From 019d96cb55ade38a4b4a52bba0304e8cd681f30a Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Thu, 29 Sep 2011 16:20:42 +0100 Subject: drm: add some caps for userspace to discover more info for dumb KMS driver (v2) For the simple KMS driver case we need some more info about what the preferred depth and if a shadow framebuffer is preferred. I've only added this for intel/radeon which support the dumb ioctls so far. If you need something really fancy you should be writing a real X.org driver. v2: drop cursor information, just return an error from the cursor ioctls and we can make userspace fallback to sw cursor in that case, cursor info was getting too messy, best to start smaller.
