Because dma32 zone is on node 0, use all system memory on node 0 will cause TTM eviction to free dma32 zone for other devices which only work with 32bit physical address. The TTM eviction and restore may take too long and cause queue timeout. Running on other NUMA nodes, the NUMA default memory policy is MPOL_PREFERRED, means TTM will get pages from local node first, and then get remaining pages from other nodes. Check /proc/buddyinfo can confirm this. Reset NUMA bind to all after the test. Change-Id: I39b373c07a2d5aa396f5c7602bffabab0481930f Signed-off-by: Philip Yang <Philip.Yang@amd.com>
