Hi,

Ran some tests on 340, I'll do 304 tomorrow or during the weekend.

I've tested 3.2 on amd64 and i386, and 3.16.0-0.bpo.4, 4.3.0-1, 4.4.0-1
on all architectures. 4.5 fails due to missing file as per other thread,
not our fault.

DKMS builds fine on amd64 and i386, but fails on ARM because the Xen
test fails, despite the patch and that ARCH is set to arm:

...
if ! /bin/sh /var/lib/dkms/nvidia-current/340.96/build/conftest.sh "
gcc-4.9" " gcc-4.9" arm ...

conftest.sh:

...
CC="$1"
HOSTCC="$2"
ARCH=$3
...
if [ "$ARCH" = "arm" ] ||
         ! test_configuration_option CONFIG_XEN ||
         test_configuration_option CONFIG_PARAVIRT; then
        XEN_PRESENT=0
fi

Also, the dkms.conf on arm has the UVM bits enabled:

BUILT_MODULE_NAME[1]="nvidia-uvm"
BUILT_MODULE_LOCATION[1]="uvm/"
...


The kernel-source builds on i386, but curiously not on amd64,
conftest.sh is failing.

I'll investigate further tomorrow or during the weekend.

Kind regards,
Luca Boccassi
