After I use 3.4 rc6 kernel which contains IVB_GT2_IG, intel agp and VGA are recognized now.
The "lspci" command now shows that PCI 00:00.0 uses Kernel driver agpgart-intel and PCI 00:02.0 uses i915 now.
before I use the 3.4 kernel, there was nothing about the driver info.
The /dev/dri folder is created now, containing card0 and controlD64.
But the /var/log/Xorg.0.log still complains about "No devices detected", after loading
/usr/lib/xorg/modules/drivers/intel_drv.so .
And there is also an error in the "dmesg" output:
[drm:intel_dsm_platform_mux_info] *ERROR* MUX INFO call failed
I don't know whether it has anything to do with the Xorg error.
Thanks

I try to use VAAPI,an error comes out ""Xfree86-DRI "missing on display ":0".libva:va_getDriverName() returns -1"when using ivybridge CPU(xeon E3-1285,3.6GHz ) ,but sandybridge CPU works well.
I check the Xorg.0.log,find "failed to load module "intel_drv.so ".
dmesg: [ 3.156733] [drm:i915_init] *ERROR* drm/i915 can't work without intel_agp module!
I printk my device in 3.3.4 kernel Intel_agp source code,my device is PCI_DEVICE_ID_INTEL_IVYBRIDGE_S_HB 158,
It appears in intel_agp.h
#define PCI_DEVICE_ID_INTEL_IVYBRIDGE_S_HB 0x0158 /* Server */
but in intel-gtt.c
intel_gtt_chipsets[]=
{
......
{ PCI_DEVICE_ID_INTEL_IVYBRIDGE_GT1_IG,
"Ivybridge", &sandybridge_gtt_driver },
{ PCI_DEVICE_ID_INTEL_IVYBRIDGE_GT2_IG,
"Ivybridge", &sandybridge_gtt_driver },
{ PCI_DEVICE_ID_INTEL_IVYBRIDGE_M_GT1_IG,
"Ivybridge", &sandybridge_gtt_driver },
{ PCI_DEVICE_ID_INTEL_IVYBRIDGE_M_GT2_IG,
"Ivybridge", &sandybridge_gtt_driver },
{ PCI_DEVICE_ID_INTEL_IVYBRIDGE_S_GT1_IG,
"Ivybridge", &sandybridge_gtt_driver },
......
}
There isn't a PCI_DEVICE_ID_INTEL_IVYBRIDGE_S_HB .
It is in included in intel_agp.c.
But I suspect that the problem is that you are missing the IVB GT2 Server variant support, which we added this April.
Could you post your "lspci -n | grep 00:02" output please?
