Subject: [PATCH] drm: Introduce RGB 64-bit 16:16:16:16 float format
Date: Thu, 23 Nov 2017 16:56:55 +0800	[thread overview]
Message-ID: <1511427416-3216-1-git-send-email-tina.zhang@intel.com> (raw)

This patch is from "[PATCH v19 0/6] drm/i915/gvt: Dma-buf support for GVT-g":
https://lists.freedesktop.org/archives/intel-gvt-dev/2017-November/002508.html

The RGB 64-bit 16:16:16:16 float pixel format is needed by some Apps in
windows. The float format in each component is 1:5:10 MSb-sign:exponent:
fraction.

This patch is to introduce the format to drm, so that the windows guest's
framebuffer in this kind of format can be recognized and used by linux
host.
