Subject: radv: Use the syncobj wait ioctl to wait on fences if possible.
X-Git-Tag: android-x86-8.1-r1~5160
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=f9898b211eb23c18d27508a2cbbdd629fc3dc734;p=android-x86%2Fexternal-mesa.git

radv: Use the syncobj wait ioctl to wait on fences if possible.

Handles the !waitAll and signal after the start of the wait cases correctly.
