From cda173806644d2af22ffd9896eed8ef99b97d356 Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Sun, 10 Jul 2005 17:31:26 +1000 Subject: drm: add test for AGP devices and driver override for it. Added device_is_agp callback to drm_driver. This function is called by the platform-specific drm_device_is_agp function. Added implementation of this function the the Linux-specific portion of the MGA driver to detect PCI G450 cards. Added code to the Linux-specific portion of the generic DRM layer to not initialize AGP infrastructure if the card is not AGP (this matches what already existed in BSD). Fix up i810/i830 and i915 drivers to always return AGP as they don't always report the capability. Fix the MGA to not report AGP for a card that has an AGP chip behind a PCI bridge.
