[Intel-gfx] [PATCH] tests/gem_bad_address: Adapt test to ppgtt to pass with command parser

[Popov, Pavel E]

Hi Chris,

Thanks for quick response. 

I see that these tests from HANG section. 
Probably all tests with unclear behavior are put here.

But what is about the test gem_exec_bad_domains?
It also contains BAD_GTT_DEST with the same value.
This test isn't from HANG section.

Pavel

Heh, gem_bad_address is supposed to fail ;-)

As with gem_bad_blit, this is testing antiquated notions of what is
allowed: BAD_GTT_DEST is not what it claims to be.
