Zimbalwa izinsuku ezedlule ukukhishwa kwenguqulo entsha ye-QEMU 7.0 kumenyezelwe, okuvumela ukuthi usebenzise uhlelo olwakhelwe inkundla yehadiwe eyodwa ohlelweni olunezakhiwo ezihluke ngokuphelele, isibonelo, ukusebenzisa uhlelo lwe-ARM ku-PC ehambisana ne-x86. Kumodi ye-virtualization ku-QEMU, ukusebenza kokukhishwa kwekhodi endaweni engayodwa kufana nalokho kwesistimu yehadiwe ngenxa yokwenziwa ngokuqondile kwemiyalelo ku-CPU kanye nokusetshenziswa kwe-Xen hypervisor noma imojula ye-KVM.
Phakathi neminyaka yokuthuthuka, ukusekelwa okugcwele kokulingisa kwezakhiwo zehadiwe eziyi-14 zengeziwe, inani lemishini yehadiwe elingisiwe ladlula ama-400. Ukulungiselela inguqulo 7.0, izinguquko ezingaphezu kuka-2500 zenziwe kusukela konjiniyela abangama-225.
Izindaba eziyinhloko ze-QEMU 7.0
Kule nguqulo entsha ye-QEMU 7.0 eyethulwe, i Ukusekelwa kwesethi yemiyalo ye-Intel AMX (Izandiso ze-Matrix Ezithuthukisiwe) yenziwe ku ama-server processors I-Intel Xeon i-Scalable futhi yengezwe kusifanisi sezakhiwo ze-x86. I-AMX inikezela ngamarejista amasha e-TMM “TILE” angokwezifiso nemiyalo yokukhohlisa idatha kulawa marejista, njenge-TMUL (I-Tile matrix MULtiply) yokuphindaphinda kwe-matrix.
Olunye ushintsho olugqamile yilolo Ukuvumelana nezimo kokulondoloza izithombe ezisebenzayo kuthuthukisiwe isistimu yamanje (isithombe esifinyeziwe siyakhiwa, ngemva kwalokho kusetshenziswa isihlungi sekhophi-ngaphambi kokubhala (CBW) ukuze kubuyekezwe isimo sesifinyezo, kukopishwe idatha ezindaweni uhlelo lwesivakashi elibhalela kuzo). Ikhono lokufinyelela isifinyezo esinesipele alinikezwanga ngokuqondile, kodwa kunalokho ngomshayeli wedivayisi ye-snapshot block.
I-ARM emulator yemishini ye-'virt' yengeze ukwesekwa kwe-virtio-mem-pci, Ukutholwa kwe-topology ye-CPU yesivakashi nokunika amandla i-PAuth lapho kusetshenziswa i-hypervisor ye-KVM ene-accelerator ye-hvf, kanye nokwesekwa okwengeziwe kwe-PMC Flash OSPI nokulingisa umshayeli we-SLCR kusifanisi sebhodi 'xlnx-versal-virt'.
I-emulator yokwakha I-RISC-V yengeza ukwesekwa kwe-KVM hypervisor futhi isebenzisa izandiso zevekhtha ye-Vector 1.0, kanye nosekelo lokulayisha ama-binaries we-OpenSBI (RISC-V Supervisor Binary Interface) wemishini 'yespike' elingisiwe yengeziwe. Emishinini elingisiwe ye-'virt', ikhono lokusebenzisa ama-processor cores afika kwangu-32 nokusekelwa kwe-AIA kuyasetshenziswa.
Of ezinye izinguquko okugqamile:
- I-emulator ye-architecture ye-HPPA inikeza ama-vCPU angafika kwangu-16 kanye nesilawuli sezithombe esithuthukisiwe sezindawo zabasebenzisi be-HP-UX VDE/CDE.
- Kwengezwe amandla okushintsha i-oda lokuqalisa lamadivayisi e-SCSI.
- Usekelo olungeziwe lokusebenzisa ama-CPU cores angafika kwangu-4, ukulayisha isithombe se-initrd sangaphandle, futhi sikhiqize ngokuzenzakalela isihlahla sedivayisi somongo ovulelekayo kusifanisi sezakhiwo se-OpenRISC samabhodi 'esim'.
- Isilingisi sezakhiwo se-PowerPC semishini 'ye-pseries' esilingisiwe sisebenzise amandla okusebenzisa amasistimu wezihambeli ngaphansi kokulawulwa kwe-hypervisor efakwe esidlekeni ye-KVM. Kungezwe usekelo lwedivayisi ye-spapr-nvdimm.
- Usekelo olungeziwe lwesibambi esiphazamisayo se-XIVE2 nezibambi ze-PHB5 zemishini elingisiwe ye-'powernv', usekelo oluthuthukisiwe lwe-XIVE ne-PHB 3/4.
- Kungezwe usekelo lwezandiso ze-z15 (Isikhungo-Isifundiso-Esengeziwe 3) kusifanisi sezakhiwo se-s390x.
- I-Classic TCG (i-Tiny Code Generator) isuse usekelo lwabasingathi abanama-ARMv4 kanye nama-ARMv5 CPUs angakusekeli ukufinyelela kwememori okungahleliwe futhi angenayo i-RAM eyanele yokusebenzisa i-QEMU.
- Ukusekelwa kwamalebula okuvikela kumojula ye-virtiofs, esetshenziselwa ukudlulisela ingxenye yesistimu yefayela ukusuka endaweni yokusingatha kuya kusistimu yesivakashi, kuthuthukisiwe.
- Ukuba sengozini okugxilile CVE-2022-0358, okukuvumela ukuthi ukhuphule amalungelo akho kusistimu ngokudala amafayela asebenzisekayo kuzinhlu ezidluliswa ngama-virtiofs, aphethwe elinye iqembu futhi afakwe ifulegi le-SGID.
Okokugcina uma unentshisekelo yokwazi kabanzi ngakho ngezinguquko nezinto ezintsha ezethulwe kule nguqulo entsha ye-QEMU 7.0 ungabheka imininingwane nokunye okwengeziwe isixhumanisi esilandelayo
