Tso tawm ntawm NetBSD 9.0 operating system

Muaj loj operating system tso tawm NetBSD 9.0, nyob rau hauv uas qhov txuas ntxiv ntawm cov yam ntxwv tshiab yog siv. Rau kev thauj khoom npaj installation duab 470 MB loj. NetBSD 9.0 tso tawm yog muaj nyob rau hauv tsim rau 57 system architectures thiab 15 tsev neeg CPU sib txawv.

Cais, muaj 8 qhov chaw txhawb nqa feem ntau uas tsim lub hauv paus ntawm NetBSD txoj kev loj hlob zoo: amd64, i386, evbarm, evbmips, evbppc, hpcarm, sparc64 thiab xen. 49 cov chaw nres nkoj cuam tshuam nrog CPUs xws li alpha, hppa, m68010, m68k, sh3, sparc thiab vax raug cais nyob rau hauv qeb thib ob, i.e. tseem muaj kev txhawb nqa, tab sis tau poob lawv qhov cuam tshuam lossis tsis muaj tus lej txaus ntawm cov neeg tsim khoom txaus siab rau lawv txoj kev loj hlob. Ib qhov chaw nres nkoj (acorn26) suav nrog hauv qeb thib peb, uas muaj cov chaw nres nkoj tsis ua haujlwm uas tsim nyog rau kev tshem tawm yog tias tsis muaj cov neeg nyiam txaus siab rau lawv txoj kev loj hlob.

Ntsiab kev txhim kho NetBSD 9.0:

  • Tshiab hypervisor ntxiv NVMM, uas txhawb nqa hardware virtualization mechanisms SVM rau AMD CPUs thiab VMX rau Intel CPUs. Ib qho tshwj xeeb ntawm NVMM yog tias nyob rau qib ntsiav tsuas yog qhov tsawg kawg nkaus yuav tsum tau teeb tsa ntawm kev khi ib puag ncig hardware virtualization mechanisms tau ua, thiab tag nrho cov kho vajtse emulation code raug tshem tawm ntawm cov ntsiav mus rau hauv cov neeg siv qhov chaw. Txhawm rau tswj hwm cov tshuab virtual, cov cuab yeej raws li lub tsev qiv ntawv libnvmm tau npaj, nrog rau cov pob qemu-nvmm rau kev khiav cov qhua siv NVMM. Libnvmm API npog cov haujlwm xws li tsim thiab khiav lub tshuab virtual, faib kev nco rau cov qhua, thiab faib VCPUs. Txawm li cas los xij, libnvmm tsis muaj cov haujlwm emulator, tab sis tsuas yog muab API uas tso cai rau koj los koom ua ke NVMM kev txhawb nqa rau hauv cov emulators uas twb muaj lawm xws li QEMU;
  • Muab kev txhawb nqa rau 64-ntsis AArch64 architecture (ARMv8-A), suav nrog ARM-raws li server systems ServerReady (SBBR + SBSA), thiab big.LITTLE systems (kev sib xyaw ua ke ntawm cov muaj zog, tab sis lub zog siv cov cores, thiab tsis tshua muaj txiaj ntsig, tab sis ntau lub zog txuag cores hauv ib nti). Nws txhawb kev khiav 32-ntsis daim ntawv thov hauv 64-ntsis ib puag ncig los ntawm kev siv COMPAT_NETBSD32. Txog 256 CPUs tuaj yeem siv tau.
