![]() ![]() What’s interesting is the minimum swap chain image count is 3, max is 0 but vkGetSwapchainImagesKHR returns 5. Thought I’d show the information displayed from my game engine running Vulkan on Raspberry Pi. I know 64bit is not your priority, but maybe it helps to improve the driver.

Update 2 : Mike Hooper pointed more issues on gitlab Author infapi00 Posted on JNovemCategories Igalia, Mesa, Raspberry Pi, Vulkan Update : rpiMike on the comments, and some people privately, have pointed some errors on the post. But a list of some that we tested and seem to work: So in order to see a really familiar demo: $ cd build/binĪnd one slightly more complex: $./scenerenderingĪs mentioned, not all the demos works. ![]() Recently the fonts were moved there, so you would need to gather the assests always: $ cd. Update : When the post was originally written, some demos didn’t need to ask for extra assets. To make things easier to everybody, here another quick recipe of how to get them build: $ sudo apt-get install libassimp-dev So what Vulkan programs are working? For example several of the Sascha Willem Vulkan demos. This also means that you don’t need to use LD_PRELOAD, LD_LIBRARY_PATH or similar That envvar is used by the Vulkan loader (installed as one of the dependencies listed before) to know which library load. Now, the easiest way to ensure that a vulkan program founds the drivers is setting the following envvar: export VK_ICD_FILENAMES=/home/pi/local-install/share/vulkan/icd.d/broadcom_ The recipe is also building the OpenGL driver, just in case anyone want to compare, but if you are only interested on the vulkan driver, that is not mandatory. You could set a release build, or any other directory. This builds and install a debug version of v3dv on a local directory. Now v3dv is merged on Mesa upstream, so in order to clone the repository now you just need to do this: $ git clone $ meson -prefix /home/pi/local-install -libdir lib -Dplatforms=x11,drm -Dvulkan-drivers=broadcom -Ddri-drivers= -Dgallium-drivers=v3d,kmsro,vc4 -Dbuildtype=debug _build This is the simpler recipe to build v3dv: $ git clone mesa For those people, they were able to fix that doing this: $ sudo apt-get remove meson It seems that some people had problems if they have installed meson with apt-get on their system, as when building it would try the older meson version first. There is the option to build meson from the tarball (meson-0.52.0 here), but by far, the easier way to get a recent meson version is using pip3: $ pip3 install meson Mesa has just recently bumped up the version needed for meson, so Raspbian version is not enough. Most Raspian libraries are recent enough, but they have been updating some of then during the past months, so just in case, don’t forget to update: $ sudo apt-get updateĪdditionally, you woud need to install meson.

As it is really likely that some people would be interested on testing it, even if it is not complete at all, here you can find a quick guide to compile it, and get some demos running. Just today it has published a status update of the Vulkan effort for the Raspberry Pi 4, including that we are moving the development of the driver to an open repository. ![]()
