Subject: [PATCH 0/2] drm/probe_helper, i915: Validate MST modes against PBN limits
Date: Tue, 26 May 2020 14:23:08 -0400 [thread overview]
Message-ID: <20200526182313.4005-1-lyude@redhat.com> (raw)
Something we've been missing for a while with drivers that support MST
is being able to prune modes that can't be set due to bandwidth
limitations. So, let's go ahead and add that. This also adds a new hook
that was needed, mode_valid_ctx, so that we can grab additional locks as
needed when validating modes.
