Author: Eric Anholt <e...@anholt.net> Date: Mon Jul 27 23:23:57 2015 -0700 vc4: Fix raster surface shadow updates under DRI2. Glamor asks GBM for the handle of the BO, then flinks it itself. We were marking the bo non-private in the flink and dmabuf (DRI3) paths, but not the GEM handle path. As a result, non-pageflipping DRI2 swapbuffers (EGL apps, in particular) were never updating the texture. --- src/gallium/drivers/vc4/vc4_screen.c | 6 ++++++ 1 file changed, 6 insertions(+) diff --git a/src/gallium/drivers/vc4/vc4_screen.c b/src/gallium/drivers/vc4/vc4_screen.c index c069454..a20818d 100644 --- a/src/gallium/drivers/vc4/vc4_screen.c +++ b/src/gallium/drivers/vc4/vc4_screen.c @@ -490,6 +490,12 @@ vc4_screen_bo_get_handle(struct pipe_screen *pscreen, { whandle->stride = stride; + /* If we're passing some reference to our BO out to some other part of + * the system, then we can't do any optimizations about only us being + * the ones seeing it (like BO caching or shadow update avoidance). + */ + bo->private = false; + switch (whandle->type) { case DRM_API_HANDLE_TYPE_SHARED: return vc4_bo_flink(bo, &whandle->handle); _______________________________________________ mesa-commit mailing list mesa-commit@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-commit
