I guess this means that Linux does not currently use this interface. I think I remember that Linux implements a utility module with an interface something like "acpi_evaluate_integer", and a couple more. Perhaps acpi_evaluate_buffer already exists, you could use that. >-----Original Message----- >From: linux-acpi-owner@xxxxxxxxxxxxxxx [mailto:linux-acpi- >owner@xxxxxxxxxxxxxxx] On Behalf Of Kenji Kaneshige >Sent: Thursday, February 05, 2009 9:43 PM >To: Moore, Robert >Cc: Alex Chiang; Jesse Barnes; linux-pci@xxxxxxxxxxxxxxx; linux acpi; >Andrew Patterson >Subject: Re: [PATCH 1/2] PCI/ACPI: move _OSC code to pci_root.c > >Moore, Robert wrote: >> The acpi_evaluate_object_typed interface automatically handles the two >error cases you check for: >> >> 1) Checks for the case where no object is returned >> 2) Checks for the correct return object type (buffer in this case) >> >> Use of this interface would simplify and shrink the code. >> > >Sounds good to me, but I have a question. > >The acpi_evaluate_object_typed() function seems to be compiled >only when ACPI_FUTURE_USAGE is defined.
