Linux 5.16 yakatoburitswa uye idzi ndidzo nhau dzayo

Chiratidzo Kernel Linux, Tux

Mushure memwedzi miviri yekuvandudza, Linus Torvalds yakafumura kuvhurwa kwe iyo itsva kernel vhezheni ye Linux 5.16 uye ndeipi pakati pekuchinja kunonyanya kukosha ndeye futex_waitv system yekufona yekuvandudza mashandiro eWindows mitambo muWaini, kuteedzera zvikanganiso mufaira refaira kuburikidza ne fanotify, kugona kuchengetedza ndangariro yezvigadziko zvetiweki, kugadzirisa kubata kwekuremerwa ne vhoriyamu hombe yekunyora mashandiro, kutsigirwa kweakawanda-drive hard drive, pakati pezvimwe zvinhu.

Shanduro nyowani yakagamuchira 15415 zvigadziriso kubva kune 2105 vagadziri, shanduko dzakakanganisa gumi nemaviri mafaera., yakawedzera 685198 mitsara yekodhi, yakabviswa 263867 mitsetse.

Inenge 44% yeshanduko dzese dzakaunzwa mu5.16 dzine chekuita nevatyairi vemidziyo, ingangoita 16% yeshanduko ine chekuita nekuvandudza kodhi yakanangana nehardware architecture, 16% ine hukama netiweki stack, 4% ine hukama nemafaira masisitimu uye 4% inoenderana. zvinoenderana nemukati kernel subsystems.

Zvinyorwa zvitsva zveLinux Kernel 5.16

Mune iyi vhezheni itsva iyo mashini inozivisa mamwe maturusi ekutarisa faira system mamiriro uye yekutevera zvikanganiso. Tsigiro yekutevera bug inoitwa parizvino chete yeFS Ext4.

Tambien kubata kwekusangana kwekunyora kwakavandudzwa Izvi zvinoitika kana vhoriyamu yemabasa ekunyora ichipfuura kugona kwedhiraivha uye sisitimu inomanikidzwa kuvharira maitiro ekunyora zvikumbiro kudzamara zvikumbiro zvakatamiswa zvapera.

Mune iyo vhezheni nyowani, iyo kernel nzira inoshandiswa kuwana ruzivo nezve kuitika kwekuremerwa uye kuvharira mabasa yakagadziridzwa zvachose.

Btrfs inoshandisa tsigiro yeZoned Namespace tekinoroji, iyo inoshandiswa mumadhiraivha akaomarara kana NVMe SSDs kugovera nzvimbo yekuchengetera muzvikamu zvinoumba mapoka ezvivharo kana zvikamu, umo chete sequential yekuwedzera yedata inobvumidzwa, uku uchivandudza boka rese rezvivharo.

Nzira yekunyoresa dhairekitori yakagadziridzwa patsva, Imo iyo nhamba yekutsvaga uye kuvhara mumuti yakaderedzwa kuti ivandudze kushanda zvakanaka, kunze kwekuwedzera kutsigirwa kuduku kwekushandisa compression paunenge uchinyora mapeji asina kukwana, pamwe nekukwanisa kukanganisa subpages.

Pamusoro pefaira system Ext4, zvigadziriso zvebug chete zvakaiswa uye kuverengera kwakaringana kweiyo inode tafura ine usimbe kutanga parameters.Payevha yedhijitari level, optimizations yakaitwa iyo inowedzera zvakanyanya kushanda kweiyo link mashandiro kuCPU cores.

Mount sarudzo dzakawedzerwa kuFS F2FS kudzora kupatsanurwa kwemafaira kana achinge achengetwa (semuenzaniso, kugadzirisa zvigadziriso zvekushanda neakakamukana storages).

A new system call yawedzerwa, futex_waitv, yekutarisa mamiriro eakawanda futexes kamwechete nekufona kamwechete system. Ichi chimiro chakafanana neWaitForMultipleObjects mashandiro anowanikwa muWindows, emulation yacho kuburikidza ne futex_waitv inogona kubatsira mukuvandudza mashandiro eWindows mitambo inomhanya paWaini kana Proton.

