pci_find_class obsolete

pci_find_class obsolete

[Jan Engelhardt]

Hello list,


after switching to 2.6.11-rc5-bk2 (from 2.6.9-rc2), I found that the nvidia 
module (1.0-4996, old, I know) does not compile anymore, because it
requires pci_find_class():

nv.c:
static int
nvos_probe_devices(void)
{
    ...
    struct pci_dev *dev;
    ...
    dev = pci_find_class(PCI_CLASS_DISPLAY_VGA << 8, dev);
    ...
}

What function would I need to use, now that pci_find_class is gone?

Hi!
you have to use pci_get_class (). But have a look at the patches for 
6111 on my webiste:

I use 4996 because it uses four times less kernel memory than 6111. (And on 
top, 6111 does not give me any performance improvements over 4996.)

What's the patch doing?

I do not use AGPGART/DRI - no performance plus either.
