MSI interrupts appear to not work for nv46 based cards. Change the mc subdev oclass for these cards from nv44 to nv4c, the nv4c mc code is identical to the nv44 mc code except that it does not use msi (it does not define a msi_rearm callback).

The inst variable (and thus engctx) will not be properly populated for pre-NV44 cards. The dma setter method didn't need it anyways, so call it directly instead of the nv_call indirection.

The NV4A (aka NV44A) is an oddity in the family. It only comes in AGP and PCI varieties, rather than a core PCIE chip with a bridge for AGP/PCI as necessary. As a result, it appears that the MMU is also non-functional. For AGP cards, the vast majority of the NV4A lineup, this worked out since we force AGP cards to us...

Hello, I'd like to recommend backporting this commit: commit 0a363e85cdafbceeee6a49b91c604d0d4d070dc7 Author: Hans de Goede <hdegoede at redhat.com> Date: Thu Jul 23 17:20:12 2015 +0200 drm/nouveau/nv46: Change mc subdev oclass from nv44 to nv4c This disables MSI by default on G72 (NV46) devices where it's apparently a bit buggy. We have a later patch which turns MSI back on with a quirk, but it isn't extremely necessary for these devices, and disabling (or, rather, not enabling) MSI is a pretty safe thing to do. The patc...

Is there a way to use "Nouveau" (open source Nvidia) driver in CentOS 5 ? "nv" seems to support only the lowest resolutions thru the dvi output (NV44 chip), and I don't like the idea of installing propiertary Nvidia drivers. This way I came to Nouveau. I had a look at some Fedora rpms, but they needed something CentOS obviously doesn't have: # rpm -ivh xorg-x11-drv-nouveau-2.1.6-1.fc8.x86_64.rpm kernel-drm-nouveau = 10 is needed by xor...
