Subject: [Intel-gfx] [PATCH v6 03/15] drm/i915/pxp: define PXP device flag and kconfig
Date: Wed, 28 Jul 2021 19:00:54 -0700 [thread overview]
Message-ID: <20210729020106.18346-4-daniele.ceraolospurio@intel.com> (raw)
In-Reply-To: <20210729020106.18346-1-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.
