There is a potential hazard here for parallel compilation and to a lesser
extent testing. (I have just learned that) kfd imposes a process limit which is
low enough that we may see hsa_init fail under multiple processes.
@jdoerfert you talked me out of embedding a map from pci.ids to architecture as
we'd have to keep it up to date, and it can diverge from how the runtime
libraries identify the hardware. I'm starting to think that's the lesser of two
evils. Would probably look something like
id = cat-somewhere-in-/sys
switch(id) {
default:
return nullptr;
case 0x67C0:
case 0x67C1:
case 0x67C2:
return "gfx803";
... // ~ 100 lines on this theme, picks up new entries when new hardware is
released
};
