====== Nvidia Mellanox Technologies MT27520 Family [ConnectX-3 Pro] ======

Works for debian 11 on proxmox 7.3 and also Truenas.


For proxmox:

The driver is already embedded. Just load apropriate modules

''%%modprobe mlx4_ib (or mlx4_en)%%''

''%%modprobe ib_ipoib%%''

then install mstflint

''%%apt-get install mstflint%%''

then

mstflint -d xx:yy.z q

You should see your configuration.

Then enable your link by

ip link set ibsxxxx up

Sometimes after flashing of mcx314 to mcx354 for instance you need to change guids for infiniband

mstflint -d ca:00.0 --guids 0002c9b300067400 0002c9b300067401 0002c9b300067402 0002c9b300067403 sg

then reload pci-e by

echo "1" > /sys/bus/pci/devices/0000\:xx\:yy.z/remove

echo "1" > /sys/bus/pci/rescan

you should in principle see your cards by ip a and in the network manager

First need to disable nouveau driver:

Create a file in terminal as root or add sudo
<code>nano /etc/modprobe.d/blacklist-nouveau.conf</code>

With the following contents:

<code>blacklist nouveau
options nouveau modeset=0</code>

Or in terminal for script:
<code>bash -c "echo blacklist nouveau > /etc/modprobe.d/blacklist-nvidia-nouveau.conf"</code>
<code>bash -c "echo options nouveau modeset=0 >> /etc/modprobe.d/blacklist-nvidia-nouveau.conf"</code>

Regenerate the kernel initramfs:

<code>update-initramfs -u</code>

Reboot system.

if rebooted in terminal, good. If no, then enter terminal with <code>ctrl+Alt+F2</code>

====== Here can start when update driver ======

Download Nvidia driver for Your card:
https://www.nvidia.com/Download/index.aspx

Enter terminal <code>Ctrl+Alt+F2</code>

then stop X server:
<code>init 3</code>

Then need to make downloaded driver.run file executable:
<code>chmod 777 ~/NVIDIA-Linux-x86_64-470.57.02.run</code>

Then just run ~/NVIDIA-Linux-x86_64-470.57.02.run file and follow on screen questions.

Yes to all.


If success, restart system and enjoy!

P.S. If can.t find nvidia control panel, run nvidia-settings as root in terminal.
