Description Mark Janes 2016-05-31 23:59:08 UTC
bac39dd regressed this test:
mesa/xfb: report calculated size for XFB buffer objects.

This fixes:

This test looks correct to me, we should work out the
size value and report it rather than using only the size
from the Range interface.

    dsa/xfb: make the buffer large enough.
    This bug in the test was triggered by a fix to mesa, the test creates
    a backing buffer smaller than the xfb range it requests then is surprised
    when it gets returned a truncated value for the size.
