From 8e1004580e0c862cb6bbe2ff8e496f846c54052f Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Kristian=20H=C3=B8gsberg?= Date: Mon, 5 Jan 2009 16:10:05 -0500 Subject: drm: Drop unused and broken dri_library_name sysfs attribute. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The kernel shouldn't be in the business of telling user space which driver to load. The kernel defers mapping PCI IDs to module names to user space and we should do the same for DRI drivers. And in fact, that's how it does work today. Nothing uses the dri_library_name attribute, and the attribute is in fact broken. For intel devices, it falls back to the default behaviour of returning the kernel module name as the DRI driver name, which doesn't work for i965 devices. Nobody has ever hit this problem or filed a bug about this.
