Subject: intel_upload_blit_*: Fix reporting and generate junk instead of using random.
X-Git-Tag: 1.0~19
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=7889abd2631b418d4bb9fb90a758f23f37d2f098;p=profile%2Fextras%2Fintel-gpu-tools.git

intel_upload_blit_*: Fix reporting and generate junk instead of using random.

Turns out that random completely overwhelmed the cost of the driver stuff
in _large.c.  I definitely want to generate data, but still be able to see
the driver's responsibility.
