Subject: [PATCH 0/5] bridges without VGA support
Date: Wed, 18 Feb 2026 02:04:14 +0900 [thread overview]
Message-ID: <20260217170419.236739-1-Simon.Richter@hogyros.de> (raw)
Hi,
this allows bridges to refuse forwarding VGA, and reports this upwards as an
error, because we cannot set up valid decoding for the requested device in this
case.
I think it should be fine to leave VGA forwarding enabled on lower bridges if a
bridge closer to the root refused to enable forwarding, because no accesses can
reach there anyway.
