I-Linux 5.18 sele ikhutshwe kwaye iza neenguqu ezininzi kunye nophuculo

Kwiintsuku ezithile ezidlulileyo ULinus Torvalds ubhengeze ukufumaneka ngokubanzi koguqulelo oluzinzileyo lweLinux 5.18, inguqulo efika ngokuchanekileyo kwiinyanga ezimbini emva koluhlu lwe-Linux 5.17 kernel kwaye ifumene izigaba ezisibhozo ze-RC (Ukukhutshwa koMviwa) kuwo wonke umjikelezo wayo wophuhliso, oye wanceda abaphuhlisi be-kernel ukulungisa iziphene kunye nokuphucula iimpawu ezikhoyo.

Phakathi kwezona nguqu zibalulekileyo zale nguqulo entsha ye-Linux Kernel 5.18 ibandakanya utshintsho kumgangatho wokuhlanganiswa kwe-C11, inkxaso "yeziganeko zabasebenzisi" kwinkqubo yokulandelela, inkxaso "ye-host system management port" umsebenzi » ukusuka kwi-AMD, inkxaso ye-64. Ukuhlolwa kwengqibelelo kancinci kwizixhobo zeNVMe, kunye nokunye.

Iimpawu ezintsha eziphambili zeLinux 5.18

Izongezo ezininzi ezivela kwi-Intel zenziwe kule nguqulo entsha ye-Linux Kernel 5.18, kuquka umqhubi omtsha "I-Hardware Feedback Interface" (I-HFI) yeeprosesa ezixubileyo ezifana ne-Alder Lake, "i-Software Defined Silicon" (SDSi) iye yadityaniswa ukuze isebenze iimpawu zesilicon ezinelayisenisi ze-Intel CPUs ezizayo, "Intel Indirect Branch Tracking" (IBT) njengenxalenye ye "Control-Flow Enforcement Technology". ”, “ENQCMD” iphinde yavulwa kwiSapphire Rapids nokunye. I-Intel PECI, i-Platform Environmental Control Interface, iye yadityaniswa kwi-interface phakathi kwe-CPU kunye ne-BMC kumaqonga e-Intel server.

Los amalungiselelo e-Intel IPI virtualization nayo yafika kwi-Linux 5.18, ngelixa ukusebenza kwangempela kufuneka kube khona kumjikelo we-v5.19. Ngokuphathelele i-Intel entsha kwindawo yemizobo, iLinux 5.18 ibonelela ngenkxaso ye-DG2 G12 sub-platform, inkxaso Intel Alder Lake N yemizobo kunye ezahlukeneyo DG2/Alchemist yenza amasuntswana.

Kukwakho nomsebenzi kwi-AMD EDAC yeZen 4 CPUs, uphuculo olubekwe kwindlwane ukusuka kwi-AMD kunye nomnye umsebenzi kwiZen 4. I-KVM eneLinux 5.18 ikwahambelana noomatshini benyani be-AMD ukuya kuthi ga kwi-511 vCPUs, ukusuka kwi-255 vCPUs namhlanje, kwaye igqithise isizukulwana samva nje se-EPYC. iiseva ezibonelela ngenani eliphezulu leecores ngeBergamo. Ngokuphathelele imizobo ye-AMD, i-Linux 5.18 yenza ukuba i-AMDGPU ye-FreeSync "imowudi yevidiyo" ngokuzenzekela, ebifihliwe emva kokhetho lwemodyuli kwiinkozo zangaphambili.

Iibhloko zokuqala ze-IP zikwanikwe amandla kwii-GPU kunye nee-APU isizukulwana esilandelayo, kodwa ngaphezulu kucwangciswe kwi-kernel 5.19. Ngokuphathelele kwi-hardware, i "I-Raspberry Pi Zero 2W" inenkxaso epheleleyo ye-Linux kernel kule nguqulo.

Ukongezelela, inkqubo yefayile yeReiserFS iye yachithwa kwaye kulindeleke ukuba isuswe ngo-2025. Ukuchithwa kwe-ReiserFS kuya kunciphisa umzamo ofunekayo ukugcina utshintsho lwenkqubo yeefayile eziqhelekileyo ukuxhasa i-mount entsha, iomap, kunye ne-APIs yevolumu.

Kuyacaciswa ukuba ikhowudi yokubala izibalo yenziwe ngokutsha kubaqhubi beDivaysi-mapper, eye yaphucula kakhulu ukuchaneka kobalo kubaqhubi abafana ne-dm-crypt. Kwizixhobo ze-NVMe, inkxaso ye-64-bit checksums yokutshekisha ingqibelelo iphunyeziwe.

Ngakolunye uhlangothi, kugxininiswe ukuba ukuhlanganiswa kweeseti zeepetshi kuqalile, enokunciphisa kakhulu ixesha lokwakha kwakhona i-kernel ngokuhlengahlengisa ulawulo lweefayile zentloko kunye nokunciphisa inani lokuxhomekeka komnqamlezo. I-Kernel 5.18 ibandakanya iipetshi eziphucula ubume beefayili zentloko yomcwangcisi (i-kernel/sched).

Ikhowudi yekernel inokusebenzisa umgangatho weC11, yapapashwa ngo-2011. Ngaphambili, ikhowudi eyongeziweyo kwikernel kwafuneka ithobele i-ANSI C (C89) ingcaciso, eyathi yasekwa ngo-1989. Utshintshe i-'–std=gnu89' ibe '–std=gnu11 -Wno-shift- negative. -ixabiso' kwi-5.18 kernel build scripts. Ukukwazi ukusebenzisa umgangatho we-C17 kwakucatshangelwa, kodwa kulo mzekelo kuya kufuneka ukuba kwandiswe inguqu encinci exhaswayo ye-GCC, ngelixa ukufakwa kwenkxaso ye-C11 kuhambelana neemfuno zangoku zenguqu ye-GCC (5.1).

Kwakhona Izixhobo ezongeziweyo zokulandelela izicelo kwindawo yomsebenzisi zibonakalisiwe. Inguqulelo entsha yekernel yongeza amandla eenkqubo zomsebenzisi ukwenza imicimbi yabasebenzisi kwaye ibhale idatha kwi-trace buffer, enokujongwa ngezinto eziqhelekileyo zomkhondo we-kernel ezifana ne-ftrace kunye ne-perf.

Okokugqibela, ukuba unomdla wokwazi ngakumbi ngayo, ungajongana neenkcukacha kwi ukulandela ikhonkco.
