From: Mike Blumenkrantz Date: Mon, 1 Jun 2020 14:53:19 +0000 (-0400) Subject: zink: use u_transfer_helper to split/merge interleaved depth/stencil formats X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=d84a75466c9d0df78370675421472afe5663b4e9;p=mesa.git zink: use u_transfer_helper to split/merge interleaved depth/stencil formats EXT_packed_depth_stencil adds GL_UNSIGNED_INT_24_8_EXT which is an interleaved format, but vulkan spec states that reading/writing the corresponding format provides only the D24 component, which requires that we perform separate operations for each component using separate buffers fixes mesa/mesa#3031 Reviewed-by: Erik Faye-Lund Part-of: --- diff --git a/src/gallium/drivers/zink/zink_batch.c b/src/gallium/drivers/zink/zink_batch.c index 2b92b1a540a..aad6ef958bb 100644 --- a/src/gallium/drivers/zink/zink_batch.c +++ b/src/gallium/drivers/zink/zink_batch.c @@ -111,6 +111,15 @@ zink_batch_reference_resoure(struct zink_batch *batch, if (!entry) { entry = _mesa_set_add(batch->resources, res);
