Linux inonyanya mahara kernel yakafanana neiyo Unix kernel.Ndiyo mumwe wemienzaniso mikuru yemahara uye yakavhurika sosi software.
Linus Torvalds akapa kuburitswa kweLinux Kernel 6.8, iyo inosvika mushure memwedzi miviri yebudiriro uye pakati pekuchinja kunonyanya kukosha kwekuburitswa uku kuwedzera kwemutyairi weXe weIntel GPUs, nzira itsva yekudzivirira yemidziyo yekuvhara, kuisirwa kweiyo Deadline server basa rekuronga mashandiro, otomatiki optimization yekubatanidza zvakafanana. mapeji endangariro, pakati pezvimwe zvinhu.
Iyo Linux 6.8 kernel inopa nhevedzano yebudiriro huru inobata zvinhu zvakasiyana-siyana, kubva pakuita uye kuchengetedzeka kusvika pakuenderana nehardware uye zvivakwa. Iko kuburitswa kunosanganisira 15,641 dhizaini inogadzirisa, ine chigamba saizi ye44 MB. Shanduko idzi dzakanyanya kutariswa pamadhiraivha emidziyo uye kodhi yekuvandudza yezvivakwa zvehardware.
Main nyowani maficha eLinux 6.8
Pakati pezvinonyanya kuvandudzwa zveiyi vhezheni itsva yeLinux Kernel 6.8 ndiyo disk subsystem, I/O uye mafaera masisitimu, uko. shanduko dzakaitwa kuvharira kunyora kwakananga kune akaiswa block zvishandiso (nekusagadzika, iyo modhi inovharwa uye inoda iyo BLK_DEV_WRITE_MOUNTED parameter kuti itsanangurwe pakugadzira), pamwe chete new system inoda ruzivo rwakadzama pane akaiswa mafaira masisitimu.
MuXFS, basa rakaenderera mberi pakukwanisa kushandisa f utilitysck kutarisa uye kugadzirisa matambudziko akaonekwa online, pasina kuburitsa iyo faira system, uchiri mukati Ext4 ikozvino inoshandisa dioread_nolock kufona kwemabhuru madiki kupfuura peji imwe yendangariro, iyo inovandudza kushanda nekubvisa makiyi asina kufanira.
Nezve ndangariro uye sisitimu masevhisi, chimwe chezvinhu zvinonyanya kukosha zveiyi vhezheni itsva ndeye Zswap subsystem kuvandudzwa, sezvo iwe unokwanisa ikozvino kumanikidza kurodha kwemapeji asingawanzo kushandiswa endangariro, nekudaro kusunungura RAM kana zvichidikanwa. Pamusoro pezvo, imwe nzira itsva yakaunzwa inodzima kunyora kumashure kuchikamu chekuchinjana kana kunyora kukatadza, kudzivirira kurodha kwemapeji atove mudziva reZswap.
Imwezve yakakosha yekuwedzera ndeye SCHED_DEADLINE sevha, yakagadzirirwa kugadzirisa kusashanda kweCPU nemabasa enguva dzose kana CPU ichidzorwa nemabasa akakosha, iyo DAMON (Data Access MONitor) subsystem yakakwidziridzwa kuti ibvumidze kutarisa kwekuwana data mu RAM uye otomatiki inogadzirisa mashandisirwo ekurangarira zvinoenderana nechaiyo quotas. Kuunzwa kwerutsigiro rwemapeji makuru ekurangarira uye optimization yeBPF chirongwa chekutarisa ndezvimwe zvakakosha kuvandudzwa mukernel 6.8.
Mumunda we virtualization uye chengetedzo, AppArmor yatama kushandisa iyo SHA-256 algorithm yekusimbisa mutemo, kubviswa kwe strlcpy () basa kubva mu kernel inomiririra nhanho kumberi maererano nechengetedzo, sezvo basa iri, kunyangwe rakagadzirirwa kudzivirira buffer mafashama, rakaratidza kuve rakajairwa kune humwe hurema.
Mumunda we virtualization, iyo hypervisor KVM yakaunza rutsigiro kune guest_memfd subsystem, iyo inopa chaiyo yekurangarira manejimendi masimba evaenzi masisitimu, rutsigiro rweLAM modhi yakagoneswa paIntel processors, ichibvumira chikamu che64-bit pointer bits kuti ishandiswe kuchengetedza metadata, mutyairi weiaa akawedzerwa (IAA Compression Accelerator), iyo inoshandisa iyo Intel Analytics Accelerator (IAA) cryptographic accelerators kuti ikurumidze kudzvanya data uye decompression uchishandisa DEFLATE nzira.
SELinux yakaunza "init" SID yekuona maitiro ekutanga anomhanya SELinux mitemo isati yashandiswa, kuvandudza kuchengetedzwa kwemitemo yekutonga pane system.
Iyo network subsystem yakaona kuvandudzwa mukuita basa caching pamwe neTCP yekumhanyisa nekuda kwekugadziriswazve kweiyo iri pasi data zvimiro. Pamusoro pezvo, iyo bpfilter subsystem yakabviswa uye yakaderera-level optimizations yakaitwa kuvandudza mashandiro.
Padivi remidziyo, vatyairi vatsva vawedzerwa Intel, AMD, NVIDIA uye mamwe mhando dzeGPU, pamwe nerutsigiro rwemhando dzakasiyana dzeARM64 SoCs neArM zvishandiso. Nekudaro, zvakakosha kuti uzive kuti rutsigiro rweARM11 ARMv6K SMP processors rwakamiswa.
pakupedzisira kana uri kuda kuziva zvakawanda nezvazvo, unogona kutarisa ruzivo Mune inotevera chinongedzo.
