Oracle yakaburitsa iyo Unbreakable Enterprise Kernel R5U2

Oracle Company yakaburitswa chechipiri chimiro chekuvandudza kwe kernel Isingaputsike Enterprise Kernel R5, yakamisikidzwa kuti ishandiswe mukugoverwa kweOracle Linux seimwe nzira kune yakajairwa package ine kernel kubva kuRed Hat Enterprise Linux. Iyo kernel inowanikwa kune x86_64 uye ARM64 (aarch64) zvivakwa. Kernel masosi, kusanganisira kuparara kuita zvigamba zvega, rakabudiswa mune yeruzhinji Oracle Git repository.

Isingaputsike Enterprise Kernel 5 yakavakirwa pane kernel Linux 4.14 (UEK R4 yaive yakavakirwa pa4.1 kernel), iyo inogadziridzwa nemaitiro matsva, optimizations uye zvigadziriso, uye zvakare inoedzwa kuti ienderane neakawanda maapplication ari kushanda paRHEL, uye yakanyatso gadziridzwa kushanda neOracle industrial software uye hardware. Kuiswa uye src mapakeji ane UEK R5U1 kernel yakagadzirirwa yeOracle Linux 7.5 uye 7.6 (hapana zvipingamupinyi pakushandisa kernel iyi mushanduro dzakafanana dzeRHEL, CentOS uye Scientific Linux).

Key kuvandudzika:

• Mapeche akatamiswa pamwe nekuitwa kwePSI (Pressure Stall Information) subsystem, iyo inokutendera kuti uongorore ruzivo nezve nguva yekumirira yekuwana akasiyana zviwanikwa (CPU, ndangariro, I / O) kune mamwe mabasa kana seti yemaitiro muboka. . Uchishandisa PSI, vashandisi venzvimbo yevashandisi vanogona kunyatso kuenzanisa mwero wehurongwa hwekutakura uye kuderera kwemaitiro zvichienzaniswa neAvhareji Yemutoro;
• Kune cgroup2, iyo cpuset resource controller inogoneswa, iyo inopa nzira yekudzikamisa kuiswa kwemabasa paNUMA memory node uye CPUs, zvichibvumira kushandiswa kwezviwanikwa chete zvinotsanangurwa kuboka rebasa kuburikidza necpuset pseudo-FS interface;
• Iyo ktask chimiro chakaitwa kuenzanisa mabasa mukernel anoshandisa zvakakosha CPU zviwanikwa. Semuyenzaniso, kushandisa ktask, parallelization of operations to clear ranges of memory mapeji kana kugadzirisa rondedzero yeinode inogona kurongeka;
• Mune DTrace akawedzera tsigiro yekutorwa kwepaketi kuburikidza ne libpcap uchishandisa chiitiko chitsva "pcap(skb,proto)" Semuyenzaniso "dtrace -n 'ip:::send {pcap((void *)arg0, PCAP_IP); }'";
• Kubva kutsva kernel kuburitswa kutakurwa zvigadziriso mukushandiswa kweiyo btrfs, CIFS, ext4, OCFS2 uye XFS mafaira masisitimu;
• Kubva kernel 4.19 kutakurwa shanduko dzine chekuita nerutsigiro rweKVM, Xen uye Hyper-V hypervisors;
• Updated madhiraivha emudziyo uye akawedzera rutsigiro rweNVMe madhiraivha (shanduko kubva kukernels 4.18 kusvika 4.21 dzakatamiswa);
• Kugadziridza kwakaiswa kuti ikwidze kuita pamapuratifomu eARM.