Mubati akawedzerwa kuTask Scheduler iyo inofunga nezve cache pooling paCPU. Mune mamwe ma processor, akadai Kunpeng 920 (ARM) uye Intel Jacobsville (x86), imwe nhamba yeCPU cores, kazhinji 4, inogona kusanganisa L3 kana L2 cache.

Zvaitwa akati wandei matsva maficha akavakirwa pane iyo DAMON subsystem (Data Access Monitor) yakawedzerwa mune yazvino vhezheni, iyo inobvumira kuteedzera kuwana data mu RAM, zvine chekuita nemaitiro akasarudzwa anomhanya munzvimbo yemushandisi.

Mukuwedzera kune izvi, kushandiswa kweiyo compression algorithm zstd yakagadziridzwa kuita shanduro 1.4.10, izvo zvakaita kuti zvikwanise kuwedzera zvakanyanya kuita kwe akati wandei kernel subsystems anoshandisa compression.

Zvinocherechedzwawo kuti mamwe emhando yepamusoro seccomp () tambo yekudzivirira nzira kurwisa Specter kurwiswa akaremara nekusagadzika, ayo aionekwa seasina basa uye haana kunyanya kuwedzera chengetedzo, asi aine kukanganisa kwekuita.

Iyo Hyper-V hypervisor ikozvino inotsigira chaiwo muchina wekuparadzanisa modhi, iyo inovhara zviri mukati mendangariro.

Panguva iyo hypervisor KVM inowedzera tsigiro yeRISC-V yekuvakisa uye kugona kufambisa machina chaiwo mukati menzvimbo yekugamuchira yakashandiswa uchishandisa AMD SEV uye SEV-ES edzedzero, pamwe neakawedzera API yekutama kunogara kwe AMD SEV (Yakachengetedzwa Encrypted Virtualization) yakavharirwa vashanyi.

Kune iyo PowerPC architecture, iyo STRICT_KERNEL_RWX modhi inogoneswa neyakagadzika, iyo inovhara kushandiswa kwemapeji ekurangarira anowanikwa panguva imwe chete kunyora nekuita.

Pakupedzisira kune chikamu chevatongi, amdgpu inosuma yekutanga rutsigiro rweDP 2.0 (Ratidza Port 2.0) uye DisplayPort tunneling kuburikidza ne USB4, yakawedzera kuratidza mutyairi rutsigiro rwe APU Cyan Skillfish uye yakawedzera rutsigiro rwe APU Yellow Carp.

Mutungamiriri i915 inodzikamisa kuenderana neIntel Alderlake S chips uye inoshandisa tsigiro yeIntel PXP (Yakachengetedzwa Xe Path) tekinoroji, iyo inoita kuti iwe ugone kugamuchira yehardware-yakadzivirirwa giraidhi chikamu pane masisitimu ane Intel Xe chips.

Mu controller nouveau, basa raitwa kugadzirisa tsikidzi uye kuvandudza maitiro ekukodha, yakawedzera rutsigiro rwex86 inoenderana Vortex CPU (Vortex86MX).

Finalmente kana iwe uchifarira kuziva zvakawanda nezvazvo, unogona kutarisa ruzivo mu inotevera chinongedzo.

Kana zviri zvekuvandudzwa kweiyi vhezheni nyowani, vanofanirwa kunge vachisvika mukati memaawa / mazuva mumatanho epamutemo ekugovera kwako kana iwe unogona kusarudza kuita kuunganidzwa iwe pachako nekuwana iyo kodhi kodhi. kubva pane iyi link iripazasi.


Izvo zviri muchinyorwa zvinoomerera pamisimboti yedu ye tsika dzekunyora. Kuti utaure chikanganiso tinya pano.

Iva wekutanga kutaura
