[igt-dev] [PATCH i-g-t] i915/gem_mmap_gtt: Trim object size for ptracing

[Chris Wilson]

For verifying vm_ops.access we only need a page or two to check we both
advance across a page boundary and find the right offset within a page.
16MiB is overkill for the slow uncached reads through the slow ptrace
interface, so reduce the object size by a couple of orders of magnitude.

Re: [igt-dev] [PATCH i-g-t] i915/gem_mmap_gtt: Trim object size for ptracing

[Mika Kuoppala]

Chris Wilson <chris@chris-wilson.co.uk> writes:
