Shalay waxaan ka hadlaynay xoreynta nooca cusub ee Bochs 2.16.10 taas oo badal u ah VirtualBox iyo hadda daahfurka mashruuca QEMU 4.2 ayaa lasoo bandhigay taas oo qaar ka mid ah astaamaha cusub iyo gaar ahaan hagaajinta ayaa la soo bandhigay ilaa mashruuca. U diyaar garowga nooca 4.2, in kabadan 2200 isbedel ayaa laga sameeyay 198 horumariye.
Kuwa aan ka warqabin QEMU waa inay ogaadaan in tan waa emulator kuu ogolaanaya inaad wadato barnaamij la soo ururiyey oo loogu talagalay madal qalab oo nidaam leh qaab dhismeed gabi ahaanba ka duwan, tusaale ahaan, ku shaqeynta arjiga ARM-ka PC-ga x86 ee la jaan qaadi kara.
Qaabka wax ku oolka ah ee QEMU, waxqabadka koodhka socda ee jawiga go'doonsan wuxuu kudhow yahay nidaamka asalka ah sababtoo ah fulinta tooska ah ee tilmaamaha CPU iyo isticmaalka Xen hypervisor ama KVM module.
Astaamaha ugu muhiimsan ee cusub ee QEMU 4.2
Qoraalkan cusub ee QEMU 4.2 emulator-ka dhismaha ARM waxay heshay taageero ku dayashada Aspeed AST2600 SoC «Ast2600-evb» iyo sidoo kale kan taageerada tiknoolajiyada Semihosting 2.0 leh kordhin STDOUT_STDERR / EXIT_EXTENDED, taas oo u oggolaaneysa aaladda lagu dayday inuu isticmaalo stdout, stderr, iyo stdin si uu u abuuro feylal dhinaca martida loo yahay.
Intii loogu talagalay KVM waxay ku dartay awooda isticmaalka in ka badan 256 CPU iyo waxay bixiyaan taageero tilmaamaha SVD SIMD, iyo sidoo kale waxqabadka kudayashada oo la hagaajiyay iyadoo la adeegsanayo matoor code TCG.
Waxaa sidoo kale la iftiimiyay in nooc cusub oo ah mishiinka microvm ayaa lagu daray ku dayasho emulator naqshadaha x86, iyadoo la isticmaalayo viryo-mmio halkii laga isticmaali lahaa PCI si loo hagaajiyo waxqabadka. Awoodda karti u yeelashada iyo ka joojinta VMX iyada oo loo marayo «-processor«.
Taageero lagu daray kudayashada AVX512 BFloat16 kordhinta. Taageero ayaa loo fidiyay Denverton cusub (Soom server-ka saldhiggiisu yahay Atom), qaababka Snowridge iyo Dhyana CPU. Taageerada xasilloon ee MacOS Hypervisor Framework («-Accel hvf").
Darawalka qalabka Shabakada Xirmooyinka Shabakada (NBD), waxay siisaa waxqabad hufan oo ku saabsan codsiyada nuqul akhriska ah. The NBD koodhka adeegaha ayaa loo habeeyay si loo koobiyeysto sawirro aan badnayn (oo aan lahayn) Waa la xaqiiqsaday Horumarinta guud ee macmiilka NBD iyo hirgelinta serverka.
Wixii ah Emulator dhismeedka PowerPC leeyahay kartida ku dayashada tilmaamaha AWOODA9 mffsce, mffscrn iyo mffscrni. Mashiinnada lagu daydo, "powernv" ayaa lagu daray Taageerada qalabka nidaamka Homer iyo OCC SRAM.
In virio-mmio ayaa ku darsaday dabiici ahaan-socon kara heerka 2 iyo virio qeexan gaar ah 1,1 Nidaamka Safka ah ee loo yaqaan 'Virtual Packed Queue (virqueue') oo loogu talagalay is-weydaarsiga xogta aaladda I / O ee teknoolojiga ah ee qaab dufcaddeed
Isbeddelada kale oo ka soocan noocyadan cusub ee QEMU 4.2:
- Aaladda koronto-dhaliyaha caadiga ah ee TCG (Tiny Code Generator) waxay taageertaa plugins si loola socdo tilmaamaha processor-yada iyo cinwaanada ku jira xusuusta.
- Waxqabadka 'encryption disk' sare ee LUKS iyadoo la adeegsanayo algorithm-ka AES-XTS.
- Vfio-pci waxay ku dareysaa taakuleynta hantida guuldarada_labo_id si loo fududeeyo socdaalka aaladaha VFIO.
- Xulashada "-initrd" ayaa lagu daray emulator-ka dhismaha RISC-V iyo awooda lagu arko heerka buuxa ee naqshadaha naqshadeeyaha.
- Emulator qaab dhismeedka s390 wuxuu taageeraa IEP (Ilaalinta fulinta fulinta).
- In Emulator 68k naqshadaha, awoodda bilowga ah ee ku dayashada Macintosh Quadro 800 iyo nidaamyada NeXTcube caadiga ah ayaa lagu daray.
- Aaladda emulator-ka ee xtensa, nooc cusub oo "mishiinno" lagu daydo ah ayaa lagu daray iyo ABI call0 taageerada kudayashada goobta-isticmaalaha ayaa la hirgaliyay.
Sidee loo rakibaa QEMU 4.2 Ubuntu iyo waxyaabaha la mid ah?
Rakibaadda noocaan cusub ee QEMU hadda lagama heli karo marinnada rasmiga ah ee Ubuntu, laakiin waa inaan dhowr maalmood sugnaa in binaries laga heli karo keydadka.
Isla marka la helo, waa ku filan tahay fur terminal (waxaad ku sameyn kartaa adigoo adeegsanaya toobiye Ctrl + Alt + T) waxaanan qoreynaa waxyaabaha soo socda:
sudo apt-get install qemu-kvm qemu virt-manager virt-viewer libvirt-bin
Ama sidoo kale waxay sameyn karaan rakibaadda waxayna sugi karaan cusbooneysiinta cusub si loo ogeysiiyo oo kaliya loo cusbooneysiiyo xirmooyinka.
