Author: Kristian Høgsberg <[email protected]> Date: Tue May 18 14:45:10 2010 -0400 dri2_glx: Put the invalidate b/c code back in The backwards compatibility code calls the DRI driver invalidate hook on swap buffer and flush front buffer. This lets the DRI driver rely on invalidate callbacks and drop the glViewport() hack, even if the server doesn't send invalidate events. This is essentially a revert of 2d00d16da7f5d2255cb37b48edaf4cbb9ca7e930, except that we now also pass the __DRI_USE_INVALIDATE extension even when the server doesn't have DRI2 invalidate events. --- src/glx/dri2_glx.c | 19 +++++++++++++------ 1 files changed, 13 insertions(+), 6 deletions(-) diff --git a/src/glx/dri2_glx.c b/src/glx/dri2_glx.c index 17352e9..4595991 100644 --- a/src/glx/dri2_glx.c +++ b/src/glx/dri2_glx.c @@ -361,6 +361,14 @@ dri2WaitGL(__GLXDRIdrawable * pdraw) static void dri2FlushFrontBuffer(__DRIdrawable *driDrawable, void *loaderPrivate) { + __GLXDRIdrawablePrivate *pdraw = loaderPrivate; + __GLXdisplayPrivate *priv = __glXInitialize(pdraw->base.psc->dpy); + __GLXDRIdisplayPrivate *pdp = (__GLXDRIdisplayPrivate *)priv->dri2Display; + + /* Old servers don't send invalidate events */ + if (!pdp->invalidateAvailable) + dri2InvalidateBuffers(priv->dpy, pdraw->base.drawable); + dri2WaitGL(loaderPrivate); } @@ -421,16 +429,16 @@ dri2SwapBuffers(__GLXDRIdrawable *pdraw, int64_t target_msc, int64_t divisor, (*pdraw->psc->f->flush)(pdraw->driDrawable); #endif + /* Old servers don't send invalidate events */ + if (!pdp->invalidateAvailable) + dri2InvalidateBuffers(dpyPriv->dpy, pdraw->drawable); + /* Old servers can't handle swapbuffers */ if (!pdp->swapAvailable) { dri2CopySubBuffer(pdraw, 0, 0, priv->width, priv->height); return 0; } - /* Old servers don't send invalidate events */ - if (!pdp->invalidateAvailable) - dri2InvalidateBuffers(dpyPriv->dpy, pdraw->drawable); - #ifdef X_DRI2SwapBuffers DRI2SwapBuffers(pdraw->psc->dpy, pdraw->xDrawable, target_msc, divisor, remainder, &ret); @@ -737,8 +745,7 @@ dri2CreateDisplay(Display * dpy) pdp->loader_extensions[i++] = &systemTimeExtension.base; #ifdef __DRI_USE_INVALIDATE - if (pdp->invalidateAvailable) - pdp->loader_extensions[i++] = &dri2UseInvalidate.base; + pdp->loader_extensions[i++] = &dri2UseInvalidate.base; #endif pdp->loader_extensions[i++] = NULL; _______________________________________________ mesa-commit mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/mesa-commit
