I-Linux 6.18-rc4 Ngoku iyafumaneka njengolwakhiwo olutsha lovavanyo lweveki. Emva kweeveki ezininzi ezolileyo, umjikelo uhlala uzinzile kwaye usendleleni yokuhanjiswa ngasekupheleni kukaNovemba okanye ekuqaleni kukaDisemba. Umviwa wesine ukuba akhululwe Ifika kakuhle kwaye igxininise kwiinkcukacha zokupholisha, njengoko kucacisiwe kwi Yintoni entsha kwiLinux 6.18-rc3.
ULinus Torvalds uye wazisa iiyure ezimbalwa phambi kohambo ngalunye, kodwa ngaphandle kotshintsho olusisiseko kwisicwangciso: eyona iphambili ukulungiswa komqhubi (GPU, inethiwekhi kunye nesandi) kunye nohlengahlengiso oluncinci kuthungelwano, iinkqubo zefayile (i-SMB, i-XFS kunye ne-nfsd), umcwangcisi owandisiweyo (sched_ext) kunye ne-s390 kunye ne-x86 ye-architectures, kunye novavanyo olutsha oluzenzekelayo lwe-VFIO.
Iimpawu ezintsha kunye notshintsho oluphambili kwiLinux 6.18-rc4
Kwi-x86, olona tshintsho luphawulekayo kukwandiswa kweziphawuli zemodeli ezayo ye-AMD Zen 6 (usapho lwe-1Ah). I-kernel ngoku iqaphela iimodeli ezongezelelweyo ezili-16 ngokwandisa uluhlu lwangaphambili, ngaloo ndlela lula inkqubo yokulungiselela. iimveliso ezisekelwe kwiZen 6 eya kufika emarikeni, ngendlela efanayo naleyo ichazwe kuyo Linux 6.18-rc2.
Kwakhona kumphambili we-AMD, i-kernel ivala ukusetyenziswa kwe-RDSEED kwiinkqubo ezithile ze-Zen 5 ezine-microcode eyandulela i-firmware patch, ithomalalisa umba owaziwayo wokungakhethi. I-AMD sele isasaza ukuhlaziywa kwe-EPYC 9005, kwaye abanye baya kufika kungekudala; okwangoku, i-kernel ibandakanya oku ukhuseleko kwi-RDSEEDUkongeza, ungqamaniso lwemeko ye-XFD ye-FPU xa unikezela ngemiqondiso kuyalungiswa, kwaye ukusilela koqulunqo ngeCONFIG_CFI=yy CONFIG_LTO_CLANG_FULL=y kuyaphetshwa.
Ulawulo lwamandla kunye nokusebenza kwiLinux 6.18-rc4
Ukuhlehla kokusebenza kwirhuluneli yemenyu ye-CPUidle ebuyela emva kwi-Linux 6.17 iye yasonjululwa. Umba, ojongwe nguDoug Smythies kwi-Intel Core i5-10600K, ubangele ukusebenza kwehle malunga ne-11% kwimithwalo ethile, kwaye sele ilungisiwe kwi-Git ngexesha lomgqatswa wokukhululwa.
Ukulungiswa, okubhalwe nguRafael Wysocki, kubeka phambili ukungena kwi-polling state ngokuphindaphindiweyo xa i-latency yokuphuma kwimeko yokulala idlula ixesha elilindelekileyo lokungasebenzi. Olu hlengahlengiso lunciphisa ukulinda okungeyomfuneko kwaye lubuyise ukusebenza okulahlekileyo; igcwalisa i Ulungiso lwakutsha nje lweChromebooks kunye ne-Intel uchatshazelwa kolunye ukuhlehla kolawulo lwamandla.
Ezinye iikernel fronts kule RC
Ngaphaya kwe-x86 kunye namandla, uninzi lotshintsho luphinde lube kubalawuli: Imizobo, inethiwekhi kunye nesandi zikhokela indlela Amabala. Kwiindawo ezingahambelani nomqhubi, kukho uhlengahlengiso oluncinci kwi-stack yenethiwekhi, i-SMB/XFS/nfsd, i-sched_ext, kunye neemvavanyo ezongezelelweyo ze-VFIO. Iqela lokulondoloza lichaza olu hlengahlengiso njengento engabalulekanga kunye nemigca embalwa yekhowudi.
Ukufumaneka, uvavanyo kunye nomxholo
Ngale RC4 ikhutshiweyo, inguqulelo yokugqibela ye-6.18 kufuneka ifike ekupheleni kukaNovemba okanye kwiveki yokuqala kaDisemba.
Abo bavavanya i-RC4 kufuneka babeke iliso kumanqaku amaninzi: qinisekisa ukuba akukho zimpazamo xa uqulunqa ne-Clang's CONFIG_CFI kunye ne-LTO, jonga ukulala kunye nokuziphatha kokungenzi nto kwiilaptops, kwaye uqinisekise kwiZen 5 ukuba RDSEED umyalezo ovaliweyo Ivela kwi-dmesg emva kokufaka i-microcode ehambelanayo. Nayiphi na imiba inokuxelwa kwi-LKML okanye umlondolozi wenkqubo engaphantsi echaphazelekayo.
I-Linux 6.18-rc4 ikhula kakuhleYandisa inkxaso ye-Zen 6, ithomalalisa umba we-RDSEED kwi-Zen 5, ilungisa ukuhlehla kwamandla, kwaye ipolishe abaqhubi abaphambili kunye ne-subsystems. Ukuthintela naziphi na iimeko ezingalindelekanga, ishedyuli ihlala ingatshintshi, kwaye iintsuku ezizayo ziya kunikezelwa ekuzinzeni ukulungiswa kakuhle kunye nokusebenza ukulungiselela ukukhululwa okuzinzile.
