GEM shrinker and vm.overcommit_memory=2

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



In fairly recent past, it was not possible to run desktop systems using
vm.overcommit_memory=2 if they used Intel graphics because without the
OOM killer, the shrinker would never run.  Instead, regular memory
allocations would fail eventually.

In addition, the i915 Mesa driver assumed malloc would never fail.  So
eventually, the whole desktop infrastructure would crash with a NULL
pointer dereference somewhere in Mesa.

Is running with vm.overcommit_memory=2 a supported configuration?  I
expect that vm.overcommit_memory=2 mode could be an interesting
operating mode for OpenCL workloads.

Thanks,
Florian
