Summary: i810 DRM module does not initialize
Product: DRI
Version: DRI CVS
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P2
Component: DRM modules
AssignedTo: dri-devel@lists.sourceforge.net
ReportedBy: [EMAIL PROTECTED]
The i810 module from the 2005-05-30 DRI CVS snapshot does not initialise
properly with these error messages:
[drm] Initialized drm 1.0.0 20040925
[drm:fill_in_dev] *ERROR* Cannot initialize the agpgart module.
DRM: Fill_in_dev failed.
However, the intel-agp module was loaded previously and initialized
successfully:
agpgart: Detected an Intel i810 DC100 Chipset.
agpgart: Maximum main memory to use for agp memory: 148M
agpgart: detected 4MB dedicated video ram.
agpgart: AGP aperture is 32M @ 0xe6000000
Looks like the problem is that the drm_device_is_agp() test fails, therefore DRM
does not even attempt to initialize AGP. The builtin i810 graphics device does
not advertize the AGP capability:
