Subject: drm/radeon/kms: remove benchmarks shorter than one page
X-Git-Tag: v3.4-rc1~143^2~116
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=6d75e83ee31c146c8a3d56c762d3e15c483dc40e;p=pandora-kernel.git

drm/radeon/kms: remove benchmarks shorter than one page

copy_blit operation works only on integral number of pages
so benchmarks shorter than one page size (4K) do not make sense

v2: use RADEON_GPU_PAGE_SIZE instead of "magic" 1024 number and
    sweep sizes between 1 * <page_size> to 16K * <page_size> doubling
    the size in each iteration; we get the same coverage, as
    in the original benchmark, but guarantee integer multiples
    of page size

v3: add whitespace between '*' operator per review received from
    zajec5@gmail.com
