya ƙunshi ɗimbin ajiya, godiya ga haɗin USB 3.1 zuwa tashar USB 3.1 da ke iya ɗaukar xHCI. Ya kamata a lura cewa ana kiran na'urori USB da aka yi amfani dasu don sabuwar yarjejeniya ta SuperSpeedPlus USB 3.1 na'urorin Gen2.

Taimako don maɓallan kariya na ƙwaƙwalwar Intel.

An ƙara wannan tallafi don wani bangare na musamman, yana magana musamman game da kayan aiki da kuma kariya daga ƙwaƙwalwar ajiya wannan. Wannan yanayin zai kasance a cikin Intel CPUs na gaba; makullin kariya. Waɗannan maɓallan suna ba da damar shigar da masks ɗin izini mai amfani zai iya sarrafa su, wanda yake a cikin shigarwar tebur ɗin shafi. Munyi magana game da hakan a maimakon samun tsayayyen abin rufe fuska, wanda ke buƙatar kiran tsarin don canzawa da yin aiki akan kowane shafi, yanzu mai amfani na iya sanya adadin bambance-bambancen daban-daban azaman mask kariya. Game da sararin mai amfani, zai iya ɗaukar batun samun dama cikin sauƙi tare da rajista na gida na zaren, waɗanda aka rarraba su kashi biyu don kowane abin rufe fuska; nakasa samun dama da nakasa rubutu. Da wannan ne muke fahimtar kasancewa ko yuwuwar canza canjin kariya na adadi mai yawa na ƙwaƙwalwar ajiya, kawai tare da gudanar da rajistar CPU, ba tare da buƙatar canza kowane shafi a cikin sararin ƙwaƙwalwar kamala da aka shafa ba.

OrangeFS Rarraba Tsarin Fayil.

LGPL ne ko tsarin ajiyar sikelin-daidaitacce. Ana amfani dashi galibi don matsaloli masu wanzuwa game da ajiyar da aka sarrafa a cikin HPC, Babban Bayanai, yawo bidiyo ko Bioinformatics. Tare da OrangeFS ana iya samun damar ta ta hanyar ɗakunan karatu na haɗin mai amfani, abubuwan haɗin da aka haɗa da su, MPI-IO kuma ana iya amfani da su ta yanayin Hadoop a matsayin madadin tsarin fayil ɗin HDFS.

Don aikace-aikace, OrangeFS ba al'ada ake buƙata a ɗora shi akan VFS ba, amma babban abokin ciniki na OrangeFS yana faruwa ne don ba da tsarin fayiloli damar ɗorawa azaman VFS.

Taimako don sigar V na yarjejeniyar BATMAN.

BATMAN (Ingantacciyar Hanyar Don Sadarwar Sadarwar Wayar hannu) ko TAKARDAR ODI. (Hanya mafi kyau ga hanyoyin sadarwar wayoyin hannu na zamani) Wannan lokacin yana ƙunshe da tallafi don yarjejeniya ta V, azaman madadin yarjejeniya ta IV. Kamar yadda ɗayan mahimman canje-canje a cikin BATMA.NV shine sabon ma'auni, wanda ke nuna cewa yarjejeniyar ba zata ƙara dogara da asarar fakiti ba. Wannan kuma ya raba yarjejeniyar OGM zuwa sassa biyu; na farko shine ELP (Echo Location Protocol), mai lura da kimar hanyar haɗin yanar gizo da kuma gano maƙwabta. Na biyu kuma, sabuwar yarjejeniya ce ta OGM, OGMv2, wanda ya ƙunshi algorithm wanda ke ƙididdige hanyoyin da suka fi dacewa kuma ya faɗaɗa ma'aunin a cikin hanyar sadarwar.

802.1AE MAC matakin ɓoyewa.

Taimako don IEEE MACsec 802.1A, mizanin da ke samar da ɓoye kan Ethernet, an ƙara shi don wannan sakin. Yana ɓoyewa da tabbatar da duk zirga-zirga akan LAN tare da GCM-AES-128. Bugu da kari, kare zirga-zirgar DHCP da VLAN, don haka a guji yin magudi a cikin taken ethernet. An tsara shi don ɗaukar maɓallin ƙara yarjejeniya na MACsec, wanda ya haɗa da rarraba mabuɗan zuwa nodes da rabon tashoshi.

Waɗannan su ne wasu abubuwan da aka inganta a cikin sabon sigar kernel ɗin Linux. Kuna iya ganin cewa an sami cigaba sosai a harkar tsaro. Wanne ne sananne a cikin sabon tallafi da aka haɗe don Compananan Maɗaukaki, tare da girmamawa sosai kan rage kurakurai. Daga cikin fuskoki da dama da aka rufe don wannan sigar 4.6, masu haɓakawa sun tabbatar da cewa zai dace da tsarin da ke haɗe da kwayar Linux da za a sabunta ta atomatik, yana mai yin nuni ga masu rarraba Linux da Android. Wani abu mai mahimmanci a cikin waɗannan tsarin, tunda wannan sabon sigar yayi fice, ta fuskoki da yawa, azaman mafi kyawun kwaya.

Wani ci gaban tsaro shine Linux yanzu yana amfani da shafuka daban daban don Extensible Firmware Interface (EFI) lokacin da yake aiwatar da lambar firmware. Hakanan ya dace da masu sarrafa IBM Power9 kuma yanzu Linux yana da tallafi fiye da tsarin 13 na ARM akan kwakwalwan kwamfuta (SOC) da mafi kyawu 64-bit ARM.

A gefe guda, kernel 4.6 shima yana goyan bayan yarjejeniyar Synaptics RMI4; Wannan ita ce yarjejeniya ta asali don duk abubuwan taɓawar Synaptics na yau da kullun. A ƙarshe, ana ƙara ƙarin tallafi don wasu na'urorin haɗin ɗan adam.

Kernel na Linux yana ƙara ƙarfi idan ya zo ga tsaro. Wani abu mai fa'ida kuma hakan yana haifar da kwarin gwiwa ga masu amfani da ke hade da wannan tsarin kowane lokaci. Idan kuna son ƙarin bayani game da sabon sigar, zaku iya samun damar shafin kernel na Linux ku koya game da canje-canje.


Abubuwan da ke cikin labarin suna bin ka'idodinmu na ka'idojin edita. Don yin rahoton kuskure danna a nan.
