X-Git-Tag: accepted/tizen/unified/20200303.032539~2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=refs%2Fchanges%2F49%2F224849%2F2;p=platform%2Fcore%2Fuifw%2Flibtdm.git

tdm_virtual: use tdm.ini flag to select virtual hwc target buffer bo type

use virtual_output_hwc_target_bo_default flag.
if set to 1, use TBM_BO_DEFAULT flag to make hwc target buffer queue.
if set to 0 or not defined, use TBM_BO_SCANOUT flag.
