| Summary | [r600g] Memory leak desktop usage RV770 (HD4850) with 10.1.2 (related to not using LLVM anymore) |
| Severity | major |
| Classification | Unclassified |
| OS | Linux (All) |
| Reporter | vallesroc@gmail.com |
| Hardware | x86-64 (AMD64) |
| Status | NEW |
| Version | 10.1 |
| Component | Drivers/Gallium/r600 |
| Product | Mesa |
A long time ago (months? over a year?), I used to have this issue where mesa would cause the system to leak memory over time by just idling or browsing the web (kde, firefox) and at some point (just hours) it'd be bad enough (on 8GB RAM) that over 4GB swap would be used and system would be really slow because of that. Sorting processes by ram usage (on eg: top) would show no culprits; the memory was being leaked kernelside. Not even restarting X would fix the problem: A reboot was always necessary. The issue disappeared once I started building mesa with LLVM support... until now. 10.1.2 disables LLVM for RV770, which among other things fixes games such as DOTA2, but the problem is suddenly back, making me pretty sure it's linked to not using LLVM's shader compiler (or same thing, has to do with how shaders are compiled without LLVM).
