I wanted to try "ethminer" (the OpenCL Ethereum miner) on Mesa.
I installed Ubuntu 15.10 (x86-64), the "ethminer" client, and the Oibaf PPA Mesa packages.
The OpenCL's Mesa detects only 1GB on my Radeon R9 390 8GB.
So I can't even start "ethminer" since it currently requires 1.4 GB.
Moreover, the two others R9 Nano plugged in the computer are not even detected by "ethminer" nor "clinfo".
Should have been fixed by:

gallium/radeon: add and use radeon_info::max_alloc_size (v2)
v2: - squashed the patches
- use INT_MAX
- clamp max_const_buffer_size
- check the DRM version in radeon
