From dfe4a08ccddf5b9b6adf1e10510bb4534f36c459 Mon Sep 17 00:00:00 2001 From: Lucas Stach Date: Thu, 29 Mar 2018 16:15:14 +0200 Subject: [PATCH] gallium/util: implement util_format_is_yuv This adds a helper to check if a pipe format is in YUV color space. Drivers want to know about this, as YUV mostly needs special handling.
