From: Jordan Justen Date: Tue, 26 Jan 2016 19:10:56 +0000 (-0800) Subject: anv: Support swizzled formats. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=c20f78dc5d7e0fabd58c2d8548d5a6ead1ec1072;p=mesa.git anv: Support swizzled formats. Some formats require a swizzle in order to map them to actual hardware formats. This allows us to turn on two new Vulkan formats. --- diff --git a/src/vulkan/anv_formats.c b/src/vulkan/anv_formats.c index 2cfcac45b9b..30e865c39b6 100644 --- a/src/vulkan/anv_formats.c +++ b/src/vulkan/anv_formats.c @@ -26,15 +26,22 @@ #include "gen7_pack.h" -#define fmt(__vk_fmt, __hw_fmt, ...) \ +#define RGBA ((struct anv_format_swizzle) { 0, 1, 2, 3 }) +#define BGRA ((struct anv_format_swizzle) { 2, 1, 0, 3 }) + +#define swiz_fmt(__vk_fmt, __hw_fmt, __swizzle, ...) \ [__vk_fmt] = { \ .vk_format = __vk_fmt, \ .name = #__vk_fmt, \ .surface_format = __hw_fmt, \ .isl_layout = &isl_format_layouts[__hw_fmt], \ + .swizzle = __swizzle, \ __VA_ARGS__ \ } +#define fmt(__vk_fmt, __hw_fmt, ...) \ + swiz_fmt(__vk_fmt, __hw_fmt, RGBA, __VA_ARGS__) + /* HINT: For array formats, the ISL name should match the VK name.
