From 03bea8fda790592685d33743a5c9ce36b2fa91f0 Mon Sep 17 00:00:00 2001 From: Chad Versace Date: Fri, 12 Feb 2016 11:27:19 -0800 Subject: anv/meta_blit: Remove references to clearing Long ago, the blit code used to handle clearing and blitting. - Fix any comments that refer to clearing. - Rename shader var 'attr' to 'tex_pos'. The name 'attr' is an artifact of the time when the shader was used for blitting as well as clearing. --- src/vulkan/anv_meta_blit.c | 23 ++++++++++------------- 1 file changed, 10 insertions(+), 13 deletions(-) (limited to 'src') diff --git a/src/vulkan/anv_meta_blit.c b/src/vulkan/anv_meta_blit.c index 3a777705ef1..07ebcbc06b1 100644 --- a/src/vulkan/anv_meta_blit.c +++ b/src/vulkan/anv_meta_blit.c @@ -48,17 +48,14 @@ build_nir_vertex_shader(void) pos_out->data.location = VARYING_SLOT_POS; nir_copy_var(&b, pos_out, pos_in); - /* Add one more pass-through attribute.
