Thaum Lub Tsib Hlis 19, OpenBSD 6.7, ib lub operating system zoo li UNIX pub dawb, tau tso tawm. Lub system no yog tus cwj pwm los ntawm nws qhov kev tsom mus rau qhov zoo ntawm cov code thiab kev ruaj ntseg. Lub project tau tsim los ntawm Theo de Raadt hauv xyoo 1995 tom qab muaj kev tsis sib haum xeeb nrog cov neeg tsim khoom NetBSD. Cov kev hloov pauv tseem ceeb tshaj plaws hauv qhov kev tso tawm tau teev hauv qab no.
- Txog li 15 qhov kev faib tawm ntawm ib lub cuab yeej siv tam sim no tau txais kev txhawb nqa. Xav paub ntxiv
- Kev siv mploc uas tsis siv tshuab rau lub platform powerpc.
- Kev kho kom zoo ntawm kev ntxuav nplooj ntawv nco.
- Muaj ntau yam kev txhim kho thiab kho kab laum hauv dhclient, DHCP client.
- Qhov loj tshaj plaws ntawm block rau NVMe kev ua haujlwm yog 128K.
- Kev txhim kho rau apmd daemon, uas yog lub luag haujlwm rau hibernation/pw tsaug zog. Daemon tau txais cov ntaub ntawv hais txog kev hloov pauv fais fab los ntawm lub roj teeb tsav tsheb. Cov lus ntawm tus tsav tsheb raug tsis quav ntsej rau 60 vib nas this tom qab lub khoos phis tawj rov pib dua, uas tso cai rau tus neeg siv rov ua haujlwm ua ntej lub tshuab rov qab mus pw tsaug zog.
- Ntxiv lub peev xwm los tsim cov ntaub ntawv tsis muaj npe hauv tmpfs. Qhov no yuav txwv tsis pub daim ntawv thov nkag mus rau hauv cov ntaub ntawv system.
- Ntxiv hom uas tib neeg nyeem tau rau systat (-h xaiv).
- Tus cwj pwm dhclient qub tau rov qab los lawm. Lub kaw lus yuav tsis quav ntsej txog kev sib txuas uas tsis muab lub ntsej muag subnet.
Kev txhim kho hauv ffs2 cov ntaub ntawv system siv 64-bit timestamps thiab block addresses:
- Tam sim no ffs2 siv los ntawm lub neej ntawd rau txhua lub platform tshwj tsis yog landisk, luna88k thiab sgi.
- Kev txhawb nqa rau kev faib khau raj thiab ramdisk rau lub platform sgi.
- Kho qhov chaw thauj khoom rau sparc64 thiab Mac PPC.
- Rub tawm muaj rau alpha thiab amd64 platforms.
- Muaj peev xwm khau raj rau arm_v7 thiab arm64 platforms siv efiboot.
- Kev xaiv rub tawm rau lub platform loongson.
Kev txhim kho SMP:
- Cov kev hu xov tooj ntawm __thrsleep, __thrwakeup, kaw, kaw los ntawm, dup, dup2, dup3, flock, fcntl, kqueue, yeeb nkab, yeeb nkab2, thiab nanosleep tam sim no khiav yam tsis muaj KERNEL_LOCK.
- Qhov kev siv SMP rau AMD processors tau raug kho dua tshiab. Lub kaw lus yuav tsis txheeb xyuas cov cores ua threads tsis raug lawm.
Cov tsav tsheb:
- Kev txhim kho hauv tus tsav tsheb em uas muaj lub luag haujlwm txhawb nqa Intel PRO/1000 10/100/Gigabit Ethernet network cards.
- Siv kev daws teeb meem microsecond siv microcputime rau Cherry Trail processors los kho X startup hangs.
- Kev txhawb nqa rau qhov chaw nyob nco hauv PCI cov khoom siv rau LPSS (Low Power Subsystem).
- Kev txhawb nqa rau x553 maub los hauv ix tsav tsheb, uas yog lub luag haujlwm rau cov ntawv qhia ceev ceev Intel network siv PCI Express interface.
- Kho cov kab tom qab pw tsaug zog / hibernation rau amdgpu thiab radeondrm.
- Kho rau HP EliteBook khov thaum khau raj hauv UEFI hom.
- Cov ntsiab lus ntxiv tuaj yeem pom nyob rau hauv thawj qhov kev tshaj tawm ntawm lub vev xaib official ntawm qhov project.
Thiab kuj:
- Cov tsav tsheb hauv qab no tau raug tshem tawm lawm:
- rtfps, lub luag haujlwm rau qhov chaw nres nkoj serial ntawm IBM RT PC boards;
- dpt rau DPT EATA SCSI RAID;
- gpr rau cov nyeem daim npav ntse ntawm PCMCIA interface GemPlus GPR400;
- mesh, rau SCSI expansion phaib hauv Power Macintosh;
- Lub suab subsystem tau zoo dua.
- Ntxiv kev txhawb nqa rau RaspberryPi 3/4 ntawm arm64 architecture thiab RaspberryPi 2/3 ntawm arm_v7 architecture.
Ib txwm muaj, daim ntawv tshaj tawm :)
