A Intel disponibilizou os c\u00f3digos fontes do firmware para o bloco PSE (Programmable Services Engine), que come\u00e7ou a ser fornecido em processadores da fam\u00edlia Elkhart Lake, como o Atom x6000E, otimizados para uso em dispositivos de internet das coisas. O c\u00f3digo est\u00e1 liberado sob a licen\u00e7a Apache 2.0. <\/p>\n

O PSE \u00e9 um n\u00facleo adicional de processador ARM Cortex-M7, operando em modo de baixo consumo de energia. O PSE pode ser utilizado para executar funcionalidades de controlador embutido, processar dados de sensores, organizar controle remoto, delegar opera\u00e7\u00f5es de rede e realizar tarefas especializadas de forma independente. <\/p>\n

Inicialmente, este n\u00facleo era gerenciado por meio de firmware fechado, o que impedia a implementa\u00e7\u00e3o do suporte a chips com PSE em projetos abertos, como o CoreBoot. Em particular, a aus\u00eancia de informa\u00e7\u00f5es sobre a gest\u00e3o de baixo n\u00edvel do PSE gerava descontentamento e preocupa\u00e7\u00f5es com seguran\u00e7a, devido \u00e0 impossibilidade de verificar as a\u00e7\u00f5es do firmware. No final do ano passado, desenvolvedores do projeto CoreBoot publicaram uma carta aberta \u00e0 Intel solicitando a libera\u00e7\u00e3o do c\u00f3digo do firmware do PSE, e, em \u00faltima an\u00e1lise, a empresa atendeu \u00e0s necessidades da comunidade. <\/p>\n

No reposit\u00f3rio com o firmware do PSE, tamb\u00e9m foram publicados os testes de c\u00f3digo-fonte das utilidades para desenvolvedores e exemplos de aplica\u00e7\u00f5es que podem ser executadas no lado do PSE, componentes para a execu\u00e7\u00e3o do RTOS Zephyr, firmware ECLite com implementa\u00e7\u00e3o de funcionalidades de controlador embutido, uma implementa\u00e7\u00e3o de refer\u00eancia da interface de controle OOB (Out-of-Band) e um framework para desenvolvimento de aplica\u00e7\u00f5es.
