Fix para SATA AHCI lento

[oldnapalm]

Fix para placas que apresentam baixa performance dos HDs SATA quando no modo AHCI (outros HDs que não o do sistema). Consiste em passar os IRQs dos devices RTC0 e TMR para o device HPET (opcional mas recomendado) e liberar o IRQ do device PIC para ser usado pela controladora SATA (esta é a "chave" do fix). Testado numa ASUS Rampage II Extreme.

Hola,

 

Estoy teniendo problemas a la hora de editar y compilar mi DSDT para arreglar el problema de IRQ que has solucionado.

 

Tambien tengo el problema de que mis discos SATA AHCI son muy lentos.

Podrias ayudarme? Muchas Gracias!

 

Hi,

 

Im having some problem when editing and compile my DSDT file to fix the IRQ problem you solved.

I have too very slow SATA AHCI issue.

 

Could you help me please? Thank you!
