category: feature
bugzilla: https://bugzilla.openeuler.org/show_bug.cgi?id=19
CVE: NA

----------------------------------------------------------------

Some ACPI devices need to issue dma requests to access
the reserved memory area.BIOS uses the device scope type
ACPI_NAMESPACE_DEVICE in RMRR to report these ACPI devices.
This patch add support for detecting ACPI devices in RMRR and in
order to distinguish it from PCI device, some interface functions
are modified.

This patch was submitted to mainline kernel but not accepted by upstream
maintainer whose reason is "As I explained in the previous reply, RMRRs
were added as work around for certain legacy device and we have been
working hard to fix those legacy devices so that RMRR are no longer
needed. Any new use case of RMRR is not encouraged".

VT-D 1.3/2.5/3.0 Spec have this case's specification, We think this
Intel driver should support this case too.
