Kwanan nan an gabatar da sabon tsarin aikin QEMU 4.1, wanda shine aikace-aikace don gani (asali mai kwaikwayo) wanda ke ba da damar gudanar da shirin da aka kirkira don dandamali na kayan aiki akan tsarin tare da tsarin gine-gine daban-daban, misali, gudanar da aikace-aikacen ARM a kan PC mai dacewa da x86.
A cikin yanayin ƙwarewa a cikin QEMU, aiwatar da lambar gudu a cikin keɓantaccen yanayi yana kusa da tsarin asalin saboda aiwatar da umarni kai tsaye akan CPU da amfani da Xen hypervisor ko module KVM.
Babban sabon fasali na QEMU 4.1
QEMU 4.1 Ya zo tare da tallafi don ƙirar Hygon Dhyana da Intel SnowRidge CPU akan emulator na gine-ginen x86, da kuma kwaikwayon RDRAND (mai samar da makarraban makircin makirci na kayan masarufi).
A cikin tsarin koyon aikin MIPS, tallafi don umarnin MSA ASE an inganta lokacin amfani da babban ma'aunin baiti da sarrafa harka-da-sifili an daidaita shi da na'urar tunani. Performanceara aikin kwaikwayon umarnin MSA don ƙididdigar lamba da ayyukan ɓoyewa.
PowerPC Architecture Emulator Yana Gabatar da NVIDIA V100 / NVLink2 GPU Mai Ba da Tallafi ta amfani da VFIO. Don waƙoƙin yabo, ana aiwatar da hanzarin kwaɗaitar direba na XIVE wanda aka katse shi kuma an ƙara tallafi ga gadoji masu zafi-toshe PCI. An gabatar da ingantawa a cikin kwaikwayon umarnin vector (Altivec / VSX).
QEMU 4.1 ya karɓi sabon samfurin kayan aiki, ƙara, zuwa RISC-V emulator architecture emulator, da kuma tallafi ga ISA 1.11.0, haka kuma an inganta kiran tsarin 32-bit ABI tare da fadada aikin koyarwa mara inganci da ingantaccen mai gyara ciki.
Taimako don yin koyi da duk umarnin vector a cikin rukuni An kara "Vector Facility" zuwa s390 emulator emulator, kuma an kara wasu abubuwa don tallafawa tsarin gen15 (gami da tallafi ga AP Queue Interruption Facility for vfio-ap). An aiwatar da tallafin BIOS don farawa daga ECKD DASD zuwa tsarin baƙi ta hanyar vfio-ccw.
SPARC emulator na tsarin gine-gine don tsarin sun4m yana warware matsaloli ta amfani da tutar "-vga none" don OpenBIOS.
Har ila yau abin lura shi ne ƙari na md-bayyanannu da mds-babu tutoci don sarrafa kariya daga hare-haren MDS (Samfurin Bayanan Microarchitectural) akan masu sarrafa Intel. Ara ikon tantance ƙididdigar IC ta amfani da tutar "-smp ..., dies =". Ana aiwatar da sarrafa sigar don duk samfuran CPU x86.
Don zabin "-salvage" an kara shi zuwa umurnin canza qemu-img don musaki dakatarwar da ba daidai ba na aikin canza hoto idan akwai kuskuren shigarwa / fitarwa (alal misali, ana iya amfani dashi don dawo da fayilolin qcow2 da suka lalace ta wani bangare) .
Daga sauran canje-canjen da suka yi fice a cikin wannan sabon sigar:
- An canza mai kula da SSH daga amfani da libssh2 zuwa libssh
- Direio na virto-gpu (GPU mai kama da ci gaba a matsayin wani ɓangare na aikin Virgil) ya ƙara tallafi don wucewa ayyukan 2D / 3D don aiwatar da mai amfani da fatalwar waje (misali vhost-user-gpu)
- Taimakawa don haɓaka ARMv8.5-RNG don ƙirƙirar lambobin ƙira-bazuwar an ƙara shi zuwa emulator tsarin gine-ginen ARM. Aiwatar da tallafi don kwaikwayon FPU don kwakwalwan gidan Cortex-M da warware matsaloli tare da kwaikwayon FPU don Cortex-R5F.
- An gabatar da sabon tsarin don daidaita zaɓuɓɓukan taro, an tsara shi cikin salon Kconfig. Ga Exynos4210 SoCs sun ƙara goyan baya ga masu kula DMA PL330.
- Ara tallafi don karantawa kawai seSparse subformat a cikin VMDK mai kula da toshewa.
- A cikin emulator mai sarrafa iyali na Tensilica Xtensa, ana aiwatar da zaɓuɓɓuka don MPU (naúrar kariya ta ƙwaƙwalwar ajiya) da kuma keɓantacciyar hanya ta musamman
- Ara tallafi don direban SiIO GPIO a direba na kwaikwayo na GPIO.
- Supportara tallafi don topology na CPU a cikin bishiyar na'urar.
- Umurnin "qemu-img rebase" yana ba da aiki yayin da har yanzu ba a ƙirƙiri fayil ɗin ajiya don fayil ɗin shigar da bayanai ba.
