Make sure we pick the right GART when disabling AGP.
This patch doesn't apply to 2.6.31. It's not completely trivial to fix
either - these declarations
+ void r100_pci_gart_tlb_flush(struct radeon_device *rdev);
+ int r100_pci_gart_enable(struct radeon_device *rdev);
+ void r100_pci_gart_disable(struct radeon_device *rdev);
+ int r100_pci_gart_set_page(struct radeon_device *rdev, int i, uint64_t addr);
would naturally lie in radeon_asic.h but we can't do that because some
stupidhead went and put this:
static struct radeon_asic r100_asic = {
into a .h file, making that header file unusable for the things which
header files are used for.
So please have another go.
If you believe that the the patch is suitable for backporting into 2.6.31.x
then please
- cc sta...@kernel.org on the patch
- add a `Cc: sta...@kernel.org' to the changelog
- ensure that the changelog text explains to the -stable maintainers why
this patch should be backported.
Thanks.

Just to clarify which gart block is on what r3xx/r4xx asic; If the
card is chip family CHIP_R300, CHIP_R350, CHIP_RV350, or CHIP_R420, it
uses the AIC PCI gart. If the chip family is CHIP_RV380, CHIP_R423,
or CHIP_RV410, then it uses PCIE gart.
