Replace the integer overflow with a scaling issue instead! commit e7faf33ec791b78b2bf1ebb81be228364c3439c4 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Thu Feb 4 22:18:33 2016 +0000 igt/gem_ctx_thrash: Rewrite to avoid extraneous allocations The goal of the test is to exercise what happens when we fill the Global GTT with the contexts. To that end, we only need to allocate 2/4GiB of context objects, and can forgo filling each context with buffers.
