Hi Rafael

Thanks,

I  am testing ZPODD function ,for Linux ZPODD kernel,

This is not a mainline code, however, is it?

if _PRW method is removed at  BIOS ACPI DSDT codes, ZPODD work normally.
but, if _PRW method is added at BIOS ACPI DSDT codes,ZPODD can't be
wakeup when ZPODD state is suspend.
I'am not sure that Linux ZPODD whether is using _PRW to send wakeup events.

If you're testing Aaron's patches, please talk to Aaron.

Thanks,
Rafael

Hi aaron,ming,linux-acpi

 Is it  whether need support ACPI _PRW method for ZPODD device ?

Yes, it is.

 If BIOS had implemented _PRW method for ZPODD ,
but Linux kernel doesn't support  ZPODD _PRW method,ZPODD will can't
run into suspend state.

I'm not sure what you mean.

If we don't use _PRW, the device won't be able to signal wakeup events.

Is there any stories for ZPODD Linux _PRW method ?

All threads related to ZPODD are about that indirectly.

Thanks,
Rafael
