From: François Tigeot Date: Sat, 8 Dec 2012 22:31:50 +0000 (+0100) Subject: agp: A rewrite of the i810 bits of the driver X-Git-Tag: v3.4.0rc~705 X-Git-Url: https://gitweb.dragonflybsd.org/dragonfly.git/commitdiff_plain/a904aa533e5951e599633089e7301593b3abc60c?hp=973817806f8a66cbe9e64caee285ece49873e7bc agp: A rewrite of the i810 bits of the driver New driver supports operations required by GEMified i915.ko. It also attaches to SandyBridge and IvyBridge CPU northbridges now.
