Hi Leo,
There are two issues here.
This change fixing the Crash while secure playback and we see below error:

Other PDs/PTs allocation should just use the same xcp_id as that

~0 as no xcp partition is used in several places, so improve its
definition by a macro for code consistency.

Recent code set xcp_id stored from file private data when opening
device to amdgpu bo for accounting memory usage etc, but not all
VMs are attached to this fpriv structure like the vm cases in
amdgpu_mes_self_test, otherwise, KASAN will complain below out
of bound access. And more importantly, VM c
file_priv needs to be setup firstly, otherwise, root PD
will always be allocated on partition 0, even if opening
the device from other partitions.
