Subject: st/vdpau: add flush on unmap
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=db54fca9b86aa124447d11d2bdbe359a2742cfd5;p=mesa.git

st/vdpau: add flush on unmap

Flush the context when we unmap a buffer, otherwise VDPAU might
start rendering the next frame while we still reference that buffer.
