Subject: mesa/xfb: report calculated size for XFB buffer objects.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=bac39dddcf28d9d2df2f60c8dbb384c54366ed73;p=mesa.git

mesa/xfb: report calculated size for XFB buffer objects.

This fixes:
GL45-CTS.direct_state_access.xfb_buffers

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.
