[PATCH] support i945G as i915G in intel-agp.c none

Description wingc 2005-05-17 18:09:14 UTC 
Description of problem:

The intel-agp driver does not support the i945G host bridge found in recent
Intel-based x86_64 capable PCs. The existing i915G code in the RHEL4 kernel
seems capable of driving the i945G if the appropriate PCI IDs are added.

Version-Release number of selected component (if applicable):

Tested on most recent RHEL4 beta kernel (2.6.9-6.37.EL)

How reproducible:

Always

Steps to Reproduce:
1. try to get agpgart working on a i945G based machine
  
Actual results:

intel-agp driver does not recognize the i945G.

Expected results:

Additional info:


Attached is a patch against the most recent RHEL4 beta sources (2.6.9-6.37.EL)
which adds the i945G PCI IDs and just uses the existing i915G code in
intel-agp.c. Using this patch, I built the intel-agp driver as a standalone
module for x86_64. I can confirm that with this patch, OpenGL is working
properly on my hardware (pre-production Dell GX620, x86_64, with onboard i945G
graphics)

Taken as a series, when these are all resolved it will be possible to get
working OpenGL acceleration in RHEL4 for the i945G integrated graphics chipset
on x86_64.
