PXP (Protected Xe Path) is an i915 component, available on GEN12+, that helps to establish the hardware protected session and manage the status of the alive software session, as well as its life cycle. I'm taking over this series from Sean. I've significantly reworked the code since his last revisioni [1], including a different patch split, so I've reset the series revision count. I believe I've addressed most of the pending comments, but please point out aything I've missed. Still RFC for 2 reasons: - mutex usage needs a bit more reworking - very lightly tested [1] https://patchwork.freedesktop.org/series/84620/ Cc: Huang Sean Z <sean.z.huang@xxxxxxxxx> Cc: Gaurav Kumar <kumar.gaurav@xxxxxxxxx> Cc: Chris Wilson <chris@xxxxxxxxxxxxxxxxxx> Cc: Rodrigo Vivi <rodrigo.vivi@xxxxxxxxx> Cc: Joonas Lahtinen <joonas.lahtinen@xxxxxxxxxxxxxxx>
