Red Hat yakavhurwa Mazuva mashoma apfuura kuburitswa kweshanduro nyowani yeRed Hat Enterprise Linux 8.4. Bazi re8.x, iro rinotsigirwa kusvika kanosvika muna 2029, riri kuchinja zvichiteerana neyakajeka fungidziro yebudiriro, iyo inosanganisira kuumbwa kwekuburitswa kwemwedzi mitanhatu yega yega panguva yakatarwa.
RHEL's nyowani yechigadzirwa yekuvandudza kutenderera inotenderera akawanda masenduru, kusanganisira Fedora sechitubu chemano nyowani, CentOS Stream yekuwana mapakeji einotevera kuburitswa kweRHEL (RHEL mobile variant), minimalist universal base image (UBI, Universal Base Image) kumhanya zvinoshandiswa mumidziyo yakasarudzika uye RHEL mushambadzi kunyorera kushandisa RHEL yemahara panguva yekuvandudza.
Chii Chitsva muRed Hat Enterprise Linux 8.4
Mune iyi vhezheni itsva yakawedzera rutsigiro rwekuyedza rweprotrotocol yekushandura tekinoroji (MPLS) kufambisa mapaketi uchishandisa multiprotocol label switching. Uchishandisa MPLS, semuenzaniso, inokutendera iwe kutsanangura mafirita kuburikidza neiyo tc utility kudzora mapakeji anouya kubva kune akasarudzika madoko kana akabatana nerumwe rudzi rwe traffic.
Tinogona zvakare kuona kuti iyo tsigiro ye proactive compacting michina yemapeji ekurangarira kumashure (proactive compaction), iyo inobvumidza kuwedzera huwandu hwemapeji makuru ekurangarira (makuru mapeji, mapeji makuru kupfuura 4KB) anowanikwa kune kernel. Otomatiki kumashure kurongedza (defragmentation) pamutengo weushoma pamusoro inobvumidza 70-80 nguva yakaderera latency kana uchigovera makuru ndangariro mapeji achienzaniswa neyaimbove yakashandiswa pane-inoda kurongedza mashandiro, ayo anotangwa zvakananga pakugovera peji hombe. Nekutadza, proactive compaction mode yakaremara izvozvi.
Iyo nyowani slab memory controller inoshandiswa, izvo zvinozivikanwa nekuchinjiswa kweslab accounting kubva padanho repamusoro rendangariro kuenda padanho rechinhu chekernel, zvichiita kuti zvikwanisike kugovana mapeji echi slab mumapoka akasiyana, pane kugovera akapatsanurwa masirabhu eecheka rimwe nerimwe. Maitiro akarongwa anotendera kuwedzera kugona kwekushandisa kwesirabhu, kudzikisira saizi yendangariro yakashandiswa neslab ne30-45%, zvakanyanya kudzora iko kurangarira kushandiswa neiyo kernel uye kuderedza kupatsanurwa kwendangariro.
Mukuwedzera yakatsiga rutsigiro yakapihwa iyo XDP subsystem (eXpress Data Path), iyo inokutendera iwe kushandisa mapaketi enetiweki mudariro zvisati zvagadziriswa neLinux kernel network stack. Semuenzaniso, uine XDP, unogona kumhanyisa zvirongwa zveBPF padanho rekutyaira network nekuwana kwakananga kune iyo DMA packet buffer uye pamberi penzvimbo stack haina kugovera skbuff.
Wakawedzera kugona kudzosa isingashandiswe ndangariro nemamishini chaiwo kune hypervisor. Iyo virtio_balloon inobata inofanirwa kushandiswa kudzosa mapeji endangariro kudivi reVM.
Realtime zvinhu (kernel-rt) zviri kuenderana nekernel chigadziko set v5.10-rt7 (yaimbove 5.6.14-rt7). Inosanganisira yekuchengetedza yekumashure maitiro ayo anotarisa tambo kana uchivhura zvine mutsindo zvinoshandiswa. Kana tambo dzakarara dzikaonekwa, shanduko yenguva pfupi inoitwa kune iyo SCHED_DEADLINE kuronga mutemo uye yakawedzera CPU nguva inopihwa kune iyo tambo.
Uyewo akawedzera kernel module nerutsigiro rweiyo EDAC michina (Kanganiso Kuonekwa uye Kururamisa), yakapihwa pachizvarwa chechisere nechipfumbamwe chiziviso cheIntel Core, kuona nekugadzirisa zvikanganiso mundangariro yeECC nebhazi rePCI.
Iyo fapolicyd fomati, iyo inobvumidza iwe kuona kuti ndeapi mapurogiramu anogona kuvhurwa nemumwe mushandisi uye asingakwanise, akawedzerwa kutsigira Integrity Measurement Architecture (Kuvimbika Kuyera Architecture) uye yakaitwa kunyora RPM mapakeji ekuvandudza.
