Subject: [Devel] Error in documentation of AcpiOsDerivePciId?

Hi list,
According to the ACPICA Programmer Reference, the function
AcpiOsDerivePciId takes as arguments:
AcpiOsDerivePciId(
ACPI_HANDLE DeviceHandle
ACPI_HANDLE PciRegionHandle
ACPI_PCI_ID **PciId)
with:
- DeviceHandle: a handle to the PCI device.
- PciRegionHandle: a handle the PCI configuration space operation
region.
However, the only call to AcpiOsDerivePciId in the ACPICA code, in
events/evrgnini.c, is:
AcpiOsDerivePciId (PciRootNode, RegionObj->Region.Node, &PciId);
Moreover, the file include/acpiosxf.h contains:
/*
* Interim function needed for PCI IRQ routing
*/
void
AcpiOsDerivePciId(
ACPI_HANDLE Rhandle,
ACPI_HANDLE Chandle,
ACPI_PCI_ID **PciId);
So it seems to me that the correct arguments for AcpiOsDerivePciId are:
AcpiOsDerivePciId(
ACPI_HANDLE PciRootHandle
ACPI_HANDLE DeviceHandle
ACPI_PCI_ID **PciId)
with:
- PciRootHandle: a handle the PCI root bridge upstream of the PCI
device (or to the name space root node if no
PCI root bridge was found in the ancestors).
- DeviceHandle: a handle to the PCI device.
Is that correct?
Thanks for your help,
Grégoire
