Limpando uma bagunça: o Kernel Linux 6.9 provavelmente irá refazer o código de topologia da CPU x86

 

Uma possível reescrita do texto com outras palavras e aumentando as visualizações é:

O Kernel Linux 6.6 está para facilitar a ativação do SMT parcial para o POWER

 

O hardware IBM POWER oferece suporte ao Simultaneous Multi-Threading (SMT) de até 4 ou até mesmo 8 vias, permitindo a execução de múltiplos threads por núcleo. Enquanto o SMT em processadores Intel/AMD x86_64 é limitado a fornecer apenas um thread adicional por núcleo, os processadores IBM POWER podem explorar ainda mais o potencial do SMT.

O Kernel Linux 6.5 está para melhorar o balanceamento de carga para as CPUs híbridas da Intel

 

Ingo Molnar revelou ontem as atualizações do agendador destinadas à versão 6.5 do kernel Linux. Uma das mudanças mais notáveis no agendador de CPU é a melhoria do balanceamento de carga SMP (Hyper Threading) para os processadores Intel Core de design híbrido, que combinam núcleos P e E.
