Hi Rodrigo,
I made the modification as below according to Chris and your suggestion, will
reflect at rev20. All my comments (// sean: ...) the won't be checked in.
This change can address part of the comment Chris provided. But please let me
go through the remaining comments at rev19 first.
So I think the define GEN12_KCR_SIP should stay in intel_pxp_arb.c since it's
no shared users.
But anyway please let me know if you insist to move it to i915_reg.h

Sean

Implement the functions to allow PXP to send a GPU command, in
order to terminate the hardware session, so hardware can recycle
this session slot for the next usage.

Implement the intel_pxp_gem_object_status() to allow i915 display
querying the current PXP session state. In the design, display
should not perform protection flip on the protected buffers if
there is no PXP session alive.

Teardown is triggered when the display topology changes and no

all the encryption keys for display. So as a result, PXP should
