  -Dvulkan-layers=device-select"

Type or paste the following cmd in the linux terminal program (the compiling/installation process may take some time):

sudo ninja -C build64 install


If you need to rebuild the 64 bit mesa driver, just delete the build64 folder which is inside the mesa folder and repaste the build/install cmdlines.

Example: sudo rm -rf build64



32 bit mesa driver:

Type or paste the following cmd(s) one at a time in the linux terminal program:

mkdir -p ~/.local/share/meson/cross

sudo nano ~/.local/share/meson/cross/gcc-i686

Paste the below into the opened text file:

# gcc-i686
[binaries]
c = '/usr/bin/gcc'
cpp = '/usr/bin/g++'
ar = '/usr/bin/gcc-ar'
strip = '/usr/bin/strip'
pkg-config = '/usr/bin/i686-linux-gnu-pkg-config'
llvm-config = '/usr/bin/llvm-config'

[built-in options]
c_args = ['-m32']
c_link_args = ['-m32']
cpp_args = ['-m32']
cpp_link_args = ['-m32']

[host_machine]
system = 'linux'
cpu_family = 'x86'
cpu = 'i686'
endian = 'little'



Press ctrl+x, press the "y" key and press enter to save.

Note: At this time, llvm doesn't build/install for 32 bit. Don't actually know if it is necessary at all.

Type or paste the following cmd(s) one at a time in the linux terminal program and Press the "y" key if prompted at any time. 
(The reason why one has to enter so many commands is because I don't know if mesa has a 32 bit build dependency package for debian, welcome to find out if they do which would greatly simplify the process)

Type or paste the following cmd in the linux terminal program (the compiling/installation process may take some time):

sudo ninja -C build32 install

If you need to rebuild the 32 bit mesa driver, just delete the build32 folder which is inside the mesa folder and repaste the build/install cmdlines.

Example: sudo rm -rf build32

Type or paste the following cmd(s) into the linux terminal program:

sudo apt-get install vulkan-tools



You can then list your installed vulkan drivers with the cmd below:

ls /usr/share/vulkan/icd.d/


You should see "virtio_icd.x86_64.json"and 

"virtio_icd.i686.json" 



To test drivers:

VK_ICD_FILENAMES=/usr/share/vulkan/icd.d/virtio_icd.i686.json:/usr/share/vulkan/icd.d/virtio_icd.x86_64.json vkcube


For permanent 32/64 bit driver(no need to enter the above command with every program you want to use vulkan driver).

Type/paste the following cmd:

sudo nano /etc/environment

In the text file paste the below:

VK_ICD_FILENAMES=/usr/share/vulkan/icd.d/virtio_icd.i686.json:/usr/share/vulkan/icd.d/virtio_icd.x86_64.json

Press ctrl+x, press the "y" key and press enter to save.

Try typing "vulkaninfo" without quotes to get vulkan driver information.

The command "vulkaninfo | grep driverName" should return something like this:

driverName      = venus
        driverName                                           = venus


If you enter the below "vkcube" without quotes in the linux terminal program, you should see something like below, and also a spinning cube:

usulyre@penguin:~$ vkcube

Selected GPU 0: Virtio-GPU Venus (AMD RADV STONEY), type: 1


On an intel based chromebook:

usulyre@penguin:~$ vkcube

Selected GPU 0: Virtio-GPU Venus (Intel(R) UHD Graphics 600 (GLK 2)), type: 1


If vkcube doesn't work, either restart the chromebook and go to crosh enter your vmc start cmdline and try vkcube again in terminal or go to crosh and type "exit" and then after that in crosh type "vmc stop termina" then you enter your vmc start cmdline and try vkcube again in termina.



Useful/optional flags in "chrome://flags:"

chrome://flags/#exo-ordinal-motion

Some notes: 

There may be bugs, errors, etc. You can update the driver by deleting the mesa folder and use git clone to redownload the latest version of the driver,then go to the mesa folder and build/install the driver. Or go to the mesa folder and type without quotes "git pull origin" which will pull the newest updates to mesa to your system. You can then run the install cmds which should incorporate the newest updates. No need to redownload the dependencies, etc.

For an FPS counter vulkan apps only: add to /etc/environment this "VK_INSTANCE_LAYERS=VK_LAYER_MESA_overlay" without quotes.


For Lutris:

After installing Lutris you need to go to the mesa folder and run the install cmds again:

cd mesa

sudo ninja -C build64 install

sudo ninja -C build32 install

How did you get llvm:i386 and llvm-dev:i386 to install? For me it removes python3-mako, etc. and I can't get past the configuration part.

I think my soultion for my problem is wrong, but beacuse I din't have python3 install from the apt source so the problem is not occur on my machine, but you are right the conflict is true. I didn't create a new crostini container, maybe this is the reason why it's different for me.

I had been skipping llvm 32 bit and the driver does compile/install, but I don't know if not compiling/installing has any effect.

Yeah, I agree with you, after fail to compile the 32bit driver, I run the vkcube and vulkaninfo, they show the expect output. I think my tested game is also able to run with the vulkan 64bit driver. So I don't think I need the 32bit driver, maybe some old 32bit game will need 32 bit driver.

Here's the corrected version of your text:

"Last time, due to dependency conflicts, I removed the llvm:i386 and llvm-dev:i386 packages. Afterward, I assumed everything would work as normal. However, today when I attempted to launch Steam, it displayed an error stating it was unable to locate the DRI driver. I then tried updating the Mesa repository and meson from the sid source, and recompiled the 64-bit driver, but Steam still wouldn't launch. Subsequently, I attempted to compile the 32-bit driver, only to encounter the same problem: /usr/bin/ld: cannot find -lLLVM-14: No such file or directory.

To address this properly, I decided to change llvm-config to llvm-config-15 in the file ~/.local/share/meson/cross/gcc-i686. The version of llvm-config should match the LLVM version used when compiling the 64-bit driver. This resolved the compilation issue for the 32-bit driver. After installing the 32-bit driver, Steam ran perfectly.

It seems the complication arises from having two versions of LLVM on my system. While the default version is llvm-14, the 64-bit driver compilation seems to be using llvm-15, though I'm unsure why. Perhaps examining the meson.build file under the Mesa folder could shed some light on this issue.

Additionally, with meson version 1.4.0, it specifies that 'pkgconfig' should be 'pkg-config' in the file '~/.local/share/meson/cross/gcc-i686'."

Hope this will help others, have a nice day.

Hi, regarding llvm-config, I'm not able to install llvm-16:i386 if llvm-16 is installed, it keeps saying that it wants to remove llvm-16 and some python packages.

I tried to use llvm-config-16 in crossfile but compiling error happens when almost finished. I believe this has something to do with not having llvm-16:i386 installed.

For pkgconfig changed to pkg-config, I can change that.

The default llvm version is llvm-14 in my system. The 64 bit driver compiles perfectly but I notice ninja using llvm-15 instead of using default llvm-14 when compile the 64 bit driver.In the cross compile file the llvm-config is llvm-config-14. If I use llvm-config(llvm-config-14), compile 32 bit driver will failed when almost finished.

First time I installed the llvm-14:i386 but as you said, it introduced package conflicts.So I think solve the 32 bit drive compile fail by installing the llvm:i386 pakckage is wrong. I think compile the 32 bit driver does not need llvm:i386.

So this time I change llvm-config to llvm-config-15, make sure using the same llvm version when complie 64 bit driver and 32 bit driver. After that, both compiles success.Due to my limited understanding of cross compile, I am not sure this solution is right, maybe this solution works only in my system.
