Please consider importing jemalloc sources into mesa as a 'last' resort". On the steam front... I haven't really tested it but it should* be fine, since the glibc symbols are weak explcitly for the purpose or using custom allocator.
Above opting for either would be great to check with the example cases/programs that others have mentioned. Thanks Emil _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/mesa-dev
