Subject: [Intel-gfx] [PATCH v13 03/17] drm/i915/pxp: define PXP device flag and kconfig
Date: Fri, 24 Sep 2021 12:14:38 -0700 [thread overview]
Message-ID: <20210924191452.1539378-4-alan.previn.teres.alexis@intel.com> (raw)
In-Reply-To: <20210924191452.1539378-1-alan.previn.teres.alexis@intel.com>
From: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com>
Ahead of the PXP implementation, define the relevant define flag and
kconfig option.
v2: flip kconfig default to N. Some machines have IFWIs that do not
support PXP, so we need it to be an opt-in until we add support to query
the caps from the mei device.
v10: change comments from "Gen12+" to "Gen12 and newer"
