X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=f53b6d0134d9ad66e8ec3d7c09daaba8192834be;p=mesa.git Releasing a surfaceless EGL context doesn't release underlying DRI context. driUnbindContext() checks for valid drawables before calling the driver unbind function. In case of Surfaceless contexts, the drawables are always Null and we end up not releasing the underlying DRI context. Moving the call to the driver function before the drawable validity checks fixes things. Steps to trigger this bug are following: - create surfaceless context and make it current - make some other context current - {another thread} destroy surfaceless context - make another context current Signed-off-by: Alexandros Frantzis Signed-off-by: Kalyan Kondapally Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=74563 --- diff --git a/src/mesa/drivers/dri/common/dri_util.c b/src/mesa/drivers/dri/common/dri_util.c index 6c78928ee7d..02499f2daec 100644 --- a/src/mesa/drivers/dri/common/dri_util.c +++ b/src/mesa/drivers/dri/common/dri_util.c @@ -569,6 +569,12 @@ static int driUnbindContext(__DRIcontext *pcp) if (pcp == NULL) return GL_FALSE; + /* + ** Call driUnbindContext before checking for valid drawables + ** to handle surfaceless contexts properly. + */ + pcp->driScreenPriv->driver->UnbindContext(pcp); + pdp = pcp->driDrawablePriv; prp = pcp->driReadablePriv; @@ -576,8 +582,6 @@ static int driUnbindContext(__DRIcontext *pcp) if (!pdp && !prp) return GL_TRUE; - pcp->driScreenPriv->driver->UnbindContext(pcp); - assert(pdp); if (pdp->refcount == 0) { /* ERROR!!! */
