[PATCH v1 5/5] accel/tcg: better handle memory constrained systems

2020-07-17 Thread Alex Bennée
It turns out there are some 64 bit systems that have relatively low amounts of physical memory available to them (typically CI system). Even with swapping available a 1GB translation buffer that fills up can put the machine under increased memory pressure. Detect these low memory situations and
