ACPI - how to get ACPI_REGS_INTERFACE_STANDARD ?

NTDEV

Hello people,

I really need ACPI guru :slight_smile:
Could anybody help me to acquire the interface
ACPI_REGS_INTERFACE_STANDARD from ACPI driver ? What I need to do to get
this structure ? I build the IRP with IRP_MN_QUERY_INTERFACE, send it to
acpi driver, but get empty structure :(, fill of zeroes.
From the other hand, may be there are other ways to access PM1 ACPI
control register ?

Thanks in advance

That’s an interface intended to be sent from ACPI to the HAL, not from a
driver to ACPI, which is why you didn’t get a response. There is no safe
way to share these registers with ACPI.
