Can't you also use info.max_alloc_size here?
I can do *max_global_size = max_alloc_size; Does that sound good?
Even if max_alloc_size can be 256 MB?

How about
*max_global_size = MIN2(4 * max_mem_alloc_size,
rscreen->info.max_alloc_size);
Would that work? That avoids calculating the same value in two distinct
places, since rscreen->info.max_alloc_size =
MAX2(rscreen->info.gart_size, rscreen->info.vram_size) for both radeon
and amdgpu.

Vedran
