[Intel-gfx] [RFC i-g-t 4/6] tests/gem_stolen: drop gem_stolen.c

Daniele Ceraolo Spurio daniele.ceraolospurio at intel.com
Mon Oct 2 23:00:16 UTC 2017


The feature was never merged and there has been no progress in the
last year. The subtests are currently skipping on all platforms by
checking a field in the get_aperture ioctl structure that doesn't
exist in the kernel version of the struct.
