The module parameter "msi=1" will enable it. There's a kernel bug which will cause this to fail if the module (or the NVIDIA binary driver) has ever been loaded before loading nouveau with MSI enabled. As such, this is only safe to enable if you have nouveau load on boot, and don't wish to ever reload it. The workaround is to "echo 0 > /sys/bus/pci/devices//enable" until the enable count reads 0. Then you should be able to load nouveau with MSI enabled. Signed-off-by: Ben Skeggs --- Reading git-diff-tree failed
