How to install on 64-bit

[Joseph-Azzam]

Hi,
I'm a bit stuck and would appreciate your help.
I don't have experience installing drivers for Linux, not sure if I'm missing something.
I followed the steps in Build.MD:

How to compile on a Raspberry Pi
Clone RPi VK Driver
git clone https://github.com/Yours3lf/rpi-vk-driver.git
cd rpi-vk-driver
mkdir build
cd build

Run CMake
cmake .. -DCMAKE_BUILD_TYPE=Release

Build project
cmake --build . --target all

I executed them successfully, except for "_cmake --build . --target all" had a couple of error compiling armv6.
I get stuck on run Install.sh
install.sh is missing the "librpi-vk-driver.so"
not sure if it's important but either way the driver does not install.

I am using Raspberi Pi OS Beta to run a AArch64 Vulkan app.
Thank you in advance

Hey,

the master branch is very much in development, it might not always build. I fixed it now, so please try again.
You need the cmake build step to finish successfully so you can install the driver SO file (librpi-vk-driver.so) to the right place.

cheers

For the release v1.0, use

git clone -b v1.0 https://github.com/Yours3lf/rpi-vk-driver.git

I am working on a raspberry pi 3b+, with raspberry pi OS 64bit Arch64 beta.
I downloaded the latest master and release v1 versions, and still encountered compile errors.
I commented in makelist.txt the armv6 architecture line, and uncommented armv8a.
I also added set(CMAKE_CXX_FLAGS "=fpermissive").
Compile required .so libraries that are included in the project but where skipped because they are incompatible, so I manually downloaded the equivalent one using apt-get "missing-library-name-dev".
I included math.h in a certain library that complained about using log2.
That fixed most of the errors, but the main error I could not fix was, which came up in multiple files:
error: cannot convert ‘VkImageView’ {aka ‘VkImageView_T*’} to ‘VkImage’ {aka ‘VkImage_T*’} in assignment
imageMemoryBarrier.image = depthImageView;

Am I missing something?

[Yours3lf]

It compiles fine on the latest release of raspberry pi os, have you tried that?

[Joseph-Azzam]

I need it to work on the 64-bit raspberry OS to make use of the AArch64 support.

[Yours3lf]

Reopening for testing on 64bit Raspberry Pi OS. Since it's still beta I can't guarantee it's going to work.
Just use the 32 bit version for now.

[Yours3lf]

so to build on arm64

1. set arch to armv8-a in CMakeLists.txt
2. add compile option -fpermissive in CMakeLists.txt
3. install libdrm-dev, libx11-dev, libxrandr-dev, libmtdev-dev, libevdev-dev, libudev-dev, libinput-dev
4. build and install https://github.com/KhronosGroup/Vulkan-Headers
5. set VULKAN_HEADERS_INSTALL_DIR=/usr/local
6. build and install Vulkan-Loader with -DBUILD_WSI_WAYLAND_SUPPORT=OFF
7. change depthImageView to depthImage when it complains (or just don't build that test)

[Yours3lf]

Then if you test blending for example you get:
Thread 1 "blending" received signal SIGSEGV, Segmentation fault.

which probably happens because I never tested the driver on 64bit, so you'll run into issues with that (pointers being 8 bytes long etc.)

[Joseph-Azzam]

Thank you, I will try those changes over the weekend

[paulwratt]

can someone change the topic title to say "How to build for 64bit?" (easier to find later)

thanx for this info and the whole project @Yours3lf - OpenArena just does not cut it

[Joseph-Azzam]

Hi Yours3lf, Thank you a ton for taking the time to look into this, it's appreciated.
I can confirm the installation worked by following these steps.

[paulwratt]

Unless these 64bit build instructions are posted in a doc within the project, can I ask this issue stays open as an "instructional" issue, which should come up in searches

[vanfanel]

@Yours3lf:
In the first place, congratulations for this massive archivement: Vulkan on Pi3 is something I couldn't even imagine!! :-O

I am also trying to build for Raspbian OS 64bit, instead of Raspbian OS.
I found the instructions in this thread by pure chance, so I think @paulwratt is right: This thread should be re-opened or the 64bit building instructions should be added to README.md or BUILD.md
