I have a workstation with a [Radeon X600 (PCIE)] card. The X display has
been garbled since these DRM updates went in in January, and remains
garbled with 7.1-STABLE as of yesterday. As a work-around, I'm running
the up-to-date 7.1-STABLE system (both world and ports) with a
7.1-RELEASE-p2 kernel. The display is fine with the old kernel and X
works great; I even see dramatically improved performance with the new
Xorg and EXA acceleration. Your work is much appreciated.
But the garbled display with the recent DRM still plagues me.
Here's how pciconf identifies the card:
vgapci0@pci0:1:0:0: class=0x030000 card=0x06021002 chip=0x5b621002 rev=0x00 hdr=0x00

device = 'RV380 RADEON X600 Series 265MB'
class = display
subclass = VGA

device = 'Radeon X600 Series - Secondary'
class = display

Difference between the Xorg logs when it's working and when it's not:

-(WW) RADEON(0): Failed to determine num pipes from DRM, falling back to manual look-up!
I tried setting hw.dri.0.debug=1. That produced a lot of output, but
nothing that looked like an error or warning. Do you have any idea what
might be causing this, or how to troubleshoot further?
