NAME
cxl-free-dpa - release device-physical address space
SYNOPSIS
cxl free-dpa <mem0> [<mem1>..<memN>] [<options>]
The CXL region provisioning process proceeds in multiple steps. One of the steps is identifying and reserving the DPA span that each member of the interleave-set (region) contributes in advance of attaching that allocation to a region. For development, test, and debug purposes this command is a helper to find the last allocated decoder on a device and zero-out / free its DPA allocation.
