Hi,
There is something wrong about gem_tiled_blits. Timeout when running Intel_gpu_tools/gem_tiled_blits.
It's case regression. By bisected,371f87f2d825900484e34a8ec78272b9e62cbc02 is the first bad commit.
Information about this commit:
Commit 371f87f2d825900484e34a8ec78272b9e62cbc02
Author: Chris Wilson <chris@chris-wilson.co.uk<mailto:chris@chris-wilson.co.uk>>

Exercise the whole aperture with tiled blits
After full-gtt, gem_tiled_blits doesn't allocate enough to force
eviction. So query the total aperture and accommodate.
Also introduce a similar test that utilizes fences rather than
use the BLT to perform the tiling and detiling.

Takes around 30s to run the exercise on my i3. The fun part is that it
tries to allocate 3+ GiB of memory in order to cause the aperture
thrashing and so test evicting tiled buffers. If you don't have that much
memory available, then you get swap thrashing or even the dreaded OOM.
[I thought about limiting it to total available memory...]
Is your machine making any progress? Did the kernel send any warnings over
netconsole? How much memory do you have and what is your timeout?

My machine does not made progress. There is no warnings over netconsole. MemTotal in Piketon is about 1.8G. It takes about
5s when running gem_tiled_blits normally. Timeout means 90s,even exist in process continuously.
