A gentle guide on getting your Tenstorrent card running on Arch Linux (with the Metalium stack)

Recently I got a message from Tenstorrent's community manager for helping with improving the installation documents. To make it easier for everyone. While that is still in progress, I wanted to document how I got my Tenstorrent card running on Arch Linux (since Tenstorrent officially only supports Ubuntu).

Installing your card

Just plug it into a PCIe slot. Remember to conenct the blower fan. Else the processor gets really hot.

Getting the driver running

I have uploaded my PKGBUILD script to the AUR for the kernel mode driver. You can install it via your preferred AUR helper. For me, I run yay -S tt-kmd-git-dkms.

=> AUR - tt-kmd-git-dkms

After installing. You should see the DKMS module via the dkms status command.

❯ dkms status 
tt-kmd-git/1.28.r2.g696c047, 6.9.7-arch1-1, x86_64: installed

Now, REBOOT you machine. The kernel module should be loaded and you should find a device /dev/tenstorrent/0. (Yeah, there should be a way to load the module without rebooting but I haven't figured it out yet.)

❯ ls /dev/tenstorrent/0
/dev/tenstorrent/0

And now you should be able to find your card via the lspci command.

❯ lspci | grep -i tens
04:00.0 Processing accelerators: Tenstorrent Inc Grayskull

Congratulations! You have successfully installed the kerenl module for your Tenstorrent card.

Installing management tools (tt-smi and tt-flash) and updating the firmware

Now let's setup the enviroment. Let's install the dependencies and a virtual python enviroment. I am using micromamba instead of conda. You can use conda if you want. Just Mamba is MUCH faster then conda. You can safely skip the Python stuff if you intend on doing only C++ development.

Getting Micromamba and dependencies

Here is the official guide if you want to read more about it.

=> Micromamba Installation

"${SHELL}" <(curl -L micro.mamba.pm/install.sh)

Now install system level dependencies and the virtual enviroment.

sudo pacman -S gcc cmake ninja git python python-pip rust cargo git-lfs
micromamba create -n tt-metal
micromamba activate tt-metal
micromamba install pip python==3.10 numpy # needed to make all packages happy

Installing tt-smi and tt-flash

tt-smi is the fansy nvidia-smi for Tenstorrent cards. tt-flash is the tool to flash the firmware on the card. You'll need both of them to manage your card. The flashing tool is easier to install. Just run the following command.

pip install git+https://github.com/tenstorrent/tt-flash.git

To install the tt-smi tool, clone the repository and install it via pip.

git clone https://github.com/tenstorrent/tt-smi
cd tt-smi
pip install .

### Firmware update

With both tools installed, you can now update the firmware on your card. To do this, clone the `tt-firmware` repository and run the following command (NOTE: **Read the README before running the commands, it might have changed since I wrote this guide**).

git clone https://github.com/tenstorrent/tt-firmware

cd tt-firmware

tt-flash fw_pack-80.9.0.0.fwbundle

## Building the SDK from source

Now let's setup the SDK. Unfortunately, it is not ready to become a system package yet, so you have to build it manually. Before that, let's install the dependencies and a virtual python enviroment. I am using micromamba instead of conda. You can use conda if you want. Just Mamba is MUCH faster then conda. You can safely skip the Python stuff if you intend on doing only C++ development.

### Enabling hugepages

tt-metal needs huge pages to wrok. The simplest way is to use Tenstorrent's helper scripts. Run the command:

wget https://raw.githubusercontent.com/tenstorrent/tt-metal/main/infra/machine_setup/scripts/setup_hugepages.py

sudo -E python3 setup_hugepages.py first_pass

And reboot. You should see an additional 1GBs of memory used at idle. That's the huge pages. Also run `sudo -E python3 setup_hugepages.py check` to make sure everything is working. Alternatively, you can cat `/sys/kernel/mm/hugepages/hugepages-1048576kB/nr_hugepages` and the number should be greater than 0. _You will need one huge page per devivce you have._

### Building tt-metal

First let's install all the dependencides. You want to use python 3.10 as some dependencies are not compatible with 3.12 that Arch ships. And you MUST have the virtual enviroment activated when building the SDK. Else it links with the system's Python and you'll have to rebuild the entire SDK to fix it.

Clone the entire repository (this will take a while as it also pulls in an entire RISC-V GCC via LFS).

git clone https://github.com/tenstorrent/tt-metal.git --recurse-submodules

cd tt-metal

git submodule foreach 'git lfs fetch --all && git lfs pull'

Then we can build the SDK. I strongly recommend to _not_ use the included script as (as of writting this post) it forces use of libc++ which is not compatible with the rest of the system. Instead, use the following commands. The only reason they default to libc++ is to use all of C++20 in Ubuntu 20.04.

cd tt-metal

export ARCH_NAME=grayskull # Replace this with wormhole_b0 if you have a Wormhole card

export TT_METAL_HOME=$(pwd)

export PYTHONPATH=$(pwd)

mkdir build

cd build

cmake

cmake .. -DCMAKE_C_COMPILER=gcc -DCMAKE_CXX_COMPILER=g++ -DCMAKE_BUILD_TYPE=RelWithDebugInfo -DCMAKE_EXPORT_COMPILE_COMMANDS=ON

make -j8

Install the SDK (it just installs everything to the "build/bin" directory)

cd ..

cmake --build build --target install

Now with the SDK built. Use the built in script to create a virtual enviroment. This will create a venv in `./python_env`.

./create_venv.sh

To test if everything is working. Run the following commands.

python

import ttnn

device = ttnn.open_device(0)

             Device | INFO     | Opening user mode device driver

2024-07-07 08:56:43.047 | INFO | SiliconDriver - Detected 1 PCI device : [0]

              Metal | INFO     | Initializing device 0. Program cache is NOT enabled

              Metal | INFO     | AI CLK for device 0 is:   1000 MHz

And... you are done! Happy messing with the device and AI hacking!

### Activating the virtual enviroment

In the future, you can activate the virtual enviroment by running the following commands.

cd /path/to/tt-metal

export ARCH_NAME=grayskull # Replace this with wormhole_b0 if you have a Wormhole card

export TT_METAL_HOME=$(pwd)

export PYTHONPATH=$(pwd)

micromamba activate tt-metal

source python_env/bin/activate

Using the sensors command to view power and temperature

If you don't want to use tt-smi. The kernel driver exposes the power and temperature to the regular sensors command.
