From 1cfd769c2ec0b605cacd75c0e9c89346e1f9518d Mon Sep 17 00:00:00 2001 From: Jesse Barnes Date: Wed, 13 Jan 2010 19:01:51 -0500 Subject: [PATCH] DRI2: don't send DRI2 requests the server doesn't know about At init time, NULL out the hooks that send the server new requests. DRI2 never supported these extensions, so this preserves old behavior on old servers with new Mesa. --- src/glx/x11/dri2_glx.c | 18 +++++++++++++----- 1 file changed, 13 insertions(+), 5 deletions(-) diff --git a/src/glx/x11/dri2_glx.c b/src/glx/x11/dri2_glx.c index e1688f38fff..7b0c52b50d4 100644 --- a/src/glx/x11/dri2_glx.c +++ b/src/glx/x11/dri2_glx.c @@ -575,11 +575,19 @@ dri2CreateScreen(__GLXscreenConfigs * psc, int screen, psp->swapBuffers = dri2SwapBuffers; psp->waitGL = dri2WaitGL; psp->waitX = dri2WaitX; - psp->getDrawableMSC = dri2DrawableGetMSC; - psp->waitForMSC = dri2WaitForMSC; - psp->waitForSBC = dri2WaitForSBC; - psp->setSwapInterval = dri2SetSwapInterval; - psp->getSwapInterval = dri2GetSwapInterval; + if (pdp->driMinor >= 2) { + psp->getDrawableMSC = dri2DrawableGetMSC; + psp->waitForMSC = dri2WaitForMSC; + psp->waitForSBC = dri2WaitForSBC; + psp->setSwapInterval = dri2SetSwapInterval; + psp->getSwapInterval = dri2GetSwapInterval; + } else { + psp->getDrawableMSC = NULL; + psp->waitForMSC = NULL; + psp->waitForSBC = NULL; + psp->setSwapInterval = NULL; + psp->getSwapInterval = NULL; + } /* DRI2 suports SubBuffer through DRI2CopyRegion, so it's always * available.*/ -- 2.30.2
