There is some pressure to remove AGP entirely and rely on PCI mappings instead (which are slower IIRC but may possibly still have decent performance with modern object management techniques that the drivers have. Will need testing.) AGP is kind of a weird case because of what it is and how it works, and how it interacts with everything else. > WARNING: Device "consolectl" is Giant locked and may be deleted before > FreeBSD 13.0. Might need to migrate some bits over to vt at some point. -- Brandon Bergren bdragon@FreeBSD.org
