[Bug] libclc-amdgcn missing files for current AMD Custom GPU 0405 APU

[MrSandman]

Bug Description

I'm finding that the libclc support for current AMD APU is missing, at least for AMD Custom GPU 0405 APU. when running something like `clinfo`, you get the following:

=== CL_PROGRAM_BUILD_LOG ===
fatal error: cannot open file '/usr/share/clc/gfx1030-amdgcn-mesa-mesa3d.bc': No such file or directory
Preferred work group size multiple (kernel) <getWGsizes:1504: create kernel : error -46>


Not gfx1030-amdgcn-mesa-mesa3d.bc file in libclc-13.0.0-1-any.pkg.tar.zst package and/or /usr/share/clc path

Still not working opencl on steamdeck.

Steam support is not responding.

"Steam support is not responding."

What are you expecting them to say, they would need to wait for SteamOS to be updated with it if you're not willing to install it yourself

And thats still going to require a SteamOS update to resolve, not sure which part of mine you didn't read, support can't help you, it will be down to the team building SteamOS

A month ago, I opened a support ticket about this problem in the graphics driver. Support closed the ticket and told me to open the ticket in this forum, since it was a bug.

I don't care how long it takes. What I am denouncing is that they do not deign to respond to a bug that directly affects the announced capabilities, which they are not complying with and for which the owners have paid.

I hope this clears your doubts.

Right but what advertised capability is this actually affecting, because one would assume its missing from all decks, yet all of them seem to be running fine with all advertised features, what exactly is this breaking that was advertised?

An OpenCL game physics compatibility. Mesa driver basic feature.

AFAIK, this libclc is part of llvm, and currently (october 2023) i guess it is still under development, because noone ships this gfx1030-amdgcn :-(

There are open requests on github/llvm for 1010 stuff...

If find this issue because this lib is lacking for mesa openCL for RX6800XT too

If you need openCL :

• One possibility is compile it from source, that is compile llvm/libclc/ and i guess the gfx1030-amdgcn-* will not work (or it would have been included in a linux distro)
  
• Use Rocm from AMD site. It works on RX6800XT, maybe it will on steamdeck too.

But if you wreak havoc in your nice steam deck it is not my fault :-)
