Linux 6.13-rc3 tuumase on muudatus, mis k\u00f5rvaldab j\u00f5udluse regressiooni KVM h\u00fcperviisoris, mis on seotud CPUID kutsete aeglase t\u00f6\u00f6tlemisega uutel CPU-del. N\u00e4iteks Intel Emerald Rapids CPU-de puhul toimub CPUID operatsioon 3-4 korda aeglasemalt kui Intel Skylake CPU-del. Selline erip\u00e4ra on viinud KVM h\u00fcperviisori j\u00f5udluse languseni, mis kasutab CPUID protsessori oleku salvestamise ja taastamise protsessis igal korral, kui kontroll antakse virtuaalmasinale, kui kasutusel on siseriiklik virtualiseerimine. Probleemi lahendamiseks on 6.13 tuumavarras vastu v\u00f5etud k\u00e4rbitud pat\u0161, mis v\u00f5imaldab kuni 40% v\u00f5rra v\u00e4hendada operatsiooni aega isegi SkyLake seeria CPU-del t\u00e4nu CPUID vahem\u00e4lule. Kern 6.14-s on oodata pat\u0161i t\u00e4ielikku versiooni, mis parandab t\u00e4iendavalt j\u00f5udlust. <\/p>\n
Lisaks tasub m\u00e4rkida arutelu Linuxi tuuma arendajate meililisti peatamise kohta 32-bitiste s\u00fcsteemide toetamiseks KVM h\u00fcperviisorist. KVM<\/a>. Alguses oli tuuma jaoks ette n\u00e4htud plaastr, mis eemaldab KVM virtualiseerimise toe x86-32 platvormil. Vastuseks esitati mure, et x86-32 toe s\u00e4ilitamine v\u00f5iks olla kasulik host-re\u017eiimi t\u00f6\u00f6 testimiseks 32-bitistel s\u00fcsteemidel, kuna tuumas on lisaks x86-32-le veel kolm 32-bitist arhitektuuri, mida KVM toetab. Vastuseks esitati veel \u00fcks plaastr, mis seekord eemaldab KVM-st k\u00f5igi 32-bitiste s\u00fcsteemide toe. <\/p>\n Soov vabaneda 32-bitiste s\u00fcsteemide toest on tingitud sellest, et isegi massiliselt kasutatavatel 32-bitistel ARM protsessoritel, nagu ARM Cortex A7, ei ole virtualiseerimist arendatud. virtuaalmasinad<\/a> 32-bitistes ARM s\u00fcsteemides oli virtualiseerimise kasutamine niiv\u00f5rd haruldane, et nende s\u00fcsteemide toetus KVM-is eemaldati 2020. aastal ning see ei tekitanud vastuseisu. Toodud on, et \u00fclej\u00e4\u00e4nud 32-bitiseid s\u00fcsteeme m\u00f5jutavad muudatused puudutavad vaid eksootilisi platvorme, mida ei ole pikka aega praktikas kasutatud v\u00f5i mis ei ole kunagi olnud populaarsed. Plaastr toob esile protsessorid, nagu Intel Core Duo\/Silverthorne, PowerPC e300\/e500\/e600 ja MIPS P5600. Plaastr on avaldatud kui RFC, see t\u00e4hendab, et see on arutamiseks esitatud. \u0412 \u0441\u043e\u0441\u0442\u0430\u0432 \u044f\u0434\u0440\u0430 Linux 6.13-rc3 \u043f\u0440\u0438\u043d\u044f\u0442\u043e \u0438\u0437\u043c\u0435\u043d\u0435\u043d\u0438\u0435, \u0443\u0441\u0442\u0440\u0430\u043d\u044f\u044e\u0449\u0435\u0435 \u0440\u0435\u0433\u0440\u0435\u0441\u0441\u0438\u044e \u043f\u0440\u043e\u0438\u0437\u0432\u043e\u0434\u0438\u0442\u0435\u043b\u044c\u043d\u043e\u0441\u0442\u0438 \u0432 \u0433\u0438\u043f\u0435\u0440\u0432\u0438\u0437\u043e\u0440\u0435 KVM, \u0441\u0432\u044f\u0437\u0430\u043d\u043d\u0443\u044e \u0441 \u043c\u0435\u0434\u043b\u0435\u043d\u043d\u043e\u0439 \u043e\u0431\u0440\u0430\u0431\u043e\u0442\u043a\u043e\u0439 \u0432\u044b\u0437\u043e\u0432\u043e\u0432 CPUID \u043d\u0430 \u043d\u043e\u0432\u044b\u0445 CPU, \u043d\u0430\u043f\u0440\u0438\u043c\u0435\u0440, \u043d\u0430 CPU Intel Emerald Rapids \u043e\u043f\u0435\u0440\u0430\u0446\u0438\u0438 c CPUID \u0432\u044b\u043f\u043e\u043b\u043d\u044f\u044e\u0442\u0441\u044f \u0432 3-4 \u0440\u0430\u0437\u0430 \u043c\u0435\u0434\u043b\u0435\u043d\u043d\u0435\u0435, \u0447\u0435\u043c \u043d\u0430 CPU Intel Skylake. \u041f\u043e\u0434\u043e\u0431\u043d\u0430\u044f \u043e\u0441\u043e\u0431\u0435\u043d\u043d\u043e\u0441\u0442\u044c \u043f\u0440\u0438\u0432\u0435\u043b\u0430 \u043a \u0441\u043d\u0438\u0436\u0435\u043d\u0438\u044e \u043f\u0440\u043e\u0438\u0437\u0432\u043e\u0434\u0438\u0442\u0435\u043b\u044c\u043d\u043e\u0441\u0442\u0438 \u0433\u0438\u043f\u0435\u0440\u0432\u0438\u0437\u043e\u0440\u0430 KVM, \u043a\u043e\u0442\u043e\u0440\u044b\u0439 \u0438\u0441\u043f\u043e\u043b\u044c\u0437\u0443\u0435\u0442 CPUID \u0432 \u043f\u0440\u043e\u0446\u0435\u0441\u0441\u0435 \u0441\u043e\u0445\u0440\u0430\u043d\u0435\u043d\u0438\u044f […]<\/p>\n","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[702],"tags":[],"class_list":["post-120994","post","type-post","status-publish","format-standard","hentry","category-novosti-interneta"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\n","aioseo_head_json":{"title":"\ud83e\udd47KVM: j\u00f5udluse regressioonid ja arutelu 32-bitiste s\u00fcsteemide toe \u00fcle | ProHoster","description":"Linux 6.13-rc3 tuuma sisaldab muudatust, mis k\u00f5rvaldab KVM h\u00fcperviisori j\u00f5udluse regressiooni, mis on seotud uute protsessorite, n\u00e4iteks Intel Emerald Rapids, aeglase CPUID kutsete t\u00f6\u00f6tlemisega; CPUID operatsioonid toimuvad selles kuni 3-4 korda aeglasemalt kui Intel Skylake protsessoritel.
