o you have the ability to build libclc from source from a checkout of
the LLVM repository?
The repository is here: https://github.com/llvm/llvm-project.git
You'd only need to build/install the libclc/ sub-project to test any
prospective patches (see attached), not the full LLVM project.
I've attached a basic patch that adds some AMDGPU subtargets that were
missing along with the LLVM version they were added in.
In your case, as long as you are building libclc against LLVM 9.0 or
higher, it should automatically add in support for your GFX1010 chip
when building. Hopefully that'll be enough to get you through clinfo.
Not sure if anything more complicated will be required for your chip,
but this should get us started.
If you've got cmake/make/llvm/clang installed, clone the LLVM
repository I listed above, then:
cd build && cmake ../
make -j && sudo make install
You could probably skip the `make install` part and copy the one file
you're interested in manually, but I'll leave that to you to decide
how much custom stuff you want installed on your system :)
Let me know if this works/doesn't-work.
