>Description:
- add support for the Intel® E7505 Chipset to agp(4)
I have this chipset in my workstation. Without this change, i had no
agp0 device and therefore the drm_attach for my Matrox G550 AGP card
failed.
After changing src/sys/pci/agp_intel.c i get an agp0 device and the
drm_attach is successful. I finally get /dev/agpgart and /dev/dri/card0
whithout any errors.
>How-To-Repeat:
>Fix:
- apply the attached patch
Attention:
The patch is for current as of today but all my testing was done on
RELENG_6. So i think this is a really good MFC candidate.
