The value shown by power1_max_interval in millisec is essentially:
((1.x * power(2,y)) * 1000) >> 10
Where x and y are read from a HW register. On ATSM, x and y are 0 on
power-up so the value shown is 0.
Writes of 0 to power1_max_interval had previously been disallowed to avoid

Add GSC engine based method for sending PXP firmware packets

Use the newly added helpers to populate the GSC-CS memory

On legacy platforms, KCR HW enabling is done at the time the mei
component interface is bound. It's also disabled during unbind.
However, for MTL onwards, we don't depend on a tee component
to start sending GSC-CS firmware messages.
Thus, immediately enable (or disable) KCR HW on PXP's init,

by different i915 callers:

This series enables PXP on MTL. On ADL/TGL platforms, we rely on

That interface is used to create and teardown the PXP ARB session.
PXP ARB session is created
For MTL, the PXP back-end transport uses the GSC engine to submit
HECI packets through the HW to the GSC firmware for PXP arb
session management. This submission uses a non-priveleged
batch buffer, a buffer for the command packet and of course
a context targeting the GSC-CS.
