From 068143d38804825d59d951a192cfadd2e22f457d Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Mon, 5 Oct 2009 09:58:02 +1000 Subject: drm/fb: add setcmap and fix 8-bit support. This adds support for the setcmap api and fixes the 8bpp support at least on radeon hardware. It adds a new load_lut hook which can be called once the color map is setup.

The previous patches had some unwanted side effects, I've fixed the lack of 32bpp working, and fixed up 16bpp so it should also work. this also adds the interface to allow the driver to set a preferred console depth so for example low memory rn50 can set it to 8bpp. It also catches 24bpp on cards that can't do it and forces 32bpp. Tested on r100/r600/i945.
