From: Michel Dänzer Date: Thu, 28 Sep 2006 14:02:05 +0000 (+0000) Subject: Make driDrawableInitVBlank() initialize the sequence number. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=24bb3b399847bdb11f0008820c2c1bad1e21d499;p=mesa.git Make driDrawableInitVBlank() initialize the sequence number. This prevents the first wait for vertical blank from timing out when the X server has been running for a long time. --- diff --git a/src/mesa/drivers/dri/common/vblank.c b/src/mesa/drivers/dri/common/vblank.c index eebe42d96a1..25b912e8242 100644 --- a/src/mesa/drivers/dri/common/vblank.c +++ b/src/mesa/drivers/dri/common/vblank.c @@ -208,20 +208,6 @@ GLuint driGetDefaultVBlankFlags( const driOptionCache *optionCache ) } -/****************************************************************************/ -/** - * Sets the default swap interval when the drawable is first bound to a - * direct rendering context. - */ - -void driDrawableInitVBlank( __DRIdrawablePrivate *priv, GLuint flags ) -{ - if ( priv->pdraw->swap_interval == (unsigned)-1 ) { - priv->pdraw->swap_interval = (flags & VBLANK_FLAG_THROTTLE) != 0 ? 1 : 0; - } -} - - /****************************************************************************/ /** * Wrapper to call \c drmWaitVBlank.
