From 77e0523fb7769df4bf43747e136b1653b2421b97 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Thu, 4 Oct 2007 12:07:25 -0700 Subject: [965] Replace various alignment code with a shared ALIGN() macro. In the process, fix some alignment issues: - Scratch space allocation was aligned into units of 1KB, while the allocation wanted units of bytes, so we never allocated enough space for scratch. - GRF register count was programmed as ALIGN(val - 1, 16) / 16 instead of ALIGN(val, 16) / 16 - 1, which overcounted for val != 16n+1. --- src/mesa/drivers/dri/i965/intel_context.h | 2 ++ 1 file changed, 2 insertions(+) (limited to 'src/mesa/drivers/dri/i965/intel_context.h') diff --git a/src/mesa/drivers/dri/i965/intel_context.h b/src/mesa/drivers/dri/i965/intel_context.h index f63c2f613d..65898caaa7 100644 --- a/src/mesa/drivers/dri/i965/intel_context.h +++ b/src/mesa/drivers/dri/i965/intel_context.h @@ -252,6 +252,8 @@ void UNLOCK_HARDWARE( struct intel_context *intel ); #define SUBPIXEL_X 0.125 #define SUBPIXEL_Y 0.125 +#define ALIGN(value, alignment) ((value + alignment - 1) & ~(alignment - 1)) + /* ================================================================ * Color packing: */ -- cgit v1.2.3
