From f93b6d8cc5b0e3830e0c095772795e606fd1fe3a Mon Sep 17 00:00:00 2001 From: Richard Sandiford Date: Mon, 21 Jul 2014 16:32:38 +0100 Subject: [PATCH] util: Add big-endian layout for a number of formats. This patch builds on 6c8f547f66e68b495c708f8ffcb67370caa5ffe8 and previous patches by allowing u_format.csv to specify separate big-endian and little-endian layouts. It then uses this to specify the correct layouts for various depth/stencil formats. Later patches handle other formats. To recap, the idea is that u_format.csv lists the channels for an N-byte value as though it were an N-byte integer. For little-endian targets the channels are listed starting at the least-significant bit of the integer while for big-endian targets the channels are listed starting at the most-significant bit. This means that for something like PIPE_FORMAT_B8G8R8A8_UNORM (blue in first byte of memory, alpha in last byte of memory) the orders are the same for both endiannesses. But for something like PIPE_FORMAT_S8_UINT_Z24_UNORM, where the stencil is in the least significant byte of a 32-bit integer, there need to be separate channel definitions for each endianness. The effect of this patch is to make the affected PIPE_FORMAT_*s have the same layout as the associated MESA_FORMAT_*s for big-endian. The MESA_FORMAT_*s are already handled correctly. Fixes various piglit tests on z. No regressions on x86_64.
