Ukukhululwa kweKernel Linux 6.12 ngenkxaso yeRealtime

Emva kweenyanga ezimbini zophuhliso, uLinus Torvalds wayikhulula i-kernel. Linux 6.12. Phakathi kotshintsho oluphawulekayo: ukukwazi ukuvula imo yeRealtime, i-sched_ext yokwenza ii-CPU scheduler nge-eBPF, i-QR code output kwiimeko ezingxamisekileyo, i-Device Memory TCP mechanism, i-SCHED_DEADLINE server resource reservation mechanism, ukuphuculwa kwe-EEVDF task scheduler, i-IPE module yokuseta imigaqo-nkqubo yokuthembeka.

Inguqulelo entsha ibandakanya ukulungiswa kwe-14607 ukusuka kubaphuhlisi be-2167, ubungakanani be-patch yi-37 MB (utshintsho oluchaphazelekayo lweefayile ze-13087, i-507913 imigca yekhowudi yongezwa, i-234083 imigca yacinywa). Ukukhutshwa kokugqibela kunezilungiso ze-15130 ezivela kubaphuhlisi be-2078, ubungakanani be-patch babuyi-85 MB (kwi-kernel ye-6.10 i-patch yayingu-41 MB ngobukhulu). Ngokumalunga ne-45% yazo zonke iinguqu ezifakwe kwi-6.12 zihambelana nabaqhubi besixhobo, malunga ne-12% yeenguqu zihambelana nokuhlaziya ikhowudi ethile kwi-architectures ye-hardware, i-13% inxulumene ne-stack networking stack, i-6% inxulumene neenkqubo zefayile, kunye ne-3% zinxulumene ne-kernel yangaphakathi yendlela esezantsi.

Izinto ezintsha eziphambili kwi-kernel 6.12:

