no direct rendering with via (s3) unichrome and XFree86 4.3.0.1
I can't seem to get direct rendering working. Here is my system info:
Linux 2.6.17.1
Debian 3.1r2.
XFree86 4.3.0.1
Relevant PCI info:
0000:01:00.0 VGA compatible controller: VIA Technologies, Inc.: Unknown
device 3108 (rev 01) (prog-if 00 [VGA])
Subsystem: Elitegroup Computer Systems: Unknown device 1828
Flags: bus master, 66MHz, medium devsel, latency 32, IRQ 10
Memory at e8000000 (32-bit, prefetchable) [size=64M]
Memory at ec000000 (32-bit, non-prefetchable) [size=16M]
Expansion ROM at <unassigned> [disabled] [size=64K]
Capabilities: <available only to root>
The file pci.ids says that device 3108 is an S3 Unichrome Pro VGA
Adapter. I think the 'via' module supports this.
This is what I did to try to get DRM working on my system:
** modprobe via
** Edit /etc/X11/XF86Config-4 and change this:
Section "Device"
Identifier "Generic Video Card"
Driver "vesa"
EndSection
to this:
Section "Device"
Identifier "Generic Video Card"
Driver "via"
EndSection
When I did the "modprobe via," dmesg said this:
[drm] Initialized drm 1.0.1 20051102
ACPI: PCI Interrupt 0000:01:00.0[A] -> Link [LNKA] -> GSI 10 (level, low) -> IRQ 10
[drm] Initialized via 2.7.4 20051116 on minor 0
And lsmod shows that drm and via are loaded.
But when I try to start X, it aborts with the message "(EE) no devices
detected."
How do I get my hardware to do DRI?
