Foi publicado o lan\u00e7amento da ferramenta auto-cpufreq 3.0.0, destinada \u00e0 otimiza\u00e7\u00e3o autom\u00e1tica da velocidade de opera\u00e7\u00e3o da CPU e do consumo de energia no sistema. A ferramenta monitora o estado da bateria do laptop, a carga da CPU, a temperatura da CPU e a atividade no sistema, e dependendo da situa\u00e7\u00e3o e das op\u00e7\u00f5es escolhidas, ativa dinamicamente modos de economia de energia ou de alta performance. \u00c9 compat\u00edvel com dispositivos que possuem processadores Intel, AMD e ARM. Um interface gr\u00e1fica baseada em GTK ou uma ferramenta de linha de comando pode ser utilizada para gerenciar. O c\u00f3digo foi escrito em Python e \u00e9 distribu\u00eddo sob a licen\u00e7a LGPLv3. <\/p>\n

Entre os recursos suportados est\u00e3o: monitoramento da frequ\u00eancia, carga e temperatura da CPU, regula\u00e7\u00e3o da frequ\u00eancia e dos modos de consumo de energia da CPU com base na carga da bateria, temperatura e carga do sistema, otimiza\u00e7\u00e3o autom\u00e1tica do desempenho da CPU e do consumo de energia. O auto-cpufreq pode ser utilizado para prolongar o tempo de uso aut\u00f4nomo de laptops sem reduzir constantemente certas funcionalidades. Ao contr\u00e1rio da ferramenta TLP, o auto-cpufreq n\u00e3o s\u00f3 permite definir modos de economia de energia durante a opera\u00e7\u00e3o aut\u00f4noma do dispositivo, mas tamb\u00e9m ativar temporariamente o modo alto desempenho<\/a> (turbo boost) ao detectar aumento na carga do sistema. <\/p>\n

Na nova vers\u00e3o, foi implementada a possibilidade de ativar ou desativar for\u00e7adamente o modo turbo do CPU (turbo boost) atrav\u00e9s da interface gr\u00e1fica e da linha de comando («auto-cpufreq —turbo={never|always|auto}»), independentemente do n\u00edvel de carregamento da bateria. Tamb\u00e9m foi adicionado ao arquivo de configura\u00e7\u00e3o o par\u00e2metro battery_device para selecionar a bateria, caso a detec\u00e7\u00e3o autom\u00e1tica padr\u00e3o esteja incorreta (as baterias dispon\u00edveis podem ser visualizadas no diret\u00f3rio \/sys\/class\/power_supply\/). Um exemplo de arquivo de configura\u00e7\u00e3o para Nixos foi inclu\u00eddo.

\"Lan\u00e7amento<\/center> <\/p>\n

Adicionalmente, destaca-se o lan\u00e7amento da ferramenta TLP 1.9.1, destinada \u00e0 otimiza\u00e7\u00e3o autom\u00e1tica do consumo de energia e ao prolongamento do tempo de uso aut\u00f4nomo de laptops. Al\u00e9m de gerenciar os modos de economia de energia da CPU, a ferramenta suporta a ativa\u00e7\u00e3o e desativa\u00e7\u00e3o adaptativa de Bluetooth, NFC e Wi-Fi. O c\u00f3digo do projeto foi escrito em Shell e Python e \u00e9 distribu\u00eddo sob a licen\u00e7a GPLv2. <\/p>\n

A vers\u00e3o 1.9 se destaca pela adi\u00e7\u00e3o de um processo em segundo plano opcional, tlp-pd, que permite a comuta\u00e7\u00e3o entre tr\u00eas perfis de consumo de energia \u2014 performance, balanced e power-saver. O processo em segundo plano pode ser utilizado como substituto do servi\u00e7o power-profiles-daemon e suporta a API D-Bus, que \u00e9 utilizada para alternar perfis no GNOME, KDE e Cinnamon. A ferramenta tlpctl tamb\u00e9m foi inclu\u00edda para alternar perfis a partir da linha de comando e iniciar aplicativos espec\u00edficos com um perfil definido. <\/p>\n

Na vers\u00e3o corretiva 1.9.1 do TLP, foi corrigida uma vulnerabilidade (CVE-2025-67859) no novo processo em segundo plano tlp-pd, que permitia contornar a verifica\u00e7\u00e3o de autentica\u00e7\u00e3o no servi\u00e7o Polkit e realizar a\u00e7\u00f5es no tlp-pd que exigem privil\u00e9gios de administrador. O processo tlp-pd \u00e9 executado com privil\u00e9gios de root e aceita solicita\u00e7\u00f5es via D-Bus. Parte das solicita\u00e7\u00f5es pode ser enviada por quaisquer usu\u00e1rios com acesso local autenticado ao sistema (que iniciaram uma sess\u00e3o gr\u00e1fica), enquanto algumas a\u00e7\u00f5es est\u00e3o dispon\u00edveis apenas para o administrador. A vulnerabilidade \u00e9 causada por uma condi\u00e7\u00e3o de corrida, permitindo substituir o processo ap\u00f3s o envio da solicita\u00e7\u00e3o, de forma que o polkit acreditar\u00e1 que a solicita\u00e7\u00e3o foi enviada pelo administrador e n\u00e3o solicitar\u00e1 a senha do administrador.