• Iinkonzo zememori kunye nenkqubo
  • Ukukwazi ukwakha i-kernel ngokhetho lwe-PREEMPT_RT ngaphandle kwee-patches ezongezelelweyo zokusebenza ngexesha langempela ngoku ziyafumaneka. Uphawu lokugqibela lwe-kernel olungekhoyo oluthintele imo ye-PREEMPT_RT ekubeni isebenze yayikukuxhasa ukuphuma kwe-atomic okungavimbiyo ngomsebenzi we-printk, oqukwe nakwi-kernel. Inkxaso ye-PREEMPT_RT iyafumaneka kwi-architectures ze-x86, x86_64, ARM64, kunye ne-RISC-V. Ukuza kuthi ga ngoku, ukuphunyezwa kwemo ye-PREEMPT_RT kubonelelwe ngendlela yee-patches zangaphandle, ezisasazwayo, njenge-RHEL, SUSE, kunye Ubuntu, benze iinguqulelo ezahlukeneyo zeRealtime zeemveliso zabo, ezifunwa kakhulu kwiindawo ezifana neenkqubo zemali, izixhobo zokucubungula iaudio nevidiyo, iinqwelomoya, amayeza, iirobhothi, unxibelelwano kunye neenkqubo zoshishino, apho kuyimfuneko ukuqinisekisa ixesha eliqikelelweyo lokucubungula iziganeko.
  • Indlela yokusebenza "ye-sched_ext" (SCX) yongezwe, nto leyo evumela ukusetyenziswa kwe-eBPF ukwenza ii-CPU scheduler ezigubungela phantse zonke iinkalo zokuhlela imisebenzi kunye nokwabiwa kwezixhobo zeCPU. Ezi scheduler zinokulayishwa ngokuguquguqukayo kwaye zisetyenziswe ngaphakathi kwi-kernel. Linux в umatshini wenyani i-eBPF. Indlela ye-sched_ext yenza kube lula ukudalwa kwabacwangcisi bemisebenzi ethile, ivumela uvavanyo ngeendlela ezahlukeneyo zokucwangcisa kunye namaqhinga, kwaye ivumela ukudalwa ngokukhawuleza kweeprototypes ezisebenzayo kunye nokutshintshwa kwabacwangcisi kwiziseko zophuhliso lwemveliso. Umzekelo, usebenzisa i-sched_ext, ungenza umcwangcisi oqwalasela iinkcukacha zesicelo esithile kwaye utshintshe ngokuguquguqukayo isicwangciso saso sokucwangcisa ngokuxhomekeke kwimeko yenkqubo kunye nezinye izinto.
  • Ukuqulunqwa kubandakanya inxalenye eseleyo yeepatches eziyimfuneko ekusebenzeni kwe-SCHED_DEADLINE indlela yomncedisi, oyisombulula ingxaki yokusetyenziswa kakubi kwezixhobo ze-CPU ngemisebenzi eqhelekileyo xa i-CPU ilawulwa yimisebenzi ephambili (yexesha langempela). Ukuthintela i-CPU monopolization, i-kernel ngaphambili yayisebenzisa i-Realtime throttling mechanism, eyazama ukugcina i-5% yemisebenzi ephambili ephantsi, ishiya i-95% yexesha lemisebenzi yexesha langempela. Lo matshini ushiye okuninzi okufunwayo, kuba imisebenzi eqhelekileyo kwiimeko ezininzi ayizange ifumane ixesha elaneleyo leprosesa. SCHED_DEADLINE iseva isebenzisa indlela yogcino lwesixhobo esebenza ngokufanelekileyo.
  • Ukudityaniswa kwe-EEVDF (uMhla wokuQala oFanelekileyo wokuQala wokuQala) umcwangcisi womsebenzi ugqityiwe, owathatha indawo yoMcwangcisi weCFS (uMcwangcisi oLungileyo ngokuPheleleyo), obonelelwe ngokuqala ngekernel 2.6.23. Xa ukhetha inkqubo elandelayo yokudlulisa ukwenziwa, umcwangcisi omtsha uthathela ingqalelo iinkqubo ezingakhange zifumane izixhobo ezaneleyo zeprosesa okanye zifumene isixa esikhulu esingasifanelanga sexesha lomqhubekekisi. Kwimeko yokuqala, ukudluliselwa kolawulo kwinkqubo kunyanzeliswa, kwaye okwesibini, ngokuchaseneyo, ihlehlisiwe. Umcwangcisi omdala we-CFS wasebenzisa i-heuristics kunye nokulungiswa kakuhle ukuchonga iinkqubo ezifuna ingqalelo ekhethekileyo, ngelixa umcwangcisi omtsha ezilandelela ngokucace ngakumbi kwaye akafuni ukulungiswa kakuhle. I-EEVDF ilindeleke ukuba icuthe ukulibaziseka kwimisebenzi iCFS eye yaneengxaki zokucwangcisa.
  • Kwisiphatho sikaxakeka se-kernel - I-DRM Panic, esebenzisa i-DRM (uMphathi oBonelela ngokuthe ngqo) isistim esezantsi yokubonisa ingxelo ebonwayo kwisimbo "sesikrini esiluhlaza sokufa", ukukwazi ukubonisa uphawu kunye nekhowudi ye-QR ngengxelo ye-kmsg isikrini xa imeko kaxakeka yongeziwe. Ekubeni kuphela i-2953 bytes engena kwikhowudi ye-QR, ukhetho lwe-DRM_PANIC_SCREEN_QR_CODE_URL lunikiwe, apho ingxelo ye-kmsg ixinzelelwe kusetyenziswa i-zlib kwaye iqhotyoshelwe njengepharamitha kwi-URL, evumela malunga ne-40 bytes ukuba idluliselwe ngekhowudi ye-V7500 QR. Xa ukwakhiwa kweepakethe nge-kernel, ukuhanjiswa kunokusetha i-URL yesiseko ye-URL, eya kubavumela ukuba bahambe baye kwiphepha lokunika ingxelo yengxaki. Ukukhetha ifomati yekhowudi yeQR, useto lwe-DRM_PANIC_SCREEN_QR_VERSION lunikiwe.
