QEMU 5.1 nyob ntawm no thiab tuaj txog 2500 kev hloov pauv thiab cov no yog qhov tseem ceeb tshaj plaws

QEMU

Lub community launch txog cov tshiab version ntawm qhov project QEEM 5.1, nyob rau hauv uas txhawb rau ntau txheej txheem tau ntxiv, nrog rau kev txhim kho kev txhawb nqa NVMe, kab laum txhim kho thiab txhim kho rau yam uas twb tau tsim.

Rau cov neeg uas tsis paub txog QEMU, lawv yuav tsum paub tias qhov no tso cai rau koj los khiav ib qho kev tso ua ke rau lub platform kho vajtse hauv lub kaw lus nrog a txawv kiag li architecturePiv txwv li, khiav daim ntawv thov ARM ntawm lub x86 tshaj PC.

Nyob rau hauv hom virtualization hauv QEMU, kev ua tiav ntawm kev khiav dej num hauv sandbox yog ze rau cov kab ke haiv neeg vim kev coj ncaj qha ntawm cov lus qhia ntawm CPU thiab siv Xen hypervisor lossis KVM module.

Qhov hauj lwm no tau tsim los ntawm Fabrice Bellard kom tso cai x86 muab tso ua ke Linux binaries khiav ntawm cov x-tsis muaj cov kos duab.

Xyoo dhau los ntawm kev txhim kho, tag nrho cov kev txhawb nqa kev txhawb nqa tau ntxiv rau 14 lub tuam tsev kho vajtse, cov xov tooj ntawm cov khoom siv kho vajtse tau tshaj li 400 tus.

Lub ntsiab tshiab tshiab ntawm QEMU 5.1

Hauv kev npaj ntawm daim ntawv tshiab no 5.1, ntau tshaj 2500 qhov pauv hloov, ntawm uas 235 tus neeg tsim khoom koom nrog.

Ntawm cov kev hloov pauv loj uas sawv tawm hauv qhov tshiab no, peb tuaj yeem pom tau tias nws tau ntxiv txhawb rau CPU emulation raws li AVR architecture, zoo li kuj ntxiv kev txhawb nqa rau Arduino boards Duemilanove (ATmega168), Arduino Mega 2560 (ATmega2560), Arduino Mega (ATmega1280), thiab Arduino UNO (ATmega328P).

Nws tseem hais tias txuas kev txuas ntxiv thiab nvdimm rau ACPI qhua tshuab rau ARM emulator, Ntxiv rau, qhov kev txhawb nqa siv kuj tau ntxiv rau ARMv8.2 TTS2UXN thiab ARMv8.5 MemTag txuas ntxiv

Ntxiv rau kev them nyiaj yug rau Loongson 3A CPU (R1 thiab R4) rau MIPS architecture emulator. Txhim kho kev ua tau zoo ntawm FPU thiab MSA emulation kev qhia, nrog rau kev txhawb rau SiFive E34 thiab Ibex CPUs rau RISC-V architecture emulator. Ntxiv kev txhawb nqa rau HiFive1 revB thiab OpenTitan cov laug cam. Ntau tshaj ib lub CPU tau txais kev txhawb nqa rau Spike tshuab.

Rau maub los NVMe ntxiv kev txhawb nqa rau kev nco tsis tu ncua cheeb tsam tshaj tawm hauv NVMe 1.4 cov ntsiab lus tshwj xeeb.

Thiab ntxiv rau qhov tshiab 'bitmap' cov lus txib tau ntxiv rau qemu-img chaw tso hluav taws xob los tswj tuav cov teeb meem me hauv qcow2 cov ntaub ntawv.

Qemu-img kuj tseem siv LUKS kev tswj xyuas qhov tseem ceeb (keyslot) thiab muaj cov peev xwm ntxiv rau cov "daim ntawv qhia" (–start-offset, –max-ntev) thiab "hloov pauv" (–bitmaps) cov lus txib, ntxiv rau cov kev ntsuas «ntsuas» los tsim cov ntaub ntawv ntawm qhov loj me ntawm tas mus li bitmaps hauv qcow2 cov ntaub ntawv.

Ntawm lwm qhov kev hloov pauv uas sawv tawm ntawm no tshiab version:

  • Lub PowerPC architecture emulator tam sim no muaj kev txhawb nqa rau kev ua yuam kev rov qab rau cov qhua tuaj yeem siv FWNMI.
  • Rau s390 architecture, KVM kev txhawb nqa tau ntxiv rau kev ruaj ntseg virtualization (kev tswj hwm kev nyab xeeb).
  • Tus x86 architecture emulator txo qhov nyiaj siv ua haujlwm ntawm virtualizing tsis paub txog cov qhua Windows los ntawm kev muab Windows ACPI Emulated Device Table (ACPI WAET). Txhim kho kev txhawb nqa rau HVF acceleration rau macOS.
  • Lub block ntaus ntawv tsav tsheb ntxiv kev txhawb nqa rau cov khoom siv virtual cia nrog 2 MB lub cev thiab cov laj thawj.
  • Ntxiv lub peev xwm los hloov cov passwords thiab cov yuam sij rau QEMU rau encryption ntawm Linux lub pob keyring siv qhov tshiab "zais keyring" yam khoom.
  • Zstd compression algorithm tam sim no txhawb nqa qcow2 hom.
  • Sonorapass-bmc board yog txaus siab.
  • Kev tsim nyog rau cov qhua nrog lub qub TCG (Cov Tsim Hluav Taws Xob Me Me) muaj peev xwm siv vhost cov neeg siv txheej txheem, suav nrog kev tsim txiaj. Ntxiv rau VHOST_USER_PROTOCOL_F_CONFIGURE_MEM_SLOTS txuas ntxiv mus rau vhost-tus neeg siv, tso cai rau ntau tshaj 8 RAM qhov tau rau npe.
  • Ntxiv ib qho interface los txhaj tshuaj POWER style NMI
  • Cov lus qhia Scv thiab rfscv yog tam sim no TCG li txoj cai
  • Tam sim no koj tuaj yeem xaiv POWER10 nrog tshuab hom «chaw sau»
