Dezvoltatorii nucleului Linux au anun\u021bat transferul \u00een ramura linux-next, care va fi utilizat\u0103 pentru a forma versiunea 6.12, a modific\u0103rilor finale necesare pentru a compila nucleul cu op\u021biunea PREEMPT_RT, care include instrumente pentru func\u021bionarea \u00een timp real. Dup\u0103 adoptarea modific\u0103rilor \u00een ramura principal\u0103 a nucleului, modul PREEMPT_RT va deveni disponibil pentru arhitecturile X86, ARM64 \u0219i RISC-V. Suportul pentru arhitecturile ARM \u0219i POWERPC va fi ad\u0103ugat ulterior, pentru care nu toate patch-urile au fost \u00eenc\u0103 integrate \u00een nucleu. <\/p>\n

Dezvoltarea implement\u0103rii modului \u00een timp real pentru nucleul Linux a \u00eenceput \u00een 2005, \u00een cadrul proiectului \u201eRealtime-Preempt\u201d (\u201e-rt\u201d) \u0219i, din 2015, este coordonat\u0103 de organiza\u021bia Linux Foundation. P\u00e2n\u0103 acum, implementarea modului PREEMPT_RT a fost livrat\u0103 sub form\u0103 de patch-uri externe, pe baza c\u0103rora anumite distribu\u021bii, cum ar fi RHEL, SUSE \u0219i Ubuntu, au creat edi\u021bii Realtime separate ale produselor lor, cerute \u00een domenii precum sistemele financiare, dispozitivele de procesare a sunetului \u0219i video, avia\u021bia, medicina, robotic\u0103, telecomunica\u021bii \u0219i sisteme industriale, \u00een care este necesar s\u0103 se asigure un timp predictibil de procesare a evenimentelor. <\/p>\n

\u00cen 2019, a \u00eenceput promovarea patch-urilor dezvoltate \u00een PREEMPT_RT pentru a fi integrate \u00een nucleul principal. \u00cen fi\u0219ierul de configurare al nucleului 5.3 a fost ad\u0103ugat op\u021biunea PREEMPT_RT pentru activarea modulului \u00een timp real, dar integrarea modific\u0103rilor necesare pentru func\u021bionarea acesteia s-a \u00eentins pe 5 ani. Acum, acest proces se apropie de final \u0219i, cel mai probabil, deja \u00een versiunea 6.12 nucleul va putea fi compilat \u00een modul PREEMPT_RT f\u0103r\u0103 aplicarea de patch-uri suplimentare. <\/p>\n

Ultima func\u021bionalitate lips\u0103 din nucleu, care nu permitea activarea modulului PREEMPT_RT, a fost suportul pentru ie\u0219irea atomic\u0103 neblocat prin func\u021bia printk. Aceast\u0103 capacitate a fost acum acceptat\u0103 \u00een ramura linux-next. De asemenea, integrarea \u00een ramura linux-next a\u0219teapt\u0103 implementarea consolei atomice \u0219i neblocate pentru driverul UART 8250, f\u0103r\u0103 de care ie\u0219irea urgent\u0103 \u00een consol\u0103 din cod \u00een cadrul atomic este deocamdat\u0103 dezactivat\u0103.
