Comment 5 Mika Kuoppala 2016-02-04 16:06:55 UTC 
Bxt has aperture of size 256 terabytes (48bit vaddress space).

We need a mechanism to limit the aperture in these platforms to
allow eviction testing. As it would need machine with bigger physical
memory size than the 48bit aperture, for eviction to kick in.
Comment 6 Chris Wilson 2016-02-04 16:18:26 UTC 
(In reply to Rami from comment #4)
> Reproduced on BXT with last setup

Reproduced what? You didn't even copy the test output to indicate if you are still seeing the test bug.
Comment 7 Kimmo Nikkanen 2016-02-08 08:38:53 UTC 
In my understanding the tests are now are failing because we don’t have that 256 terabytes of memory on the device. The test outputs would most probably show that.

The only way to really test this today is to have a machine with more than 256 terabytes of memory. Only then you would be hitting the eviction mechanism. So this test would require some changes in order to work with our 48bit vaddress space.

Use uint64_t in eviction memory subtest parameters
Comment 9 Mika Kuoppala 2016-02-08 15:02:28 UTC 
Attached patch will make the tests not filling the memory requirements skip and not fail.

Eviction testing with 48bit address spaces is not possible yet

Hello Mika Kuoppala, i just applied your patch and it seems that "intel_os.c" needs to be modified as well.

We skip the test as we don't have enough ram to test.
