[PATCH v7 12/12] hw/mem/cxl_type3: Allow to release extent superset in Q


From: nifan . cxl
Subject: [PATCH v7 12/12] hw/mem/cxl_type3: Allow to release extent superset in QMP interface
Date: Thu, 18 Apr 2024 16:11:03 -0700

From: Fan Ni <fan.ni@samsung.com>

Before the change, the QMP interface used for add/release DC extents
only allows to release an extent whose DPA range is contained by a single
accepted extent in the device.

With the change, we relax the constraints.  As long as the DPA range of
the extent is covered by accepted extents, we allow the release.
