Sure I will add details about how to build the code, I use basically meson
and ninja commands,
My build directory located in mesa source here is my meson command to
configure (I know this does more work than require please add more options
if you find useful):
meson -Dbuildtype=debug -Dprefix=/home/vivek/install
-Dvulkan-drivers=libresoc ..

and then

ninja

ninja install.

I also have script to set few environment variables like

export
VK_ICD_FILENAMES=/home/vivek/install/share/vulkan/icd.d/libresoc_icd.x86_64.json
export VK_LOADER_DEBUG=warn
export LIBRESOC_TRACE=1

I am doing some experiments with extension and entrypoint generation code,
so those files will change.
I would request not to waste time on current code I have pushed.

To test the code I am sing simple tests built by
https://github.com/GameTechDev/IntroductionToVulkan

I am also using debug build for vulkan loader if any one interested in that
please look at
https://github.com/KhronosGroup/Vulkan-Loader/blob/master/BUILD.md

Thanks,
Vivek
