Bug ID: 94525 Summary: OpenCL memory allocation is limited to 1GB Product: Mesa Version: git Hardware: x86-64 (AMD64) OS: Linux (All) Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/radeonsi Assignee: dri-devel@lists.freedesktop.org Reporter: b.bellec@gmail.com QA Contact: dri-devel@lists.freedesktop.org
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".
