Subject: [PATCH v3 6/8] drm/xe/sriov: Move VF bootstrap and query_config to vf_guc_init
Date: Tue, 29 Oct 2024 15:44:10 +0100	[thread overview]
Message-ID: <20241029144412.66081-5-maarten.lankhorst@linux.intel.com> (raw)
In-Reply-To: <20241029144412.66081-1-maarten.lankhorst@linux.intel.com>

We want to split up GUC init to an alloc and noalloc part to keep the
init path the same for VF and !VF as much as possible.

Everything in vf_guc_init should be done as early as possible, otherwise
VRAM probing becomes impossible.
