Commit 42011be1e disabled HiZ when sharing depth buffer externally, which free HiZ buffer.
But in emit_depth_packets() we use that buffer, which generates a crash in "piglit.spec.egl_khr_gl_image.egl_khr_gl_renderbuffer_image-clear-shared-image gl_depth_component24" test when running in Skylake. This commit avoids using HiZ when the buffer was free. v2: detect earlier we don't have HiZ buffer (Jason) --- src/mesa/drivers/dri/i965/intel_fbo.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/mesa/drivers/dri/i965/intel_fbo.c b/src/mesa/drivers/dri/i965/intel_fbo.c index de0cd6aca2..aceeba3224 100644 --- a/src/mesa/drivers/dri/i965/intel_fbo.c +++ b/src/mesa/drivers/dri/i965/intel_fbo.c @@ -976,7 +976,7 @@ bool intel_renderbuffer_resolve_hiz(struct brw_context *brw, struct intel_renderbuffer *irb) { - if (irb->mt) + if (irb->mt && irb->mt->hiz_buf != NULL) return intel_miptree_slice_resolve_hiz(brw, irb->mt, irb->mt_level, -- 2.11.0 _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/mesa-dev
