From: Chia-I Wu Date: Tue, 9 Apr 2019 17:55:40 +0000 (+0000) Subject: virgl: handle fence_server_sync in winsys X-Git-Tag: upstream/19.3.0~7317 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=a23c091988f30fd432b5e1a68aedc95c307efa34;p=platform%2Fupstream%2Fmesa.git virgl: handle fence_server_sync in winsys It does not need help from the driver. This also fixes one issue where the fence is ignored when the transfer queue is full.
