Iyafumaneka ngoku uguqulelo I-Linux 6.15-rc2, kwiveki nje enye emva kokuvalwa ngokusemthethweni kwefestile yokudibanisa utshintsho kunye ne umgqatswa wokuqala wokukhululwa. Lo mgqatswa wesibini wokukhupha i-kernel uza neendlela ezahlukeneyo zokulungiswa kwangaphambili eziye zaqokelelwa kwiintsuku ezimbalwa ezidlulileyo, njengenxalenye yomjikelo wesiqhelo wophuhliso lwe-Linux kernel.
U-Linus Torvalds, njengesiqhelo, wayephethe ukwazisa le nguqulo entsha kwaye wathi, nangona ifestile yokudibanisa yayinde kunesiqhelo, Okwangoku yonke into ibonakala iqhelekile.. Inani le uyenza kwaye utshintsho olwenziweyo luhlala luphakathi kwemida yeenkcukacha-manani eziqhelekileyo, kungekho mba umnye ume ngaphandle ngokugqithisileyo kweli nqanaba lokuqala lokukhululwa.
I-Linux 6.15-rc2 yazisa uphuculo kubaqhubi bemizobo: Intel kunye ne-AMD
Enye yeengongoma eziphawulekayo kule nguqulo inento yokwenza ne abaqhubi bemizobo. Kwicala le-AMD, umqhubi we-AMDGPU wongeze inkxaso ye ulawulo lwememori yevidiyo ecacileyo ngokusebenzisa amaqela, umsebenzi othiwa I-DMEM. Oku kudityaniswa ngoku kuvumela ukusetyenziswa kweVRAM ukuba kuthintelwe ziinkqubo ezithile ngokusebenzisa iindlela zolawulo lweqela.
Ukongeza kwinkxaso yeDMEM, umqhubi we-AMD naye ufumene uhlengahlengiso kulawulo lwe-EDP, ukulungiswa kwe-VRAM pinning kwiindawo zokungeniswa kwe-P2P ezinikwe amandla, kunye nokulungiswa kweeprofayili zomsebenzi kunye nokufunyanwa kwe-IP ngaphakathi kwenkqubo yokunikezelwa.
Ngokuphathelele imizobo ye-Intel, Umqhubi weXe ubandakanye ukulungiswa okubalulekileyo kwimiba eqhwanyazayo ebonwe kwimizobo yeMeteor Lake. Ngokukodwa, ukuziphatha kwemigca ye-cache ye-L3 yokufunda kuphela ehambelana nemijelo yejometri iye yalungiswa. Olu hlengahlengiso lujolise ekupheliseni ukudanyaza okukruqulayo okuthe kwaxelwa ngabanye abasebenzisi kwiinkqubo ezinolu lwakhiwo.
Yongezwe kwakhona isazisi isixhobo esitsha 0xE211 ehambelana nekamva "I-Battlemage" ye-architecture, ngokulindela ukuqaliswa kwayo ngokusemthethweni, kwaye izilungiso ezininzi ezincinci ziye zasetyenziswa kwezinye iinqununu zegraphics ezifana ne-AMDKFD (yekhompyutheni) kunye nomqhubi we-Intel IVPU NPU, ukuphucula inkxaso yokumisa kunye nokuqalisa ukusebenza.
Uhlaziyo kunye nokucoca kwiSpecter RSB yokunciphisa
Enye yeentsika zale nguqulelo Ukuphuculwa kwamanyathelo okunciphisa iSpecter RSB (Buyisela i-Stack Buffer), ubuthathaka obukhoyo kwi-Intel kunye ne-AMD processors. Umsebenzi ukhokelwa ikakhulu ngabaphuhlisi be-Red Hat, abaye bachitha iinyanga ezininzi befezekisa ukuphathwa kwe-kernel yale milinganiselo.
Phakathi kwezilungiso eziphambili yi ukulungiswa kwifowuni a indirect_branch_prediction_barrier(), kunye nokupheliswa kokuzalisa i-RSB zombini kumatshini wokuphuma wenyani (VMEXIT) kunye notshintsho kwimeko ukuba ukusetyenziswa kuyenziwa eIBRS kunye neeRetpolines.
Ukongeza kwikhowudi, Amaxwebhu amatsha athile afakiwe esishwankathela ngokucacileyo izicwangciso zokunciphisa zangoku, ukwahlula iimeko zokuhlaselwa ngokohlobo lweprosesa kunye nolwakhiwo. Olu xwebhu lujonge ukusebenza njengesalathiso kubaphuhlisi abanokufuna ukujongana nobuthathaka bexesha elizayo kulo mmandla.
Ukugcinwa ngokubanzi kunye novavanyo lwangethuba
Njengaye wonke umgqatswa okhutshwe kwangoko, I-Linux 6.15-rc2 iphinda ifake ii-tweaks ezincinci isasazwe kuyo yonke ikhowudi, kubandakanywa iindawo ezifana neyona nto iphambili, iinkqubo zefayile, inethiwekhi, amaxwebhu, kunye nezakhiwo ezithile. Njengoko kubonisiwe, malunga ne-25% Iipetshi zale veki zilungiselelwe ukuzivavanya, nto leyo engaqhelekanga kodwa engaqhelekanga ngeli nqanaba.
Ngokunxuseneyo, abanye abasebenzisi kunye nabaphuhlisi sele beqalisile olwabo uvavanyo lwale nguqulo yekernel. Kolunye lwezi mvavanyo, olwenziwa kwi-a ILenovo ThinkPad T14s Gen 6 ixhotyiswe ngeprosesa AMD Ryzen AI 7 PRO 360 (I-Zen 5, i-Strix Point), ngaphezu kwe-benchmarks ye-60 yavavanywa phakathi kwe-Linux 6.14 kunye nemeko yangoku ye-6.15. Iziphumo azibonakalisi zintlukwano ezibalulekileyo, ngaphandle kophuculo oluthile kwi-synthetic microbenchmarks ezifana ne-Stress-NG. Kuvavanyo lwehlabathi lokwenyani, uninzi lweemetriki zahlala ngaphakathi komda wempazamo eqhelekileyo.
Ezi zinto zifunyanisiweyo zakwangoko zomeleza uluvo lokuba akukho ukuhlehla kunzulu okuthe kwaziswa kweli nqanaba lokuqala, kwaye oko inkxaso ye-kernel kuba iqonga elitsha le-AMD sele likhulile.
Lo mgqatswa wesibini wokukhutshelwa kweLinux 6.15 ubonelela ngokujonga okokuqala ukuba lo mjikelo wophuhliso uvela njani, nge uphuculo lobugcisa olufanelekileyo kwiindawo eziphambili ezifana nokhuseleko kunye nokuphathwa kwe-GPU. Nangona kusekho indlela ende ekufuneka ihanjwe ngaphambi kokukhululwa kwayo okuzinzile, okucwangciselwe ukuphela kukaMeyi, uphuhliso lwangoku lubonisa ukuqhubela phambili okuzinzileyo, okulungiselelwe ukulungiswa kwebug kunye nokudityaniswa kweempawu ezintsha.
