r350 drm

Wed May 4 21:48:42 PDT 2005

I decided to play around with all the new DRM/DRI/XORG/ETC stuff.  I 
looked over at the r300.sourceforge.net site for some info, added my 
All-In-Wonder 9800 Pro to the PCI IDs (see attached drm.diff), and then 
kldloaded radeon.  Looks like it worked successfully:

kernel: drm0: <ATI Radeon NH R350 9800 Pro> port 0x7800-0x78ff mem 
0xd0000000-0xd7ffffff,0xefcf0000-0xefcfffff irq 16 at device 0.0 on pci1
kernel: info: [drm] AGP at 0xe0000000 128MB
kernel: info: [drm] Initialized radeon 1.16.0 20050311 on minor 0
kernel: info: [drm] Loading R300 Microcode

With the xorg-server-snapshot and dri-devel I seem to have even enabled 
direct rendering (see Xorg log output in attached drm.txt), although 
render acceleration is disabled.

My question is this:
Does direct rendering without render acceleration gain me anything?

Corollary:
Does my patch actually do anything useful?

It's awesome to see parts of the All-In-Wonder like the RageTheater 200 
chip being detected.  I can't wait to not have to reboot into Windows to 
watch TV...

(WW) RADEON(0): Enabling DRM support

	*** Direct rendering support is highly experimental for Radeon 9500
	*** and newer cards. In fact, the only thing you could probably use
	***  it for is better 2d acceleration. The 3d mesa driver is not  
	*** provided in this tree. A very experimental (and incomplete)
	*** version is available from http://r300.sourceforge.net
