Hi,

Since commit 8a4d7f34d9c0182c466518c6f413d9a039db402d, when I try to insert
nouveau.ko, it failed with unknown symbol, and dmesg say :

[drm] Initialized drm 1.1.0 20060810
nouveau: Unknown symbol pci_get_bus_and_slot

I get a warning at this place during the compilation

/home/jules/nouveau/drm/linux-core/nouveau_mem.o
/home/jules/nouveau/drm/linux-core/nouveau_mem.c: In function
'nouveau_mem_fb_amount_igp':
/home/jules/nouveau/drm/linux-core/nouveau_mem.c:230: warning: implicit
declaration of function 'pci_get_bus_and_slot'
/home/jules/nouveau/drm/linux-core/nouveau_mem.c:230: warning: assignment makes
pointer from integer without a cast


commenting out the body of the function nouveau_mem_fb_amount_igp, I can
compile without warning and insert the module (and Nouveau works).


I'm running linux mandriva 2007.1 with kernel 2.6.17, gcc 4.1.2, x86_64.

------- Comment #1 from pmandin at caramail.com  2007-08-20 09:25 PST -------
A #ifdef check for both Linux kernel (in case of Bsd or other OS) and Linux
kernel version (pci_get_bus_and_slot() function needs 2.6.19) has been added.
It means detection of IGP memory will fail if not Linux>=2.6.19, but at least
the module is loadable again.
